Erosion closes one lane of SF’s Great Highway

One southbound lane of the Great Highway south of Sloat Blvd has been closed due to erosion of the bluffs by winter waves, reports the Chronicle:

In 1994, storms took out 30 to 40 feet of the bluff. Then in 1999, after a particularly nasty El Niño winter, engineers opted to build a barrier out of sand dredged from the shipping channel outside the Golden Gate. About 300,000 cubic yards of sand have been dumped offshore every summer since. The "sacrificial barriers give the ocean something to chew on rather than the bluff," Filice said. [...]

City officials are working with the Army Corps of Engineers and the National Park Service to come up with a long-range plan to deal with the erosion.
