Surfers Journal Endless High Tide


The Surfer's Journal, long time literary compendium of surfing lore, recently featured an article on the potential impacts of Sea Level Rise on surfing, including a nice mention of the Surfers' Point Managed Shoreline Retreat project in Ventura.





"For coastal dwellers, possible responses to sea level rise fall under two main categories: coastal armament or managed retreat. Unfortunately, we’ve most often chosen the former as our fix, a choice that’s done more harm than good. 

I grew up at Surfers’ Point in Ventura, and it provided a clear example of the dramatic contrast between the two approaches. In 1986, the dirt parking lot was paved over, and a bike path was built. Just five years later, the concrete was already crumbling into the ocean and the city was considering armament—rocks or a seawall—as an emergency fix.

Coastal Engineer and activist Paul Jenkin, the Surfrider Foundation, and other groups instead fought for managed retreat. ...

After a decade, Jenkin and company won. The pavement was moved 80-feet inland, the beach was replenished with local sand and river rock, and native vegetation was restored. Erosion has all but stopped, even during the El Niño winter of 2015/2016, when, according to a study by the USGS, California experienced beach erosion 76 percent higher than normal.

The lower part of the point, in contrast, shows how poorly coastal armament works. That area has a large paved promenade and seawall, topped with a high-rise hotel and three-story concrete parking garage. During the El Niño winter mentioned above, it suffered major damage, and the city placed jetty rocks along its base, doubling down on coastal armament. The rocks, however, reflect wave energy—creating backwash, increasing erosion, compounding currents on neighboring beaches where erosion is intensified, and disrupting the cyclical sand replenishment that comes each summer."
