a ntec CITY OF CENTERVILLE -2018 LOCAL WATER PLAN of the SWPPP (effective August 2013) is included in the Appendix, attached to this Local Water Plan. 6.9 WETLAND MANAGEMENT In accordance with the Minnesota Wetland Conservation Act (WCA), the RCWD currently serves as the Local Government Unit (LGU) for WCA administration within the City. The City anticipates that the RCWD will continue in this role in the future. Chapter 5 of the RCWD 2010 Watershed Management Plan delineates the details of the watershed district's wetland policies. These policies govern all wetland management issues within the City. As with floodplains and stormwater facilities, all wetlands within the property limits of new developments must be covered by protective easements. Any construction activity that may impact wetlands may require permits from the RCWD, the US Army Corps of Engineers, and/or MnDNR. Correspondence regarding any wetland impacts should be directed to the following: MN Dept. of Natural Resources US Army Corps of Engineers Jason Speigel, Area Hydrologist Andy Beaudet, Anoka County Point of Contact 1200 Warner Road St. Paul District, 180 5th Street E., Suite 700 St. Paul, MN 55106 St. Paul, MN 55101-1678 (651) 259-5822 (651) 290-5642 Rice Creek Watershed District Nick Tomczik, Permit Coordinator/Wetland Specialist 4325 Pheasant Ridge Drive NE, Suite 611 Blaine, MN 55449 (763) 398-3079 6.10 FLOODPLAIN ADMINISTRATION Flood damage prevention requirements are contained in City Code Chapter 155 (see appendix). The goal of the requirements is to promote the public health, safety, and general welfare and to minimize the potential impacts of flooding such as loss of life, loss of property, disruption of commerce and governmental services, and extraordinary public expenditures for flood protection and relief. Figure 7 illustrates the approximate floodplain boundaries within the City. In February 2016, Houston Engineering produced a report for RCWD, entitled, "Future Land Use Conditions Hydrology & Hydraulics Analysis for Upper Rice Creek". A copy of this report can be obtained from the RCWD. The purpose of the hydraulic modeling completed as part of this project was to improve the District's understanding of rate, volume and timing of water movement through the Rice Creek Watershed. This report identifies increases in flooding of lots adjacent to JD3 in the City of Centerville. The model results indicate that there are more substantial increases to smaller storm events (2-yr, 24-hr) than larger storm events (10-yr and 100-yr, 24-hr). As the City develops lots adjacent to JD3 that are identified in this report, it may 27 122
