Stantec CITY OF CENTERVILLE -2018 LOCAL WATER PLAN WATER RESOURCE MANAGEMENT OBJECTIVES AND POLICIES Objective 1 Reduce to the greatest extent possible erosion and sediment deposition from new construction sites into natural water resources within the City. The City experienced significant development in the early to mid-2000s. While development has slowed considerably the past several years due to the economic downturn, it is likely to pick up again in the future. While it may not reach the level of the "boom years", development could continue in the City for several years into the future. To meet this objective, the City will implement a local program of erosion and sediment control that would be administered in addition to the RCWD permit and inspection program. The City realizes that RCWD efforts in this area are limited by manpower and budget constraints, and understands that erosion and sediment control can be better enforced at a more local level. The City understands its responsibilities as an MS4 city. However, there are likely places where the RCWD and the City could work together to eliminate redundancies. Centerville will work with the RCWD to do so. Related Policies (a) Continue enforcing the City code addressing erosion control for all new development occurring in the City (see appendix). Objective 2 Minimize potential damage from flooding of personal and public property. Flooding damages have long been a concern in the City due to the numerous wetland areas and the Clearwater Creek Ditch System. Moreover, flooding problems have resulted from the difficulty associated with maintaining proper drainage over the flat topography of the area. The City has been proactive in reducing flooding potential to residents. For example, in 1989, the City initiated the Floodplain Reduction Project along Clearwater Creek. This project involved the investment of significant resources to reduce flooding potential along Clearwater Creek. It was completed in 1994, with final approval from FEMA of the revised flood profile occurring in 1996. In 2015, the City worked with FEMA to updated the FEMA Flood Insurance Rate Map (FIRM). This map relies on updated LI DAR data to establish a more realistic and accurate floodplain. The FEMA FIRM map is attached (Figure 9). 5.16 54
