Theo, I am doubting I will causs any issues with flooding because I will create a spillway into the creek, but I think that if the pond fills up that much its due to a flood and the creek will have spilled its banks anyhow. The area is in a floodzone (obviously, due to proximity to creek).
I am looking at taking the pond dirt and raising up some land for the house to be on and then I'll fill out a LOMA with FEMA that will hopefully take it out of the flood plain.
