Besides floodplain regulations and flood insurance, there are many actions that can
reduce the risk of flood damage in a community. Generally these actions fall into two
classes; structural actions and non-structural actions. Structural actions involve the
construction of facilities to separate floodwaters from property that is at risk. They
include construction of improved channels, enlargement of crossing structures (bridges
~and~culverts k ~levees~ and~ f.1oodwalls;~creseFVoirs ..and ~~ponds~ to~detain~~f.1oodwaters,~and
diversion channels and pipes to direct waters elsewhere. Non-structural actions usually
involve removing people and/or structures from the risk area without physically altering
the floodplain. Actions include regulation of new development, the adoption and

Flood

Flood insurance is available to owners and occupants of flood prone property through the
federal government's National Flood Insurance Program (NFIP). The federally backed
flood insurance is available to anyone in any community, such as Black Hawk, which
participates in the NFIP. Communities become participants by adopting floodplain
regulations, adopting an NFIP map (if one exists) and agreeing to cooperate with the
federal government in the local implementation of the NFIP. Property owners and
occupants can then contact an insurance agent familiar with the NFIP (perhaps their own
agent) and purchase insurance through that agent, much like they would purchase
homeowner's insurance. Brochures and other information regarding the National Flood
Insurance Program can be obtained by calling the Regional Office of the Federal
Emergency Management Agency (FEMA) in Denver at [phone].

Flood Insurance

Floodplain regulations require new development and significant improvement of existing
development cannot occur in the 100-year floodplain without a Floodplain Development
Permit. This permit is issued by the local government. To obtain a Floodplain
Development Permit, the project must comply with floodplain related engineering
standards. For floodplains which are defined using approximate methods, the
engineering standards required for a Floodplain Development Permit are fairly broad.
For example, structures must be built with materials and techniques that "minimize flood
damages" to the structures. For floodplains defined using detailed studies, more specific
regulations apply and a Floodplain Development Permit may require comprehensive
engineering analysis.

Floodplains are regulated by communities in Colorado on the local level. Communities
adopt an ordinance or regulation which broadly outlines performance standards required
for any development in identified flood hazard areas. In Colorado and nationally, special
standards are applied for development and/or construction for lands within the 100-year
floodplain.
