Because the property currently has 28% hardcover, exceeding the <br /> allowed level of 25%, and because the proposal will not achieve the allowed level of 25% nor <br /> conform to the 15%structural coverage limit,variances are required. <br /> ; --------------------------------------------------------------------------------------- <br /> LOT ANALYSIS WORSHEET <br /> Lot Area/Width: <br /> � LR-1C Required Actual <br /> Lot Area } 0.5 acre 15,338 square feet(0.35 acre) <br /> I Lot Width 100 feet 79' @ OHWL&65' @ 75'setback <br /> _ Setbacks: <br /> LR-1C Required Existing Proposed <br /> Lake 75' 88' Deck 86' Deck <br /> Rear/Street 30' S7.6' House No Change <br /> North Side 10' 12' Deck 11' Deck <br /> South Side 10' 24' Deck 27' Deck <br /> NO The house and deck are currently and proposed to remain <br /> Average Lakeshore encroachment located behind the average lakeshore setback line. <br /> allowed <br /> Structural Covera�e: <br /> Lot Area Allowed 1989 Approva) Existing Proposed <br /> 15,338 s.f. 2,300 s.f. 2,750 s.f. 2,890 s.f. • 2,935 s.f. <br /> 15% 17.9% 18.8% 19.1% <br /> Hardcover Calculations: � <br /> Stormwater <br /> Quality Overlay Property Allowed Existing Proposed <br /> District Area Hardcover Hardcover Hardcover <br /> Tier 1 15,338 s.f. 3,834.5 s.f.

Staff has adjusted the numbers to account <br /> for the exclusion of fabric-lined landscape beds, retaining walls (out of the 75' setback) and 100 <br /> square feet of deck or patio. At 4,298 square feet or 28%, the property currently exceeds the <br /> allowed hardcover level by 3%. Further, the applicants' proposal appears to result in 0.3% increase <br /> in hardcover and structural coverage. Staff understands the applicants' intent was to balance the <br /> - existing with the proposed hardcover/structure. However we have not received a revised plan and <br /> the proposed levels still exceed the code-allowed hardcover level of 25% (by 498 s.f.) and structural <br /> coverage level of 15% (2,300 square feet); and the proposal also exceeds the existing levels of 28% <br /> hardcover and 18.8%structural coverage by 45 s.f.. <br />
