I should have thought of this:
Long time residents reminded me that just a few years ago a similar idea was shot down, but in retrospect it would have been the right way to go!
Build a walking/bike path on the sand between the dunes and the water (that is a wide-and-getting-wider piece of real estate), starting on the north end at Sunset Park and going to the east end of the Shores (the tower condo buildings) where there is a traffic light allowing pedestrians and bikers to cross the Strand Highway and continue on around the island.
Cheap and easy to do. No wrecking Ocean Boulevard. Provides beach access to people who just want to walk and ride along the ocean, but at a good distance not to interfere with swimmers and sun bathers. Might take some work with the Coastal Commission, but could be done.
Memo to the new Council: Please, revisit the Ocean Boulevard plan before it is too late to make a messy mistake.
