LLC question for RV park

[Mike Reynolds]

I have four lots I want to build an RV park on the water. The guy that has the neighboring lots has contacted me about going in together and making a bigger lot. There are two lots owned by the county that we could get a long term lease beside our lots. This would essentially give us the land from East Galveston bay to the hwy. 

Is it possible to structure an LLC just for the RV park and not include the land? My concerns are this. My part is on the water while his is in the middle. I have no problems with trust of the potential partners as of right now. They are good honest people I have known for years. It's if they ever sell their part I don't want my water front property to be fractionalized by someone else.
