adjacent panels and depicts the flood hazard area within the entire panel border, even in areas beyond a community corporate boundary line. In addition, under the countywide format, this single Flood Insurance Study report provides all Flood Insurance Study information and data for the entire county area, except for communities which fall within more than one county, as described in Section 1.1. The mapping for the countywide conversion has been prepared using digital data. Previously published Flood Insurance Rate Map data produced manually have been converted to vector digital data by a digitization process. These vector digital data were fit to raster digital images of the U.S. Geological Survey (USGS) quadrangle maps of the county area to provide horizontal positioning. Road and highway name and centerline data have been obtained from the TIGER files of the U.S. Department of Commerce, Bureau of the Census, and from digital mapping data prepared by the City of Aurora. These data are a digital street map. The TIGER and Aurora mapping's horizontal positioning were adjusted to match the horizontal positioning of physical features such as roads as shown on the USGS quadrangle maps of the county area. The adjusted centerline data were then computer plotted with the digitized floodplain data to produce the countywide Flood Insurance Rate Map. l.3 Coordination The coordination for the original Adams County Flood Insurance Study was completed in multi-agency conferences managed by FEMA. Officials of the Adams County Planning Commission, the Colorado Highway Department, the CWCB, the UDFCD, the USGS, the U.S. Soil Conservation Service (SCS), the U.S. Bureau of Reclamation, the USACE, Omaha District, the Denver Post newspaper, and local residents were contacted throughout this study; available maps, flood data, and historical information were obtained. On November ll, 1975, a meeting with the UDFCD, the CWCB, and the FIA was held to discuss discrepancies wi th the UDFCD study on Big Dry Creek. The results of this meeting were to use the lOO-year profile and floodway developed by the UDFCD, with the exception of the area around Interstate 25 which was adjusted to more accurately depict the lOO-year flood. It was also decided at this meeting to delete the SO-year profile because of the closeness to the lOO-year profile. On October 23 and November 28, 1975, public hearings were held by the Adams County Planning Commission to review the floodplains within the county. A final community coordination meeting was held with the public and representatives from Gingery Associates, the Adams County Planning Commission, the UDFCD, and the FIA on August 26, 1976, to present and discuss the flood information prepared for the county. There were no problems raised at this meeting. 3
