wetland plant communities and rare animal species found in the RCWD; however, none of these are found in Mounds View. 2.9 LAND USE The land cover characterizing Mounds View historically included prairies, forests, and wetlands; followed by agricultural fields; and the current urban setting. The MLCCS Land Use Classification is presented in Figure 2.5. The City's 2040 Land Use Map is presented in Figure 2.6. 2.10 DRAINAGE SYSTEMS The City's drainage system is divided into ten drainage districts and 44 drainage subdistricts, as shown on Map 1 in Appendix A. Ultimately, all drainage districts within the City flow into Rice Creek through various storm sewer connections and drainageways. The bulk of Mounds View's surface water management system was built prior to 1980. As was the practice at that time, surface water management relied heavily on large diameter trunk storm sewer to route runoff away from impervious areas quickly and discharge this runoff directly into a nearby receiving waterbody. In many areas of the City, the primary means for conveying stormwater runoff is within existing streets. At points where flows from several streets converge, catch basins are installed to route flow into storm sewer. The City's current drainage system resulted from the economic realities prevalent during system construction in the 1960s and 1970s. As such, it does not meet the City's current 5-year storm sewer design standard. However, the system design has not led to any notable flooding problems, due mainly to the gently rolling terrain providing overflows for localized surface ponding and relatively sandy soils allowing surface ponding to infiltrate before impacting adjacent structures. The storm sewer and surface water system in Mounds View are fully constructed to serve the needs of the City. Modifications to this system continue as small parcel infill development, redevelopment, and street reconstruction activities warrant. One challenge for the City as a part of this LSWMP will be to identify locations where the City's existing surface water system can be improved or new features added within existing development or redevelopment projects to enhance and restore the City's water resources. Section 6 of this plan presents an assessment that discusses each of the potential problem areas and corrective actions. 2.11 EXISTING FLOOD INSURANCE STUDIES The National Flood Insurance Reform Act of 2012 and the Homeowner Flood Insurance Affordability Act of 2014 resulted in changes in flood insurance rates. As a result of this legislation, subsidized rates will be phased out over time until structures reflect their true risk based on the actual elevation of the structure compared to the base flood elevation (or the one percent annual chance flood elevation). Flood Insurance Rate Maps (FIRM) for the City were published in 2010. The FIRM shows Special Flood Hazard Areas subject to inundation by the one percent annual chance flood. The City of Mounds View is covered by FIRM panels 27123C0004G and 27123C0005G. These FIRM panels can be viewed at the Map Service Center Page on FEMA's website: http://www.fema.gov/.
