Bay Restoration

The largest coastal wetlands restoration project in the nation is underway in San Francisco Bay.  The goal is to restore 100,000 acres of wetlands.

HORIZONTAL LEVEE® Coastal Storm-Surge Barrier

Restoring San Francisco Bay’s tidal marshes is one of the best and most inexpensive ways to protect valuable shoreline development from sea level rise during the next several decades.

Historic Marshlands

Partially aquatic, partially terrestial, the San Francisco Bay-Delta Estuary marshlands once covered 542,000 acres.

Century of Destruction

By the late 20th century, only seven percent of the original, historic tidal wetlands remained.

Marsh Wildlife

The marshlands were a nursery ground for juvenile fish and habitat for millions of migratory waterfowl and shorebirds.

Turning the Tide

The Bay Institute works with dozens of partners to help restore San Francisco Bay's lost marshlands.

Restoration Projects

The Bay Institute is raising funds and promoting public support to restore 100,000 acres of wetlands.
