The Contra Costa County Flood Control and Water Conservation District recently began a program to evaluate what is needed to provide sustainable flood protection for the entire County far into the future. The District reviewed its flood protection infrastructure in order to better understand its history, condition, and future needs.
Their findings are:
- The 79 miles of flood control channels and 29 detention basins and dams installed since the District’s formation in 1951 represent over $1 billion of infrastructure which protects $25 billion worth of community resources. Over 80% of this infrastructure cost was paid for with federal and state matching funds.
- About 40% of District infrastructure will be over 50 years old in 2020 and is nearing the end of its 75 year service life. Condition assessments, service life analysis, and preservation programs need to be done.
- It is estimated that $2.4 billion in future dollars will be needed to rehabilitate and replace the infrastructure prior to it failing. There are no federal or state programs to meet this funding need and local funding entirely from county residents is not affordable.
- The District needs to develop focused action plans which will better define the infrastructure sustainability issues it faces and recommend solutions. Implementation of the recommended action plans and assessment studies over the next fifteen years will potentially cost $10,000,000 to be funded by existing District programs, with an effort to offset expenses with grant funds. These efforts will be developed in partnership with the communities they serve.
The District is presenting this information in a report to the Board of Supervisors on November 5, 2013 entitled “2013 Status of Flood Protection Infrastructure.” This will be followed at 1 pm with a press informational event in Rodeo at the intersection of 1st Street and John Street. More information is in the documents below.
These actions are timed with the State’s flood protection education and awareness campaign culminating with California Flood Preparedness Week, held November 4 – 9, 2013. For more information, visit the State DWR web site: http://www.water.ca.gov/floodsafe/ca-flood-preparedness/fpw_home.cfm.
