In the 1950’s Lake Michigan had a similar problem. Academics at MSU measured the sand volume over time and realized that the amount of sand was receding quickly. So they took on a massive project to plant marram grass all along the lakeshore. This takes several years to mature, however once it does the roots grow deep and the sand stays in place for a much longer period of time. I am not sure what this community can do now, it feels a little too late. Maybe build a temporary sea wall, plant grass to hold the new sand, then remove the sea wall? https://mnfi.anr.msu.edu/communities/description/10714/Sand https://mnfi.anr.msu.edu/communities/description/10714/Sand
