Unlikely that anything of any real consequence will be found. The sea level rise after the last glacial period took more than 1000 years to complete, so every inch of land between the old sea level and current was AT sea level for an extended period of time. An encampment 100 feet above sea level at the height of the ice age might have been at sea level by the beginning of the Younger Dryas, and would have remained at that level for decades...possibly even centuries when tidal variation is taken into account. Every wave beating on the coast for every minute of every day during that time would have done its part to crush any artifacts to sand.

Because any artifacts would have been left on the surface, the odds of anything surviving the sea level climb are astronomically remote.

Makes a great story, and sounds plausible, but you're terribly mistaken. Most artifacts that have been found have been in remarkable condition - and there are many. Discarded items would have been well buried, only to be exposed by beach erosion, and redeposited beyond the grinding areas of the shoreline in short order. Good try though.
