Buildings (excepting those that are functionally dependent upon water
or those that facilitate open space use) which are located within le-
vees should be relocated and future development in these locations
must not be allowed.

Progress:

Emphasis will be placed on relocating substantially damaged buildings
in Mohave County because the more serious problems are located there.

Both States have been directed to include a plan for each county in the
Section 406 Hazard Mitigation Plan to:

1. Apply the NFIP requirements to the areas mapped by BuRec FPls
but not yet mapped by FEMA;

2. Use the BuRec FPls as the best information available in areas
of approximate mapping by FEMA;

3. Apply the NFIP floodway standards to the BuRec floodway in
areas where FEMA has not yet delineated a floodway;

4. Apply the NFIP floodway standards to the areas within BuRec
levees.

The implementation of these plans will assure that new construction is
prohibited within levees. The following is the status of buildings lo-
cated within levees in each community:

Mohave County, Arizona -- There are many buildings located within levees
in the County; most are in the Bermuda Plantation area. Many were con-
structed before the County's floodplain zoning ordinance, while others,
according to the County, were constructed without the required permits
and the County has been attempting to abate them. Some are substantially
damaged, some have minor damage and some are not damaged at all,.

The State Division of Emergency Services and the County held a public
meeting on September 27, 1983, to provide information to the property
owners in Bermuda Plantation and the Topock Marsh areas. Topock Marsh
is not located within levees but sustained flooding up to six feet deep
and the homes have been inundated for three months. Relocation was dis-
cussed at the meeting. The majority of the Bermuda Plantation,property
owners do not wish to relocate and are pressuring the County to allow
fill within the levees to protect their structures.

The Topock Marsh property owners, however, are interested in relocation
and are exploring the possibility of using.HUD funds and Section 1362 ~o
