§ 18-77. Critical facilities.

Construction of new and substantially improved critical facilities shall be located outside the limits of the special flood hazard area (one percent annual chance floodplain). Construction of new critical facilities shall be permissible within the SFHA only if no feasible alternative site is available and access to the facilities remains available during a 0.2 percent chance flood.

(1)

Critical facilities constructed within the SFHA shall have the lowest floor elevated three feet above the base flood elevation at the site (or to the 0.2 percent chance flood elevation whichever is greater).

(2)

Floodproofing and sealing measures must be implemented to ensure that any and all on-site toxic substances will not be displaced by or released into floodwaters.

(3)

Multiple access routes, elevated to or above the 0.2 percent flood elevation, shall be provided to all critical facilities to the maximum extent possible.

(4)

Critical facilities must be protected to or above the 0.2 percent chance flood and must remain operable during such an event.

a.

The community's flood response plan must list facilities considered critical in a flood.

b.

Other facilities in low risk flood zones that may also be needed to support flood response efforts must be included on the critical facility list.

(5)

The use of any structure shall not be changed to a critical facility, where such a change in use will render the new critical facility out of conformance with this section.
