When we built this house on the edge of the hill I made sure a 4" drain pipe ran from the gravel base under the concrete basement floor, under the foundation footing, and out to the edge of the hill. A giant gravity drain. No flood issues here.
The proof was in the early 00's when we had that giant rainstorm that sat over Sussex County and dropped something like 18" of rain in less than 36 hours. That pipe was gushing water but the basement was dry.
Now loss of electric might be different story. We are plagued with it up here since we're at the end of about an 18 mile primary feed. The generator stands ready.
You do, but they'll get emailed their reference forms. My references on my last pistol permits submitted their forms within 15 minutes of me applying for the permits so it definitely gets emailed out fast.
