12 Pa. Code § 111.1
The Department has determined that the public welfare is served by assisting persons in flood-prone municipalities to protect themselves against flood losses with the insurance coverage available under the National Flood Insurance Act of 1968 (42 U.S.C.A. §§ 4001-4127). Under Federal law, these persons cannot obtain subsidized flood insurance unless the municipalities in which they are located are eligible to participate in the National Flood Insurance program. To encourage municipalities to seek eligibility and to enact prudent flood plain land use controls, the Department will not approve a grant-in-aid application from a flood prone municipality unless the municipality is eligible for the National Flood Insurance program.
