Hi Sean
I am a member in two fields here in Paradise. one here in Venice and another in Ellenton (37 miles away). Both are on landfills with no rent payments (but, I understand, HUGE amounts of politicking involved).
Venice has a 400' X 50' paved RC runway and a 1/3 lap paved CL strip. Good, clean air. The club paid for all of the improvements...including pavement.... There are three sheds (one for mowers, one for generators and other equipment and one that is used for serving food and storage). There are two small-ish solar power stations that provide enough for five or six electric fliers. The club maintains the entire facility. There are about 130 members and the annual dues is $95.00. Contests or other events require rental of an additional outhouse and a fairly expensive permit to serve food. The annual budget is around $10K, with a reserve fund of $1K annually to repair the runway.
The Ellenton facility (Manatee County Radio Controllers) is on an UNCAPPED landfill, meaning that when water "ponds" the local authorities bring lots of dirt and debris in to fill the voids. It is up to the club to make the surface as smooth as possible. The MCRC has a 500' X 150' grass runway as well as a 120' X 10' concrete take off pad for UC. Although no rental fee is paid, the club is responsible for all upkeep, and the club has a fleet of equipment stored in three steel containers. The MCRC has a double wide mobile home (actually an old temporary school building) with separate men's and ladies rooms, running water and heat/AC. There is also a "Pilot's Den" that has hot water/full electric and is used for serving food at events and at monthly meetings. There are 8 sheds along the RC flight line and another at the UC area that are fully electrified. There are around 100 members and the annual dues is $100. The budget is very close to annual dues intake, but there is a little in reserve for emergencies....
The politics of obtaining a suitable site are slow and difficult, at best. Rich Giacobone and I (and others) spent a decade trying to obtain a permanent site in Bergen County, NJ, to no avail......we were awarded several temporary sites, the best being the Palisades Park swimming pool site, which we used from Labor Day to Memorial Day.
Have fun!
