a ntec CITY OF CENTERVILLE -2018 LOCAL WATER PLAN maintained at or below existing conditions. The RCWD rules require the infiltration and/or retention of the runoff volume as described in Section 6.1. The combination of these factors leads to a net reduction below existing conditions for discharge leaving the City and entering Lino Lakes. 6.8 EROSION AND SEDIMENT CONTROL Recognizing that erosion and sediment control can best be administered on a local level, the Centerville City Council discussed methods and policies that can be implemented to control erosion from new construction sites. In the past, this responsibility was delegated almost fully to the Rice Creek Watershed District. However, due to the number of construction projects the RCWD administers during a given construction season, it is difficult for the watershed district to inspect these projects. The erosion and sediment control criteria for new developments that resulted from these discussions with the City have been consolidated into an Erosion and Sediment Control Policy for New Developments. The policy adopts the procedures and recommendations of the Minnesota Pollution Control Agency's Protecting Water Quality in Urban Areas: Best Management Practices for Minnesota. City Code Chapter 157 addressing Erosion Control is provided in the appendix. To prevent soil erosion into surface water systems, RCWD requires a District permit where soil disturbance or removal of vegetative cover affects one acre or more of land, or where soil disturbance/removal occurs on 10,000 square feet or more of land if any part of the disturbed area is within 300 feet of any lake, stream, wetland or ditch. Erosion and sediment control plans must: 1) address erosion and sediment issues during and after project completion, 2) be consistent with the MPCA's document "Protecting Water Quality in Urban Areas," 3) minimize the removal of vegetation, and 4) must protect facilities used for post-construction stormwater infiltration. The RCWD has encouraged the City to participate in the District's Water Quality BMP Cost-Share Program. This is a dedicated cost-share grant program to assist property owners with the implementation of Best Management Practices (BMPs) aimed at improving the quality of surface waters within the District. Installing a rain garden, stabilizing erosion problems along shorelines, restoring degraded wetlands, installation of agricultural BMPs, and installing pervious pavers are some of the practices that may be eligible for this program. For selected projects, the RCWD may provide funding up to 50% of total project costs up to a maximum of $5,000. If a project is deemed to be highly beneficial to local water resources, then the RCWD can fund up to 75% of eligible materials and contracted labor up to $7,500. It is important to note that this policy is not intended to eliminate or reduce RCWD inspection efforts within the City; rather, it would be a local means of enforcing erosion control issues with the same primary goals as the RCWD— protection of natural water resource systems. In addition to the discussed regulatory controls relating to erosion and sediment control in the City, the City is a Phase II Municipal Separate Storm Sewer System (MS4) community. A copy 26 121
