  2. Agenda  Project background and current phase  Watershed planning in Boulder County  County-wide planning activities  Boulder County Coalitions  St. Vrain  Left Hand  Boulder Creek  Plan milestones  County planning team www.BoulderCountyCreekPlan.org

  3. Purpose The Boulder County Comprehensive Creek Planning Initiative is a forum designed to plan the Creek stabilization and restoration process, thus enabling public infrastructure reconstruction, residential rebuilding and private access restoration, and revised floodplain mapping. www.BoulderCountyCreekPlan.org

  4. Flood Recovery Activities Flood Response: Immediate Actions Flood Recovery: Flood Recovery: Short-Term Actions Long Term Actions Focus on infrastructure repair to Further stabilize infrastructure, reduce risk of Focus on infrastructure reconstruction, creek restoration, flood General Focus restore residential access flooding from spring run-off and summer monsoon risk reduction rains • • • Establish Emergency Access roads, Construct temporary Winter Roads Design and Construct Permanent Roads and Bridges Public Transportation construct critical repairs, bridge Infrastructure stabilization • • • Develop Temporary Flood Recovery Issue FRAPs for temporary crossings Issue FRAPs for temporary crossings • • Access Policy and permitting Modify FRAP policy for permitted structures to Conduct engineering to identify floodplain-compatible Private Waterway (FRAPs) remain in place until master plan completion options for bridges and other types of crossings in canyon Crossings areas • Pursue grant funding for restoration of private crossings • • • Engage residents of unincorporated Conduct risk analysis, site identification to Conduct watershed-level master plans on major drainages Boulder County to collect damage prioritize implementation of High Hazard throughout county to identify stream restoration and flood reports mitigation projects (debris removal, bank mitigation projects, programs, and other actions • Creek Recovery stabilization, etc.) Prioritize residential areas with most severe damage, • Implement High Hazard mitigation projects conduct modeling and other analysis to help residents meet permanent access and floodplain development permitting requirements • • • Issue Floodplain Development Issue Floodplain Development Permits Issue Floodplain Development Permits • • Permits Develop recovery maps (CWCB) Conduct regulatory review for ability to meet FEMA Floodplain • Modify FRAP policy to ensure temporary requirements and install permanent crossings Management • crossings can accommodate water flows Incorporate recovery maps and other new data into floodplain management www.BoulderCountyCreekPlan.org

  8. Creek Master Plans Create an open, collaborative, and voluntary approach to long-term recovery and management of the watersheds in Boulder County.  Led by Coalitions  A post-flood watershed analysis, risk assessment, and plan for creek recovery  Coordinated with: Public road and bridge reconstruction  Residential rebuilding, including private crossings  Floodplain management   Funded by the Colorado Water Conservation Board, Boulder County, other local agencies  Property owner and public participation is integral www.BoulderCountyCreekPlan.org
