The community must “review all permit applications to determine whetherproposed building sites will be reasonably safe from flooding. If a proposedbuilding site is in a flood-prone area, all new construction and substantialimprovements shall (i) be designed (or modified) and adequately anchoredto prevent flotation, collapse, or lateral movement of the structure resultingfrom hydrodynamic and hydrostatic loads, including the effects of buoyan-cy, (ii) be constructed with materials resistant to flood damage, (iii) be con-structed by methods and practices that minimize flood damages, and (iv) beconstructed with electrical heating, ventilation, plumbing, and air condi-tioning equipment and other service facilities that are designed and/or lo-cated so as to prevent water from entering or accumulating within the com-ponents during conditions of flooding.” [44CFR60.3(a)(3)]
