1998. Colorado Flood Hazard MitigBtion Plan (4091 with federal and state agencies in the Colorado Hazard Mitigation Team process is crucial. Recommendations on alleviating or eliminating a repetitive problem often focus in local assessment as to the cause of damage and depend on a local applicant for implementation. 3.3.3.1 Local Government Hazard Mitigation Plans Since 1983, local governments requesting state assis- tance for relief of flood damages have been asked by OEM and CWCB to prepare a flood hazard mitigation plan for their jurisdictions. This is a logical extension of the mitigation planning process initiated on a na- tional scaie by the federal govemment. A carefully made plan can be an extremely valuable resource to formulate annual work programs, budgets and policy positions. As a result of the snowmelt flooding on. the Westem Slope in 1984, the CWCB began a program designed to bring the mitigation process to the local level where it will have the greatest benefit. Each applicant for disaster relief assistance was asked to develop a flood hazard mitigation plan tailored specially to the com- munity. A suggested plan outline and a detailed questionnaire were developed by the CWCB to assist in this process. The purpose of such a pian is to articulate those specific local issues which, If resoived, would help reduce Mure flood damages which will have an im- pact on the community. Those locai issues, in tum, could aiso provide the basis for input to the statewide annual mitigation program review. Several Colorado local governments have prepared hazard mitigation plans before and after flood events (see Appendix C for more information): . City of Manitou Springs . Montrose County . City of Boulder . City of Arvada . San Luis Valley . Town of Lyons . Town of Jamestown . City of Canon City . City of Rifle . City of Fort Collins . City and County of Pueblo . Town of Silverplume . Town of Georgetown . Town of OeBeque . Town of Waltenburg 3.3.3.2 City of Fort Collins Hazard Mitigation Planning Land-Use Planning The City of Fort Collins Storrnwater Utility conducts studies on channel stability and delineation of erosion buffer zones along certain channels. The purpose of these studies is to: 1) characterize the stability of the stream on the basis of evaluation of hydrologic, hy- drauliC, geomorphic, and sediment transport charac- teristics of the stream basin and develop practical improvements for mitigating adverse impacts on the streams; 2) develop design criteria and construction standards for improvements in drainageways, with regard to reach stability, within the City of Fort Collins; and 3) establish erosion buffer zones to restrict devel- opment along the floodplain. This will help to mitigate the effects of flooding along unstable reaches of the stream. The Stonilwater utility has a . Waletshed Approach# to address environmental impacts associated with uriban runoff. This integrates water quality mitigation with water quality control in the City's watersheds. Mitigation objectives include: preventing the introduc- tion of environmental pollutants onto iands within the watershed; treating runoff contaminated by urban land uses in the tributary system; and protecting receiving waters riparian, wetland, and aquatic habitats from deterioration. Advanced Planning ACtivities The Storrnwater Utility has a City Plan that establishes core community values, an overall vision, and broad planning goals to the year 2015. This plan addresses city structure, principles and policies, land-use code, as well as implementation procedures. The Storrnwater utility has developed and maintained Master Drainageway Plans for all streams within the I Uriban Growth Area The plans specifies the regula- tory flood elevation dsta as well as mitigation plans to address flooding problems (more information is dis- played in Appendix G, Figure 13-4, page 13-12). .
