We will be looking at land to build a home on across the street from a resevior. I am wondering if we will be able to have a conrete basement for a foundation (does the land have to have a certain elevation above water level) or if we would have to build a slab. Also, if anyone knows, how deep should a well be in order not to get pollutants from public use of the resevoir. Thank you. ***any other advice from someone who has a home near a large body of water would be greatly appreciated!
