(2) Ail public utilities and facilities, such as sewer, gas, electrical, and water systems must be located and constructed to minimize or eliminate flood damage. (3) Adequate drainage must be provided to reduce exposure to flood hazards. Sec. 7-26. Base flood elevation data. No application for a permit which pertains to a proposed new development greater than 50 lots or 5 acres, whichever is less, in the A, A0, or Al6 zones shall be reviewed or approved unless base flood elevation data is included in the proposal, or unless such data has been previously provided pursuant to section 7-52.
