The applicant will work with staff to incorporate a tot lot or similar playground facility within this development which will help preserve trees. 9. Provide an access trail from this neighborhood to Minnetonka Middle School West at the west end of street A. Staff concurs with the majority of the Planning Commission changes with the exception of conditions 5.o., 5. q., 5. r., and 8. For condition 5. o., staff believes that Street B shall be connected to Crestview Drive and the condition should remain as originally proposed by staff. "A temporary cul-de-sac turnaround for emergency vehicles will be required at the north end of Street B along with a sign stating that the road will be extended in the future." The City's Comprehensive Plan states: "It is the city's policy to require interconnections between neighborhoods to foster a sense of community, to improve safety, and to provide convenient access for residents." The Planning Commission at their public hearing on January 4, 2005 in review of the Crestview development being proposed north of this development reiterated that the street connection should not be made between the two neighborhoods. Instead, a trail connection should be incorporated in the approximate location of the two streets. For condition 5. q., staff met with the applicant's Engineer on January 4, 2005, to review the proposed sewer alignment. It remains staff's recommendation that the sewer shall be routed to Manchester Drive, rather then across the western end of the parcel. Mr. Todd Gerhardt • Pinehurst Rezoning and Subdivision with Variances Planning Case No. 04-36 January 10, 2005 Page 3 The applicant is proposing a second gravity sewer line to serve the western two-thirds of the site. This sewer line, which runs from MH -18 to an existing manhole in Lake Lucy Road, is proposed to go south outside of the pavement and right-of-way, through Lot 17, Block 1 and cross over City -owned property prior to connecting to the existing sewer line in Lake Lucy Road. Staff is recommending that this western sewer line be eliminated for the following reasons. First, the City -owned land that the sewer would run through is very steep. City staff has concerns with access and maintenance of such a line on a steep slope. Short- and long-term restoration of the steep, 3:1 slope could become problematic in the future. Second, the City -owned property was originally acquired as a possible future well site. The location of the sewer line on the property will limit the possible well locations. Third, the proposed sewer line itself will have a steep slope on the pipe. This can, in turn, create maintenance issues in the downstream manhole. The high velocities of the sanitary waste flows can lead to a premature deterioration of the interior of the concrete manhole. Finally, the existing sanitary line in Manchester Drive was stubbed to this property and was always intended to serve the entire site. For condition 5. r., staff proposes that the developer provide a standard cul-de sac in conformance with the city's standard for public cul-de-sacs, rather than 28 feet wide "eyebrow" The Parks Director recommended that only park fees be collected from this development since the development is within the service area for Pheasant Hills Park, has access to Minnetonka Middle School West athletic facilities and Minnewashta Regional Park. Staff recommends that proposed condition 8. be deleted. UPDATE As part of a court judgement approved on October 17, 2000, the following described property was added to Lot 1, Block 1, Old Slocum Tree Farm: That part of the following described property: That part of the Southeast Quarter of the Northwest Quarter of Section 3, Township 116, Range 23 West described as follows: Commencing at a point on the South line thereof distant 1056.5 feet East of the Southwest comer thereof; thence East along the South line thereof 231.5 feet; thence North 2 degrees 55 minutes West a distance of 86.66 feet; thence South 87 degrees 15 minutes West a distance of 138 feet; thence South a distance of 204.7 feet to the point of beginning. Which lies south of a line and its extensions drawn from a point on the East line of the above described property a distance of 6.8 feet North of the Southeast comer of the above described property to a point on the West line of the above described property a distance of 8.2 feet North of the Southwest comer of the above described property. Mr. Todd Gerhardt • • Pinehurst Rezoning and Subdivision with Variances Planning Case No. 04-36 January 10, 2005 Page 4 That part of the following described property: That part of the Southeast Quarter of the Northwest Quarter of Section 3, Township 116, Range 23, Carver County, Minnesota described as follows: Commencing at the southwest corner of said Northwest quarter, on an assumed bearing of south 87 degrees 12 minutes 20 seconds east, a distance of 2,126.74 feet to the point of beginning of the parcel to be described; thence easterly on an extension of the last described line a distance of 261.22 feet; thence north 02 degrees 47 minutes 40 seconds east a distance of 204.82 feet to a point thereafter called Point A; thence North 83 degrees 40 minutes 20 seconds west a distance of 197.60 feet to a point hereafter called Point B; thence South 02 degrees 47 minutes 40 seconds west a distance of 40 feet; thence south 40 degrees 08 minutes 28 seconds west a distance of 105.50 feet; thence south 02 degrees 47 minutes 40 seconds west a distance of 93.13 feet to the point of beginning and there terminating. Which lies south of a line and its extension drawn from a point on the east line of the above described property a distance of 8.2 feet north of the southeast corner of the above described property to a point on the west line of the above described property a distance of 7.2 feet north of the southwest corner of the above described property. In order to avoid having a sliver of property which was legally created being separate from the abutting lands, these lands shall be included within the area of the Pinehurst subdivision and be apportioned to the appropriate lots within the development. This will increase the area of some of the lots in Block 2. The applicant disputes condition 5. p. and believes that they can mitigate potential drainage issues. City staff still has concerns regarding runoff volumes and rates from Lots 23-26, Block 1 onto Lot 27, Block 1. The primary concern relates to the expectations of the future owners of Lot 27. Staff has received complaints in many instances where swales are intended to convey runoff through rear or side yards. Issues arise when either the swale is improperly graded by the developer, builder, landscaper or homeowner and impounds water or when property owners do not expect water to pool or flow intermittently in the swales. The lowest portions of swales tend to hold water. This can make it difficult for property owners to mow those areas. Because they expect to have a lawn that can be mowed without causing tire ruts, property owners can become frustrated and contact staff. In addition, the movement of water through residential areas can result in erosion or difficulty in establishing vegetation. According to Section 18-39 of the Chanhassen City Code: "(f) The findings necessary for city council approval of the preliminary plat and the final plat shall be as follows: (4) The proposed subdivision makes adequate provision for water supply, storm drainage, sewage disposal, streets, erosion control and all other improvements required by this chapter." Mr. Todd Gerhardt • • Pinehurst Rezoning and Subdivision with Variances Planning Case No. 04-36 January 10, 2005 Page 5 The subdivision as proposed does not make adequate provision for storm drainage on Lot 27. Due to these outstanding concerns, the recommendation of City staff continues to be to eliminate Lot 27. However, in the event that Lot 27 is approved, i.e., condition 5. p. is deleted, staff recommends the addition of the following two conditions: 1. A drainage and utility easement shall be dedicated over the entire width of the swale on the northwest side of the buildable area on Lot 27, Block 1. No structures shall be allowed within this drainage and utility easement, with the exception of the retaining wall shown on the approved grading plan. 2. To ensure proper drainage, a survey shall be required for Lot 27, Block 1 upon completion of the landscaping. The survey shall be submitted to the City and reviewed by staff to ensure consistency between final grades and the approved grading plan. If discrepancies exist, any inconsistent areas shall be re -graded to match the approved grading plan. Additionally, any property owners should anticipate flowing and/or standing water within the swale on the northwest side of the property (Lot 27, Block 1). This may preclude mowing of the swale during times of above average precipitation." RECOMMENDATION Staff recommends adoption of the motion beginning on page 9 as specified in the staff report dated December 7, 2004 as modified by the Planning Commission with the following modifications to those conditions: 5.

LOCATION: 6620 & 6640 Galpin Boulevard Lots 1 & 2, Old Slocum Tree Farm APPLICANT: Plowshares Development, LLC 1851 Lake Drive West, Suite 550 Chanhassen, MN 55317 (952) 361-0832 PRESENT ZONING: Rural Residential (RR) 2020 LAND USE PLAN: Residential — Low Density (Net Density Range 1.2 — 4.0 units per acre) ACREAGE: 27.62 DENSITY: 1.52 units/acre gross; 1.85 units/acre net SUMMARY OF REQUEST: The applicant is requesting a rezoning from Rural Residential to Single - Family Residential to permit a 43 -lot subdivision. As part of the subdivision request, the applicant is requesting variances for private streets. LEVEL OF CITY DISCRETION IN DECISION-MAKING: The City has a relatively high level of discretion in approving rezonings because the City is acting in its legislative or policy making capacity. A rezoning must be consistent with the City's Comprehensive Plan. The City's discretion in approving or denying a preliminary plat is limited to whether or not the proposed plat meets the standards outlined in the Subdivision Regulations and Zoning Ordinance. If it meets these standards, the City must approve the preliminary plat. This is a quasi-judicial decision. The City's discretion in approving or denying a variance is limited to whether or not the proposed project meets the standards in the Subdivision Regulations for a variance. The City has a relatively high level of discretion with a variance because the applicant is seeking a deviation from established standards. This is a quasi-judicial decision. 0 Location Map Pinehurst 0 City of Chanhassen Planning Case No. 04-36 Subject Site Pinehurst Rezoning & Subdivision with Variances Planning Case No. 04-36 December 7, 2004 Page 2 PROPOSALISUNDURY The developer is proposing a 43 -lot single-family residential subdivision. As part of the subdivision, the applicant is requesting the use of two private streets at the western end of the development. These private streets permit the developer to preserve significant areas of woodland. The use of the private street meets the requirements of the subdivision ordinance for approving private streets. The developer had previously submitted a subdivision proposal that included variances from the city's street standards as well as front yard setback variances. However, staff worked with the developer to get a plan that complied with city code requirements and provided lot sizes that accommodate most of the housing plans being proposed. In meeting city requirements, additional tree removal occurs. The plan being reviewed complies with the zoning ordinance requirements. The property is currently zoned Rural Residential, but is guided by the comprehensive plan for Residential — Low Density development. The proposed rezoning of the property to Single Family Residential District, RSF, is consistent with the land use designation and is the same zoning as the surrounding residential developments. The site is located north of the Woodridge Heights development, a 46 -unit single-family development (net density 1.67 units per acre), and east of Brenden Pond, a 21 -unit single family development (net density 1.68 units per acre). To the north are Minnetonka West Junior High and an older neighborhood. The north - south street is being extended to the northerly property and will be extended with the development of the Shively Addition, which has the potential for subdivision into five lots, providing a connection to Crestwood Drive. Water and sewer service were extended to the southerly property line with the development of Woodridge Heights. This proposed development will extend water and sewer service to the northerly property line as well as looping the water back to Galpin Boulevard. A trail is located on the west side of Galpin Boulevard. Sidewalks will be included on all the public streets within the development. The site's high point with an elevation of 1070 is located in the north -central portion of the property. From there, it falls east to an elevation of 1034, south to an elevation of 1020 and west to an elevation of 1020. There is a drainage ravine and wetlands located in the western portion of the site. The site consists of significant areas of woodlands located primarily on the western portion of the property. Rows of pines nun north -south delineating the western 530 feet of the property and along the northern and eastern property lines. Other areas of trees are scattered over the easterly 1300 feet of the property. Staff is recommending approval of the development subject to the conditions of approval. BACKGROUND The easterly 13.5 acres of the property was subdivided into two lots as part of the Old Slocum Tree Farm Addition on April 6, 1987, with lot areas of 4 and 9.5 acres. The rear 14.12 acres were required to be attached to Lot 2, Block 1, Old Slocum Tree Farm as a condition of the plat approval. At that time, the property was zoned Rla, Agricultural residence. Pinehurst Rezoning & Subdivision with Variances Planning Case No. 04-36 December 7, 2004 Page 3 REZONING The applicant is proposing the rezoning of the property from Rural Residential, RR, to Single -Family Residential, RSF. The RSF zoning is consistent with the City's Comprehensive Plan, which guides the property for Residential — Low Density use with a net density range of 1.2 to 4.0 units per acre. The proposed subdivision is at a net density of 1.85 units per acre. The RR district requires a minimum lot size of 2.5 acres. Development using the RR zoning would be inconsistent with the comprehensive plan. SUBDIVISION REVIEW WETLANDS Existing Wetlands Three aglurban wetlands exist on-site. Wetlands were delineated by Westwood Professional Services on July 15, 2004. The total area of wetlands is 0.14 acres (6,098 square feet). Wetland A located within the southwest corner of the property has been classified as a riverine, intermittent streambed with a mud bottom. The wetland is dominated by garlic mustard, ostrich fern and Jack-in-the-pulpit. No impacts to Wetland A are proposed. Wetland B located in the south-central portion of the property is classified as a Type 1 wetland. The wetland vegetation is dominated by box elder. No impacts to Wetland B are proposed. Wetland C located in the northwestern corner of the property is classified as a Type 1 wetland. The wetland's vegetation is dominated by box elder and Canada clearweed. No impacts to Wetland C are proposed. Wetland buffer widths of 16.5 feet to 20.0 feet must be maintained around all wetlands on-site. All structures must maintain a 40 -foot setback from wetland buffer edges. The building pad on Lot 9, Block 1 should be revised to reflect the wetland setback requirements. Wetland buffer areas should be preserved, surveyed and staked in accordance with the City's wetland ordinance. The applicant must install wetland buffer edge signs, under the direction of City staff, before construction begins and must pay the City $20 per sign. GRADING, DRAINAGE AND EROSION CONTROL The existing site is about 27 acres and has tree cover over approximately 18 acres (65% of the parcel). The existing parcel has a wide variety of grade changes within its limits. The site elevations range from a high of 1070± to a low of 1006±. These severe elevation differences make this site a challenging one to both develop and minimize grading. The plans propose to grade about 75-80% of the site for the 43 new house pads, a proposed street system, three cul-de-sacs and a stormwater pond. The proposed grading will prepare the site for full basement, look -out and walk -out type house pads. Retaining walls are proposed in numerous locations throughout the site. The applicant must be aware that any retaining wall over four feet in height must be designed by a registered civil engineer and a permit from the City Building Department must be obtained. In addition, encroachment agreements will be required for any retaining wall within a public easement. • 0 Pinehurst Rezoning & Subdivision with Variances Planning Case No. 04-36 December 7, 2004 Page 4 Staff does have a couple areas of concern in regards to the grading. The proposed house pad on Lot 27, Block 1 has steep slopes draining to or away from it on three out of the four sides. In staffs opinion, this grading design makes the lot undesirable at best. Also, there are two retaining walls just south of the lot which are adjacent to the proposed pond. If Lot 27 were eliminated, the pond could be shifted to the north which would eliminate the need for the southerly portions of the retaining walls. Because of the above reasons, staff is recommending that Lot 27, Block 1 be eliminated. In addition, it appears that a large portion of the western end of the site is being filled. This filling requires the use of five retaining walls on the western end of the site. Staff would recommend that the applicant lower the western end of the site in the area of the two private drives. This will help to minimize the overall amount of grading in the area, decrease the size of the retaining walls, and better match the existing topography of the area. The existing site drainage is encompassed within two different drainage areas. Under existing conditions, the western part of the site drains off site to an existing wetland to the west; the eastern part of the site drains off site to the south. Under developed conditions, the applicant is proposing to capture all of the street drainage, all of the front yard drainage and some rear yard drainage from the interior lots. This stormwater will be conveyed via storm sewer to a proposed pond in the south center of the site for treatment. The proposed pond must be designed to National Urban Runoff Program (NURP) standards with maximum 3:1 slopes and a 10:1 bench at the NWL. In addition, the proposed ponding must be sized to accommodate the drainage generated from the property to the north, as shown in the City's Surface Water Management Plan (SWMP). Drainage calculations for the site have been submitted and some changes remain. The applicant is required to meet the existing site runoff rates for 10 -year and 100 -year, 24-hour storm events. Storm sewer sizing calculations must be submitted at the time of final plat application. The storm sewer must be sized for a 10 -year, 24 -how storm event. Drainage and utility easements must be dedicated on the final plat over the public storm drainage system including ponds, drainage swales, and wetlands up to the 100 -year flood level. Proposed erosion control must be developed in accordance with the City's Best Management Practice Handbook (BMPH). Staff recommends that Type II silt fence, which is a heavy duty fence, be used adjacent to the existing wetland, existing creek area, and around the proposed pond. In addition, tree preservation fencing must be installed at the limits of tree removal. Erosion control blankets are recommended for all of the steep 3:1 slopes with an elevation change of eight feet or more. All disturbed areas, as a result of construction, must be seeded and mulched or sodded immediately after grading to minimize erosion. The applicant should be aware that any off-site grading will require an easement from the appropriate property owner. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with detailed haul routes. Storm Water Management The proposed development is required to maintain the existing runoff rates. Preliminary storm water calculations submitted with the plans illustrate that storm water ponds located on Outlot B have been properly sized to handle post -development 2, 10 and 100 -year storm events for the site. However, the City's Surface Water Management Plan shows that a regional pond should be constructed to Pinehurst Rezoning & Subdivision with Variances • Planning Case No. 04-36 December 7, 2004 Page 5 accommodate storm water runoff from the Shively Addition. Pond A should be expanded to the northeast to accommodate future development of this site. Final storm water calculations should be submitted to ensure the appropriate drainage areas are captured and that proposed storm water ponds meet all requirements. Detailed plans for proposed storm water infrastructure (including catch basins and outlet structures) should be submitted. Erosion Control Erosion control blanket should be installed on all slopes greater than or equal to 3:1. All exposed soil areas should have temporary erosion protection or permanent cover year round, according to the following table of slopes and time frames: Type of Slope Time (maximum time an area can remain unvegetated when area is not active) be' worked) Steeper than 3:1 7 Days 10:1 to 3:1 14 Days Flatter than 10:1 21 Days These areas include constructed storm water management pond side slopes, any exposed soil areas with a positive slope to a storm water conveyance system, such as a curb and gutter system, storm sewer inlet, temporary or permanent drainage ditch or other man-made systems that discharge to a surface water. Daily scraping and sweeping of public streets should be completed any time construction site soil, mud, silt or rock is tracked or washed onto a paved surface or street that would allow tracked materials or residuals of that material to enter the storm water conveyance system. Construction site access points should be minimized to controlled access points with rock entrance and exit pads installed and maintained throughout construction. SURFACE WATER MANAGEMENT FEES Water Quality Fees Because of the impervious surface associated with this development, the water quality fees for this proposed development are based on single-family residential development rates of $1,028/acre. Based on the proposed developed area of 23.36 acres, the water quality fees associated with this project are estimated to be $24,014. Water Quantity Fees The SWMP has established a connection charge for the different land uses based on an average city wide rate for the installation of water quantity systems. This cost includes land acquisition, proposed SWMP culverts, open channels, and storm water ponding areas for runoff storage. Single-family residential developments have a connection charge of $2,545 per developable acre. This results in a water quantity fee of approximately $59,451 for the proposed development. Pinehurst Rezoning & Subdivision with Variances • Planning Case No. 04-36 December 7, 2004 Page 6 SWMP Credits This project proposes the construction of one NURP pond. The applicant will be credited for water quality where NURP basins are provided to treat runoff from off-site. This will be determined upon review of the ponding and storm sewer calculations. Credits may also be applied to the applicant's SWMP fees for the provision of outlet structures. No credit will be given for temporary pond areas. Based on the proposed developed area of 23.36 acres, the estimated total SWMP fee, due payable to the City at the time of final plat recording, is $83,465. OTHER AGENCIES The applicant must apply for and obtain permits from the appropriate regulatory agencies (e.g., Riley - Purgatory -Bluff -Creek Watershed District, Minnesota Pollution Control Agency (NPDES Phase II Construction Permit), Minnesota Department of Natural Resources (for dewatering)) and comply with their conditions of approval. UTILITIES Municipal sewer and water service is available to the site from Manchester Drive and water service is available from Galpin Boulevard. The water and sewer mains will be extended north from Manchester Drive to serve the site. The watermain will then be looped with the existing 12 -inch diameter main along Galpin Boulevard. In addition, water will be extended to the north property line for future development of the parcel to the north. The water and sewer is also proposed to be extended within two private streets (D and E) off of Street A. The watermain in Private Drive D is proposed to be connected with the existing watermain from the Brenden Court private street to the west. This watermain extension can be directionally bored which will preserve the existing trees within the western side of the site. The watermain connection will provide a "looped" system for the majority of the western side of the site. The applicant is also proposing a second gravity sewer line to serve the western two-thirds of the site. This sewer line, which runs from MH -18 to an existing manhole in Lake Lucy Road, is proposed to go south outside of the pavement and right-of-way, through Lot 17, Block 1 and cross over City -owned property prior to connecting to the existing sewer line in Lake Lucy Road. Staff is recommending that this western sewer line be eliminated for the following reasons. First, the City -owned land that the sewer would run through is very steep. City staff has concerns with access and maintenance of such a line on a steep slope. Second, the City -owned property was originally acquired as a possible future well site. The location of the sewer line on the property could limit the possible well locations. Finally, the existing sanitary line in Manchester Drive was stubbed to this property to serve the entire site. City Code requires a minimum 30 -foot wide public easement over the public sewer and watermain within private streets. Due to the depth of the proposed sanitary sewer from MH -20 to M11-17, however, the required easement width will need to be increased to 50 feet. The underlying property has been previously assessed for sewer and water improvements and those assessments have been paid. The sanitary sewer and water hookup charges along with the Lake Ann Interceptor charge will be applicable for each of the new lots. The 2004 trunk hookup charge is $1,458.00 per unit for sanitary sewer and $2,814.00 per unit for watermain. The total 2004 Lake Ann Pinehurst Rezoning & Subdivision with Variances • Planning Case No. 04-36 December 7, 2004 Page 7 Interceptor charge is $2,102 per unit and the SAC fee is $1,425.00 per unit. All of these charges are based on the number of SAC units assigned by the Metropolitan Council. Sanitary sewer and water - main hookup fees may be specially assessed against the parcel at the time of building permit issuance. All of the utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. Upon completion of the utility improvements, the utilities will be turned over to the City for maintenance and ownership. The applicant is also required to enter into a development contract with the City and supply the necessary financial security in the form of a letter of credit or cash escrow to guarantee installation of the improvements and the conditions of final plat approval. The applicant must be aware that all public utility improvements will require a pre -con meeting before building permit issuance. Permits from the appropriate regulatory agencies will have to be obtained, including but not limited to the MPCA, Department of Health, and Carver County. STREETS The plans propose two full accesses to the site; one off of Galpin Boulevard from the east side and the other from the extension of Manchester Drive to the south. Additionally, Street B will be extended to the north property line to allow for a future street connection with Crestview Drive when the property to the north is developed. A temporary cul-de-sac turnaround for emergency vehicles will be required at the north end of Street B along with a sign stating that the road will be extended in the future. All of the proposed public streets comply with the minimum required right-of-way and pavement widths. For Street C, the applicant is proposing a very wide right-of-way with a large island in the center. Due to maintenance concerns with such a large right-of-way, staff is recommending that Street C be revised to be a standard cul-de-sac. Also, Galpin Boulevard is designated as an arterial road in the city. Per City Code, arterial roads are required to have 100 feet of total right-of-way or 50 feet from each side of the centerline of the road. As such, this development is required to provide enough additional platted right-of-way which results in 50 feet of right-of-way on the western side of the Galpin Boulevard centerline. As with past developments that access off of Galpin, a right -turn lane into the site will be required to be constructed. The tum -lane must meet Carver County design requirements. LANDSCAPINGITREE PRESERVATION Tree canopy calculations have been submitted for the Pinehurst development. They are as follows: Total upland area (excluding wetlands) 27.48 ac. Baseline canopy coverage 65% or 17.92 ac. Minimum canopy coverage allowed 46% or 12.64 ac. Proposed tree preservation 26% or 7.23 ac. The developer does not meet minimum canopy coverage allowed; therefore, the difference between the baseline and proposed tree preservation is multiplied by 1.2 to calculate the required replacement plantings. Difference in canopy coverage 235,660 SF or 5.41 ac. Multiplier 1.2 Pinehurst Rezoning & Subdivision with Variances • Planning Case No. 04-36 December 7, 2004 Page 8 Total replacement 282,792 SF Total number of trees to be planted 260 trees The applicant has proposed 262 trees in their landscape plan.

Planning Case No. 04-36 On December 7, 2004, the Chanhassen Planning Commission met at its regularly scheduled meeting to consider the application of Plowshares Development, LLC for rezoning property from Rural Residential, RR, to Single -Family Residential, RSF, preliminary plat approval for 43 lots, two outlots and right-of-way for public streets with variances for the use of private streets. The Planning Commission conducted a public hearing on the proposed rezoning and subdivision with variances preceded by published and mailed notice. The Planning Commission heard testimony from all interested persons wishing to speak and now makes the following: FINDINGS OF FACT 1. The property is currently zoned Rural Residential (RR). 2. The property is guided in the Land Use Plan for Residential — Low Density. 3. The legal description of the property is: Lots 1 & 2, Old Slocum Tree Farm 4. The Zoning Ordinance directs the Planning Commission to consider six (6) possible adverse affects of the proposed amendment. The six (6) affects and our findings regarding them are: a. The proposed action has been considered in relation to the specific policies and provisions of and has been found to be consistent with the official City Comprehensive Plan, including meeting the net density goal of 1.2 to 4.0 units per acre with a net density of 1.85 units per acre, development within the Metropolitan Urban Service Area, residential low density development in appropriate area in a manner that reinforces the character and integrity of existing single family neighborhoods, providing adequate internal street linkages, and the preservation of natural resources. b. The proposed use is compatible with the present and future land uses of the area. C. The proposed use conforms with all performance standards contained in the Zoning Ordinance, subject to the granting of the setback variances to appropriate lots for tree preservation purposes. d. The proposed use will not tend to or actually depreciate the area in which it is proposed, but should enhance the residential character of the area. 0 0 e. The proposed use can be accommodated with existing public services and will not overburden the city's service capacity. f. Traffic generation by the proposed use is within capabilities of streets serving the property- The roperty The Subdivision Ordinance directs the Planning Commission to consider seven possible adverse affects of the proposed subdivision. The seven (7) affects and our findings regarding them are: a. The proposed subdivision is consistent with the zoning ordinance; b. The proposed subdivision is consistent with all applicable city, county and regional plans including but not limited to the city's comprehensive plan; C. The physical characteristics of the site, including but not limited to topography, soils, vegetation, susceptibility to erosion and siltation, susceptibility to flooding, and storm water drainage are suitable for the proposed development; d. The proposed subdivision makes adequate provision for water supply, storm drainage, sewage disposal, streets, erosion control and all other improvements required by this chapter; e. The proposed subdivision will not cause significant environmental damage; f. The proposed subdivision will not conflict with easements of record, but will dedicate all required easements; and g. The proposed subdivision is not premature. A subdivision is premature if any of the following exists: 1) Lack of adequate storm water drainage. 2) Lack of adequate roads. 3) Lack of adequate sanitary sewer systems. 4) Lack of adequate off-site public improvements or support systems. 6. In order to permit private streets, the city must find that the following conditions exist: a. The prevailing development pattern makes it unfeasible or inappropriate to construct a public street. In making this determination, the city may consider the location of existing property lines and homes, local or geographic conditions and the existence of wetlands. Extension of a public street to serve the six homes on the west end of the site would significantly impact an environmental area on the property - 2 0 0 b. After reviewing the surrounding area, it is concluded that an extension of the public street system is not required to serve other parcels in the area, improve access, or to provide a street system consistent with the comprehensive plan. Public streets are not necessary to access the property to the west, which is currently developed with single-family homes and accessed via Brenden Court. C. The use of the private street will permit enhanced protection of the city's natural resources including wetlands and forested areas. The use of limited private streets preserves approximately 2.8 acres of woodlands. 7. VARIANCE FINDINGS — PRIVATE STREET a. The hardship is not a mere inconvenience, but provides a means for preserving natural features on site. b. The hardship is caused by the particular physical surroundings, shape or typographical conditions of the land. C. The conditions upon which the request is based are unique and not generally applicable to other property. d. The granting of the variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of the subdivision ordinance, the zoning ordinance and comprehensive plan. 8. The planning report #04-36 dated December 7, 2004, prepared by Robert Generous, et al, is incorporated herein. The Planning Commission recommends that the City Council approve the rezoning and preliminary plat with a variance for private streets. ADOPTED by the Chanhassen Planning Commission this 7th day of December, 2004.

These comments are not all inclusive and further comments and concerns may evolve as this project progresses and changes. Galpin Boulevard in the location of this proposed development is presently on the County road system and is identified as County Road 117. The long term plans for this portion of County Road 117 include a turnback of this roadway to the City of Chanhassen. Initial conversations concerning this potential turnback had begun five or six years ago but have been discontinued at this time. The comments that follow would be our comments concerning this proposal if this roadway is to remain on the County system. Right-of-way widths listed in the Eastern Carver County Transportation Study for roadways functionally classified as Collector (Class 1) are: Urban Undivided Rural Undivided 2 -lane Roadway 2 -lane Roadway Minimum Recommended Minimum Recommended 80' 100' 110' 120' Urban Undivided Rural Undivided 4 -lane Roadway 4 -lane Roadway Minimum Recommended Minimum Recommended 100' 110' 140' 170' County Road 117 (Galpin Boulevard) is functionally classified as a Collector (Class 1) roadway in the Eastern Carver County Transportation Study. The 50 foot from centerline corridor shown on the preliminary plat would provide for a potential minimum 100 foot corridor for a two lane urban roadway. The city may wish to consider an even wider highway corridor along the proposed subdivision if a separate trailway is to be constructed along the county highway. 0 0 Additional width may also be needed to accommodate public utilities and landscaping. 2. An access permit from Carver County will be required for the proposed street entrance onto CR 117. Construction of a right tum lane off of CR 117 into the development will be a requirement included in the access pen -nit. 3. Any public utility lines that are to be installed within the CR 117 right-of-way are subject to the utility permit requirements of Carver County. 4. Any proposed grading and installation of drainage structures within the right-of-way of CR 117 is subject to review and approval of Carver County. 5. Development activities (including the installation of both public and private utilities needed to serve the development site) that result in any disturbance of the county highway right-of-way (including tree removal, trench settlements, erosion, and sediment deposits) need to be completed in a manner that leaves the right-of-way in "as good or better condition" than what existed prior to construction. It is requested that the city include a provision in the developer's agreement that requires the developer to be ultimately responsible for the final condition of the county highway right-of-way. A clear understanding of this responsibility will result in fewer project oversight problems for both the County and the City. 6. Any trees or landscaping completed within the right-of-way must be approved by the County. When locating shrubs and trees, consideration should be given to maintaining an acceptable sight distance at the CR 117 intersection. Any trees or shrubs overhanging into the right-of-way could be subject to trimming for safety or overhead utility consideration. 7. As this area develops, traffic volumes will increase. Carver County considers any potential noise abatement improvements to be the responsibility of the developer. Thank you for the opportunity to comment on the preliminary plat for the proposed development. 0 0 City of Chanhassen Attention: Planning Commission 7700 Market Boulevard P.O. Box 147 Chanhassen, MN 55317 City of Chanhassen Planning Commission, RECEIVED NOV 10 2004 CITY OFCHANHASSEN This letter is intended to address the proposed development of the "Slocum Tree Farm". The city has indicated that it intends that the aforementioned development must affect the neighborhood situated on Crestview Drive, in Chanhassen. This is primarily due to a proposed road that would connect the new development with the Crestview Drive neighborhood now or in the future. Introduction The Crestview Drive neighborhood was created during the late Fifties. The area is around 25 acres. The road began as private. Over the course of 20 years, the road was extended and a cul-de-sac was added. During the late 70's, the city took control of the road when paving, water and sewer where added. A total of 8 houses exist on this cul-de- sac. The yards are large and private. Only two properties are larger than 1.25 acres. They are the Jackson property and the recently sold Shultz property. All the properties on Crestview Drive are fairly well kept up. A simple review of permits granted over the years demonstrates this. Simply put, this neighborhood has seen little change/development. There are few like it — especially in this city. It is fair to say that a sound majority of the folks here (the Crestview Drive neighborhood) like the road the way it is and would like to see it continue in its current form It is not a zone of transition or even close to one (as a geographer would put it). This area is not run down, in need of change, not unattractive or a hazard in any way. Several Crestview Drive homeowners have inquired on the city's intentions. Each time some one asks about the proposed road that connects "our" property to the Slocum Development, a new reason appears. The city has cited the following: 1. Parts of the Crestview Drive neighborhood might be developed and that requires a connecting road. 2. Crestview Drive needs to be something other than a culde-sac so school buses can use it. 3. Utilities need to be connected 4. It would be in everyone's interest to get rid of that "ugly" cul-de-sac. 5. People on Crestview Drive need access to the new development or visa versa. 0 0 Each of the above items needs to be addressed. It struck a number of people that the reasons given were somewhat "superficial". Hopefidly, the planning commission has left room for discussion. Parts of the Crestview Drive neighborhood might be developed and that requires a connecting road. Point number one suggests that without a road, no other development can take place on Crestview Drive. The Jackson family (one of the two lots that potentially might be divided) inquired about the needs. Interestingly, the city said that water would need to be extended up the street at a cost of $8000 per household. At no time did anyone suggest that additional streets would be needed. At this time no one, or at least, a majority of people doesn't want an organized development. Sure, folks all understand that a few houses (2-5) might be added someday. Anything beyond that (a development) is not wanted. The argument against the proposed road can also be tied to neighborhood size. Crestview Drive currently has 8 houses on it. If the two larger lots are split and rezoned (another distasteful thought) some homes might be added. For arguments sake, let us assume an additional 5 houses. The resulting total of 12 houses shouldn't require anything more than a cul-de-sac. The current Slocum development supports this. The proposed neighborhood actually has 15 or 16 houses on a cul-de-sac! This makes people ask why a road is needed. If this comes down to a development at the end of Crestview Drive, then make it part of Pinehurst. If this is done Crestview remains a cul-de-sac and bears no burden Nothing changes for the area. Here any and all questions are addressed separately from Crestview Drive. The proposed road would need to be moved fiuther west so it doesn't affect the Abblett property. This is reasonable. Maybe the road has nothing to do with developing Crestview Drive. Perhaps the Slocum development needs the road. If this is the case, reduce their development. Crestview Drive doesn't need to be burdened with their shortcomings. Didn't past discussions put a road through the Brenden Pond, 3'd addition, though the "outlot A" of Pinehurst (see Pinehurst drawing)? The connecting road should not he Crestview's concern. If the above statement is true, why force another neighborhood to support an unwanted violation. How could the Crestview neighborhood be compensated? It affects every family on Crestview. It adds traffic that otherwise wouldn't be there. When is the City of Chanhassen going to force changes to the existing streets? Does Crestview have to pay for that? Is the city going to take property to make the streets wider? Where does the harassment end? In the past, Chanhassen has stated that, neighborhood improvements won't be made unless every family agrees. Is this no longer the case? 0 0 Why does the Slocum (Pinehurst) development need three access points? Other neighborhoods have hundreds of families and three access points. Several examples can be found all the way up County Road 17! What is special here? Crestview Drive needs to be something other than a cul-de-sac so school buses can use it. A city employee did indicate that there was concern about school bus access. In the first place, no one has children on Crestview at this time. Secondly, other neighborhoods (with multiple access points and connecting roads) seem to have their school age children picked up, not in the neighborhood, but along the main road. Interestingly enough, other neighborhoods aren't affected in the same way as ours is. A fabulous example of this is on Lake Lucy Road in between CR 17 and Powers Blvd. Again, people ask why does Crestview Drive need to be concerned with this? Why is Crestview so special? Utilities need to be connected. The city has indicated that it wants to "connect" utilities. We know this is not a problem. The folks developing the Slocum Tree Farm (Pinehurst) have access to utilities via Woodridge Heights, Brenden Pond and CR 17. Crestview Drive has water and sewer. If it needs to be extended it can be done reasonably ($8000 per family according to the Jackson family). Again, the Crestview neighborhood is being burdened. Why? It would be in everyone's interest to get rid of that "ugly" cul-de-sac. This is this the weakest argument of all. Personally, we bice the large cul-de-sac. It has served Crestview and the City for plowing purposes. We all have mature trees and don't have to see each other, much less the cul-de-sac. Our so-called `ugly cul-de-sac" has never come up at neighborhood gatherings or polite discussion. So if the city doesn't mind, we'd lace to keep itl People on Crestview Drive need access to the new development or visa versa. May we say, `ho thank you to Pinehurst access"? Crestview Drive will remain much safer as a cul-de-sac. All concerned feel that it keeps us safer, secluded and buffered from the bland, "cookie cutter" houses or mini -mansions this city seems to prefer. The Crestview neighborhood likes it's large secluded lots and it's privacy. Conclusion The homeowners on Crestview Drive would like you to reconsider the proposed road. We would prefer to be an "independent" neighborhood as we have been for years. May we respectfully decline the privilege of serving a developers needs? If the Pinehurst 0 0 DeMOPIDUAISkm m Tree Farm) can't support their proposed development, then reduce the amber of homes. Other arguments do not seem credible for a road. The size of our road is fine as it stands, it can support Crestview Drive's and the City's needs now and in the future. We aren't concerned about school buses (apparently other neighborhoods aren't either). Homeowners know they have access to utilities and are satisfied. We like our cul-de-sac. It is not ugly. It has served us welland willeontinue to. No benefits seem to exist for Crestview Drive.

Box 147 Chanhassen, NW 55317 City of Chanhassen Planning Commission, RECEIVED NOV 12 2004 CITY OF CHANHASSEN Additional questions and .concerns have been arisen concerning the proposed Pinehusrt Development (Slocum Tree Farm) road that would connect to Crestview Drive. The city notified most Crestview Drive residents about the proposed development. Because of this, some homeowners have done some investigating. Additional information that concerns Crestview Drive, Pinehurst and potentially the City. of Chanhassen has been found. The City of Chanhassen planning commission may not have notified the entire .Crestview Drive neighborhood. It is currently understood that residents within a certain distance of proposed changes need to be notified. At least two families appear to not be aware of the situation. The proposed change to Crestview affects .every one on Crestview Drive. The powers that be may want to check. The scope of the notification really should change as well. Are other neighborhoods in close proximity going to be connected too? What about traffic where none existed? For example, Crestview Circle is affected in two ways. First, additional traffic at the intersection where CR 17, Crestview Drive and their road come together might be an issue. Secondly, due to the current attitude of the planning commission, their road may not remain a cul- de-sac either. They may want to voice their opinions now. Perhaps the previous comments are inaccurate. Other information residents have points to that. Concerns over proposed road, the developer, partners of the developer and the City of Chanhassen have arisen with additional information. It is now the residents understanding that a person or group associated with the Pinehurst development has intentions of developing the 3+ acres at the end of the Crestview Drive cul-de-sac. Accordingly, the Shultz property has been already split into lots. It appears that the City may want to "force" the Pinehurst connection to Crestview to favor some one or a group associated -With Pi'turst. Frankly, no one is interested in .being associated with Pineburst in any way. In fact, there would be no reason for the connection other than to favor the people associated with the Shultz property (at the endofthe cut -de -sae). Comments from homeowners suggest other motives/concerns may be in play. Relocating the road west of its proposed position (see enclosed drawing) would seem to eliminate the issues at hand. It should never be connected in any way to Crestview Drive. This is the easiest solution that has no ill effect on any party involved. Residents are not against one or two houses. It would allow us to keep our cul-de-sac. Our style of neighborhood with large lots wouldn't change either. We don't care for a full-blown development. If the is the case, move the mad. It is understood that the Pinehurst, and any additional development connected to it, would be serviced in an acceptable way with disturbing us (no connecting road). Examples of this exist all over our city. Access to two major roads is beyond what most, larger neighborhoods have. Conclusion Several things have happened. Residents have, conveniently, not been fully informed. No discussion has ensued on a development at the end of Crestview Drive. I'm sure that small lots and "cookie cutter" P.i ehurst houses are the wish. This is not of interest to the homeowners on Crestview Drive. Property owners here like their large city lots and privacy. A change in our situation is not of interest. Certainly, our neighbors and us are not obligated to share in a developers "vision". This would be especially true because of the cost and mcimv€mence that would be incurred. One would hope that collusion is not something occurring_ between the people associated with Pinehurst and anyone at the city. Forcing the residents of Crestview Drive down an unwanted path for no concrete purpose, under protest, makes every one ask more and deeper questions. This is especially true when simple solutions exist. Certainly this is not a 0 0 test of wills either. I know that most our city employees are exceptional and in -tune to the community. The toad could be moved west so it does not influence Crestview Drive in any way. The simplicity and effectiveness of this should be obvious. No change to Crestview Drive eliminates homeowner concerns. The development can continue unopposed for the most part. Thank you for your time and consideration, (( w Paul Tungseth et air �� � h / ��-� ! �w �U �- � §\ ° { A ¥ �. �.� � . � 0 0 City of Chanhassen Attention: Planning Commission 7700 Market Blvd. P.O. Box 147 Chanhassen, MN 55317 City of Chanhassen Planning Commission: This letter is to give additional support to Mr. Tungseths letter that has been presented to you. We were unaware, until Thursday, November 11, that Lecy Bros. Development is planning a development at the top end of Crestview Drive. No notification was ever sent to us, and we feel we have the right to be given notice of any changes to our street and/or properties. We know of the proposed Pinehurst development and have concerns about the projected extension of our road to tie in to that development. As in Mr. Tungseths letter, we strongly agree that there is no reason to join the neighborhood of Crestview Drive to the Pinehurst Development. With the Lecy Brothers development planned for the end of Crestview Drive, it makes much more sense to connect this new development to the Pinehurst Development. This will leave Crestview Drive residents to not have to undergo any changes to our street and neighborhood, that we feel are not needed. This in no way improves our neighborhood. As indicated by the petition signed by the majority of the residents of Crestview Drive, which you have already received, we as a neighborhood, do not wish to have our neighborhood or our quiet dead end eliminated, or changed. Concerns: I. Will Crestview Drive be widened? 2. Will City Water have to be extended to the end of Crestview Drive? 3. Will sidewalks be put in? For us personally, if Crestview is widened, we will lose a large amount of mature trees that add value and beauty to our property. These potential changes will lead to an assessment to the residents of Crestview Drive, which we feel is an unnecessary expense. None of these proposed changes benefit our neighborhood. Do what you will with the new developments, but don't include them into our established neighborhood. 0 0 We specifically sought out this home because it was on a dead end street and in a long established neighborhood, all homes being on larger private properties that give all of us a setting that is hard to find. We enjoy the quiet and solitude that this neighborhood offers, and don't want to see it destroyed C1/.GGcerely, 1� Charles & Bever y Jackson 2110 Crestview Drive Excelsior, MN 55331 0 0 CITY OF CHANHASSEN AFFIDAVIT OF MAILING NOTICE STATE OF MINNESOTA) ) ss.

We have worked hard with City Staff and the Planning Commission to create a quality neighborhood that will be a wonderful addition to the city. Below you will find an explanation of a few of the remaining items for discussion on Jan 1 &. We appreciate your time consideration and look forward to a successful project. Condition O: A standard cul-de-sac turnaround for emergency vehicles will be required at the north end of Street B. This recommendation by the Planning Commission eliminates the connection between the Pinehurst and Shively neighborhoods. City Staff and Plowshares Development believe the connection should be made and is vital for the following reasons: (Exhibit A) I. City Staff is requiring a road connection to the Shively Addition based upon the Transportation policy in the Comprehensive Plan: a "!Ls part ofplatting, eacb detrlopment sbould provide dedication and improvement of public streets consistent nntb the standards found in city ordinances. The city w Ilpm rete the pmtowN of street andpedestrian connection to maximum safety and ease of access. " P. 55 b. `Tt is the city's polity to require interconnections between neighborhoods to foster a sense of community, to improve safety and to provide convenient access for residents. " P. 76 2. It makes sense to plan for the future. Eventually, the properties along Crestview Drive will redevelop into a more intensive use — at which time the road connection will be important to the City in order for it to provide essential city services. 3. If the City Council determines that a connection is not justified, Plowshares would ask that the design alternative (Exhibit B) with a private street and cul-de-sac be approved in its place. This design eliminates a road connection, but incorporates the trail connection and an easement for a sewer connection.

Lot 27 conforms to all city ordinances and does not require a variance. a. Lot size 18,232 sq ft — City ordinance requires a 15,000 sq ft minimum Lot 27 is roughly 20% larger than City requirements. b. Front, rear and side setback meet or exceed City requirements. c. Drainage and slope ratios meet or exceed City engineering standards. 2. The site has been designed to maximize tree preservation and to provide for regional ponding. Eliminating Lot 27 does not significantly reduce the retaining walls and saves no additional trees. At City Staffs request, the proposed pond has already been oversized to incorporate both the Pinehurst and Shively addition developments. 3. Plowshares Development and Lundgren Brothers have a long history of quality home building. We would not propose a lot that had potential liability issues. We are confident in the design and stand behind out proposal In additional we are proposing the following to alleviate staffs concerns: a. Westwood Professional Services (the project engineer) has finalized an engineering report and illustration that demonstrates how site drainage will work. This will alleviate Staffs concerns related to drainage. See Exhibit C & D. b. Plowshares proposes to have the sodded and landscaped lot surveyed to ensure compliance with the final engineered plan. Condition Q: The applicant shall work with staff to further investigate the feasibility of a sewer connection before action is taken to delete the western sanitary line; all sanitary sewer must drain to Manchester Drive. Plowshares Development agrees with the Planning Commission on this recommendation for the following reasons: 1. Without the sewer connection to Lake Lucy, the depth of the sewer in the Pinehurst development will be excessively deep (40-45�. Under this scenario the proposed sewer line will be difficult to access and expensive to maintain. 2. Staff had raised concerns about accessibility of the proposed line for cleanout and maintenance. Since the Planning Commission meeting, Plowshares has worked with staff to provide an alternative that alleviates their concerns. 'Ibis alternative avoids 40-45' deep sanitary sewer and provides easily accessible maintenance of the sewer line. in the business of buying selling, and developing land phone 952.361.0832 fax 952.361.0833 1851 Lake Drive West, Suite 550 Chanhassen, Minnesota 55317 www. p lowsharesdeve lop nne ntxom 0 PLOWSHARES DEVELOPMENT, LLC Condition 8: The applicant will work with staff to incorporate a tot lot or similar Playground facility within this development which will help preserve trees: Plowshares Development disagrees with the Planning Commission recommendation for the following reasons: 1. City Staff and the Park Board did not recommend a tot lot or park in the Pinehurst neighborhood. Therefore, City Staff has indicated that they are not interested in providing a parkland dedication credit for the Pinehurst Development 2. The City's Park Plan does not indicate a park in the location of the Pinehurst neighborhood. This is primarily due to the close proximity of the following park and recreation areas: a. Minnetonka West Middle School is immediately adjacent to the Pinehurst Development The middle school provides ample ball fields and tennis courts. b. Pheasant Hill Park is within a'/s mile of the neighborhood and within the 'h mile standard of city park spacing. Pheasant Hill provides a large open space and tot lot/playground equipment c. Lake Minnewasbta Regional Park is within a % mile of the neighborhood. 3. Plowshares Development and Lundgren Brothers have a long history of building quality neighborhoods within the City of Chanhassen and have a deep understanding of our buyer profile. Our combined experiences suggest that the families of the Pinehurst neighborhood will prefer private backyard playground equipment over a tot lot 4. Plowshares Development is willing to donating 2.8 acres (Outlot A) to the City that could be used for parkland or tot lot at a future date. Condition 9. Provide an access trail from this neighborhood to Minnetonka West Middle School. Plowshares Development agrees with the Planning Commission and Staff recommendation. Staff and Minnetonka School District have indicated that the best location for the trail access is through the Shively addition to the north. This connection will provide excellent access to the middle school amenities and furthers the rational of connecting the Shively and Pinehurst neighborhoods. See Exhibit A & B.

CLOUD BRAINERD Based on discussions with staff and comments made at the Planning Commission meeting, the main concern on lot 27 is drainage and more specifically drainage from the back yards of lots 24-26. The City/Watershed requires that the lowest opening of structures adjacent to a pond, as is the case with Lot 27, be a minimum of 3 feet above the 100 -year high water level of the pond. Lot 27's lowest opening exceeds the city's requirements at 3.1 feet above the 100 -year high water level mark. Lowest openings also need to be set a minimum of 2 feet above the emergency overflow of the pond. Lot 27 is proposed to be 3 feet above the emergency overflow which exceeds the requirements of the City and Watershed. To facilitate proper drainage, a catch basin is proposed on the side lot line. Intercepting water from the swale will be the primary function of the inlet to prevent runoff across the driveway, over the curb and gutter, and over sidewalk within the street right-of-way. Since the Planning Commission meeting, a check on the depth of water that would be in the swale on the side lot line of Lot 27 was made. The approach was conservative. It was assumed that the front and back halves of the building areas from lots 24, 25, and 26 would enter the proposed Swale on the side of Lot 27. Typically, the front half of homes drain to the street. The drainage area used for the calculation is overstated by incorporating additional area not normally included. Based on the conservative approach, the computed depth of water during a 100 -year event flowing in the swale would be less than 2 inches based on a 3' wide Swale. Staff had a concern in previous meetings that the swale on the side of Lot 27 would not get constructed properly. Normally, a record grading plan would be required after the mass grading operation is complete and then once again immediately after the home is constructed. In addition to this requirement, Plowshares and Lundgren Brothers have asked Westwood to survey the lot after the landscaping and sodding is complete to ensure to the homeowner and the City that the drainage will not be altered from the design on the grading plan The grades around the building pad are designed to convey all surface water away from the building. This is standard practice for grading design and prevents surface water from infiltrating down a foundation wall and into a basement. Lot 27 is proposed as a properly functioning and desirable lot based on solid design and drainage verification. The lot is in conformance with City codes for area, setbacks, elevations above the 100 -year high water level of the pond, and general drainage away from the building pad. From an engineering perspective, Lot 27 mets and exceeds City requirements and standard engineering practices. Westwood has designed and overseen the construction of many lots with similar design and sees no cause for alarm related to this lot. As Project Manager for the Pinehurst Designing the Future Todagsince 1972 Chanhassen City Council Members December 30, 2004 Page 2 Development, I am confident that the combined experience of Plowshares Development, Lundgren Brothers, and ourselves will ensure that Lot 27 is properly designed and constructed.

SURFACE WATER MANAGEMENT PLAN (SWMP) SURFACE WATER MANAGEMENT FEES (Note — SWMP fees were revised effective January 1, 2005.) Tha City o Chanhassen • A growing community with clean lakes, quality schools, a charming downtown, Ihriviag businesses, winding Ira iIs, and beautiful parks. A great place to live, work, and Olay. Final Plat — Pinehurst Addition • Planning Case 04-36 March 14, 2005 Page 2 Water Quality Fees Because of the impervious surface associated with this development, the water quality fees for this proposed development are based on single-family residential development rates of $1,093/acre. Based on the proposed developed area of 23.68 acres, the water quality fees associated with this project are estimated to be $25,882.24. Water Quantity Fees The SWMP has established a connection charge for the different land uses based on an average City wide rate for the installation of water quantity systems. This cost includes land acquisition, proposed SWMP culverts, open channels, and storm water ponding areas for runoff storage. Single-family residential developments have a connection charge of $2,705 per developable acre. This results in a water quantity fee of approximately $64,054.40 for the proposed development. SWMP Credits The developer is providing storm water ponding for off-site developments. For the oversizing of the pond, the developer is being granted a credit of $11,902.77. For the installation of the outlet control structure, the developer is provided an additional credit of $2,500.00. Based on the proposed development area of 23.68 acres, the estimated total SWMP fee, due payable to the City at the time of final plat recording, is $75,522.87. WETLANDS Three ag/urban wetlands exist on-site. Wetlands were delineated by Westwood Professional Services on July 15, 2004. The total area of wetlands is 0.14 acres (6,098 square feet). No wetland impacts are proposed. LANDSCAPING AND TREE PRESERVATION The developer has revised the plan to attempt to preserve additional trees. While they have been able to increase some areas of tree preservation, they will have to eliminate trees in other areas, especially for the utility extensions. The landscape plan shall include a minimum of 260 trees. A final revised plan must be submitted to the City for approval prior to recording the final plat. PARK & RECREATION Comprehensive Park Plan The proposed Pinehurst development is located within the municipal park service boundaries of Pheasant Hill Park and Herman Field Park. In addition, the property is directly adjacent to the Minnetonka Middle School West campus and a short drive or walk from Lake Minnewashta Regional Park. These three facilities will provide future residents significant access to park and r Final Plat — Pinehurst Addition Planning Case 04-36 March 14, 2005 Page 3 open space resources. No additional parkland dedication is recommended as a condition of this plat. Full park fees shall be collected at the rate in force at the time of final plat. For the 41 additional single-family lots, a total park fee of $164,000.00 will be required based on 2005 park fees. Comprehensive Trail Plan The site does not contain or directly access any portion of the City's trail plan. A sidewalk or trail connection to the Middle School Campus should be included as a condition of approval. In addition, appropriate sidewalks connecting to the east and south should be included. GRADING, DRAINAGE & EROSION CONTROL The existing site is about 28 acres and has tree cover over approximately 18 acres (65% of the parcel.) The existing parcel has a wide variety of grade changes within its limits. The site elevations range from a high of 1070± to a low of 1006±. These severe elevation differences make this site a challenging one to both develop and minimize grading. The plans propose to grade about 75-80% of the site for the 43 new house pads, a proposed street system, four cul-de- sacs and a stormwater pond. The proposed grading will prepare the site for full basement, look- out and walk -out type house pads. Retaining walls are proposed in numerous locations throughout the site. The applicant must be aware that any retaining wall over four feet in height must be designed by a registered civil engineer and a permit from the City building department must be obtained. In addition, encroachment agreements will be required for any retaining wall within a public easement. The existing site drainage is encompassed within two different drainage areas. Under existing conditions, the western part of the site drains off-site to an existing wetland to the west; the eastern part of the site drains off-site to the south. Under developed conditions, the applicant is proposing to capture all of the street drainage, all of the frontyard drainage and some rearyard drainage from the interior lots. This stormwater will be conveyed via storm sewer to a proposed pond in the south center of the site for treatment. The proposed pond has been designed to National Urban Runoff Program (NURP) standards with maximum 3:1 slopes and a 10:1 bench at the NWL. In addition, the proposed ponding is sized to accommodate the drainage generated from the property to the north, as shown in the City's Surface Water Management Plan (SWMP). Drainage calculations for the site have been submitted and only minor changes remain. The applicant is required to meet the existing site runoff rates for the 10 -year and 100 -year, 24-hour storm events. Storm sewer sizing calculations have also been submitted. The storm sewer must be sized for a 10 -year, 24-hour storm event. Drainage and utility easements have been dedicated on the final plat over the public storm drainage system including ponds, drainage swales, and wetlands up to the 100 -year flood level. Proposed erosion control must be developed in accordance with the City's Best Management Practice Handbook (BMPH). Staff recommends that Type II silt fence, which is a heavy duty fence, be used adjacent to the existing wetland, existing creek area, and around the proposed Final Plat — Pinehurst Addition • Planning Case 04-36 March 14, 2005 Page 4 pond. In addition, tree preservation fencing must be installed at the limits of tree removal. Erosion control blankets are recommended for all of the steep 3:1 slopes with an elevation change of eight feet or more. All disturbed areas, as a result of construction, must be seeded and mulched or sodded immediately after grading to minimize erosion. The applicant should be aware that any off-site grading will require an easement from the appropriate property owner. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with detailed haul routes. UTILITIES Municipal sewer and water service is available to the site from Manchester Drive and water service is available from Galpin Boulevard. The water and sewer mains will be extended north from Manchester Drive to serve the site. The watermain will then be looped with the existing 12 -inch diameter main along Galpin Boulevard. In addition, water will be extended to the north property line for future development of the parcel to the north. The water and sewer is also proposed to be extended within the two private streets off of Pinehurst Drive. The watermain in Amberwood Lane is proposed to be connected with the existing watermain from the Brenden Court private street to the west. This watermain connection will provide a "looped" system for the majority of the western side of the site. In order to provide future access to this watermain for maintenance purposes, staff is recommending that the existing bituminous driveway over the watermain off Brenden Court remain. The applicant is also proposing a second gravity sewer line to serve the western two-thirds of the site. This sewer line, which runs from Amberwood Lane to an existing manhole in Lake Lucy Road, is proposed to go south outside of the pavement and right-of-way, through three of the proposed lots and cross over City -owned property prior to connecting to the existing sewer line in Lake Lucy Road. The applicant will directional bore this sewer line in order to minimize the amount of environmental degradation. The installation of this line will alleviate the need for a very deep (40' +) sewer line in Pinehurst Drive. The underlying property has been previously assessed for sewer and water improvements and those assessments have been paid. The sanitary sewer and water hookup charges along with the Lake Ann Interceptor charge will be applicable for each of the new lots. The 2005 trunk hookup charge is $1,458.00 per unit for sanitary sewer and $2,955.00 per unit for watermain. The total 2005 Lake Ann Interceptor charge is $2,270 per unit and the SAC fee is $1,525.00 per unit. All of these charges are based on the number of SAC units assigned by the Metropolitan Council. Sanitary sewer and water -main hookup fees may be specially assessed against the parcel at the time of building permit issuance. All of the utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. Upon completion of the utility improvements, the utilities will be turned over to the City for maintenance and ownership. The applicant is also required to enter into a development contract with the City and supply the necessary financial security in the form of a letter of credit or cash escrow to guarantee installation of the improvements and the conditions of final plat approval. The applicant must be 0 0 Final Plat — Pinehurst Addition Planning Case 04-36 March 14, 2005 Page 5 aware that all public utility improvements will require a pre -con meeting before building permit issuance. Permits from the appropriate regulatory agencies will have to be obtained, including but not limited to the MPGA, Department of Health, and Carver County. STREETS The plans propose two full accesses to the site; one off of Galpin Boulevard from the east side and the other from the extension of Manchester Drive to the south. Additionally, Hemlock Lane will be extended to the north property line to allow for a future street connection with Crestview Drive when the property to the north is developed. A temporary cul-de-sac turnaround for emergency vehicles will be required at the north end of Hemlock Lane along with a sign stating that the road will be extended in the future. All of the proposed public streets comply with the minimum required right-of-way and pavement widths. The applicant is proposing two private streets off of Pinehurst Drive. The private streets are each shown with a 20 -foot pavement width, per City code. In addition, the private street must be built to a 7 -ton design and enclosed within a 30 -foot private easement. The developer will be required to submit inspection/testing reports from an independent geotechnical firm that the street is built to a 7 -ton design. As with past developments that access off of Galpin, a right -turn lane into the site is required to be constructed. During the preliminary plat approval process, concerns were raised about the proposed design length of the turn lane. The tum lane is designed so that it will not conflict with an existing driveway to the north. City staff, the applicant's traffic engineer, and Carver County have all reviewed the design and believe the turn length is sufficient. Based on the fact that 43 lots could potentially access the site from the Pinehurst Drive entrance on Galpin, this translates into approximately 430 total vehicle trips/day (assuming 10 trips/day/lot). In the P.M. peak hour when the turn lane would be most heavily used, Pinehurst Drive could be expected to serve approximately 50 trips divided as follows: approximately 30 trips entering the site and approximately 20 trips exiting the site. Given the proximity of the site to TH 5, it could be reasonably assumed that the majority of trips will be destined to from TH 5 (i.e., to/from the south). Therefore, the right tum lane from Galpin into the site will serve a small amount of the site entering trips. Assuming, conservatively, that 25% of the site traffic will come to/from the north, this translates into P.M. peak hour traffic of 8 trips into the site from the right tum lane. In other words, it can be expected that on average, a vehicle will be using the right turn lane about every 7 to 8 minutes. Given the very low expected southbound right tum volume from Galpin and the fact that the right turn from a dedicated tum lane will be an unimpeded movement, staff concurs with the adequacy of the 94 -foot turn lane as designed. 0 0 Final Plat - Pinehurst Addition Planning Case 04-36 March 14, 2005 Page 6 COMPLIANCE TABLE Area (square feet) Frontage (feet) Depth (feet) Setback (feet) Code 15,000 90, 100 on private street 125 Front - 30, side -10, rear - 30, wetland buffer - 40 Lot 1, Block 1 18,413 110 135 30, 10, 30, na Lot 2, Block 1 16,486 101 132 30, 10, 30, na Lot 3, Block 1 123,324 106 189 30, 10, na, na Lot 4, Block 1 19,249 176 165 30, 10, 30, na Lot 5, Block 1 17,355 123 189 30, 10, 30, na Lot 6, Block 1 16,189 122 168 30, 10, 30, na Lot 7, Block 1 20,221 56 @ 139 30,10, 30, na Lot 8, Block 1 15,996 49 @ 145 30,10, 30, na Lot 9, Block 1 29,879 123 358 30, 10, 30, 40 Lot 10, Block 1 37,037 100 380 30, 10, 30, na Lot 11, Block 1 25,240 69 @ 296 30, 10, 30, na Lot 12, Block 1 20,487 95 226 30, 10, 30, na Lot 13, Block 1 19,574 111 205 30, 10, 30, na Lot 14, Block 1 31,944 209 178 30, 10, 30, 40 Lot 15, Block 1 29,489 137 198 30, 10, 30, 40 Lot 16, Block 1 27,576 83 # 219 30, 10, 30, na Lot 17, Block 1 24,030 103 172 30, 10, 30, na Lot 18, Block 1 23,009 80 @ 210 30, 10, 30, na Lot 19, Block 1 18,446 80 @ 176 30, 10, 30, na Lot 20, Block 1 19,290 80 @ 169 30, 10, 30, na Lot 21, Block 1 15,361 81 @ 150 30, 10, 30, na Lot 22, Block 1 15,935 106 137 30, 10, 30, na Lot 23, Block 1 15,452 131 139 30, 10, 30, na Lot 24 Block 1 15,743 134 152 30, 10, 30, na Lot 25, Block 1 15,850 110 165 30, 10, 30, na Lot 26, Block 1 17,649 139 165 30, 10, na, na Lot 27, Block 1 18,323 182 182 30, 10, 30, na Lot 1, Block 2 18,008 156 176 30, 10, 30, na Lot 2, Block 2 18,292 118 131 30, 10, na, na Lot 3, Block 2 16,393 88 @ 158 30, 10, 30, na Lot 4, Block 2 16,163 106 142 30, 10, 30, na Lot 5, Block 2 15,972 112 143 30, 10, 30, na Lot 6, Block 2 16,019 112 143 30, 10, 30, na Lot 7, Block 2 15,992 112 143 30, 10, 30, na Lot 8, Block 2 17,246 123 139 30, 10, na, na Lot 1, Block 3 26,181 128 175 30, 10, na, na Lot 2, Block 3 17,049 130 130 30, 10, na, na 0 0 Final Plat - Pinehurst Addition Planning Case 04-36 March 14, 2005 Page 7 # Meets 100 foot width at the building setback. @ Meets 90 foot width at the building setback.

LOCATION: 6620 & 6640 Galpin Boulevard Lots 1 & 2, Old Slocum Tree Farm 6 APPLICANT: Plowshares Development, LLC 1851 Lake Drive West, Suite 550 Chanhassen, MN 55317 (952)361-0832 PRESENT ZONING: Rural Residential (RR) 2020 LAND USE PLAN: Residential — Low Density (Net Density Range 1.2 — 4.0 units per acre) ACREAGE: 27.62 DENSITY: 1.52 units/acre gross; 1.85 units/acre net SUMMARY OF REQUEST: The applicant is requesting a rezoning from Rural Residential to Single - Family Residential to permit a 43 -lot subdivision. As part of the subdivision request, the applicant is requesting variances for private streets. LEVEL OF CITY DISCRETION IN DECISION-MAKING: The City has a relatively high level of discretion in approving rezonings because the City is acting in its legislative or policy making capacity. A rezoning must be consistent with the City's Comprehensive Plan. The City's discretion in approving or denying a preliminary plat is limited to whether or not the proposed plat meets the standards outlined in the Subdivision Regulations and Zoning Ordinance. If it meets these standards, the City must approve the preliminary plat. This is a quasi-judicial decision. The City's discretion in approving or denying a variance is limited to whether or not the proposed project meets the standards in the Subdivision Regulations for a variance. The City has a relatively high level of discretion with a variance because the applicant is seeking a deviation from established standards. This is a quasi-judicial decision. Pinehurst Rezoning & Subdivi* with Variances • Planning Case No. 04-36 December 7, 2004 Page 2 PROPOSAUSUMMARY The developer is proposing a 43 -lot single-family residential subdivision. As part of the subdivision, the applicant is requesting the use of two private streets at the western end of the development. These private streets permit the developer to preserve significant areas of woodland. The use of the private street meets the requirements of the subdivision ordinance for approving private streets. The developer had previously submitted a subdivision proposal that included variances from the city's street standards as well as front yard setback variances. However, staff worked with the developer to get a plan that complied with city code requirements and provided lot sizes that accommodate most of the housing plans being proposed. In meeting city requirements, additional tree removal occurs. The plan being reviewed complies with the zoning ordinance requirements. The property is currently zoned Rural Residential, but is guided by the comprehensive plan for Residential — Low Density development. The proposed rezoning of the property to Single Family Residential District, RSF, is consistent with the land use designation and is the same zoning as the surrounding residential developments. The site is located north of the Woodridge Heights development, a 46 -unit single-family development (net density 1.67 units per acre), and east of Brenden Pond, a 21 -unit single family development (net density 1.68 units per acre). To the north are Minnetonka West Junior High and an older neighborhood The north - south street is being extended to the northerly property and will be extended with the development of the Shively Addition, which has the potential for subdivision into five lots, providing a connection to Crestwood Drive. Water and sewer service were extended to the southerly property tine with the development of Woodridge Heights. This proposed development will extend water and sewer service to the northerly property line as well as looping the water back to Galpin Boulevard. A trail is located on the west side of Galpin Boulevard. Sidewalks will be included on all the public streets within the development. The site's high point with an elevation of 1070 is located in the north -central portion of the property. From there, it falls east to an elevation of 1034, south to an elevation of 1020 and west to an elevation of 1020. There is a drainage ravine and wetlands located in the western portion of the site. The site consists of significant areas of woodlands located primarily on the western portion of the property. Rows of pines run north -south delineating the western 530 feet of the property and along the northern and eastern property lines. Other areas of trees are scattered over the easterly 1300 feet of the property. Staff is recommending approval of the development subject to the conditions of approval. The easterly 13.5 acres of the property was subdivided into two lots as part of the Old Slocum Tree Farm Addition on April 6, 1987, with lot areas of 4 and 9.5 acres. The rear 14.12 acres were required to be attached to Lot 2, Block 1, Old Slocum Tree Farm as a condition of the plat approval. At that time, the property was zoned R1 a, Agricultural residence. Pinehurst Rezoning & Subdivilewith Variances • Planning Case No. 04-36 December 7, 2004 Page 3 The applicant is proposing the rezoning of the property from Rural Residential, RR, to Single -Family Residential, RSF. The RSF zoning is consistent with the City's Comprehensive Plan, which guides the property for Residential — Low Density use with a net density range of 1.2 to 4.0 units per acre. The proposed subdivision is at a net density of 1.85 units per acre. The RR district requires a minimum lot size of 2.5 acres. Development using the RR zoning would be inconsistent with the comprehensive plan. SUBDIVISION REVIEW WETLANDS Existing Wetlands Three ag/urban wetlands exist on-site. Wetlands were delineated by Westwood Professional Services on July 15, 2004. The total area of wetlands is 0.14 acres (6,098 square feet). Wetland A located within the southwest comer of the property has been classified as a riverine, intermittent streambed with a mud bottom. The wetland is dominated by garlic mustard, ostrich fern and Jack-in-the-pulpit. No impacts to Wetland A are proposed. Wetland B located in the south-central portion of the property is classified as a Type 1 wetland. The wetland vegetation is dominated by box elder. No impacts to Wetland B are proposed. Wetland C located in the northwestern comer of the property is classified as a Type 1 wetland. The wetland's vegetation is dominated by box elder and Canada clearweed. No impacts to Wetland C are proposed. Wetland buffer widths of 16.5 feet to 20.0 feet must be maintained around all wetlands on-site. All structures must maintain a 40 -foot setback from wetland buffer edges. The building pad on Lot 9, Block 1 should be revised to reflect the wetland setback requirements. Wetland buffer areas should be preserved, surveyed and staked in accordance with the City's wetland ordinance. The applicant must install wetland buffer edge signs, under the direction of City staff, before construction begins and must pay the City $20 per sign. GRADING, DRAINAGE AND EROSION CONTROL The existing site is about 27 acres and has tree cover over approximately 18 acres (65% of the parcel). The existing parcel has a wide variety of grade changes within its limits. The site elevations range from a high of 1070± to a low of 1006±. These severe elevation differences make this site a challenging one to both develop and minimize grading. The plans propose to grade about 75-80% of the site for the 43 new house pads, a proposed street system, three cul-de-sacs and a stormwater pond. The proposed grading will prepare the site for full basement, look -out and walk -out type house pads. Retaining walls are proposed in numerous locations throughout the site. The applicant must be aware that any retaining wall over four feet in height must be designed by a registered civil engineer and a permit from the City Building Department must be obtained. In addition, encroachment agreements will be required for any retaining wall within a public easement. Pinehurst Rezoning & Subdiviis with Variances • Planning Case No. 04-36 December 7, 2004 Page 4 Staff does have a couple areas of concern in regards to the grading. The proposed house pad on Lot 27, Block 1 has steep slopes draining to or away from it on three out of the four sides. In staffs opinion, this grading design makes the lot undesirable at best. Also, there are two retaining walls just south of the lot which are adjacent to the proposed pond. If Lot 27 were eliminated, the pond could be shifted to the north which would eliminate the need for the southerly portions of the retaining walls. Because of the above reasons, staff is recommending that Lot 27, Block 1 be eliminated. In addition, it appears that a large portion of the western end of the site is being filled. This filling requires the use of five retaining walls on the western end of the site. Staff would recommend that the applicant lower the western end of the site in the area of the two private drives. This will help to minimize the overall amount of grading in the area, decrease the size of the retaining walls, and better match the existing topography of the area. The existing site drainage is encompassed within two different drainage areas. Under existing conditions, the western part of the site drains off site to an existing wetland to the west; the eastern part of the site drains off site to the south. Under developed conditions, the applicant is proposing to capture all of the street drainage, all of the front yard drainage and some rear yard drainage from the interior lots. This stormwater will be conveyed via storm sewer to a proposed pond in the south center of the site for treatment. The proposed pond must be designed to National Urban Runoff Program (NURP) standards with maximum 3:1 slopes and a 10:1 bench at the NWL. In addition, the proposed ponding must be sized to accommodate the drainage generated from the property to the north, as shown in the City's Surface Water Management Plan (SWMP). Drainage calculations for the site have been submitted and some changes remain. The applicant is required to meet the existing site runoff rates for 10 -year and 100 -year, 24-hour storm events. Storm sewer sizing calculations must be submitted at the time of final plat application. The storm sewer must be sized for a 10 -year, 24 -how storm event. Drainage and utility easements must be dedicated on the final plat over the public storm drainage system including ponds, drainage swales, and wetlands up to the 100 -year flood level. Proposed erosion control must be developed in accordance with the City's Best Management Practice Handbook (BMPH). Staff recommends that Type II silt fence, which is a heavy duty fence, be used adjacent to the existing wetland, existing creek area, and around the proposed pond. In addition, tree preservation fencing must be installed at the limits of tree removal. Erosion control blankets are recommended for all of the steep 3:1 slopes with an elevation change of eight feet or more. All disturbed areas, as a result of construction, must be seeded and mulched or sodded immediately after grading to minimize erosion. The applicant should be aware that any off-site grading will require an easement from the appropriate property owner. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with detailed haul routes. Storm Water Management The proposed development is required to maintain the existing runoff rates. Preliminary storm water calculations submitted with the plans illustrate that storm water ponds located on Outlot B have been properly sized to handle post -development 2, 10 and 100 -year storm events for the site. However, the City's Surface Water Management Plan shows that a regional pond should be constructed to Pinehurst Rezoning & SubdiviJO with Variances • Planning Case No. 04-36 December 7, 2004 Page 5 accommodate storm water runoff from the Shively Addition. Pond A should be expanded to the northeast to accommodate future development of this site. Final storm water calculations should be submitted to ensure the appropriate drainage areas are captured and that proposed storm water ponds meet all requirements. Detailed plans for proposed storm water infrastructure (including catch basins and outlet structures) should be submitted. Erosion Control Erosion control blanket should be installed on all slopes greater than or equal to 3:1. All exposed soil areas should have temporary erosion protection or permanent cover year round, according to the following table of slopes and time frames: Type of Slope Time (maximum time an area can remain unvegetated when area is not active) be' worked) Steeper than 3:1 7 Days 10:1 to 3:1 14 Days Flatter than 10:1 21 Days These areas include constructed storm water management pond side slopes, any exposed soil areas with a positive slope to a storm water conveyance system, such as a curb and gutter system, storm sewer inlet, temporary or permanent drainage ditch or other man-made systems that discharge to a surface water. Daily scraping and sweeping of public streets should be completed any time construction site soil, mud, silt or rock is tracked or washed onto a paved surface or street that would allow tracked materials or residuals of that material to enter the storm water conveyance system. Construction site access points should be minimized to controlled access points with rock entrance and exit pads installed and maintained throughout construction. SURFACE WATER MANAGEMENT FEES Water Quality Fees Because of the impervious surface associated with this development, the water quality fees for this proposed development are based on single-family residential development rates of $1,028/acre. Based on the proposed developed area of 23.36 acres, the water quality fees associated with this project are estimated to be $24,014. Water Quantity Fees The SWMP has established a connection charge for the different land uses based on an average city wide rate for the installation of water quantity systems. This cost includes land acquisition, proposed SWM? culverts, open channels, and storm water ponding areas for runoff storage. Single-family residential developments have a connection charge of $2,545 per developable acre. This results in a water quantity fee of approximately $59,451 for the proposed development. Pinehurst Rezoning & Subdivilowith Variances • Planning Case No. 04-36 December 7, 2004 Page 6 SW -W Credits This project proposes the construction of one NURP pond. The applicant will be credited for water quality where NURP basins are provided to treat runoff from off-site. This will be determined upon review of the ponding and storm sewer calculations. Credits may also be applied to the applicant's SWMP fees for the provision of outlet structures. No credit will be given for temporary pond areas. Based on the proposed developed area of 23.36 acres, the estimated total SWMP fee, due payable to the City at the time of final plat recording, is $83,465. OTHER AGENCIES The applicant must apply for and obtain permits from the appropriate regulatory agencies (e.g., Riley - Purgatory -Bluff -Creek Watershed District, Minnesota Pollution Control Agency (NPDES Phase H Construction Permit), Minnesota Department of Natural Resources (for dewatering)) and comply with their conditions of approval. UTILITIES Municipal sewer and water service is available to the site from Manchester Drive and water service is available from Galpin Boulevard. The water and sewer mains will be extended north from Manchester Drive to serve the site. The watermain will then be looped with the existing 12 -inch diameter main along Galpin Boulevard. In addition, water will be extended to the north property line for future development of the parcel to the north. The water and sewer is also proposed to be extended within two private streets (D and E) off of Street A. The watermain in Private Drive D is proposed to be connected with the existing watermain from the Brenden Court private street to the west. This watermain extension can be directionally bored which will preserve the existing trees within the western side of the site. The watermain connection will provide a "looped" system for the majority of the western side of the site. The applicant is also proposing a second gravity sewer line to serve the western two-thirds of the site. This sewer line, which runs from MH -18 to an existing manhole in Lake Lucy Road, is proposed to go south outside of the pavement and right-of-way, through Lot 17, Block 1 and cross over City -owned property prior to connecting to the existing sewer line in Lake Lucy Road. Staff is recommending that this western sewer line be eliminated for the following reasons. First, the City -owned land that the sewer would run through is very steep. City staff has concerns with access and maintenance of such a line on a steep slope. Second, the City -owned property was originally acquired as a possible future well site. The location of the sewer line on the property could limit the possible well locations. Finally, the existing sanitary line in Manchester Drive was stubbed to this property to serve the entire site. City Code requires a minimum 30 -foot wide public easement over the public sewer and watermain within private streets. Due to the depth of the proposed sanitary sewer from MH -20 to MH -17, however, the required easement width will need to be increased to 50 feet. The underlying property has been previously assessed for sewer and water improvements and those assessments have been paid. The sanitary sewer and water hookup charges along with the Lake Ann Interceptor charge will be applicable for each of the new lots. The 2004 trunk hookup charge is $1,458.00 per unit for sanitary sewer and $2,814.00 per unit for watermain. The total 2004 Lake Ann Pinehurst Rezoning & Subdivie with Variances • Planning Case No. 04-36 December 7, 2004 Page 7 Interceptor charge is $2,102 per unit and the SAC fee is $1,425.00 per unit. All of these charges are based on the number of SAC units assigned by the Metropolitan Council. Sanitary sewer and water - main hookup fees may be specially assessed against the parcel at the time of building permit issuance. All of the utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. Upon completion of the utility improvements, the utilities will be turned over to the City for maintenance and ownership. The applicant is also required to enter into a development contract with the City and supply the necessary financial security in the form of a letter of credit or cash escrow to guarantee installation of the improvements and the conditions of final plat approval. The applicant must be aware that all public utility improvements will require a pre -con meeting before building permit issuance. Permits from the appropriate regulatory agencies will have to be obtained, including but not limited to the MPCA, Department of Health, and Carver County. STREETS The plans propose two full accesses to the site; one off of Galpin Boulevard from the east side and the other from the extension of Manchester Drive to the south. Additionally, Street B will be extended to the north property line to allow for a future street connection with Crestview Drive when the property to the north is developed. A temporary cul-de-sac turnaround for emergency vehicles will be required at the north end of Street B along with a sign stating that the road will be extended in the future. All of the proposed public streets comply with the minimum required right-of-way and pavement widths. For Street C, the applicant is proposing a very wide right-of-way with a large island in the center. Due to maintenance concerns with such a large right-of-way, staff is recommending that Street C be revised to be a standard cul-de-sac. Also, Galpin Boulevard is designated as an arterial road in the city. Per City Code, arterial roads are required to have 100 feet of total right-of-way or 50 feet from each side of the centerline of the road. As such, this development is required to provide enough additional platted right-of-way which results in 50 feet of right-of-way on the western side of the Galpin Boulevard centerline. As with past developments that access off of Galpin, a right -turn lane into the site will be required to be constructed. The turn -lane must meet Carver County design requirements. LANDSCAPING/TREE PRESERVATION Tree canopy calculations have been submitted for the Pinehurst development. They are as follows: Total upland area (excluding wetlands) 27.48 ac. Baseline canopy coverage 65% or 17.92 ac. Minimum canopy coverage allowed 46% or 12.64 ac. Proposed tree preservation 26% or 7.23 ac. The developer does not meet minimum canopy coverage allowed; therefore, the difference between the baseline and proposed tree preservation is multiplied by 1.2 to calculate the required replacement plantings. Difference in canopy coverage 235,660 SF or 5.41 ac. Multiplier 1.2 Pinehurst Rezoning & Subdivio with Variances • Planning Case No. 04-36 December 7, 2004 Page 8 Total replacement 282,792 SF Total number of trees to be planted 260 trees The applicant has proposed 262 trees in their landscape plan. Bufferyard requirements are as shown in the table: Landscaping Item Required Proposed Bufferyard B* - East 12 overstory trees Existing tree line of white property line 18 bunderstory trees cedars and other Front - 30, side -10, rear - 30, wetland buffer -40 30 shrubs trees/shrubs Applicant meets minimum requirements for bufferyard plantings.
