Memorandum CASELOG NO.: 03-077 TO: Honorable Mayor and City Council Mark McNeill, City Administrator FROM: Mark Noble, Planner I SUBJECT: Preliminary Plat of Riverside Fields MEETING DATE: August 19, 2003 REVIEW PERIOD: June 6, 2003 - October 3, 2003 INTRODUCTION: Ryland Homes has submitted an application for variances to the lot width, side yard setback, and rear yard setback, in conjunction with a preliminary plat of property located west of CSAH 18 and south offuture CSAH 21. CONSIDERATIONS: The applicant is proposing a mixed-use development that would consist of single- family residential lots (66 acres), office use and neighborhood commercial (10 acres), and wetlands (3.5 acres). Additionally, as part of the application, the applicant is requesting approval of variances to the lot width requirement (50 feet minimum, where 60 feet minimum is required), and 15 feet side yard setbacks between structures, where 20 feet minimum is required. The original application had included a variance request for 20-foot rear yard setbacks, where 30 feet is the minimum rear yard setback requirement. The rear yard setback variance request for the properties on the north side of the east/west street has been withdrawn by the applicant, and they will work with potential builder(s) to design structures that comply with the rear yard setback requirements for that area. The applicant has submitted revised drawings (dated 8-7-03) that reflect the street and right-of- way width for the east/west street, as suggested by staff. They have also provided street names which staffwill be evaluating. Additionally, staff just received additional information from the applicant (dated 8-13-03), which we have not had an opportunity to share with other city staff and respond to, but is included for the Council's review. ALTERNATIVES: 1. Approve Resolution No. 5916, a resolution approving the preliminary plat of Riverside Fields, subject to the conditions as proposed. 2. Approve Resolution No. 5916, a resolution approving the preliminary plat of Riverside Fields, subject to revised conditions. 3. Deny the preliminary plat of Riverside Fields. 4. Table a decision in order to allow time for the applicant and/or staff to provide additional information. PLANNING COMMISSION RECOMMENDATION: The Planning Commission reviewed this project at their August 7, 2003 meeting, and by a 4 to 2 vote, recommended approval of the preliminary plat with a variance only to allow 55' lot widths for lots north of the east/west street, and with a sidewalk on the north and south sides of the east/west street. The staff report to the Commission is attached for the Council's information. ACTION REQUESTED: Offer a motion to approve Resolution No. 5916, a resolution approving the preliminary plat of Riverside Fields, subject to the conditions as proposed. ~ " Planner I RESOLUTION NO. 5916 A RESOLUTION OF THE CITY OF SHAKOPEE, MINNESOTA APPROVING THE PRELIMINARY PLAT OF RIVERSIDE FIELDS WHEREAS, Ryland Homes, applicant, and Shakopee Crossings Limited Partnership, property owner, have made application for Preliminary Plat approval ofRNERSIDE FIELDS; and WHEREAS, the subject property is legally described as follows: All that part of the Northwest Quarter of Section 13, Township 115, Range 20, Scott County, Minnesota, lying southwesterly ofthe southwest right-of-way line of County State Aide Highway No. 18, and southeasterly of the southeast right-of-way line at County Road 21; and WHEREAS, the Shakopee Planning Commission reviewed and recommended approval of the Preliminary Plat on August 7, 2003; and WHEREAS, all required public notices regarding the public hearing were duly sent and posted and all persons appearing at the hearing have been given an opportunity to be heard; and WHEREAS, the City Council of the City of Shakopee did review the Preliminary Plat of Riverside Fields on August 19,2003; and NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF SHAKOPEE, MINNESOTA, as follows: That the Preliminary Plat ofRNERSIDE FIELDS is approved subject to the following conditions: I.

Additional storm drainage calculations need to be submitted including the 100- year and 10-day snowmelt event. THEREFORE, BE IT FURTHER RESOLVED, that approval of the Preliminary Plat of RIVERSIDE FIELDS does not constitute a representation or guarantee by the City of Shakopee as to the amount, sufficiency or level of water service that will be available to lots within the plat as they are developed. Adopted in session of the City Council of the City of Shakopee, Minnesota, held the _ day of , 2003. Mayor of the City of Shakopee ATTEST: ~~m;lED\ll~~ RYLAND ~~ AUG 1 4 2003 August 13,2003 By ~~ ~,.._-.-=-...~ The Ryland Group, Inc. 7900 West 78th Street Mayor and City Councilmembers: Suite 100 Edina, MN 55439 Contractor's Lie # 20035443 Ryland Homes is pleased to bring you a 211 lot single-family developme.lltyllGlCated south and west of our Riverside Grove town home and condominium neighborhood, west of County Road 18 and south of future County Road 21. Over the past year, we have been listening to your concerns and are trying hard to develop a single-family neighborhood on a zoned property that would otherwise allow up to 640 units. There are difficulties in doing this and we need your help to succeed. We think that we are responding correctly to Shakopee's needs with regard to land-use, open space, recreation, and environment. Weare either meeting or exceeding City requirements and we need some flexibility in the City Code in order to make it all work. None of the variances result in a change to the City Code that Shakopee has not approved previously. Ifwe are successful, we will develop 211 traditional single-family homes and 10 acres of neighborhood commercial and office in conformance with the PRD zoning designation. Because of the physical characteristics of the site, which create a hardship for reasonable use of the land as single-family, we are requesting some flexibility in the lot setbacks, and on a limited basis, the lot width. Because of the elevation of this site as it relates to the City's Comprehensive Storm-water Management Plan, there is an extraordinary amount of fill required to develop this property as single-family. Attached is substantiation for the requested variances according to the City's Criterion. Weare working hard to provide the best housing diversity to the neighborhood by also cooperating with Shakopee Crossings, and Centex Homes in the development of the property. The project as proposed is viable, but, if all of the recommendations of the City Advisory Commissions are combined, and the variances are not granted by the City Council, there will be a loss of lots and use of the property as single-family that may ultimately make a portion of it infeasible for use as single family. If this is the case, it may become necessary, in the future, to change some of the plan to multiple family. Following is our summary of the recommendations from all of the Advisory Commissions: PRAB The PRAB recommended approval of the project unanimously. The Commission recommended a combination for park dedication of: 5.7 acres of land; park and trail development valued at $172,000; and cash park fee of $44,700. "., Our original proposal was for 4.2 acres of park and trail. The PRAB recommended the deletion of (5) lots, increasing the park area by an additional 1.2 acres. Since that time, we have also learned that the wetland area is actually .6 acres smaller in this area, making the entire area available for park, 6.3 acres. The City Code dictates that when a combination of: land; park development; and cash are required by the City, the total value is subtracted from a total cash park fee applied to the development. Our cash park obligation for 211 homes is $561,260 (211 x $2,660/unit), plus $44,700 for 10 acres commercial, equals: $605,960. Total value of 6.3 acres ofland (at a fair market value of $148,000/ acre, as prescribed by City Code) plus $172,000 in improvements plus $44,700 for commercial equals: $1,149,100. Based upon the PRAB we are exceeding the City Code park requirement by: $543,140. We told the PRAB that we would like to keep the (5) lots, and that if they were taken; it was imperative that we obtain the variances from the City Council to assure the viability of the single-family use. Our ability to shoulder exceeding the City Code in park contribution is dependant upon approval of the project as proposed. If the City Council approves the project without the requested variances, we ask that we be credited for the park contribution in equivalent units: $543,140 - $44,700 (commercial) / $2,660 per unit = 187 units (beyond the 211 unit proposal). EAC The Environmental Advisory Commission unanimously recommended approval of the Preliminary Plat. At the time of approval, the detailed noise analysis was not complete. As of July 11, 2003, URS environmental engineers submitted a noise study indicating: , ''Noise levels do not exceed the City's noise ordinance of70 decibels, and mitigation is not needed. The EAC recommendations exceed the City Ordinance in the following areas: Landscaping and fencing along future Co. Rd. 21 and existing Co. Rd. 18; (6)" of topsoil rather than (4)"; houses constructed using construction materials and methods for indoor noise mitigation. Our proposal exceeds the City Ordinance in the following areas: 74 more trees and 185 caliper inches more than City Code; 2700' natural interpretive trail; management plan for management of the sustainability of the wetland and native plantings proposed in the preliminary plat. Planning Commission The Planning Commission recommended approval of the Preliminary Plat with conditions, and some of the variances (4-2). The initial motion was to approve the plat and variances as proposed, but did not carry (2-4). At the Planning Commission meeting of August 7, (in order to be responsive to the comments of the July 17 Planning Commission meeting, we withdrew the request for a rear yard setback (from 30' required by Code to 20') for the 97 lots lying north of Crossings Blvd. The Planning Commission ultimately recommended approval of 55' wide lots for the 97 lots north of Crossings Blvd. Rather than 50' lots, as we had proposed. The Commission did not recommend approval of the variance requests for side yard or rear yard setback proposed for the 114 lots south of Crossings Blvd. The Planning Commission made it clear that they felt it was not their role to take anything into account for consideration of the variances beyond hardship. There are a number of conditions that the Planning Commission adopted dealing with future Co. Rd. 21. Craig Jensen, Scott County's Transportation Engineer, made it very clear in his letter of July 7,2003, that the County was making no requirements regarding future County Road 21. The 200' of existing ROW borders this project on the north side and this property is not benefited from it by access. The County appreciated that we had largely left structures out of any potential additional future ROW the County might possibly decide they needed. Their comments were to request voluntary cooperation on some items. The City Planning staffhas made recommendations that these requests by the county become requirements of the City. While we will cooperate where we can, delay of construction for some lots in the residential area beyond January, 2004, and any delay in the office area, are not appropriate and should not be made a requirement of this plat. We have revised the Preliminary Plat to conform to the Planning Commission recommendation of increase ROW on Crossings Blvd. and extension of the rear lot lines over storm water ponds. We clearly understand that the City Council balances all of the needs of the City, and the differing recommendations of the advisory commissions. Riverside Fields responds to the following areas we understand are valued by the City of Shakopee: 1. The proposal is for single-family homes in a PRD zoning that would permit up to 640 multiple family homes 2. There are no more homes proposed because of the variances than would be possible without variances. The variances allow important diversity of housing models through out the neighborhood than would be possible without the variances. 3. Shakopee "gets something" if the variances are granted: single-family land-use; 429 less housing units than otherwise allowed under the PRD; park land dedication and development and cash park fee resulting in $498,440 more park value than required by City Code, and; tree plantings and topsoil in excess of the City Code. The Preliminary Plat request is for 211 single-family residential lots with 10 acres of neighborhood commercial and office, permitted under the PRD zoning. We respectfully request that you approve it. The variance requests are for: 1. Lot width from 60' to 50' for the 97 lots north of Crossings Blvd. 2. Side yard setback from 20' combined to 15' combined for all of the lots. For the (97) lots north of Crossings Blvd. It results in more total side yard setback on a street frontage than an equal street frontage for the 55' wide lots the City previously approved for Centex in Southbridge. The variance for the 65' wide lots south of Crossings Blvd. allows (7) models of homes to be built rather than (3), providing for variety in the neighborhood. 3. Rear yard setback variance from 30' to 20' for the lots south of Crossings Blvd. We have withdrawn the request for rear yard setback variance from 30' to 20' for the lots north of Crossings Blvd. We ask that you approve the variances as requested to help assure the viability of this proposal as single-family, and grant approval of the Preliminary Plat for 211 single- family lots and 10 acres of neighborhood commercial and office. Chris Enger Land Resources Manager Ryland Homes Twin Cities R"'"'Crp r-o "\tJtl vl' -- AUG 1 3 2003 CITY OF SHA~{OPEE ~x; . , I . Criterion I The strict enforcement of the ordinance provisions would cause undue hardship because of circumstances unique to the individual property under consideration. Undue hardship means the following: 1.A. The property in question cannot be put to a reasonable use if used under conditions allowed by official controls; The physical elevation of the property creates an undue hardship because of the minimum floor elevation required to meet City Engineering standards requires approximately 500,000 cu. yds. of fill across the entire site. Development of the site given these physical constraints is not feasible with the number of lots resulting from strict adherence to the City's setback and lot width requirements. The recommendation from the Park and Recreation Department and (3) members of the PRAB of a combination of parkland dedication and park development in excess of the City Code further exacerbates the hardship created from the low elevation of the site, by requiring additional fill for the park and resulting in the deletion of (5) additional lots. There is a further area hardship imposed upon the site from a request from Scott County to reserve from structures an additional 100' of potential ROW for future COUlJ.ty Rd. 21, in the event the County chooses to acquire it during 2003. 2.B. The plight of the landowner is due to circumstances unique to the property; The City's Comprehensive Storm water Management Plan and Engineering Standards when applied to the property given its' existing elevation result in an extraordinary amount of fill to make the property developable. This condition is unique to this property and this request. I.C. The circumstances were not created by the landowner. The overall elevation of the property has not been altered. The storm water standards required by the City are higher many communities in the metropolitan area. Adherence to these standard on this property results in an extraordinary amount of fill. I.D. The variance, if granted, will not alter the essential character of the locality; and The lot sizes, width, density, and setbacks are consistent with single-family dimensions and standards previously approved by the City in the South bridge area. Side yard setbacks of 15' and in fact 10 feet as well as lot widths of 50' have been granted in the Southbridge single family subdivisions, and other neighborhoods of the City. I.E. The problems extend beyond economic considerations. Economic considerations do not constitute an undue hardship if reasonable use for the property exists under the ordinance. The City Policy Boards have encouraged the development of single-family subdivisions most recently because of the number of multiple-family developments. The proposed single-family subdivision conforms to the PRD zoning of the site and is a reasonable use of the property; perhaps a City preferred reasonable use of the site. Because of the physical constraints of the site, the setback and lot width variances are necessary to provide a physical design that supports the extraordinary amount of fill required to develop the site. If it weren't for the fill requirement, the plat could be designed without variances. Criterion 2 It has been demonstrated that a variance request will be in keeping with the spirit and intent of this Chapter. The City has approved lot size and setbacks the same or greater in the immediate area. The plat meets all other City requirements. The request: I)Exceeds the park requirement. 2)Exceeds the City's tree replacement requirement in both number an size of tree. 3)Meets or exceeds the City's engineering standards for storm water management. 4)Conforms with the City's noise standards for properties adjacent to major roads. 5)Provides an transportation connection not required in the City Transportation Plan. 6)Responds to the City's desire for more single-family development. 7)Exceeds the City's ordinance for depth of black dirt for good stewardship of a water resources. 8)Provides a environmental interpretive trail not required by City ordinance. Criterion 3 The request is not a use variance. The request is not for use. Criterion 4 Conditions assured by the Board of Adjustment and Appeals will insure compliance to protect the adjacent properties. The Preliminary Plat is in conformance with all aspects of the City Code with the exception of the variances requested. The variances can be enforced in the same way as the underlying requirements of the Code. In the areas, such as Park, and Enviromental, where the Boards have made recommendations that go beyond those standards required by City ordinance, the City could make them requirements by making them conditions of approval of the variances. Criterion 5 Variances in the floodplain The site is not within a Floodplain Zone. N.A. . RIVERSIDE FIELDS ENVIRONMENTAL ENHANCEMENT . Preservation of existing wetlands . Protection of existing wetlands . Enhancement of wetlands . Environmental trail . Lower density . Less impervious coverage . Less storm water runoff .

This application was continued by the Commission at their July 17, 2003 meeting, although there was substantial discussion regarding street and lot size/setback issues. Basic site and development information is as follows: Site Size: 79.82 acres Total RO.W.: 13.92 acres Total Lot Area: 49.82 Total Outlot Area: 16.08 Proposed No. of Lots: 213 Proposed No. of Out lots: 2 Proposed Density: Gross (excludes outlots, Lot 34, Blk. 2 and Lot 65, Blk. 1):3.9 dwelling units/acre Net (excludes above plus ROW): 5.2 dwelling units/acre Range of Res . Lot Sizes: 5,640 sq. ft./ - 16,344 sq. ft. Average Lot Size: 8,307 sq. ft. CONSIDERATIONS: The applicant is proposing a mixed-use development that would consist of single-family residential lots (66 acres), office use and neighborhood commercial (10 acres), and wetlands (3.5 acres). Additionally, as part ofthe application, the applicant is requesting approval of variances to the lot width requirement (50 feet minimum, where 60 feet minimum is required), and 15 feet side yard setbacks between structures, where 20 feet minimum is required. The original application had included a variance request for 20-foot rear yard setbacks, where 30 feet is the minimum rear yard setback requirement. The rear yard setback variance request has been withdrawn by the applicant, and they will work with potential builder(s) to design structures that comply with the rear yard setback requirements. Section 11.89, Subd. 2, of the City Code contains provisions for the granting of variances only if all ofthe following criteria are met. The applicant has provided a rationale for the requested variances as they relate to site conditions (Exhibit C). The question for the Commission is whether the site conditions themselves justify the request, or whether they go to the economics of developing the site. Staffhas provided the required criteria for the commission's information. The Planning Commission should provide direction to staff as to whether it believes the criteria are met. Criterion I The strict enforcement of the ordinance provisions would cause undue hardship because of circumstances unique to the individual property under consideration. Undue hardship means the following: 1.A. The property in question cannot be put to a reasonable use if used under conditions allowed by the official controls; 1.B. The plight of the landowner is due to circumstances unique to the property; 1.c. The circumstances were not created by the landowner; 1.D. The variance, if granted, will not alter the essential character of the locality; and 1.E. The problems extend beyond economic considerations. Economic considerations do not constitute an undue hardship if reasonable use for the property exists under the terms ofthe ordinance. Criterion 2 It has been demonstrated that a variance as requested will be in keeping with the spirit and intent of this Chapter. Criterion 3 The request is not for a use variance. Criterion 4 Conditions to be imposed by the Board of Adjustment and Appeals will insure compliance to protect the adjacent properties. Criterion 5 Variances in the flood plain overlay zone also shall meet the following criteria.... (This criterion is not an issue in this particular application). Because CSAH 18 and future CSAH 21 isolate the site, the provision of park and recreation opportunities is important to the site as well, and this concern has been addressed by the Parks and Recreation Advisory Board (PRAB), as noted in the memorandum from Mark McQuillan and Mark Themig (Exhibit D). PRAB reviewed the proposed preliminary plat application at their July 28, 2003 meeting and recommended approval with the following conditions: 1. The applicant shall dedicate approximately 4.2 acres of parkland to satisfy the need for a park to serve this area, and a 20-foot trail area for a total of approximately 5.7 acres. 2. The applicant shall construct and install an 8 foot wide asphalt trail along the Yz mile levee trail, a trail/sidewalk along the north side of "Commercial Street", and other trail/sidewalk areas as shown on the preliminary plat. 3. The applicant shall make additional improvements to the park area, including 6 inches of topsoil, grading, turf establishment, playground equipment, picnic areas/shelter, and open space for field games, which would satisfy and possibly exceed the park dedication requirements. 4. The developer should work with staff and bring back development options of the park to the Parks and Recreation Advisory Board for review prior to recording of the final plat. Condition number 1 states there would be a total of approximately 5.7 acres of parkland dedication. This figure includes the removal of the five lots adjacent to Street 5 (Lots 1& 2, Block 6, and Lots 83 through 85, Block 3, located in the southwest corner of the proposed development). Additionally, the applicant stated that a new wetland delineation study has been completed recently. This study reported that the wetland area is approximately .6 acres less than what was previously known, and that this .6 acres ofland will be included as parkland, which would bring the total to 6.3 acres of parkland to be dedicated as part of this project. The EAC reviewed the proposed preliminary plat application at their July 9,2003 meeting and recommended approval with the following conditions: 1. The applicant shall implement the use of Best Management Practices for erosion control and stormwater management during construction. 2. The applicant should transplant healthy young trees on site whenever possible. 3. The developer shall install rain sensors for the irrigation system. 4. The homeowner's association shall develop a management plan for the sustainabilityof the wetlands and native plantings proposed in the preliminary plat. 5. The applicant shall include 6 inches of topsoil on the entire site. 6. That all sprinklers owned and operated by the Homeowner's Association have rain sensors as required by State Law. 7. The applicant shall construct houses using construction materials and methods for indoor noise mitigation. 8. The applicant shall incorporate a benn and/or a 6 foot fence with a variety of trees along CSAH 21 and CSAH 18, or wherever appropriate, to mitigate noise from the highways. Other Review Comments Received: The Engineering Department had submitted a memorandum (Exhibit E), providing a number of conditions that staffhave incorporated into the draft resolution. One of the issues that had staff recommending a continuation of the application at the last meeting pertained to the need for a traffic study of Street #1 (east/west street running the entire length of the property). There has been substantial discussion between the developer and City staff regarding the issues and details pertaining to project future traffic volumes and determine the roadway classification, right-of- way width (for example, Street #1 will be designed with a 66 foot right-of-way, with 5 foot sidewalks on both sides of the street and 9 foot boulevards) and intersection spacing requirements. However, as ofthe time ofthe preparation of this report, staff has not received revised plat drawings that show the design changes that had been requested by City staff. Therefore, City staff is recommending a continuation of the application until the revised plat drawings have been submitted. Scott County Public Works Department has provided a letter (Exhibit F), which addresses several issues. Specifically, the County has provided extensive discussion on the proposed CSAH 21, and the potential need for additional right-of-way. They noted their position on this issue, and provided several options that the Commission should consider in their recommendation to Council. Shakopee Public Utilities Commission submitted comments (Exhibit G), noting that a 16" trunk watermain along CSAH 18 and a 12" trunk watermain in proposed Street #1 will be required within this development. Planning staffhave sent a letter to the Minnesota Planning Environmental Quality Board, asking that they provide a response setting forth their position on whether an amendment of the Shakopee Crossings Alternative Urban Areawide Review (AUAR) would be required. It is staff s determination that an amendment is not necessary as the proposed development would have less of an impact than that proposed in the original study. ALTERNATIVES: 1.

Road 21. The total site is eighty acres in size. The proposal includes an office use, two different types of commercial and t"~iO different types of single-family residential. The neighborhood office is 25,000 square feet designed in a residential theme. The commercial is made up of 10,000 square feet or neighborhood shopping, and a convenience commercial store, together with the . office on ten acres. In addition to the 1 0 acres of office .and commercial use, the proposal includes: 47 acres of medium-size single family residential; 19 acres of smaller lot single family; 4 acres of city parkland; 3 Y2 acres of wetland; a private park with a neighborhood pool; and over 12 mile of recreation trail in addition to neighborhood sidewalks. Existing and Proposed Use This mixed-use neighborhood is proposed on property cUlTently zoned Planned Residential Deydopment (PRD). The uses are all allowed in that zoning district. The City had also previously 'Submitted the site to the Metropolitan Council as a mixed-use site for d Liveable Communities grant. Rylr,nd Homes is se:1sitive to the growing concern by the City over multiple-family in Shakopee, (especially in this area). We are pleased to propose a single-family mixed-use development at 3 homes per acre gross density. The two, single family neighborhoods are pr0posed at significantly lower density than allowed by the Comprehensive Plan or the Zoning ordinance and are detached rather than multiple-family. The number of multiple family units allovyed under the PRD zone on this 80 acres would be almost 500, or up to 8 units per acre. There are 211 single-family homes proposed. Road network The plan conforms to the transportation plan of the City. A centro.l neighborhood through road is planned east/west through the site. There is a single access point at Co. Road IS, E '('\o-ll e IT c.. ~/e-. consistent with County plans, and there is no access requested from future Co. Rd. 21. There is 200 feet of existing ROW for Co. Road 21 adjacent to the northern boundary of the site. If the County were to determine they need any additional ROW, they must contract for the purchase of it at this time. The road network is planned to: limit access to County Road 18, as required; provide for a continuous through road; and make use of loop streets where ever possible from a drainage standpoint to confonn with City Policy. There are no lots fronting onto the central street. All street widths and ROW's are designed to City standard. Traffic generated from the residential portion of this property will be significantly less than with over twice as many units of multiple-family. The neighborhood and office uses will be mostly captured trips going-to- work or corning-home traffic. The neighborhood shopping and office will be off-peak. hour. The mix of land uses 'will help provide a balance of traffic. Noise Mitigation The homes will be constructed of materials and in a fashion to meet the indoor noise standards for Co. Rd. 18. Although Co. Rd. 21 is not in place at this time and the County would be obligated to provide appropriate noise mitigation in the fuhlre, the homes will be built to mitigate noise to indoor standards. Because of the requirement for a large amount on on-site ponding, berming is not possible. A six-foot high fence and evergreen trees will be placed along both County Road 18 and future County Road 21 to further mitigate noise. Noise studies for ~ounty Road 18 and a County Road 21 have been provided. Engineering The site is relatively flat, made up of sandy soils, but, has fairly high ground water. Relative to the City Storm water plan, the site is low and requires a substantial amount of import in order to met the standards for minimum floor elevation. Not only does tIus make development very expensive, but also, it requires a large portion of the site to be devoted to storm water ponds and the entire site to be filled 4-8. Because of: the large amount of fill necessary to raise the site to meet City engineering elevation standards; the requirement for a large area of the site to be devoted to storm water ponds; and the recommendation for 4 acres of parkland; lots must be sized to malce efficient use of the remaining developable land in order to make single-family development of the land practical. Requested Waivers In order to reduce the density from that allowed in tbis zoning district (up to 8units/acre) to single family (3units/acre gross), we need waivers to some setbacks and lot widths. We are requesting a waiver to allow 15' between houses rather than 20'and a 50' minimum '~i'fott~\~ 'L 3!f-, lot width rather than 60'on 97 of the lots (or a 60' average lot width rather than minimum on 211 lots). We are also requesting a minimum 20' year yard setback rather than 30'. We are using single-family floor-plans that can be accommodated on a 65 foot and 50 foot wide lots. Both collections ofhomes work well with a combined distance between houses of 15 feet. There are 114, 65-foot wide lots, accommodating a three-car garage. The 97 homes designed for the 50-foot wide lots would have two-car garages. Hardship and mitigation . The site is naturally constrained because it is low in relationship to the City's planned storm-water system. In order to build, the site must be raised between four and eight feet. This makes efficient use of the site important in order to make the site developable practically. . The large amount of frontage on future County Road 21 and existing County Road 18, make the marketing oflarge single-family lots infeasible. . The natural and engineered constraints of the site require an extraordinary amount offill and a high percentage of the site for storm-water holding ponds. . Almost 1/3 of the site is devoted to wetlands, storm-water ponds, trails, or parle. . The 5' waiver on side-yard setback has precedent in other parts of the City. . The average lot width is in excess of 60' . . The 15' distance between houses would be a minimum, in some cases a buyer would chose a smaller floor plan or a two car garage, that would result in meeting the 20' setback. ; The City Staff recommends four acres of the property for dedication. If all lots met the side-yard set back requirement, it would eliminate the land dedication possible for park. The reduction in side-yard set-back by five feet and minimum width equate to four acres of land, that is better used as City Park land, and open game fields. . Because of the more than twelve acres of storm water area required, for every acre reduction in stOl1n water pond one acre of park could be dedicated. . The four acres of City park land made possible by the reduction in side-yards can be aggregated with other planned dedications currently being discussed with the City, to help meet the City's Comprehensive Plan goals for park in the neighborhood. Park (Trails ( Park Development The City staff has suggested that it is appropriate to provide a combination of: cash park fee, parkland, and parkland development for this neighborhood. The cash park fee for 211 homes would currently be $2,660/home and $4,470/ acre for commercial and office area. Shakopee's ordinance provides when a combination of land, cash, and development is required by the City, that the fair market value of land that the City wants for park dedication plus the actual cost of park development be subtracted from the cash park fee. In addition, the City my give credit for any private recreational amenity. Ryland is planning to build a neighborhood pool for this development. ~V~t8 ,.,...C ~/<<- In this case, the fair market value (as defined by City ordinance) of the four acres of parkland to be dedicated exceeds the cash park fee and trail and park development. Any cash park fee, plus additional public and private park development become an additional mitigation supportive of reduced setback and lot width requirements. Natural Features There is a three and one-half acre wetlalld at the southwestern boundary of the site. This will be preserved in its' entirety and protected with storm-water ponds. We are proposing a trail for dedication to the City along it the northern border ofthe wetland. A wetland report has been compiled and the wetland has been previously identified and approved by the City. We have done a tree inventory of the northwestern and northeastern treed areas ofthe site. The areas are shown on the City's Natural Resources Inventory as Type 2 and Type 3 woods of lower quality and condition. Because of the engineering requirements for the site, it must be raised 4-8' and the trees will be removed. The Landscape plan far exceeds the replacement required by the City. Landscape Plan The Landscape Plall provides a tree on each single-family lot, in excess of the ordinance requirement. In addition, evergreen landscape and fencing buffers are planned along the County Roads. The number of trees required for tree mitigation exceeds the City ordinance. Summary Ryland Homes is pleased to propose a Preliminary Plat for a single-family, mixed-use development on this site. We have worked with the City staff to develop a plall that meets the City's goals in a way that also makes the development of single-family feasible on a site designated for higher density. We are able to offer a Public/Private parle and trail package that becomes a part of a larger planned City system, to provide needed recreational amenities for the residents of this new neighborhood. r-~ respect~lly request your positive consideration of Riverside Fields. l!J~ I LJ ", ' Chris Enger 0 Land Resources Manager Ryland Homes, Twin Cities Division e,,\-t \&fr c.. &SI" NOISE RESPONSE The proposed Riverside Grove-Shakopee Crossings Development has the potential to generate noise fi-om two types of sources: . Construction activities; . Additional traffic generated by the development. Significant noise impacts occur when: 0 Noise levels increase by ~ 3 decibels (dBA); . Noise levels exceed state staJ.1.dards. There are two descriptors for state noise standards: . L 1 0 - the 90th percentile in which noise levels are exceeded 10 percent of the time. . L50 - the 50th percentile in which noise levels are exceeded 50 percent of the time. Minnesota noise standards are listed by time of day and land use in the attached table. Noise impacts fi'om construction of the development may exceed the state noise standards for a limited period of time. Every effort will be made to reduce construction noise by ensuring that all equipment has proper noise reduction devices. Noise impacts from post-project traffic volumes were evaluated using the STAMINA 2.0 (FHWA 1982) model provided by Jv1NDOT. STAMINA 2.0 predicts A-weighted noise levels (LEQ, LI0, L50 and L90) based on traffic VOh1l11e, speed, and vehicle type. For tIns analysis, velncles were placed into three categories: cars, medium trucks, and heavy trucks. The principal source of additional noise may be future traffic generated along the roadways surrounding the proposed development, mainly CSAH 18 and proposed Road D. The nearest residences are located approximately 60 feet north of CSAH 18 along the southem edge of the proposed development. Other potentially noise sensitive areas include any nearby schools, churches or parks, hotels, as well as outdoor restaurants. Only daytime (rush hour) impacts were predicted using 8T AMJNA 2.0. Nighttime noise standards only differ from daytime noise standards in residential areas. Peak nighttime traffic is assumed to be 78 percent of the peak daytime volume using :tv1::l\!l)OT methods. E.~\-l\~n- ~ C,lv The following vehicle type percentages were used: . Cars: 96 percent; " Medium trucks: 3 percent; . Heavy trucks: 1 percent. Traffic volumes provided by Benshoof & Associates, Inc. were used for the STAMINA 2.0 model runs. The worst-case condition traffic, PM peak-hour traffic, was used for this modeling. The attached table (Stamina Noise Modeling Results) slUnmarizes the STAlv1INA 2.0 model results for 2006 and 2020 Build Conditions at the Riverside Grove-Shakopee Crossings Development. The 'No Barrier' Scenario does not consider a reduction in noise propagation via trees, benTIS, walls, etc. and is included as a baseline model only. The existing tree line along CSAR 18, which will remain under the build condition, will serve as a noise balTier and is modeled tmder the 'Tree Barrier' Scenario. Results surrunarized in the table indicate that modeled noise levels lUlder the Barlier Scenario slightly exceed state standards at one receptor, R-2, under both 2006 and 2020 build conditions. R-2 is located approximately 50 feet nOliheast ofCSAR 18 near the back lot line of the proposed residential area. The LI0 standard was exceeded by 2.5 and 0.1 decibels for the 2006 and 2020 build conditions, respectively, and the L50 standard was exceeded by 0.7 decibels for the 2006 build condition. It should be noted that completion of alternate traffic routes, namely CSAH 21, will reduce traffic voltmles on CSAH 18 between 2006 and 2020. Although state noise standards are slightly exceeded near the southem edge ofthe proposed residential area, noise levels within residential buildings should have no detrimental effects to human health and wiUnot require special construction materials or procedures. Open windows and doors may increase noise levels in celtain residences near CSAR 18. To mitigate tbis possibility, a row of trees or bushes, 5 to 10 feet tall, with ground to crown cover may be planted along C8AR 18 or the back lot line of the residential development nearest C8AR 18. Additional mitigation measures to further decrease noise levels in the vicinity of the development include: II Reduction of the speed limit along noise-sensitive sections oflocal roadways; . Installation of a additional noise barriers (e,g., walls, berms, trees); . Combination of reduced speeds and barTier installation. !'\e4-t, ~ rr 0 'It. CITY OF SHAKOPEE MEMORANDUM To: Shakopee Planning Commission Michael Leek, Community Development Director From: Mark J. McQuillan, Natural Resources Director Mark Themig, Facilities and Recreation Director Subject: Preliminary Plat Review of the Riverside Fields and Variance for side & rear setbacks and lot width Date: July 29, 2003 INTRODUCTIONI BACKGROUND Chris Enger of Ryland Group, Inc. has appeared before the Park and Recreation Advisory Board (PRAB) and the Environmental Advisory Committee and presented a Preliminary Plat for Riverside Fields. Riverside Fields is an eighty-acre parcel located west of CRi8 and in the southeast corner of future County Road 21. The site is guided and zoned for Planned Residential Development. The Applicant is requesting a PRD and proposes an office use and commercial use on 10 acres, medium- size single family residential on 47 acres, smaller lot single family on 19 acres, four (4) acres of city parkland, a private park with a private pool and about a Y2 mile of recreation trail in addition to neighborhood sidewalks. On the southwestern area of the site is three and one-half acres of wetland that the applicant intends to preserve. The Applicant proposes to construct and elevated trail (levee) and storm- water ponds north and adjacent to the wetlands. The Applicant has offered to include environmental interpretive signs along the trail by the wetlands with staff's cooperation. The applicant has submitted a tree inventory and tree replacement plan for their development. The woodland areas are shown on the City's NRI as Medium and Low Quality woods. Removal of trees will occur because the site must be raised anywhere from 4' to 8'. Ryland is removing a total of 306 trees. Normal landscaping requirements of one tree per lot equates to 211 trees (lots) at 2.5 inches or 527 caliper inches. Replacement caliper inches 306 trees at 1.5' minimum equates to 459 caliper inches. The total tree replacement schedule indicates the developer would need to plat a total of 986.5 caliper inches. Ryland's plan proposes to plant 1,171.5 caliper inches, which exceeds the City's requirements. This site was included in the Shakopee Crossings September 2000 AUAR. The City's Comprehensive park Plan identifies a need for an eight acre park in this area. Staff has held numerous discussions with Applicant to look at a variety of options. Those options included the following: 1. That park dedication requirement be met through land dedication. a. This option would ensure a large 8-acre park for the area, but may impact the type of development being proposed. It could be, at least, 3-5 years before it can be developed. 2. That park dedication requirement be met through a cash contribution in lieu of parkland, and be paid at time of recording the final plat. a. This option would provide additional cash for the development of future parks, but it could leave a deficiency of parkland in this area as identified in the Park Compo Plan. "E ~~ \ e .,- 0 ~/7- 3. That park dedication requirement be met through a combination of land and cash dedication. a. This option has been proposed by the Applicant, with possible improvements made to the park by the developer. 4. Deny approval of the plat as presented. PRAB RECOMMENDATION The PRAB was a member short of having a qorum when this plat went before them on June 23, 2003. However, from the discussion the Applicant had with the three members that evening, the general consensus of the members present were as follows: 1. The Applicant shall dedicate approximately 4.2 acres of parkland to satisfy the need for a park to serve this area, and a 20' trail area for a total of approximately 5.7 acres. 2. The Applicant shall construct and install an 8-foot wide asphalt trail along the % mile levee trail, a trail/sidewalk along the north side of "Commercial Streee', and other trails/sidewalk areas as shown in the Preliminary Plat. 3. The Applicant shall make additional improvements to the park area including adding adequate fill to ensure the park does not experience high water issues, 6 inches of topsoil, grading, turf establishment, playground equipment, picnic areas/shelter, and open space for field games, which would satisfy and possibly exceed the park dedication requirements. 4. The developer should work with staff and bring back development options of the park to the Parks and Recreation Advisory Board for review prior to recording of the final plat. EAC RECOMMENDATION The EAC recommended approval of the Preliminary Plat with the following conditions: 1. The Applicant shall implement the use of Best Management Practices for erosion control and stormwater management during construction. 2. The Applicant should transplant healthy young trees on site whenever possible. 3. The developer shall install rain sensors for the irrigation system. 4. The homeowners association shall develop a management plan for the sustainability of the wetlands and native plantings proposed in the preliminary plat. 5. The Applicant shall include 6 inches of topsoil on the entire site. 6. That all sprinklers owned and operated by the Homeowners Association have rain sensors as require by State Law. 7. The Applicant shall construct houses using construction materials and methods for indoor noise mitigation. 8. The Applicant shall incorporate a berm and/or six-foot fence with a variety of trees along CR21 and CR18, or wherever appropriate, to mitigate noise from the highways. E 1C tot \~ \T"" E..

VERMILLION PUBLIC WORKS DIRECTOR BRADLEY J. lARSON COUNTY HIGHW A Y ENGINEER July 7,2003 Mark Noble City of Shakopee 129 South Holmes Street Shakopee, MN 55379 RE: Preliminary Plat, Riverside Meadow West of CSAH 18 and South of Future CSAH 21 Dear Mark: The COtmty is working on an Environmental Impact Statement (EIS) for future CSAH 21. There is an existing 200 foot corridor for future CSAH 21 abutting the north side of this plat. The scoping document has indicated the potential for a 300 foot corridor for CSAH 21. This development proposal could limit the options the County has to develop a road alignment for future CSAH 21 or intersection/interchange design for CSAH 21/CSAH 18/Southbridge Parkway. If the City chooses go forward with the development without changes to the plat, we offer the following comments. . At this time, the County is not in a position to determine whether an additional 100 feet of right-of-way is needed. The developer has been made aware of the potential need for additional right-of-way. The County appreciates that the developer has left proposed structures and most residential lots out of the possible 100 feet of additional right-of-way. However, if a 300 foot corridor is needed it would impact the rear yard of some proposed homes. We request at this time, that at a minimum, a 50 foot drainage/utility and trail easement be placed on aU property adjacent to future CSAH 21. We also request that the lots that could be impacted by the potential 100 feet of additional right-of-way be reserved for the last phase of the development, and that these lots are not sold until some the preliminary design issues regarding future CSAH 21 have been resolved. We anticipate a preliminary design for future CSAH 21 to be drafted over this winter. If the lots that could be impacted were reserved, the County/City would have the opportunity to acquire the lots if it is determined that the lots would be. needed for the construction of CSAH 21 in the future. . The landscaping plan shows proposed plantings and fence to be adjacent to the County right-of-way for future CSAH 21. We recommend that these plantings and fence be moved to rear yards of the individual residential lots. This would allow for the landscaping and fencing to be mostly outside the additional 100 feet ofright-of- way that could be needed in the future. Even if additional permanent right-of-way would not be needed, any landscaping in the area they are proposing to place it may have to be removed to properly grade CSAH 21. + Noise issues may arise as traffic levels increase on CSAH 18 and once CSAH 21 is open to traffic. The application material incorrectly states that noise mitigation is the responsibility of the County. As per 7030 of Minnesota Rules, noise attenuation is the responsibility of the land use authority. + The noise report that was submitted with the packet does not address future CSAH 21 or indicate the name/company that prepared the noise report. ~\(+t\~\-r f' ?, I,.. Riverside Meadows Page 2 No landscaping, ponding, benning, or signage shall be permitted within the County right-of-way. . .. .. Any change in drainage entering the County right-of-way shall require detailed stormwater calculations to be submitted to the County engineer for review and approval. .. We request a street light to be installed at the intersection of CSAH 18 and the proposed collector street. .. A County access permit shall be required for Street 1 at CSAH 18. A right and left turn lane on CSAH 18 shall be required. No other accesses or direct access shall be granted to the development. .. Any work within the County right-of-way shall require a pernlit.
