<br />FEASIBILITY STUDY <br />FOR <br />HUNTERS CROSSING <br />Street and Utility Improvements <br />File No. 616-00-114 <br /> <br />INTRODUCTION <br /> <br />This Feasibility Report is for the construction of sanitary sewer, water main, storm sewer <br />and streets to serve Hunters Crossing. As shown on Figure 1, this 37-lot residential <br />subdivision is located on the west side of Centerville Road (CSAH 21), approximately <br />700 feet south of Center Street. The property is bounded by CenterviIIe Road on the east, <br />Lamotte Park on the north, St. Paul Water Utility/Lino Lakes on the west and the <br />Wilharber property on the south. Richard S. Carlson and Associates is developing the <br />22.74-acre parcel. This report includes descriptions of the proposed improvements, cost <br />estimates, timetables, easements, permits, assessments, and detailed drawings. <br /> <br />PROPOSED IMPROVEMENTS <br /> <br />Sanitary sewer and water main to serve the project are located several hundred feet north <br />of the plat, and will need to be extended along either side of Centerville Road. Since <br />Hunters Crossing is located outside the MUSA (Metropolitan Urban Service Area), the <br />developer will need to request an extension from Met Council. Approval of the city <br />Comprehensive Plan Amendment (PUD) is necessary. <br /> <br />1. SANITARY SEWER: <br /> <br />A deep trunk sanitary sewer exists on the east side of Centerville Road at Center Street. <br />It is proposed to connect to a manhole at this location and install 12-inch diameter pipe to <br />the south, as shown on Figure 2 at the back of the report. The pipe would be jacked <br />(tunneled) under the county road at Center Street, then extended south at minimum grade <br />approximately 700 feet to Hunters Trail. It is proposed that the 12-inch pipe would be <br />extended 400 feet further south for future sewer service along Centerville Road. Services <br />to two existing homes on the west side and two homes on the east side of Centerville <br />Road would be provided off the trunk line. Service lines under CSAH 21 would be <br />tunneled to prevent disruption to the pavement. <br /> <br />Within the development, 8-inch diameter pipe would be extended along centerline on <br />Hunters Trail and the two cul-de-sac streets. The sewer would extend to the end of the <br />stub street at the southwest comer of the plat. This appears to be the high point in the <br />area, and the sewer could be extended to several homes in a future plat to the south. Four <br />inch diameter service pipe would extend 10 feet past the right-of-way line for each lot. <br /> <br />2 <br />
