<br />analyzed. All of the above enter into the design of
<br />bridges, culverts, and the highways themselves, The
<br />methodologies, including computer models, used to
<br />calculate flows are all described in the Department's
<br />Design Standards. These include Natural Resources
<br />Conservation Services (NRCS) methodology, USGS
<br />Methodology for small basins, and others, COOT uses
<br />flood histories as available, When floods occur,
<br />photographs are taken and report forms are filled out.

<br />The Hydraulic Unit in Denver signs off on all projects
<br />throughout Colorado, They review any existing work by
<br />other agencies, such as the Colorado Water
<br />Conservation Board floodplain studies, and perform any
<br />additional work necessary to design structures in the
<br />floodplain, which minimize damages, The analysis is a
<br />two-step process, First, a location analysis is done,
<br />This includes public involvement and is intended as a
<br />general analysis to assure basic compliance with state
<br />and federal requirements, The second step is a
<br />hydraulic analysis, where specific design criteria are
<br />followed, These specific studies may be sent to the
<br />Colorado Water Conservation Board to assure
<br />communication on common concerns,

<br />3.2.1.5.1 Water Quality Control Division
<br />The role of the Colorado Department of Public Heatth
<br />and Environment, Division of Water Quality Control, in
<br />floodplain management relating to wastewater facilities
<br />includes three areas of involvement. First are site
<br />applications; an applicant requests approval to build a
<br />specific wastewater treatment facility in a specific
<br />location, Second are construction grant applications; an
<br />applicant requests federal financial assistance in
<br />building a wastewater treatment facility, either
<br />concurrent with or after a site application, Third is
<br />discharge permit applications; anyone who wishes to
<br />discharge pollutants (including treated waste) into a
<br />body of water in Colorado must hold a discharge permit.
<br />All three of these processes have the potential to
<br />include flood hazard mitigation opportunities,

<br />Drinking Water Program. The Drinking Water Section
<br />of the Water Quality Control Division reviews
<br />applications for domestic water supply facilities. All
<br />portions of the water supply system as far as the plant
<br />outlet, with the exception of intake structures, must be
<br />located outside the 100-year floodplain, Typically,
<br />parties building water supply facilities locate the intakes
<br />in the floodplain, for obvious reasons, and then divert
<br />the water to a high place for treatment and storage, By
<br />
<br />locating the facilities above the floodplain, increased
<br />pressure is applied to the distribution system, and
<br />locating the facilities above the floodplain reduces
<br />pumping costs. Therefore, floodplains are evaluated at
<br />the time plans and specifications are reviewed prior to
<br />construction of water treatment plants.

<br />The Office of Archaeology and Historic Preservation
<br />(OAHP) helps individuals, communities, and organiza-
<br />tions identify, protect, and preserve the state's cultural
<br />resources and to foster widespread appreciation of and
<br />respect for Colorado's cultural heritage. The State His-
<br />toric Preservation Officer (SHPO) is responsible for ad-
<br />ministering the program as defined in the National His-
<br />toric Preservation Ad. of 1966, The SHPO also adminis-
<br />ters state historic preservation laws,

<br />3.2,1.7 Colorado Natural Hazards Mitigation
<br />Council (CNHMC)
<br />For the past two decades, Colorado has experienced
<br />rapid population and business growth, Pressures have
<br />increased to build structures in floodplains, on steep
<br />slopes, in wildfire areas, and other locations previously
<br />considered unsafe or too costly to develop, Recognizing
<br />these issues, the governor signed an executive order
<br />establishing the Colorado Natural Hazards Mitigation
<br />Council (CNHMC) in March 1989, The council was
<br />created as an interdisciplinary forum for exchanging
<br />information and promoting ways to reduce and manage
<br />impacts from natural hazards,
<br />
<br />The council is composed of almost 200 volunteer
<br />committee members in the State of Colorado, The
<br />council is organized into technical and hazard specific
<br />committees, The technical committees are Public Affairs
<br />and the Steering Committee, Hazard specific
<br />committees include Severe Weather, Dam Safety, Fire
<br />Management and Mitigation, Drought, Geologic
<br />Hazards, and Flood, A recently formed Policy Advisory
<br />Group will guide overall strategy, The primary duties of
<br />the council are to:
<br />
<br />. Prioritize natural hazards in the state and review
<br />existing mitigation plans,
<br />
<br />. DevelOp a mitigation management strategy involving
<br />various levels of government.
<br />
<br />. Provide information and technical assistance to local
<br />governments and individuals,
<br />
<br />Through its volunteer committees, the council has
