Peak dis- <br />charges for these events never exceeded the <br />ten year flood peak discharge, However, these <br />floods have disrupted highway and railroad <br />traffic, disturbed communications, drowned <br />livestock, destroyed agricultural land, roads, <br />bridges and buildings. Several lives have been <br />lost and numerous others injured, <br /> <br />The 1921 flood caused the most damage as it <br />reached a discharge of 19,000 cubic feet per <br />second. The event flooded many streets and <br />washed away several bridges, The floods of <br />1909,1933,1941,1947, and 1965 washed out <br />many bridges, including the railroad through <br />Royal Gorge, and inundated as much as 200 <br />acres of land between Canon City and <br />Florence. <br /> <br />Canon City Flood plain <br />Designation <br /> <br />In 1968, the Soil Conservation Service <br />mapped the 100 year flood plain. The flood <br />plain included the area from the northern <br /> <br />border of the city reaching south to the Arkan- <br />sas River; and from Yale Place on the western <br />border to Raynolds Avenue to the east. This <br />area includes two (2) drainage basins: (1) the <br />NortheaSt Canon Basin, and (2) the Orchard <br />Avenue Basin. The study also designated ar- <br />eas adjacent to the Arkansas river as well as <br />the adjacent areas of streams that flow into <br />the river from the South. <br /> <br />In 1982, a Flood Insurance Study was per- <br />formed for FEMA, including a flood map up- <br />date. However, only the Northeast Canon <br />Basin was re-mapped. The 100 year flood <br />plain was reduced in this basin. The Orchard <br />Avenue Basin was not updated and, therefore, <br />presently has no FEMA designated floodplain <br />within the City limits. The most recent flood <br />has proven current mapping to be incomplete, <br />since many areas outside the FEMA desig- <br />nated flood plain were flooded in 1991 (i.e., in <br />the Orchard Avenue Basin), <br /> <br /> <br />CITY OF CANON CITY. <br />COlORADO <br />FREMONT COUNTY <br /> <br />J1D <br /> <br />...V3.'_ <br /> <br />@ f,d""l Em",,,,, M.".,,,",,,, Ag,"" <br /> <br />~'TY_'_oe<x>&e <br /> <br />9 <br />
