2013 Flood Response, Recovery, and Post-Flood Mitigation
The CWCB has statutory responsibilities and programmatic capabilities for flood response, recovery and mitigation. Staff will be heavily involved with numerous facets of post-flood action in harmony with local, state, and federal partnering entities.
The following items represent typical work efforts, at a minimum, that CWCB is positioned to carry out in the days, weeks and months to come:
- Supporting the Joint Field Office (JFO) with technical expertise.
- Conducted preliminary damage assessments for Individual Assistance and Public Assistance for the purpose of estimating needs for federal disaster aid.
- Working with Federal-State teams for overall inundation surveys.
- Activated the CWCB Flood and Drought Response Fund to be utilized as leverage for cost-sharing with federal disaster relief funds.
- Provided staffing and agency information at local Disaster Recovery Centers.
- Providing scientific and flood-related data for hydrologic and hydraulic assessments.
- Coordinating with the Colorado Climate Center, Urban Drainage & Flood Control District, and others to help assemble reports on flood-frequency information, precipitation estimates, peak flows, and any forensic H&H assessments that may be needed.
- Communicating with other agencies such as Colorado OEM and DWR on key aspects of flood response and recovery, including water infrastructure needs.
- Collecting data on storm information and related topics for eventual inclusion in a comprehensive flood documentation report, which will help with lessons learned and future mitigation work.
- Comparing actual event data/inundated areas to published flood insurance mapping for ground-truthing and quality control purposes.
- Obtained post-flood aerial photography through emergency air support, in cooperation with multiple local entities, to assist with floodplain assessments and damage photography.
- Partnering, wherever possible, to assist with flood mitigation efforts (ranging from structural solutions, buy-out programs, non-structural flood proofing, insurance education, etc.).
- Coordinating with FEMA on digital flood hazard mapping and NFIP issues such as flood insurance claims and community involvement in the program.
- Updating the task list as the situation requires and as specific needs arise.
- This document demonstrates the severity of rainfall during the 2013 flood event. It is important to emphasize that rainfall frequency does not necessarily equate to streamflow frequency. Factors such as rainfall intensity and areal coverage can result in smaller or larger frequencies in streamflows. CWCB and other agencies will be evaluating streamflow frequencies as information becomes available.
