Emergency Action Planning

Newly enacted law contained in Senate Bill 92 requires emergency action plans (EAPs) for all dams that do not have a low downstream hazard potential, as determined by the Department. The full text of this new law can be found at: Information related to our downstream hazard potential rating criteria is provided within the related links at the upper right corner of this page.

In accordance with Division 3, Part 1, Chapter 3, Article 6, Section 6160 and 6161 of the CA Water Code, DSOD has authority to require approved EAPs for all dams, except those classified as low hazard. DSOD is responsible for the review and approval of inundation maps while the California Office of Emergency Services (Cal OES) is responsible for overseeing the review, approval, and ongoing activities associated with EAPs under Government Code Section 8589.5. Frequently asked questions regarding EAPs can be viewed at the Cal OES website. In addition, questions regarding EAPs can be sent to the following email address:

EAPs are an important component of an effective dam safety program since they help guide the response during serious dam incidents that could endanger downstream life or property, in the event of an uncontrolled release or failure. Once developed, the EAP should be regularly updated and exercised.

The following links contain information from the Federal Emergency Management Agency (FEMA) and also a sample EAP created by DSOD and Cal OES to give guidance on emergency action planning and dam safety.
