Prior Lake, MN 55372-1714 MEETING DATE: AGENDA #: PREPARED BY: AGENDA ITEM: DISCUSSION: MAY 2, 2005 9C JANE KANSIER, PLANNING DIRECTOR CONSIDER APPROVAL OF A RESOLUTION APPROVING A PRELIMINARY PLAT TO BE KNOWN AS BELMONT ESTATES Histo~.: Arcon Development has applied for approval of a preliminary plat to be known as Belmont Estates on the property located north of 165th Street and CSAH 12, east of Marschall Road, south of Howard Lake, and directly west of the Stemmer Ridge development. The Planning Commission considered this request at a public hearing on April 11, 2005. The Planning Commission voted to recommend approval of the preliminary plat. Drail minutes of the Planning Commission meeting are attached to this report. PhFsical Site Characteristics: Total Site Area: The total site consists of 25.55 acres. Tooography: This site has fairly level topography, with elevations ranging from 976' MSL at its highest point to 964' MSL at the lowest point. Vegetation: This site has been historically cropped. There are few, if any, trees on this site. Wetlands: Howard Lake abuts the north and east boundary of this property. There is a wetland located along the south side of the lake. This plat will have no impact on the wetlands. Access: Access to the site is from the Stemmer Ridge development to the east and from CSAH 17 (Marschall Road) to the west. 2020 Comprehensive Plan Designation: This property is designated it for Low to Medium Density Residential uses. L:\05 FILES\05 SUBDIVISION\05 PRELI~rr:~t.@§~,C report.doc Phone 952.447.4230 / Fax 952.447.4245 Zoning: The site presently zoned R-1 (Low Density Residential). The R-1 district is consistent with the proposed R-L/MD designation. This district permits a maximum density of 3.6 units per acre. Shoreland: The site is also located within the Howard Lake Shoreland District. Howard Lake is designated as a Natural Environment Lake; the minimum lot area and lot width requirements in this district are 20,000 square feet and 100 feet, respectively. Proposed Plan Lots: The preliminary plat consists of 33 lots for single family dwellings and 3 outlots. The lots range in size from 20,000 square feet to over 33,000 square feet. All of the lots meet the minimum lot area and lot width requirements for the R-lSD district. The three outlots are to be used for drainage purposes. The outlots will be dedicated to the City. Streets: This plan proposes three new public streets. Street A is an east-west street extending from Stemmer Ridge on the east to CSAH 17. This street is designed as a local street with a 60' wide right-of-way and a 32' wide surface. The DNR has expressed some concerns about the setback of this street from the OHW for Howard Lake. Section 1104.403 of the Zoning Ordinance generally required streets to maintain the minimum Shoreland setback, 150' in this case. At its closest point, Street A is located 70' from the Howard Lake OHW. Section 1104.403 (2) also states, "If no alternative exists, they may be placed within these areas, and shall be designed to minimize adverse impacts." In this case, the location of Street A is determined by the street location in Stemmer Ridge, the approved access point onto CSAH 17 and the existing lots to the south. The applicant has moved the street as far away from the OHW as possible, and is proposing several trees along this segment of road to minimize the impact. Street B is located on the north side of Street A, and provides access to the Schneider property to the north. This street is also designed as a local street with a 50' wide right-of-way and a 32' wide surface. Street C is located on the south side of Street A, and is an extension of Palomino Street as platted in the Autumn Acres subdivision to the south. Street C is designed as a local street with a 60' wide right-of-way and a 32' wide surface. L:\05 FILES\05 SUBDIVISION\05 PRELIM PLA~Belmont Estates\CC report.doc The access onto CSAH 17 from Street A requires a permit from Scott County. To allow this access, the County is requiring the removal of the access at 165th Street to the south. The developer has agreed to remove this access point and provide a cul-de-sac at the west end of 165th Street. The developer must also construct Palomino Street from Street A to 165th Street. This plan is complicated by the fact that 165th Street and Palomino Street are currently located outside of the City limits. The developer will need to obtain written permission from Spring Lake Township to complete this work. The City will include the costs for construction of these roads in the development contract. Sidewalks/Trails: The plan includes a trail on the north side of Street A. Parks: There is no parkland included within this plat. A neighborhood park is located adjacent to this property within the Stemmer Ridge development to the east. The parkland dedication requirements for this plat will be satisfied by a cash dedication in lieu of land. Sanitary Sewer/Water Mains: Sanitary sewer and water mains will be extended from the utilities to be located within the Stemmer Ridge development. Storm Sewer: The plan directs the runoff from a portion of the site to the NURP ponds located in Outlot C at the northeast comer of the site. These ponds will also accommodate the runoff from Stemmer Ridge and Berens Woods. Arcon Development will be developing all three subdivisions. Runoff from the west side of the plat will be directed to a pond located in Outlot A at the northwest comer of the site. The City and the Prior Lake/Spring Lake Watershed District are currently reviewing this plan. .Densi,ty: The development proposes 33 single family units. The gross density in this plan is 1.34 units per acre. The proposed density is consistent with the 3.63 units per acre permitted in the R-1 Use District. Landscaping: Single family developments require at least 2 front yard trees per lot. The developer has provided a plan showing at least 4 trees per lot. Tree Replacement: The applicant has not submitted a tree inventory; however, 2003 aerial photographs of the site do not show any existing trees. L:\05 FILES\05 SUBDIVISION\05 PRELIM PLA~Belmont Estates\CC report.doc ,ISSUES: ,CONCLUSION: Fees and Assessment: This development will be subject to the standard development fees. In addition, the development will be subject to a lateral assessment for the extension of sewer to the site. The applicant proposes to subdivide the property into 33 lots for single family dwellings. All of the lots meet the minimum lot area and lot width requirements. The overall layout of the plat appears appropriate, given the constraints of the site. In the memorandum dated April 6, 2005, the City Engineer has identified several design issues. These issues must be addressed prior to final plat approval, and in some cases, prior to any grading on the site. The preliminary plat application will comply with relevant ordinance provisions and City standards, provided the following conditions of approval are met: 1. A final plat for this site will not be approved until the final plat for Stemmer Ridge has been approved. 2. The developer must obtain written permission from Spring Lake Township for the construction of the 165th Street cul- de-sac and Palomino Street prior to final plat approval. Any temporary easements or permanent right-of-way from adjacent residents must be obtained prior to final plat approval. 3. All necessary permits from Scott County must be obtained prior to any grading on the site. 4. The wetland boundaries and proposed buffers must be shown. All wetland areas shall be shown in drainage and utility easements if they are not contained in outlots to be dedicated to the City. 5. All buffers shall be shown in drainage and utility easements or have conservation easement documents filed concurrently with final plat approval. 6. Buffer monurnentation shouM be shown on plans. 7. The Grading Plan must be revised as follows: a.

Questions from Commissioners: Stamson questioned why staff requested the cul-de-sac in Berens Woods be connected with Street A? Kansier responded they did not want to disturb the wetland. Stamson questioned Street B and Palomino Drive design- Albrecht explained the shoreland and wetland areas and didn't feel it was a proper extension. Another concern is for services to the north. This was the best access. Stamson agreed. Lemke questioned Street C and D access. Albrecht said they are locked into Street C and explained the spring-time drainage issues and the outlet. The developer is in the process of working with a solution. The goal is not to impact the residents. Ringstad questioned why the City is paying for the oversize watermain. Albrecht said the development is only required to have an 8 inch watermain. However, in the future the City will have a well to the west and it would be one of the trunk arterial lines supplying water from potential wells in the area. Billington questioned the current time frame for Stemmer Ridge development. Kansier responded the developer has submitted information and suspects that all three developments will start at one time. Once they are all approved they can begin construction which would be better for the existing neighborhood. Probably start this summer. Comments from the Public: Dustin Kern, Arcon Development, said staff did a wonderful job with the project. A few issues have to be worked out however the engineers are working on staff's concerns. Arcon took over this project a few weeks ago and are now the fee owners. They will still meet with the neighbors. Kern did not see any particular engineering problems. L:\05 FILES\05 PLAN COMMISSION~05 MINUTEShMN041105.doc Planning Commission Meeting ~4pri111, 2005 Paul Hofslien, 1896 165th Street East, stated he was concerned about the drainage and looks forward to the neighborhood meeting. The meeting closed at 7:15 p.m. Comments from the Commissioners: Perez: · The project sounds encouraging from staff and the developer. There is no impact to the wetlands. The densities are well below the maximum for the zoning designation. Questioned staff on minimizing the adverse impacts with the shoreland and wondered if there was anything different that could be done with the trees? Albrecht responded the way Berens Woods and this development are laid out actually minimizing things greatly. Trails give the development bigger natural buffers. The property to the north will not be disturbed. Disturbing the area as little as possible is the best way to not impact. The developer is also proposing ponding that meets and exceeds the City's requirements. · For the most part this should be a minor impact to the shoreland area. · Approve. Lemke: · Initially thought this might be premature however if the talented staff is comfortable moving forward with the preliminary plat, than I am comfortable. · The developer has taken a lot of steps to address the concerns of the residents. · Approve. Billington: · There has been more than reasonable diligence with the management of the issues. · Support. Ringstad: · Support. · Thought there may be comments with the cul-de-sac. Glad to see Arcon is going above and beyond the requirements with the wetland plan. · Agreed with comments from fellow Commissioners. Stamson: · Agreed with all. It is an appropriate design for the area. It meets the land use criteria. · Concern with Street B to the north. · Support and recommend approval to the Council.

I reviewed the revised Belmont Estates preliminary plat and offer the following comments for consideration. Howard Lake is a Natural Environment (NE) basin subject to the provisions of the City's shoreland zoning regulations. The ordinary high water elevation (OHW) is 957.2'. The final plat drawings should include the DNR identification number of 70-73P, and the OHW elevation. The minimum lot size for non-riparian lots is 20,000 square feet. Lots 5, 6, and 7 of Block 2 are slightly short of the minimum lot area. Adjustments should be made to bring these to the 20,000 square foot minimum. Similarly, Lots 4and 5 also are a foot short of the required 100-foot minimum lot width. I note that on the bottom of the plan sheet it indicates lot dimensions and areas are approximate, and that negotiations are underway with an adjacent property owner to bring some lots in conformance with Shoreland minimums. The information in the Development Data Table needs to be corrected. It indicates the required lot width is 86 feet, and minimumlot area 12,000 square feet. As mentioned earlier, minimums required in Shoreland, for which most, if not all of the site is located, is 100'width and 20,000 square feet for non- riparian sewered lots. There is a diagonal line through lots 6 and 7 of Block 2 that is identified as "Topographical Divide/Shoreland District Boundary". It is not clear what this is illustrating. The shoreland district extends 1000' from the OHW of Howard Lake, and can only be considered for change by the Commissioner of DNR, and only after a request and supporting documentation from the city. This notation should be removed from the plat drawings. Finally, "Street A" is located within the l.~,,er" setback from the lake. Section I. '~ u-,.-,,,.o t.~.'"~ ,,r,, ,-,x of the ~"-'"- ,-, ..... a ~t~ ~- oh~,,.l..., ordinance, based upon the state standards for shoreland, require that streets meet the structure setback unless no alternatives exist. With the proposed plat, alternatives do exist that would keep the road at the required setback. The alternative would likely result in the reduction in the number of lots. The plat does not provide any information as to how stormwater willbe managed. Thanks for the opportunity to comment on the proposed preliminary plat.
