<br />. <br /> <br />'. <br /> <br />. <br /> <br />mapping represents the historic flow path of Willow Creek prior to development, and prior to re- <br />channelization that was done within the County. The CWCB has prepared a map that shows the <br />revised alignment of Willow Creek east of the corporate limits of Lamar, The map was prepared <br />using the Lamar East, Colorado USGS Quadrangle map, and is presented in the Appendix. It is <br />important to note that the depicted channel alignment has a floodplain area that is not shown on the <br />FHBM, An approximate or detailed floodplain study would have to be performed in order to define <br />the new floodplain limits. The study would have to be accepted by community officials, the <br />CWCB, and FEMA before it could become an official floodplain document for the county. <br /> <br />FLOODPLAIN MANAGEMENT <br /> <br />Local Ordinance Requirements <br /> <br />Communities which manage their floodplains in Colorado do so most often through the local <br />regulatory process. This requires a community to adopt an ordinance or regulation which sets forth <br />the performance standards by which development will occur in identified flood hazard areas. <br />Nationwide and in Colorado, regulations are enforced within the area of the loo-year floodplain. <br /> <br />The basic requirement of these regulations is that new development and significant improvement of <br />existing development cannot occur in the loo-year floodplain without a floodplain development <br />permit being obtained, Obtaining such a permit requires compliance with engineering standards. In <br />communities like Prowers County that have no detailed floodplain information with water surface <br />elevations, the engineering standards are general. Structures must be built with materials and <br />techniques that "minimize flood damages". In communities that have detailed floodplain <br />information the standards require that residential buildings must be elevated above the loo-year <br />elevation and that non-residential buildings must be either elevated or floodproofed, Other <br />structures or projects (i.e. bridges, culverts or fill) must be constructed in a way that minimizes the <br />potential increase in flood elevations they may cause, <br /> <br />Flood Insurance <br /> <br />Flood insurance is made available to owners and occupants of floodprone property through the <br />federal government's National Flood Insurance Program (NFIP). The NFIP insurance is available <br />to anyone in any community that participates in the NFIP, At the time of this publication, Prowers <br />County was participating in the NFIP, and officially joined the NFIP on July I, 1986. Communities <br />become participants by adopting floodplain regulations, adopting an NFIP map (if one exists) and <br />agreeing to cooperate with the federal govemment in the local implementation of the NFIP. <br />Property owners and occupants can then contact an insurance agent familiar with the NFIP (perhaps <br />their own agent) and purchase insurance through that agent, much like they would purchase <br />homeowner's insurance. Brochures and other information regarding the National Flood Insurance <br />Program can be obtained by calling the Regional Office of the Federal Emergency Management <br />Agency (FEMA) in Denver at (303) 235-4830. <br /> <br />6 <br />
