1.3 Coordination Streams requiring detailed and approximate study were identified at a meeting attended by representatives of the Study Contractor (SC), FEMA, the Colorado Water Conservation Board (CWCB), the UDFCD, and officials of the City and County of Denver on June 1, 1977. During the course of work done by the SC, hydrologic and other flood information was coordinated with FEMA, the U.S. Army Corps ofo._- Engineers (USACE), the CWCB, the UDFCD, and the City and County of Denver. 2.0 AREA STUDIED 2.1 Scope of Study This FIS covers the incorporated areas of the City and County of Denver, Colorado. The area of study is shown on the Vicinity Map (Figure 1). The City of Glendale and unincorporated areas of Arapahoe County located within Denver are not included in this study. The limits of detailed and approximate studies were determined by FEMA with community and SC consultation at the meeting on June 1, 1977. The flooding sources studied by detailed methods are shown in Table 1. The areas studied by detailed methods were selected with priority given to all known flood hazard areas and areas of projected development or proposed construction through 1986. Detailed hydraulic reanalysis of the South Platte River, conducted by Wright Water Engineers, Inc., under contract to the UDFCD, were submitted to FEMA in August 1986 and September 1987. Due to current construction of channel improvements, flooding determined for Westerly Creek has been presented in this study as approximate. Coon Creek, First Creek, and First Creek Tributary were originally studied in detail by the SC. The SC's analyses were based on basin development conditions existing along Coon Creek in 1978; and along First Creek and First Creek Tributary in 1977. Due to increased development within these stream basins, Coon Creek, First Creek, and First Creek Tributary analyses have been revised to reflect projected fully developed basin conditions. Flooding determined for these streams has been presented in this study as approximate until such time as development in these basins increases to the projected conditions. 2
