Rehabilitation of coastal areas has accelerated at unprecedented rates over the past decade.
Since 1969, the surface area of San Francisco Bay has grown by nearly 19,000 acres - a result of policies discouraging bay fill combined with rehabilitation projects that have restored wetlands all across the region. Remarkably, after a century characterized by bay fill, the 21st century has been quite beneficial for the Bay and its surrounding ecosystem with nearly 90 percent of those acres being restored since 2000. In particular, restoration projects in Sonoma County, Marin County and Solano County have played a key role in improving the Bay ecosystem during this time period. In an era of rising tides, these wetland buffers may prove critical in helping the region adapt to global climate change.

BCDC defines the change in Bay acreage as "ocean area of the Bay created or restored, including salt ponds converted into tidal action, less the area of the Bay authorized to be filled pursuant to major permits and major consistency determinations through 1987." This definition includes any administrative amendments to the data.
