<br />Mapping Plan for Colorado <br /> <br />. Level 1 unit costs for UD&FCD counties is based on recent cost estimates to update Adams <br />County maps. Based on the Adams County estimate (excluding the South Platte River FHAD <br />costs) an approximate cost of $1,300 per mile is assumed. <br /> <br />. There is an average of 5.4 miles per panel in Adams County. Estimated cost per panel is 5.4 <br />miles x $1,300 per mile or $7,000 per panel. <br /> <br />. Level 1 unit prices for non UD&FCD counties is based on assuming 2/3 of each county is rural <br />and is similar to UD&FCD estimated cost to update non-UD&FCD parts of Adams County and <br />1/3 of county is urban and is similar to UD&FCD cost to update the part of Adams County within <br />the UD&FCD. The average cost per mile is 1,000 per mile. Assuming that there is 3 miles per <br />panel the estimated cost per panel is 3 miles x $1,000 per mile or $3,000 per panel. <br /> <br />. The number of stream miles for Level 2 study for counties with insufficient information is <br />assumed to be a minimum of 15 miles for unincorporated areas. <br /> <br />. The exceptions are that no extra miles were assumed where there are no or few existing panels or <br />where the county is a non-NFIP community. <br /> <br />. Level 2 unit prices are based on $8,000/stream mile in non-UD&FCD counties. Number of <br />stream miles per panel is 3 for a unit price of$24,000 per panel. <br /> <br />. Level 2 unit prices based on $1 O,OOO/stream mile in UD&FCD counties. Number of stream miles <br />per panel is 3 for a unit price of$30,000 per panel. <br /> <br />An important additional assumption must be made clear: <br /> <br />. No costs were developed for communities that do not currently participate in the NFIP, and <br />that did not submit any map update needs to the CWCB. <br /> <br />12/26/2002 <br /> <br />Page 37 of 38 <br />
