Plan Formulation. <br /> <br />Plan Formulation consisted of evaluating all available <br />measures and then combining the most promising into several <br />alternative flood control plans. <br /> <br />a. Flood Control Measures Considered. - Nonstructural <br />measures considered to alleviate flood damages included zoning, <br />flood warning, emergency floodfight, and flood proofing (both by <br />ring levees and raising structures). Structural measures <br />considered included channel enlargement, diversions, upstream <br />storage, banks ide and setback levees, and floodwalls. <br /> <br />(1) Nonstructural. - Zoning, flood warning, and <br />emergency measures represent the existing conditions of living <br />with the flood threat. The City of Grand Junction already <br />participates in the Federal Flood Insurance Program. It was from <br />this base that local interests requested Federal assistance in <br />investigating other measures to alleviate the flood potential. <br />Accordingly, these measures (already in place) are considered <br />inadequate by the sponsors. <br /> <br />Flood warning and emergency actions have been implemented <br />historically. Snowmelt flood potential can be forecast fairly <br />accurately 1 to 2 months in advance of the peak runoff. However, <br />the problem is in identifying extended periods of warm weather or <br />heavy rains accelerating snowmelt and producing unusually high <br />runoff. This type of problem occurred in 1983 and 1984, which <br />led to flooding along the Colorado River despite the existence of <br /> <br />9 <br />
