The Army Corps of Engineers Los Angeles District and Regional Planning and Environmental Center are seeking public comments on the draft 2026 Sepulveda Dam Master Plan. This draft is a revision of the 2011 Sepulveda Dam Master Plan and proposes updated classifications to federal lands within the Sepulveda Dam Flood Control Basin, outlines updated management and resource goals, describes the Flood Control Basin’s ecological, environmental, demographic, and recreational context, and responds to comments received from the initial public comment period. All members of the public are encouraged to submit written comments and suggestions by Oct. 30, 2026.
The Master Plan is intended to serve as a comprehensive land and recreational management plan with a life span of 25 years. It guides the stewardship of natural and cultural resources and the provision of outdoor recreation facilities and opportunities to ensure sustainability of federal land associated with Sepulveda Dam.
A presentation outlining the changes, the map book showing proposed land classification and associated changes to previous land classifications, and the revised Master Plan and Environmental Assessment are scheduled to be posted to this webpage Sept. 16, 2026.
Comments must be submitted in writing by Oct. 30, 2026, and can be sent via email or physical mail. USACE will accept written comments in any standard format (such as an email message or a physical letter). Please clearly specify “Sepulveda Dam Master Plan” in your submission.
