4. PROPOSED IMPROVEMENTS 4.1 Storm Sewer System Improvements The storm sewer improvements proposed with option #4 involve constructing a storm sewer system along Gibbon Street and 173rd Avenue. The proposed storm sewer system would begin at the low-lying land -locked area along Gibbon Street, north of 173rd Avenue, and would terminate at County Ditch along 173rd Avenue. The purpose of the outlet is to provide positive drainage for this low-lying area in an attempt to minimize groundwater table elevations in the immediate area. This in turn would help to eliminate or reduce the frequency and severity of wet basements encountered y area property owners. Figure 1 in Appendix A shows the scope of the proposed storm sewer system improvements as depicted by the red line segments. 4.2 Watermain Improvements No watermain improvements are proposed. 4.3 Sanitary Sewer Improvements No sanitary sewer improvements are proposed. 4.4 Street Improvements Portions of Gibbon Street NW and 173rd Avenue NW will be impacted by the proposed storm sewer improvements requiring some street repairs. This work will primarily involve removing and replacing portions of existing bituminous pavement, as well as turf restoration. 4.5 Private Utilities Staff will meet with electric, gas, and telecommunication utilities during the final design process for this project as reflected in the project schedule. No impacts to power poles or street lights are anticipated with this project. If a utility company indicates they want to upgrade, replace and/or otherwise modify their services during this project, any such upgrades, replacements and/or modifications will be at the sole discretion and cost to the private utility. 4.6 Permits Permits that are anticipated to be required as part of the proposed improvements include: • MPCA General Stormwater Permit (NPDES) • LRRWMO Permit Feasibility Report Gibbon Street and 173rd Avenue Drainage Improvements City of Ramsey Project No. 16-88 Page 6
