SECTIONTWO Program Plan 2.1.4.3 Site Specific Mapping Due to the uncertainties associated with a 5-year plan the CWCB has established site-specific flood hazard mapping alternatives to be implemented, as the CWCB and communities jointly deem necessary and as funding is available, in order to increase the flexibility of Colorado's flood mapping program. Most site-specific mapping will involve a Detailed Method analysis of flooding hazards, but such mapping could include any of the study tasks identified in Appendix D. The following methods have been identified to publish site-specific mapping data. From most to least preferred, the methods are: • Physical Map Revision (PMR) • Letter of Map Revision (LOMR) • Best Available Data (BADL) The CWCB is currently contracting DFIRM production that includes printing of the preliminary FIRMs and preparation of final Government Printing Office (GPO) deliverables. Colorado is prepared to perform this function for areas where existing flood maps warrant a physical map revision (i.e. the effective information is inadequate) including printing and issuing preliminaries as well as preparing negatives for the GPO. These tasks can be performed for studies that revise one or more FIRM panels, provided adequate funding is available from FEMA. In other words, once a countywide DFIRM has been completed, if there is a need for a revised hydraulic analysis and subsequent revised map panel from FEMA the CWCB is willing to produce the preliminary maps and finalize the maps for GPO as long as there is funding in our budget from FEMA to perform those tasks. Colorado does not have the desire or ability to assume any of GPO's responsibilities at this time.. 2.1.4.4 Mapping for the Digital Future The CWCB acknowledges that digital floodplain maps may be considered legal documents and that they may be distributed based on a"mapping on demand" format in the future. Therefore, the CWCB intends to position itself to contribute to the future of floodplain mapping by building into this Plan the capability to distribute the data in a digital format in future years. In doing this, the CWCB also hopes to realize efficiencies in map production costs by eliminating paper map production thereby allowing the CWCB to perform more floodplain studies with the same amount of funding. (It is anticipated that the shift to digital floodplain maps will reduce the amount of funding that is spent to comply with FEMA's current Graphical Specifications). For the short-term interim period when paper maps are still being produced, the CWCB stipulates that a custom collar be used for all Colorado studies that is not necessarily consistent with the national collar standard that may be used by FEMA or its National Service Provider. See Figure 2.1 below for a preliminary draft of the Douglas County DFIRM that we are currently producing for FEMA as an "early implementation success story" which includes the custom collar referenced above.
