the BFE.

not allow runoff from outside the floodplain to aggravate properties in the
floodplain.

Floodway?
• Require evacuation plans for residents at high risk to flooding, especially
those in manufactured homes and RV Parks.
o Increased Cost Of Compliance (ICC) benefit for Repetitive Loss or
Substantial Damage Structures: to take advantage of the insurance benefit for
a repetitive loss or substantially damaged structure, there are two mandatory
be requirements (1) the property owner must have a current flood insurance
policy, and (2) the community must be enforcing repetitive loss or cumulative
- substantial damage standards. To do so, these standards must be included in
the community flood damage prevention ordinance. In most cases, the
structure will also be required to have a history of repetitive losses. If this
provision is included in the ordinance, the community must enforce it on all
structures in the community, whether or not they have flood insurance.
