Those counties, in chronological order of the work efforts, are Jefferson, Broomfield, Eagle, Grand, and Routt Counties. Jefferson County DFIRM - The preparation of a countywide DFIRM for Jefferson County and the municipalities in the county began as a FEMA effort. When preliminary maps were distributed to local officials, some of them raised concerns about discrepancies between their GIS information and the base mapping used by FEMA. Through efforts by CWCB and UDFCD, the staffs of the county and most of the municipalities were brought together at a series of meetings. Ultimately the Jefferson County GIS mapping was updated to make it consistent with the GIS mapping of the municipalities. Those adjustments to the base mapping necessitated adjustments by FEMA to the DFIRMs. In addition, some hydrologylhydraulics engineering information was adjusted. The revised DFIRMs were completed in June 2003, and they have been adopted locally. As part of the MMIP report, the local governments in Jefferson County identified a number of stream segments that were not included in the DFIRM effort, so there is still more map update work to do in Jefferson County. City and County of Broomfield - Broomfield is Colorado's newest county, comprised of the former City of Broomfield and territory from four different counties. There was a paper FIRM for the city and there were paper FIRMs for the four counties, but there was no paper or digital FIRM for the new county. Through a joint effort of UDFCD and the new county government, a draft DFIRM was prepared entirely through local efforts. With minor modifications requested by FEMA headquarters, the DFIRM has been published as Preliminary and is expected to be published as effective on August 18, 2004. Eagle County - Several years ago, FEMA began a Flood Insurance Study effort in two different geographic portions of Eagle County, one along the Eagle River between the Towns of Eagle and Gypsum, and the other along the Roaring Fork River in and around the Town of Basalt. The study faced some technical problems and was not finished as quickly as expected. In 20D3 FEMA released a DFIRM version of the study, taking advantage of the Eagle County GIS base map and a new Floodplain Information Report for the Roaring Fork River with funding from Eagle County, the neighboring jurisdiction of Pitkin County, the Town of Basalt, and the CWCB. The new study was accepted by FEMA as a replacement for the study their contractor had previously prepared for the Roaring Fork River. At the same time as the DFIRM was being completed, Eagle County, several towns along the Eagle River, and the CWCB were completing a new study on approximately 50 miles of the Eagle River and the Colorado River. FEMA agreed to accept that new study and is currently incorporating it into the DFIRM. With all of these local, state, and federal efforts, there are still stream segments identified by the local governments as needing further study after this DFIRM is fmalized. Grand County - At the request of the Town of Fraser, CWCB staff prepared approximate floodplain information for several streams in the town because Fraser had no Flood Insurance Study. CWCB submitted that information to FEMA for the possible preparation of a study for the town. FEMA decided to combine that information with floodplain information that already existed for the Towns of Granby, Grand Lake, Hot Sulphur Springs, and Winter Park to create a countywide DFIRM for Grand County. Because Grand County does not participate in the National Flood Insurance Program, there was no information available for unincorporated Colorado Business Case Plan - March 2004 1-6
