SECTIONONE Program Vision Compile the digital data into a statewide base map database for use as a scoping and assessment tool, and to facilitate flood hazard mapping activities in the future. Evaluate conditions and make recommendations to restudy flood hazards where development occurs, watershed conditions change, maps become outdated, or new information and/or methods become available. To implement these objectives the CWCB has developed a prioritization process that is based on both a quantitative and qualitative analysis of map update needs throughout Colorado. The CWCB has also selected two engineering consultant teams with flood map production experience to perform map updates during the first two fiscal years of the Map Modernization Program. Evaluation of those contracts will take place in late 2004 and the State's Purchasing Division may require re-advertisement and selection of engineering consultants for studies beyond those two years. The CWCB is currently performing map updates in Douglas and Boulder counties based on local Geographic Information System (GIS) data. Similarly, UDFCD has performed a study in the City and County of Broomfield utilizing local GIS data and is currently completing a study in the City and County of Denver and Douglas County utilizing local data. These studies are being produced as countywide Digital Flood Insurance Rate Maps according to FEMA's guidelines and specifications, and are all being performed in the vertical datum of NAVD 88, horizontal datum of NAD 83, and Universe Transverse Mercator (UTM) coordinates. It is the CWCB's intention and UDFCD's intention to perform all studies in this datum and projection so that future efforts to distribute and use the data will be as seamless as possible. It is acknowledged however, that local data may dictate the use of alternate horizontal or vertical datum, and those issues will be addressed as they arise. The CWCB will evaluate the map maintenance and flood hazard update needs on a yearly basis to ensure that the flood hazard data produced remains as accurate as possible given available funding and other resources. Below is the annual program schedule for achieving the aforementioned objectives. The schedule assumes an estimated starting month of July, corresponding to the start of the state fiscal year. Actual implementation of that annual schedule in any particular year will vary based on the approval of FEMA funding to the State.. This schedule will be fluid. While planning will begin each July, scoping, contracting, and actual mapping will be "initiated" on the date that FEMA Map Modernization funding is allocated to the State. A Gantt chart is included below in Figure 1.1 to visually depict how the bullets listed below correspond to the CWCB's fiscal year (July - June). • July through August - Perform Initial Coordination Meetings for the next FY. • September through November - Compute cost estimates for counties that had an Initial Coordination Meeting for the next FY and submit cost estimates to FEMA. • December - Reevaluate statewide needs based upon the results of Initial Coordination Meetings, annual needs assessment, and feedback from FEMA. • January through February - Update scoping tool(s), prioritization parameters, prioritization list, and Business Case Plan based upon findings from initial coordination meetings and needs assessment. Revise cost estimating tool(s) for studies based upon any new or revised unit cost data. Prepare to use revised tools and information for developing a map revision plan for the next year.
