This a very popular beach in the summer. This year the water level where higher then normal. When ever it winder & wavy the sand washed over the road. The town pushes the sand back only to have it go back during the next storm.
Parking that road is not very much (in terms of spots). Thinking about it I would not see a it as problem, but rather the solution. Let it be. If the water will keep pushing it back, close the road to cars (it currently is). There is plenty of parking around it, so losing the spots right by the beach in my mind would be no loss. More beach space for tourists (a large part of the towns economy in summer), it make the bushiness more money.
It be win for the town, & a win for the tourists.
