<br />POPULATION AND STRUCTURES AT RISK <br /> <br />INVENTORY METHODOLOGY <br /> <br />The inventory of structures was conducted with supervisory <br />assistance from Dan Bunting of the Pikes Peak Regional Building <br />Department and Mark Matulik of the Colorado Water Conservation <br />Board. Mr. Matulik and three students at UCCS were involved in <br />gathering the data. <br /> <br />Primary resources were the latest flood plain maps published <br />by the Federal Emergency Management Agency. The maps indicated <br />areas subject to potential 100 year and 500 year floods (floods <br />with 1% and 0.2% annual frequencies). Data were collected by <br />street addresses and classified under appropriate jurisdiction <br />and tributary. Estimated error in the data collection phase is <br />under three percent. <br /> <br />Data from the 1980 census of population were used in <br />estimating the population in these areas. The figure used was <br />population per household. Each residential unit was counted as <br />one household. As an example, five single family homes (or <br />multi-family units) in census tract 34, which has 2.39 <br />persons/household, equal 11.95 people. No adjustments for <br />vacancies were made. <br /> <br />Each jurisdiction was broken down by subtotals of single <br />family structures, multi-family structures, residential units, <br />single family and multi-family populations. A further breakdown <br />was' completed by tributary with the above subtotals (SFH, MFH, <br />etc.). Other data on non-residential structures were also <br />collected. All the information was compiled on computers at <br />UCCS. <br /> <br />INVENTORY RESULTS <br /> <br />The results of the regional inventory are summarized in <br />Table 2 which shows the numbers of structures and people <br />occupying the 100 year flood plains in the region and in the six <br />jurisdictions with significant risk. (2) <br /> <br />The Region contains 3,368 single family structures, 88 <br />multi-family structures and a total of 3,979 residential units in <br />its flood plains. The estimated population in these units is <br />9,338. In addition, 681 non-residential structures were <br />inventoried. <br /> <br />(2) Monument is omitted because it has only a single, non- <br />residential structure in the flood plain within its boundaries. <br /> <br />33 <br />
