California: forget seawalls, oceans are stronger

Forget seawalls and coastal defenses. In the last 50 years, California has seen several potential solutions for its shrinking shoreline. The fact is that there are no good results.


Up and down the California coast, some communities are deciding it's not worth trying to wall off the encroaching ocean.

Roughly 10 percent of California's 1,100-mile coast is armored. However, attempts to curb coastal erosion — a problem expected to grow worse with rising seas fueled by global warming — have mostly been futile.

This presents an issue of whether some coastal developments should stay or go. Surfrider Foundation and other environmental groups support relocation of coastal infrastructure.

Relocation may prove difficult to execute in densely populated coastal areas, however, the executive director of the California Coastal Commission still views it as an attractive option, and one that is far from the realm of "giving up" on coastal lands.
