��na August 12,2015 Page 3 of 8 General Site Characteristics The property slopes downward generally from a central high point toward Tanager Lake to the north, and to a large wetland in the south end. The north half of the property in which the tluee new building lots ate proposed is heavily wooded and contains two defined bluff areas,one on Lot 3,and the other primarily on Lot 4. The existing resiclence sits above the bluffs,�pproxima.tely 70' higher than Tanager Lake; below the bluffs where the proposed new building sites are located, ground e�evation ranges from 10' to 40' higher than the lake, Potential home locations and driveways are shown on the preliminary plat for illustrative pwrposes, although all are subject to revision. The wetlands have been delineaxed but confirmation of their boundaries by MCWD is still pending. A more detailed description of the site chazacteristics can be found in the Conservation Design Report(Eahibit G7. Lot Layout and Lot Standards According to the LR-IA Zoning District standards all of the lots must contain 2.0 dry, buildable acres and meet a 200' width requarement at the shozeline as well as at the 75-foot principal building setback from the lake. The individuallots lay out as follows: Lot 1 Lot 1 conta.uas approximately 3.6 totaJ acz�es, which includes a portion of a linear wetland adjacent to the Dakota Rail Trai.l. The lot is also proposed to contain a stormwater ponding area(near th.e new cul-de-sac), resulting in a final dry buildable area of approximately 3.2 acres. The lot width is 350 feet at the lake,approximately 360 feet at the 7S' lake setback. The proposed house site sits approximately 8 to 12 feet above Tanager Lake, with a driveway extenci.ing S00 feef from the new cul-de-sac. Lot 2 Lot 2 is approxima�tely 2,2 acres in total ares,which includes a small (0.06 acre) wetland centrally located and about 10 feet above lake level. Lot width is 220 feet at the lake and ax fihe 75' setback. The proposed house site is about IS-20 feet above lake level, with a proposed driveway jns�over 30Q �eet in length. Lot 3 Lot 3 is approximately 3.4 acres in area,which includes a 0.04 acre sliver of wetland at the SE corner of the lot. Portions of the southerly half of the lot are bluffs, and the suggested house site sits on a terrace approximately 40 feet above the lake,just above a slope that averages nearly 30%and may be a bluff—this needs to be further analyzed. The proposed driveway extenc�s approximately 275 feet from the new cul-d�sac. Lot 4 Lot 4, with the existing residence and accessory buildings, contaix�s just over 20 acres in total area of which a�proximately 13 acres is dry. Access is and will remain from County Rvad I5. This lot has the potential to be further subdivided in the firiure. The proposed lot boundaries have been configured such that existing house and outbuildings rem$in confomung to setback requ.irements. Lot 4 retains frontage on both Smith's Bay and Tauager Lake. There bias been discussion regarding whether the City wo�d allow a joint use dock serving Lots 1-4 on Smith's Bay, to allow Lats 1-3 to have large boat access to Lower Lake due to the limited clearance of the Tanager Lake bridge ax CR]5 (discussed further below).
