Golden Gate Case Study

ELASTEC Type III Ruffwater Screen was installed near the Golden Gate Bridge in San Francisco, CA. as part of the Crissy Field Drainage Improvement Project. Duane Bennish and Bill Andrus of the Cocoa branch were on site to help with the installation.

There was an existing drainage pipe that extended out into the water, but over time, the beach widened and the pipe was getting sediment in it and becoming blocked. It was difficult to clean out, so the remedy was to extend the outfall back out into the water.

Extension of the pipe will increase drainage capacity, reduce sand build up, and alleviate flooding issues. A ā€œUā€ shape of curtain encompasses the worksite so that any disturbed sediment will not pollute the surrounding water, wildlife, and marine life. The install was high profile and was monitored by the media, California DOT, and marine biologists. Crissy Field falls under the National Park Service jurisdiction.
