4.4 The Mogg development will require grading of the area where the proposed town homes will lie. The existing parcel slopes southwest into the wetland and upon completion of the grading for the proposed development, the parcel will still slope to the southwest. However, storm water drainage of the joint and individual driveways will require some form of runoff management. The grading/drainage plan for this development will require the approval of the Grass Lake watershed and the Roseville Engineering Department. Based on the proposed grading plan all town home units will be walkout units, 4.5 City sanitary sewer will be extended from the existing line on the south side of County Road C and City water main extended form the north side of County Road C. All utilities are proposed within the driveway and individual service connections to each residential lot being extended from the main line. 4.6 The parcel is located adjacent to a large wetland for which a minimum setback of 50 feet is required. The proposed town homes are set back a minimum of bo feet and as much as 100 feet from the wetland. The northeastern most town home is setback a rninirnum of 30 feet from the property line adjacent to County Road C, while the southeastern most town home is setback a minimum of 28 feet from the east property line, that boundary separating the Mogg parcel from the single family homes along Cohansey Street. 4.7 The Roseville City Code requires new two - family attached units to have a minimum structure setback distance between buildings of 20 feet. The proposed PUD has a minimum structure separation of 20 feet. 4.8 Traffic generation (Source: Institute of Traffic Engineers -- Traffic Generation Manual) is estimated to be from 7 to I I vehicle trips per housing unit or a total of 49 to 77 trips per day which will enter or leave the site during a given 24 hour day. County load between western Avenue and Dale Street had a 2000 ADT (average daily traffic) of 9900 trips per day and is not at capacity for an "cross-community" County road and can easily absorb the added trips (a "trip} is defined as one vehicle entering or leaving a lot). It is estimated that County Road C between western Avenue and Dale Street will have 20 10 A.DT of 13, 100 trips per day and a 2020 estimate of 16, loo trips per day. The road is in the County improvement program, but no date for reconstruction has been set. 4-9 Utility services — City water, sanitary surer} and storm surer have the required capacity in this area to serve the proposed development. 4.10 The attached proposal illustrates the proposed driveway, house pads with structure footprint and driveways, common area* and other improvements.
