While it naturally comes and goes and storms amplify this, Orient Beach has a losing beach batting average the last 3 years. Climate change/rising seas in the clubhouse or just a natural slump.
As for the sea wall, not sure what else they can do but what they actually did do. Its like protecting a sandcastle with a wall. Eventually you lose.
That is the reality of building on the beach.
To be positive, I'm hoping their batting average changes and they get 3 years of building sand starting right now.
