Our Vision of Beach Restoration and Preservation

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.

Great Highway Lane Closure

As of January 7th, DPW has shut down one of the southbound lanes on Great Highway past Sloat.

I ran down to take a look on the morning of the 9th. The spot that threatens the roadway the worst is just north of the rip-rap over the PUC's outflow pipe. A few smaller rocks at the bottom which neither provide support for the slope nor dissipate much wave energy. Visually, it was not apparent the frequency with which waves could be expected to reach the crumbling cliff. I suspect the agencies involved would want to take some measurements to determine where the cliff is in relation to MLLW and what type of wave run-up would be expected.

There is rip-rap and the remnants a few piles from the construction pier when the outflow pipe was first installed just south of the erosion spot. All in all, the outflow pipe looks well protected, and not immediately threatened. The pavement though, has just a few feet of sandy soil near the edge. It's clear why DPW stepped in and closed down the road.

If any dogwalkers, surfers, or frequent beach users with a digital camera want to take photos, feel free to send them to the email associated with this blog.
