The Building Official shall review all building permit
applications for new construction or substantial improvements to determine
whether proposed building sites will be reasonably safe from flooding. If
a proposed building site is in a location that has a flood hazard, any proposed
new construction or substantial improvement, including prefabricated and mobile
homes, must be designed (or modified) and anchored to prevent flotation, collapse
or lateral movement of the structure; use construction materials and utility
equipment that are resistant to flood damage; and use construction methods
and practices that will minimize flood damage.
The Building Official shall review subdivision proposals and other proposed
new developments to assure that all such proposals are consistent with the
need to minimize flood damage; that all public utilities and facilities, such
as sewer, gas, electrical and water systems, are located, elevated and constructed
to minimize or eliminate flood damage; and that adequate drainage is provided
so as to reduce exposure to flood hazard.
The Building Official shall require new or replacement water supply
systems and/or sanitary sewage systems to be designed to minimize or eliminate
infiltration of floodwaters into the systems and discharges from the systems
into floodwaters and shall require on-site waste disposal systems to be located
so as to avoid impairment of them or contamination from them during flooding.
