need to be applied to new development, redevelopment, or existing development that contributes stormwater runoff to these wetlands. Specific recommendations for areas draining to some of these wetlands are included in the RMP. • Other Wetlands — Wetlands that do not have high stormwater impact potential • Wetland Preservation Corridor (WPC) - These corridors form a network of inter- connected natural communities that contain many of the highest priority lake, wetland, and upland resources in the City. They provide the critical foundation for efforts to both preserve and expand the quality and quantity of the wetland, wildlife habitat, and stormwater management functions in the City. An important link between the Comprehensive Plan, Local Surface Water Management Plan, and the RMP is the incorporation of the wetland preservation corridors into these plans and implementing the WPC through RCWD rules and the City's official controls. • Greenway System — These areas represent the portions of the greenway system including in the Resource Management System Plan (further described in Chapter 2) that are located outside the WPC. This is a "working" multifunctional greenway corridor in that it supplements the WPC with additional areas that provide the opportunity for stormwater management, establishing upland buffer areas for wetland protection and wildlife habitat, conservation of natural and semi - natural areas, as well as open space and trails for people. • RMP Project Sites — The RMP identified specific projects sites for ditch management, water quality protection, or volume reduction to implement the RMP. • Sensitive Water Level (Flooding) Points — These points represent areas that are predicted to flood during a very high rainfall event (100 -year storm) given the proposed full build future land use and proposed RMP. Low impact development techniques and stormwater BMPs need to be applied to areas that currently contribute to (existing conditions) or are predicted to contribute to (full build out) flooding at these points. Implementing measures to address flood control at these points is critical to achieving the flood control goals of the RMP. Specific recommendations for addressing some of these points are included in the RMP. The sensitive water level points are grouped into three categories 1. Road Overtops — Areas where flooding goes over the top of a road 2. Less than 1" Freeboard on Road — Areas where flood water levels are less than 1" from the top of the road 3. Stormwater Pond Overtops — Areas where existing ponds can not capture the volume of water runoff from flood events • RMU Outflow Point — Indicates the location where surface water flows out of the RMU and the direction it flows. • Stormwater Pipe — The location of existing underground stormwater conveyance pipes. Since the RMU boundaries are based on subwatersheds and the planning district boundaries are based on sanitary sewer districts, several RMUs are located partially within each planning district. The discussion of each RMU will be located within the planning district that includes the majority of the RMU. The Table 10 -1 indicates the RMUs that are discussed within each planning district. 10 -2 • •
