new outdoor storage area to be designated for the LMCD harvesters. (Please refer to Exhibit H for the proposed site plan.) A new circulation plan and parking plan has required the County to develop a stormwater management plan for the site as it is located within 1000 feet of the Ordinary High Water Level (OHWL) of Lake Minnetonka. The County has proposed to construct a stormwater pond on the site to treat surface water runoff and for rate control. Proposed stormwater pond would be constructed within an existing wetland area that is under the jurisdiction of the Minnehaha Creek V/atershed District (MCWD). County staff has indicated 3,947 square feet of a type 3 wetland would be impacted by the project. The wetland loss for the purposes of a stromwater pond will be mitigated on-site and will exceed the 2:1 replacement ratio. This application requires the following approvals: 1. A Zoning Code Amendment would allow the County Maintenance Facility to exist in the LR-IC zoning district. The facility was constructed at a time when the property was zoned for commercial purposes, however, that zoning changed to residential in the early 1970's, hence use of the property for the maintenance facility has continued as a legal non- conforming use. (Section 10.25) 2. Variance to permit hardcover alteration within the 500-1000 foot setback from the OHWL of Lake Minnetonka. The proposed hardcover would result in a reduction of impervious surface from 148,835 square feet (61%) to 138,188 square feet (57%), where 35% coverage is allowed in the setback. (Section 10.22, Subdivision 2 and 10.56, Subdivision 16 (L) (2)) 3. Variance to permit the sand/salt storage facility to exceed the maximum allowed height for a structure and exceed the defined height of the principal structure on the property. The proposed structure would be 42 feet in height. (Section 10.03, Subdivision 9 (B) and (C) (3)) 4. Variance to permit the sand/salt storage facility to exceed the maximum allowed size for an oversized accessory structure on a 6.65 acre lot. The Code permits a 2,400 square foot oversized accessory structure on the property. The proposed building is 70 feet X 112 feet in size, 7,840 square feet. The same section of the ordinance permits tb ? total aggregate of all accessory structures on this property is 4,800 square feet. According to the most recent site plan the total proposed square footage for accessory buildings is only the salt/sand storage facility (7,840 square feet). (Section 10.03, Subdivision 9 (C) (2)) The accessory building is subject to a restrictive covenant that states the following: 1) No future subdivision will be approved that places the structure within a lot that has no principal structure, except that the City in its subdivision approval may grant a finite time period in which the oversized accessor>’ structure may ^2535 Hannep,^ County 3880 Shoreline Drive Zoning Code AmendmenV'Condtttonal Use Permit Variances 1/19 00 Page!
