Our Vision of Beach Restoration and Preservation

The shorelines of Ocean Beach south of Sloat Blvd and Sharp Park in Pacifica are threatened by rip-rap seawallls and long-term erosion. This blog chronicles our campaign efforts to restore these beaches. Check out the web view of this site to see our proposed solutions and how to help- in the right hand column below. For all the latest about our efforts, see our monthly posts.

We advocate a managed retreat strategy to restore both Ocean Beach south of Sloat and Sharp Park.

At Sloat, our vision involves:

A long-term plan to relocate threatened infrastructure
(including the south of Sloat Great Highway, the two oceanside parking lots and the sewer lines underneath them).

The cleanup of all the rock and rubble littering the beach.

The use of sand dunes as the primary tool to slow erosion.

For Sharp Park, we advocate the decommissioning of the golf course, the removal of the rip-rap berm, and a full restoration of the wetland.

Sandbag Work Complete - Extended Comment Period for Draft OBMP

Dear Surfrider Supporters,

The sandbag work at Sloat's north lot is now complete. Presently, there are no other plans to add sandbags unless we experience an extreme erosion event.

Some folks may wonder what exactly constitutes such an event and when do we get them...

Generally, we get heavy beach erosion when powerful winter storms make a direct hit to our coastline. A direct hit occurs when the core of a system makes landfall bringing with it high surf, strong winds and heavy rain. Here's a little video clip of an erosion producing storm: The worse erosion for us tends to occur when a direct hit coincides with a large high tide, such as those in the 6.0 ft. range or better. Storms barreling in from the ocean can create a powerful storm surge, allowing the surf to advance much further inland than under fair weather conditions. This allows the sea to chew up or erode whatever lies in its path. Most folks have heard of storm urge associated with hurricane landfall. The storm surge that comes from our winter storms is basically the same thing. Though less dramatic, storm surge from Pacific systems can cause plenty of damage, too, especially when structures have been located too close to the sea.

The good news is that this winter, we appear to be safe. The jet stream, which carries our storm activity, has been positioned well to the north. There has been a bonanza of great weather and surf, and a reprieve for the Sloat shoreline.

In other news, SPUR has secured a grant to do the feasibility analysis for the draft proposal at Sloat. This is great news. We hope to see a full analysis of the low profile tunnel reinforcement concept along with a tunnel relocation/re-alignment option. We are particularly interested in cost/benefit issues (factoring in the value of recreation and ecology). Perhaps some combination of approaches may finally emerge. We certainly believe that any long term plan should include a phase in which the tunnel is removed from the beach.

Finally, SPUR has also extended comment period on the draft Ocean Beach Master Plan. If you have not yet added your input, there is still time. Please visit There are a lot of changes being proposed for the entire beach. It behooves all of us to weigh in. Comment period ends February 29th. Thank you!
