SECTIONTWO Program Plan <br />risks, ice jam flooding, dam failure inundation hazards, potential for wildfires, boundaries <br />of actual wildfires, and exacerbated flood risks associated with wildfires. <br />• Support FEMA's initiative to publish digital flood maps in-lieu of the traditional paper <br />FIRMs and encourage the most rapid migration possible to digital maps. This includes <br />the CWCB's advocation of a true digital mapping environment and total elimination of <br />printed map panels (or print on demand only) by January 2006. <br />These objectives, along with the details of how these activities will help achieve the Map <br />Modernization goals, are described in more depth in the sections below. After these objectives <br />are discussed below, the requirements to achieve these objectives are detailed in section 2.2. <br />Section 3 will show how the program plan will be evaluated against FEMA performance <br />measures. Lastly, the program objectives and requirements will be weighed against each other <br />for varying levels of funding in Section 4. <br />2.1.1 Statewide Needs Assessment <br />The State of Colorado initially identified a prioritized list of counties to receive map updates as <br />part of the 2002 Map Modernization Implementation Plan (MMIP), which was submitted to <br />FEMA in 2002 and is included herein by reference only. It is available from the CWCB for <br />review upon request. Since the creation of the MMIP, both FEMA and the state have reviewed <br />their initial guidance for prioritizing and selecting counties for map updates and determined that <br />some changes are warranted. As a result, the CWCB has revised its initial prioritization criteria <br />and intends to update them on an annual basis so the priority list can be a"living" document. In <br />doing this, the CWCB hopes to accommodate not only changes to guidance or criteria, but also <br />changes to watershed conditions that will alter flood risk, as well as development booms that are <br />anticipated or that may occur within the next 5-years. This approach will also accommodate <br />other factors such as "completed" mapping studies, funding availability, and local floodplain <br />mapping activities. <br />Due to changes in the natural environment and the human-impacted environment, flood risk <br />within the state is dynamic and should be evaluated on a yearly basis. As state agencies are <br />involved with or aware of many of these changes, there is frequently enough in-house knowledge <br />to update needs within a county or specific geographic area without additional input from local <br />officials every year. However, the CWCB will make a concerted effort to conduct community <br />outreach by contacting local governments via email, telephone, regular mail, or other methods to <br />convey and obtain relevant information flood-related information that will assist in assessing <br />flood hazard risk within the state. <br />Countywide Mapping Needs Assessment - The CWCB prioritization process involves a <br />quantitative, or primary, ranking of all 64 counties within Colorado, re~ardless of whether or not <br />thev have received a Di~ital Flood Insurance Rate Ma~ (Digital FIRM). Once this quantitative <br />ranking is completed, the counties are divided into equal groups, or tiers of general priority. The <br />highest-ranking group (top 25% of counties) is then evaluated based on a qualitative, or <br />secondary, set of criteria to determine the map updates that will be performed for any given <br />fiscal year. For the final year of the initial 5-year Map Modernization program the top 50% of <br />counties will be evaluated, because the current schedule calls for so many counties to be mapped <br />in FY 2008 (33 out of 64 total counties). The prioritization parameters and the rankings for the <br />quantitative portion of the needs assessment will be revisited on a yearly basis, and the remaining <br />Colorado Business Case Plan (Final Draft) 2-2 <br />
