FLOOD INSURANCE STUDY TOWN OF ERIE, COLORADO 1.0 INTRODUCTION 1.1 Purpose of Study This Flood Insurance Study (FIS) revises and updates a previous FIS/Flood Insurance Rate Map (FIRM) for the Town of Erie, Colorado. This information will be used by the Town of Erie to update existing floodplain regulations as part of the Regular Phase of the National Flood Insurance Program (NFIP). The information will also be used by local and regional planners to further promote sound land use and floodplain development. In some States or communities, floodplain management criteria or regulations may exist that are more restrictive or comprehensive than the minimum Federal requirements. In such cases, the more restrictive criteria take precedence and the State (or other jurisdictional agency) will be able to explain them. 1.2 Authority and Acknowledgments The hydrologic and hydraulic analyses for the area north of Perry Street, dated April 1978, were performed by Gingery Associates, Inc. (GAl), for the Federal Insurance Administration, under Contract No. H-4017. Subsequent refinements of this hydrologic and hydraulic data were developed by Water Resources Consultants, Inc. (WRC), in August 1980, and Michael Baker, Jr., Inc., in March 1981. These revisions have been incorporated into this study. The hydrologic and hydraulic analyses for the reach of Coal Creek, south of the Union Pacific Railroad (UPRR), were performed by the U . S. Department of the Interior, Bureau of Reclamation, for the Federal Emergency Management Agency (FEMA), under Contract No. EMW-87-E-2551. This study was completed in August 1988. The sources of authority for this FIS are the National Flood Insurance Act of 1968 and the Flood Disaster Protection Act of 1973. 1.3 Coordination Initial meetings to identify streams requiring detailed study within the Town of Erie were held on March 31 and April 16, 1976. These meetings were attended by representatives of the Colorado Water Conservation Board (CWCB) , FEMA, the Weld County Planning Department, and GAl. Another meeting was held on January 28, 1977, and was attended by representatives of FEMA, the Mayor and Town Clerk of Erie, and GAl. The purpose of this meeting was to gather flooding information and to outline study procedures for the reach of Coal Creek, north of the UPRR, near Perry Street. The U.S. Soil Conservation Service (SCS) (now the Natural Resources Conservation Service) was also contacted for information concerning flood hazards.
