most areas in the shoreland areas, but would make allowances for higher densities in areas identified in the plan. 3. IMPERVIOUS SURFACE COVERAGE The purpose of the lot coverage inventory in the Shoreland Management Plan was to determine, by zoning district, the areas of the City which contain lot coverage below and above the maximum allowed by the DNR shorelana standards. The City wc.s broken down into separate shorelanc areas; Lake Minnetonka and Gleason Lake. These differentiations were made because of the different classification of the water bodies and because of the differing intensity of development. Each separate area was further divided into separate zoning districts for the lot calculations to determine lot coverage and open space. City records were used to identify each parcel and its lot size. Using aerial photographs and section maps with superimposed buildings, lot coverage was calculated by measuring the footprint area of all structures, accessory structures and driveways. Subtracting this calculation from total lot size provides the remaining open space. The eunount of surplus/deficit let coverage is determined by computing the maximum allowable impervious surface coverage by DNR standards. Actual lot coverage was subtracted from the allowable coverage to determine each lots surplus or deficit lot coverage. Table 4 indicates the cunount and percentage of impervious surface coverage for each zoning district.
