2655 North Shore Drive Narrative for the CUP The homeowner is planning to build a new residence on their existing property at 2655 North Shore Drive, on the north side of Crystal Bay on Lake Minnetonka. The property is just under 2 acres at 83,277sf, and is zoned Lakeshore Residential LR -1 A. A Demolition Permit was obtained to remove the existing home, detached garage and small cabin like structure. The site will be regraded to accommodate the new structure and blend better with adjacent properties. Also, it was determined that the current soil was not suitable for the proposed home. Additional excavation, new engineered fill, and additional grading will be required. More than 500 cubic yards of dirt will be moved, imported and exported from the property, triggering the need for a conditional use permit. Also, with this regrading, the proposed grade along the front entry will establish the new high elevation that the building height is measured from, elevation 941.9. Generally, the property now appears to be relatively flat, but does slope from the middle of the lot to the east and south. The mass earthwork analysis for the entire site is 2,046cy of cut, 1,648cy compacted fill, and 397.9cy of excess fill to be removed from the site. A unique feature of this lakeshore property is that there is a small inlet on the neighbor's property just beyond the east property line. It requires a 75' setback from the lake and along much of the east property line. Grade currently varies from elevation 930 near the water to about 939.2 at its highest point, which is on the western middle part of the property where the existing home was. The existing home built in the 1920's had been added onto a number of times over the years. The owner purchased the home in April of 2013. The existing home had a history of moisture intrusion and mold. The existing basement was not really usable, and the floor elevation was below the current minimum floor elevation allowed on the lake today. The existing plan was cut up with a lot of rooms. The new proposed structure will be a 2 -story home, New England shingle style with stone, and with a full-sized lower level walkout. The lower level floor elevation set at the minimum allowable elevation above the lake high water line determines the main level floor and garage elevations. Building up grade to about +4' along the north front face of the home will make the home feel naturally set into the site. There is little movement of soil needed at the western, southern lake and east sides. The entry drive will also be moved to the eastern side of the property to allow for more privacy from North Shore Drive and safer access. The new driveway will also need to be raised coming off the street.
