(1) designate and regulate flood plain areas having special flood or mudslide hazards;

(2) prescribe standards for constructing, altering, installing or repairing buildings and other improvements under a permit system within a designated flood or mudslide hazard area;

(3) require review by the local flood plain manager for development within a designated flood or mudslide hazard area; provided that final decisions are approved by the local governing body;

(a) all such proposals are consistent with the need to minimize flood damage;

(b) all public utilities and facilities such as sewer, gas, electrical and water systems are designed to minimize or eliminate flood damage; and

(c) adequate drainage is provided so as to reduce exposure to flood hazards;

(5) require new or replacement water supply systems or sanitary sewage systems within a designated flood or mudslide hazard area to be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters and require on-site waste disposal systems to be located so as to avoid impairment of them or contamination from them during flooding; and
