As you <br />are aware, this is the approximate two-acre parcel property located in the southeast quadrant of Twin <br />Lakes Road and Sherburne County Road 12. The proposal is to construct nine townhomes, a four- <br />unit building and a five-unit building, on the property. The submittal consisted of a preliminary plat <br />and site plan, preliminary utility plan, and preliminary grading and drainage plan. The submittal <br />package was prepared by Otto and Associates Engineers and Land Surveyors, Inc. Based on our <br />review, we would offer the following comments: <br /> <br />The preliminary plat for Boulder Point should provide access control on all sides, with the <br />exception of the driveway area, which connects to Vance Circle in Trott Brook Farms <br />South subdivision. <br /> <br />Sanitary sewer and water service are proposed to be provided by extending utilities from <br />Vance Circle in Trott Brook Farms South. The sanitary sewer and water will be considered <br />public improvements, and therefore need to be constructed within drainage and utility <br />easements to allow operation and maintenance of the sewer and water facilities by the City <br />staff. <br /> <br />Unless'there is an association that will be billed directly for the sanitary sewer and water <br />service, each individual lot, if individually owned, needs to have its own services. <br /> <br />There is an existing curb cut on County Road 12 for the driveway to the existing home on <br />the site. The driveway needs to be removed and the concrete curb and gutter replaced <br />with barrier-style curb at the opening in County Road 12. <br /> <br />No storm sewer calculations were submitted with the plans. Storm sewer calculations will <br />need to be provided, reviewed, and approved. Currently, the drainage plan is showing <br />catch basins and storm sewer collecting runoff from the site and conveying it directly to the <br />holding pond in Trott Brook Farms South. The holding pond in Trott Brook Farms South <br />was not sized for the development of the Boulder Point. The pond will need to be enlarged <br />to accommodate the drainage from Boulder Point, such that outlet from the pond to the <br /> <br />Ltro091003-Harlicker <br /> 1326 Energy Park Drive · St. Paul, MN 55108 ° 651/644-4389 fax 651/644-9446 toll free 888/368-4389 <br /> <br /> <br />
