Narrative for City Submittal 6965 and 6957 Cottage Grove Avenue, Minnetonka Approvals Requested: () Preliminary Plat and Final Plat approval at 6965 and 6957 Cottage Grove Avenue; (2) Variance to declare the lot buildable; (3) Lot area variance; (4) Buildable area variance; (5) Sanitary Sewer easement vacation; Property Owner: David Olshansky, Lots & 2; Mark Olshansky, Lots 3 & 4; Civil Engineer and Land Surveyor: EVS, Inc. Existing Land Survey Information A Certified Land Survey was completed on April 9, 206 and is attached to this report. It includes property legal boundary description, utilities, topography, trees, landscaping, building structures and unique appurtenances located on the surveyed property. The description of the property surveyed includes Lots, 2, 3 and 4, Block 7, THORPE BROS GROVELAND SHORES, Hennepin County, according to the recorded plat thereof. We are still researching the property legal description material since the early 900's to locate the easement description for the existing Sanitary Sewer that runs east-west through the subject property and serves two homes on Beechwood Avenue. When this material is located, it will be transmitted to the City. It is expected this will be available on June 6th. Development Plan Request It is the intent of the land owner to construct a new home on Lots 3 and 4. These lots are currently combined into one overall property made up of Lots, 2, 3, and 4 located on Cottage Grove south of Gray's Bay Blvd. The request is to reorganize these four lots into a new Plat including two lots as shown on the attached Preliminary Plat. The current arrangement of the lots on the Hennepin County Property Data base is as follows: Address PID Lot Area 206 Taxes 6965 Cottage Grove #772220040,870 sf $5,3 6957 Cottage Grove #77222004 5,386 sf $366 6957 Cottage Grove #772220042 6,358 sf $526 The current property at 6965 Cottage Grove has a single family residence structure with garage and driveway. The property is currently zoned R- low density residential. The property is wooded and slopes EVS 0025 Valley View Rd., Suite 40 Eden Prairie, MN 55344 Phone: 952.646.0236 Fax: 952.646.0290 www.evs-eng.com
to higher elevations from Cottage Grove to the east. All drainage on the property flows to Cottage Grove Avenue. Due to the irregular shape of the lot and right-of-way, the minimum buildable area of 3,500 sf would not be met on the new lot. However, the applicant requests the city to take into consideration that if the right-of-way were curved as is often the case, the proposed lot would have approximately 3,560 sf of buildable area. The property owner is also willing to negotiate any right-of-way turnback that would not affect the effective width of the right-of-way. There is an existing 8" sanitary sewer line that serves two properties on Beechwood Avenue and flows into the Sanitary Sewer line in Cottage Grove street right of way. To allow the new structure to be constructed on 6957 Cottage Grove It is proposed to remove the existing sewer and re-align the new 8" sewer within a 20 foot easement on the northerly edge of Lot 3. Attached is a schematic layout of the proposed sewer line within the 20 foot easement. This new line will be buried approximately 8 feet deep. Cottage Grove is part of the Libbs Lake neighborhood street reconstruction project. It is hopeful, schedule permitting, that the sewer line will be relocated to the location shown on the attachment during the schedule for the street reconstruction of the utilities within Cottage Grove Avenue. This is schedule to occur during June - July, 206. The following is a summary of the project elements proposed (graphically shown on the attached plan sheets): Proposed Plat Data Lot Dimensions for new lots 3 & 4: Minimum Width 0 feet Minimum Lot Depth 25 feet Lot Size,744 sf Minimum Buildable Area, based upon setbacks 2,700 sf Max Lot Impervious Area 25% Setbacks Total Combined Side Yard Setbacks Front Setback Rear Setback 30 ft 35 ft 40 ft Site Access The proposal will require the addition of a new private driveway to Cottage Grove Ave. Grading The existing site has good drainage from the west edge of the lots toward Cottage Grove Avenue. Stormwater practices will meet the City stormwater management requirements. The Sanitary Sewer relocation plan also includes a conceptual grading plan. The specific building plan, at the time of building permit application, will include a more detailed grading and drainage plan.

Sanitary Sewer and Watermain It is hopeful that this project will be approved in time to allow coordination with the ongoing street and utility reconstruction project in the Libbs Lake neighborhood. A water service stub will be requested for the new parcel. Additionally, the sanitary sewer for the new structure will utilize the new sanitary sewer line that will be relocated on the new 20-foot easement. Tree Preservation A few trees will need to be removed as part of the new sanitary sewer construction project. The final construction plan for the building permit will be more detailed concerning tree removal. The tree removal will be below the 35% allowable tree removal threshold. Architecture for the New Residential Structure and the Existing Residential Structure It is planned to construct a two level house with basement and attached garage. Upon the lot split approval, the building plans will be immediately submitted for building permit approval. The existing structure on Lots and 2 is proposed to be completely renovated. Attached is a schematic rendering of the house and garage structure that is planned for the site and that will meet the 2,700 buildable area requirement. Project Schedule If the City approves the proposed lot split, the utility project will be immediately initiated with the new 8" sanitary sewer line being constructed. The neighbors to the east fronting on Beechwood Avenue have been communicated with and are aware of the general plan. A neighborhood meeting will be scheduled to precede the Planning Commission meeting on this proposal. Report attachments detailing the project proposal.
