<br />Guidelines and Specifications for Flood Hazard Mapping Partners [April 2003] <br /> <br />Developing the draft Scope of Project includes the following activities: <br /> <br />. Conducting background research and community outreach; <br /> <br />. Determining what effective data can be used in the analyses and/or transferred to the new <br />Flood Map Project (i.e., it may be that all data for a flooding source can simply be <br />transferred to the new Flood Map Project, or it may be that only the existing hydrologic <br />data can be used and new hydraulic analyses need to be performed, or it may be that no <br />existing data can be used); <br /> <br />. Identifying other data needed to complete the Flood Map Project and sources of those <br />data (e.g., base map, topography, cross sections, transects); <br /> <br />. Establishing priority levels for flooding sources to be analyzed and mapped; <br /> <br />. Making FIRM format decisions; <br /> <br />. Developing schedules and time and cost estimates for project tasks; and <br /> <br />. Assigning project tasks to Mapping Partners; and <br /> <br />/ <br /> <br />. Developing contract agreements. <br /> <br />The Draft Scope of Project form in Appendix I, Subsection 1.1.8 of these Guidelines shall be <br />used to document the draft Scope of Project. The draft Scope of Project is a "living" document <br />that is to be updated, when necessary. <br /> <br />Determininq Which Flood Data to Use <br /> <br />In determining the flood data to use, the Project Management Team shall consider the nature of <br />the map update need and the cost versus benefit of using a particular method of obtaining and/or <br />producing the flood data. The methods of obtaining or producing the flood data are as follows: <br /> <br />. Use of information from effective FIRM; <br /> <br />. Detailed study; <br /> <br />. Approximate study; and <br /> <br />. Redelineation of floodplain boundaries based on updated topographic information. <br /> <br />The Flood Map Project may use a combination of these methods. A detailed study is typically <br />the preferred method, but also the most costly. A "digital conversion," which involves digitizing <br />the information shown on the effective FIRM, is likely to be the least costly because no new data <br />are developed. <br /> <br />The selection of the most appropriate method for obtaining or producing the flood data for a <br />specific flooding source is primarily a function of the following: <br /> <br />1-34 <br /> <br />Section 1.3 <br />
