Virginia Beach, which does have a sea coast gets no flooding from the ocean and the beaches are 2-3 times wider today than they were when I moved here.

They pump sand up onto the beach every winter.

In the winter time, and for that matter during hurricane season, the waves generally have more energy and will winnow the beach sediments, moving the sand offshore below the wave base. When things are more calm in the summer, the sand grains get moved back onto the beaches and life goes on.

I noticed that hunting for old bottles in the tidewater where I grew up, and some of the most miserable weather (windy, cold, reverse storm surge, spring low tides) was the best for finding 'stuff'.

You're right, but the height of the sea wall doesn't change. And it's the same level now that's it's been for years. I made the point about the width of the beach because the loons crying sea level rise point to beach erosion as proof of their claim.
