Erosion of Our Nation's Coastlines: Surfrider Chapters Fight to Preserve Our Beaches
Greetings Surfriders and Friends,
While we await the next opportunity to press our case for restoring the Sloat and the Sharp Park area shoreline, we thought it would be a good time to check in on other erosion campaigns led by the Surfrider Foundation (see links below).

Nearly all the campaigns share a common story-line:
Shoreline development is built without respect for the consequences of long term erosion patterns. When the surf zone eventually threatens such development, the first reaction is to place revetments or sea walls to be used as defense. At a certain point, when the beaches become almost entirely submerged, sand nourishment projects are used.
Usually, the armoring and sand replenishment projects buy time, restoring the beaches for a limited period. However, eventually the sand and/or shoreline access disappears under the ever encroaching surfline. A crisis or emergency typically occurs when a large storm moves in, wipes out the beach, and brings a new round of damage to remaining structures.
As we know, this just reignites the cycle. New, "improved" armoring/beach nourishment projects are built that end up with the same result - limited, short term success at high cost. Unfortunately, more than a few of these armoring/nourishment sites have also threatened the quality of our surfbreaks.
We say it is time to update coastal zoning plans so as to spread the use of long term strategies based on managed retreat. With long term planning that allows for shorelines to migrate inland, we can both preserve the integrity of our nation's coastlines and avoid a parade of expensive engineering projects.
