<br /> <br />Feasibility Report Page 15 <br />Snelling Avenue North and County Road E - Street and Utility Improvements <br />City Project Number PW 20-0100 DRAFT <br />method of repairing the pipe segments located outside of the intersection by avoiding <br />excavation required to remove and replace the pipes. <br /> <br />Storm water drainage design will need to meet Rice Creek Watershed District (RCWD) <br />requirements as outlined in Rule C. This section of the watershed regulations requires a <br />permit for Public Linear Projects creating 10,000 square feet or more of impervious surface. <br />The project design will evaluate specific Best Management Practices (BMPs) such as bio - <br />filtration and inline sediment/grit chambers placed before discharging into the downstream <br />storm sewer system. Section 5 includes a general cost estimate for these BMP items. <br />Temporary erosion and sediment control devices will be utilized during construction in <br />accordance with applicable NPDES permit and RCWD Rule D requirements. <br /> <br />Private Utilities <br />Construction of a single lane roundabout as shown in Appendix I is anticipated to require <br />relocation of overhead power lines along the west side of Snelling Avenue and may require <br />modification to the natural gas manifold assembly located in the southwest quadrant of the <br />intersection. Early and frequent coordination with Xcel Energy will be necessary during the <br />design process. <br /> <br />3.6 Easements <br />Street improvements south of County Road E as proposed within this report are anticipated <br />to occur within the existing road right-of-way. Public utility improvements are planned to <br />occur within the right-of-way or currently dedicated drainage and utility easements. The <br />need for permanent easement acquisition south of County Road E is not expected to construct <br />the project as proposed. <br /> <br />Construction of the proposed single lane roundabout at the intersection of County Road E <br />and Snelling Avenue North may require temporary and permanent easement acquisition in <br />the southwest quadrant of the intersection from the residential property at 3586 Ridgewood <br />Road and potentially the northeast quadrant at 3610 Snelling Avenue North. The intersection <br />design described in Section 3.4 will involve encroachments into the excess right-of-way <br />green space commonly referred to as Lindey’s Park in the southeast corner of the <br />intersection. A portion of this green space will also be needed for construction of a <br />stormwater BMP to fulfill the regulatory requirements of the Rice Creek Watershed District. <br /> <br />3.7 Permits/Approvals <br />The anticipated permits required for the proposed project are as follows: <br /> Minnesota Department of Health . . . . . . . . . . . . . . . Extension of Water Main <br /> Ramsey County . . . . . . . . . . . . . . . . . . . . . . . . . . . . Right-of-Way Permit <br /> Rice Creek Watershed District . . . . . . . . . . . . . . . . .
