A photo or a few photos of the existing Ellacoya RV campground, waterfront area, bathroom building, access road, and existing bootleg boat ramp and circular dirt drive would add a lot to this thread.
It sure seems to me that there's a heck of a lot of open and unused area abutting the undeveloped sandy beach that's in front of the rv campground. As it currently exists, the sandy beach has no dock, no paved boat launch access, no accessory building(s), no mooring field, no boats, no nothing except a sandy natural beach. Immediately next door, you have the Lake Shore park residential area which is a lot more thoroughly developed and used. There is a sewerage pumping station located just across the chain link fence, on Ellacoya property, from the Lake Shore Park, which is probably one reason why so much cottage construction, close to one another, was allowed there over the last 125-years (or, something like that
?).
