Existing and future development along the corridor has raised concerns regarding the future of CSAH 16. Although no current plans to reconstruct CSAH 16 are included in the County's 5 -Year Capital Improvement Program, the County determined the need to study and better define the future design and right -of -way needs along the corridor. The City of Shakopee previously identified improvements to the CSAH 83 at the CSAH 16 intersection as part of their transportation plan. These improvements included a realignment of CSAH 16 to line up with the future extension of 17th Avenue to the west. Recent development proposals in the northeast quadrant of the CSAH 83 at CSAH 16 intersection have initiated implementation of those improvements. That project is planned for construction during the spring and summer of 2002. A related issue that was identified as part of that project was the future alignment of CSAH 16 adjacent to the Dean Lake neighborhood east of CSAH 83 and the planned development. Should the existing roadway alignment be maintained and widened to accommodate future traffic growth, the existing homes adjacent to CSAH 16 would be located extremely close to the roadway or the houses taken completely. Based on this issue, the City requested that the County study the CSAH 16 alignment through the Dean Lake neighborhood to McKenna Road. There has also been an ongoing concern with the grade on CSAH 16 approaching TH 13. In addition, issues have been raised by the city of future — access along the corridor, specifically to the north of CSAH 16. Future development potential north of CSAH 16 and past requests by the City of CSAH 16 Corridor Planning Study Page 1 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 Savage to include improvements to CSAH 16 in the County's capital improvement program, was the basis for including this section of CSAH 16 in the study. Based on these issues and concerns, County Staff brought a request to the County Board, who then initiated a study of the CSAH 16 corridor between CSAH 83 and TH 13. WSB & Associates, Inc. was retained by the County to prepare this planning level study. The scope of the study is to provide a planning level analysis of the CSAH 16 corridor. A planning level study evaluates and/or analyzes enough data to provide a thorough understanding of the corridor and its issues. The study is not intended to be the final design or final cost estimate of any potential improvements in the corridor. The analysis of potential improvements is based on many assumptions. More detailed analysis of the design geometrics and environmental issues will be required if a project is selected and when funding becomes available. The study is divided into two phases: • Phase I — CSAH 83 to CSAH 18 • Phase II — CSAH 18 to TH 13 Each phase of CSAH 16 will be evaluated with respect to traffic operations, environmental impacts, design considerations, right of way and costs. Figure I in Appendix A shows a study location map. The following sections of this report outline the goals and objectives of the study, the public participation process that was undertaken as part of the study, an analysis of the identified potential alignment options for the corridor, implementation plan, and findings and recommendations of the study. CSAH 16 Corridor Planning Study Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 Page 2 Study Goals and Objectives The primary goal of the CSAH 16 study is for it to serve as a guide to Scott County and the Cities of Shakopee and Savage as development occurs, by better defining the future designs and right -of -way needs for the CSAH 16 corridor between CSAH 83 and TH 13. The primary elements of this goal were identified as: safety, system efficiency, and environmental impacts. Each is discussed below: Safety. It is essential that the planned roadway be as safe as possible with respect to traffic operations and design characteristics. CSAH 16 should have adequate capacity for existing and future traffic needs and should meet state and local design standards. System Efficiency. CSAH 16 has a current functional classification as a B minor arterial of the metropolitan area system plan. Roadway functional classification is defined as "a roadway or street network, which collects and distributes traffic from neighborhood streets to collector roadways to arterials and ultimately to the metropolitan highway system ". Roads are placed into categories based on the degree to which they provide access to adjacent land or provide mobility for through traffic. Ideally, roads are designed to perform a designated function and are located to best serve the type of travel needed. A minor arterial roadway such as CSAH 16, connects important locations within the County with access to the metropolitan highway system and other locations within the region. Minor arterial roadways serve as boundaries to neighborhoods and distribute traffic from collector streets. CSAH 16 Corridor Planning Study Page 3 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 It is essential for system efficiency that a series of east -west and north- south arterial roadways be developed to move traffic through the County. Currently, between TH 169 /TH 13 and CSAH 42, no continuous east -west roadway exists. As development continues to occur in these areas and as traffic on TH 169 /TH 13 and CSAH 42 continues to increase, a need for this continuous east -west route will become more essential to serve the travel needs of the County. Environmental Impacts: To the extent possible, environmentally sensitive areas along the proposed corridor should be avoided or be minimally impacted by any proposed alignment option. That is, any wetland, floodplain, wooded area, bluff line, etc, should be evaluated to determine the extent of impact for each identified options. It should be noted that any improvement project that is identified and is proposed to be brought through the design process will be required to meet all state and/or federal environmental regulations including preparation of environmental documents such as Environmental Assessments and/or Environmental Assessment Worksheets, etc. as required. In order to meet the above goals, the following study objectives were developed: 1. Identify the existing CSAH 16 deficiencies. 2. Identify and evaluate alternative CSAH 16 concepts for safety, system efficiency, and environmental impacts. 3. Recommend proposed concepts as necessary to accommodate existing and future transportation needs. 4. Prepare an implementation plan for identified concept. CSAH 16 Corridor Planning Study Page 4 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 A public participation process was undertaken for the CSAH 16 study to solicit input from potentially effected interests along the corridor. This process has included the following: A. Public Information Open Houses Two public information open houses were held during the course of the study to solicit input from the public on their issues relating to the corridor. Open House No. 1 (Phase I Study) — October 9, 2001: The first public information open house for the Phase I portion of the study between CSAH 83 and CSAH 18 was held on Tuesday, October 9, 2001 at the Park Inn and Suites Hotel from 4:00 p.m. to 7:00 p.m. Approximately 57 persons were in attendance at the meeting to provide input to the County and City. The purpose of this open house was to give all interested groups along the corridor an opportunity to raise issues and concerns for CSAH 16. Open House No. 1 (Phase 11 Study) — October 11, 2001: The first public informational open house for Phase II of the study between CSAH 18 and TH 13 was held on Thursday, October 11, 2001, at the Savage City Hall, from 4:00 p.m. to 7:00 p.m. Approximately 9 persons were in attendance at that meeting to provide input to the County and City. The purpose of this open house was also to give the interested groups along the corridor an opportunity to raise issues and concerns. CSAH 16 Corridor Planning Study Page 5 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 Open House No. 2 — February 11, 2002: The second public information open house for the combined Phase I and Phase H studies was held on Monday, February 11, 2002, at the Park Inn & Suites Hotel, from 4:00 p.m. to 8:00 p.m. Approximately 112 persons were in attendance to provide comments to the Cities and County. The purpose of the open house was to present the proposed alignment concepts for CSAH 16 and receive comments on each realignment option from the potentially affected interests. For each open house, comments were received by comment cards, mailed letters, and emailed letters. Copies of the public information meeting notices, handouts and comment cards are included in Appendix B. Discussion of public opinion on each realignment option is included in the alternative evaluation, Section VI. B. Agency Input Agency meetings have been held with the City of Shakopee, City of Savage, the Minnesota Department of Natural Resources (MDNR), Scott County Natural Resource Department, and the Lower Minnesota River Watershed District. These meetings were held to familiarize them with the study and to solicit input from the agencies on their issues relating to the corridor and the proposed realignment options. C. Web Page Scott County has developed a page on the County's web site that provides the public the opportunity to view the most up to date information with respect to the CSAH 16 study. The County web site is www.co.scott.mn.us The page in the web site is under "News and - Events ", "Transportation Studies ". CSAH 16 Corridor Planning Study Page 6 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 ♦ �1 11 11 •` 'I 1'I Several transportation alignment issues were identified to be addressed as part of the CSAH 16 corridor planning study. Three specific areas were identified and are discussed below: A. Dean Lake Area As discussed previously, the City of Shakopee has identified improvements to the CSAH 83 at CSAH 16 intersection as part of their transportation plan. These improvements include a realignment of CSAH 16 to line up with the future extension of 17 Avenue to the west. With recent development proposals in the northeast quadrant of the CSAH 83 at CSAH 16 intersection, these improvements have been initiated. As part of the CSAH 83 /CSAH 16 realignment planning process, the future alignment of CSAH 16 in front of the Dean Lake neighborhood east of CSAH 83 was raised as an issue. The CSAH 83 /CSAH 16 realignment feasibility report included an extensive traffic analysis of the CSAH 83 and CSAH 16 corridors. The results of that study concluded that the realignment of CSAH 16 to line up with the future 17th Avenue was feasible and was approved by both the City of Shakopee and Scott County. Future improvements to CSAH 16 between CSAH 83 and McKenna Road would impact the residents adjacent to Dean Lake. Several future improvement options were identified, including: Widening the existing roadway evenly to both sides of the existing CSAH 16; shifting the alignment south and maintaining the existing CSAH 16 as a frontage road; and shifting the entire alignment north, maintaining the south right -of -way - line. Each of these options are discussed and evaluated as part of this study. CSAH 16 Corridor Planning Study Page 7 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 A related issue with the Dean Lake area is the potential acquisition of Mdewakanton Sioux Community land south of existing CSAH 16. Each of the potential alignment options will require acquisition of right -of -way from the Mdewakanton Sioux Community. It is the intent of this study to recommend the optimal alignment option with respect to cost and benefit analysis and impacts to the adjacent properties. The County will continue to work with the Mdewakanton Sioux Community on potential future right -of -way acquisitions. Currently, CSAH 16 has two intersections at CSAH 18, creating a jog in the county road alignment. As part of this planning level study, potential realignment options to eliminate the jog in the county road system are evaluated. By eliminating this jog, CSAH 16 could provide a continuous east -west arterial route, and could provide a safer roadway by eliminating or restricting intersections. Several realignment options were identified using both the north (Eagle Creek Boulevard) intersection and the south (134 Avenue) intersection. Each of these realignment options is discussed as part of the planning level study. C. TH 13 Area As discussed previously, the current grade approaching TH 13 is an ongoing concern of the County and City of Savage. Currently, this grade is in excess of 8.5 %. Typically, grades of 5% or less are desirable on roadways such as CSAH 16. The study will identify potential alignment options that will help reduce _ the grade to the extent possible. CSAH 16 Corridor Planning Study Page 8 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 V. Ph 8, A. Geometric Layout /Concept Development CSAH 16, from CSAH 83 to CSAH 18, is currently a two -lane roadway with ditches for drainage and minimal shoulders. West of CSAH 83, CSAH 16 is a four -lane undivided roadway, which currently terminates at CSAH 17 in the City of Shakopee. The City of Shakopee, in their transportation plan, identified the realignment of CSAH 16 to line up with the extension of 17th Avenue. 17th Avenue would extend from CSAH 83 to CSAH 15. The segments of 17 Avenue that have been constructed are four -lane facilities with turn lanes at major intersections. The intersection of CSAH 83 at CSAH 16 is currently planned for reconstruction in the spring/summer of 2002. This will include the realignment of CSAH 16 to line up with the future extension of 17th Avenue. This roadway will be constructed to a four -lane divided facility with turn lanes at major intersections. Existing (2000) average daily traffic (ADT) volumes on CSAH 16 between CSAH 83 and CSAH 18 range from 2,350 — 3,250 vehicles per day. Based on the County's transportation plan, this traffic is expected to increase to 12,500 - 15,000 vehicles per day by 2020. Table I below illustrates the typical capacities for specific roadway designs, as identified in the County's Transportation Plan. CSAH 16 Corridor Planning Study Page 9 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 Table I Roadway Design vs Design Volume Highway Design (Cross - Section) Design Volume 2 -Lane Less than 7,500 3 -Lane 7,500 to 15,000 4 -Lane Divided 15,000 to 30,000 6 -Lane Divided More than 30,000 Source: Scott County Transportation Plan Based on the County's traffic projections of up to 15,000 vehicles per day in the year 2020 for the CSAH 16 corridor, a four -lane divided facility will be required for the section of road between CSAH 83 and CSAH 18. The roadway typical section was developed based on a rural (no curb and gutter) cross section. This means that the drainage from the roadway will be accommodated through ditches adjacent to the roadway. This type of section will require slightly more right -of -way, however, it has a reduced cost as a result of not requiring a storm sewer system. In the areas where right -of -way becomes an issue, outside curb and gutter could be considered. The area adjacent to the Dean Lake neighborhood was assumed as an urban (with curb and gutter) cross - section. Figure 2 in Appendix ,4 illustrates the proposed Phase I Typical Sections. Access along the corridor will meet the County's access spacing guidelines and be provided at the following locations: ® McKenna Road ® Future CSAH 21 ® Pike Lake Trail ® Foothill Trail CSAH 16 Corridor Planning Study Page 10 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 • Hilldale Drive • Muhlenhardt Road Figures 3.1, 3.2, and 3.3 in Appendix A illustrate the proposed baseline concept of a four -lane divided facility with turn lanes at the proposed access points on existing CSAH 16 alignment. B. Right -of -Way Determination The County Transportation Plan identifies typical right -of -way widths for specific roadway designs. To accommodate a cross - section of this width, a 150 -foot right -of -way corridor is required for the rural section and a 130 - foot right -of -way is required for the urban section. Table 2 below illustrates the typical right -of -way widths based on roadway cross - section. Tahle 2 Roadway Right -of -Way Width Highway Design (Cross- Section) Right -of -Way (Feet) 2 -Lane 80-150 3 -Lane 100 —150 4 -Lane Divided 120 —200 6 -Lane Divided 150 —200 Source: Scott County Transportation Plan C. Environmental Review An environmental review of the corridor was conducted. This included documenting existing environmental concerns, including: • Wetlands • Wooded areas • Bluffs CSAH 16 Corridor Planning Study Page 11 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 ® F000dplains ■ Drainage patterns ® Other environmental issues The environmental issues that have been identified adjacent to CSAH 16 between CSAH 83 and CSAH 18 include: rMISM 7 RM Though not directly impacted, careful consideration has been given to directing all drainage from potential roadway improvements through ponding areas for treatment prior to outletting into Dean Lake as part of this study. During detail design of any identified alignment, an analysis will be completed to accommodate this drainage. Wetland /Floodplain Areas: The wetland and floodplain areas along the corridor were identified and specific consideration will be given to these areas with each design option. No identified floodplains were found in the study area. However, several wetlands exist, specifically north of the existing CSAH 16 alignment. Any realignment option that impacts a wetland will be required to follow all state and federal wetland regulations. Prior Lake Channel: This channel is a DNR- protected stream and will require coordination with the DNR and Prior Lake /Spring Lake Watershed District during any design activities. The current channel flows under the existing CSAH 16 and will flow under any proposed option. A permit will be -- required for any improvement which impacts the stream. This permit will be submitted to all impacted agencies, including NIDNR, Board of CSAH 16 Corridor Planning Study Page 12 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 Water & Soil Conservation, and Prior Lake /Spring Lake Watershed District. Wooded Areas: Wooded areas in the study corridor were identified and delineated based on aerial mapping. Although these areas are not specifically identified by DNR as sensitive areas, attention will be given to these areas during the option development. Bluff Areas: Currently, two bluff areas exist through the study area. The first bluff area is north of existing CSAH 16, paralleling the roadway from CSAH 83 to CSAH 18. A second bluff area exists south of CSAH 16 between Pike Lake Trail and CSAH 18. These bluff areas are not DNR protected, however, consideration will be given to them during concept development. It should be noted that the County's Comprehensive Plan, which serves as a guide for future growth and development in the unincorporated areas of the County, includes natural resource goals for dealing with development in bluff areas. These goals (I -3 and 1 -5) weren't developed specifically for determining roadway alignments, but do indicate environmental responsibility, and are provided in Appendix D for reference. Figures 4.1, 4.2, and 4.3 in Appendix A show the environmentally sensitive areas along the Phase I corridor. Appendix C includes agency review letters received to date for the corridor. D. Future Ponding Future ponding for roadway drainage was identified based on the proposed roadway cross - section. All drainage west of McKenna Road is CSAH 16 Corridor Planning Study Page 13 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 accommodated in the storm sewer design of the proposed improvements at CSAH 83 and CSAH 16 currently under construction. Drainage from this area will use storm sewer to get to the CSAH 83/16 system. From McKenna Road east to the future CSAH 21, all drainage will be accommodated through ditches on both sides of the roadway, ending up in a proposed 1.2 -acre pond located in the northwest quadrant of future CSAH 21 at CSAH 16. Also, drainage from Pike Lake Trail west to future CSAH 21 would be accommodated through ditches and ultimately into the proposed 1.2 -acre pond. From Pike Lake Trail to the Prior Lake Channel, drainage would be accommodated through ditches to a 0.3 -acre pond just west of the channel. From CSAH 18 to Pike Lake Channel; the drainage south of CSAH 16 will be handled by ditch flow to a 0.7 -acre pond located just east of Foothill Trail. North of CSAH 16, runoff will sheet -flow to the north or could be accommodated with a curb and gutter storm sewer system to the 0.7 -acre pond east of Foothill Trail. Figures 4.1,4.2, and 4.3 show the existing drainage patterns and potential ponding locations. E. Preliminary Cost Estimate A preliminary cost estimate for the baseline alternative of widening the existing two -lane roadway between CSAH 83 and CSAH 18 on the existing alignment to a four -lane roadway with turn lanes at intersections is estimated at $11,100,000, based on 2002 dollars. This estimate includes construction cost for grading, pavement, drainage, and other appurtenant work. A 15% contingency was assumed for other items not included in the estimate. The cost also includes potential right -of -way (ROW) costs. The ROW costs are based on current (2002) Scott County appraised values with a 1.5 factor. The cost breakdown by segment is shown in Table 3 below: CSAH 16 Corridor Planning Study Page 14 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 Table 3 Phase I— Preliminary Baseline Cost F. Alignment Options Alignment options were identified for three Phase I areas between CSAH 83 and CSAH 18. Each is discussed below. Evaluation of the alignment options is included in Section VII of this report. 1. Dean Lake Area ® Existing Alignment Existing alignment, widening roadway equally on both sides. The base line cost is based on this option. (Figure 3.1) ® Option A1 : Shift the alignment of CSAH 16 south, maintaining the existing CSAH 16 as a frontage road, providing access to the frontage road via an intersection east of CSAH 83 and at McKenna Road. (Figure S) ® Option A2 : Shift the alignment of CSAH 16 north, maintaining the existing south right -of -way line.

Geometric Layout /Concept Development CSAH 16, from CSAH 18 to TH 13, is currently a two -lane roadway with paved shoulders and ditches for drainage. East of TH 13, CSAH 16 was recently reconstructed to a four -lane divided roadway with turn lanes. CSAH 16, east of TH 13, currently terminates at the Scott / Dakota County border where the roadway extends to Dakota CSAH 5 as Williams Drive, a Burnsville city street. Existing (2000) average daily traffic (ADT) volumes on CSAH 16 between CSAH 18 and TH 13 range from 4,050 — 4,300 vehicles per day. Based on the County's transportation plan, this traffic is expected to increase to 9500 vehicles per day by 2020. Table 1 in Section V -A illustrates the typical capacities for specific roadway designs, as identified in the County's Transportation Plan. Based on the County's traffic projections of up to 9,500 vehicles per day in the year 2020 for the CSAH 16 corridor, a three -lane facility could be sufficient for the section of road between CSAH 18 and TH 13. However, a four -lane divided section should be considered for the following reasons: The 2020 forecasts were developed based on 20 -year development anticipated in 1998. Even in the past three years, changes in zoning are expected to result in an increase in traffic on CSAH 16 for 2020. 2. This segment is not currently on the County's 5 -Year Capital Improvement Program for construction. The design volume will therefore be based on expected traffic later than 2020. CSAH 16 Corridor Planning Study Page 17 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 3. The City of Savage has requested reconstruction of this segment of CSAH 16 to a four -lane section. The roadway typical section was developed based on an urban (with curb & gutter) cross - section. This means that the drainage from the roadway will be accommodated through a storm sewer system. This type of section will require slightly less right -of -way, however, it has an increased cost as a result of the storm sewer system. Figure 10 in Appendix ,4 illustrates the proposed Phase II typical section. Access along the corridor will meet the County's access spacing guidelines and be provided at the following locations: • Kelly Circle • Hillsboro Avenue • Boone Avenue • Foxberry Road Figure 11 illustrates the proposed baseline concept of a four -lane divided facility with turn lanes at the proposed access points on existing alignment. B. Right -of -Way Determination Based'on the roadway cross - section, the County has identified typical right -of -way widths for specific designs. The proposed design for the CSAH 16 corridor is a four -lane divided urban section facility with curb and gutter. To accommodate the cross - section of this width, a 130 -foot right -of -way corridor was assumed. Table 2, in Section V — B, illustrates the typical right -of -way widths based on roadway cross - section, as identified in the County's Transportation Plan. _. CSAH 16 Corridor Planning Study Page 18 - Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 C. Environmental Review An environmental review of the corridor was conducted. This included documenting existing environmental concerns, including: • Wetlands • Wooded areas • Bluffs • Floodplains • Drainage patterns • Other environmental issues The environmental issues that have been identified adjacent to CSAH 16 between CSAH 18 and TH 13 include: Eagle Creek: Eagle Creek is located north of CSAH 16. It is a DNR protected trout stream. An Eagle Creek aquatic management area has been established. Any improvements in this area will require DNR review and approval. No drainage from the roadway will be allowed to flow into Eagle Creek. Wetland /Floodplain Areas: The wetland/floodplain areas along the corridor were identified and specific consideration will be given to these areas with each design option. No floodplains are identified in the study corridor area. However, several wetlands have been identified and located north of existing CSAH 16. Any potential roadway realignment will follow all state and federal wetland regulations. CSAH 16 Corridor Planning Study Page 19 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 Wooded Areas: Wooded areas in the study corridor were identified and delineated based on aerial mapping. These areas are identified by DNR as areas of modest biodiversity significance. The DNR has provided initial comments on the proposed study including a map showing sensitive areas. This is included in Appendix C. Consideration will be given to these areas during the option development. Savage's tree preservation ordinance will be followed with any detail design. Boiling Springs: The boiling springs area is located just north of CSAH 16. Although it appears that no options will impact this area directly, a more detailed study of the groundwater seepage, runoff from this area will be required for any realignment option considered. See Appendix C for DNR initial comments. Bluff Areas: The most significant bluff area occurs north of CSAH 16, paralleling the roadway from CSAH 18 to TH 13. Even though the bluff is not DNR protected, consideration will be given to impacts to it during option development. The County bluff policies will be followed with any detail design option selected. Figure 12 in Appendix A shows the environmentally sensitive area along the Phase II corridor. Appendix C includes agency review letters received to date. CSAH 16 Corridor Planning Study Page 20 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 D. Future Ponding Future ponding for roadway drainage was identified based on the proposed roadway cross - section. It is assumed that all roadway drainage will be accommodated in a curb and gutter storm sewer system. West of Hillsboro Avenue, runoff will be directed to CSAH 18 and into the existing storm sewer system. Boone Avenue west will flow to a 0.5 acre pond located south of CSAH 16. Boone Avenue east to TH 13 will flow to a proposed 0.8 acre pond in the north west quadrant of CSAH 16 and TH 13. Figure 12 Shows the proposed drainage patterns and pond locations. E. Preliminary Cost Estimate A preliminary cost estimate for the baseline alternative of widening the existing two -lane roadway between CSAH 18 and TH 13 on the existing alignment to a four -lane roadway with turn lanes at all intersections is estimated at $3,700,000, based on 2002 dollars. This estimate includes construction cost for grading, pavement, drainage, and other appurtenant work. A 15% contingency was assumed for other items not included in the estimate. The cost also includes potential right -of -way (ROW) costs. The ROW costs are based on current (2002) Scott County appraised values with a 1.5 factor. The cost breakdown is shown in Table 4 below: CSAH 16 Corridor Planning Study Page 21 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 Table 4 Phase H— Preliminary Baseline Cost Construction Cost R. 0.

Alignment Options Alignment options were identified for two areas between CSAH 18 and TH 13. Each is discussed below. 1. CSAH 18 Intersection Area Existing Aligmnment Existing CSAH 16 alignment widening roadway equally on both sides. (Figure 11) Option B : Realign CSAH 16 north from Boone Avenue to the north CSAH 16 intersection (Eagle Creek Blvd). (Figure 13) 2. TH 13 Approach ExistinzAIignment Existing CSAH 16 alignment widening roadway equally on both sides. (Figure 11) Option CI : Shift CSAH 16 alignment slightly north to improve the grade on CSAH 16 approach. (Figure 14) ■ Option C2 : Realign CSAH 16 north from TH 13, north of the cemetery, to west of Boone Avenue to improve the grade on CSAH 16 approach. (Figure 15) CSAH 16 Corridor Planning Study Page 22 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 • 1 "1 11 1 1 1 I' Several alignment issues were identified for each of the issue areas discussed in Section IV. Each alignment option was evaluated based on five criteria. Each criteria is discussed below: 1. Traffic Traffic operation of each option will be evaluated and reported in: ® Level of Service — Graded A to F ® Vehicle Delay — In seconds per vehicle ® Operating Speed — In miles per hour Each realignment scenario was analyzed for the AM and PM peak hours for both existing (2002) and future (2020) traffic conditions. The existing (2002) traffic volumes are based on turning movement counts conducted by Scott County in March 2002 at both CSAH 16 intersections on CSAH 18. The CSAH 18 at Preserve Trail intersection volumes were developed based on estimated traffic generated from the existing area. The 2020 volumes were developed, as a worst case, assuming the County's 20 -year state aid growth factor of 1.9 for traffic on CSAH 16. It was estimated, based on the County's Transportation Plan, that the projected 2020 volumes on CSAH 18 would be similar to existing volumes, assuming the CSAH 21 improvements were completed. A traffic signal warrant analysis was conducted for the three intersections within the study area. The intersection includes CSAH 18 at Preserve Trail, CSAH 18 at CSAH 16 north intersection — (Eagle Creek Boulevard), and CSAH 18 at CSAH 16 south intersection (134 Avenue). The 2020 warrant analysis concluded that CSAH 16 Corridor Planning Study Page 23 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 a traffic signal system would only be warranted at the intersection of CSAH 16 north intersection (Eagle Creek Boulevard). The other two intersections would not justify a signal system based on the current assumptions and projected traffic volumes. The existing capacity and level of service analysis was prepared as a base line to compare future traffic analysis of each realignment option. The results of the existing capacity level of service analysis are illustrated in Table S. Table S - Traffic Analysis No Build —Existing Geometrics The traffic analysis assumes that for the existing (2002) conditions, stop signs are located at all three intersections and for the future (2020) conditions, a traffic signal is located at the CSAH 16 north intersection. Based on this analysis, the overall CSAH 18 system would be operating at a level of service A with vehicle operating speeds on CSAH 18 between Preserve Trail and the south CSAH 16 intersection, of 50 MPH with the existing (2002) volumes. The future (2020) system level of service would be at a LOS B with CSAH 18 operating speed of 32 MPH.

The future (2020) system level of service would be at a LOS B with CSAH 18 operating speed of 32 MPH. CSAH 16 Corridor Planning Study Page 24 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 2. Environmental Review Each concept was evaluated with respect to impact on environmentally sensitive areas. They will be labeled as high, medium, or low impacts, with high being the most impacted and low being the least impacted. The areas of evaluation include: • Wetland/Floodplain Impacts • Wooded Area Impacts • Bluff Area Impacts • Boiling Springs Impacts • Eagle Creek Impacts • Prior Lake Channel • Dean Lake Impacts 3. Design Considerations Three areas were considered when reviewing each alternative with respect to design. ■ Design Speed A design speed of 45 MPH to 55 MPH is desirable for the corridor. ■ Vertical Alignment (Grade) A grade of less than 5% on the roadway is desirable, 5% to 8% is acceptable, and over 8% is undesirable. ■ Continuity East -west continuity of the roadway (i.e., no jogs in county road) is desirable for safety and efficiency of the County roadway system. CSAH 16 Corridor Planning Study Page 25 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 4. Right -of -Way Impacts As discussed previously, a 150 -foot right -of -way corridor would be required to accommodate the proposed roadway rural cross - section and 130 -foot right -of -way corridor to the urban cross - section. It was assumed that if a residential structure was within 50 feet of the edge of roadway, the parcel would be a total take. The right -of -way impacts for each option are identified as: ® 4rea The number of acres of required for each option. ® Total takes The number of total takes for each option. ® Parcels impacted: The total number of parcels impacted by each option. 5. Estimated Cost The estimated construction cost for each concept was based on preliminary design of a four -lane roadway with raised concrete median, turn lanes at major intersections, and a rural cross - section or an urban cross - section. Costs were developed for grading, pavement, retaining walls, storm sewer and other major items. A 15% contingency for other construction costs was included in each estimate. The costs are reported with a dollar value and a percentage increase /decrease from the baseline cost. The estimated right of way costs were developed based on Scott County 2002 appraised values with a 1.5 factor for each property. A. Dean Lake Area Three options were identified and evaluated for this area from east of CSAH 18 to McKenna Road. CSAH 16 Corridor Planning Study Page 26 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 ® Existing alignment. (Figure 3.1) ® Option Al — Shift CSAH 16 alignment south, using existing roadway as frontage road. (Figure S) ® Option A2 — Shift CSAH 16 alignment north maintaining south ROW line. (Figure 6) A comparison of each concept is discussed below: 1. Traffic Analysis The overall traffic operation of each concept is similar, operating at a LOS A, however, with the existing alignment options, several driveway accesses would be entering onto CSAH 16. Although these driveways would be restricted to right - in/right -out, they would pose safety concerns for westbound traffic with respect to potential crashes in the corridor. 2. Environmental Impacts Each concept would require specific attention to storm water runoff and its impacts to Dean Lake. No other environmental impacts exist in the area between CSAH 83 and McKenna Road. 3. Public Opinion A very strong public opinion was voiced in favor of Option Al - shifting the alignment to the south and creating the frontage road for the existing properties along CSAH 16. CSAH 16 Corridor Planning Study Page 27 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 4. Design Considerations Each alternative provided approximately the same horizontal and vertical design elements through the area. However, with the existing alignment and Option A2 alignment, operating speeds for westbound traffic would be slightly compromised with driveways directly accessing the roadway. 5. Right- of -WaV A 130 -foot right -of -way corridor was assumed for each option. Based on this, the following right -of -way concept comparison can be made. Tahle 6 Dean Lake Options Riaht- nf- -Wmv Cmmnaricnn * Includes total parcel areas of total takes. ** Any property where the primary structure is within 20 feet of future right -of -way. * ** 22 parcels are residents along the north side, 2 parcels are currently farmed on the south side. 6. Costs The estimated construction costs and right -of -way costs for each alternative are similar. This includes cost for grading, pavement, drainage, and other appurtenant work. The cost also includes a 15% contingency for other items not included in the estimate. The costs are _.. shown in 2002 dollars. The total costs and percent increase /decrease from baseline is shown in Table 7 below: CSAH 16 Corridor Planning Study Page 28 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 Option Al Option A2 Existing Shifted Alignment Shifted Alignment Alignment South North Area * 9.64 Acres 13.4 Acres 14.01 Total Takes ** 7 0 10 Parcels Im acted 24 * ** 2 22 * Includes total parcel areas of total takes. ** Any property where the primary structure is within 20 feet of future right -of -way. * ** 22 parcels are residents along the north side, 2 parcels are currently farmed on the south side. 6.

Other Issues Other issues exist between CSAH 83 and McKenna Road. These issues include: ® Mdewakanton Sioux Community Right -of -Way Acquisition: With any alignment option, right -of -way will be required from the Mdewakanton Sioux Community. Should right -of -way not be available from the Mdewakanton Sioux, the existing alignment (No Build) would be the only feasible option for the Dean Lake area. This would have substantial impacts to the residential community north of CSAH 16. 8. Preferred Concept Based on the above analysis, Option Al - shifted south alignment is preferred. CSAH 16 Corridor Planning Study Page 29 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 B. CSAH 18 Intersection Area Four realignment scenarios were developed for the CSAH 16 approaches to CSAH 18. Each scenario is shown in Figure 16 in Appendix A and is discussed in detail below. 1. Scenario 1— Phase l Existing Alignment / Phase 11 Existing Alignment This scenario includes reconstruction on existing alignments, both east and west of CSAH 18. This scenario is the baseline alignment. Traffic Analysis: A capacity and level of service analysis was conducted for the projected (2020) traffic volumes for this scenario. The results of the analysis are illustrated in Table 8.

Figure 17 illustrates the proposed intersection control and spacing for this scenario. It should be noted that even though the CSAH 18/134 Street intersection will likely not require installation of a signal by 2020, traffic volumes are likely to increase after 2020, as undeveloped areas continue to develop in and around Scott County. Therefore, a signal at this intersection sometime in the future is likely. This could create safety concerns, especially for northbound traffic approaching the intersection on a curved and downgrade approach. Environmental Review: The environmental review of this scenario found that no significant impacts would occur. Any wetlands impacted would require mitigation. Prior Lake channel impacts will require a permit. Drainage issues in the corridor would need to be addressed during the design of any project. Public Opinion: Public opinion of this scenario was mixed. The public's primary _. concern was with the impact to the existing properties through the CSAH 16 Corridor Planning Study Page 31 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 corridor. Other concerns included access to properties, drainage, and traffic control at the CSAH 16 intersections. Design Considerations: This scenario would meet a design speed of 55 MPH approaching CSAH 18 from the east or west. Horizontal and vertical alignments would meet all state design guidelines. No significant grading or retaining walls would be required. Right -of -way: The corridor from Foothill Trail to CSAH 18 and from CSAH 18 to Boone Avenue would require approximately 10.6 acres of right -of- way acquisition, impacting 47 parcels with 2 total takes. It is possible that the 2 total takes could be avoided with special design considerations. For example, curb sections could be incorporated where feasible to reduce the amount of right -of -way necessary to construct the new facility. Costs: The estimated cost for this scenario from Foothill Trail to CSAH 18 and from CSAH 18 to Boone Avenue is shown in Table 9: Table 9 Scenario Cost Cost %* Construction: $4,400,000 0 Right-of-Way: $800,000 0 Total — Scenario 1 $5,200,000 0 * % Increase/Decrease from baseline.

Scenario 2 - Phase 1 Existing Alignment / Phase 11 Option B This scenario includes reconstruction on existing alignment east of CSAH 18 and a realignment west from Boone Avenue to the north CSAH 16 intersection (Eagle Creek Boulevard). Traffic Analysis: A capacity level of service analysis was conducted for the projected (2020) traffic volumes for this scenario. The results of the analysis are illustrated in Table 10.

Figure 18 illustrates the proposed intersection control and intersection spacing. Environmental Review: The environmental review of this scenario found that no significant impacts would occur west of CSAH 18. However, east of CSAH 18, modest to high impacts occur to the bluff area and wooded areas. The Minnesota Department of Natural Resources (DNR) has reviewed this area for potential impacts. Their findings are outlined in the letter found in Appendix C. Based on their comments, several issues would need to be studied in detail with this alignment option. Drainage issues and impacts to Eagle Creek and Boiling Springs will need to be addressed during the design of any project. Public Opinion: Public opinion of this scenario was mixed. The public's primary concern was with the impact to the existing properties through the corridor. Other concerns included access to properties, drainage, impacts on environmental areas, and right -of -way acquisition. Design Considerations: This scenario would meet a design speed of 55 MPH approaching CSAH 18 from the east or west. Horizontal and vertical alignments would meet all state design guidelines. The vertical grade on _. CSAH 16 between CSAH 18 and Boone Avenue would range from CSAH 16 Corridor Planning Study Page 34 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 3% to 6 %. Significant grading and retaining walls would be required east of CSAH 18. Right -of -Way: The corridor from Foothill Trail to CSAH 18 and from CSAH 18 to Boone Avenue would require 23.6 acres of right -of -way acquisition, impacting 50 parcels with 5 total takes. It is possible that the 2 total takes east of CSAH 18 could be avoided with special design considerations. For example, curb sections could be incorporated where feasible to reduce the amount of right -of -way necessary to construct the new facility. Costs: The estimated cost for this scenario from Foothill Trail to CSAH 18 and from CSAH 18 to Boone Avenue is shown in Table 11: Table 11 Scenario 2 Cost Cost %* Construction: $6,600,000 +50% Right-of-Way: $2,000,000 +150% Total — Scenario 2 $8,600,000 +65% * % Increase/Decrease from baseline. 3. Scenario 3 - Phase I Option B2 / Phase 11 Existing Alignment This scenario includes reconstruction on existing alignment east of — CSAH 18 and realigning CSAH 16 west of CSAH 18 to Preserve Trail. CSAH 16 Corridor Planning Study Page 35 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 Traffic Analysis: A capacity level of service analysis was conducted for the projected (2020) traffic volumes for this scenario.

Figure 19 illustrates the proposed intersection controls and intersection spacing for Scenario 3. Environmental Review. The environmental review of this scenario found that no significant impacts would occur east of CSAH 18. However, west of CSAH 18, CSAH 16 Corridor Planning Study Page 36 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 modest to high impacts occur to the bluff area and wooded areas. Several wetland areas would be impacted west of CSAH 18. It is estimated that approximately four acres of wetlands would be disturbed. These wetlands would be mitigated based on state and federal wetland regulations. Drainage issues will need to be addressed during the design of this project. Public Opinion: Public opinion of this scenario was mixed. The public's primary concern was with the impact to the existing properties through the corridor. Other concerns included access to properties, drainage, impacts on environmental areas, and right -of -way acquisition. Design Considerations: This scenario would meet a design speed of 45 MPH approaching CSAH 18 from the west and 55 MPH from the east. Horizontal and vertical alignments would meet all state design guidelines. The vertical grade of CSAH 16 between Foothill Trail and CSAH 18 would be less than 5 %. Some grading would be required west of CSAH 18. Right -of -Way: The corridor from Foothill Trail to CSAH 18 and from CSAH 18 to Boone Avenue would require 56.7 acres of right -of -way acquisition, impacting 13 parcels with 1 total take. Costs: The estimated cost for this scenario from Foothill Trail to CSAH 18 and from CSAH 18 to Boone Avenue is shown in Table 13: CSAH 16 Corridor Planning Study Page 37 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 Table 13 Scenario 3 Costs Cost % * Construction: $4,800,000 +9% Right -of -Way: $1,100,000 +38% Total — Scenario 3 $5,900,000 +13% * % Increase/Decrease from baseline. 4. Scenario 4 — Phase 1 Option C / Phase 11 Existinq Alignment This scenario includes reconstruction on existing alignment east of CSAH 18 and reconstruction on a proposed realignment from Foothill Trail to the south CSAH 16 intersection west of CSAH 18. Traffic Analysis: A capacity level of service analysis was conducted for the projected (2020) traffic volumes for this scenario. The results of the analysis are illustrated in Table 14.

Although the operation of the CSAH 16 and CSAH 18 intersection in this scenario would operate at a level of service B, a concern with the safety of intersection would exist. This intersection would have three approaches with significant (5% or greater) downgrades to the intersection. The eastbound and westbound approaches and the northbound approach would all be downgrades to the intersection. This type of intersection would likely exhibit higher than average crash frequencies, especially during the winter months. Figure 20 illustrates the proposed intersection control and intersection spacing for this scenario. Environmental Review The environmental review for this scenario found that no significant impacts would occur east of CSAH 18. However, west of CSAH 18, modest to high impacts occurred to the bluff area and wooded areas. The Minnesota Department of Natural Resources (DNR) reviewed this area and provided comments as outlined in Appendix C. Based on those comments, more detail study should be made of the area, specifically west of CSAH 18 during any detail design consideration. Drainage issues will need to be addressed during the design of this prof ect. CSAH 16 Corridor Planning Study Page 39 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 Public Opinion The public's primary concern was the impact to the existing properties through the corridor and impacts on the environmentally sensitive areas west of CSAH 18. Other concerns included access to property, drainage, impacts on other environmentally sensitive areas, noise, property values, lighting, animal habitats, and right -of -way acquisition. Design Considerations This scenario would meet a design speed of 45 MPH approaching CSAH 18 from the west and 55 MPH from the east. Horizontal and vertical grades would meet all state design guidelines. The vertical grade on CSAH 16 between Foothill Trail and CSAH 18 would range from 2% to 6 %. Significant grading and retaining walls would be required west of CSAH 18. The Muhlenhardt Road intersection will require significant regarding. The proposed alignment would construct a new intersection on an already steep grade. Cutting Muhlenhardt Road off from the new alignment is not an option because of emergency access issues to existing residential areas. Right-of-Way The corridor from Foothill Trail to CSAH 18 and from CSAH 18 to Boone Avenue would require 26.3 acres of right -of -way acquisition, impacting 16 parcels with 2 total takes. Costs The estimated cost for this scenario from Foothill Trail to CSAH 18 and from CSAH 18 to Boone Avenue is shown in Table 15. CSAH 16 Corridor Planning Study Page 40 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 Table 15 Scenario 4 Costs Cost % * Construction: $7,400,000 Right-of-Way: $1,600,000 +168% +100% Total — Scenario 4 $9,000,000 +73% * % Increase/Decrease from baseline. Attached as Table 16 is a summary matrix of the four scenarios for the realignment of CSAH 16 at CSAH 18. The matrix outlines the evaluation criteria for each scenario. 5. Other Issues Other issues were identified and reviewed as part of the study. Each is discussed below: ■ CSAH 18 Overpass: An overpass was considered for the Scenario 4 alignment. Although this intersection would be set up very adequately for an overpass, providing access to and from CSAH 18 would require excessive right -of -way takings and estimated costs of over $5 million for just the interchange. This alternative was dismissed as a result of this evaluation. 6. Preferred Concept Based on evaluation criteria and input from the public and each city, the preferred alternative which most closely satisfies the goals of the CSAH 16 corridor would be Scenario 2 — Phase I Existing Alignment/ Phase II Option B. Scenario 2 is the best alignment for CSAH 16 to address future safety and efficiency issues along both CSAH 16 and CSAH 16 Corridor Planning Study Page 41 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 CSAH 18; although as documented in this report, it comes with a higher cost ($3,400,000) than the existing alignment, and has potential for more environmental impacts. C. TH 13 Approach Area Based on the issues discussed in Section IV, three options were identified and evaluated for this area from Boone Avenue to TH 13. • Existing alignment. • Option Cl - Shift CSAH 16 alignment north to improve grade on CSAH 16. • Option C2 — Shift CSAH 16 alignment north of the cemetery from TH 13 to Boone Avenue. A comparison of each concept is discussed below: 1. Traffic Analysis The overall traffic operation of each concept is similar, operating at a level of service A. 2. Environmental Impacts Each concept would require specific attention to storm water runoff and its impacts to Eagle Creek. No other environmental impacts exist in the area between Boone Avenue and TH 13. 3. Public Opinion Comments were received in favor of shifting the alignment to the north, if it could reduce the grade of CSAH 16 approaching TH 13. This could benefit adjacent development as well as vehicles using CSAH 16. CSAH 16 Corridor Planning Study Page 42 Cities of Shakopee and Savage Scott County. Public Works Division WSB Project No. 1383 -00 4. Design Considerations The steepest existing grade on CSAH 16 approaching TH 13 is approximately 8.6% for a distance of approximately 800 feet. By shifting the roadway to the north, the steepest grade does not significantly change, however, the length of the grade is reduced to approximately 300 feet. The horizontal design speed for the existing alignment option is 55 MPH. Whereas, the horizontal design speed for the shifted alignment is 45 MPH. 5. Right- of -Way A 130 -foot right -of -way corridor was assumed for both options. Based on this, the following comparison can be drawn. Table 17 TH 13 Approach Options 6. Costs The estimated construction costs for both alternatives is similar. The estimated cost for CSAH 16 from Boone Avenue to TH 13 would be as outlined in Table 18. This includes cost for grading, pavement, drainage, and other appurtenant work. The right -of -way costs for the concept are estimated at $100,000 for existing alignment, $200,000 for Option C1, and $500,000 for Option C2.

Preferred Concept Based on the above analysis, the shifted alignment option (Option Cl) is preferred. Although this alignment would not improve the grade to TH 13 significantly, some improvement would occur. This alternative could be implemented in coordination with proposed development on the north side of CSAH 16. CSAH 16 Corridor Planning Study Page 44 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 As discussed previously, the purpose of this study was to provide a planning level analysis to determine the future configuration of CSAH 16 between CSAH 83 and TH 13. The study will provide Scott County as well as the Cities of Shakopee and Savage with a tool to use as development occurs in the corridor area. The implementation of the adopted study will occur as development is approved along the corridor. No time frame has been established for the implementation nor has funding been secured for any portion of the improvements. It is anticipated that implementation would occur in Phases (i.e. CSAH 83 to future CSAH 21, etc.), as development occurs, as traffic levels increase, and as funding becomes available. Several funding sources would be available to finance improvements in the corridor. These include: County State Aid/ Municipal State Aid Funds: County State Aid and Municipal State Aid (Gas tax money) is available to each city and county to fund roadway improvements designated on their State Aid System. The roadways are required to meet specific standards in order to use allocated funding. CSAH 16 is a County State Aid route in which each city could also use their Municipal State Aid funds. Assessments: Each city would have the opportunity to assess any specific roadway _ improvements benefiting the adjacent properties. Typically, roadway improvements that have been accelerated due to development or require CSAH 16 Corridor Planning Study Page 45 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 additional geometries would be a developer responsibility and could be assessed through the cities. Federal Funding: Although currently this roadway is designated as a B -Minor Arterial and is not eligible for federal funding, it is anticipated that with a continuous east -west connection from CSAH 83 to TH 13, a case could be made that this roadway is a reliever to principal arterials TH 169 /TH 13 and CSAH 42. This roadway then could be re- designated as an A -Minor Arterial Reliever and federal funding could be applied for. This funding source is allocated based on need through a competitive process. There are no guarantees that this funding would be available for this roadway. Local Funds: Each agency can designate capital improvement funds for improvements to CSAH 16. Typically, funds are allocated to the projects in a five -year time frame. None of these projects are currently included in any capital improvement programs. Therefore, the earliest this funding source could be used would be fiscal year 2008. CSAH 16 Corridor Planning Study Page 46 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 Findings 1 Recommendations The County identified the need for a planning level study of CSAH 16 to better define future design and right -of -way needs in the corridor. It should be noted that no funding has been set aside in the County's current (2002 -2006) 5 -Year Capital Improvement Program to reconstruct CSAH 16. A. Study Findings Findings of the CSAH 16 corridor planning study from CSAH 83 in the City of Shakopee to TH 13 in the City of Savage include the following: 1. The City of Shakopee had identified improvements to the CSAH 16 /CSAH 83 intersection to line up with the future extension of 17th Avenue to the west as part of their Transportation Plan. Recent development proposals in the northeast quadrant of CSAH 83 at CSAH 16 intersection have initiated implementation of those improvements. 2. The existing (2000) average daily traffic (ADT) volumes on CSAH 16 between CSAH 83 and CSAH 18 range from 2,350 - 3,250 vehicles per day. Existing 2000 (ADT) volumes on CSAH 16 between CSAH 18 and TH 13 range from 4,050 - 4,300 vehicles per day. Based on the County's Transportation Plan, the projected 2020 traffic volume between CSAH 83 and CSAH 18 will range from 12,500 - 15,000 vehicles per day. The projected 2020 traffic volume between CSAH 18 and TH 13 is expected to be 9,500 vehicles per day. 3. Based on current 2020 traffic projections, it will become necessary for CSAH 16 to be improved to a four -lane divided facility in the future from CSAH 83 to CSAH 18. A four -lane rural section with raised median from McKenna Road to CSAH 18 would allow all drainage to be conveyed in ditches, thereby minimizing the costs required to install a storm sewer CSAH 16 Corridor Planning Study Page 47 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 system. The right -of -way required for a four -lane rural section along this roadway segment would be 150 feet. 4. Based on current 2020 traffic projections, it will not become necessary for CSAH 16 to be improved to a four -lane divided facility by 2020 between CSAH 18 and TH 13 for safety or capacity reasons. But, because of recent and anticipated land use changes in the area, and because traffic on this segment is expected to continue to grow after 2020, a four -lane facility should be planned for. If this segment is reconstructed, a four -lane urban section from CSAH 18 to TH 13 will be required because of existing development and topography. The right -of -way required for a four -lane urban section along this roadway segment would be 130 feet. 5. Several environmentally sensitive areas exist through the corridor. They include: Dean Lake Area Wetland/Floodplain Areas Prior Lake Channel Wooded Areas Bluff Areas Eagle Creek Boiling Springs 6. There has been an ongoing concern with the grade of CSAH 16 approaching TH 13. In addition, issues have been raised by the City of Savage on future access along the corridor, specifically to the north of CSAH 16. 7. Several alignment issues exist along the corridor. They include: CSAH 16 Corridor Planning Study Page 48 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 ® Dean Lake Area On the north side of CSAH 16, between CSAH 83 and McKenna Road, there are currently 16 private driveway access points and 3 public street access points along a 3000 foot segment. In addition, widening CSAH 16 in this area along the existing alignment would potentially require the total acquisition of 7 residential parcels. Land along the south side of CSAH 16 in this area is currently being used for agricultural purposes. ® CSAH 18 Area Currently, CSAH 16 intersects CSAH 18 at two intersections approximately 1 /4 mile apart. This discontinuity raises safety and efficiency issues for both east -west traffic on CSAH 16 and north- south traffic on CSAH 18. This study therefore reviewed four alignment options with respect to traffic, the environment, design, right -of -way, and estimated costs. A comparison of these alignment scenarios is presented in Table 16. Scenario 1: Phase I - Existing Alignment, Phase II -Existing Alignment This alignment leaves the discontinuity in CSAH 16, meaning CSAH 18 and CSAH 16 will continue to intersect at two locations. It is likely that the southerly intersection will eventually require signalization, which would become a safety concern because of the curve and the slope of the roadway for northbound CSAH 18 traffic as it approaches the intersection. This scenario has the least cost, and least amount of environmental impact. Scenario 2: Phase I - Existing Alignment, Phase If - Option B This alignment makes CSAH 16 a continuous east -west route, and eliminates a full access intersection (CSAH 18 & 134 Street), making it CSAH 16 Corridor Planning Study Page 49 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 the safest and most efficient scenario. Although based on 2020 projections, it is not anticipated that the current southerly intersection of CSAH 18 & CSAH 16 would require signalization by 2020, as northern Scott County continues to develop, this intersection will eventually require signalization if CSAH 16 is not realigned. This scenario addresses that future safety concern. When compared with Scenario 1, the costs between Foothill Trail and Boone Avenue for this scenario would be increased by 65% mainly due to right -of -way acquisition and due to the costs of building the roadway through the bluff area. This alignment affects an area designated by the Minnesota Department of Natural Resources as "moderately" significant for biodiversity, would impact wooded areas, bluff areas, and more detailed analysis of how to minimize impacts to Boiling Springs and Eagle Creek would be required at the time of more detailed environmental assessment and roadway design. Scenario 3: Phase I - Option B2, Phase II - Existing Alignment This scenario eliminates the existing full access location at the north intersection of CSAH 18 & CSAH 16 (Eagle Creek Boulevard), and combines it with the existing full- access intersection at CSAH 18 & Preserve Trail. This scenario creates a longer segment of roadway shared by CSAH 18 & CSAH 16, and does not address the potential safety issue at the south intersection of CSAH 18 & CSAH 16. When compared with Scenario 1, the costs between Foothill Trail and Boone Avenue for this scenario would be increased by 13 %. This scenario would impact wooded areas, bluff areas, and wetlands. Scenario 4: Phase I - Option C, Phase II - Existing Alignment This alignment makes CSAH 16 a continuous east -west route, and eliminates a full access intersection (CSAH 18 & Eagle Creek Boulevard); CSAH 16 Corridor Planning Study Page 50 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 but this alignment also creates other transportation problems. The intersection of CSAH 18 & CSAH 16 would include 3 downgrade approaches to this signal, and in addition to the 6% downgrade approach to the intersection, northbound traffic approaches the intersection in a curve, reducing sight distance to the intersection. This alignment also creates a problem with Muhlenhardt Road. Because of vertical grades, it would be difficult to construct a full access intersection of CSAH 16 and Muhlenhardt Road, thereby creating a problem for some residents to access their homes if Muhlenhardt is slippery. This also becomes an issue for emergency response. When compared with Scenario 1, the costs between Foothill Trail and Boone Avenue for this scenario would be increased by 73 %. This scenario would impact wooded areas and bluff areas. . TH 13 Area Currently, CSAH 16 west of TH 13 includes a vertical grade of 8.6% for 800 feet. This slope is steeper than preferred, and can create safety issues during the winter. By shifting the roadway to the north (Option C1) between the cemetery and TH 13, the steepest portion of this vertical grade can be reduced from 800 feet in length to 300 feet. Continuing a northerly alignment past the cemetery (Option C2) does not allow the vertical grade to be reduced any further. 8. Baseline cost estimate for a four -lane roadway between CSAH 83 and CSAH 18 is $11,100,00, including right -of -way. The baseline cost for CSAH 18 to TH 13 is $3,700,000, including right -of -way. The increase in cost for each alignment alternative in the area of CSAH 18 ranges from5 % -26% of the total baseline cost for the whole CSAH 16 corridor, or 13 % -73% of the total baseline costs between Foothill Trail and Boone Avenue, depending on the alignment option. CSAH 16 Corridor Planning Study Page 51 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 9. Three future ponding locations and the total area necessary for each location to handle future roadway drainage were identified for Phase I. Two future ponding locations and the total area necessary for each location to handle future roadway drainage were identified for Phase II. 10. To help in addressing future funding issues, the County does have the option of applying for "A" Minor Arterial designation by Metropolitan Council to make it eligible for federal funding. B. Recommendations Based on the above findings and the analysis found in this study, the following recommendations are made: 1. Construct alignment Option Al in the Dean Lake area, which shifts future CSAH 16 south and maintains the existing CSAH 16 as a frontage road. 2. Maintain existing CSAH 16 alignment between McKenna Road and CSAH 18. 3. Plan for future realignment of CSAH 16 east of CSAH 18 consistent with Scenario 2, which realigns CSAH 16 from CSAH 18 east to Boone Avenue to the north to line up with CSAH 16 (Eagle Creek Boulevard). 4. Maintain existing CSAH 16 alignment from Boone Avenue to east of the cemetery on existing alignment. 5. Plan for future realignment of CSAH 16 from just east of the cemetery to TH 13 consistent with Option C1, which shifts the alignment slightly north to improve the vertical grade of CSAH 16, and allows better access to CSAH 16 from the currently undeveloped property north of CSAH 16 and west of TH 13. CSAH 16 Corridor Planning Study Page 52 Cities of Shakopee and Savage Scott County Public Works Division WSB Project No. 1383 -00 6. As development occurs along the corridor, secure right -of -way for roadway and ponding purposes consistent with the findings of this study. 7. Work with cities and developers on future ponding areas along the corridor to accommodate future drainage. 8. Submit a request to change the classification of CSAH 16 to a "A" minor arterial for potential federal funding.

The study is being conducted in two phases: CSAH 16 from CSAH 83 to CSAH 18, and CSAH 16 from CSAH 18 to TH 13. Scott County is seeking the public's reaction to future road design concepts for CSAH 16. This will be a follow up to the first open house held in October, where the public raised issues regarding traffic safety, road right -of -way, and the environment. Information regarding the design concepts will be available for viewing, including maps showing future right -of -way needs, possible realignment options (shown at right), and environmental issues. / D Q p 18 3 3 E E i .VD. ° 16 r•.

Scott County, in partnership with the City of Shakopee, is conducting a study to better define the future design and right -of -way needs along CSAH 16 (Eagle Creek Boulevard) from CSAH 83 to CSAH 18. A map showing the project corridor is included on the back of this handout. The purpose of the study is to provide a planning tool to assist the City and County in: • Maintaining /managing/improving the regional and local highway systems; • Providing reasonable and safe access to the residents in the area; • Improving the safety of the facility for corridor users; • Providing for roadway capacity now and in the future; and • Avoiding /minimizing and mitigating any environmental impacts associated with any improvements. WHAT IS THE TRAFFIC HISTORY IN THE CORRIDOR? The existing (2000) average daily traffic volumes in the corridor range from 2,350 vehicles per day west of CSAH 18 to 3,250 vehicles per day east of CSAH 83. The projected 2020 traffic volumes in the corridor range from 12,500 to 15,000 vehicles per day. This is above the capacity of a 2 -lane urban roadway, which CSAH 16 will become as Shakopee and Savage continue to develop. WHAT IS THE PURPOSE FOR THE OPEN HOUSE? This public information meeting is the first step in the development phase of the project. Scott County is seeking the public's input in identifying issues along CSAH 16, and all interested parties will have the opportunity to ask questions, express concerns, and raise issues along the study segments. WHAT IS YOUR ROLE IN THE STUDY? You are being requested to provide input and comments on any issues related to this roadway corridor. Scott County and the City will use this information to assist in the development of alternative concept layouts. Additional public meetings will be held following the development of the concept layouts at which time the public will have the opportunity to comment further on the alternatives. WHAT IS THE PROJECT SCHEDULE? The project is currently in the development phase of the study. The next step will be to develop alternative concept layouts, which will be presented to the public for comment. A preferred alternative will then be developed and ultimately approved by Scott County. Project documentation, including development of alternatives, an environmental review, and an approved concept layout, will be completed by January 2002_ There are no current plans to reconstruct CSAH 16 in the County's Capital Improvement Program.

Based on this review, there are 39 known occurrences of rare species or natural communities in the area searched (for details, see enclosed database printout and explanation of selected fields). Following are specific comments for only those elements that may be impacted by the proposed project. Rare feature occurrences not listed below are not anticipated to be affected by the proposed project. An area identified by the Minnesota County Biological Survey as a "Site of Biodiversity Significance" is located between CSAH 16 and Highway 169 within Sections 10 -12, 14 & 15 T115N R22W. This site contains several natural communities including Emergent Marsh, Dry Prairie, Oak Woodland- Brushland, and Oak Savanna, and supports the Rhombic- Petaled Evening Primrose (Oenothera rhombipetala), the Plains Pocket Mouse (Perognathus flavescens), and the Gopher Snake (Pituophis catenifer), all species of Special Concern (please see the enclosed maps for more detailed locational information). Oak Savannas once covered 5.4 million acres in the state. Currently, only 4,400 acres or 0.1% of the historical acreage remains in Minnesota. Prairie communities claimed 18 million acres of Minnesota in the 1850s, and now there are fewer than 150,000 acres; a loss of 99 %. Over a quarter of all listed species (26 %, or 114 species) in Minnesota occur in oak savannas and prairies; therefore, further loss of these habitats may threaten the continued survival of many plants, animals, and insects in the state. We recommend that any improvements and/or realignment of CSAH 16 avoid any remnants of these ecologically important and rare community types. Several other areas identified by the Minnesota County Biological Survey as "Sites of Biodiversity Significance" are located north of CSAH 16 between CSAH 18 and TH 13 in Section 18 TI 15N R2 1W, near Eagle Creek, a designated trout stream. These sites contain Wet Meadow, Willow Swamp, Dry Oak Savanna, and Lowland Hardwood Forest Natural Communities and provide habitat for the Plains Pocket Mouse and the Gopher Snake. We DNR Information: 651- 296 -6157 . 1- 888 -646 -6367 • TTY: 651- 296 -5484 . 1- 800 - 657 -3929 An Equal Opportunity Employer ®' Printed on Recycled Paper Containing a Who Values Diversity Minimum of 10% Post - Consumer Waste recommend that any improvements and/or realignment of CSAH 16 avoid fragmenting these significance sites (please see the enclosed maps for more detailed locational information). Activities in road rights -of -way can affect nearby rare communities. These effects are of particular concern due to the increasing threat posed by exotic plant species to native plant communities. I would therefore like to offer the following recommendations which would be applicable to any alignment alternative or improvement project that is considered further. Spoil should be placed as close to the existing right -of way as possible and not within any identified natural community or "Site of Biodiversity Significance ". Procedures should be implemented to ensure that eroded materials and runoff resulting from the project are controlled. Soil disturbance creates an environment in which invasive non - native plant species can become established. This allows them to more easily invade adjacent native habitats, where they displace native species. Therefore, immediately following construction, we would prefer that disturbed areas be planted with prairie species native to Minnesota, or some other non - invasive cover. The Natural Heritage database is maintained by the Natural Heritage and Nongame Research Program, a unit within the Division of Ecological Services, Department of Natural Resources. It is continually updated as new information becomes available, and is the most complete source of data on Minnesota's rare or otherwise significant species, natural communities, and other natural features. Its purpose is to foster better understanding and protection of these features. Because our information is not based on a comprehensive inventory, there may be rare or otherwise significant natural features in the state that are not represented in the database. A county -by- county survey of rare natural features is now underway, and has been completed for Scott County. Our information about natural communities is, therefore, quite thorough for that county. However, because survey work for rare plants and animals is less exhaustive, and because there has not been an on -site surv'ey of all areas of the county, ecologically significant features for which we have no records may exist on the project area. The enclosed results of the database search are provided in two formats: index and full record. To control the release of locational information which might result in the damage or destruction of a rare element, both printout formats are copyrighted.

S RANK [State Rank]. A rank assigned to the natural community type which reflects the known extent and condition of that community in Minnesota. Ranks range from 1 (in greatest need of conservation action in the state) to 5 (secure under present conditions). A "T' following a rank indicates little information is available to rank the community. Communities for which information is especially scarce are given a "U ", for "rank undetermined ". The ranks do not represent a legal status. They are used by the Minnesota Department of Natural Resources to set priorities for research, inventory and conservation planning. The state ranks are updated as inventory information becomes available.

IN ,I Memorandum CASE LOG NO.: 02 -011 TO: Mayor and City Council Shakopee Planning Commission Mark McNeill, City Administrator FROM: R. Michael Leek, Community Development Director SUBJECT: Joint Discussion Between the City Council and Planning Commission Regarding an Amendment to City Code Section 11.50, Planned Unit Development District, Subd. 5, Design Standards, and Subd. 6, Special Provisions for Planned Unit Developments MEETING DATE: May 14, 2002 At its April 16, 2002 meeting the Council tabled consideration of the proposed PUD text amendment in order to first have a joint discussion with the Planning Commission about what the Council and Board wish to accomplish with future PUDs. Attached for the Council and Commission's information is a copy of the April 16 memorandum to the Council. / I 1 At the conclusion of the discussion Council is asked to provide direction regarding the following; 1. Whether to schedule consideration of the proposed PUD text amendment for consideration at the Council meeting of May 21, 2002. 2. Possible modifications to the proposed PUD text amendment agreed to by the Council and the Planning Commission. 3. Other, possibly related items the Council and/or Commission wishes to have staff address or about which additional information is desired. R. Michael Leek Community Development Director g:\cc\2002\05-14wksp\txtpud.doc CITY OF SHAKOPEE Memorandum CASE LOG NO.: 02 -011 TO: Mayor and City Council Mark McNeill, City Administrator FROM: R. Michael Leek, Community Development Director SUBJECT: Amendment to City Code Section 11.50, Planned Unit Development District, Subd. 5, Design Standards, and Subd. 6, Special Provisions for Planned Unit Developments MEETING DATE: April 16, 2002 EXTRODUCTION: i During the development moratorium that was imposed M' ,J9. 9,9 and in response to the types and rate of development that were occurring, the City's PUD ordiriance;was revised. The revisions made at that time significantly limit the types of variations that can be allowed by the City Council in a PUD in the City of Shakopee. A copy of current City Code Sec. 11.50, Subd. 5 is attached for the to the February 7, 2002 report to the Planning Commission for the Council's information. Of most significance is the following provision; "No other variations to the design standards of the underlying zone shall be allowed in the PUD approval process" (City Code Sec. 11.50, Subd. 5, E., last paragraph) . This approach, which severely limits the Council's flexibility in approving variations as a part of a PUD approval is inconsistent with the philosophical underpinnings of the PUD as a planning and zoning tool, and is also inconsistent with the stated purpose of Shakopee's PUD ordinance, which is as follows; Subd. 1. Purpose. It is the purpose of the planned unit development overlay district (PUD) to encourage innovation, variety, and creativity in; site planning and architectural design; to promote flexihility in land development and redgyelopment, to maximize development compatibility; to encourage the planning of large parcels of land as a unit, to preserve and protect environmentally sensitive site features and historically significant features; to preserve open space•, to provide quality living, working, shopping and recreating environments for residents and visitors. (italics added) As the Commission and Council have seen with the concept plan for Ryan's development of the Valley Green Corporate Center site, the previously cited provision (Subd. 5, E) would require that each variation from the underlying districts' design standards would require an analysis based on the variance provisions of the City Code before a PUD. approval could be reached. While the Ryan project poses the most immediate challenge, it is expected that PUD review of future projects that z may be proposed in the in the bluff/wooded areas of the City could be adversely affected by the current limitations in flexibility in PUD ordinance. For the reasons stated above, staff developed the following amendments for consideration by the Planning Commission and City Council. • Subd. 5. Design Standards A.

In reviewing requests for increases in density or variations from other requirements beyond that allowed in the underl dung district the Council may take into account the following factors 0 of the pr-ejeet afea; 1. That the open space proposed in the PUD exceeds the minimum required by this subdivision; 2. Geologic and/or topographic features unduly restrict development opportunities on 30% or more of the gross project area.} 3. Environmental features exist on the site and the variations are necessary to preserve natural features. Environmental features may include but are not limited to the following defined features, A. Slopes in excess of 4:1, B. Tree cover measuring six 6) inches in diameter and /or six (6) feet in height covering; 20% or more of the gross project site, C. The existence of wetlands, lakes, marches, streams, springs or other natural water bodies. B. Open space: a planned unit development, which includes dwellings, shall provide at least 15% of the project area as open space. If the planned unit development is to be 2 developed in phases, the applicant must include the entire site in the plat of the first phase of development and designate public open space. Open space is a landscaped area or areas available for the common use of and is accessible by all residents or occupants of the buildings within the planned unit development. Open space shall be calculated on a net basis which excludes private yards, private streets from back of curb to back of curb, public rights -of -way, any areas within an easement or any other non- recreational impervious surface area. Dedicated parkland shall not be used iii calculating open space for a development. The applicant shall be required to submit, along with the PUD site plan, an open space plan illustrating the use and/or function of the open space area or areas. The open space plan shall include any proposed improvements and/or design of the open space area. Private yards shall be defined as that portion of a lot not occupied by a structure and under the ownership and /or control of the individual property owner or those areas adjacent to the residential units which are typically viewed and/or utilized by the occupants of the residential units as an extension of their dwelling unit. There shall not be any credit given to the open space requirements. C. (Deleted, Ord. 544, April 15, 1999) D.

S ubd 6 Special Provisions for Planned Unit Dev elopments. A. Criteria for Granting a Planned Unit Development Application. The City Council shall base its decision to grant or deny an application for a planned unit development upon the following factors: 1. Whether the proposed development is consistent in all respects with the comprehensive plan and with this Section; 2. Whether the proposed development, including deviations from design standards of the underlying zones, is compatible with surrounding land uses; 3. Whether the proposed development, including deviations from development standards of the underlying zone, provides adequate open space, circulation, parking, recreation, screening, and landscaping; 4. Whether the primary function of the PUD is to encourage development that will preserve and enhance the worthwhile, natural terrain characteristics and not force intense development to utilize all portions of a given site in order to arrive at the maximum density allowed. In evaluating each individual proposal, the recognition of this objective will be a basic consideration in granting approval or denial; 5. Whether there exists an overall compatibility of land uses and over appearance and compatibility of individual buildings to other site elements or to surrounding development: However, the architectural style of buildings shall not solely be a basis for denial or approval of a plan. City Code states that the City Council may grant a zoning ordinance amendment when it finds that one or more of the following criteria exist. Staff has prepared draft findings for the Council's consideration: Criteria #1 That the original zoning ordinance is in error; Finding #1 The original zoning ordinance is in.. not in error. Criteria #2 That significant changes in community goals and policies have taken place; Finding #2 Significant changes in community goals and policies have taken place. Specifically, the City of Shakopee desires to promote development that does a better job of preserving open space, ecological systems and values, and providing life -cycle housing opportunities within the City. Criteria #3 That significant changes in City -wide or neighborhood development patterns have occurred; or Finding #3 Significant changes in development patterns have occurred Because of demographic and market trends, the City of Shakopee has been presented with an increasing number of proposals for mixed use developments This type of development can require more flexibility than is afforded by traditional zoning districts if community values of open space, environmental preservation and enhancement, and life cycle development are to be preserved Criteria #4 That the Comprehensive PIan requires a different provision. Finding #4 The Comprehensive Pkm does not require a d ferent provision. ALTERNATIVES: 1. Approve Ordinance No. as presented, and direct the appropriate City officials to publish the summary of the ordinance in the City's official newspaper. 2. Approve Ordinance No. with revisions, and direct the appropriate City officials to publish the summary of the ordinance in the City's official newspaper. 3. Deny the proposed amendments, and direct staff to prepare a resolution with findings relative to the denial for action at the next, regularly scheduled City Council meeting. 4. Table the matter, and request additional information. PLANNING COMMISSION RECOMMENDATION: The Planning Commission reviewed the proposed ordinance amendment on February 7, 2002, and recommended that the City Council approve the proposed changes. Should the Council do so, the Planning Commission would like to schedule a joint meeting with the City Council to discuss, and reach consensus on, what the City is seeking from PUDs.

Michael Leek Community Development Director g Acc\2002 \05- 14wksp\MUSA. doc (0.0'_ I ' r , � TO: Mayor and City Council Planning Commission Mark McNeill, City Administrator FROM: Julie Klima, Planner Review Process DATE: May 14, 2002 DISCUSSION Historically, the City of Shakopee has processed land use applications sequentially rather than simultaneously, even though the sequential review is not mandated by the City Code. For instance, if a developer were to file applications for a rezoning, Planned Unit Development (PUD), preliminary plat, and final plat, the following would be the review schedule (using 2002 application and meeting dates). Application Date Submitted PC Review CC Review Rezoning May 2 June 20 July 2 PUD July 3 August 22 Sept. 3 Prelim. Plat August 29 October 17 Nov. 6 Final Plat Nov. 21 N/A Jan. 7, 2003 Therefore, the best case scenario (all dates assume recommendations /actions taken without the need for continuance or tabling for further information) would require a total of approximately 8 months to work through the review process. In discussions with developers /property owners, quite often it has been brought to the attention of staff that a great number of other communities allow an abbreviated process which combines the review of various applications but concludes with final actions in a specific sequential order. Using the example noted above, applications for all 4 processes could be received on May 2. The applications would then proceed to a public hearing before the Planning Commission (if applicable) on June 20. At that point, the review of the applications would proceed accordingly. The City Attorney has noted that a single public hearing can be held on several items with the opportunity for individual sequential action. The City Attorney further stated that a public hearing can be closed for one item (for instance, the rezoning) but be kept open for other items (PUD, Preliminary Plat) if necessary. Obviously, such a process requires a significant amount of work and investment on behalf of the applicant prior to making application. Along with this investment, there would an inherent risk on the part of the applicant relative to the City's reception of the submitted proposals. At this point in time, staff is seeking direction from the City Council/Planning Commission regarding the preferred approach to the application process. If the Council/Commission is interested in pursuing a simultaneous review of applications, staff can work toward a text amendment addressing simultaneous review with sequential actions. However, should the Council/Commission prefer the individual review of applications, staff suggests that a text amendment be directed for preparation to solidify the City's position. The text amendment could include language allowing the simultaneous review of applications with Council's approval.
