<br />GRAND JUNCTION RIVERFRONT DEVELOPMENT <br />SECTION 22 <br />PLANNING ASSISTANCE TO THE STATE OF COLORADO <br /> <br />1. StudY Authoritv. <br /> <br />This study was conducted in accordance with the provisions <br />of section 22 of Public Law 93-251. section 22 of the law <br />authorizes the Chief of Engineers to cooperate with States in the <br />preparation of comprehensive plans for the development, use, and <br />conservation of the water and related land resources for drainage <br />basins located within the boundaries of the States. <br /> <br />In February of 1990, the Colorado Water Conservation Board <br />required the Sacramento District corps of Engineers (Corps), <br />under section 22 Planning Assistance to the States from the State <br />of Colorado to undertake an investigation to inventory the Grand <br />Valley levee system along the Colorado River from Palisade to <br />Loma. The request stated that due to the 1983 and 1984 floods in <br />the Grand Junction area, the "...levee system was stressed and <br />failed at a number of locations." The request expressed concern <br />that "complete failure of the levee system would be catastrophic <br />to certain areas of the community." <br /> <br />2. Location and Descriotion. <br /> <br />, <br /> <br />The City of Grand Junction, in the Grand Valley, is located <br />in western Colorado at the confluence of the Colorado and <br />Gunnison Rivers. The 1990 census estimate for the population of <br />the city of Grand Junction is 29,034. The Mesa County population <br />estimate is 93,145. The population of the Grand Valley is <br />estimated by the Grand Junction Planning Department at between <br />82,000 to 84,000. The main economic activities in the Grand <br />Valley are agriculture and tourism; however, light manufaCturing <br />and governmental activities are also important. Grand Junction <br />is at an elevation of 4,600 feet above mean sea level. The <br />climate is semi-arid with about 8 inches of annual precipitation; <br />at nearby higher elevations, annual precipitation can exceed <br />40 inches per year, mostly as snow. <br /> <br />, <br /> <br />The study area for this effort included the Colorado River <br />from where it exits DeBeque Canyon at palisade, Colorado, past <br />the City of Grand Junction, to the boat launch near the town of <br />Loma, Colorado. The study reach was inventoried from station <br />403.0 at the upstream limit to station 369.0 at the downstream <br />limit, a distance of 34 miles along the Colorado River. <br />
