��. 15-3763 July 16,2015 Page 3 of 8 acknowledged in the development appz�oval stage as creating `new existing grades'. No grading of individual pads is indicated an the preliminaty plat drawings. Relationship to Su�-rounding Development The proposed single-faxnily development is consistent with existing development in the surrounding neighborhood. Similar single family lots with 2-plus acre lot sizes exist to the norkt�, while the lots within Kintyre Two to the immediate south range from 1.4 to 3-plus acres. General Site Characteristics The portion o£the property to be developed for new single-family lots is somewhat remote firom surrounding public roads. The properiy slopes downward generally from a high poznt at the southwest to a lazge wetland complex to the northeast and eas� A smaller wetland to tkze northwest will also impact development of the site. The wetlands have been delineated and are depicted on the preliminary plat drawings - MCWD has confirmed the wetland boundaries. The portion of the properties encompassed by the wetland to the east is withi.n the Shoreland Qverlay l�istrict, while the uplands are outside that District The area beiu�.g developed is for the most part open field, with areas abutting the wetlands being woaded. Outlot A, which is an 8-acre portion of the property not proposed for development at this time, is mostly wooded. A more detailed description of the site characteristics can be found in the Conservation Design Report (Eahibit C}. Lot Layout and Lot Standards All 7 lots aze propased to be accessed via a northward extension af Kiniyre Lane, a private road extending from Watertown Road. All lots are proposed to be served with private wells and septic systems. Septic testing has been conducted and the test reports and mound site layouts aze currently under review by the City Engineer (see Ezhibit F). Following is a brief rev�iew of each proposed lot: Lot 1: This lot is shown as having 2.19 dry acres and no wetlands. The lot contains an area of 20% + slopes with more gradual slopes further east. The lot width is just over 200' at the road, 200' at the front setback line, and tapers to 1Q0' at the rear lot line. Primary and alternate dra�infield sites have been tested and are located at approximately the midpoint of the length of the lot. Lvt 2: Lot 2 contains 2.38 acres of which 0.20 acre is a wetland and 0.17 acre will became a stormwater ponding area, Ieaving a dry buildable area of 2.01 acres. Lot width exceeds 200'. The SW portion of�he lot in the azea of the anticipated building site has slopes in the 20% range. The MCWD-required 40' wetland buffer and additional City-required 10' setback from the buffer act to restrict the flexibility in house placement for this lot. Primary and alternate septic sites have been located to just meet all required wetland and lot line setbacks. Lot 3: The lot as proposed contains 2.29 acres of which 0.15 acre is wetland and U.10 acre will be part of the ponding area, leaving a dry hui�dable acreage of 2.04 acres. Slopes at the anticipated house site appear to be in the 5-10% range. This lot meets the 200' width requizement and there should be no problem developing a home meeting all required setbacks.
