<br />Mapping Plan for Colorado <br /> <br />6.0 Prioritization of Community Mapping Needs Statewide <br /> <br />While the collection of information about mapping needs for individual communities, as described above, <br />is valuable, it does not provide a way to properly allocate the funds to meet those needs over a multi-year <br />program. There is simply not enough money to meet all of Colorado's floodplain mapping in one year. <br />The total needs of the state have to be prioritized, with the highest priority needs being addressed in the <br />first year, and lower ranked needs being addressed in future years. The methodology developed by <br />CWCB staff and the MMIP consultants was described in general terms earlier in this report. The <br />description below provides technical details of the prioritization methodology, starting first with the seven <br />individual parameters and then describing the procedures for assigning weights to the individual <br />parameters. <br /> <br />6.1 Population in 2000 <br /> <br />Using the web site of the Colorado Department of Local Affairs (DOLA), the population of each county in <br />Colorado according to the 2000 US Census was entered into the database. Because of the diversity of <br />counties in Colorado, from small mining and agricultural counties to the City and County of Denver in <br />the heart of the state's biggest metropolitan area, there was a very large range. The smallest counties had <br />total populations less than 1000. Denver has a population of over 500,000. Table 1 in Appendix B-2 <br />shows populations for the 64 counties. <br /> <br />To simplify the scoring procedure, the population figures for the counties were divided into ranges and <br />assigned values from 1 for the smallest counties to 5 for the largest counties. Table 6.1 below shows <br />those "standardized values" and the population ranges they represent. <br /> <br />Table 6.1 - Population Ranking <br /> <br />Population Standardized Value Number of Counties <br />Less than 5000 1 15 <br />5000 to 9,999 2 13 <br />10,000 to 39,999 3 21 <br />40.000 to 99 999 4 4 <br />Greater than 100,000 5 11 <br /> <br />This parameter was deemed to be important assuming that flood risks effect more people and, therefore, <br />more structures, in communities with greater populations. This parameter was viewed by the CWCB and <br />the MMIP consultants as the single most important parameter in determining the need for floodplain <br />mapping. Figure 2 illustrates the population in each county in Colorado. <br /> <br />12/26/2002 <br /> <br />Page 15 of 38 <br />
