Disclaimer: Information about the Whittier Narrows Dam Safety Modification Project is constantly evolving and subject to change based on project updates from the USACE.

Project Need

Beginning fall 2021, the U.S Army Corps of Engineers (USACE) will begin construction on the Whittier Narrows Dam Safety Modification Project (Project). Repairs to the dam are expected to be completed in 2026.

The USACE has determined that the Whittier Narrows Dam poses a very high risk of failure thereby exposing 25 cities and up to 1.1 million people to potentially catastrophic flooding. As a result, the project has elevated to a critical state of urgency. The proposed improvements will prevent the significant loss of life, damage to property, and major economic and environmental consequences. Learn More

Project Impact to Pico Rivera

While the Project is essential to the health and welfare of millions of people, it also has significant impacts on the Pico Rivera community. In addition to typical construction-related impacts such as noise, vibration, and dust, the City will lose approximately 67% of its parks, open, and recreation space. The Pico Rivera Golf Club, Streamland Park, Bicentennial Park and Sports Arena Drive/Rooks Road will be closed indefinitely. The fate of the Pico Rivera Sports Arena is still unknown.

The City of Pico Rivera launched this dedicated website, WNDamProject.org, to inform the public. City staff will make regular updates to this website as the USACE provides up-to-date information. Learn More

City’s Efforts to Mitigate Impacts

The City will continue collaborating with the federal government to advance this project while simultaneously addressing its major impacts. The City of Pico Rivera is partnering with vested stakeholders to develop and implement a strategic, yet comprehensive mitigation program.  The City encourages residents to use this website to share their comments and concerns. We welcome all suggestions and ideas to help formulate a vision for the future of Pico Rivera. Thank you for your patience and understanding while the USACE completes the Project.  Learn More
