My property currently has a very very low spot in it that collects crazy water if it rains and it floods all the way to the house being built behind me. The developer claims the area has always been known to flooding so they added a drain pipe under the road. The problem is it was installed was to high so for the water to even go in there it has to flood a good bit. So I’m thinking on making it a pond and having the drain overflow to it o the pipe how would do it so that all the runoff went into the pond but isn’t to low for the overflow to go into the pipe since it’s very high
