The application includes the following request: . A Preliminary Plat consisting of 27.317 acres to be subdivided into 34 lots for single family development. . Approval of a Wetland Replacement Plan. This agenda item requests City Council approval of the preliminary plat and of the Wetland replacement Plan. Historv The north 20 acres of this property was annexed in 2004, in the first phase of the Orderly Annexation Agreement. The south 7 acres was annexed in 2005 by petition of the property owner. In accordance with the City Zoning Ordinance, the property was automatically zoned R-1 at the time of annexation. The original preliminary plat for this development was submitted as a standard development, meeting all minimum lot areas and frontages. It was revised to include smaller lots at the suggestion of the staff as a result of the work of the Tree Preservation Task Force, a committee created by the City Council to look at the provisions of the Tree Preservation Ordinance. The Task Force has been working on a new Tree Preservation Ordinance, a component of which is a mechanism intended to provide flexibility in areas identified high and moderate quality natural environments, identified by the Natural Resources Inventory recently completed by the City. The intent is to offer a process that will provide maximum design flexibility, without the need for a full-fledged Planned Unit Development. This process would allow the developer to modify street right-of-way and surface widths, lot areas and lot widths, and structure setbacks. Its scope is more limited than a standard Planned Unit Development process in that it does not allow increased density or unit types not otherwise permitted. The idea is to preserve the natural environmental features. This site is identified as a quality natural environment, specifically for the maple/basswood forest located on the site. The staff used Golden Pond as an example to illustrate how the proposed ordinance could work, and what the benefits would be. In this case, the flexibility saves, at a minimum, 24 16" to www.cityofpriorlake.com . ,,, .,,' Phone 952:440.96'75 / FaX,952A4'O.cg678 36" maple trees (480 total caliper inches). Once we had identified this benefit, the staff felt this opportunity should not be lost and we should try to carry this plan forward, even though the ordinance is not in place. Since the preliminary plat application was not yet complete, the developer was amenable to revising the plan as suggested. The proposal also provides the developer significant cost savings in terms of tree replacement and infrastructure. As mentioned, a new Tree Preservation Ordinance has not been adopted, so variances to the minimum lot area and lot width are necessary. The staff discussed this proposal with the DNR, and they have no objections to the variances. The DNR feels the environmental benefits provide a justification for the reduced lot areas and lot widths. The Planning Commission held a public hearing on the variance requests and on the preliminary plat on July 24, 2006. The Planning Commission approved the requested variances on the basis the variances would conserve natural resources and environmental assets of the community. The Planning Commission also recommended approval of this preliminary plat subject to the following conditions: 1. The tree protection plan must be revised to indicate which trees will be saved, which trees will be removed for road and utility purposes, and which trees will be removed for building pads and driveways. A tree replacement plan, consistent with the requirements of the current zoning ordinance must be submitted. 2. A landscaping plan for the required subdivision trees must be submitted. 3. Revised plans addressing the Grading Plan and Hydrology and Storm Sewer comments listed in the Engineering memorandum dated June 12, 2006, must be submitted and approved prior to issuance of a grading permit. 4. A revised preliminary plat showing lot dimensions and areas must be submitted prior to submittal of a final plat application. 5. Revised plans addressing the Plat, General, Streets and Utilities issues listed in the Engineering memorandum dated June 12, 2006, must be submitted and approved prior to submittal of a final plat application. Wetland ReDlacement Plan On January 18, 1994, the City Council passed Resolution 94-01 adopting the permanent rules of the Wetland Conservation Act (WCA) of 1991. Along with this, the Council also assumed the role of local government unit (LGU) for making WCA determinations for landowners. The purpose of WCA is as follows: 1. Achieve a no net loss in the quantity, quality, and biological diversity of Minnesota's existing wetlands; 2. Increase the quantity, quality, and biological diversity of Minnesota's wetlands by restoring or enhancing diminished or drained wetlands; 3. Avoid direct or indirect impacts from activities that destroy or diminish the quantity, quality, and biological diversity of wetlands; and 4. Replace wetland values where avoidance of activity is not feasible or prudent. The Golden Ponds project wetland replacement plan application proposes to impact 0.56 acres of Type 2 wetland and 0.73 acres of Type 3 wetland, totaling 1.29 acres. Replacement of this impact will occur through both on-site mitigation and wetland bank purchase exceeding the requirements of the WCA. 0.52 acres of New Wetland Credit (NWC) is proposed to be created on site, along with 0.52 acres if Public Value Credit (PVC). An additional 0.45 acres of PVC will be claimed thought the creation of stormwater ponds on-site. A bank purchase will be made in the amounts of 1.41 acres of NWC. The WCA Technical Evaluation Panel (TEP) reviewed the proposed impacts and mitigation on April 20, 2006 and recommended changes. Changes consistent with TEP recommendations were made by the applicant. The complete wetland replacement plan application was received on January 19, 2006. The comment period was completed on February 10, 2006 for the project with no written comments received. Attached is a copy of the TEP "Findings and Conclusions" for this project, which is the basis for the staff recommendation Current Circumstances The developer is proposing to develop this property with 34 lots for single family homes. The following paragraphs outline the physical characteristics of the existing site, the Comprehensive Plan and zoning designations, and a description of some of the specifics of the site. PHYSICAL SITE CHARACTERISTICS: Total Site Area: The total site consists of 27.317 acres. The net site area, less existing wetlands, is 24.698 acres. TODoaraDhv: This site has a varied topography, with elevations ranging from 998' MSL at its highest point to 952' MSL at the lowest point. The majority of the site currently drains towards the wetland located at the center of the site. The eastern portion of the site drains towards Rice Lake. Veaetation/Existina Uses: There is an existing house and outbuildings located at the southwest corner of the site. These buildings will be removed. The south half of the site is heavily wooded. The north half of the site has been cropland and pasture. A tree inventory identified 4,730 caliper inches of significant trees on the site. This area is identified as part of the Natural Maple/Basswood Forest on the City of Prior Lake Natural Resource Inventory. The site is subject to the Tree Preservation requirements. Wetlands: There are four jurisdictional wetlands located on the site, totaling 3.9 acres. The plan proposes to impact 1.07 acres of the wetlands. The impacted wetland is a small wetland located on the north side of the site. The impact will be mitigated on the site. The Technical Evaluation Panel (TEP) has reviewed and approved the wetland mitigation plan. The City Council is being asked to approve the plan as part of the preliminary plat review. Access: Access to the site is from Turner Drive, located in Maple Glen 2nd Addition to the west. Turner Drive will also connect to Hickory Shores on the north side of the development. The proposed plat also provides for a future connection to the property to the south. Access to the property directly east of this site, along the shoreline of Rice Lake, is part of a larger parcel with access from 180th Street to the south. 2020 ComDrehensive Plan Desianation: This property is designated it for Low to Medium Density Residential uses. Zonina: The site presently zoned R-1 (Low Density Residential). The R-1 district is consistent with the existing R-UMD designation. This district permits a maximum density of 3.6 units per acre. Shoreland: A portion of this site is also located within the Rice Lake Shoreland District. Rice Lake is designated as a Natural Environment Lake; the minimum lot area and lot width requirements for this lake are 20,000 square feet and 100 feet, respectively. PROPOSED PLAN Lots: The preliminary plat consists of 34 lots for single family dwellings. The lots range in size from 16,000 square feet to over 39,000 square feet; lot widths begin at 90 feet. The applicant is requesting variances to the minimum lot area and lot width for the lots less the 20,000 square feet and 100' in width. The rationale for the variances request is discussed later in this report. Streets: This plan proposes three new public streets, as listed below. . Turner Drive is located on the north side of the plat and extends 800' from Maple Glen 2nd Addition on the west to Hickory Shores on the north. The street is designed as a local collector street with a 66' wide right-of-way and a 32' wide surface. . Golden View Lane is a north-south street extending 1,300' from Turner Drive to the south boundary of this plat. It is designed with a 55' wide right-of-way and a 28' wide surface. . Maplewood Drive is a 500' long cul-de-sac located on the south side of the plat, west of Golden View Lane. It is designed with a 50' wide right- of-way and 28' wide surface. SidewalkslTrails: Sidewalks are located along the north side of Turner Drive and along the west side of Golden View Lane. Parks: There is a 1.25 acre neighborhood park located in the northwest corner of this site. This park becomes part of the 29 acre park system stretching from 170th Street to TH 13 in the Heritage Landing, Hickory Shores and Maple Glen developments. This portion of the park is relatively flat upland, and will be the site of a playground structure. The land dedication satisfies 50% of the required dedication. The remaining requirements will be satisfied by a cash dedication calculated at 50% of the total lots times the current per unit cash dedication. Sanitary Sewer: The sanitary sewer in this development is designed to flow to a lift station located at the center of the site on the west side of Golden View Lane. The lift station will then pump the sewage back to the gravity line located in Maple Glen 2nd Addition. The sanitary sewer lines are extended to the south and west property boundaries to provide for future connections. Water Mains: Water main will be extended from the existing line located in Turner Drive. The development plans also provide for future connection to the west and to the south. Storm Sewer: The stormwater runoff on this site is directed via storm sewer pipe and grading to a pond located on the east side of Golden View Lane. This pond is sized to handle this runoff as well as some of the runoff from the Hickory Shores development. Densitv: The development proposes 34 single family units. The net density in this plan is 1.24 units per acre. The proposed density is consistent with the maximum 3.63 units per acre permitted in the R-1 Use District. Landscaoina: Single family developments require at least 2 front yard trees per lot. The developer has not provided a landscaping plan for this development. Tree Reolacement: The applicant has submitted an inventory identifying 4,730 caliper inches of significant trees on the site. The Zoning Ordinance allows up to 25% of the significant caliper inches to be removed for road and utility purposes, and up to 25% for building pads and driveways. The number of significant inches removed over and above these percentages must be replaced at a rate of a 1/2 caliper inch for each inch removed. This plan proposes to remove 47% of the total caliper inches of significant trees on the site. The plan does not identify the number to be removed for roads and utilities from those removed for building pads and driveways. The tree inventory needs to be revised to include this breakdown. ISSUES: Preliminarv Plat: The general layout of the plat appears appropriate, given the constraints of the site and the City's desire to be sensitive stewards of the environment. The Planning Commission and staff recommend approval of this development on the basis it is consistent with the provisions of the Zoning and Subdivision Ordinance. This recommendation for approval is subject to the conditions listed on page 2 of this report. Wetland Reolacement Plan: The Wetland Replacement Plan is consistent with the Wetland Conservation Act and City of Prior Lake ordinances. The staff recommends approval of this request. FINANCIAL IMPACT: There is no budget impact as a result of this action. Approval of the project will facilitate the development of the area and increase the City tax base. ALTERNATIVES: The City Council has the following alternatives: 1. Adopt a resolution approving the Preliminary Plat for this development subject to the listed conditions, with the finding that the preliminary plat is consistent with the intent and purpose of the Zoning and Subdivision Ordinances, and adopt a resolution approving the Wetland Replacement Plan for the Golden Pond Development. 2. Deny the Preliminary Plat on the basis it is inconsistent with the purpose and intent of the Zoning and Subdivision Ordinances and/or the Comprehensive Plan, and deny the Wetland Replacement Plan for the Golden Pond Development. In this case, the Council should direct the staff to prepare a resolution with findings of fact based in the record for the denial of these requests. 3. Defer consideration of this item and provide staff with specific direction. The Planning Commission and staff recommend Alternative #1. RECOMMENDED MOTIONS: 1. A motion and second adopting a resolution approving a Preliminary Plat to be known as Golden Pond, subject to the listed conditions. 2. A motion and second adopting a resolution approving the Wetland Replacement Plan for the Golden Pond development. ~evS iJ Frank Boyle Ci A RESOLUTION APPROVING THE PRELIMINARY PLAT OF "GOLDEN POND" SUBJECT TO THE CONDITIONS OUTLINED HEREIN.

The trees located off of Maplewood drive are identified as unique in the City's Natural Resource Inventory. The City wishes to provide some lot flexibility as a way to save some of these large maple trees which could amount to some financial savings for the development. Revisions to the plat and grading plan will be necessary for saving these trees. Please schedule a meeting with the Development Review Committee. 2. Minimum low floor elevations for pads adjacent to ponds and wetlands shall be 2' above the 1 DO-year HWL elevation. The lowest opening shall be 2' above the emergency overflow. (This condition is not met on lots 4-6 blk 3, lot 1 blk 6, and lot 7, blk 5) Plat Issues 1. Additional easement is necessary for placement of the Maple Drive cul-de-sac. 2. 3. Remove surface features from the preliminary plat. Revise line work for the drainage and utility easement for swales. easements should be a part of the overall easements for the lots. These General 1. Permits from PLSL Watershed District, NPDES permit, and a SWPPP must be obtained prior to grading. 2. Show easements for work outside of property limits. 3. Provide legend showing all hatches and Iinetypes used on all plan sheets. Gradina Plan C:\Documents and Settings\jane.PRIORLAKECffiLocal Settings\Temporary Internet Files\OLK5A\review 060906.DOC 1. Grading easements will be required for the work outside the property lines. 2. Lot 3 Blk 4 is labeled incorrectly on the grading plan. 3. Show wetland buffer and buffer signs on the grading plan. 4. Slopes of maintained areas must not be greater than 4:1. Grading in backyard areas must be sloped greater than 2%. In flat areas, proposed grading should meet the minimum slope requirements in order to avoid low points which could be potential wet spots. 5. Grading for storm pond 1 is shown into the roadway, please revise. 6. Silt fence installation should be shown outside the grading limits. 7. Provide low floor elevations for lots adjacent to proposed park. Minimum low floor elevations for pads adjacent to ponds and wetlands shall be 2' above the 100-year HWL elevation 8. Numerous driveways will exceed the maximum 10% (ex. Lots 3-4 Blk 4), please verify and revise driveways. 9. All backyard drainage swales shall be contained within a drainage and utility easement. Provide easement for proposed swales on the grading plan. 10. The erosion control measures shall be installed and inspected prior to any site grading. All trees to be saved must be protected by silt fence or construction fencing around the drip line of the tree to protect the root system. This fencing must be installed prior to any grading on the site. Provide emergency contact person for erosion control on the project. 11. Provide access for water quality ponds. Pond access paths should be paved and have a maximum grade of 8% and be a minimum of 10' in width. The pond access paths should extend to the bench of the pond. 12. Provide spot elevations or grades for properties adjacent to the proposed project (lots on Maple Glen 2nd and Hickory Shores). Verify if the contours shown are proposed or as-built grades. 13. There are numerous areas where proposed contours do not tie into an existing contour correctly or is incomplete (ex. End of cul-de-sac), please revise. Minor adjustments of proposed contours should be made. Proposed contours appears to be directing water towards other homes, please revise to show drainage along the easements located on lot lines (example between lots 3 and 4 block 5). Flow arrows may be beneficial to show how the drainage will be conveyed. 14. Provide detail and label drainage swales on the grading plan. Do the swales have a special detail? Please revise swales to keep them under the maximum 300' length. The platting of easements for these swales should be revised to remove overlapping line work. 15. Provide riprap for all storm sewer outlets and show riprap locations on the grading plan. C:\Documents and Settings\jane.PRIORLAKECH\Local Settings\Temporary Internet Files\OLK5A\review 060906.DOC 2 16. Provide concept plan for property to the south and east. Sanitary and water service stubs may need to be provided for properties on the south side of Wedgewood Lane. Hvdroloav and Storm Sewer 1. Sodded channels show up on wetland mitigation sheets and make hatch scheme confusing on that sheet. 2. Dikes used to create rate control ponds must at maximum use 4: 1 slopes and measure 10' wide at top. At minimum, a clay core should be designed in consideration of groundwater flow. If head difference between NWL of pond and downstream land exceeds 3', soils data will be required in the area and dike design must address maintenance of pond water level and dike stability. Outlet pipes through engineered dikes should be designed with anti-seep collars. Specify that sand bedding not be used through dike section. 3. Pond skimmer structure inlet pipe to pond should be set approximately 1.5' below water surface, not at pond bottom. Storage under invert is used for sediment storage. The detail plan and profile views pipe sizes contradict each other. Please clarify. 4. Rock weeper detail should utilize larger open grade rock, to prevent scattering. Possibly 3"+. Weeper detail incorrectly reads "sweeper." 5. Minimum low floor elevations for pads adjacent to ponds and wetlands shall be 2' above the 1 DO-year HWL elevation. The lowest opening shall be 2' above the emergency overflow. (This condition is not met on lots 4-6 blk 3, lot 1 blk 6, and lot 7, blk 5) 6. The wetland bypass outlet pipe flared end section should be placed at the wetland edge or additional easement is necessary from the flared end section to the wetland edge. 7. The design engineer is encouraged to call Prior Lake Water Resources Engineer, Ross Bintner at 952-447-9831 with questions on any hydrological and hydraulic comments. Streets 1. Turner Road shall have a 9 ton design and meet MN/DOT 30 MPH design. Provide pavement analysis and typical sections for all roadways. 2. Provide temp cul-de-sac at the south end of street. Provide street names on the Alignment of proposed Wedgewood Lane may need to be revised to provide a better connection point to the existing Wedgewood Lane. Conceptual layouts including vertical analysis for Wedgewood will need to be evaluated in order to provide service to other areas. 3. The plans should show the installation of 8 foot bituminous trail around lots 1-6 block 4. The Trail should begin at Turner Road west of lot 1, extend to the park structure and terminate at Turner Road north of lot 6. C:\Documents and Settings\jane.PRIORLAKECH\Local Settings\Temporary Internet Files\OLK5A\review 060906.DOC 3 Utilities 1. Utility connections should match those on the Hickory Shores Development on Turner Drive. The rim elevation for the sanitary manhole has a difference of over 1 foot. 2. Service stubs for Lots 1-2 Blk 1 should be shown at the right of way. Shifting of the service locations will keep them out of the cul-de-sac while keeping the stubs at the right of way. 3.
