Performance Goals

on high population urban counties early, addressing the needs of lower population rural counties
later. For FY 2006 and FY 2007 the total proposed annual budget is similar to the proposed
annual budget for FY 2004 and FY 2005. That is because estimated costs for many of the rural
counties are lower than estimated costs for urban counties, so more counties can be studied for
the same total budget. That is not true for FY 2008 because the total number of counties left to
map is so great.

It is important to note that despite all the work that has gone into cost estimates for updating the
counties maps, they are still preliminary estimates. No Initial Coordination Meetings or Scoping
Meetings have been performed, so cost estimates are somewhat general. The source data for the
cost estimates is based in large part on data provided by community staff without benefit of
initial coordination and scoping support from CWeB.

The CWCB recognizes and understands that considerable time and effort is required to perform
pre-scoping and scoping activities prior to finalizing cost estimates for each county. In the event
that a community has not reported or has underestimated the flood mapping needs within its
jurisdiction, the cost to actually update the FIRM maps in these areas will be higher than the
current estimates.

The CWCB is currently unable to estimate, with any certainty, the actual cost to perform
these studies until Initial Coordination Meetings and Scoping Meetings are conducted and
more accurate panel counts and stream miles are established. The estimates provided in this
report should be used for planning purposes only. These estimates will be revised as part of the
annual update of the Business Case Plan as studies are completed and as more information is
gathered on the potential scope of work for each of these county mapping efforts.

The current funding levels severely inhibit Colorado's ability to reach FEMA's performance
goals. To illustrate this point, at the rate of current FEMA funding (~$1 ,000,000 per year) the
CWCB would need to produce 11 countywide DFIRMs per year at a ridiculously low cost of
approximately $85,000 per county in order to achieve all of the performance metrics in Table
4.1. More information on the difficulty of achieving this performance goal is outlined in
Appendix F.

A summary listing of the counties and a description of the tasks that can be performed for the
three funding levels outlined above, as well as a year-by-year cost breakdown and projected Map
Modernization schedule, is included in Section Five.
