<br />DAMAGE 1\?SEo~<;l'1EN1~ <br /> <br />Due to the present capacity and condition of the major drainageways in <br /> <br /> <br />Montrose, considerable damage would result during a severe -nood. The <br /> <br />various types of damages which could occur are: <br /> <br />Damage to structures <br />Damage to contents of structures <br /> <br />Damage to utilities <br /> <br />Damage to streets and roads <br /> <br />Damage to bridges and culverts <br />Agricultural damage <br /> <br />Disruption of normal services <br /> <br />Through construction of channel improvements, damages can be el iminated <br /> <br />or greatly reduced and are the major bE~nefit resul ting from the drainageway <br /> <br />improvements. <br /> <br />Potential flood damages for structures within the study area were es- <br /> <br />timated using the information developed in the hydraulic analysis and depth- <br /> <br />damage curves. <br />These curves tabulate damage as a percent of tota-I structure val ue <br /> <br />based on flood depth above the structure's first floor elevation. A <br /> <br />separate curve was used for each type of structure. For residential <br />structures curves developed by the Federal Insurance Administration in <br />1974 showing damage to the structure and its contents were used. For <br /> <br />industrial and commercial structures, damages were estimated with curves <br />presented in a-t~~s prepared at Colorado State University, (Reference 6). <br /> <br />Structures within the flodoplain are summarized in Table 1. <br /> <br /> <br />Direct damages are those damages which occur to the structure and <br /> <br /> <br />its contents, and are calculated based on flood depths.
