PHYSICAL CHARACTER.: The highest elevation on the site is 980. The site generally slopes to the north and northeast. A residential single family and a detached accessory structure occupy the site. BluffCreek runs to the north of the subject site. There are scattered woods on the site. 2000 LAND USE PLAN: Residential-Low Density (Net Density Range 1.2 - 4 units per acre) I0 ~,~0¢¢' 00 ¥ o¢ j~O0~ ~, 4 ~ 4 12' Lynmore Addition March 17, 1999 Page 2 PROPOSAL SUMMARY The applicant is requesting approval for a General Concept and Preliminary PUD Development ,Plan to rezone 6.39 acres from A-2, Agricultural Estate District to PUD-R, Planned Unit Development-Residential, preliminary plat approval to subdivide 6.39 acres into 8 single family lots and 2 outlots, and vacation of a portion of a utility and drainage easement located on Lot 9, Block 1, Stone Creek 6th Addition. The average lot size is 17,901 square feet with a resulting net density of 1.44 units per acre. While this density is below the city's goal of 2.42 units per acre, the city is preserving approximately 3.5 acres of the bluff creek primary zone in the eastern portion of the site. The Bluff Creek primary zone represents approximately 2.76 acres of the site. With this land excluded from the density calculations, the net density of the site would be 2.86 units per acre. The site is located east of Galpin Boulevard just north of Stone Creek Addition and west of Stone Creek Park. The site contains clusters of wooded areas, as well as open spaces, and a terrain that generally slopes down to the north. It contains a single family home and a detached accessory structure. Bluff Creek runs approximately 200+ feet north of the subject site. Access to the subdivision will be provided via a cul-de-sac connecting the subdivision with Galpin Boulevard. The eastern two acres of the site is located within the primary zone of the bluff creek overlay district. City ordinance requires that the ~primary zone be reserved for open space. In reviewing this application, staff worked with the applicant and offered some suggestions to .minimize the impact on the natural features of the site. It was explained that the most effective way of developing the site would be to cluster the homes along the western portion of the site and preserve the eastern portion. The resulting plan provides the least impact to the site. With all the natural features, meandering terrain, and close proximity to Bluff Creek, the site is an excellent candidate for a Planned Unit Development. The intent of a PUD is to develop flexible zoning while creating a higher standard of development. Part of the PUD process is to establish development standards by which the development will be required to adhere to. This PUD will be -governed by the final development plan. The proposal consists of a general concept and preliminary development plan for rezoning from A-2 to PUD-R (the PUD ordinance states that if appropriate because of the limited scale of the proposal, the concept stage and preliminary plan stages may proceed simultaneously). The overall preliminary PUD appears to be in order and well designed. The intended use of the site is to provide building sites for single family homes. The development is consistent with all plans and ordinances; it preserves natural conditions to the greatest extent feasible, creates a suitable balance between the amount and arrangement of open space, and provides safe and adequate access and internal circulation. Lynmore Addition March 17, 1999 Page 3 In reviewing this plat, staff also had to look at access to the property to the north. While the property owner (Mr. Schmidt) is not ready to develop or subdivide at this time, we need to ensure that the parcel is not landlocked. Currently, the subject site and the property to the north share a private driveway. With the Lynmore subdivision, the existing house will gain access via Bridal Creek Court. If and when Mr. Schmidt decides to subdivide his property, access should be gained through the Lynmore subdivision. Staff is recommending this access be in the form of a private driveway through Outlot B. Through rough sketches and field surveys, we believe that Mr. Schmidt could potentially get 3 additional lots. The private driveway ordinance allows a maximum of 4 lots to be served via a private driveway and this parcel meets the criteria for private driveways. Outlot B, Lynmore Addition, could still be replatted into a buildable lot, if it were combined with a portion of Mr. Schmidt's property and the exiting driveway serving Mr. Schmidt's home were eliminated. The subdivisions request is straight forward. The PUD Ordinance allow a minimum lot size of 11,000 square feet with an average lot size of 15,000 square feet for the entire PUD. All parcels exceed the minimum area requirements with an average lot size of 17,901 square feet excluding the area ofOutlots A and B. The PUD allows for a reduced front yard setback if environmental protection is enhanced. The applicant is requesting the use of 25 foot front setback for the development. In this case, the reduced setback will allow for protection of vegetation within rear yards and reduce grading. The westerly 95 feet of the site is actually part of Lot 9, Block 1, Stone Creek 9th Addition. The applicant has combined that part of Lot 9 with the subject site, which is the logical thing to do. There is an existing drainage and utility easement that runs along the exterior lot lines of Lot 9. The applicant is requesting to vacate the easements portion that are part of the current subdivision and dedicate new easements that run along the interior lot lines of Lot 1, Block 1, Lynmore Addition. Staff is recommending approval of the vacation. Staff believes the proposal, combined with conditions proposed by staff, will be effective in providing enhanced environmental sensitivity beyond normal ordinance requirements. In retum the developer gains reduced lot sizes, flexibility in development standards such as setbacks, street width, and reduced development improvement costs. Staff finds the proposed PUD, plat and utility and drainage easement vacation be acceptable and is recommending approval of the general concept and preliminary stage of the PUD plan, preliminary plat, and vacation subject to proposed conditions. Lynmore Addition March 17, 1999 Page 4 REZONING Justification for Rezoning to PUD The applicant is requesting to rezone 6.39 acres from A-2, Agricultural Estate District to PUD-R, Planned Unit Development-Residential. The following review constitutes an evaluation of the PUD request. The review criteria is taken from the intent section of the PUD Ordinance. Section 20-501. Intent Planned unit developments offer enhanced flexibility to develop a site through the relaxation of most normal zoning district standards. The use of the PUD zoning also allows for a greater variety of uses, intemal transfer of density, construction phasing and a potential for lower development costs. In exchange for this enhanced flexibility, the city has the expectation that the development plan will result in a significantly higher quality and more sensitive proposal than would have been the case with the other, more standard zoning districts. It will be the applicant's responsibility to .demonstrate that the City's expectations are to be realized as evaluated against the following criteria: Planned unit developments are to encourage the following: Preservation of desirable site characteristics and open space and Protection of sensitive environmental features, including steep slopes, mature trees, creeks, wetlands, lakes and scenic views. Finding. The majority of the site will remain intact since the applicant will be clustering the development along the western portion of the property. o More efficient and effective use of land, open space and public facilities through mixing of land uses and assembly and development of land in larger parcels. Finding. The site is surrounded by environmentally sensitive features. Clustering the homes to the west and leaving the easterly portion undisturbed will result in an efficient and effective use of land and open space. The applicant has offered to dedicate the westerly half of the property (Outlot A) to the City to be combined with Stone Creek Park. o High quality design and design compatibility with surrounding land uses, including both existing and planned. Site planning, landscaping and building architecture should reflect higher quality design than is found elsewhere in the community. Lynmore Addition March 17, 1999 Page 5 Finding. The proposed development is compatible with surrounded uses. Through the incorporation of the recommendations contained in this report, staff believes that the project will reflect higher quality design. Sensitive development in transitional areas located between different land uses and along significant corridors within the city will be encouraged. Finding. The proposed design is compatible with surrounding area and reflects a sensitive development. The dedication ofOutlot A as a park will leave this area undisturbed providing a buffer as well as a transition area between surrounding properties. 5. Development which is consistent with the Comprehensive Plan. Finding. The Comprehensive Plan guides this area for Residential Low Density and the development is consistent with the comprehensive plan. The comprehensive plan also highly encourages the preservation of environmentally sensitive features such as wooded areas, steep slopes and waterways. This plan provides preservation of all these features. Parks and open space. The creation of public open space may be required by the city. Such park and open space shall be consistent with the Comprehensive Park Plan and overall trail plan. Finding. The applicant is preserving the Bluff Creek corridor. 7. Provision of housing affordable to all income groups if appropriate with the PUD. Finding. Not applicable to this proposal. Energy conservation through the use of more efficient building designs and sightings and the clustering of buildings and land uses, Finding. The proposed mix of housing types provides energy conservation through the efficiencies related to site development. Use of traffic management and design techniques to reduce the potential for traffic conflicts. Improvements to area roads and intersections may be required as appropriate. Finding. Access to this site will be from Galpin Road. There is a private drive that is currently being shared by the subject site and the property to the north. Eventually this driveway will be eliminated when the property to the north develops. Lynmore Addition March 17, 1999 Page 6 Summary of Rezoning to PUD Rezoning the property to PUD provides the applicant with flexibility, but allows the city to request additional improvements and the site's unique features can be better protected. The flexibility in standards allows the disturbed areas to be further removed from the unique features of the site. In return for the flexibility, the city is receiving: Development that is consistent with Comprehensive Plan Preservation of desirable site characteristics (trees, waterways, topographical features) Sensitive development in transitional areas More efficient use of land High quality project design PRELIMINARY STAGE PUD PLAN APPROVAL Development Standards The applicant is requesting approval for General Concept and preliminary PUD Development Plan to rezone 6.39 acres from A-2, Agricultural Estate District to PUD-R, Planned Unit Development- Residential. The purpose of this request is to subdivide 6.39 acres into 8 single family lots and 2 outlots. The density of the proposed subdivision is 1.25 units per acre gross. All the lots exceed the minimum 11,000 square feet of area, except lot 8, and an average lot size of 15,000 square feet, with an average lot size of 17,901 square feet. The site is located east of Galpin Boulevard just north of Stone Creek Addition and west of Stone Creek Park. The site contains clusters of wooded areas, as well as open spaces, and a terrain that generally slopes down to the north. It contains a single family home and a detached accessory structure. Bluff Creek runs approximately 200 + feet north of the subject site. Access to the subdivision will be provided via a cul-de-sac connecting the subdivision with Galpin Boulevard. All of the proposed lots meet the minimum depth requirements of the PUD Ordinance. The lots on the south side of the project do not meet the minimum width requirement. However, staff supports the deviation from the standards since the developer will be preserving the eastern portion of the site as permanent open space. There are two outlots shown on the plat. Outlot A will remain undisturbed and will be dedicated as park land and combined with Stone Creek Park. Outlot B is reserved for future development. The property to the north owns a portion of this outlot and unless they are combined, the parcel can not be developed. Staff is recommending that 30 feet of Outlot B be dedicated for a private driveway purposes to provide access to the property to the north. This issue will be discussed in more detail under "STREETS" later in the report. Lymnore Addition March 17, 1999 Page 7 The PUD ordinance requires all structures to maintain a 30 foot front and mar yard setback and a 10 foot side yard setback. The ordinance also states that The thirty foot front yard setback may be waived by the city council when it is demonstrated that environmental protection will be enhanced. In these instances, a minimum front yard setback of twenty (20)feet shall be maintained. Staff encouraged the applicant to use the 25 foot front yard setback to maximize the buildable area of the lots. The dedication of Outlot A as park land is a demonstration that environmental protection is being provided. This Outlot is located within the primary zone of Bluff Creek and it will provide protection of the creek. This is a compromise that benefits both the developer and the city. Them is an existing detached structure located on proposed Lot 7. This structure will create a non- conforming situation since the ordinance does not allow accessory structures without the construction of a primary structure. Therefore, the detached accessory structure must be removed prior to recording of the plat. Staff notes that the proposal is consistent with the Comprehensive Plan and generally consistent with the Zoning Ordinance. WETLANDS There are no wetlands on site. SURFACE WATER MANAGEMENT PLAN (SWMP) Storm Water Quality Fees The SWMP has established a water quality connection charge for each new subdivision based on land use. Dedication shall be equal to the cost of land and pond volume needed for treatment of the phosphorus load leaving the site. The requirement for cash in lieu of land and pond construction shall be based upon a schedule in accordance with the prescribed land use zoning. Values are calculated using market values of land in the City of Chanhassen plus a value of $2.50 per cubic yard for excavation of the pond. The city has had discussions with the applicant's engineer on the water quality ponding. The proposed SWMP water quality charge of $800/acre, (or $3,400 for the 4.25 acres) for single-family residential developments may be waived if the applicant provides water quality treatment according to the city's SWMP standards. To date this development plan has no on site treatment pond. Storm 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, Lynmore Addition March 17, 1999 Page 8 proposed SWMP culverts, open channels and storm water ponding areas for runoff storage. Single family residential developments will have a connection charge of $1,980 per developable acre. The total gross area of the property is 4.25 acres. Therefore, the proposed development would then be responsible for 4.25 acres resulting in a water quantity connection charge of $8,415. This fee will be due payable to the city at time of final plat recording. PARK AND TRAIL The Park and Recreation Commission reviewed the Lynmore Subdivision on February 23, 1999. Their review was prior to the plan being revised to identify Outlot A as open space. As such, the commission recommended denial of the application for failing to meet the open space preservation requirements of the Bluff Creek ordinance. The Park and Recreation Commission was very clear that without the preservation of the primary zone, they would not support this application. The Park and Recreation Commission will be pleased to see the revised plans. On March 23, I will present the new set of plans to the commission. It will be my recommendation that the commission offer the applicant full park fee credit, $8,400, in exchange for fee title ownership of Outlot A. This trade off is not required to ensure the outlot remain open space. The land is already protected by the Bluff Creek ordinance. The credit is offered as an inducement to the applicant to transfer fee title to the city. In this particular situation, fee title is desirable as the outlot abuts Stone Creek Park. LANDSCAPING Tree canopy coverage and preservation calculations Total upland area (including outlots) Total canopy area (excluding wetlands) Baseline canopy coverage Minimum canopy coverage allowed Proposed tree preservation for the Lynmore development are as follows: 278,348 SF or 6.39 ac. 130,680 SF or 3.0 ac. 47% 35% or 97,422 SF 38% or 105,313 SF Developer meets minimum canopy coverage allowed. One tree shall be planted in each from yard per city ordinance. Applicant is proposing to transplant 21 trees ranging in size from 3-9 inches in diameter. The variety of trees include 7 ash, 12 maple, 1 apple and 1 cherry. These trees could be counted as replacement plantings provided they are guaranteed for at least one year. Lynmore Addition March 17, 1999 Page 9 Bufferyard plantings will be required along the approximately 280' of frontage of Galpin Boulevard. Assuming a 20' bufferyard, minimum requirements include 5 overstory trees, 7 understory trees and 11 shrubs. The applicant shall revegetate the area around the proposed storm water pond with a native seed mixture approved by the city. The applicant may refer to MNDOT seeding manual mixture 50 for an acceptable seed mix. BUILDING DEPARTMENT ISSUES Dwelling Types, The type of dwelling proposed for each lot is necessary to enable the Inspections Division and Engineering Department to perform a satisfactory plan review of the structure at the time of building permit issuance. For the same reason, proposed lowest level floor elevation, entry floor elevation (not top of block) and garage floor elevation is required to be indicated on the proposed pad location. Standard designations (FLO or RLO, R, SE, SEWO, TU, WO) must be shown for proposed dwelling types. These standard designations lessen the chance for errors during the plan review process. The memo explaining these designations is enclosed. Demolition Permits. Existing structures on the property which will be demolished will require a demolition permit. Proof of well abandonment must be furnished to the city and a permit for septic system abandonment must be obtained and the septic system abandoned prior to issuance ora demolition permit. A house moving permit is required ifa structure is to be moved to another location within the city. House moving permits must be approved by the City Council. A road use permit is required to move a structure over city roads. GRADING The easterly half the site is proposed to be graded to prepare the house pads and street subgrade. Outlot A is proposed to remain undisturbed. A storm water pond is proposed on Lot 5. Upon preliminary review the pond configuration may change to limit tree loss and minimize grading. Utility extension from the north along Galpin Boulevard will also require grading a 30-foot wide pathway along Galpin Boulevard through Outlot B. The quantity of earthwork is unknown at this time; however, the applicant should be advised if exporting or importing of material is necessary, a detailed haul route and traffic control plan will be required prior to site grading commencing. In addition, if material is being exported or imported from another Chanhassen site, that property will also be required to obtain the necessary earthwork permits in accordance with city ordinance. The existing home utilizes a well and septic system. The well and septic system is not located on the grading plan and therefore it is difficult to determine whether the site grading will impact Lynmore Addition March 17, 1999 Page 10 either of the utilities. The well and septic site needs to be preserved on the site until municipal city sewer and water have been extended along Bridle Creek Court and tested and accepted by the city. The final grading plan shall denote the existing lowest floor, first floor and garage elevations of the home on Lot 6. The cul-de-sac grade may need to be lowered one to two feet to accommodate drainage from Lot 6 out to the street. In addition, the street grade and/or house pad elevations on Lots 7 and 8 need to be adjusted to provide a minimum of 1.5 feet of fall from the first floor and garage floor elevations out to the street. DRAINAGE The majority of the site sheet drains north, east and south. The proposed grading will maintain the pre-developed drainage pattern in the area for the most part. Grades along the south property need to be adjusted to keep runoff from the site from discharging onto the Stone Creek development south of this proposal. The resulting drainage area to the south and east of the property will be reduced after construction. The plans propose to drain the street and front yard areas of the lots into a storm sewer system which will convey the runoff into a storm pond on Lot 5 for pretreatment before discharging into Bluff Creek. The location and design of the storm pond may be altered after further review by staff. There is an existing drainage swale that drains along the common property line of Stone Creek Development and this proposal. The surface water drains along the property line into the existing ravine through Lots 4 and 5 down to Bluff Creek. The proposed house pad on Lot 4 could experience wet areas on both sides of the house due to drainage through the area. These drainage constraints should be considered and resolved in conjunction with the design of the home for Lot 4. A drainage easement shall be dedicated on the final plat to preserve the drainageway/ravine and pond through Lot 4. The minimum width shall be 20 feet wide. The construction plans will have to incorporate a drain tile system behind the curbs to address household sump pump discharge for those lots not adjacent to a storm water pond or wetland. Drain tile is also beneficial in absorbing subgrade moisture from the street. UTILITIES Municipal utility service is indirectly available to the site. Water service is available along Galpin Boulevard. Sanitary sewer service has been a point of discussion in the past. The sewer line to service this site is located approximately 750 feet north of the site near Lukewood Drive. Extension of this sanitary sewer would be very difficult given the terrain and vegetation. In addition, the applicant would have to obtain permanent and temporary easements from the adjacent property owner (Schmidt) to extend the utilities to service this development. The developer has attempted to acquire easements from the Schmidt's, however, to no avail. Another alternative for sanitary sewer service has been proposed from the west side of Galpin Boulevard. This design appears feasible and will ultimately service the parcel to the north (Schmidt) as well. Lynmore Addition March 17, 1999 Page 11 This sewer proposal, however, will not serve Outlot A without a lift station. Outlot A will not have gravity sewer service and should be considered non-buildable. Temporary construction easements and a county permit will be involved in pursuing this alternative sewer proposal. The developer shall be responsible to obtain the necessary easements and permits. Should the developer not obtain the necessary easements or permits, the subdivision in question shall be considered premature since sanitary sewer would not then be available to service the development. The utility improvements proposed to service the site shall be designed and constructed in accordance with the city's standard specifications and detail plates. Upon completion of the utility improvements, the utilities will be turned over the city for maintenance and ownership. Detailed utility and street construction plans and specifications in accordance with the city's latest edition of Standard Specifications and Detail Plates will be required in conjunction with final plat consideration. Construction drawings will need to be submitted to staff for review at least three weeks prior to final plat consideration. The construction plans and specifications for the project will be subject to staff review and City Council approval. The developer will be required to enter into a PUD Agreement/Development Contract with the city and provide the necessary financial security to guarantee conditions of approval. The financial security shall be in the form of a letter of credit or cash escrow. The existing house on Lot 6 will be required to hook up to the new sewer water line in Bridle Creek Court within 30 days after the utilities have been accepted by the city. Connection to city water is not necessary unless the well fails on Lot 6. The lots in the plat will also be subject to deferred assessments as a result of the .city's Upper Bluff Creek Trunk Improvement Project No. 91-17B. The parcel was previously assessed for.only one trunk sewer and water assessment. Upon final platting of the property, seven .(one per lot) sewer and water trunk hookup charges shall be pending. The trunk sewer and water charges shall be collected at time of building permit issuance. The 1999 trunk sewer utility hook-up charge is $1,252 per unit and trunk watermain hook-up charge is $1,632 per unit. STREETS Access to the development is proposed from Galpin Boulevard/County Road 19. This road is classified in the city's Comprehensive Plan as a collector street. The minimum right-of-way width of Galpin Boulevard shall be 100 feet wide. The preliminary plat indicates 50 feet of fight- of-way exists adjacent to this development; however, the city, through a previous project, attempted to acquire an additional 17 feet of right-of-way and a 10-foot wide trail and utility easement. Staffdoes not believe that the right-of-way and additional trail and easements were acquired and will need to be dedicated with the final plat. Staff will be further reviewing this and may result in the developer dedicating a total of 17 feet of right-of-way along Galpin Boulevard and a 1 O-foot wide trail, drainage and utility easement. The additional easement dedication does not appear to affect the lot sizes in the preliminary plat submittal. The preliminary plat proposes a 60-foot wide right-of-way with a 60-foot radius for the cul-de- sac in accordance with City Code. The front building setbacks are proposed at 25 feet versus 30 Lymnore Addition March 17, 1999 Page 12 feet. Street grades may have to be adjusted to maintain a 3% landing for the first 75 feet east of Galpin Boulevard and lowering of the cul-de-sac to provide drainage from the lots out to the street. The street grade in the cul-de-sac shall be a minimum of 1% to maintain drainage around the curbs. In an effort to minimize the blacktop area of the cul-de-sac staff recommends the developer consider a landscaped island. This has worked well in past developments. The city, however, shall be responsible for maintenance of the landscaped island. The developer or their assignee such as a homeowner's association would be responsible for maintenance. The site is currently accessed through a shared gravel driveway off of Galpin Boulevard with the Schmidt property to the north. As a result of platting the property a public street (Bridle Creek Court) will be extended to service the development as well as the Schmidt parcel. A 30-foot wide driveway and utility easement is proposed over Outlot B to provide access to Schmidt's. The location of the existing driveway is not desirable from a traffic safety standpoint. Staff has recommended that a future private driveway through Outlot B be reserved to service future subdivision of the Schmidt parcel. The Carver County Public Works Department has the jurisdiction to approve additional access points or modify existing access points along Galpin Boulevard. Staff believes that the Schmidt parcel should access Bridle Creek Court through Outlot B with a private driveway. Staff also believes the Schmidt parcel does not have the capability to subdivide into more than four single-family lots based on current ordinances and topographic features. Outlot B as currently proposed is not a buildable lot. There is a parcel of land that is owned by the Schmidt's that is needed to be acquired to develop Outlot B into a buildable parcel. Staff recommends that a 30-foot wide strip of land be deeded or easement dedicated to the city over Outlot B for future access (private driveway) to the Schmidt parcel to serve up four residential homes. The exact location of this easement can be modified through negotiations with staff and the applicant. Bridle Creek Court is proposed to be constructed to city urban street standards within a 60-foot wide right-of-way. Detailed street construction plans and specifications will be required prior to final plat consideration. The public street shall be constructed in accordance with the city's latest edition of Standard Specifications and Detail Plates. There are city-owned street lights along Galpin Boulevard that may be impacted with the street connection. This must be verified and street lights relocated in accordance with city standards. A street light will also be required at the end of the cul-de-sac. The developer shall also coordinate with the appropriate utility companies for the installation of small utilities, i.e. NSP, Minnesota Valley Electric, Minnegasco, Triax Cable and U.S. West. Access to the existing house on Lot 6 must be maintained during construction from both a public safety standpoint and a resident standpoint. Once Bridle Creek Court has been constructed, the existing home will be required to change their driveway access and street address to Bridle Creek Court and eliminate the existing access through Lots 7 and 8 and Outlot B. Lymnore Addition March 17, 1999 Page 13 EROSION CONTROL Erosion control fence needs to be incorporated along the grading limits on Lots 3, 4, 5 and 7. Erosion control fence needs to be extended along the pond construction limits on Lot 5 and tree protection fencing around the trees to be preserved on the site. Tree protection fencing shall be incorporated onto the grading, drainage and erosion control plan. Subdivision Findings: 1.

HJ.t=ION H~UON CARVER COUNTY PUBLIC WORKS DEPARTMENT Carver County Government Center Administration Building 600 East Fourth Street Chaska, Minnesota 55318-2192 Phone (612)'361-1010 Fax (612) 361-1025 Administration Parks Engineering Highway Maintenance Surveying & Mapping July 20, 1998 To: From: Subject: Sharmin AI-Jaff, Planner II, City of Chanhasserjb Bill Weckman, Assistant County Engineer Preliminary Plat "" V Lynmore Addition (98-1 PUD and 93-4 VAC) Carver County has the following comments and questions regarding the Lynmore Addition Preliminary Plat transmitted to Carver County by your memorandum dated July 9, 1998. These comments and questions are based on the information submitted. Further comments and concerns may develop as this proposal advances. Galpin Boulevard (CSAH 19) was recently reconstructed as an urban roadway with curb and gutter. Any curb cuts and access construction would be the responsibility of the developer. It is expected the entrance design will be similar to the entrance at Bridal Creek Trail. Has a plan been developed to consider the future access of the parcel to the north of this plat? The desire of the County is to limit the number of accesses to CSAH 19 to as few as needed. Has a lot layout concept been considered that would allow future access to the parcel to the north? Any public utility lines that are to be installed within the CSAH 19 right-of-way are subject to the utility permit requirements of Carver County. o Any proposed grading and installation of drainage structures within the right-of-way of CSAH 19 is subject to review and approval of the County Highway Department. The existing storm sewer system, though it is in the County Road, is a City utility. Has it been determined that the main system has adequate capacity to handle the run off from the cul-de-sac without causing runoff problems onto CSAH 197 o 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 fight-of-way. A clear understanding of this responsibility will result in fewer project oversight problems for both the county and the city. The County must approve any trees or landscaping completed within the right-of-way. When . ,. .., A~rmafive Action/Equal Opportunity Employer Printed o~ ]0% Poxt-Con.s'z~mer Recycled Paper locating shrubs and trees, consideration should be given to maintaining an acceptable sight distance at the CSAH 19 intersection. Any trees or shrubs overhanging into the right-of-way could be subject to trimming for safety or overhead utility consideration. Thank you for the opportunity to comment on the preliminary plat for the proposed development.
