<br />Guidelines and Specifications for Flood Hazard Mapping Partners [April 2003] <br /> <br />An Effective Map and Report Summary template is provided in Appendix I, Subsection 1.1.5 of <br />these Guidelines. <br /> <br />Researchinq Available Data for Flood Map Proiect <br /> <br />[February 2002] <br /> <br />The assigned Mapping Partner shall complete the following tasks: <br /> <br />. Identify available base map information; <br /> <br />. Identify available topographic data; <br /> <br />. Identify available flood hazard data; and <br /> <br />. Identify other available hydrologic and hydraulic information and data. <br /> <br />An Available Data Inventory template is provided in Appendix I, Subsection 1.1.6 of these <br />Guidelines. <br /> <br />The research phase of Project Scoping is critical to maximizing the value of the Flood Map <br />Project and minimizing project costs. Topographic data acquisition and- field surveys can <br />constitute up to 50 percent of the cost of a map update when all new data must be obtained. If <br />cxisting information is suitable for the planned update, it is critical that it is identified during this <br />phase and used for the Flood Map Project. <br /> <br />Applicable data may be available from a variety of sources. If FEMA has previously studied the <br />area, the FEMA archives may have detailed data from the previous study. Often, detailed <br />topographic data, cross-section surveys, and dimensions of hydraulic structures may be partially <br />or entirely applicable to the new Flood Map Project, thereby requiring surveys of new structures <br />or updated topographic information for limited areas where changes have occurred. Moreover, <br />an evaluation of the previous study may also provide a better understanding of the causes for the <br />update need and could possibly assist the Project Management Team in determining that some of <br />the existing work is still applicable. <br /> <br />Similarly, other Federal, State, and local agencies may also have performed studies that may be <br />relevant to the planned project or have generated data that may be usefuL If these contacts have <br />not been made, the Mapping Partner performing the research also shall contact the following <br />organizations to determine whether they have data that are suitable for the planned Flood Map <br />Project: <br /> <br />. Federal agencies such as USACE, NRCS, USGS, or Tennessee Valley Authority; <br /> <br />. State and regional agencies (water resource agencies, natural resource agencies, State <br />NFIP Coordinator, flood information repositories); and <br /> <br />. Agencies in the affected communities (e.g., engineering, planning, permitting, zoning). <br /> <br />1-32 <br /> <br />Section ],3 <br />
