(11) All subdivision proposals and other development proposals shall have public utilities and facilities such as sewer, gas, electrical, and water systems located and constructed to minimize flood damage. (12) All subdivision proposals and other development proposals shall have adequate drainage provided to reduce exposure to flood hazards.
