Authorization to Distribute Revised AUAR for Valley Green Corporate Center CONSENT CITY OF SHAKOPEE IS: fJ, /, Memorandum CASELOG NO.: TO: Mayor and City Council Mark McNeill, City Administrator FROM: R. Michael Leek, Community Development Director SUBJECT: Distribution of Revision to Alternative Urban Area wide Review for Valley Green Corporate CenterlDean's Lake Residential MEETING DATE: May 20, 2003 INTRODUCTIONIDISCUSSION: Ryan Development has proposed changes in the concept plan for development of the subject site. Principal among these is an increase in the number of residential units proposed as part of the project. Because of those changes, a draft revision to the AUAR for the site has been prepared. Council is asked to authorize distribution ofthe revision for the requisite review and comment period. While there have been further revisions in the concept plan that currently put the number of residential units at 499, the analysis in the revision is based on 565 units. The reason for that is that the analysis based on the larger number of units will also suffice if the number of units is somewhat less At the close of the review period, staff and WSB will prepare any responses to comments or amendments required to the document. It will then be sent out for a 1 O-day period during which "reviewing agencies" can file objections. Based on the fact that none were received for the last revision to the AUAR, it seems unlikely that any objections would be received to this revision. AL TERNATIVES: 1. Offer and pass a motion authorizing the distribution of the Revision to the AUAR for Valley Green Corporate Center for review and comment per Minnesota Rules. 2. Do not authorize distribution, and provide direction to staff and WSB as to any changes the Council wishes to have made before distribution. . ACTION REQUESTED: Offer and pass a motion authorizing the distribution ofthe Revision to the AUAR for Valley Green Corporate Center for review and comment per Minnesota Rules. /'f' A;A'.v~L R.

Re: Revised AUAR for the Valley Green Corporate Center Site City of Shakopee, ~ WSB Project No. 1281-54 . Dear Honorable Mayor, City Council, and Staff: We have completed our revisions to the Alternative Urban Areawide Review (AUAR) environmental document for the proposed Valley Green Corporate Center development in the City of Shakopee. The AUAR document was modified to reflect the proposed land use changes presented by Ryan Companies earlier this year. Land use changes anticipate converting approximately 800,000 square feet of commercial, industrial, warehouse space to medium-density residential within the Valley Corporate Center site. The Valley Green Corporate Center site is located in the southeast quadrant of the intersection of Trunk Highway 169 and County Road 83. Attached for your review and your consideration for authorizing distribution is the revised AUAR document to reflect the proposed changes in land use at the Valley Green Corporate Center site.

SHAKOPEE May 2003 Alternative Urban Areawide Review Revision Valley Green Corporate Center / Deal's Lake Residential May 2003 Executive Summary Purpose of Alternative Urban Areawide Review (AUAR Revision) Ryan Companies US, Inc. (Ryan) has become the master developer of the 265-acre mixed use Valley Green Corporate Center and Dean's Lake Residential (Valley Green) project. The project is located south of Trunk Highway 169 (TH 169), east of County State Aid Highway (CSAR 83) and adjacent to Dean's Lake (Figure i-Vicinity Map). The natural features associated with the property include Dean's Lake, wetlands and buffer areas, and remnant forest. Valley Green is envisioned as a mixed-use development that includes a variety of business, commercial and residential land uses with measures to protect and incorporate the natural features within the site. Why Revise the Approved AUAR In April 2003, Ryan Companies proposed additional modifications to the development plan proposed in the 2002 FAUAR by reducing some of the office/warehouse land use and replacing it with medium density residential. These changes will involve a land use and zoning change to be approved by the City Council and Metropolitan Council prior to development. Prior to consideration of these changes by the City Council, this update to the AUAR has been prepared to study the impacts to the area due to the proposed changes. Proiect Description I Historv In June of 200 1, the City of Shakopee approved a preliminary plat for development of a business park, referred to as Valley Green Corporate Center. AB part ofthe planning process, an Alternative Urban Areawide Review (AUAR) was prepared for the property. The City approved the fmal AUAR in July of 2000. In July of2001, Ryan Companies entered into a purchase agreement with the property owners of Valley Green. As Ryan began to analyze the site and the previously approved plat, they detemiined that the site could be developed differently to establish a better relationship with the enviromnental features located on the site and the surrounding land uses. To create this relationship, Ryan, the City, and the City's consultant, Brauer and Associates, worked collaboratively to create a mixed-use development. In 2003, Ryan developed a concept plan that reduced the amount of commerciallbusiness park and increase the amount of medium-density housing. Due to this land use change that will also require a zoning change, the City decided to revise the AUAR. The 2003 AUAR includes the analysis from the 2002 AUAR (Option A) and analysis for the newly proposed option (Option B) as described below: Option A: This option was reviewed as part of the July 2002 AUAR and includes 2,000,000 - 2,100,000 square feet of commercial/office space and 258 attached residential units on 265 acres. The discussion provided in this AUAR is generally the discussion that was provided and reviewed as part of the July 2002 AUAR. Option B: This option includes approximately 1,300,000 square feet of commercial/office space, 565 townhome units (364 attached residential units and 106 unattached units) on 265 acres. AUAR Revision . Valley Green Corporate Center/Dean's Lake Residential May 2003 Page 2 of 6 A major component of both Option A and B is the creation of a greenway, which circulates through the commercial and residential components of the property. This greenway will include wildlife habitat, ecological restoration areas, innovative stormwater treatment areas and pedestrian trails that link together different components of the development. In addition to the greenway, an ecological protection zone around the lakeshore has been established which exceeds the width and function requirements of the City. The built environment is compressed as a result of providing the greenway and lake shore protection zone. This was accomplished by reducing building setbacks and street right-of-way widths that are typical for this type of development. Community Values/Conservation Development During the concept design process, the City and Ryan Companies undertook a collaborative process to implement the community values identified in the "Lake Area Master Plan" created by the City for the Dean's Lake area. This collaborative process was undertaken to implement particular values identified in the document. The following are some of the community values identified in the 'Lake Area Master Plan' used to help defme and develop the Valley Green site plan: . Preserve natural features, habitat, and open space; . Maintain ecological protection zone along lakeshore; . Develop an ecological-based approach to stormwater management; . Maximize park and trail opportunities; . Develop an ecological and omamentallandscape stewardship program; . Manage traffic demand; . Maximize economic benefit; . Maximize job creation. Existina Land Uses/Comprehensive Plan References The City of Shakopee's Comprehensive Plan and Zoning Map designates two land uses for the property (see Figure 5). The westerly third of the property is designated Commercial while the remainder of the property is designated Business Park. Surrounding land uses include TH 169 (Shakopee Bypass) to the north, CSAH 83 (Canterbury Downs Boulevard) to the west, CSAH 16, (Eagle Creek Boulevard), to the south, Dean's Lake and single family homes to the south, and undeveloped wetlands associated with Dean's Lake to the east. The Southbridge residential development is beyond the wetlands to the east. Property to the north of:rH 169 has been developed for commercial uses. Property to the west ofCSAH 83 is undeveloped and designated Commercial in the Comprehensive Plan. The property has been rough graded in anticipation of the previously approved preliminary plat in the areas adjacent to TH 169 and CSAH 83. Dean's Lake and the associated wetlands and woodlands occupy the south and east portion of the property. The topography of the property is relatively flat, except along the southerly property line where an existing bluff line is located along CSAH 16. Groundwater and bedrock on the property varies from three to twenty feet below the surface. Proposed Land Uses . Ryan will be requesting modification to the land use designations of the property to include Medium-Density Residential uses and to eliminate the Commercial land. The Pllrpose for eliminating the Commercial land use is to allow for uses that will naturally migrate to the property because of the existing urban infrastructure, environmental features, and the proposed amenities envisioned for Valley Green. AUAR Revision Valley Green Corporate Center/Dean's Lake Residential May 2003 Page 3 of 6 . Traffic Analvsis The property is lacated at the intersection af Trunk Highway 169 (TH 169) and Caunty State Aid Highway 83 (CSAH 83), with CauntyState Aid Highway 16 (CSAH 16) located to. the sauth afthe site. It is propased to. include a mix af retail uses, affice/warehause uses and residential uses. This is a departure fram the ariginal planned land use, which included a mix af retail and affice/warehause. Camparisan of the trip generatian estimates of the previausly prapased Valley Green Business Park versus Option A indicate that the current praposal generates 9,059 fewer vehicles trips per day and will generate abaut 72 percent af the AM and PM peak hour demand estimated for the earlier Valley Green proposal. Option A will result in less traffic, and surraunding intersectians will aperate at a LOS D ar better during critical PM peaks under full build-out conditians. Far Optian B, given that the current traffic generation prajections (16,982 Net Tatal Trips) are approximately 25% less than thase included in the July 2002 AUAR (22,701 Net Tatal Trips) which were 29% less than those included in the July 2000 AUAR (31,760 Net Total Trips), it is concluded that Option B wauld have measurably less detrimental enviranmental impacts than were included in the accepted AUAR fram July, 2000. The City af Shakapee is currently not served by the Metrapalitan Transit Service. Instead, the City af Shakopee is the pravider thraugh Shakopee Area Transit (SAT) alternative transit services. The services currently provided are: (1) dial-a-ride service within the City af Shakapee; (2) cammuter vanpoals. Express bus service to. Eden Prairie Center is expected to be reinstated this year. The transit ridership levels averall have been steadily increasing. With the apening af the new Blaomingtan Ferry Bridge and US 169, the pace af development in Shakopee has increased significantly. In arder to meet increased demand, the City will need to. work with ather transit praviders to ensure that its residents can make the transit cannectians, they need to. get acrass the metrapalitan area to jabs and ather destinatians. With the increased residents and development araund the area afthe US 169 and CSAH 83 andwith CSAH 17, the City has identified the need far a park-and-ride site in these areas. A park-and-ride facility has been identified in the northwest quadrant of US 169 and CSAH 83 and in the narthwest quadrant of US 169 and CSAH 17. The City will be cammitted to. wark with Valley Green COIporate Center to encaurage carpools and vanpools (within) the prapased site, as it develops." From the results af the analyses, it is concluded that no. mitigatian measures will be necessary far either the 2010 ar 2020 projected build years. Hawever, it is suggested that aperatians at all intersectians studied be monitared in the future to. determine if any raad improvements become necessary. Vehicle-Related Air Emissions As part af the ariginal AUAR, vehicle-related air emissians were analyzed to. determine if adverse air quality impacts wauld accur upan build aut of the praject. Based upon the carban manaxide (CO) emissions and dispersion analysis, it was determined that the I-hour and 8-haur cancentratians were below established standards and no. significant adverse air quality impacts would accur. A detailed vehicle related air emissians analysis was campleted as part afthe Final Alternative Urban Area Wide Review document prepared for the development in July 2000 (July 2000 F AUAR). Far AUAR Revisian Valley Green Corporate Center/Dean's Lake Residential May 2003 Page 4 af 6 purposes of responding to this section of the Revised AU AR, results ofthe vehicle related air emissions analysis completed for the July 2000 F AUAR were used. The analysis that was included in the 2002 AUAR is included in the 2003 AUAR as Option A. Additional analysis for Option B has also been added to the 2002 AUAR. The results ofthe analysis for Option A indicated that background carbon monoxide levels added to vehicle related air emissions model resulted in the ultimate exposure of receptors to carbon monoxide levels resulting from the proposed development. Understanding that modeled and background levels for the proposed development under this Amended AUAR will be less than those determined for the development proposed under the July 2000 F AUAR, and that ultimate levels determined under the July 2000 F AUAR are below state exposure limits, ultimate carbon monoxide levels for Option A will be less than state exposure limits. Since the results of the analysis for Option A concluded that no significant adverse Air Quality impacts would be expected and Option B will generate approximately 25% less total trips at full build than Option A, it can be concluded that the proposed project win not have any significant adverse Air Quality impacts. Noise Analvsis . Noise levels were analyzed for Option B with the previous 2002 AUAR analysis being used for Option A. The model was run with two receptors, south and northeast. The south receptor (Rl) was located just south of the proposed residential area near CSAH 16, the northeast receptor (R2) was located near the northeast comer of the proposed residential area. Worst case conditions (peak hour traffic) were used for the model runs. The site currently has a tree line along CSAH 16 and this area will remain once development is complete. The noise model for Option A in the 2002 AUAR indicated that noise levels will be below state standards under 2017 build and traffic conditions. The analysis for Option B also indicated that noise levels will be below state standards under full-build and traffic conditions. However, this are is currently zoned commercial/business park and as such, the above analysis meets the noise standards for this area. However, a change in zoning of this area from commercial to residential will lower the noise threshold standards. Therefore, the traffic associated with the surrounding roads and the development have the potential to exceed these noise threshold standards. As part of the development, mitigation measures for the noise will be included Watermain The City of Shakopee Public Utility Commission (SPUC) will furnish the public water supply to Valley Green Corporate Center. Water will be provided to the site via l2-inch watermain from existing trunk lines located in the right-of-ways of County State Aid Highways 16 and 83, and State Highway 169. The original AUAR estimated the MUSA's water demand for 554 acres of developable land SQuth of Highway 169 to be 660,000 GPD. Of the 554 acres considered, Valley Green Corporate Center encompasses approximately 265 acres or 48% of the total area, this equates to a demand of 316,800 GPD (660,000 x 48%). For planning purposes, the estimated water demand to supply Option A is approximately 218,000 GPD. The estimated water demand to supply Option B is approximately 245,810 GPD. . Sanitary Sewer Valley Green falls within the Metropolitan Urban Service Area (MUSA) expansion area granted by the Metropolitan Council to the City of Shakopee in 1999. Wastewater from Valley Green will be routed to the adjacent Chaska interceptor (located within the right-of-way of State Highway 169), then collected and treated by the Metropolitan Council-Environmental Services Division. For planning purposes, it is AUAR Revision Valley Green Corporate Center/Dean's Lake Residential May 2003 Page 5 of 6 . estimated that Option A will generate approximately 2l8,000GPD and Option B will generate approximately 245,8l0GPD. , Erosion Control/Stormwater Manaaement/Water Oualitv Best Management Practices (BMP's) will be used during construction to manage erosion control. Storm water will be managed on-site through a series of infiltration and ponding areas for both options. Runoff rates will be controlled to conform to the Comprehensive Stormwater Management Plan. Stormwater ponds and infiltration areas will be utilized to manage water quality in compliance with the City requirements for storm water entering Dean Lake. Stormwater management and water quality will be enhanced through implementation of low impact design where possible. The proposed water quality and rate control is consistent with the original ADAR. physical Impacts on Water Resources According to the 2000 ADAR, wetland impacts totaled 0.52-acres. For both Options A and B, additional impacts of 1.29-acres are anticipated. STS Consultants per their January 27, 1998 report identified wetlands. Following is a summary ofthe impacted wetlands. 2000 AUAR-Valley Green Cor orate Center Wetland 1m acts Wetland ID Acres Filled Comments 26- WM 0.23 Monot ic stand of canary reed ss with relict hummocks. 29-MS 0.29 Bulrush marsh with poplar fringe.

AUAR Revision Valley Green Corporate Center/Dean's Lake Residential May 2003 Page 6 of 6 , DRAFT Introduction & Summary A. Introduction A Final Alternative Urban Area-Wide Review (F AUAR) was adopted by the City of Shakopee on July 16, 2000 for the area known as Valley Green Corporate Center (VGCC). Subsequently, Ryan Companies US, Inc. became the master developer ofthe site and proposed modifications to the original development plan. A Supplement to the F AUAR was prepared and adopted in July, 2002. The supplement discussed the changes in potential environmental impacts, alternatives, and mitigative measures, as discussed in the F AUAR. In Apri12003, Ryan Companies proposed additional modifications to the development plan proposed in the 2002 FAUAR by reducing some of the office/warehouse land use and replacing it with medium density residential. These changes will involve a land use and zoning change to be approved by the City Council and Metropolitan Council prior to development. Prior to consideration of these changes by the City Council, this update to the AUAR has been prepared to study the impacts to the area due to the proposed changes. This AUAR outlines two development options. The first option (Option A) is the development plan outlined and reviewed as part of the July 2002 AUAR. The second option (Option B) is the proposed option that includes additional townhomes and less office/warehouse space than the July 2002 AUAR. These options are briefly described below: Option A: This option was reviewed as part of the July 2002 AUAR and includes 2,000,000 - 2,100,000 square feet of commercial/office space and 258 attached residential units on 265 acres. The discussion provided in this AUAR is generally the discussion that was provided and reviewed as part ofthe July 2002 AUAR. Option B: This option includes approximately 1,300,000 square feet of commercial/office space, 565 townhome units (364 attached residential units and 106 unattached units) on 265 acres. These proposed options provide for the area to be developed into a business center to stimulate economic development, and community growth, while conserving natural resources as originally reviewed in the past AUAR documents. The business park will contain a mix of office, warehouse, light industrial and residential sites within the 265-acre site. It should be noted that the past AUAR's reviewed a 332-acre site. Some reduction in project area has occurred due to an updated boundary determination and right-of-way dedications. The project area for both options has been reduced from 332 acres to 265 acres. B. General Format Utilized in this Document To provide ease in reviewing Option B and to provide a comprehensive environmental review document, both Option A andB are discussed throughout this updated AUAR. The discussion provided for Option A is nearly the same as the discussion provided as part of the previous City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 1 , AUAR documents for this development. In general, no subst~tive change to the Option A discussion has been made as part of the development of this updated AUAR. Changes have only been made in some areas of the discussion of Option A to clarify or provide additional information as needed. This updated AUAR has been developed to publicize the necessary revisions through the AUAR process in order: . to offer all interested parties ample opportunity to comment, and . to meet the requirements of the Minnesota's Environmental Review Rules c. Individual Subject (Question) Format Where applicable, responses to the questions indicate which option is being discussed and whether the text came from the 2000 AUAR, 2002 AUAR, new information, or contains revisions. The text for the Option B analysis is new. For those unfamiliar with the use of [sic]: Occasionally when direct quotes are used, the original quote may have contained: . Misspellings .

DESCRIPTION 6. Description. Instead of the information called for on the form, the description section of an A UAR should include the following elements for each major development scenario included: - anticipated types and intensity (density) of residential and commercia/lwarehouse/light industrial development throughout the AUAR area; - infrastructure planned to serve development (roads, sewers, water, storm water system, etc.) Roadways intended primarily to serve as adjoining land uses within an AUAR area are normally expected to be reviewed as part of an AUAR. More "arterial"types of roadways that would cross an AUAR area are an optional inclusion in the AUAR analysis; if they are to he included, a more intensive level of review, generally including an analysis of alternative routes, is necessary; _. information about the anticipated staging of various developments, to the extent known, and of the infrastructure, and how the infrastructure staging will influence the development schedule. Option A (Information from the July 2002 AUAR) a. The project proposes the creation of a business center to stimulate a balance of economic and community development with provision for medium density residential housing while conserving the natural ambiance of Dean's Lake. The business park will contain a mix of 2, 1 00,000 sf of office, warehouse and light industrial sites as shown on FIGURE 3a. Refer to Proposed Land Use Plan FIGURE 3b. The Option A layout maintains portions of the original street patterns, b. The residential portion of the project will consist of approximately 250 owner-occupied homes ranging in price from $ 175,000 to $ 220,000. The character of the units is anticipated to include: . Townhouses designed offer a more neighborhood appearance with front stoops fronting on the streets and placing vehicular access to the rear of the units. . A three level townhouse that offers generous living areas. . A condominium that provides two-story and single-level living options. c. Subsequent to the July 2000 AUAR, the City employed the services of Brauer & Associates to assist in overall planning activities which included the West Dean's Lake Area. Documentation of the conclusions reached in these endeavors is shown in APPENDIX C and D. A full copy of the Dean's Lake Area Parks, Open Space, and Trails Master Plan is available upon request. Ryan Companies, who have assumed the role of primary developer of the property participated in these planning efforts. d. Two significant variations from the previous layout discussed in the 2000 AUAR are addressed herein: . Option A includes the construction of stormwater infiltration areas throughout the site as shown in City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 4 ,I FIGURE 14. Rainfalls which exceed the capacity of these areas to store and infiltrate will overflow and be directed to the K-Mart Linear Pond on the north side of US 169. The City designed and constructed this pond to accommodate the VGCC area and areas further south. . Natural Open Space Conservation Areas have been relocated from strictly adjacent to Dean's Lake to extend throughout the development as shown on FIGURE 3a. Th~s concept may require that formal easement rights as a natural area be granted to the City and the City will have to be willing to accept them. It will further necessitate that the City review, and adjust if necessary, its ordinances which may call for tightly groomed lawns. The City must also maintain vigilance that individual occupants of the area do not disturb these Natural Open Space Conservation Areas. These concepts are discussed in the Community Value Statement for Valley Green Development / West Dean's Lake Area in the APPENDIX C. e. Potable water to serve the proposed center will be provided by extensions of the water distribution system with approval by the Shakopee Public Utility Commission. Wastewater generated by the site will be collected and treated by the Metropolitan Council- Environmental Services Division. Refer to FIGURES lla and b for detailed routing of potable watermains and sanitary sewer lines. f. All stormwater collection and management discussion is contained in ITEMS 12, 17, and 18. g. Previously, a formal grading plan for VGCC was prepared and submitted to the City on September 21, 1999. Subsequently, it was approved on September 22, 1999. Significant portions of the work shown on that plan were accomplished prior to the. acceptance of the F AUAR in July 2000. h. The City of Shakopee is also concluding the reconstruction and relocation of CR 83 and CSAH 16 which have involved regrading portions of the VGCC site. (Note to reviewers: Please note that as of May 2003, this work has been completed.) 1. The construction to meet the revised concept plan will require preparation, submission and approval by appropriate agencies of a new grading plan, prior to construction. Utility and street construction will complete the improvements associated with the VGCC development and individual parcels within this site will be made available for sale. Purchasers must then submit appropriate building and site designs, to all appropriate agencies, that demonstrate compliance with all codes and regulations. Option B a. The business park will contain a mix of approximately 1,300,000 sf of office, warehouse, and light industrial sites located adjacent to TH169 on 91 acres as shown in FIGURE 4. b. The residential portion of the project will consist of medium-density residential with approximately 364 attached owner-occupied townhome units and 20 I unattached townhome units on 80 acres of the site. Housing types are anticipated to include: . Townhouses designed for a neighborhood appearance with front stoops facing the streets and vehicular access in the rear of the units. . Three level townhouses that offer generous living areas c. Subsequent to the July, 2000 AUAR, the City employed the services of Brauer & Associates to assist in overall planning activities which included the West Dean's Lake Area. Documentation of the conclusions reached in these endeavors is included in the APPENDIX C and D. A full copy of the Dean's Lake Area Parks, Open Space, and Trails Master Plan is available upon request. Ryan Companies, who have assumed the role of primary developer of the property participated in these planning efforts. City of Shakopee Valley Green Corporate Center 2003 AUAR Page - 5 d. Option B includes more medium density residential housing and less business park than Option A (July 2002 AUAR). The following features which were included as part of Option A are also included with Option B. . . Option B includes construction of storm water management areas throughout the site as proposed as part of Option A. . Rainfalls that exceed the capacity of these areas to store and infiltrate will overflow and be directed to the K-Mart Linear Pond on the north side of US 169. The City designed and constructed this pond to accommodate the VGCC area and areas further south. . The Natural Space Conservation Areas proposed as part of Option A are also included aspart of Option B and will provide a trail corridor, park, and conservation areas. This area is approximately 94 acres. . The business park located adjacent to TH169 and County Road 83 will be used for commercial functions, mixed office, warehouse, light industrial, and smaller retail/restaurant. e. The site will be served by public water with approval from Shakopee Public Utilities Commission. Wastewater generated on-site will be treated at the Metropolitan Council-Environmental Services Division Blue Lake Wastewater Treatment Facility. f. Roadways associated with the development will be completed by the developer and be in conformance with City design standards. Since the July 2002 AUAR, improvements to CR83 and CSAH 16 have been completed. g. Phasing of development will start with the utility and street construction. Once this is complete, purchasers will submit building and site design plans for approval by the appropriate agencies. Development associated with this site will need to be in conformance with this AUAR, applicable Federal and State regulations, and City Standards for either option.

Describe current and recent past land use and development on the site and on adjacent lands. Discuss project compatibility with adjacent and nearby land uses. Indicate whether any potential conflicts involve environmental matters. Identify any potential environmental hazards due to past site uses, such as soil contamination or abandoned storage tanks, or proximity to nearby hazardous liquid or gas pipelines. Option A and B (Information obtained from the Julv 2000 AUAR, aerial photograph review, and information from the site plans) The project area currently consists of dormant farmland, wooded areas, and wetland. The site is surrounded by TH169 to the north, CSAH 83 to the west, CSAH 16 to the south, Dean's Lake and single family homes to the south, and undeveloped wetlands associated with Dean's Lake to the east. The Southbridge residential development is north and west of Dean's Lake. Property north ofTH169 hasbeen developed for commercial uses. The land south ofCSAH 16 is owned by the Mdewakanton Sioux Community. The site's recent history includes a majority of the property being rough graded in anticipation of the previously approved preliminary plat for the VGCC development. The site currently is used in agricultural production. Information from the MPCA found no environmentally contaminated sites within the project area. The City's current zoning plan identifies the area as BP (Business Park) and Bl (Highway Business) as shown on FIGURE 5. FIGURES 6 and 7 show the 1999 and 2000 aerial photos for the site. The proposed medium- density residential and business park is consistent with adjacent parcels. Option B proposes more residential and less commercial than Option A as shown on FIGURES 3a and 4. However, the land use plan will need to be re-guided and re-zoned to accommodate this development. A natural conservation area with a trail system is proposed to provide a natural buffer around Dean's Lake and allow residents to interact with the environment. 10. COVER TYPES 10. Cover Types. The following information should be provided instead: a. cover type map, at least at the scale of a USGS topographic map, depicting: City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 9 I -wetlands- identified by type (Circular 39) -watercourses- rivers, streams, creeks, ditches -lakes- identify protected waters status, and shoreland management classification -woodlands- breakdown by classes where possible -grassland- identify native and oldfield -cropland -current development b. an "overlay" map showing anticipated development in relation to the cover types; this map should also depict any ''protection areas, " existing or proposed, that will preserve sensitive cover types. Separate maps for each major development scenario should generally be provided. Option A and B (Information from the 2000 AUAR and information from the site plans) FIGURES 6 and 7 show the aerial photos from 1999 and 2000. FIGURE 8 shows the current cover types on the site. In the past, portions of the VGCC were covered with oak savannah. FIGURE 3a shows the site plan for Option A and FIGURE 4 shows the site plan for Option B. The site was rough graded approximately three years ago in anticipation of the previously approved preliminary plat. Several factors were involved in the initial grading of the Valley Green Corporate Center site and the removal of the trees: . Tree Removal: The VGCC site was specifically identified in the City's Oak Wilt suppression program as a "Large Oak Wilt Infection Center within Shakopee". As such, certain mitigation measures were performed which removed a portion of the trees. . In addition, a portion of the trees were destroyed by storm damage. Since it will be the responsibility of individual lot owners to propose specific building and landscaping plans for each developed lot, it is beyond the scope of this AUAR to precisely "predict" cover types to be used. Estimates of cover types was not available for Option A.

FISH, WilDLIFE AND ECOLOGICAllY SENSITIVE RESOURCES 11. Fish, Wildlife, and Ecologically Sensitive Resources. a. The description of wildlife and fish resources should be related to the habitat types depicted on the cover types maps (of item 10). Any differences in impacts between development scenarios shouldbe highlighted in the discussion. O{>tion A and B (Information from the 2000 AUAR) The project site overlaps a portion ofland known as the West Dean's Lake Area. The West Dean's Lake Area consists of woodland, open space, Dean's Lake and a complex of wetlands and marshes. Fisheries There are no DNR fishery surveys recorded within this project's boundaries. The adjacent Dean's Lake is a DNR Public Water (Identification 70-0074) and classified as a Type 4 wetland with an average depth 00 feet and a maximum depth of 5 feet. Stocking of the lake is limited due to the threat of winter kill. There is the possibility of fish entering Dean's Lake from Prior Lake, Pike Lake; or Spring Lake through an overflow channel. However, this would generally only occur during a high water event. If the high water event coincided with the spawning season, fish could migrate to the wetlands (Daryl Ellison, MDNR - West Metro Fisheries, by phone conservation and email, Feb. 14.2000). Although, individuals may have experienced satisfactory fishing in Dean's Lake, "... The low water level in Dean's Lake, coupled with the significant natural accumulation of organic sediment would likely cause winter kill of fish, except for the possible survival of rough fish that are tolerant to very low dissolved oxygen levels" (April 24, 2000 memo to the City froIIlSteven Carlson, STS Consultants). The introduction of higher quality fish life to Dean's Lake is primarily through overflow from Spring Lake, Prior Lake, and/or Pike Lake through the overflow channel and in warmer winters, there may be some survival (email dated June 2, 2000 from Steven Carlson, STS Consultants, to Del Jackman, Bolton Menk). Although no direct waterway connection is identified, fish migration toward Dean's Lake could occur during periods of high flow in the Prior Lake/ Spring Lake outlet channel. Winter kill during most years prevents the development of a permanent, self sustaining fishery in Dean's Lake (Daryll Ellison, MDNR - West Metro Area Fisheries, by phone conversation! E-mail with Ross Knapper, Feb. 14.2000 and Del Jackman, Bolton and Menk, June 22, 2000.) Wildlife The west portion of the proposed development is grassland that has been converted to agricultural land in past years. The land around Dean's Lake contains a diverse mix of habitats and natural resources. Three principal cover types are predominant in making up the area: wetland, woodland, and grassland. Refer to FIGURE 8. It is expected that wildlife species known to exist locally could populate or migrate through the project site. The most common are: deer, coyote, turkeys, rabbits, squirrels, raccoons, muskrats, pheasants, ducks, and geese. Other non-game species such as hawks and other rap tors do migrate through the property. A thorough biological survey has never been performed for the project site. According to Diana Regenscheid, MDNR- Division of Wildlife, there have been a few unconfmned cougar sightings in the vicinity, but stated that this would be "highly unusual andunlikely." City of Shako pee Valley Green Corporate Center 2003 AUAR Page-II ; According to Ms. Regenscheid, development of the property will more than likely have some effect on the present wildlife. The increase presence of human activity may displace some species or limit wildlife use of the site. As it exists, the habitat would support wildlife populations through a variety of life cycle needs. There is the possibility that some of these needs may not be met in the specific project site following development (Phone conversation with Diana Regenscheid, MDNR- Wildlife Division, by phone conversation and email with Ross Knapper, Feb. 14,2000). In order to minimize and lessen the possible displacement of wildlife from the project site, efforts should be made to avoid negative impacts to wildlife. Where impacts are unavoidable, appropriate mitigation efforts should be implemented. These mitigation efforts currently consist of re-vegetation of disturbed soils with a mix of native flora, protection of several existing stands of trees, construction of a 1.2 acre wetland, delineation of a "no impact zone" around Dean's Lake, as well as maintaining proper building setbacks. b. For an A UAR, prior consultation with the DNR Natural Heritage program for information about reports of rare plant and animal species in the vicinity is required. If such consultation indicates the need, an on-site halJitat survey for rare species in the appropriate portions of the AUAR area is required. Areas of on- site surveys should be depicted on a map, as should any ''protection zones" established as a result. Option Aand B (Information from the 2000 AUAR with minor updates) Extensive studies and reviews have been conducted by the DNR as part of the County Biological Survey and Woods End Landscaping, a specialist in native plant "rescue" and transplanting. The DNR report concluded that "no rare species or Natural Plant Communities" were identified on the Business Park site and "According . to the review conducted by Mr. Nelson[sic - of Woods End Landscaping}, the native plants were not rare enough to warrant heroic efforts to protect... " (Steven Carlson, STS Consultants, email to Del Jackman, Bolton and Menk, May 31, 2000). Although the Minnesota Rules which govern activities relating to species of special concern states that, "Species designated as species of special concern are not protected by Minnesota Statutes, section 84.0895 or rules adopted under that section ....Parts 6134.0100 to 6134.0400 do not address protection of habitat for species . designated as endangered, threatened, or species of special concern, nor do they obligate anyone to survey lands for the presence of designated species" (Minnesota Rules 6134.0150), an information request was submitted to the Minnesota DNR's Natural Heritage and Nongame Research Program (APPENDIX F) to identify all known locations of rare, threatened and endangered species in the vicinity of the project. The inquiry determined that the following rare, threatened and endangered species are possibly located within a one-mile radius of the project site.: . Bald Eagle (Haliaeetus leucocuphalus): The Bald Eagle is considered a special concern species in the State of Minnesota and labeled "threatened" by the federal government. Bald Eagles have been spotted north of the project site within a National Wildlife Refuge. Bald Eagles have not been spotted within the project boundaries and thus will not be directly affected by the proposed development. . Hill's Thistle (Cirsium hillii): Hill's Thistle is considered a special concern in the State of Minnesota and was found in Section 5 of Scott County. Hill's Thistle has not been spotted within the project boundaries and thus will not be directly affected by the proposed development. . Dry Prairie (Southeast) Barrens Subtype: A barrens prairie is located east of the proposed development. The dry prairie is a natural community consisting of sparsely vegetated grasslands, with often-exposed patches of bare soil. It is given a state rank of 1, meaning it is considered in greatest need for conservation action. The barren subtype of the dry prairie occurs only on sand dunes of the Anoka sandplain, and are considered the most distinctive but also the least common ofthe Region's dry prairies. Rare animals commonly found in barren prairies include the Plains Pocket Mouse and the Western Hognose Snake. The project site does not contain identified dry City of Shako pee Valley Green Corporate Center 2003 AUAR Page -12 I prairies. The dry prairie located to the east of the project site is not anticipated to be directly affected by the proposed development. . Rhombic-Petaled Evening Primrose (Oenothera rhombipetala): Rhombic-Petaled Evening Primrose is considered a special concern species in the State of Minnesota. It is a large, conspicuous biennial of sandy habitats. Rhombic-Petaled Evening Primrose was found to the east of the project site. Rhombic-Petaled Evening Primrose has not been spotted within the project boundaries and thus will not be directly affected by the proposed development. In addition, mitigation measures within the project site currently include the re-vegetation of the replacement wetland and buffer areas with several native species including Rhombic-Petaled Evening Primrose. . Plains Pocket Mouse (Perognathus flavescens): The Plains Pocket Mouse is considered a special concern in the State of Minnesota. This small, long-tailed mouse typically occupies arid to semi- arid habitats and feeds on the seeds of prairie plants (Coffm and Pfannmuller, 1988). The Plains Pocket Mouse was found to the east of the project area and has not been spotted within the project boundaries. Thus it will not be directly affected by the proposed development. . Gopher Snake (Pituophis melanoleucus): The gopher or bull snake is considered a special concern species in the State of Minnesota. This snake prefers sandy soils, dry prairies, oak savannas, and pine barrens (Coffm and Pfannmuller, 1988). Evidence of this species was found to the east of the project area. The Gopher Snake has not been spotted within the project boundaries and thus will not be directly affected by the project development. The land to the north and west of Dean's Lake is considered a mixed emergent marsh and labeled as a natural community, although no record occurs in the Natural Heritage Program database. No rare species are known to inhabit this natural community occurrence. However, natural communities are considered rare features themselves. A mixed emergent fact sheet provided by the DNR's Natural Heritage Program can be found in APPENDIX F. Plans for the proposed development include a "no impact zone" around Dean's Lake and minimum building setback distances set the City of Shako pee zoning ordinances to prevent any negative impacts to the shoreland of Dean's Lake. Additional mitigation measures have been described in the Water Resource and Water Quality sections of this report. Additional Information and Analysis Provided for the 2003 AUAR The MnDNR was contacted again in the spring of2003; a database check of the project area indicated the same six species identified in the original search. The impact of development Option A and B on wildlife in the area will be similar. Both developments include the conversion of open space to developed space. For wildlife that cannot adapt to urban settings, displacement will occur as the amount of habitat available will be reduced. While Option A ~ will generally create more impervious surface, Option B will cause more people to be in the area with the additional medium density housing. However, both options include the same setback and conservations areas that were proposed in the 2002 AUAR. This natural open space will provide a trail corridor, park, conservation areas and ecologically based storm water management system while preserving wetlands, wooded areas, and shoreland areas. The buffer areas created by the 250' setback from Dean's Lake will preserve an area of habitat within the site for wildlife. This natural open space has been included in both Option A and B in conformance with the Dean's Lake Area Park, Open Space, and Master Trail Plan--as well as the Community Value Statement for the Valley Green Development-West Dean's Lake. 12. PHYSICAL IMPACTS ON WATER RESOURCES City of Shako pee Valley Green Corporate Center 2003 AUAR Page-I3 f 12. Physical Impacts on Water Resources. The information called for on the EA W form should be supplied for any of the infrastructure associated with the A UAR development scenarios, and for any residential or commercial development expected to physically impact any water resources. Where it is uncertain whether water resources will be impacted depending on the exact design of future development, the A UAR should cover the possible impacts through ,a "worst case scenario'" or else prevent impacts through the provisions of the mitigation plan. Option A and B (Information from the 2002 AUAR -the proposed wetland impact and miti2ation is the same for both Options) The original development plan in the 2000 AUAR included the filling and corresponding mitigation of 0.52 acres of wetlands. The construction and re-vegetation of 1.2 acres of wetland and an associated 1.7 acres of buffer has been completed. The area is developing the anticipated wetland characteristics. The site plan for the Option A and B requires filling four additional wetland areas covering a total area of 1.29 acres. The impacted wetlands are shown on FIGURE 9 (Option A) and FIGURE 10 (Option B) and summarized in TABLE 12-1a. The following is a summary of the Wetland Delineation and Wetland Permit 1 Documents (permit documents are available for the previously mitigated wetlands). At this time, no permits have been prepared for the wetland areas to be mitigated for Option A or B. A full copy of the Wetland Delineation and Previous Wetland Permit Document is available upon request. This report indicates that removal of these wetlands is necessary to maintain setbacks as required by local zoning and comply with design lines, as well as conforming with safe roadway design practices for the streets and to accommodate the development of the Center. The replacement wetland area will be immediately adjacent to the existing wetland area on the north side of Dean's Lake. This expansion of existing wetland areas. offers the assurance of the necessary hydrology to feed and maintain the vegetation within the replacement wetland. This replacement wetland will be immediately available to wildlife in the vicinity.

Total 1.29 Mitigation for the loss of the impacted wetlands will be done on-site. Plans include the construction of a 2.58- acre replacement wetland. The areas designated for wetland replacement are adjacent to the Dean's Lake wetland areas, near US 169, as shown on FIGURES 9 and 10. By expanding the existing wetland area, there should be minimal acclamation required for the new wetland habitat. To date, no Wetland Permit documents have been submitted for Options A or B. The Wetland Permit Documents, when submitted shall detail the sequence of construction, address the ordinary high water (OHW) mark for Dean's Lake (747 Mean Sea Level-MSL), and shall comply with the City of Shakopee grading standards to a design level of748.6 MSL. The previous grading plans also call for a variety of substrate 1 STS Consultants Ltd. 1999. Wetland Delineation and Wetland Permit Documents.

Slopes will be designed to maximize mitigation efforts. Erosion control will follow applicable Best Management PractIces (BMP's) as appropriate for soils rated with a 'severe' potential for erosion.2 The Wetland Mitigation Plan shall indicate that BMP's to be used will include traffic control, erosion control, temporary construction protection, and restoration seeding. Final phases of construction will include top dressing and re-vegetation of the replacement wetland, buffer areas, and all other disturbed soils.

The answer to this question would appear to be no. A study by Lower Minnesota River Watershed District engineer Lawrence Samstad (1975) on the source of water for Dean's Lake and related issues found that Dean'sLake is not hydraulically isolated from the surficial sand aquifer by tight sediments forming a "seal"; rather, the level of Dean's Lake directly reflects ambient groundwater levels.. This finding is consistent with two MnDNR studies that focused on the potential for quarry dewatering effects on Dean's Lake (Beissel and Ford, 1981; Drivas, 1997). In any case, the site grading is well separated from Dean's Lake and the adjace~t wetland. The possibility of disturbing such a "seal" even if it existed would be minimal and would not have an impact. 3 13. WATER USE 13. Water Use. With respect to band c, if the area requires new water supply wells specific information about that appropriation and its potential impacts on groundwater levels should be given; if groundwater levels would be affected, any impacts resulting on other resources should be addressed. With respect to possible individual appropriations by future projects, a general assessment of the likely need for such should be included, and if there is potential for major appropriations or environmental issues assessment of those should be included along with a discussion of mitigation for potential problems. Option A and B Gnformation generally from the 2000 AUAR) a. Will the project involve the installation or abandonment of any wells?' DYes 18/ No For abandoned wells give the location and the Unique well number. For new wells, or other previously unpermitted wells, give the location and purpose of the well and the Unique well number (if known). There are no wells known to exist within the project limits of the site. However, if any are discovered in the course of the construction, they will be sealed in accordance with all local, State, and Federal regulations. b. Will the project require an appropriation of ground or surface water (including dewatering)? 18/ Yes DNo If yes, indicate the source, quantity, duration, purpose of the appropriation, and DNR water appropriation permit number of any existing appropriation. Discuss the impact of the appropriation on ground water levels. For both Option A and B, the proposed development may, depending on site conditions and time of year, require a temporary permit for construction dewatering purposes. Dewatering may be necessary to accommodate construction of the required infrastructure. Cessation of dewatering will occur once construction has been completed. c. Will the project require connection to a public water supply? 18/ Yes D No If yes, identify the supply, the DNR water appropriation permit number of the supply, and the quantity to be used. Both Option A and B would acquire its water supply from the City of Shakopee Public Utilities Commission (MnDNR Appropriation Permit Number 806205). In September 1999, the City of Shakopee received approval for its Metropolitan Urban Service Area (MUSA) amendment involving the addition of 554 acres to the MUSA. These 554 acres of expansion included two areas - a 222-acre property guided for commercial development located south of CSAH 16 on both sides of CSAH 18 and a 332-acre property guided for business park located south ofTH169 between Dean's Lake and CSAH 83 (VGCe). The approval for the expansion was evaluated by 3 Erdmann, John, Wenck Associates City of Shako pee Valley Green Corporate Center 2003 AUAR Page -16 i comparing future water demands with current demand. It was estimated that the new MUSA expansion would require 660,000 gallons per day (gpd) (source: Schoell and Madson July 1999, "Comprehensive Water Plan, 1999 Supplement" prepared for the City of Shakopee). This approval was reviewed and passed by the Metropolitan Council in September 1999 and was contingent upon the Shakopee Public Utilities Commission's (SPUC) ability to supply sufficient water to the expansion areas. It should be noted that since the 2000 AUAR, SPUC has created additional wells in the area to supply the City of Shakopee. Therefore, the conditions of the Met Council approval have been met. Option A (New analysis) Of the 554 acres considered in the MUSA expansion, the VGCC encompasses 265 acres (48%) of this area. Since 660,000 GPD was the estimated demand for the new MUSA area, 48% of this is 316,800 GPD. The actual estimated water demand to supply the proposed site is 2l7,692GPD (see equation below).

Locations of the utilities are shown on FIGURE 11a and 11b. Option B (New information) Of the 554 acres considered in the MUSA expansion, the VGCC encompasses 265 acres (48%) of this area. Since 660,000 GPD was the estimated demand for the newMUSA area, 48% of this is 316,800 GPD. The actual estimated water demand to supply the proposed site is 245,810 GPD (see equation below). (0.07 GPD/SF x 1 ,300,000sf commercial) + (565 units x 274 GPD residential)==245,81 0 Connection will be made to the City's public water supply via a 12-inch watermain. Locations of the utilities are shown on FIGURE 12. This utility plan shows only major connection points and a more detailed design would be completed in the future to meet City Standards. 14. WATER RELATED LAND USE MANAGEMENT DISTRICTS 14. Water-related Land Use Management Districts. Such districts should be delineated on appropriate maps and the land use restrictions applicable in those districts should be described. If any variances or deviations from these restrictions within the AUAR area are envisioned, this should be discussed. Option A (Information from the 2000 AUAR with some additional or updated information ) No formal "water use management district" exists in the area, however, the City's Shoreland Control Ordinance does establish restrictions on the use of the property adjacent to public waters (Dean's Lake). Dean's Lake is classified as a Natural Environment Lake. The ordinance establishes a 200' setback from the ordinary high water (OHW) for multiple family residential developments and a 100' no vegetation clearing zone. The ordinance also provides for doubling the distances for non-water related uses. In addition, the provisions of the City Shoreland zoning ordinance state, "...[sic-buildings] iflocated on lots or parcels with public water frontage, must either be set back double the normal ordinary high water level setback or be substantially screened from view from the water by vegetation or topography, assuming summer, leaf-on conditions." Therefore, individual building designers would have the option of constructing appropriate screening City of Shako pee Valley Green Corporate Center 2003 AUAR Page -17 , rather than meeting the increased setbacks. This discussion is beyond the scope of this AUAR since it applies to the individual building owners. A proposed grading plan was submitted to the City for review and approval in 1999. At that time, the plan included a 75-foot no impact zone around the lake shoreline which met the City's Shoreland Ordinance for water related uses. Since the 1999 grading plan submittal, a more detailed concept plan was developed (Option A) that included a 250' setback with a trail as shown on FIGURE 3a. This 250' setback is in conformance with the recommendations outlined in the Dean's Lake Area Park, Open Space, and Master Trail Plan. Individual site plans are beyond the scope of this AUAR, but it is required that all future site activities including building permit requests be specifically reviewed for compliance with all applicable regulations, including the Shoreland Ordinance and include doubling the setback distance or providing appropriate screening. Option B (New information) The City's Shoreland Ordinance applies to Option B in the same way it applies to Option A. A 200' setback is required for multiple family residential developments and a 100' no vegetation clearing zone also must be implemented. The ordinance also provides for doubling the distances for non-water related uses. Option B provides the same 250' setback as recommended by the Dean's Lake Area Park, Open Space, and Master Trail Plan. The setback and buffer encompass approximately 94 acres of the site and will contain a trail, park, and natural open space. FIGURE 4 and 12 show the appropriate setbacks for the proposed development. Individual site plans are not available as part of this AUAR, but it is required that all future site activities including building permit requests be specifically reviewed for compliance with all applicable regulations, including the Shoreland Ordinance and include doubling the setback distance or providing appropriate screening. 15. WATER SURFACE USE 15. Water Surface Use. This item need only be addressed if the AUAR area would include or adjoin recreational water bodies. Option A and B (Includes modified text from 2000 AUAR) Neither Option A nor B contain any recreational water bodies. However, Dean's Lake is a public water adjacent to the project area. Dean's Lake is shallow, classified as a "Natural Environment" lake, and is suitable for passive recreational purposes, although fishing and non-motorized boating is known to occur on the lake. No legal access to Dean's Lake has been eliminated or is proposed as part of either Option A or B. Access to the lake will continue as it has in the past. Question 14 contains additional information about the setbacks and buffer areas. 16. EROSION AND SEDIMENTATION 16. Erosion and Sedimentation. The number of acres to be graded and number of cubic yards of soil to be moved need not be given; instead, a general discussion of the likely earthmoving needs for development of the area should be given, with an emphasis on unusual or problem areas. In discussing mitigation measures, both the standard requirements of the local ordinances and special measures that would be added for A UAR purposes should be included. Option A and B (Information from the 2000 AUAR some modifications and additions) Question # 19 and FIGURE 13 contain information from the Scott County Soil Survey for the sites. City of Shako pee Valley Green Corporate Center 2003 AUAR Page -18 I The pre-2000 Valley Green site plan included the filling and proposed mitigation of 0.52 acres of wetland using an on-site location for the replacement. This mitigation has been achieved and the replacement wetland area is assuming the characteristics of a sustainable wetland. The design for Option A and B will require some adjustment to the site grading which had been nearly completed. This adjustment will include the filling of an additional 1.29 acres of wetland, (FIGURE 9 and 10), which will be mitigated with on-site replacement in a manner similar to the previous 0.52 acres. The construction of this replacement wetland includes the excavation and grading to achieve proper design elevation and slope gradients. Steep slopes are present on the site in the area adjacent to CSAH 16. In this area, the site layout for Option A and B has been designed to minimize disturbances to the steep slopes. During all construction phases of Option A or B, erosion control will continue to follow the applicable Best Management Practices (BMP's) to minimize the effects of erosion and sedimentation on Dean's Lake and all wetland areas. BMP's utilized will include but are not limited to erosion control blankets, silt fences, and staked hay bales. The particular BMP's chosen should acknowledge that the soils covering most all the site are categorized as 'severe' for erodability in cuts and fills, and BMP's to mitigate thisimpaGt must be enforced. However, wind erosion on previously cultivated areas will likely decrease with the introduction of year-round ground cover (pavements, buildings, lawns, native grasses and wetlands). Following completion of grading and construction all disturbed soils should bere-vegetated to prevent future wind erosion. Wind erosion within the subject area of this AUAR will likely decrease when fully developed with the introduction of year-round ground cover (pavements, buildings, lawns, native grasses and wetlands). The areas where vegetation has been stripped will be revegetated as a part of the next stage of the development, as individual building owners present and implement their plans. Options A and B are subject to. the City's Erosion Control Ordinance. This ordinance requires the development to incorporate BMP's to reduce soil loss and erosion, exposure of soil must be minimized to the greatest extent practical, within 30 days of rough grading, the site must be seeded and mulched, and natural vegetation and plant cover must be maintained whenever possible. No exposed slopes should be steeper in grade than 3 feet horizontal to 1 foot vertical. Additionally, this development is required to comply with the National Pollutant Discharge Elimination System (NPDES) Stormwater Permit administered by the MPCA. 17. WATER QUALITY - SURFACE WATER RUNOFF 17. Water Quality - Surface Water Runoff For an AUAR the following additional guidance should befollowed in addition to that in ilEA W Guidelines ": - it is expected that an A UAR will have a detailed analysis of storm water issues,. - a map of the proposed storm water management system and of the water bodies that will receive storm water should be provided,. - the description of the storm water systems would identify on-site and "regional II detention ponding and also indicate whether the various ponds will be new water bodies or converted existing ponds or wetlands. Where on- site ponds will be used but have not yet been designed, the discussion should indicate the design standards that will be followed. - if present in or adjoining the A UAR area, the following types of water bodies must be given special analyses: - lakes: within the Twin Cities metro area a nutrient budget analysis must be prepared for any "priority lake II identified by the Metropolitan Council (see Appendix E of ilEA W Guidelines 11 (1990) or contact the Council staff). Outside of the metro area, lakes needing a nutrient budget analysis must be determined by consultation with the MPCA and DNR stafft,. - trout streams: if storm water discharges will enter or affect a trout stream an evaluation of the impacts on the chemical composition and temperature regime of the stream and the consequent impacts on the trout population (and other species of concern) must be included. City of Shako pee Valley Green Corporate Center 2003 AUAR Page -19 I O{ltion A and B (Information from the 2002 AUAR with some minor additions for Option ill The storm water management plan for Option A is shown on FIGURE 14. The storm water management plan for Option B is shown on FIGURE 15. Land development changes the quantities of nutrients, sediments, and other pollutants carried away from the site by runoff. Many factors contribute to the changes including the reduction in use of agricultural herbicides, pesticides and fertilizers; the introduction of year round ground cover; the enhanced conveyance ofleaf-fall, grass clippings, pet litter, other litter of both natural and human origin; and pollutants from the atmosphere (both "wetfall" and "dryfall"); lawn fertilizer use; vehicle emissions and mechanical wear; sanding and salting of streets and sidewalks. Therefore, "BMP's" should be utilized to mitigate pollutant loadings entering Dean's Lake. The concept plan for Options A and B illustrated in FIGURE 3a and FIGURE 4,respectively, and described in the Community Value Statementfor Valley Green Development, West Dean's lake Area 4 (see the APPENDIX C}proposes a concept for the plantings which could significantly decrease the potential for adverse environmental impacts. Previously, significant portions of the site would have been planted with boulevard sod, which could require regular use of lawn fertilizers. The revised concept is to designate large portions as 'Natural Open Space Consetvation Area', including placing easement restrictions on them which permit the City to enforce natural plantings with more restrictive use offertilizers. In addition, the State of Minnesota has enacted legislation which will eliminate the use of phosphorous in the Metro area. 5 The Valley Green site lies across the dividing line between two very large watersheds as shown on FIGURE 16 and 17. The direct Dean's Lake watershed is approximately 6,900 acres in size, with only 117 acres coming from . VGCC. Prior to site grading, the total contributing area from the site was approximately 129 acres. In addition, during periods of high rainfall the overflow outlet for Prior Lake, Pike Lake and Spring Lake drain through Dean's Lake, which brings the total to over 9,600 acres, plus the area of Prior Lake, itself. The westerly and southerly portions of the site (generally, south of CSAH 16) are tributary to the K-Mart linear detention pond on the north side of US 169, where the runoffhas the opportunity for sedimentation to take place. Approximately 12 acres of storm water runoff will be diverted directly to the K-mart linear pond on the north side of US 169. The portion of the VGBP which was tributary to Dean's Lake before site grading was 129.5 acres and the portion that remains tributary is 117.6 acres. The boundaries of these drainage areas are shown on FIGURE 18. FIGURE 17 illustrates the planning boundary used in the Comprehensive Stormwater Management Plan (CSMP) for the tributary area flowing toward Dean's Lake. The diagram shows this tributary area extending northward, to the right-of-way line of US 169. In 1999, as part of the response to a request for an environmental review, FIGURE 18 was prepared showing a pre- 1999 divide in flow toward Dean's Lake which does not reach the right-of-way line of US 169. Presumably, this figure was prepared to evaluate the specifics of the preliminary grading which had been performed, and not as an overall drainage evaluation to determine the health of Dean's Lake. That review was included in FIGURE 17, where it was decided to restrict the incoming rate of flow to 0.1 cubic foot per second (cfs) per acre. Apparently, the flora around the Dean's Lake water body is not particularly sensitive as evidenced by 10 years of obsetvations by STS, "During the re-flagging of the wetland boundary, STS encountered remnants of flagging placed during previous delineations, suggesting that the wetland plant community had not changed sufficiently to alter the jurisdictional boundary. Some trees had been impacted by Oak Wilt spread and storm damage, but 6 alteration of the plant community was not obsetved." The storm water management plan concepts for the two options are the same. The storm water management plan uses storm water infiltration areas (Option A - FIGURE 14; OptionB - FIGURE 15) and regrading of portions of the site will be necessary. These changes will eliminate the on-site detention pond concept in favor of promoting the infiltration of storm water. Stormwater runoff in excess of the infiltration capacity will be directed to the existing K- 4 Bauer & Associates, Ltd., Community Value Statement/or Valley Green Development. West Dean's lake Area, Nov., 2001. 5 Minnesota Department of Agriculture Press Release, April 19, 2002, as available on the Internet at - hrtp://www.mda.state.mn.us/newsreleases/2002news/apr 19 Ol.htm 6 - Carlson, Steven J., STS Consultants, Ltd., e-mail to Del Jackman, Bolton & Menk, Inc., May 31,2000, page 3. City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 20 I . Mart Linear Pond on the north side of US 169. Discharge from the site will be limited to oJ cfs per acre established in the AUAR dated July 2000 and required by the City. In general, Option B will have less impervious surface overall than Option A, thus generating less overall runoff. The infiltration and storm water management areas for either option will be designed in conformance with City Standards and the mitigation plan outlined in this AUAR. A "Comprehensive Stormwater Management Plan" was completed for the City of Shakopee in 1999 (WSB & Associates); and subsequently adopted. The Plan includes the following standards: . All new stormwater systems should comply with the City's Comprehensive Stormwater Management Plan and provide runofftreatrnent to NURP (National Urban Runoff Program) standards prior to discharge. NURP standards include: . Permanent pool volume equal to runoff from the pond's drainage area from a 2.5..:inch storm, plus an allowance for sedimentation; and . Permanent pool mean depth of at least 4 feet but less than 10 feet. . New pond outlets must have oil skimmers that extend at least 4 inches below the water surface and that limit water velocity below the skimmer to less than 0.5 foot per second for moderate storms (I-year return interval). New ponds in the Dean's Lake drainage area must limit the peak discharge rate to a maximum of 0.1 cfs (cubic feet per second) per acre in a 100-year storm and, as feasible, to 0.05 cfs per acre in a 10-year storm. (These requirements are primarily for flood-control, but they also enhance water quality because discharge rate limitations increase detention time and enhance particulate solids settling.) During the development of the City of Shakopee' s Comprehensive Stormwater Management Plan; the entire study area was analyzed. The study investigated the fully developed condition of the watershed, which is intended to be developed into a commercial or industrial land uses. Underthe fully-developed condition, the flow at the Trunk Highway 101 culvert is anticipated to be 760 cfs. The City and Prior Lake/Spring Lake Watershed District are currently undertaking a hydrologic study of the Deans Lake/Prior Lake outlet channel to verify the hydraulic capacity of this channel, and to recommend changes if necessary. The City's plan also calls for conformance with (1) the Metropolitan Council's Interim Strategy to Reduce Nonpoint Source Pollution to All Metropolitan Water Bodies (Frost and Schwanke, 1999), (2) BMPs for urban areas as . recommended by the Minnesota Pollution Control Agency (1989), and (3) revised Shoreland Ordinance provisions following MDNR directives. 7 Adherence to the City's Comprehensive Stormwater Management Plan, especially the ponding requirements, is required to mitigate the greater part of any contaminant from the developed site. b. Identify the routers) and receiving water bodiesfor runofffrom the site. Estimate the impact of the runoffon the quality of the receiving waters. (If the runoffmay affect a lake consult "EAW Guidelines" about whether a nutrient budget analysis is needed). Option A and B (Information developed from past AUAR and the site plans) The majority of the site presently drains to the north, with the easterly edge of the development closely following the drainage divide for Dean's Lake, as identified in the City of Shako pee's 1999 Comprehensive Stormwater Management Plan. Discharge from the project will be limited to the criteria for water quality and quantity as identified in the City's Stormwater Plan. 7 Erdmann, John, Wenck Associates. City of Shakopee Valley Green Corporate Center 2003 AUAR Page - 21 I The proposed design will be consistent with the City's Stormwater Management Plan and maintain the existing drainage divides. A stormwater infiltration system and on-site stormwater ponding, with adequate dead storage and skimming, will be implemented throughout the site to reduce non-point source pollution through implementation of Best Management Practices. Rate control and water quality will be provided prior to discharging into off-site receiving water bodies. FIGURE 14 (Option A) and FIGURE 15 (Option B) show the preliminary storm sewer design. A network of infiltration basins and ponds are proposed as part of the stormwatermanagement system. Ponds constructed at lower elevations are designated for lining, to limit the infiltration rate and thus offer some level of protection to ground water. Ponds constructed at higher elevations (along the existing CSAH 16) are proposed to be 'dry' and not lined in order to promote feeding the ground water system. This system of infiltration basins, ponds, and constructed wetlands ultimately discharge into the Prior Lake's outlet channel, a ditch that leads from Dean's Lake north to the Minnesota River. The project does not contain any identified trout streams nor will storm water be discharged into any identified trout stream. Additionally, Dean's Lake is not considered a "priority lake" and thus does not require a nutrient budget. 18. WATER QUALITY - WASTEWATER 18. Water Quality - Wastewater. Observe the following points of guidance in an A UAR: . only domestic wastewater should be considered in an AUAR---industrial wastewater would be coming from industrial uses that are excluded from review through an A UAR process; . wastewater flows should be estimated by land use subareas of the AUAR area; the basis offlow estimates should be explained; . the major sewer system features should be shown on a map and the expected flows should be identified; . if not explained under item 6, the expected staging of the sewer system construction should be described; . the relationship of the sewer system extension to the RGU's comprehensive sewer plan and (for metro area A UARs) to Metropolitan Council regional systems plans, including MUSA expansions, should be discussed. For non-metro area A UARs, the AUAR must discuss the capacity of the RGU's wastewater treatment system compared to the flows from the A UAR area; any necessary improvements should be described; . if on-site systems will serve part of the A UARthe guidance in "EA W Guidelines" (pages 16-17) should be followed. a. Describe sources, quantities~ and composition (except for normal domestic sewage) of all sanitary and industrial wastewaters produced or treated at the site. b. Describe any waste treatment methods to be used and give estimates of composition after treatment, or if the project involves on-site sewage systems, discuss the suitability of the site conditions for such systems. Identify receiving waters (including ground water) and estimate the impact of the discharge on the quality of the receiving waters. (If the discharge may affect a lake consult "EAW Guidelines" about whether a nutrient budget analysis is needed). c. Ifwastes will be discharged into a sewer system or pretreatment system, identify the system and discuss the . ability of the system to accept the volume and composition of the wastes. Identify any improvements which will be necessary. Option A (Information from the 2000 AUAR and new information) Option A includes approximately 2,100,000 sf of comm~rciallindustrial development on 135 acres and 258 housing units. Wastewater from the VGCC site will be collected and treated by the Metropolitan Council- Environmental Services Division. Total anticipated volumes of generated waste were not estimated in previous AUAR's but are estimated here as follows: City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 22 I Waste generated by business park = 0.07 GPO/sf Waste generated by residential = 274 GPO/unit Total Waste Generated= (0.07GPO/sfx 2,100,000sf) + (274 GPO/unit x 258 units)= 217,692 GPO The proposed development is part of the area recently approved for MUSA expansion. The project site was slated as business park at the time of this approval by the Metropolitan Council. The Metropolitan Council's Chaska interceptor is also located adjacent to the site. Sanitary sewer will be installed as part of the development. The proposed wastewater collection system, interceptor, and treatment plant all have adequate capacities to accommodate waste generated by development. Option B Option B includes approximately 1,300,000 sf of commerciaVindustrial development on 91 acres and 565 housing units. Wastewater from the VGCC site will be collected and treated by the Metropolitan Council- Environmental Services Division. The development is anticipated to generated the following wastewater volumes: Waste generated by business park = 0.07 GPO/sf Waste generated by residential = 274 GPO/unit Total Waste Generated= (0.07 GPO/acre x 1,300,000sf) + (274 GPO/unit x 565 units)=245 ,8 10 GPO The proposed development is part of the area recently approved for MUSA expansion. The project site was slated as business park at the time of this approval by the Metropolitan Council. The Metropolitan Council's Chaska interceptor is also located adjacent to the site. Sanitary sewer will be installed as part of the development. The proposed wastewater collection system, interceptor, and treatment plant all have adequate capacities to accommodate waste generated by development. 19. GEOLOGIC HAZARDS AND SOIL CONDITIONS 19. Geologic hazards and soil conditions. A map should be included to show any groundwater hazards identified. A standard soils map for the area should be included. a. Approximate depth (infeet) to groundwater:_~minimum 5 average to bedrock: 5 minimum 20 average Describe any ofthefollowing geologic site hazards to groundwater and also identify them on the site map: sinkholes, shallow limestone formations or karst conditions. Describe measures to avoid or minimize environmental problems due to any of these hazards. Option A and B Gnformation from 2000 AUAR and new information) There are no known sinkholes or karst formations within the site. Shallow limestone is present on the site. Test pits excavated on-site have identified sandstone overlaying the limestone. b. Describe the soils on the site, giving NRCS (SCS) classifications, if known. Discuss soil granularity and potential for groundwater contamination from wastes or chemicals spread or spilled onto the soils. Discuss any mitigation measures to prevent such contamination. Option A and B Gnformation from 2000 AU AR with minor modifications) FIGURE 13 shows information from the Scott County Soil Survey for the sites. Soils on the site generally include the following: City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 23 \ , CdA - Copas Silt Loam, 0-2%. Very poorly drained soils derived from shallow deposits of silty or loamy outwash overlying limestone bedrock. Good drainage in most places but is some areas drainage is restricted by bedrock. DaA - Dakota Loam, 0-2%. Moderately well to well drained soils that formed under prairie grasses. Found on sandy outwash plains and terraces. Underlain by sand or fme gravel. De - Duelm Fine Sandy Loam. 0-3%. Well drained to moderately well drained soils of the terraces derived from wind and water assorted fme sands. Dg - Dune Land. Somewhat excessively drained soils consisting of loose sandy material.. EaA - Esterville Sandy loam, 0-2%. Moderately well drained soils that developed under prairie grasses and sandy outwash plains and terraces. HeA - Hubbard Loamy Fine Sand, 0-2%. Somewhat excessively drained soils on sandy terraces. Ia - Isanti Fine Sandy Loam, 0-2%. Poorly drained soils on depressions and flats. Derived from wind and water sorted fme sands. Water table is high much of the year. Ma- Marsh. Very poorly drained soils in lakes and ponds. PbA - Peat and Muck, 0-2%. Organic soils in very poorly drained depressions. Sc - Stoney Land. Moderately well drained to well drained soils located mainly on terraces. Limestone and sandstone bedrock underlies this land at depths of 6 to 36 inches. Ta - Terrace Escarpments. Moderately well to well drained sandy or gravelly soils on narrow, steeply sloping areas between nearly level terraces and the bottom lands or between one terrace and anotheL ThB - Terril Sandy Loam, 0-2%. Moderately well to well drained soils. ZaA, ZaA2, ZaB - Zimmerman Fine Sand, 0-6%. Excessively drained, windblown sands on timbered terraces. These soils generally are described as having a hydrologic description of A or B. "A" soils have high infiltration rates from 0.3 to 0.5 inches per hour. "B" soils have moderate infiltration rates of 0.15 to 0.30 inches per hour. During construction, equipment will require refueling. Fuel is anticipated to be brought to tehs ite as needed and that not storage will occur on-site. A fueling pad of clay with a slight berm will be constructed on site to assure that any accidental spills will be contained to prevent fugitive migration of petroleum products. A Phase I Environmental Assessment was conducted for the property. The assessment indicated that there are no hazardous materials located on the site. ~ Local residents have suggested that the cessation of dewatering at the nearby Shiely/CAMAS limestone quarry could cause the water table to rise close to the ground surface, thereby making groundwater more susceptible to contamination. Located about one mile northeast of the proposed development, the quarry began dewatering in 1967 and currently has a permitted annual dewatering volume of2.75 billion gallons. The quarrying and dewatering occur in the dolomite limestone bedrock of the Prairie du Chien group. In the vicinity of the quarry (the proposed development and Dean's Lake) the Prairie du Chien is overlain by typically 10- to 40 feet of alluvial sand, with a thicker outwash deposit (about 60 to 70 feet) just to the south. A recent groundwater modeling study conducted for the Metropolitan Council (Barr Engineering, 1998) includes predictions of the bedrock groundwater level changes that will result from cessation of the quarry dewatering. Beneath the proposed development, the predicted rebound in Prairie du Chien groundwater level ranges from less than 1 foot to a maximum of7 feet, occurring at the proposed development's northeast comer. City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 24 . However, the above predictions do not apply to groundwater levels in the surficial sand aquifer (i.e. to the water table) in the quarry-proposed development~Dean's Lake vicinity. In this vicinity, the MDNR has investigated groundwater levels as related to the quarry dewatering on two occasions: during November 1979-July 1980 initially (Beissel and Ford, 1982) and during November 1996 - May 1997 (Drivas, 1997). Both studies entailed groundwater level observations in the bedrock and the surficial sand during periods within which quarry dewatering ceased for more than a month and then resumed. Both studies found that, whereas bedrock groundwater levels clearly responded to dewatering changes, groundwater levels in the surficial sand aquifer did not. Both studies also found that groundwater levels in the surficial sand were substantially higher than in the bedrock (6 to 23 feet higher in the 1979-1980 study, based on more than six wells each in the bedrock and the alluvium; 16 feet higher in the 1996-1997 study, based on the Czaja domestic well in the bedrock and an adjacent observation well in the surficial sand.) The two MDNR studies reached essentially the same conclusion concerning the bedrock and surficial sand aquifers: the aquifers "function as separate systems" (Beissel and Ford, 1982) and apparently are not "hydrogeologic ally separated" (Dravas, 1997). Therefore, cessation of the quarry dewatering is expected to yield no significant water table rebound in the area of the proposed development. 20. SOLID WASTES; HAZARDOUS WASTES; STORAGE TANKS 20. Solid wastes; hazardous wastes; storage tanks. For a, generally only the estimated total quantity of municipal solid waste generated and information about any recycling or source separation programs of the RGU need to be included. No response is necessary forb. For c,potentiallocations of storage tanks associated with commercial uses in the AUAR should be identified (e.g. gasoline tanks at service stations). a. Describe the types, amounts, and compositions of solid or hazardous wastes to be generated, including animal manures, sludges and ashes produced during construction and operation. Identify the method and location of disposal. For projects generating municipal solid waste indicate if there is a hazardous waste minimization plan and routine hazardous waste reduction assessments. Option A (Information from the 2002 AUAR) The business portions of the Valley Green Corporate Center /Dean's Lake Residential development will acquire its solid waste storage and disposal services through private contractors. It will be at the discretion of the individual business owners to contract with independent solid waste collectors of their choosing. Initial quantities of solid waste are not known atthis time. Hazardous waste generation is not anticipated on the Valley Green Corporate Center property. The proposed 60 acres (approx.) of residential development is required to have solid waste collection and disposal included with municipal utility services as part of association fee. Option B The business portions of the Valley Green Corporate Center !Dean's Lake Residential development will acquire solid waste storage and disposal services through private contractors. It will be at the discretion of the individual business owners to contract with independent solid waste collectors of their choosing. Initial quantities of solid waste are not known at this time. Hazardous waste generation is not anticipated on the Valley Green Corporate Center property. The proposed 80 acres (approx,) of residential development is required to have solid waste collection and disposal included with municipal utility services as part of association fee. City of Shakopee Valley Green Corporate Center 2003 AUAR Page - 25 . b. Indicate the number, locatidn; size and use of any above or belowground tanks to be used for storage of petroleum products or other materials (except water). Option A and B (Information from the 2002 AUAR with additional information) A convenience store with gas service is a potential land use within the project site. This convenience store would be located at the CSAH 83 / CSAH 16 intersection and would require an underground storage tank to store the fuel. This storage tank should be installed following applicable local, State and Federal guidelines (MN Rule 7150). It is anticipated that the gas station may also have an above ground propane tank and the businesses within the site may have fuel tanks on-site. These facilities will be installed and maintained according to applicable local, State and Federal guidelines. 21. TRAFFIC 21. Traffic. For most AUAR reviews a relatively detailed traffic analysis will be needed, especially if there is to be much commercial development in the AUAR area or if there are major congested roadways in the vicinity. The results of the traffic analysis must be used in the response to item 23 and to the noise aspect of item 25. Instead of responding to the information called for in item 22, the following information should be provided: - a description and map of the existing and proposed roadway system, including state, regional, and local roads to be affected by the development of the AUAR area. This information should include existing and proposed roadway capacities and existing and projected background (i.e.,. without the A UAR development) traffic volumes; - trip generation data --trip generation rates and trip totals---for each major development scenario broken down by land use zones and/or other relevant subdivisions of the area. The projected distributions onto the roadway system must be included; - analysis of impacts of the traffic generated by the AUAR area on the roadway system, including: comparison of peak period total flows to capacities and analysis of Levels of Service and delay times at critical points (if any); - a discussion of structural and non-structural improvements and traffic management measures that are proposed to mitigate problems; Note: in the above analyses the geographical scope must extend outward asfar as the traffic to be generated would have a significant effect on the roadway system and traffic measurements and projections should include peak days and peak hours, or other appropriate measures related to identifying congestion problems, as well as ADTs. OPTION A (Information from the July 2002 AUAR - APPENDIX B.2) Subsequent to the acceptance oftheAUAR dated July, 2000, the City of Shako pee has pursued the reconstruction ofCR 83 and the relocation ofCSAH 16 to the south boundary ofVGCC. "... the improvements to CSAH 83 and CSAH 16 are currently under constnlction. The improvements are based on traffic projections including, the traffic generation from the Valley Green Corporate Center original concept plan [sic - as accepted in the July, 2000 AUAR] and additional background traffic growth on both CSAH 83 and CSAH 16. " 8 Given that the current traffic generation projections (22,701 Net Total Trips9) are approximately 29% less than those included in the July, 2000 AUAR (31,760 Net Total Trips 10) and Mr. Rickart's statement (above) concerning the actual design of the road improvements, it is concluded that the project, as currently proposed, would have measurably less detrimental environmental impacts than were included in the accepted AUAR from July, 2000. 8 Rickart, Charles T., P.E., WSB and Associates, Inc., in email to Ron Roetzel, Bolton & Menk, Inc., dated July 1,2002. 9 RLK-Kuusisto, Ltd., Revision of the Alternative Urban Areawide Review, June 4,2002, page 6. 10 RLK-Kuusisto, Ltd., Revision of the Alternative Urban Areawide Review, June 4,2002, page 5. City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 26 . The site plan for the Valley Green Corporate Center involves the proposed improvement and realignment of CR 83/CSAH 16. This section summarizes the details of the Traffic Impact Studies 11 conducted to analyze the resulting traffic impacts. Full details on the Traffic Impact Studies can be found in the APPENDIX B.2. Existing and Proposed Roadway System The main roadways of the project site can be found in FIGURE 22-1, APPENDIX B.2. Major roadways include US 169 (principal arterial), CR 83 (A minor arterial) and CSAH 16 (B minor arterial). US 169 is a 4-lane divided highway, running east to west and acts as the northern border of the project site. US 169 is also the only major parallel route to the area. CR 83 is a 4-lane highway from US 169 to CSAH 16. It coooects with the City of Shakopee at the Highway 101 intersection, and serves as a major route to Mystic Lake Casino, which is located to the south. CSAH 16 runs east to west for the majority of the southern boundary of the project site. CSAH 16 eventually heads in a northwest direction and acts as a major direct link to downtown Shakopee for area residents. The site plan for the Valley Green Corporate Center includes the proposed improvement and realignment of CR 83/CSAH 16 in accordance with the City of Shakopee' s draft Transportation Plan. An illustration of the proposed realignment can be found in FIGURE 22-5, APPENDIX B.2. This proposed action would include the straightening of CSAH 16 along the southern border so that it would intersect with CR 83 at a 90-degree angle and farther to the south. The portion of CSAH 16 that runs diagonally through the proposed development would be removed. Local residents have voiced their opposition to the proposed realignment. Many residents along CSAH 16 are opposed to the realignment because it takes away their direct route to downtown Shakopee. These residents feel the realignment will require additional travel time through the added segment along CR 83 and two intersections. The 5-year capital improvement plan for the City of Shakopee includes the extension of 17th A venue (FIGURE 22-5, APPENDIX B.2), which would give local residents an alternative route to downtown Shakopee. However the City and Scott County need to agree on the extension of 17th A venue taking place. Trip Generation Data According to the Traffic Impact Study 12, "trip generation data was calculated based on a 20 year traffic forecast, and a background growth rate of 1.5 percent per year. This growth rate is considered reasonable for the area surrounding the proposed development. Data was generated assuming two different land use options, an "Office Service" land use and a "Business Park" land use. The "Office Service" land use assumes 25 percent office use and 75 percent warehouse use. These figures are based on reviews of similar uses in the area."l3 . Business Park Land Use Traffic volumes for the trip generation estimates a Business Park land use are illustrated in FIGURE 22-3, APPENDIX B.2. These traffic volumes include a diversion of approximately 35 percent of the southbound left- turns from the CR 83/Site Driveway intersection to the CSAH l6/Site Driveway intersection. This diversion is for southbound AM peak traffic only. Traffic numbers being diverted were determined by calculating the reserve capacity at the CR 83/County Road 16 and CSAH l6/Site Driveway intersection and rerouting the traffic from the overcapacity site driveway on CR 83 to the under capacity drive on CSAH 16. This reserve capacity was calculated at each intersection using critical lane volumes. 11 SRF Consulting Group, Inc.; WSB and Associates, Inc. 1999.

I I Office Service Land Use Traffic volumes for the trip generation estimates an Office Service land use are illustrated in FIGURE 22-4, APPENDIX B.2. Traffic volumes for the Office Service land use are similar to those of the Business Park use, but resulted in lower trip generation estimates. Peak AM left-turn volumes for southbound traffic do not change between the alternatives. However, peak PM left-turn volumes drop by less than 100 vehicles per hour. Again traffic volumes include a diversion, 25 percent, between the two site driveway intersection and uses the same methodology as described previously for the Business Park land use. Both alternatives were analyzed to determine the accuracy of the percentage diverted. The proposed site plan indicates commercial land uses nearest the access onto CR 83, office/warehouse to the east and office towers in the northeast comer of the site. It was determined reasonable to assume that familiar users such as office employees could easily divert to the alternate south access. Traffic Impacts and Proposed Mitigation The Valley Green Corporate Center is estimated to result in approximately 32,000 to 40,000 additional weekday trips. Due to its location (south of US 169), there are few parallel routes to the area. As a result, it is estimated that 55 percent of site-generated traffic will travel either to the north or from the north on CR 83. This results in peak AM hour volumes of 1,300 to 1,600 vehicles and problems with the number ofleft tums into the site from the north. The most critical queuing location is the southbound left turns at the CR 83/Site Driveway intersection. Mitigation for this area could involve a continuous left-turn lane starting from the CR 83/US 169 south ramp intersection, tapering to a second left-turn lane. This would add additional storage for the left-turn vehicles. This could easily be accomplished through proper striping and signing, but would require Mn/DOT approval due to the proximity to the trunk highway ramp intersection. Queuing problems from US 169 on CR 83 could also be mitigated through the use of special traffic signal timing. The CSAH 16/Site Driveway intersection should also be reviewed periodically for traffic signal warrants. A traffic signal is scheduled to be installed by the year 2017 in order to reserve capacity required for the operation of the CR 83/Site Driveway intersection. According to the results of the Traffic Impact Study 14, all individual intersections will be operating at a Level of Service (LOS) D or better during both AM and PM peak hours, for the design year 2017. A LOS of A through D is typically acceptable (under capacity), LOS E is near capacity, and LOS F is over capacity. An overall arterial analysis indicates that the entire corridor would also be at a LOS D or better for both northbound and southbound traffic during AM and PM hours. Because of the coordinated system however, arterial.LOS at specific intersections may deteriorate to an E, and in the case of the north US 169 ramp intersection an F during AM and PM hours. The reduction in LOS at the north US 169 ramp is a result of the reduction in the amount of green time allocated for the north and south traffic. This specific cycle length deters from the amount of green time allocated for the side streets" therefore deteriorating the intersection Levels of Service. TABLE 22-1A shows Level of Service and Queue Length analysis for CR 83-12th Ave to CSAH 16. As stated above, the proposed development will generate a significant amount of traffic resulting in unacceptable LOS at certain locations adjacent to the site. Additional capacity and/or access points should be considered to more effectively mitigate traffic impacts. The source of the background traffic of 1.5% is accepted by both the City of Shakopee and Scott County as sufficient to account for future growth in the immediate area. It is recommended that due to the potential impacts to the LOS ef at the access points to the site, that the City monitor the traffic conditions as the site develops. Negotiations for access points to this site are still in progress with both Scott County and Mn/DOT. The RGU may, as a mitigation measure, impose limits on the size, type and location of particular developments based upon the traffic impacts of the adjacent access points, and correlate the development potential of this site with the acceptable level of service of the access points. This can be done as the development occurs, and through monitoring of the traffic volumes at the access points. "The City of Shakopee's Transportation Plan includes a chapter on the City's transit system. The City's transit mission statement is 'To evaluate and improve performance, efficiency, and productivity of local transit system 14 SRF Consulting Group, Inc.; WSB and Associates, Inc. 1999. Traffic Impact Study for Realignment orCR 83/CSAH 16. Prepared for Valley Green Corporate Center. City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 29 , identifYing the transit service needs of all citizens and delivering the appropriate transit services while balancing the available energy and financial resources. ' The City of Shako pee is currently not served by the Metropolitan Transit Service. Instead, the City of Shako pee is the provider through Shakopee Area Transit (SAT) alternative transit serVices. The services currently provided are: (1) dial-a-ride service within the City of Shako pee; (2) commuter van pools. Express bus service to Eden Prairie Center is expected to be re-instated this year. The transit ridership levels overall have been steadily increasing. With the opening of the new Bloomington Ferry Bridge and US 169 the pace of development in Shakopee has increased significantly. In order to meet increased demand, the City will need to work with other transit providers to ensure that its residents can make the transit connections, they need to get across the metropolitan area to jobs and other destinations. With the increased residents and development around the area of the US 169 and CR 83 and with CSAH 17 the City has identified the need for a park-and-ride site in these areas. A park-and-ride facility has been identified in the northwest quadrant of us 169 and CR 83 and in the northwest quadrant of us 169 and CSAH 17. The City will be committed to work with Valley Green Corporate Center to encourage carpools and van pools (within) the proposed site, as it develops." 15 The realignment of CSAH 16 is still under review by the City of Shakopee, and Scott County. The City's traffic consultant using the existing lane configuration. of CR 83 and CSAH 16 completed a preliminary analysis of a non- realignment concept. This determined that significant changes in the density of the project would be required in. order to accommodate the turning traffic. This density however, would not conform to Metropolitan Council policy of smart growth. Thus, this study at least builds the need for improvements to both CR 83 and CSAH 16. The realigriment of CSAH 16 also has implications in a regional sense which has impacts that are beyond the scope of this F AUAR. It is therefore recommended that additional study be completed on this roadway relocation to analyze the impacts to the current users of CSAH 16 and the existing travel patterns, as well as the impacts to adjacent site development. In 1998, representatives from the City of Shako pee and Scott County have held discussions with representatives from MnlDOT regarding the CR 83 and CSAH 16 concept plan and the traffic impacts to the CR 83 / US 169 interchange. Concept plans have been developed for this area based upon the comments received from MnlDOT and includes signals and dual left turn lanes at the westbound US 169 ramp. A copy of these concepts is shown in FIGURE 22-5, APPENDIX B.2. Other potential mitigation measures to the site traffic include the extension of 17th A venue to connect with the intersection of CR 83 and realigned CSAH 16. It is recommended that additional study be completed to review whether this is a viable improvement to reduce the traffic impacts potentially generated by the development of this site.' This roadway extension is in the City of Shako pee's Transportation Plan, and would and an important east-west circulation roadway south of US 169. OPTION B (U{>dated Analysis - See Appendix B.3) Subsequent to the acceptance of the AUAR dated July, 2000, and the update dated July, 2002, the City of Shakopee has pursued and completed the reconstruction ofCSAH 83 and the relocation ofCSAH 16 to the south boundary of the Valley Green Corporate Center. The improvements were based on traffic projections including the traffic generation from the Valley Green Corporate Center original concept plan [sic - as accepted in the July, 2000 AUAR] and additional background traffic growth on both CSAH 83 and CSAH 16." 16 Given that the current traffic generation projections (16,982 Net Total Trips) are approximately 25% less than those included in the July 2002 AUAR (22,701 Net Total Trips2) which were 29% less than those included in the July 2000 15 Rickart, Chuck, WSB Associates, attachment to E-mail to Del Jackman, Bolton & Menk, June 9, 2000, page 5. 16 Rickart, Charles T., P.E., WSB and Associates, Inc., in email to Ron Roetze1, Bolton & Menk, Inc., dated July 1,2002. City of Shakopee Valley Green Corporate Center 2003AUAR Page - 30 I AUAR (31,760 Net Total Trips 17), it is concluded that Option B would have measurably less detrimental environmental impacts than were included in the accepted AUAR from July, 2000. The following section summarizes the details of the Traffic Impact Studies 18 conducted to analyze the resulting traffic impacts. Full details on the Traffic Impact Studies can be found in the APPENDIX B. Existing and Proposed Roadway System The main roadways of the project site can be. found in FIGURE 22-1, APPENDIX B.3. Major roadways include US Highway 169 (principle arteria!), CSAH 83 (A minor arterial) and CSAH 16 (B minor arterial). US Highway 169 is an east-west, 4-lanedivided highway and acts as the northern border of the project site. US Highway 169 is also the only major parallel route to the area. CSAH 83 is a 4-lane highway from US 169 to CSAH 16. It connects with the City of Shakopee at the Trunk Highway 101 intersection, and serves as a major route to Mystic Lake Casino, which is located to the south. CSAH 16 is an east/west road with ajog on CSAH 83 for the majority of the southern boundary of the project site. CSAH 16 eventually heads in a northwest direction and acts as a major direct link to downtown Shakopee. The 5-year capital improvement plan for the City of Shakopee includes the extension of 17th Avenue (FIGUR..€ 22-1, APPENDIX B.3), which would give local residents an alternative route to downtown Shakopee. However the City and Scott County need to agree on the extension of 17th A venue taking place. Data Collection Turning movement counts had not been collected since completion of the roadway improvements, as proposed in the July 2000 AUAR~ New data was collected the weeks of April 21 5t and April 28th, 2003 along CSAH 83 during the morning and afternoon peak hours at the following intersections: 12th Avenue, Secretariat Drive US Highway 169 West Ramp US Highway 169 East Ramp CSAH 16 West and CSAH 16 East The existing (2003) AM and PM peak hour turning movements and existing lane geometry is illustrated in FIGURES 22-2 and 22-3, APPENDIX B.3, respectively. Trip Generation Data Trip generation data for the peak hours of traffic and average daily traffic (ADT) (TABLE 22-1-0PTIONB) was calculated for the year 2010 (proposed year after full build conditions) using the data and methodologies contained in the 6th Edition of Trip Generation, published by the Institute ofTransportationEngineers (lTE).

Industry accepted standards included within ITE's Trip Generation Handbook were used to calculate the shared trip and pass-by trip reductions for the currently planned uses. The trip distribution percentages deveioped for Scott County by SRF Consulting Group, Inc. were used to distribute the trip generation estimates. The trip generation percentages used are as follows: . 35 percent to/from the east of US Highway 169; . 18 percent to/from the east of County Road 16; . 12 percent to/from the south on CSAH 83; . 10 percent to/from the west on the future 17th A venue extension; . 10 percent to/from the west on US Highway 169; . 5 percent to/from the west on County Road 16; . 10 percent to/from the north on CSAH 83. A background growth rate of 1.5 percent per year was added to the data that was collected to develop the 2010 projected traffic volumes. Based on discussions generated from the 2000 and 2002 AUAR for this site, this growth rate is considered reasonable for the area surrounaing the proposed development. Projected traffic was also generated for the year 2020, ten years after completion of the proposed development, utilizing the same growth rate. FIGURES 22-4 and 22-5, APPENDIX B.3 illustrate the projected 2020 build AM and PM peak hour turning movements. Proposed Access Access to the site is proposed via three entrances: one on CSAH 83 and two on CSAH 16. The primary commercial entrance would be on CSAH 83 across from the west leg ofCSAH 16. The fIrst access to the east ofCSAH 83 on CSAH 16 would be closed to eastbound traffIc (right-inlright-out only). The second access would be a full access into the residential area. Traffic Impacts and Proposed Mitigation The operational analysis was completed using the traffic modeling and simulation software Synchro/SimTraffic Version 5, Build 323. This model is based on the 2000 Highway Capacity Manual, published by the Transportation Research Board. The procedures describe operating conditions at intersections in terms of Level of Service (LOS). These operations are given letter designations with "A" representing the best operating condition and "F" representing the worst. Generally, level of service "D" represents the threshold for an acceptable overall intersection operating condition during a peak hour. The recent construction includes some lanes that are striped to be excluded at this time. The analysis assumes that these lanes striped out for future use would be re-striped for use with the proposed development. The extension of 17th A venue to connect with the intersection of CSAH 83 and realigned CSAH 16 was included in the analysis, since it is included in the City of Shakopee five-year CIP. This roadway extension is in the City of Shakopee's Transportation Plan, and would add an important east-west circulation roadway south of US 169. City of Shakopee Valley Green Corporate Center 2003 AUAR Page - 32 J The Valley Green Corporate Center is estimated to result in approximately 17,000 additional weekday trips. Due to its location (south of US Highway 169), there are few parallel routes to the area. As a result, it is estimated that 79 percent of site-generated traffic will travel either to the north or from the north on CSAH 83. This results in AM peak hour volumes of 1,300 to 2,200 and PM peak hour volumes of 1,500 to 3,200. The most critical queuing locations are at the westbound left turn lanes at the US Highway 169 west ramp and the southbound left turns at the US Highway 169 east ramp. The maximum queue lengths are approaching the exiting turn lane lengths; however, the queue lengths are not exceeding the existing turn lane lengths for the modeled 2020 build condition. The CSAH 16/Site Driveway intersection should also be reviewed periodically for traffic signal warrants. A traffic signal is scheduled to be installed by the year 2020 to reserve capacity required for the operation of the CSAH 83/Site Driveway intersection. According to the results of the traffic analysis, all individual intersections will be operating at a Level of Service (LOS) D or better during both AM and PM peak hours, for the design year 2020. A LOS of A through D is typically acceptable (under capacity), LOS E is near capacity, and LOS F is over capacity. An overall arterial analysis indicates that the entire corridor would also be at a LOS D or better for both northbound and southbound traffic during AM and PM hours. Because of the coordinated system, however, arterial LOS at specific intersections may deteriorate to an E, and in the case of the 12th Avenue intersection, an F during PM peak hours. The reduction in LOS at this intersection is a result of the reduction in the amount of green time allocated for the north and south traffic. This specific cycle length deters from the amount of green time allocated for the side streets, therefore deteriorating the intersection Levels of Service.

However, with the roadway improvements complete, the LOS is maintained at an overall C or better with no movements below a LOS D. The City of Shakopee is currently not served by the Metropolitan Transit Service. Instead, the City of Shakopee is the provider through Shakopee Area Transit (SAT) alternative transit services. The services currently provided are: (1) dial- a-ride service within the City of Shakopee; (2) commuter vanpoo1s. Express bus service to Eden Prairie Center is expected to be reinstated this year. The transit ridership levels overall have been steadily increasing. With the opening of the new Bloomington Ferry . Bridge and US 169, the pace of development in Shakopee has increased significantly. In order to meet increased demand, the ~ity will need to work with other transit providers to ensure that its residents can make the transit connections, they need to get across the metropolitan area to jobs and other destinations. With the increased residents and development around the area of the US 169 and CSAH 83 and with CSAH 17, the City has identified the need for a pm-k-and-ride site in these areas. A park-and-ride facility has been identified in the northwest quadrant of US 169 and CSAH 83 and in the northwest quadrant of US 169 and CSAH 17. The City will be committed to work with Valley Green Corporate Center to encourage carpools and vanpools (within) the proposed site, as it develops." 19 From the results of the analyses, it is concluded that no mitigation measures will be necessary for either the 2010 or 2020 projected build years. However, it is suggested that operations at all intersections studied be monitored in the future to determine if any road improvements become necessary. Text from the July 2000 AUAR (included here for reference - APPENDIX B.I) The site plan for the Valley Green Corporate Center involves the proposed improvement and realignment ofCR 83/CSAH 16. This section summarizes the details of the Traffic Impact Studies 20 conducted to analyze the resulting traffic impacts. Full details on the Traffic Impact Studies can be found in VOLUME 2, APPENDIX C. Existing and Proposed Roadway System The main roadways of the project site can be found in FIGURE 22-1, APPENDIX B.L Major roadways include US 169 (principal arterial), CR 83 (A minor arterial) and CSAH 16 (B minor arterial). US 169 is a 4 lane divide highway, 19 Rickart, Chuck, WSB Associates, attachment to E-mail to Del Jackman, Bolton & Menk, June 9,2000, page 5. 20 SRF Consulting Group, Inc.; WSB and Associates, Inc. 1999. Traffic Impact Study for Realignment ofCR 83/CSAH 16. Prepared for Valley Green Corporate Center. City of Shakopee Valley Green Corporate Center 2003 AUAR Page - 34 I running east to west and acts as the northern border of the project site. US 169 is also the only major parallel route to the area. CR 83 is a 41ane highway from US 16.9 to CSAH 16. It connects with the City of Shakopee at the Highway 101 intersection, and serves as a major route to Mystic Lake Casino, which is located to the south. CSAH 16 runs east to west for the majority of the southern boundary of the project site. CSAH 16 eventually heads in a northwest direction and acts as amajor direct link to downtown Shakopee for area residents. The site plan for the Valley Green Corporate Center includes the proposed improvement and realignment of CR 83/CSAH 16 in accordance with the City of Shakopee' s draft Transportation Plan. An illustration of the proposed realignment can be found in FIGURE 22-5, APPENDIX B.1. This proposed action would include the straightening of CSAH 16 along the southern border so that it would intersect with CR 83 at a 90 degree angle and farther to the south. The portion of CSAH 16 that runs through the proposed development would be removed. Local residents have voiced their opposition to the proposed realignment. Many residents along CSAH 16 are opposed to the realignment because it takes away their direct route to downtown. Thus requiring additional travel time through the added segment along CR 83 and two intersections. The 5-year capital improvement plan for the City of Shakopee includes the extension of 17th Avenue (FIGURE 22-5, APPENDIX B.1), which would give local residents an alternative route to downtown Shakopee. However the City and Scott County need to agree on the extension of 17th A venue taking place. Trip Generation Data According to the Traffic Impact Study 21, "trip generation data was calculated based on a 20 year traffic forecast, and a background growth rate of 1.5 percent per year. This growth rate is considered reasonable for the area surrounding the proposed development. Data was generated assuming two different land use options, an "Office Service" land use and a "Business Park" land use. The "Office Service" land use assumes 25 percent office use and 75 percent warehouse use. These figures are based on reviews of similar uses in the area.,,22 Business Park Land Use Traffic volumes for the trip generation estimates assuming a Business Park land use are illustrated in FIGURE 22- 3, APPENDIX B.1. These traffic volumes include a diversion of approximately 35 percent of the southbound left- turns from the CR 83/Site Driveway intersection to the CSAH 16/Site Driveway intersection. This diversion is for southbound AM peak traffic only. Traffic numbers being diverted were determined by calculating the reserve capacity at the CR 83/County Road 16 and CSAH 16/Site Driveway intersection and rerouting the traffic from the overcapacity site driveway on CR 83 to the under capacity drive on CSAH 16. This reserve capacity was calculated at each intersection using critical lane volumes. Office Service Land Use Traffic volumes for the trip generation estimates assuming an Office Service land use are illustrated in FIGURE 22-4, APPENDIX B.1. Traffic volumes for the Office Service land use are similar to those of the Business Park use, but resulted in lower trip generation estimates. Peak AM left-turn volumes for southbound traffic do not change between the alternatives. However, peak PM left-turn volumes drop by less than 100 vehicles per hour. Again traffic volumes include a diversion, 25 percent, between the two site driveway intersection and uses the same methodology as described previously for the Business Park land use. Both alternatives were analyzed to determine the accuracy of the percentage diverted. The proposed site plan indicates commercial land uses nearest the access onto CR 83, office/warehouse to the east and office towers in the northeast comer of the site. It was determined reasonable to assume that familiar users such as office employees could easily . divert to the alternate south access. Traffic Impacts and Proposed Mitigation The Valley Green Corporate Center is estimated to result in approximately 32,000 to 40,000 additional weekday trips. Due to its location (south of US 169), there are few parallel routes to the area. As a result, it is estimated that 55 percent of site-generated traffic will travel either to the north or from the north on CR 83. This results in peak AM hour volumes of 1,300 to 1,600 vehicles and problems with the number ofleft turns into the site from the north. The most critical queuing location is the southbound left turns at the CR 83/Site Driveway intersection. Mitigation for this area could 21 SRF Consulting Group, Inc.; WSB and Associates, Inc. 1999. Traffic Impact Study for Realignment ofCR 83/CSAH 16. Prepared for Valley Green Corporate Center. 22 SRF Consulting Group, Inc.; WSB and Associates, Inc. 1999. Traffic Impact Study for Realignment of CR 83/CSAH 16. Prepared for Valley Green Corporate Center. City of Shakopee Valley Green Corporate Center 2003AUAR Page - 35 . involve a continuous left-turn lane starting from theCR 83/US 169 south ramp intersection, tapering to a second left-turn lane. This would add additional storage for the left-turn vehicles. This could easily be accomplished through proper striping and signing, but would require MnlDOT approval due to the proximity to the trunk highway ramp intersection. Queuing problems from US 169 on CR 83 could also be mitigated through the use of special traffic signal timing. The CSAH l6/Site Driveway intersection should also be reviewed periodically for traffic signal warrants. A traffic signal is scheduled to be installed by the year 2017 in order to reserve capacity required for the operation of the CR 83/Site Driveway intersection. According to the results of the Traffic Impact Study 23, all individual intersections will be operating at a Level of Service (LOS) D or better during both AM and PM peak hours, for the design year 2017. A LOS of A through D is typically acceptable (under capacity), LOS E is near capacity, and LOS F is over capacity. An overall arterial analysis indicates that the entire corridor would also be at a LOS D or better for both northbound and southbound traffic during AM and PM hours. Because of the coordinated system however, arterial LOS at specific intersections may deteriorate to an E, and in the case of the north US 169 ramp intersection a F during AM and PM hours. The loss of LOS at the north US 169 ramp is a result of the amount of green time allocated for the north and south traffic. This specific cycle length deters from the amount of green time allocated for the side streets, therefore producing unsatisfactory Levels of Service. The TABLE in APPENDIX B.l shows Level of Service and Queue Length analysis for CR 83-12th Ave to CSAH 16. As stated above, the proposed development will generate a significant amount of traffic resulting in unacceptable LOS at certain locations adjacent to the site. Additional capacity and/or access points should be considered to more effectively mitigate traffic impacts. The source of the background traffic of 1.5% is accepted by both the City of Shakopee and Scott County as sufficient to account for future growth in the immediate area. It is recommended that due to the potential impacts to the LOS of the access points to the site, that the City monitor the traffic growth as the site develops. Negotiations for access points to this site are still in progress with both Scott County and Mn/DOT. The RGU may, as a mitigation measure, impose limits on the size, type and location of particular developments based upon the traffic impacts of the adjacent access points, and correlate the development potential of this site with the acceptable level of service of the access points. This can be done as the development occurs, and through monitoring ofthe traffic volumes at the access points. "The City of Shako pee 's Transportation Plan includes a chapter on the City's transit system. The City's transit mission statement is 'To evaluate and improve performance, efficiency, and productivity of local transit system identifying the transit service needs of all citizens and delivering the appropriate transit services while balancing the available energy and financial resources. ' The City of Shakopee is currently not served by the Metropolitan Transit Service. Instead, the City of Shako pee is the provider through Shakopee Area Transit (SAT) alternative transit services. The services currently provided are: (1) dial-a-ride service within the City of Shakopee; (2) commuter vanpools. Express bus service to Eden Prairie Center is expected to be re-instated this year. The transit ridership levels overall have been steadily increasing. With the opening of the new Bloomington Ferry Bridge and US 169 the pace of development in Shakopee has increased significantly. In order to meet increased demand, the City will need to work with other transit providers to ensure that its residents can make the transit connections, they need to get across the metropolitan area to jobs and other destinations. With the increased residents and development around the area of the US 169 and CR 83 and with CSAH 17 the City has identified the need for a park-and-ride site in these areas. Apark-and-ride facility has been identified in the northwest quadrant of us 169 and CR 83 and in the northwest quadrant of US 169 and CSAH 17. The City will be committed to work with Valley Green Corporate Center to encourage carpools and vanpools (within) tbe proposed site, as it develops." 24 The realignment of CSAH 16 is still under review by the City of Shakopee, and Scott County. A preliminary analysis of 23 SRF Consulting Group, Inc.; WSB and Associates, Inc. 1999. Traffic Impact Study for Realignment ofCR 83/CSAH 16. Prepared for Valley Green Corporate Center. 24 Rickart, Chuck, WSB Associates, attachment to E-mail to Del Jackman, Bolton & Menk, June 9,2000, page 5. City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 36 .. a non-realignment concept was completed by the City's traffic consultant using the existing lane configuration ofCR 83 and CSAH 16. This detennined that significant changes in the density of the project would be required in order to accommodate the turning traffic. This density however, would not confonn with Metropolitan Council policy of smart growth. Thus, this study at least builds the need for improvements to both CR 83 and CSAH 16. The realignment of CSAH 16 also has implications in a regional sense which has impacts that are beyond the scope of this FAUAR. It is therefore recommended that additional study be completed on this roadway relocation to analyze the impacts to the current users of CSAH 16 and the existing travel patterns, as well as the impacts to adjacent site development. In 1998, representatives from the City of Shakopee and Scott County have held discussions with representatives from Mn/DOT regarding the CR 83 and CSAH 16 concept plan and the traffic impacts to the CR 83/ US 169 interchange. Concept plans have been developed for this area based upon the comments received from MnlDOT and includes signals and dual left turn lanes at the westbound US 169 ramp. A copy of these concepts is shown in FIGURE 22-5, APPENDIX B.t. Other potential mitigation measures to the site traffic include the extension of 17th Avenue to connect with the intersection of CR 83 and realigned CSAH 16. It is recommended that additional study be completed to review whether this is.a viable improvement to reduce the traffic impacts potentially generated by the development of this site. This roadway extension is in the City of Shako pee's Transportation Plan, and would and an important east-west circulation roadway south of US 169. 22. VEHICLE - RELATED AIR EMISSIONS 22. Vehicle-related air emissions. The guidance provided in "EAW Guidelines: should also befollowedfor an AUAR. Mitigation proposed to eliminate any potential problems may be presented under Item 22 and merely referenced here. The MPCA staffshould be consulted regardingpossible ISP requirements for certain proposed developments; although the RGU may not want to assume responsibility for applyingfor an ISP for specific developments, it may be desirable to coordinate the AUAR and ISP analyses closely. OPTION A (Text from 2002 AUAR) Pollutant emissions will be associated with motor vehicles traveling to and from the project. These and other vehicles already passing through critical intersections contribute to the overall pollutant concentration near the critical intersections serving the project. The most critical pollutant associated with vehicular traffic is Carbon Monoxide (CO) for which I-hour and 8-hour ambient air quality standards have been established by the US Environmental Protection Agency (EP A) and the Minnesota Pollution Control Agency (MPCA). The MPCA I-hour standard is slightly more stringent than the EP A I-hour standard (35 ppm) and will therefore be used in this air quality assessment for the AUAR. The standards are presented in TABLE 2j-l- OPTION A. TABLE 23-1-0PTION A MPCA AMBIENT AIR QUALITY STANDARDS FOR CARBON MONOXIDE . Period Standard I-hour 30 (parts per million) ppm 8-hour 9 (parts per million) ppm The following dispersion modeling was conducted as a part of the AUAR dated July, 2000 and reflected higher traffic volumes, longer wait times and more severe Level of Service conditions than are predicted in the revised scope of project being considered at this time. Previously (July, 2000), the projected ambient air quality CO levels were consistently below the MPCA standards for all receptor locations, for both the I hour and 8 hour exposures. Given that the newly predicted traffic levels, with their corresponding improvements in wait times and Levels of Service, are considerably below of those use in July, 2000, it is concluded that the ambient air quality will not exceed the MPCA standards. City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 37 A CO dispersion analysis was performed for four of the six intersections analyzed for traffic in Item 22. Two of the intersections, CR 83 at 12th Avenue and CSAH 16 at the site access along the south side of the project, are estimated to have less than 2,400 PM Peak Hour approach movements and are not likely to have the potential for high CO concentrations based upon air quality screening guidelines developed in the early 1990s by regional air quality task force. The intersections analyzed for vehicle emissions and air quality are listed in TABLE 23-2. TABLE 23-2-0PTION A INTERSECTIONS EXAMINED FOR CO CONCENTRATIONS PM Peak Hour Approach Volumes (2017) North/South Roadway East/West Roadway Volume LOS CR83 12th Avenue 1,972 C CR83 TH 169 WB Ramp 3,860 D CR83 TH 169 EB Ramp 5,150 B CR83 CSAH 16 6.040 E CR83 17th Avenue (future) 4,130 C South Site Access CSAH 16 1,570 not available The MOBILE SA emissions program was used to estimate vehicle emissions in the year 2017 for which the traffic analysis has been completed. The CAL3QHC dispersion model was used to estimate CO concentrations at receptor sites near each of the intersections listed in TABLE 23-2-0PTION A. Receptor sites 100 feet from the intersection in each of four compass quadrants were assumed since land use immediately adjacent to these intersection are currently undeveloped but could potentially be developed in the future. Carbon Monoxide Background Concentration Background CO monitoring was performed in May of 1996 just north of Lake Susan in Chanhassen and approximately 5.5 miles northwest of the critical intersections analyzed in this AUAR. The observed 1996 background concentrations have been adjusted to worst case annual (winter) concentrations using seasonal adjustment factors and to the 2017 projection year using the ratio of 20 17 to 1996 emission rates from the MOBILE 5A emissions model and assuming an overall regional Vehicle Miles Traveled (VMT) growth of 2% per year. A vehicle Inspection/Maintenance program was assumed in 1996 but not in 2017. The results of this adjustment are shown in TABLE 23-3,:,OPTION A. TABLE 23-3-0PTION A ADJUSTED CO BACKGROUND CONCENTRATIONS FOR 2017 Factor 1996 2017 Emission rate at 25 mph 23.1 20.0 .

The U.S. EP A MOBILE 5A emissions model for 2017 was run with the vehicle mix for the Twin Cities Seven-County Metropolitan Area (without the vehicle inspection and maintenance program that was terminated in 1999). The CAL3QHC model has been used to estimate downwind concentrations of carbon monoxide at receptor sites adjacent to critical intersections identified in TABLE 23-2-0PTION A. Eight hour concentrations associated with each roadway are estimated using a persistence factor of 0.70 applied to the PM peak hour emissions. The assumptions used for the dispersion model are summarized in TABLE 23-4-0PTION A.

PM Peak Hour (I-hour) concentrations are presented in TABLE 23-S-0PTION A. Projected 8- Hour concentrations for No-Build and Build scenario traffic are presented in TABLE 23-6-0PTION A.

However, all of the CO concentrations at this intersection and others are well below the I-hour 30 ppm ambient air quality standard for Carbon Monoxide.

This level as well as others projected at critical intersections are below the 9 ppm 8-hour standard for Carbon Monoxide. Based upon the CO emission and dispersion analysis at these four intersections, it can be seen that the I-hour and 8- hour concentrations all fall below the established standards so that no significant adverse air quality impacts are expected in 2017 because of the project. Given that the above analysis was conducted for traffic levels in excess of the current proposed design, it is concluded that the MPCA standards will be met by the project, as proposed. Option B (Additional Analysis) Vehicle related air emissions are directly related to the amount of motor vehicle travel though an area. The proposed Option B Valley Green Corporate Center will generate additional traffic on the surrounding roadways. A detailed Air Quality analysis was completed for the 2002 AUAR (see Option A). This analysis concluded that no significant adverse Air Quality impacts would be expected. The current proposed land use will generate approximately 25% less total trips at full build than that in the 2002 AUAR. In addition, the increase in background traffic from 2017 to 2020 is estimated at 4.5% (See Section 21, Traffic). Based on the fact that the total traffic in 2020 is estimated to be less than that in the 2002 AUAR, it can be concluded that the proposed project will not have any significant adverse Air Quality impacts.

Any stationary air emissions source large enough to merit environmental review requires individual review. No response is necessary per the EQB guidance. 24. DUST, ODORS, NOISE 24. Dust, odors, noise. Dust, odors, and construction noise need not be addressed in an AUAR, unless there is some unusual reason to do so. The RGU might want to discuss as part of the mitigation plan, however, any dust control or construction noise ordinances in effect. If the area will include or adjoin major noise sources a noise analysis is needed to determine if any noise levels in excess of standards would occur, and if so, to identify appropriate mitigation measures. With respect to trajJic- generated noise, the noise analysis should be based on the traffic analysis of item 21. Option A (Information from 2002 AUAR) The format of this section has been revised. The ADAR dated July 2000 discussed construction impacts and those impacts at specific intersections in the proposed project area caused by traffic. . Construction Impacts - No revision is necessary. The same and similar impacts are anticipated. . Traffic Impacts in Commercial Portion- Given that the revised scope of the project reflects approximately a 29% reduction in traffic generation, it is concluded that the potential impacts will be less than previously determined and accepted in the ADAR dated July, 2000. . Impacts on Residential Receptor Sites - The rezoning of approximately 60 acres of Business Park to Residential housing will allow placement of more critical receptor sites closer to the business park and closer to US 169. A new investigation of the potential noise impacts is necessary and provided. Noise Terminology dB(A) - A umt of sound level expressed in decibels (dB) and A-weighted. DECIBEL - A unit of sound pressure level, abbreviated as "dB". dBA A special weighting of sound pressure that approximates human hearing. dBLin - Raw levels of sound pressure measure as recorded by the equipment. LIO - Lso - The sound level, expressed in dBA, which was exceeded 10 percent (or 50 percent) of the time in a I hour screening. Ldn - Average day-night level which includes a 10 dB weighting factor for night-time readings to allow for increased sensitivity to noise during the night-time hours. Ldn is equal to the Leq (time weighted average) when applied to day-time hours only (7 am to 10 pm) activities. NAC - Refers to "NOISE AREA CLASSIFICATION" as defmed in the Minnesota Rules . Category 1 refers to RESIDENTIAL City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 41 . Category 2 refers to COMMERCIAL. . Category 3.refers to INDUSTRIAL. Construction Impacts Dust, noise and vibration will be associated with the normal grading and construction activities. The following measures to minimize noise and dust emissions will be incorporated into the construction procedures for the project: . All internal combustion motors will be fitted with mufflers and other noise control equipment as specified by the manufacturer. . Construction procedures will comply with Minnesota Rules 7005.0050 on the control of fugitive particulate matter from construction and hauling activities so as to minimize adverse air quality impacts. . Minnesota Rules 7030.0040 on noise limits during daytime and nighttime hours will be complied with to minimize any adverse impacts on the noise environment. Once the project is completed and operational, no unusual dust, odors or noise will be generated except that associated with mechanical equipment located on or adjacent to some of the buildings within the project. Traffic Noise Impacts in the New Residential Areas- Daytime (PM Peak Hour) Minnesota Pollution Control Agency (MPCA) noise standards for residential and commercial land uses are listed in TABLE 25-1- OPTION A TABLE 25-1- OPTION A MPCA DAYTIME NOISE STANDARDS (dBA) Land Use/Noise Metric Daytime Standard NAC-I Residential LIO 65 Lso 60 NAC-2 Commercial LIO 70 Lso 65 NAC-3 Industrial LIO 80 Lso .. 75 For the purpose of this study, two receptor sites were chosen in the proposed residential area. . Site # I is near the south line of the residential area, near CSAH 16, This area is higher and can hear the traffic generated by US I 69and CSAH 16 with few barriers. . Site # 2 is located near the northeast corner of the residential district. Its proximity to Dean's Lake, the treeline shelter from US 169 and the distance from CR 83& CSAH 16, all serve to reduce the overall noise levels found in the model. Three computerized models were prepared to predict the potential noise levels on each site. The following table (TABLE 25-1b-OPTION A) illustrates the results of computerized modeling of the site and the associated noise generators with the ~TAMINA 2.0 program.

In fact, for site # 2 (Northeast), the daytime noise levels will not even exceed the nighttime limits. If some activity in the future (natural or man-made) would severely reduce or eliminate the treeline boundary adjacent to CSAH 16 (Scenario # 2, above), prompt efforts to repopulate the area with trees or some other noise barrier should be undertaken to mitigate noise exposure back to the MPCA standards. Traffic Noise Impacts in the Commercial Areas- Daytime (PM Peak Hour) The following analysis uses the Traffic Volumes andPattems included in the July, 2000 AUAR Minnesota Pollution Control Agency (MPCA) noise standards for residential and commercial land uses are listed in TABLE 25-1-0PTION A. The residential area most likely impacted by noise from immediately adjacent roadways carrying project traffic are those north of CSAH 16 and south of Dean Lake. Areas adjacent to the critical intersections serving the project are most likely to be developed as commercial land uses if such development occurs. It should be noted that under an amendment to Minn. Stat. 9116.07, subd. 2a, these standards no longer apply to roadways except in the cities of Minneapolis and St. Paul. A traffic noise impact analysis is still included in this AUAR using the MPCA standards as planning guidelines although they will be referred to as "standards". Since the project is expected to generate only minimal traffic during the nighttime hours, this evaluation addresses maximum expected daytime noise levels. This noise assessment also addresses the potential impact on noise levels caused by the removal Of trees south of US 169 at the homes south of Dean's Lake. That assessment follows the analysis of noise impacts from immediately adjacent roadways that is presented below. Traffic noise levels have been analyzed for the PM Peak Hour which represents the worst case daytime noise levels for comparison with the MPCA daytime noise standards. Noise levels were analyzed at the receptor sites in the vicinity of the four critical intersections listed in TABLE 23-2-0PTION A and at the residential area north of CSAH 16 and south of Dean's Lake. The STAMINA 2.0 highway noise model was used with the estimated Build traffic developed in Question 21 for the year 2017. An average speed of 40 mph along roadways was assumed near intersections and 45 mph along CSAH 16. A vehicle mix of 3% medium trucks and 1 % heavy trucks was assumed on all of the roadways 25 RLK-Kuusisto, Ltd., Revision of the Alternate Urban Area-wide Review for the Valley Green Corporate Center, June4, 2002, page 11. City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 43 , near the critical intersections. Medium trucks were estimated at 5% and no heavy trucks were assumed on CSAH 16 south of Dean's Lake. The projected LIO and L50 noise levels at receptor sites adjacent to the critical intersections for the PM Peak Hour are presented in TABLE 25-2-0PTION A along with the increase in noise level over the No-Build scenario.

LIO levels are generally above 70 dBA and L50 levels are generally above 65 dBA. A comparison of the projected levels with the NAC-2 (commercial) noise standards is presented in TABLE 25-3- OPTION A.

However, as noted below, the higher NAC-3 (industrial) standards can be applied where certain conditions are met. Building construction and use are exceptions to the MPCA noise standards: Exceptions to the MPCA noise standard allow for a higher standard to be applied under specified conditions. Under Subpart 3 EXCEPTIONS (D) of Minnesota Rules 7030.0050 NOISE AREA CLASSIFICATION, the NAC 3 (industrial) standards can be applied to a land use in NAC 2 (commercial) if the following conditions are met: (1) the building is constructed in such a way that the exterior to interior sound level attenuation is at least 30 dBA (2) the building has year-round climate control, and (3) the building has no areas or accommodations that are intended for outdoor activities Typical commercial construction will meet these requirements. However, no continuous outdoor uses should be permitted in areas for which the LIO is 70 dBA or greater or the Lso is 65 dBA or greater. Assuming that the conditions noted above are met for land uses for which there are no intended outdoor uses, differences between projected levels and the NAC-3 standards are shown in TABLE 25-4~ TABLE 2S-4-0PTION A [sic- based on traffic counts from July, 2000 AAUR] PM PEAK HOUR LEVELS RELATIVE TO NAC-3 STANDARDS at Critical Intersections - (dBA) Receptor Site (100 feet) LIO Lso CSAH 83 at WB Ramp NE -7.9 -7.1 SE -7.8 -6.8 SW -7.8 -7.0 NW -8.5 -7.8 CSAH 83 at EB Ramp NE -7.3 -5.9 SE -6.1 -4.7 City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 45 ~ TABLE 25-4-0PTION A [sic- based on traffic counts from July, 2000 AAUR] PM PEAK HOUR LEVELS RELATIVE TO NAC-3 STANDARDS at Critical Intersections - (dBA) SW -7.0 -5.7 NW -7.5 -6.4 CSAH 83 at CSAH 16 NE -5.6 -4.0 SE -6.5 -4.9 SW -7.0 -5.6 NW -6.5 -5.0 CSAH 83 at 17th Ave. NE -7.6 -6.6 SE -8.3 -7.4 SW -7.9 -7.0 NW -7.1 -6.1 From TABLE 25-4-0PTION A it can be seen that well-constructed commercial buildings (without continuous outside land uses) are likely to comply with the MPCA noise standards. Projected noise levels at the residential area north of CSAH 16 and south. of Dean Lake are presented in TABLE 25-5 and compared with the NAC-l (residential) noise standards. It can be seen that for homes within 100 feet of the roadway centerline, the daytime standards are exceeded by approximately 2 dBA. However, for most homes which are 150 to 200 feet from the roadway centerline, the predicted traffic noise levels are at or below the daytime noise standards for residential land uses.

Each of these tree areas were approximately 2000 feet wide (east to west) and approximately 500 feet deep (north to south). While no specific studies on the shielding effects of these trees have been made, it can be assumed that each of these tree barriers provided no more shielding than a solid barrier 20 feet in height. This is consistent with empirical data that a 100 foot band of dense tree cover would have provided up to 3 dBA attenuation of traffic noise, so that a 500 foot band could provide up to 15 dBA attenuation, which is the maximum provided by a 20 foot barrier (in close proximity to the barrier). However, since traffic along US 169 constitutes a line source, i.e. noise emanates from along the entire highway, these tree barriers only provided partial shielding of the highway. Because of the nature of noise propagation and depending on the positions of future buildings within VGCC, homes south of Dean's Lake may be exposed to noise from portions of US 169 that were previously shielded by the trees. However, this potential exposure was investigated and found to be generally less than 1 dBA, as shown in TABLE 25-6-0PTION A. It is commonly accepted that the average listener can detect a 3 dBA change in sound levels. Therefore, it is doubtful if this change would generate much impact. City of Shakopee Valley Green Corporate Center 2003 AUAR Page - 46 The impact of removing these trees was simulated assuming that each tree band was equivalent to a solid 20 foot high noise barrier along the east/west extent of the trees. Residential receptor sites along the south edge of Dean Lake were evaluated. The assumed tree barriers and residential receptor sites are shown in FIGURE 19. The results of this simulation with and without the simulated trees and therefore the difference in noise attributed to the trees are presented in TABLE 25-6-0PTION A. TABLE 25-6-0PTION A rsic- based on traffic counts from Julv. 2000 AAURl SIMULATED IMPACT OF TREE REMOVAL ON NOISE LEVEL FROM US 169 at Residential Area North of CSAH 16 - (dBA) Site Trees No Trees Impact 1 45.0 45.8 0.8 2 44.3 45.4 1.1 3 43.6 44.5 0.9 4 44.0 44.8 0.8 5 42.9 43.5 0.6 It can be seen that the maximum impact of just over 1 dBA is expected to occur at Receptor Site #4 which is closest to Dean's Lake. However, the predicted noise levels at the sites from US 169, which is approximately 3000 feet to the north, is close to a typical urban ambient noise level that is caused by noise sources within a several mile radius of any given location. Therefore, while some impact may be noted with the removal of trees, the level of impact is expected to be generally less than 1 dBA. It should also be noted that the placement of buildings on the project site could provide some shielding of noise fromUS 169 in lieu of the trees that were removed, and could be more effective because of their solid construction. However, without a specific building plan, no estimate of potential shielding from future buildings can be made at this time. Based upon the analysis of traffic noise levels and the impact of tree removal from the project site, the project is not expected to have a significant adverse impact on noise levels at either future commercial areas adjacent to critical intersections or at the residential area adjacent to CSAH 16 and south of Dean Lake.26 The preceding noise analysis for the commercial portion of the site uses the Traffic Volumes and Patterns included in the July, 2000 AUAR. Option B (New analysis provided from information based on the site plan) Construction Impacts: Similar impacts are anticipated as with Option A. Dust, noise and vibration will be associated with the normal grading and construction activities. The following measures to minimize noise anddust emissions will be incorporated into the construction procedures for the prgject: . All internal combustion motors will be fitted with mufflers and other noise control equipment as specified by the manufacturer. Once the project is completed and operational, no unusual dust, odors or noise will be generated except that associated with mechanical equipment located on or adjacent to some of the buildings within the project. Traffic Impacts in Commercial Portion - Given that the revised scope of the project reflects a reduction in traffic generation, it is concluded that the potential impacts will be less than previously determined and accepted in the previous AUAR. Impacts on Residential Receptor Sites - The revised project scope to reduce the business park and increase the residential housing will include the placement of hOjlses closer to surrounding adjacent roadways. A new investigation of the potential noise impacts is necessary and provided. 26 David Braslau, David Braslau and Associates city of Shako pee Valley Green Corporate Center 2003 AUAR Page - 47 Noise Terminology dB(A) - A unit of sound level expressed in decibels (dB) and A-weighted. DECIBEL - A unit of sound pressure level, abbreviated as "dB". dBA A special weighting of sound pressure that approximates human hearing. dBLin - Raw levels of sound pressure measure as recorded by the equipment. LIO - Lso - The sound level, expressed in dBA, which was exceeded 10 percent (or 50 percent) of the time in a 1 hour screening. Ldn - Average day-night level which includes a 10 dB weighting factor for night-time readings to allow for increased sensitivity to noise during the night-time hours. Ldn is equal to the Leq (time weighted average) when applied to day-time hours only (7 am to 10 pm) activities. NAC - Refers to "NOISE AREA CLASSIFICATION" as dermed in the Minnesota Rules Category 2 refers to COMMERCIAL. Category 3.refers to INDUSTRIAL. Traffic Noise Impacts Minnesota Pollution Control Agency (MPCA) noise standards for residential and commercial land uses are listed in TABLE 25-1-0PTION B. The residential area most likely impacted by noise from immediately adjacent roadways carrying project traffic are those north ofCSAH 16 and south of Dean Lake. Areas adjacent to the critical intersections serving the project are most likely to be developed as commercial land uses if such development occurs. It should be noted that under an amendment to Minn. Stat. 9116.07, subd. 2a, these standards no longer apply to roadways except in the cities of Minneapolis and St. Paul. A traffic noise impact analysis is still included in this AUAR using the MPCA standards as planning guidelines although they will be referred to as "standards".

Although there are residential units located with the proposed development, the entire area is zoned commercial. For the purpose of this study, three receptor sites were chosen in the proposed residential area. . Receptor No.1: Located on the western limits of the residential area; . Receptor No.2: Located on the northern limits of the residential area, east of the Dean Lake Boulevard access; . Receptor No.3: Located on the southern' limits of the residential area, east of the proposed CSAH 16 access. City of Shakopee Valley Green Corporate Center 2003 AUAR Page - 48 I Traffic noise levels have been analyzed for the PM Peak Hour which represents the worst case daytime noise levels for comparison with the MPCA daytime noise standards and estimated AM peak hour, 6:00-7:00 am. Noise levels were analyzed at the receptor sites in the residential area north ofCSAR 16 and south of Dean's Lake. The STAMINA 2.0 highway noise model was used with the estimated Build traffic developed in Question 21 for the year 2020. An average speed of 65 mph along state highways, 45 mph along county roadways and 30 mph along private streets was utilized. A vehicle mix of 5.9% medium trucks and 4.1 % heavy trucks was assumed on all of the roadways. The projected LlO and Lso noise levels at receptor sites are presented in TABLE 25-2-0PTION B. TABLE 25-2-0PTION B Stamina Noise Modeling Results (2020 Build) Daytime Nighttime LlO L50 LlO '" L50 No Barriers Receptor 1 62 60 60 58 Receptor 2 63 61 62 59 Receptor 3 65 60 64 59 Buildings as Barriers Receptor 1 61 59 59 57 Receptor 2 62 59 61 58 Receptor 3 65 60 64 59 The modeling results demonstrate that given the full construction with traffic in the design year 2020, and the projected traffic volumes of the revised layout; daytime and nighttime noise levels will not exceed the MPCA noise limits for commercial receptor sites. Traffic,Noise Impacts in the Commercial Areas - Daytime (PM Peak Hour): Similar impacts are anticipated; impacts would be slightly reduced due to the reduction in generated traffic. Traffic Noise Impacts in the Residential Areas- Daytime (PM Peak Hour): Similar impacts are anticipated. No residential units are to be located within 200-ft of any roadway centerline; therefore, the residential receptors would be within the MPCA Category. 1 standards. This are is currently zoned commercial/business park and as such, the above analysis meets the noise standards for this area. However, a change in zoning of this area from commercial to residential will lower the noise threshold standards. Therefore, the traffic associated with the surrounding rmids and the development have the potential to exceed these noise threshold standards. As part of the development, mitigation measures for the noise will be included. 25. SENSITIVE RESOURCES 25. Sensitive Resources a. Archeological, historical, or architectural resources? 0 Yes L'[?l No For an AUAR, contact with the State Historic Preservation Office is required to determine whether there are areas of potential impacts to these resources. Ifany exist, an appropriate site survey of high probability areas is needed to address the issue in more detail. The mitigation plan must include mitigation for any impacts identified. Option A and B (Information from the 2000 AUAR with minor revisions) A Phase I Archeological Survey was completed by The 106 Group for the development site. The report indicates that no archeological sites were located within the VGCC project area and that there is little City of Shakopee Valley Green Corporate Center 2003 AUAR Page - 49 . probab~lity that the area contains identified archaeological resources of historical significance. This report is contained within APPENDIX E. b. Prime or unique farmlands? 0 Yes 181 No The extent of conversion of existing farmlands anticipated in the AUAR should be described. If any farmland will be preserved by special protection programs, this should be discussed Option A and B (Information from the 2000 AUAR with minor revisions) The project does not contain any prime or unique farmlands. Past land uses have included some agricultural use, mainly in the north and west portions of the project site. Those areas are considered fair for agricultural uses consisting of Dakota Loam and Copas Silt Loam. Both soil types have good drainage, although drainage can be restricted by bedrock in areas of the Copas Silt Loam. The majority of the site is comprised of sandy, droughty soils on the Dune Lake, Hubbard, Isanti, and Zimmerman series with marshy soils located along the west edge of Dean's Lake. The southeast portion of the study area is comprised of stoney land and terrace escarpments. c. Designated parks, recreation area, or trails? 0 Yes 181 No Ifdevelopment of the AUAR will interfere or change the use of any existing such resource, this should be described in the A UAR. The RGU may also want to discuss under this item any proposed parks, recreation areas, or trails to be developed in conjunction with development of the AUAR area. Option A and B (Information from the 2000 AUAR with minor revisions) The concept plan illustrated in FIGURE 3a and 4 and described in the Community Value Statementfor Valley Greim Development, West Dean's lake Area (see the APPENDIX C) proposes a concept for natural open space and trails. Throughout VGCC there is proposed to be areas designated as 'Natural Open Space Conservation Area'. The Community Value Stdtement recommends that easements be granted to the City which will allow the construction of trails and recreational use. Both options include the "Natural Open Space Conservation Area". Proposed development of the project site will not affect any existing public parks, recreation areas or trails. A portion of the City's Comprehensive Park and Trail Plan is shown on FIGURE 20. Dean's Lake is classified as a shallow natural environment lake. Much of the land directly around Dean's Lake consists of marsh and peat muck soils. d. Scenic views and vistas? 0 Yes 181 No Any impacts on such resources present in the AUAR should be addressed. This would include both direct physical impacts andimpacts on visual quality or integrity. "EA W Guidelines: contains a list of possible scenic resources (page 20). Neither Option A or B would affect any designate scenic views or vistas. City of Shako pee Valley Green Corporate Center 2003 AUAR Page - 50 l 26. VISUAL IMPACTS 26. Adverse visual impacts. If any non-routine visual impacts would occur from the anticipated development covered by the MUSA review, this should be discussed here along with appropriate mitigation. Option A (Information from the 2000 AUAR) Proposed development will alter the site appearance from a dormant, pre-graded development site to that of a business park setting with a medium density residential buffer area between the residential area to the south and the business park. The 1.2 acres of replacement wetland has started to exhibit acceptable characteristics of wetlands. An additional 1.29 acres of wetland will be filled with 2.58 acres of wetland created as mitigation. Final site occupancy for the proposed development should include planting trees, shrubs and other landscaping, at the individual lot owner's discretion. The replacement wetland and buffer areas should be seeded with a mix of native flora to enhance the natural beauty of the area. Some . local residents have voiced protest over the removal of several trees from the proj ect area. Their concerns involve the fact that US 169 is now visible from their homes. Several trees were removed from the north border of the area. A portion of these were removed in compliance with the City of Shako pee's Oak Wilt Suppression Program. The perceived adverse visual impacts will be mitigated somewhat with the location of buildings and the associated landscaping for this development Option B (Information from the site plan) Proposed development will alter the site appearance from a dormant, pre-graded development site to that of a business park setting with a medium density residential buffer area between the residential area to the south and the business park. More medium density area will be present than provided in Option A. The 1.2 acres of replacement wetland has started to exhibit acceptable characteristics ofwetlands. An additional 1.29 acres of wetland will be filled with 2.58 acres of wetland created as mitigation. Final site occupancy for the proposed development will include planting trees, shrubs and other landscaping, at the individual lot owner's discretion. The replacement wetland and buffer areas will be seeded with a mix of native flora to enhance the natural beauty of the area. The landscaping will also meet City Standards, including the Shoreland Ordinance. 27. COMPATABlllTY WITH PLANS 27. Compatibility with Plans. The A UAR must include a statement of certification from the RGU that its comprehensive plan. complies with the requirements set out at 4410.3610. subpart 1. The AUAR document should discuss the proposed A UAR area development in the context of the comprehensive plan. If this has not been done as part of the responses to items 6,9,19,22, and others, it must be addressed here; a briefsynopsis should be presented here if the material has been presented in detail under other items. Necessary amendments to comprehensive plan elements to allow for any of the development scenarios should be noted. If there are any management plans of any other local, state, or federal agencies applicable to the A UAR area, the document must discuss the compatibility of the plan with the various development scenarios studied, with emphasis on any incompatible elements. Option A and B (New information) Both development options will require the land use to be reguided within the project area and rezoning to occur. The land use reguiding will need to be approved by the City Council and the Metropolitan Council prior to re-zoning approval. This is required prior to fmal approval of either development option. Both development scenarios are also required to conform to the following plans: City of Shako pee Valley Green Corporate Center 2003 A UAR Page - 51 . City of Shakopee's Comprehensive Stormwater Management Plan . City of Shakopee's Transportation Plan 28. IMPACT ON INFRASTRUCTURE AND PUBLIC SERVICES 28. Impact on infrastructure and public services. This item should first of all summarize information on physical infrastructure presented under items (such as 6, 18, 19 and 22). Other major infrastructure or public services not covered under other items should be discussed as well -- this includes major social services such as schools, police, fire, etc. The RGU must be careful to include project-associated infrastructure as an explicit part of the A UAR review if it is to exempt from project-specific review in the future. Option A and B (Information from the 2000 AUAR with revisions and additions) Construction of either option requires the extension of sanitary sewer lines and water mains from the City of Shakopee. Negative impacts on the City's infrastructure are not anticipated. The project site was included in the MUSA expansion granted to the City of Shakopee by the Metropolitan Council. Approval of this expansion required a comprehensive study and proof of the City's ability to serve this area with adequate water and sanitary sewer service. Other public services such as fIre and police would be provided by the City of Shakopee. County Road 83 offers a direct link between the City and the VGCC. Some indirect impacts in the surrounding residential areas may occur because of the employment opportunities that would be created by the proposed development. As compared to the 2000 AUAR where no impact on the school district was anticipated, both Option A and B include multi-family housing. In general, the type oftownhomes that are planned to be constructed generally do not attract families with school-aged children. However, it is anticipated that some children will be present within the development, with more children anticipated as part of Option B than A. As part of this AUAR process, the AUAR will be sent to the School District for comment. - . 29. CUMULATIVE IMPACTS 29. Related Developments; Cumulative impacts. This item does not require a response for an A UAR since the entire AUAR process deals with cumulative impacts from related developments within the AUAR area. 30. OTHER POTENTIAL ENVIRONMENTAL IMPACTS 30. Other Potential Environmental Impacts. If applicable, this item should be answered as requested in the EA W form. Two other AUAR's have been completed for this project. The fIrst AUAR was completed in 2000 and assumed the site would be developed completely into Business Park. The second AUAR was completed in 2002 and was a supplement to the 2000 AUAR. The second AUAR included Business Park and Medium- Density Residential. The development scenario from the 2002 AUAR is presented here as Option A. The concept plan for Option B was recently developed and is thus included in this revised AUAR. Since these AUAR's have been prepared for the site, it is believed that all known potential environmental impacts have been identifIed.

The RGU may answer this question as asked by the form, or instead may choose to provide andExecutive Summary to the document that basically covers the same information. Either way, the major emphasis should be on: potentially significant impacts, the differences in impacts between major development scenarios, and the proposed mitigation An Executive Summary has been provided at the beginning of this document.

'J ~ As you are aware, \ySB & Associates has been working with the City of Shako pee and Valley Green \..::: Business Park on the proposed CSAH 83 / CSAH 16 improvements for the past two years. We have C:} recently completed an analysis of revised traffic numbers based on information provided by your "'\ transportation consultant (SRF Consulting Group). You proVided direction at our August 23, 1999, ~"';-"-.'.- meeting to meet with SRF and review the trip generation and distribution assurn,ptions for the proj ect f] and to come to agreement on the traffic numbers. This has been completed, and the memo from SRF , . dated October 22, 1999, is the result of that meeting and agreement (attached). 'to; .: , ~ ~ ~ Based on the revised traffic numbers, as outlined in the October 22; 1999, SRF memorandum, we .~'.'; J have analyzed the proposed. c.orridor and intersections using. the SYNCHRO software. A table outlining the analysis results, as well as the analysis worksheets, is attached to this letter. ! . The results of the analysis indicate that the individual intersections in the year 2017 will all be , operating at level of.s'ervice (LOS) D or better during the AM and. PM peak hour. The overall 'J arterial analysis also indicates that the entire corridor would also be operating at an LOS D or better b, for both northbound and southbound traffic during-the AM aild PM peak hours. However, with the coordinated system, the arterial LOS at specific intersections in some cases is at an E, and in one t. "'f case at the north TH 169 ramp intersection an F during both the AM and PM peak hours. It appears ! "nl 'c J that this is primarily a result of the amount of green time allocated for each phase. To accommodate the coordination ofCSAH 83, the amount of green time allocated for the northbound and southbound ~ movements for specific cycle lengths deters from the amount. of green time allocated for the side ...J streets, therefore producing unsatisfactory levels of service (or those movements. { .... '1 ~e length of queue was also reviewed as part oftrus analysis. It was found that the westbound right .:;-- turn lane and the southbound left turn lane at the Valley Green Corporate Center site . entrance/CSAH 16 (west) has the potential for backing up into their respective through lanes. rei ..\ t..l In.ft'astructure Engineers Planners EQUAL OPPORTUNITY EMPLOYER F:\WPWIN\I063.21\1I 1999.bl.wpd . '} '.. J .. I , I '~1 Mr. Brad Larson j I Scott County Highway Department Jordan, MN j December 2, 1999 I Page 2 ~J ' It should be noted that the traffic volume information provided and the analysis that was conducted' ~.} is for a 20-year traffic forecast. These traffic volumes are based on significantly conservative assumptions with respect to the development of the Valley Green Corporate Center site, as well as the adjacent development in the area and background traffic growth along the corridor. Considering " f this and the results of the analysis, it is our conclusion that the concept plan with the proposed ! geometries would provide the necessary capacity to accommodate these 'developments now and in ; oj , 'the future. The traffic signal systems along the corridor can be adjusted with timirig modifications , 1 as the traffic along the corridor increases. In addition, it is our experience that as congestion occurs ,...." . along a corridor, vehicles will tend to use alternate, less congested routes to and from a site. ~ J Therefore, the proposed geometrics of these roadways and the realignment of CSAH 16 will provide ~l the required capacity now and in the future. t." It is our understanding from our conversations with you and Brian Sorenson, and your conversations (1 with the City of Shakopee, that the County is in favor of the proposed realignment of CSAH 16 as '.} an overall transportation improvement for this area. The, alignment of CSAH 16 (east) with the proposed 17th A venue to parallel TH 169 on the south side makes sense as a transportation improvement for the entire region. We do understand that there are additional issues related to this with respect tathe jurisdiction of 17th Avenue to the west ofCSAH 83. However, at this time, we (J are not looking for your concurrence on that aspect of the plan. That is an issue that can be addressed once it is concurred that the realignment of these roadways makes sense and the '\;.... geometrics as proposed would adequately handle the anticipated traffic volumes on CSAH 83. :] As you are aware, the improvements of CSAH 83/ CSAH 16 has been a proposal seen by the 1 ".' j County over the past two years. The following are key milestones which have occurred in that time ., frame. / ' October, 1997 'Feasibility report cdmpleted by Valley Green and submitted t6 the i!

As requested by WSB Associates, we have prepared an additional trip t.j' generation estimate alternative for the proposed Valley Green development assuming an "Office Service" land use for sites numbered 9 - 14. The original trip generation estimate in the rl June 8th memorandum assumed a "Business Park" land use for these sites. The "Office Service" i. J land' use was calculated by WSB Associates assuming 25 percent office and 75 percent warehouse determined from WSB from a review of similar uses in the area. The "Office Service" land use is similar to the "BUsiness Park" use in the 1997 ITE Trip Generation Reports, but results in a lower trip generation estimate. to.., .~ , ':1 ':.'J ~i:jf ReSULTS f>>} The volumes resulting from both the original SRF trip generation estimates and from the trip ; r.. <1 generation estimates using the WSB "Office Service" land use are displayed in the attached Figures 1 and 2 respectively. As shown in the attached figures, the southbound a.m. left-turn j volumes at the intersection of CSAH 83 and the Site Driveway do not change between the two i " j alternatives. The p.m. peak left-turn volumes drop by less than 100 vehicles per hour. '.-1 ....,: ~ j It should be pointed out that the volumes displayed in Figure 1 include a diversion of 'LJ approximately 35 percent of the southbound left-turns from the CSAH 83/Site Driveway , , intersection to the County Road 16/Site Driveway intersection.

Driveway intersections and rerouting the traffic from theover-capaci~ site driveway on l.:.. CSAH 83 to the under-capacity driveway on County Road 16. The reserve capacity was 'j calculated at each intersection using critica1lane volumes. The diversion was only applied to the southbound left-turning traffic during the a.m. peak hour. i The volumes displayed in Figure 2 include a diversion of approximately 25 percent'between the \ \~_.} .tWO site driveway intersections using the same methodology. Both diversions were compared to r i the proposed site plan in order to detennine if the percentages were reasonable. The proposed ~J site plan displays commercial land . uses nearest the access onto CSAH 83, office/warehouse to the east, and office towers in the northeast comer of the site. Therefore,' diversion to the alternate fJ south access is reasonable for familiar users (such as office employees). 1l1e method used to ~< determine the amount of diversion is based on a simple analysis based on intersection capacity. ~;.: If a more detailed analysis results in available capacity at the CSAH 83/Site Driveway ,1 intersection, fewer trips would divert. The recent roadway layout was also reviewed during the meeting with WSB A,ssociates. The most critical queuing location is the southbound left-turns at the CSAH83/Site Driveway intersection. Additional storage for the left-turn vehicles could be obtained by providing a t } continuous left-turn lane starting from the CSAH 83/Shakopee bypass south ramp intersection, . tapering to a second left-turn lane. This could be accomplished through proper. striping and signing) but would require acceptance by MnlDOT due to the proximity to the trunk highway Cl ramp intersection. Special traffic signal timing operation may also be used to reduce left-turn ;.,.t queues. ',.,) , The intersection of County Road 16 and the Site Driveway should be periodically reviewed for traffic signal w.arrants. The traffic diversion percentages assume a traffic signal installed by 2017 in order to provide the reserve capacity required for operation 'of the CSAH 83/Site .1' Driveway intersection. [:,j t::;{.~ .'12;.:4' ; CONCLUSIONS ; j ,; .) . The proposed Valley Green Corporate Center is a substantial amount of development and i will result in approximately 32,000 to 40,000 additional weekday trips. I 1':'1 . The background growth rate of 15 percent per year used by WSB is reasonable for the area ..-.~.- ~A surrounding the proposed development. f<l . The proposed project location south of TH 169 in an area without many parallel routes causes . : 5S percent of the site-generated traffic to travel to/from the north. This creates left-turn ":.'il iJ volumes into the site from the north during the a.m. peak hour of 1,300 - 1,600 vehicles. ;.> \ ~;"',} o. 0(.T-22-99 FR I 14: 54 SRF FAX NO. 4752429 1'.

The intersection of County Road 16 should be periodically monitored for traffic signal ~ warrants due to the increase in volumes on County Road 16 with the construction of 17th Street and the diversion of traffic assumed from the Site Driveway on CSAH 83.

I i TRAFFIC FORECASTS Traffic forecasts were developed for the year 2017 with the proposed Valley Green Corporate Center in place. The 2017 was chosen in ofder to be consistent with the traffic forecasts presented in the ADAR. Forecast Process The following process was used to complete the 2017 traffic forecasts. 1. Collect 2017 a.m. and p.m. peak hour turn movements forecasts from the AUAR document. '.. 2. Remove the trips generated by Valley Green Corporate Center based on the trip generation estimates and trip distribution percentages developed by SRF Consulting" Group, Inc. This step resulted 'in 2017 base volumes without Valley Green Corporate Center. 3. Add trips to and from the current develo,pment plan to the base 2017 volumes from step 2) to 'develop 2017 build volumes for each peak period.' This is done assuming no capacity constraints at the key inters~ctions. ! Trip Generation " The a.m. and p.m. peak hout and daily development trip generation projections have been established using the Institute of Transportation Engineers' (lTE) Trip Generation, 6th Edition.

The trip generation percentages are as follows: . 35 percent to/from the east on T.H. 169 . 18 percent to/from the east on County Road 16 . 12 percent to/from the south on CSAH 83 . 10 percent to/from the west on the future 17th Avenue . 1 0 percent to/from the west on T .H. 169 . 5 percent to/from the west on County Road 16 . 10 percent to/from the north on CSAH 83 J A difference in assigning the development trips occurred due to the current assumption that the development access on County Road 16 east'ofCSAH 83 will bea right inlright out only access. ,It appears that the original forecasts assumed a full access intersection along this section of roadway. .

The current proposal for Valley Green Corporate Center is estimated to ' i generate net totals of 2,338 a.m. peak hour trips, 2,647 p.rn. peak. hour trips, and 22,701 daily trips. All of these totals are less than the trip generation JJ estimates used in the AUAR analysis. · Using the updated 2017 traffic volumes results in slightly hnproved l intersection operations assuming the same signal timing and phasing used in ! the AUAR analysis. This analysis assumed a 150 second cycle length for all intersections. · Using a 120 second cycle length results in improved level of service an ,- 1 queuing results for the corridor. We recommend the consideration of cycle J' lengths shorter than 150 seconds for this corridor. We suggest that as volumes .. . increase, the corridor be analyzed to determine the best overall cycle length and signal timing settings. B,. ":": i.:;~, ' 'J ,0\ ~.., .' " fJ.'

We also used trip generation estimates for the Valley Green Corporate Center presented by SRF Consulting Group. Inc. dated June 8, 1999. PROPOSED DEVELOPMENT The current development plan consists of the land uses and sizes shown in Table 1. These land uses and sizes were used to estimate tbe traffic volumes presented in this report.

Remove the trips generated by Valley Green Corporate Center based on the trip , generation estimates and trip distribution percentages developed by SRF Consulting Group, Inc. This step resulted in 2017 base volumes without Valley Green Corporate Center. 3. Add trips to and from the current deVelopment plan to the base 2017 volumes from , " , ( step 2) to develop 2017 build volumes for each peak period. This is done assuming no capacity constraints at the key intersections.

(:onservation Development Planning City of Shako pee Community Value Statement for Valley Green Development I West Deans lake Area Date: November 27, 20001 (Updated January 4,2002) From: Jeff Schoen bauer, Vice President Brauer & Associates, Ltd. Conse'rvation Development Planning Consultant to the City of Shakopee Overview The initiative to undertake a collaborative planning process between the city and the developer for the Valley Green , development area was an outgrowth of the Deans Lake Area Master Pla.n completed by the city in July of 2001. From the city's perspective, the objective defined in the master plan was to maximize the community values associated with the development of this area to exceed that which is already provided under city ordinance. The key values being sought include: ~ Maintaining an ecological protection zone and adjoining buffer zone along the lakeshore. ~ Preserving as much natural open space along the west side of the lake as feasible. ~ Providing a linear trail corridor along the west side of the lake that links to other trails defined under the master plan. ~ Expanding natural open spaces and trails into and through the development area in a meaningful way. ~ Using ecologically-based approaches to stormwater management ~ Reducing the extent of impervious surface to the extent possible. ~ Establishing an ecological stewardship program for natural areas. City Staff and Consultant Role in the Project City staff's role in the project was to provide information about city development requirements, standards, procedures, and input on a variety of development issues affecting the development's final form. Under the conservation development approach, city staff also took a proactive role in discussing development issues so that the developer had a greater sense of staff's concerns about specific issues. This proved valuable to the city's consultant and the developer as the development plan emerged. The city's consultant, Brauer & Associates, ltd. (in collaboration with Applied Ecological Services, Inc.), worked with the developer on behalf of the city to prepare a development plan consistent with the conservation development approach to planning as defined under the Deans Lake Master Plan. Importantly, Brauer's express role was to maximize the community values derived from the development in a manner that was consistent with the Deans lake Master Plan, as well as the broader. vision for the community as a high quality place to live, work, and recreate. Throughout the planning process, the Brauer team, in concert with staff, strove to achieve the highest possible outcome within the context of an economically-viable development Planning Context From a historical perspective, much debate has occurred in recent years about the development plans for the Valley Green develapment Area, Ultimately, a preliminary plat for the property was accepted by the City Council, which allows the current land owner to move farward with development of the property in accordance,with city requirements. In general, the development proposed by the current owner would be a cammercial/business park development consistent with ather past developments within the city, If the property is not sold to another party, it would be expected that a "piecemeal" appraach would be taken by the current land owner until the site is fully developed. Brauer & Associates, ltd, 1 I , . Conservation Development Planning City of Shakopee: , i '. Since the time that the preliminary plat was approved, Ryan Companies US, Inc. (Ryan) has expressed an interest in purchasing' and developing the site from the current land owner, under the assumption that a, favorable development plan could be reached with the city through a collaborative planning process. Recognizing the challenges associated with this property in the past, Ryan agreed to work collaboratively with the city in preparing a development plan that maximizes community values while still being an economically~viable development The pretense being that a win-win development solution could be found. r ,', if the two parties worked together throughout the planning process. Ryan also agreed to participate in this process because the k company felt that building a strong level of trust with the city and the neighborhood was necessary if a successful plan was to f.",:,: emerge - especially given the history of the site. The forthcoming community value statement focuses on the values that the city would realize from the development plan being prepared by Ryan to the city for consideration. Note that for comparison purposes, the accepted preliminary plat for Valley Green Corporate Center, ofteri referred to as the Albinson plan, is used to illustrate the key differences between what is already [ approved and what might be achieved if the Ryan plan is ultimately approved in lieu of the Albinson plan. L Comparison of Development Plans f",' I t : '1;.: For comparison purposes, three development plans have been considered, including: ~ Valley Green Preliminary Plat Development Plan - represents a development plan associated with the preliminary plat approved by the city. (This is also referred to as the Albinson Plan.) ~ Ryan Residential/Commercial Plan..,.. represents a proposed plan that includes a residential component in addition to the commercial development proposed under the Valley Green Plan. , ~ Ryan Commercial Plan - represents a proposed plan that is all commercial, should the city not accept the residential !

These are accompanied with color graphics that relate to the various land use categories. (Exhibit A 1 should be referred to for these graphics and additional acreage breakdowns.)

Conservation Development Planning City of Shako pee The information presented in the table establishes baseline information about the development and provides pertinent information that is used in the forthcoming summary of community values achieved by the project. Residential Versus Commercial land Use Decision As defined above, one of the development proposals includes a residential component in lieu of commercial/business land '-. uses. This opportunity arose out of the design charrette process (i.e., collaborative design meetings) in which the city's team, led by Brauer, and the developer's team considered various ways to approach land use decisions. From the developer's perspective, the every changing nature of the economy and the land development environment suggests that a residential development could be economically feasible, especially given its location relative to parks, open spaces, and trails. The approved Valley Green, or Albinson, plan, was based on the assumption that the guided land use was the most economically- viable approach and did not pursue adding a residential component to the development From the perspective of the city, Ryan's interest in developing this property presents an opportunity to reconsider past land use decisions if doing so results in favorable outcomes for the city as it strives to maintain a high quality of life in the community, retain its historic character, and foster a strong sense of place in its residential neighborhoods. To this end, there are some compelling reasons for the city to consider this approach, as follows: ~ The Deans lake area is a unique community asset that offers the exact type of living environment people hold in high regard - including nature, trails, open space, parks, convenience to roadway systems, jobs nearby, etc. As defined in Exhibit B, the Deans lake area is one of a limited number of areas within the city that have these qualities. ~ Higher amenity settings, sllch as the Deans lake area, tend to hold-up/enhance property values initially and over time. ~ Greater design flexibility of residential (versus commercial) development provides more opportunity to preserve critical open space and natural resource areas along the lakeshore. ~ A "softer" transition between natural open space/park setting and commercial development can be achieved, which is important in that the relationship of this developmentto the lake affects the character of the entire Deans Lake area. , ~ Encroachment of trucks, cars, and larger structures along the lakefront is precluded, which in turn provides a more pleasant aesthetic setting for p~rk and trail users. The vision as defined in the Deans Lake Master Plan adds strength to this perspective, whereby the master plan seeks to maximize the value of the natural amenities surrounding !Deans Lake by creating a high quality living environment (See Exhibit D.) Under a commercial development scenario adjacent to the lake, the"natural amenities of the area are simply used as a buffer between the lake and larger commercial buildings and parking lots. Recognizing that private land development will likely continue to occur over time around the entire lake, the challenge for the city lies in dire~ing that development to the highest and best use of the land in the context of the larger vision for the community. The challenge for the developer rests in presenting a development plan to the city that is compelling enough to warrant a revision to past land use decisions. The residential/commercial development plan presented by Ryan attempts to achieve this end. Summary of Community Values Achieved Throughout the planning process, the city' team, lead by Brauer, has focused on maximizing community values in a meaningful way. The following summarizes the extent to which the development proposal was able to achieve these ends. To aid in this evaluation, a comparison between Valley Green's approved preliminary plat and the proposed residential/commercial development by Ryan is also provided. Preserve Natural Features. Habitat. Open Space As indicated in the previous table, there is considerable variability between proposals in the number of acres that are defined as conservation areas - which are defined as lands that will remain as natural open space once the development is completed. Even though the overaU acreage of green space between developments is less pronounced, the Ryan plan offers more acres under conservation area designation. This is of considerable importance in that these lands would be included under a conservation easement that would offer perpetual protection from encroachment or other land uses. (Note that the conservation easement would allow for public trails,) As part of the development package, these easements would be legally recorded with the city to ensure their indefinite protection as natural open space. The developer, however, would still be responsible to manage and maintain these lands, as defined under the forthcoming Stewardship Program. The following table provides a comparison of development proposals. Brauer & Associates, ltd, 3 , .

Exhibit D provides an overview of the vegetative plan concept ;.: ~ Maintain Ecological Protection Zone Along lakeshore As defined under the Deans Lake Area Master Plan, protecting the ecologiCal and natural aesthetic qualities of the west r shoreline of Deans lake was of considerable"and justifiable, importance to the community and neighborhood. Under the I existing city ordinance, if the proposed development is of a comm~rcial/business nature, the minimal requirements associated "" with the shoreline include: ...:' ~ 1 SO' structure setback from the ordinary high water mark. (200' under a residential land use.) ~ Visual screening from the lake to a level of 75% opacity during leaf-on conditions. '[' ~ lacking ability to provide visual screening, an additional 150' setback is required, totaling up to 300' from the ordinary high i water mark. l Whereas the Valley Green development plan is obligated to achieve these minimal requirements, applying the opacity f' ordinance does offer some challenges in terms of how that is functionally determined. Under the Ryan development plan, the [ proposed residential development setback from the shoreline is a minimum of 250', This is of considerable importance in that not only is the ordinance exceeded, the additional land adjacent to the lake also provides more area to restore working ! ecological systems that have both an aesthetic and functional value. As part of the development package, the shoreline would f be included under a conservation easement that would be legally recorded with the city.

The level of commitment by the developer to restoring natural areas would be defined as part of the formal development package submitted to the city to ensure consensus on this issue as part of the formal approvals process. Exhibit D provides a cross-section of the intent of the shoreline restoration. Ecologically-Based'Approach to Stormwater Management " Using ecologicallY-9ased approaches to st6rmwater managementto increase levels of infiltration on the site, slow ~he reJea~e rate of stormwater to downstream systems, and improve overall water quality in the process was a major objective for the city's team. Whereas the Valley Green development plan followed standard practices and city standards in this regard, the city's team saw numerous opportunities to take a more ecologically-based approach to stormwater management on the site. Specific opportunities include: .. Using natural systems in lieu of mechanically engineered systems to control stormwater runoff. This includes natural drainage swales, infiltration "rain gardens", and ecologically-based ponding/wetland systems. .. Managing stormwater on-site to avoid the need for off-site stormwater ponding. .. Using natural systems to infiltrate stormwater along the shoreline to reduce flow rates into the lake and maintain very high water qualities that exceeds that which is typically achievable using traditional NURP pond systems. .. Reducing the extent of impervious surface to the extent possible to minimize the need for built stormwater management and conveyance systems. Note that the stormwater management system would be an integral and seamless part of the natural areas, whereby the desired public open space values are achieved at the same time. Exhibit E highlights some of these opportunities in graphic form. The following table provides a comparison of development proposals as it relates to the stormwater management Valley Green Preliminary Plat Ryan Residential/Commercial Plan Public Values Achieved/Flexibility Required Follows typical stormwater management The goal with the stormwater system as Under the Ryan plan, the developer would approach, with significant use of NURP proposed is to. manage stormwater in an , be managing stormwater onsite as part of a ponds, Lacking an interconnected natural ecologically-sound manner tha,t is beneficial larger natural open space system. The public system (as shown on the Ryan plan), to the site and downstream systems, would benefit through an increase in open greater reliance on built storm sewers space and also be assured that stormwater is would be expected - which reduces'the managed in an ecolo.gically-favorable capacity to infiltrate sto.rmwater onsite. manner, The project would also. be an example of how the city can work with the development community to. better manage storm water onsite to. reduce the dependance and cost o.f developing offsite stormwater management systems. Brauer & Associates, Ltd, 5 ! : . Conservation Development Planning City of Shakope~ , Agreement Parameters: Under the agreement framework, the city and developer would continue to collaborate on designing the ecologically-based stormwater management system. Note that city engineering staff would be particularly involved in this F" aspect of the project to ensure that the final plan would meet or exceed all city standards and requirements. Although the i ! design for the system would be collaborative, the developer would ultimately be responsible for the system's final function and i performance once built. Note that under the agreement parameters, the developer would be responsible for all costs associated f: with creating the stormwater management system. The level of commitment by the developer to doing so would be defined as t,: part of the formal development package submitted to the city to ensure consensus on this issue as part of the formal approvals L, process. Exhibit E provides an overview of the stormwater management plan concept. ~., ; ! Maximize Park and Trail Opportunities Consistent with the vision of the Deans Lake Area Master Plan, maximizing park and open space opportunities in this ; development area was a major objective of the city's team. Whereas the Valley Green development plan is obligated to provide { a linear trail along the shoreline, there are few assurances that additional trails would be provided within the developmentarea itself. Although sidewalks and other typeso{trails would have likely been included in the Valley Green development plan, the f; true public values of those amenities is uncertain since they would not be located in a defined park area or natural open space i that connects to the larger system. Under the Ryan Plan, a looped core trail system would be integrated into the natural open space conservation area that runs through the development This loop would connect directly to the linear trail along the shoreline, which then links directly to the larger trail system proposed under the Deans Lake Area Master Plan. t f With respect to parks, both development scenarios include the 15.80 acres of park land and park dedication fund commitments i defined under the Valley Green preliminary plat. Each also includes the 150' shoreline setback area and other adjoining open spaces. From that point, however, the differences are substantial in that all of the land area previously defined as conservation r areas under the Ryan plan would be open space that could be enjoyed by the public via trails and visually as one drives through { the development (See Exhibit O.)The following table provides a comparison of development proposals as it relates to the parks and trails. f' Valley Green Preliminary Plat Ryan Residential/Commercial Plan Public Values Achieved/Flexibility Required Parks and open space land totals 28.90 Parks and open space land totals 64.86 Considerably more miles of trails are r acres (as defined on page 4). acres (as defined on page 4). provided under the Ryan plan.

Exhibit 0 provides an overview of the trail system within the development. The developer would be responsible to connect these core trails to individual development sites'as they are developed. Note that under the agreement parameters, the developer would be responsible for i all development costs associated with the park and trail system considered above. The developer would also remain the owner 1 of the land and be responsible for long-term maintenance of the trails. (The city would be assured public access to the trails l through a legal agreement.) f' Ecological and Ornamental landscape Stewardship Program To ensure the long-term vitality and health of the natural ecological systems within the conservation easements, parks, and natural areas, the developer has agreed to create and implement a stewardship program. Although the City of Shakopee does not currently have such a program, there are numerous models that can be used as a basis for developing a program for this specific site. Since this is new to the city and developer, development of the program would be undertaken jointly as part of a continued collaboration on the project. Brauer & Associates, ltd. 6 . Conservation bevelopment Planning City of Shakopee " .., Specific agreement parameters most often associated with this type of program include: . Initial restoration of the natural systems contained within the conservation easements and defined natural areas. The developer would agree to complete this work as part of the site development and in accordance with the Stewardship Program's specifications. The city would work with the developer to ensure that methods used are consistent with the city's expectations. Note that a word of caution is required with respect to wetland systems associated with Deans Lake. The practicality of restoring these areas requires additional evaluation since it is uncertain as to how effective restoration of these areas can be given the changes that have occurred over time in lake levels and the ecological systems affected by those changes. >' ,. Year-to-year management of natural areas located within the conservation easements and natural areas. This includes maintenance of the ecologically-based stormwater management system to ensure it functions properly. In addition to the stewardship of natural systems, the developer has also agreed to manage and maintain all ornamental landscapes throughout the site. This would include landscaping that is either on a specific piece of property as well as that is found within the public rights-oF-ways. The following table provides a comparison of development proposals as it relates to the , '". ecological stewardship.

Likely to be little ongoing commitment to would be set up by the developer. ecological stewardship, other than the initial restoration of the site during development Agreement Parameters: Inasmuch as maintaining the ornamental landscape is common place, establishing a stewardship program for the natural areas within the development is ofequal importance. Under the agreement framework with Ryan, a stewardship program would be prepared and implemented as part of the development package. This would include a legal agreement with the city that would obligate the developer to long-term financial support of the program. The city's role under the agreement would be limited to periodic oversight to erisure that the plan is being appropriately implemented. Exhibit F provides an example of a legal agreement between the city and the developer for natural areas. This agreement would be expanded to cover ornamental landscapes as well. An overview of the potential costs that would be incurred by the developer for implementing a natural area stewardship program is also provided.

Through collaboration and candid discussions prior to formal submittal, the prospects for arriving at a development plan that will offer high community values while being economically-viable is considerably enhanced. The concept review phase includes: I 1) Meetingwith local neighborhood group to review development plan and receive feedback. l 2) Meeting with Planning Commission to review development plan and address pertinent issues and concerns. Although a , formal vote will not be taken, candid feedback from members is desired. l 3) Meeting with City Council to review development plan and address pertinent issues and concerns. Again, no formal vote will '. be taken, but candid feedback from members is desired. At the end of the concept review, the city's and developer's teams will address all pertinent issues and concerns and determine f " how the project should move forward. Assuming that the project has merit after the concept review phase, the developer will , prepare a formal submittal to the city for the project. As previously defined, this would include continued collaboration r between the city and the developer to ensure that the agreements made in principle are actually realized as part of the formal development package. (Note that city staff has prepared a possible timeline for the formal approvals process that is included in \ the concept review package.) City Team Role in Refining the Development Package f , As defined above under the agreement parameters, the city's team would have a continuing role in planning and designing the r development through subsequent phases. This continued involvement provides the city with greater assurance that the iO-..... development agreement proposed under this concept review and in formal development submittals yet to come are adhered to and that the city's interests as set forth under the agreements are protected. ' With respect to professional fees, the developer has agreed in principle to set aside funding in an escrow account to cover future costs incurred by the city for consultants working on its behalf on the items listed under the agreement parameters previously defined. The extent and terms of this agreement would be defined as part of the formal approvals process to protect the interests of the city and the developer. Brauer & Associates, Ltd. 8 .' :Conservation Development Planning City of Shako pee Summary Statement Through the collaborative effort between the city and developer, the development plan presented here offers the city the opportunity to achieve higher community values than the previously approved Albinson plan. The collaborative process also gives the city an opportunity to revisit previous land use decisions and determine the land use option that best serves its interests in maintaining a high quality of life in the community. Through each teams' recognition and respect for each others objectives, concerns, and perspectives, a plan emerged that is believed to capture the essence of the conservation approach to development. This was done in spite of the fact that the site itself was challenging and that both restraint and flexibility were needed to reach an agreeable and successful conclusion; From the perspective of the consultant working on behalf of the city, a very reasonable and responsible balance between ecology, culture, and economy has been reached for this site. It is our opinion that each party worked together in good faith and that a superior development proposal resulted for consideration by the Planning Commission and City Council. IT">' .;,\, I,:" ..

The table is provided to define the potential magnitude of investment needed to achieve desired ecological objectives. Note that since a technical evaluation of the site has not been completed, the costs shown. are typical averages on a per acre basis. Actual costs will likely vary, perhaps even considerably, as the final design for natural areas is completed for the project.

The developer would cover these costs directly at the time of development Establishing the ornamental landscape and streetscape would also be the responsibility of the developer at the time of development. ~ Developer establishes an endowment fund for restoring the remaining natural areas across the site and for ongoing m,aintenance of all natural areas included in the development area. This would be expanded to include the ornamental landscape as well. Brauer & Associates, ltd. 1 . Con-servation Development Planning City of Shakopee There are two funding options for the endowment fund: 1) Developer provides an initial contribution to the fund. The interest from this principal investment will be used for year to f' year stewardship activities, minus 10 percent which is reinvested in the fund to build it up over time as a hedge against f. int1ation and unknown costs. 2) Developer creates an association of homeowners and businesses that make yearly contributions to the fund.. 90% of the r... '. proceeds would be used for the year's activities, with 10% being invested into the capital fund to again build it upover f time as a hedge against inflation and unknown costs. , In all likelihood, a combination of the two funding options is expected. The actual amount of the contributions required for the i, fund would be defined as part of the final developer's agreement with the city for the project once ,a final development plan is ' completed. It is recommended that the agreement between the city and the developer be formalized as part of the final " development package so that it is part of the formal approvals process. Note also that in some cases, the city has also i contributed to this fund as part of an overall agreement, although that has not been considered thus far as part of this project t Example of Stewardship Fund Agreement f' . To add context to this discussion, attached is an example of a stewardship fund created as partof a conservation development project in the City of Minnetonka, Minnesota. Although the details would change, the example covers the issues very well and could serve as a model for this project , \ ~: I f,..'.,',."...' l' '1 L f 1 i r I l f .

("Minnstar'), a Minnesota corporation, 7500 West 78th Street, Edina MN 55439, and the City ofMinnetonka ("City''), a Minnesota municipal corporation, 14600 Minnetonka Blvd., Minnetonka MN 55345. The City approved various land use applications submitted by Minnstar for property legally described on attached Exhibit A, ("Clarion Hills"). Minnstar and the City engaged in a cooperative approach toward the development of this property, using conservation development principles. As part of the development proposal approved by the City, Minnstar and the City agreed to establish an endowment fund for supporting on-going stewardship of ecologically ,_..'. sensitive areas in Clarion Hills. Therefore, the parties agree as follows: 1. Fund Created. This Agreement establishes the Clarion Hills Stewardship Fund (the "Fund"), to be financed and administered in accordance with this Agreement. The principal of the Fund will consist of all contributions received pursuant to paragraphs 2 and 3 below and from any other donor. In addition, the principal will be increased annually by anamOlmt equal to ten percent of the investment earnings generated by the Fund in the previous year. The remaining investment earnings will not accrue to the principal and will forever be treated as accumulated investment earnings available for expenditure in accordance with this Agreement. 2. Initial Contributions. The Fund will be initially financed by Minnstar's contribution of $90,000 and the City's contributions of $20,000 in unrestricted funds and $31,050 in park dedication funds. Payment of these amounts into the Fund will completed no later than the date that the City issues the first certificate of occupancy for any construction in Clarion Hills. 3. Annual Contributions. The Fund will also receive funds on an annual basis from the Clarion Hills Homeowner's Association (the "Association"). The Association will annually pay $100 for each residential unit in Clarion Hills that has received a certificate of occupancy , , from the City. The amount of the unit fee will be increased every five years commencing January 1,2006, by the lesser of either (a) 10% or (b) a percentage amount equal to the percentage increase, if any, in the U.S. Department of Labor) Bureau of Labor Statistics Consumer Price Index (All Items, All Consumers, 1982-1984=100) which occurred during the previous five-year period for the Midwest Urban Region Consolidated Metropolitan Statistical Area. The Association will pay the fees by January 31 of each year, accompanied by a report reciting the number of residential units that have been constructed and the units which have paid the fee. The Association will be responsible for collecting the amounts from each of the respective residential units, but the City will have the right to specially assess the outstanding amount and any costs of collection against each unit that has not paid the fee to the Association or to the City. Minnstar agrees on behalf of itself and all future owners of @ '. .. r. : property in Clarion Hills that the City can make these special assessments without notice or a ;, f: hearing. On behalf of itself and all future owners of property in Clarion Hills, Minnstar waives all rights to contest the validity of these special assessments. t" ~ - . , ' t. 4. Custodian of the Fund. The City will be the custodian of the Fund and will create a separate account for the Fund. The City will invest the Fund's money in the same manner as f' ! , other City funds, in accordance with the City's written investment policy. On behalf of itself i and all future owners of property in Clarion Hills, Minnstar waives all claims against the City , resulting from the City's custody and administration of the Fund, except for claims caused t' by the City's gross negligence or intentional misconduct. The City may choose at a later date \ to delegate custody and administration of the Fund to a separate trust agency, subject to r' approval of the Association's Board of Directors, which approval may not be unreasonably , , r withheld. t 5. Purposes of the Fund. The Fund will be used to pay: a. the costs of implementing the Clarion Hills Ecological Stewardship Program (the "Program" attached as Exhibit B), I , b. the costs of buying the property described on attached Exhibit C if in accordance with the provisions of paragraph 6 below, f , c. the reasonable costs of Fund administration by any third party, t d. the reasonable costs of collections, e. the reasonable costs of enforcing the tenns of this Agreement or the Conservation r' ::>:> Easements covering Clarion Hills property, and f. the reasonable costs of restoring property damaged in violation of the Conservation ~,.. Easements. t The party bringing the colleCtion or enforcement action or restoring property will fIrst r attempt to recover the costs from the responsible party. If those costs are not recovered, then the Fund may be 'used to reimburse those costs. The Fund will not be used for any costs associated with the trail, rest station and overlook constructed at the tenninus of the trail, or ~ landscaping, all of which are to be constructed ,and maintained by the City within the trail i l easement area that will be created bya separate and subsequent trail easement agreement between the Minnstar and the City. The City will be solely responsible for maintenance of f' that trail, rest station, overlook, and associated landscaping. ( 6. Expenditure Limitations. Expenditures from the Fund will be made only from accumulated l investment earnings whenever possible. Expenditures may be made from principal, but may not exceed an amount greater than the equivalent of the fund's investment earnings for the prior two consecutive years. If expenditures from principal are made, either they must be [, structured as a loan to repay the principal, or no further expenditures of any kind may be " , made from the Fund until investment earnings have reestablished the principal at an amount ! equal to that existing before the expenditures plus ten percent of the investment earnings that would have been earned per year if the principal had not been reduced. Notwithstanding I 2 @ I \, - '. I . . these limitations, the City may use up to $50,000 of the principal of the Fund to buy the property described on the attached Exhibi~ C, as long as the remaining principal is not less than $140,000. 7. Expenditure Procedures. The City Manager and the Association will cooperate in determining what work should be done to implement the Program.

The survey was completed under contract to Bolton & Menk, Inc;, in order to assist the City of Shakopee "1 in completing an Alternative Urban Areawide Review (AUAR). The Valley Green Corporate Center project entails the development of 332 acres (134 hectares) as a '....1 , business park, containing a' mix of office, warehouse, retail, light industrial, and commercial use. Grading for the. project site requires an Army Corps of Engineers i..j Nationwide (Section 404) permit. Therefore, the survey was conducted in accordance .... with the regulations implementing Section 106 of the National Historic Preservation Act U of 1966, as amended (36 CFR Part 800). In accordance with the Minnesota Field f _.:--,: Archaeology Act, the survey was conducted under Minnesota Archaeological License No. 00-032, issued by the Office of the State Archaeologist. The 332-acre (l34.:.hectare) 0 survey area is located in the SElA of Section 9 and the SW1A of Section 10, T115N, 1.-': L.: R22W, Scott County, Minnesota. r:,) The primary objective of the Phase I archaeological survey was to determine if 'J i., any archaeological sites located within the area of potential effect (APE) of the Valley ,:,,;..1 Green Corporate Center project are potentially eligible for inclusion on the National UJ ' Register of Historic Places (NRHP). The Phase I archaeological survey for this project included: (1) research on previously reported sites and archaeological surveys within one U mile (1.6 kilometers [lan]) of the project area; (2) a review of historic plat maps of the project area to assess the potential for historical archaeological resources; and (3) a field survey, including pedestrian reconnaissance and shovel test excavations, to identify J archaeological resources within the project's construction limits.

FIGURE 1 j , I Valley Green Corporate Center Phase I Archaeological Survey ~ P~3 :.1 r-, 2.0 ENVIRONMENTAL SETTING i 1._ _, n The project area lies in the northeastern portion of Scott County, Minnesota, :J within the Minnesota River valley. It is bounded to the north by Trunk Highway (TH) , 169; to the south by the south section line of Sections 9 and 10, T114N, R22W; to the " : westby County State Aid Highway (CSAH) 83; and to the east by Deans Lake. The ;! current land use has been a mix of cultivated land, wooded areas, open, grassy areas, and marsh surrounding Deans Lake. The geomorphic region for the project is the Minnesota Valley Outwash, consisting of nearly level to rolling terraces or outwash and bottomlands along the river "l (Agricultural Experiment Station 1973:10). The Valley Green Corporate Center project d is situated on outwash and terraces and does not encompass river bottoms. Consequently, the soils within the project are made up of loamy sand overlying sand and gravel. The fl project area contains soils belonging to the Hubbard, EstherviIle, Waukegan, and U Zimmerman series, and marsh land (Harms 1959). Although the portion of the project ,_' area where shovel tests were excavated is mapped as Terril sandy loam, 0-6 percent slope ;J (Harms 1959:22), the soil profiles in the test excavations most closely matched those (,- described for Hubbard fine sand, 0-2 percent slope. The Hubbard fine sand profile !~,::.]..' described by the Soils Conservation Service (Harms 1959) consists of a,pproximatelY 7 1:':;9 inches (18 centimeters [cm)) of very dark brown loamy fine sand over 13 inches (33 em) i0.' of dark brown fine sand, over a subsoil of dark brown fine sand that extends to a depth of ,] approximately 38 inches (97 cm). The dominant vegetation over the project area and vicinity at the start of the 1 historic era consisted of prairie grasses, with forest covering the river bottoms. At the LJ time the present field survey was conducted, grading and site preparation had begun in the lower-lying, northern and western portions of the project, which had been under '.l cuIfivation. However, the southern portion of the project, above the 760-feet (ft.) cant. our : ' line (see Figure 1), was intact. This area was covered in a mixture of grasses and trees, including oak, prickly ash and juniper, with the heaviest forest cover occurring on the Q terrace escarpment north ofCSAH 16. n L.J :.'-j,1 .. t .: tJ'O;: l;.'~ ' ...'.:..

" 3.0 METHODS Li ~] The objective of the Phase I archaeological survey was to determine if there are ~J archaeological resources within the Valley Green Corporate Center project area that are potentially eligible for inclusion on the NRHP. The field survey was conducted by L'.'.-1 Elizabeth J. Abel, Kristen M. Zschomler, and Heidi Ekstrom on April 14 and April 17, J 2000. All work was conducted in accordance with the SHPO Guidelines for Archaeological Projects in Minnesota (1993), the Secretary of the Interior's Standards L' " and Guidelines forArcheology and Historic Preservation (48 Federal Register 44716- "i 44740), and the Advisory Council on Historic Preservation's Treatment of Archaeological Properties: A Handbook (1980). U The area of potential effect (APE) for archaeological resources includes the entire 332-acre (134-hectare) parcel slated for development as the Valley Green Corporate rq Center project. Prior to the field survey, The 106 Group conducted preliminary [j background research at the Minnesota Historical Society and the State Historic .. .' Preservation Office (SHPO). The purpose of the background research was to identify any rJ previously recorded sites within the project area, and to assess what types of sites the L project area might potentially contain. ,Staff reviewed the SHPO records to identify 1:' ',' previously reported sites and surveys within one mile (1.6 Ian) of the project area. In lliJ addition, staff also reviewed historical plat maps of the project area to assess the potential , for historical archaeological resources. U A preliminary visual survey was conducted of the entire project area. Areas considered to have low potential for containing cultural resources included low-lying, 1"'1 poorly drained areas; inundated areas; areas with a greater than 15 percent grade; and t.J extensively disturbed or eroded areas in which Holocene deposits have been significantly disturbed. Areas considered to have a moderate or better potential include elevated, well- L~ dr~ined areas wit~in 150 m (500 ft.) of Deans ~ake. The 7.5-minuteseries Eden Pra~rie, , i Mznn., topographIc quadrangle (U.S. GeologIcal Survey [USGS] 1967, photorevIsed 1993) indicates that Deans Lake may once have occupied a larger area within the project tl than it does at ~re~ent, extending west and northwest (see. Figure 1). we. ll-drained, ~J elevated areas wIthin 150 m (500 ft.) of the former potential extent of the lake were induded in the portions of the project assessed as having moderate to better potential for L','.'.'l containing archaeological resources. , j Much of the project area below (north of) the 760-ft. contour line on the USGS L! topographic qu~drangle wa.s already graded at the t.ime ~he field su~ey began. B~c~use , the graded portIOn of the SIte was generally low-Iymg, It was conSIdered to have llIruted B.:-."j. pot.ential for containing archaeological sites. This portion of the project was subjected to U walkover and visual inspection, but no systematic pedestrian survey was conducted here because of its limited potential and the extensive disturbance. '..1 f~l! ~ f. .j ! i W LI Valley Green Corporate Center Phase I Archaeological Survey 0 Page 5 L: The southern portion of the project area, above the 760-ft. contour line, was intact at the time of the survey. This well-drained area may have bordered Deans Lake during wetter climatic periods when the lake potentially filled a more extensive basin. [1 Consequently, this portion of the project was assessed as having a moderate or better probability of containing archaeological resources. Less than 25 percent of the ground surface was visible in this area, and shovel test excavations were the primary survey [1 method used. Archaeologists conducted a pedestrian reconnaissance of this portion of the project at 2S-meter (m) (82-ft.) intervals to determine whether any cultural features were evident and to determine the optimal locations for shovel test excavations. Shovel test U excavations were conducted at IS-m (SO-ft.) intervals. Tests were circular pits measuring approximately 35 em (14 in.) in diameter, and excavated into the underlying subsoil. Soils excavated from shovel tests were screened through lA-inch hardware cloth to ensure '0 the consistent recovery of cultural materials. rn Fieldwork was documented through the field supervisor's log of daily activities, which recorded the locations, methods, and results of reconnaissance testing. All shovel tests were numbered individually and mapped in relation to existing natural and cultural 'U features. Standard documentation of shovel test excavations included descriptions of soil stratigraphy, texture, inclusions (natural and/or cultural), degree of compactness and Munsell@ color chart hue, value and chroma. ~ ...:~ :,: Copies of project documentation, including correspondence, records research, .',.'. field notes, and maps, are maintained by The 106 Group Ltd. at its offices in St. Paul.

Phase I Archaeological Survey [1 Page 6 4.0 BACKGROUND RESEARCH U ~J Prior to the field investigation, The 106 Group staff conducted a review of the L SHPO site files for known archaeological sites and previously surveyed areas within one mile (1.6 km) of the Valley Green Corporate Center project area. Research indicated that LI there are no recorded sites within the project area. There are, however, recorded sites within a one-mile (1.6-km) radius of the project area. i I Since the rnid-1970s, a number of archaeological investigations have been I conducted in the general vicinity of the project area in Scott County, largely in response L' ,', to federal- and state-mandated cultural resource inventory, evaluation, and mitigation J requirements. These have resulted in the identification of several American Indian ;. : habitation and mound sites, artifacts and lithic scatters, and cultural material findspots, as well as post-contact, Euro-American sites in Scott County. Few of the recorded g archaeological sites in the region and in the county have been either intensively tested or ~ ,,": investigated through extensive excavation and analysis, and many have not been J identified or dated beyond the level of the major cultural tradition. Site 21SC25 is located in the NY2,of the SE'A of Section 2, T1l5N, R22W. The :.1 site is an earthwork that is possibly a burial mound, although the site has not been authenticated. Several other habitation and mound group sites. have been identified in the ilij. general vicinity of the project, but they are located two or more miles from the Valley J Green Corporate Center project area. Known sites in the vicinity tend to be located on the bluff edge overlooking the Minnesota River floodplain as well as adjacent to the riverine and lacustrine features within the Minnesota River bottomlands or floodplains. J A number of surveys have been conducted with negative results within one mile (1.6 km) of the project area. Woolworth (1976) surveyed the WY2 of Section 15 and the J EY2 of Section 16, Tl15N, R22W, and did not identify any sites. Mather (1995) conducted a reconnaissance survey covering the NY2 of the NE'A of Section 10, T115N, R22W, reporting no sites in the area. The Bureau of Indian Affairs (Berg 1995) surveyed ~..~ an area roughly covering the SW'A and SY2 of the NWl,4 of Section 15; the SE'A and the " d SY2 of the NE'A and the NE-NEIA of Section 16; and NY2 of the NE'A and the NE-NW'A ';".1 of Section 21. That survey was also negative. The 106 Group Ltd. (Peterson and 'I Schmidt 1997) conducted a Phase I survey immediately east of the current project arejl for 1 i.....I the proposed Southbridge Development. This survey of 550 acres (223 hectares) within the BE'A of Section 10, the SW'A and the WY2 of the SE'A of Section 11, the NY2 of the I NEl,4 of Section 15, and the NY2 of the NW'A and the NW-NE'A of Section 14 was J negative. ;j Background research also included a review of historic plat maps of the project :..." , ., t, area to assess the.. potential for historical archaeological sites. Maps from 1858, 1890, ] 1898, 1913, and 1944 wereexarnined during the review. The 1890 plat (c. M. Foote & ~,:-.. 'J ' ' LJ ,Valley Green Corporate Center Phase I Archaeological Survey (1 Page 7 L,j Co.) is the first map to show a structure within the project area. The 80 acres forming the south half of the SEtA of Section 9 belonged to a John Kline, and this was presumably,his house. The house is shown on plat maps from 1898 (Northwest Publishing Company), [J 1913 (Webb Publishing Company), and 1944' (Dahlgren), with the same 80-acre parcel , belonging to a Christ Anderson throughout these decades. The property does not predate 1870 and is not associated with any historically significant events or persons.

The field methods included a walkover and visual inspection of the entire project area to assess the condition of the r[ portions of the project that had a moderate or better potential for containing significant L archaeological resources. , i Grading and preparation of the site for development had begun prior to the field 61 survey. Site preparation included demolition of the residence that stood in the southeast portion of the project area, and grading of the surrounding land, as well as grading/filling D and drainage pond construction north of the approximately 760-f1. contour on the USGS ILl topographic map. However, the project area at the base of the escarpment running along the southern edge of the project area above the 760-ft. contour was intact. From a review D of the USGS top.ographic qua~ran~le, th~s area may have formed t?e south~rn shore of lW Deans Lake dunng wetter clImatIc penods when the lake and Its assocIated marsh ;':.;.1' expanded. A. s a conseq~ence, this ~or:tion of the pr~ject area w.as assessed as having a L moderate or better potentIal for contammg archaeologIcal resources. " Archaeologists conducted a pedestrian survey of the higher potential area in the ~~ southern portion of the project (above the 760-ft. contour) at 25-m (82-ft.) intervals to . ,\ determine the optimal locations for shovel test excavations and to identify any surface U evidence of archaeological features or materials. The area is covered largely in grasses I:,. with scattered trees and brush, with denser tree cover immediately adjacent to the foot of the escarpment. Although modern appliances and trash were strewn throughout the { \ wooded escarpment.and along its base in some locations, the survey identified no surface U evidence of archaeological features or artifacts. A total of 14 shovel tests were excavated within the southern portion of the w project area as indicated in Figure 2. Tests extended into the underlying sand subsoil, and reached maximum depths of between 57 and 90 em below the surface. A typical soil 1.111 profile exposed during testing included a surface horizon of very dark gray (lOYR 311) U fine loamy sand over a thick horizon of dark grayish-brown (10YR 3/2) fine sand, overlying a brown (10YR 4/3) fine sand subsoil.

The project area includes approximately 332 acres (134 hectares) within the SElAof Section 9 [I and the SWIA of Section 10, Tl15N, R22W, Scott County. The survey was conducted under contract with Bolton & Menk, Inc., in order to assist the City of Shakopee in completion of an AUAR, and in compliance with Section 106 of the National Historic l' Preservation Act, as amended (36 CFR Part 800). .. : ., The survey included background research to identify previously recorded sites and l\ previous archaeological investigations within the project area and within a one-mile (1.6 ) :l l':.~ kilometer) radius of the project. The project area contains no recorded sites and no [) portion of the present project has been previously surveyed. In addition, background research included a review of historic plat maps to assess the project area's historical ;:.,'" archaeological potential. While a residence occupied the southwest portion of the project "-'. [1 area from the late 1800s until its recent demolition, the property lacks association with historically significant persons or events. .1 biJ The field survey included a walkover and visual inspection of the entire project area to assess which portions possessed a moderate or better potential for containing intact archaeological resources. A slightly elevated portion of the site along the base of lJ the escarpment bordering the project's southern margin was identified as the only area of the project with moderate or better . archaeological sites potential. This area was intensively surveyed through pedestrian reconnaissance and shovel test excavations. The [1 field survey identified no archaeological resources. The Phase I survey identified no archaeological sites within the Valley Green L, Corporate Center project area, and indicates that there is little probability that the project area contains unidentified archaeological resources of historical significance. The 106 Group therefore recommends that the project warrants no further archaeological b1 investigation. .....'1 ,',:; II . , LJ , ~ci t: ,'- ,; J [t .. .J L!

BMI Project No. T11.20132 T115 R22 S9 & S10, Shakopee, Scott County . , SHPO Number: 2000-1523 U Dear Mr. Knapper: n Thank you for the opportunity to review and comment on the above project. It has been reviewed pursuant to the responsibilities given the Minnesota Historical Society by the Minnesota Historic bJ Sites Act and the Minnesota Field Archaeology Act. ", [l We believe that there is a good probability that unreported archaeological properties may be present in the project area. , Therefore, we recommend that a survey of the area be completed. The survey ~J musUneet the requir.ements of the Secretary of the Interior's Standards for Identification and Evaluation, and should include an evalua'tion of National Register eligibility for any properties which ','.,', are identified. For your information, we have enclosed a list of consultants who have expressed an interest in undertaking such surveys. [J If the project area can be documented as previously disturbed or previously surveyed, we will re- evaluate the need for survey. Previously disturbed areas are those where the naturally occurring U post-glacial soils and sediments have been recently removed. Any previpus survey work m!Jst'meet contemporary standards. I Please note that this comment letter does not address the requirements of Section 106 of the ' I National Historic Preservation Act of 1966 and 36CFR800. procedures of the Advisory Council on ' I l..' Historic Preservation for the protection of historic properties.

I Appendix G - Mitigation Plan (The attached plan is the plan that was submitted as part of the 2002 AUAR. It will be revised based on comments received from the review of the 2003 AUAR, if necessary.) MITIGATION PLAN INTRODUCTION The Mitigation Plan, as submitted is comprehensive and is intended to address issues contained in the FAUAR dated July, 2000 and the Supplement dated July, 2002. This Mitigation Plan is submitted as a part of the Alternate Urban Area-wide Review (AUAR) process to provide reviewers, regulators, and prospective tenants with an understanding of the actions necessary to protect the environment and limit impacts by the proposed project Many of the potential environmental impacts within the project boundary are associated with the specific improvements, activities and operations of tenants who will choose to locate within Valley Green Business Park. Therefore, those impacts cannot be precisely defined until the appropriate proposals are made. The primary vehicles for mitigation are the effective use of existing codes, rules, and regulations together with the enforcement options which pertain thereto. These enforcement options include: . Execution of a Comprehensive Development Agreement which may include Planned Unit Development (PUD) Requirements . Enforcement of the Permitting Requirements of All Agencies . Require Submission of Performance Bonds . Initiation of Civil Suits & Restraining Orders This recommended mitigation plan is divided into three levels: 1. Goals - This level defines broad concepts to be achieved. a. ,Strategies - This level identifies basic philosophies which could help achieve the related goal. 1. Actions - This level precisely lists key activities which may be employed to achieve the associated goal.
