Topanga Lagoon sits at the mouth of Topanga Creek, draining from a relatively non-urbanized watershed in Malibu. This small, 1-acre lagoon bordering the Pacific Coast Highway has experienced substantial urbanization pressure. At the same time, the adjacent beach is an important recreational resource for millions of visitors per year. The Topanga Lagoon Restoration Project aims to restore ecological values of the lagoon and preserve recreational value and coastal access, while also building its resilience to climate change. This project, lead by California State Parks, the Resource Conservation District of the Santa Monica Mountains, Caltrans, and Los Angeles County Department of Beaches and Harbors and funded by the California State Coastal Conservancy, will expand the Topanga Lagoon from 1 acre to 7-10 acres and reconstruct an existing PCH bridge to accommodate the wider lagoon.

Community Engagement

California State Parks and the Resource Conservation District of the Santa Monica Mountains are seeking public input on the proposed restoration of Topanga Lagoon and the efforts to protect and enhance its biological, cultural, and recreational resources.
