<br />Lot Coverage <br /> <br />Since the new garage would be constructed on existing impervious surface, the overall total <br />lot coverage would not significantly change. For the purposes of these calculations, Staff <br />used the 13,939 square foot number for the lot size. The current lot coverage is at 34 percent. <br /> <br /> Lot Coverage <br /> Existing Proposed <br /> SQuare feet % snuare feet % <br />Structure 2206 15.8% 2814 20.2% <br />Driveway 1280 9.2% 673 4.8% <br />Patios 842 6.0% 842 6.0% <br />Other Impervious <br />Surfaces 408.7 2.9% 408.7 2.9% <br />Total Non-structure <br />Impervious Surfaces 2,530.7 18.2% 1,923.2 13.8% <br />Total Impervious Surface <br /> 4,736.7 34.0% 4,736.7 34.0% <br />Lot Size 13,939 13,939 <br /> <br /> <br />Setbacks <br /> <br />The existing structure does not encroach on any setbacks. As noted above, the proposed <br />garage would encroach 20 feet into the front yard setback ifthe variance is approved. <br /> <br />Structure Height <br /> <br />The existing dwelling does not exceed the 35 foot height limit, and the proposed garage <br />addition would not cause the structure to exceed the 35 foot height limit. <br /> <br />2. Flood Plain, Wetlands, and Easements <br /> <br />The proposed garage addition is outside of any flood plains, wetlands, and easements. <br /> <br />3. Additional Review <br /> <br />The City Engineer reviewed the proposal and noted that standard engineering practice for <br />new residential developments would limit driveways to no more than a ten percent grade <br />wherever feasible. The City Engineer and I visited the neighborhood, and there are a few <br />other driveways along Arden Oaks Drive that appear to exceed a ten percent grade change. <br /> <br />City of Arden Hills <br />Planning Commission Meetingfor May 2, 2007 <br /> <br />\lMetro-inet.us\ardenhillslPlanninglPlanning Cases\2007107-012 Muller Variance (PENDING) \050207 - PC Report - Muller Variance.doc <br /> <br />Page40f8 <br />
