It seems to me that eminent domain of a 5 foot wide swath (2.5 feet on each side) would be the best long term solution.
This is the most sensible solution. The 5th amendment clearly assumes the right of the government to take private property for public use as long as just compensation is paid. The 5 foot path isn't enough considering that in the future trucks and firefighting equipment such as bulldozers might need to get through. No need to go through the expropriation process more than once. 50 or 60 feet would be more like it.
Patriotism (and religion) is the last refuge of a scoundrel.
