There are nO other projects of flood control signifIcance <br />along Monument Creek. Flows were fully contained within the channel banks downstream; <br />however, extensive erosion along the stream banks did occur. Despite the lack of damage due to <br />flooding, the strcambank erosion resulted in damage to public infrastructure and loss of private <br />property into the stream. <br /> <br />The Fountain Creek Levees and Channelization project at Pueblo is the only signifIcant flood <br />control project in this watershed. The east levee experienced some loss of ripmp through a reach, <br />but provided protection during the entire I O-year to 25-year flood event. The levee is designed <br />to contain the 200-year flood event. The levee protects 46 homes, 183 businesses, 27 public <br />stmctures, 3 apartments, and 21 storage sheds, and other outbuildings. The residential structures <br />and their contents have an estimated value of$!,511,000. The commereial structures and their <br />contents have an estimated value of$121,899,000. The public structures and their contents have <br />an estimated value of$83,646,000. The apartment structures and their wntents have an <br />estimated value of $650,000. The outbuilding structures and their contents have an estimated <br />value of $95,000. This is based on an approximate delineation of the 200-year flood plain for a <br />total value of$207,791,000. Damages do not actually begin until the 50-year flood event so <br />during this I O-year to 25-year event, the levee would not have appreciably prevented flood <br />damages. However, due to the high value of properties protected up to the 200-year event, <br />repairs are justifIed to restore full protection based on annualized damage prevention benefits. <br />The evaluation was made as part of the economic justification analysis for repair of the levee <br />riprap under the Public Law-84-99 program. <br /> <br />Arkansas River <br /> <br />Pueblo Dam and Floodway: The inflow to the dam and floodway system were generally <br /> <br />Post Flood Assessment Report <br /> <br />Chapter 4 - Flood Damages Prevented and Sustained <br />31 Draft Revised 09/09/99 <br />
