This is Leydon v. Town of Greenwich all over again. Read that case and go directly to the Ct. State Attorney General like we all did with the Bantam Lake boat launch issue where the state lost the lease to the state boat launch and the Town of Morris turned the launch into a town-only launch. We challenged that saying that non-residents must have access and the state's AG (Blumenthal at the time) ruled that the Constitution's 1st Amendment right to assemble guaranteed the right to use the Town of Morris Bantam Lake boat launch. Equally egregious is limiting access through unreasonable fees (economic barriers) or restrictive physical access (rock barriers blocking off parking), etc.
What the Beach Association is attempting to do here is to say that there is access to the public but it just isn't as robust as it was before but it is enough. This is similar to the Lake Waramaug strategy where instead of a deep water boat launch at the State Park where dozens of boats could launch and park the lake community lobbied the Governor (Rowland) for a special deal where the DEP would give the Town of Washington 100,000 dollars to expand the town boat launch (six more parking spots, limited hours, public access with boat washing pre-requisite) and allow the public to use it under egregious restrictions in lieu of the double wide deep water launch at the State Park with a 100 acres of field parking areas.
This is all designed to limit access. Go to your local legislatures and the AG and file a grievance.
