Yeah, just read all of it and contacted my contractor, dont think the pics will be necessary. They have construction grade fabric at their shop and we'll use the 10-12" of excavated dirt for the sand recess to make our berm underwater to hold the sand. You all think that 12-15" of sand will be enough? My kids like to dig and I dont want them to disturb the fabric.
Also, our beach area will receive virtually no runoff so I'm not going to place a berm around the beach above water because I dont think material washing onto the exposed beach will be an issue.
Thanks again for the link and help!
