Stantec CENTERVILLE SURFACE WATER MANAGEMENT PLAN PHYSICAL ENVIRONMENT September 2012 (Figure 8) are now one and the same. This is not to say that the Official Zoning Map reflects the existing land use. The Existing Land Use Map is shown in Figure 6. Figures 6 and 7 are taken directly from the Centerville 2030 Comprehensive Plan; Figure 8 is the recently adopted Official Zoning Map. There is no current plan to further alter zoning within the City. The zoning ordinance now classifies land use into eleven categories: Rural Residential (R1), High- Density Single - Family Residential (R2A), Single - Family Residential (R2), High- Density Multi - Family Residential (R3), Single - Family Manufactured Housing (R4), Single Family Residential- Estate (R5), Commercial (B1), Industrial Park (11), Public /Institutional (P1), Mixed Use (M1), Mixed Use Neighborhood District (M2). The zoning ordinance also regulates shoreland activities. Figure 9 delineates the approximate floodplain and floodway boundaries within the City. The City initiated the Floodplain Reduction Project along Clearwater Creek in 1989. This project involved the investment of significant resources to reduce flooding potential along Clearwater Creek. Following completion of the project, a Clearwater Creek flood study was conducted and a Letter of Map Revision (LOMR) was subsequently approved by the Federal Emergency Management Agency (FEMA) in October 1997. As a result, the Flood Insurance Study (FIS), Flood Insurance Rate Map (FIRM), and the Flood Boundary and Floodway Map (FBFM) for the City were revised. These references should be consulted for more complete and detailed information on the floodplain and floodway areas. The current FEMA map is dated June 2, 1999. The Federal Emergency Management Administration has recently acquired more accurate, digitized mapping data and has sent copies of a revised FIRM to cities for review. Centerville submitted several comments regarding areas which have been excluded from the floodplain via LOMA -Fs and other methods. However the resubmitted map did not show these areas out of the floodplain. This map approval process is still in progress at the time of this report. 3.11 GROUNDWATER CHARACTERISTICS Information on the City's geologic and groundwater characteristics, including geologic features, groundwater sensitivity, groundwater discharge and recharge areas, and the influence of land use on groundwater can be found in the City's Wellhead Protection Plan, adopted in December 2007. A copy of this plan can be obtained at City Hall. The plan contains information which the City views as security- sensitive, in an effort to protect their drinking water sources. Therefore, the plan is not available on the Internet, nor should it be attached to this document which will be available to the public. One Team. Infinite Solutions. 3.8 27
