This is a link to the regulations that the U.S. Army Corps of Engineers have when it comes to beaches that have been replenished. A snapshot of these regulations shows the section covering parking, where it clearly states,
"Lack of sufficient parking facilities for the general public (including non-resident users) located reasonably nearby, and with reasonable public access to the project, will constitute de
facto restriction on public use, thereby precluding eligibility for Federal participation. Generally, parking on free or reasonable terms should be available within a reasonable walking distance of the beach."
The Deal parking restrictions seem to violate this regulation should it go through.
