<br />Though this house re-
<br />mained intact, the force of
<br />a coastal flood knocked it
<br />off its foundation, causing
<br />extensive damage.
<br />
<br />conceivably can be included in building codes In regard
<br />to flooding. For example:
<br />. Codes may prohibit basements in certain areas or
<br />can require that basements be floodproofed to pro-
<br />tect against damage.
<br />. Structural reinforcements, waterproofing, or other
<br />protective measures may be required for structures
<br />with the first floor or basement below the base
<br />flood elevation.
<br />. Buildings may be required to be anchored to pre-
<br />vent flotation during flooding.
<br />. Building materials for use in flood-prone areas may
<br />be specified.
<br />One of the national model codes does make gen-
<br />eral references to flood-related standards. The Building
<br />Officals and Code Administrators (BOCA) model code
<br />includes sections requiring structural integrity of foun-
<br />dations, walls, floor slabs, and retaining walls that might
<br />be subjected to water pressure. This model code (see
<br />the Resource Index for specific sections of the BOCA
<br />model code) is used in many parts of the country, often
<br />being adopted by reference. Other communities may
<br />have similar or more stringent requirement'), and the
<br />designer should consult with local or state building offi-
<br />cials to ascertain what codes are in effect.
<br />
<br />State Programs
<br />Some states have regulations applying to development
<br />in floodplains, along river channels, or in coastal zones.
<br />These regulations may be parallel to local requirements
<br />or in addition to them. The appropriate state govern-
<br />ment departments responsible for floodplain manage-
<br />ment, water resources, building codes or coastal zone
<br />management should be consulted prior to design of any
<br />project in a flood hazard area (state agencies are listed
<br />in the Resource Index).
<br />Each state has designated a State Coordinating
