Public land under threat: Agencies raise alarm about Jupiter Lighthouse area erosion

Historically, the site would lose about two feet of land around the edges each year, on average. Over the past 10 years, that’s gone up to seven feet per year. DeWitt’s concern, from the damage he saw over the holidays, is that the average may go up again, to eight or nine feet per year. At that rate, the historical structures on the site start to look more vulnerable — it would only take about 50 or 60 years at that pace to jeopardize the land holding up the lighthouse.
