<br />The Hazards <br />Each of the following hazards was discussed in the Hazard Identification section. Here, <br />the hazards are described in terms of how they impact the planning area. <br /> <br />Floods <br />Floods present a risk to life and property, including buildings, their contents, and their <br />use. Floods can affect crops and livestock. Floods can also affect lifeline utilities (e.g., <br />water, sewerage, and power), transportation, jobs, tourism, the environment, and the local <br />and regional economies. This is somewhat similar for all of the hazards identified with <br />the planning area. <br /> <br />However, floods are also unique, for floods are the only hazard addressed in this plan that <br />are repetitive, not only in their nature, but in their location - floodplains. Floods have an <br />annual probability of occurrence, have a known magnitude, depth and velocity for each <br />event, and in most cases, have a map indicating where they will occur! Thus, in many <br />ways, floods are often the most predictable and manageable hazard. <br /> <br />Floods have occurred frequently throughout the planning area, 93 times in the past 53 <br />years. They have caused millions of dollars in losses --- often uninsured and un- <br />reimbursed. Floods will continue to occur. As with most hazards, impacts and losses can <br />be anticipated and reduced, but nothing will keep the event from occurring again. <br /> <br />Within the planning area there are three major river basins, the South Platte River Basin, <br />the Republican River basin, and the Arkansas River Basin. Accordingly, some floods <br />have occurred within a single basin, but there are also instances when broad patterns of <br />rainfall have caused concurrent floodin in all 3 basins. <br /> <br /> <br />". <br /> <br />.0' <br /> <br />)0' <br /> <br />lS' <br /> <br />Source: Colorado Flood Hazard Mitigation Plan <br /> <br />27 <br />
