be constructed to adequately service the street and whether they should be brought up to the size and configuration indicated by the Comprehensive Storm Drainage Plan. If the inclusion of water quality and quantity control facilities is not feasible, as determined by the City Engineer, when street reconstruction occurs, off-site mitigation may be considered regionally as proposed within the Comprehensive Storm Drainage Plan to meet the City’s storm drainage requirements as determined by the City Engineer. CF-47 The City shall require the separation of sanitary and storm sewer facilities wherever combined sewers may be discovered. CF-48 In selecting the preferred Comprehensive Storm Drainage Plan sub-basin alternative for implementation by the City’s storm drainage utility, the City shall consider the following factors: 1. The most efficient and cost-effective means of serving a sub-basin or combination of sub-basins 2. The ability of the alternative to implement source control best management practices and to avoid or mitigate environmental impacts, such as impacts to existing wetlands, and the degree to which the alternative promotes water quality treatment, and protects aquatic and riparian habitat 3. Consistency with Comprehensive Storm Drainage Plan policies and recommendations and compatibility with stormwater improvement policies and recommendations presented in other regional stormwater plans 4. Restrictions or constraints associated with receiving waters 5. The ability to develop a multiuse facility 6. The degree to which the alternative preserves, increases, and is compatible with existing open space

7. Consistency with existing and future planned development 8. The advantages and disadvantages of storage versus conveyance while ensuring adequate treatment for water quality treatment 9. The degree to which the alternative preserves and enhances existing native vegetation and existing drainage courses 10. The alternative’s effectiveness at reducing the flood hazard impacts that would result from the 25-year-design storm event CF-49 The City’s storm drainage Utility shall strive to meet the environmental protection goals of the Comprehensive Plan through compliance with and implementation of the policies contained herein. Environmental issues such as water quality and fish habitat protection shall be considered in all new development applications and new storm drainage improvements. CF-50 The Storm Drainage Utility shall work with other jurisdictions and agencies to address regional water quality issues. CF-51 The City shall seek opportunities, where feasible, to reintroduce treated urban runoff back into the groundwater system as new development and redevelopment occurs in order to minimize urbanization impacts to the hydrology of natural river systems. CF-52 The City shall evaluate the feasibility of improving the water quality of its existing discharges into river systems, in order to enhance water quality in response to the Endangered Species Act. CF-53 The City shall seek to minimize impacts to natural river system hydrology by encouraging pretreatment of surface flows from new development, and reintroduction into groundwater, where feasible.
