<br />For a developer, the process begins with the location of the proposed <br />development. Is the area floodprone? A good starti ng poi nt in this determi na- <br />tion is the community office. A community participating in the NFIP should <br />have all the maps and related flood data prepared by the FIA (see seaion 2-2). <br />It should be stressed, however, that not all flood prone areas are shown on <br />NFIP maps. FIA limits their identification of floodprone areas to certain size <br />of drainage areas and floodplain widths. If the area appears to be susceptible <br />to flooding, check other sources of information such as soil surveys. <br /> <br />lithe proposed development lies within an identified floodplain area, then <br />the next step is to determine whether the site is within the floodway or <br />f100dway fringe, if this information exists (see Seaion 3). Depending on the <br />outcome, it will be necessary to analyze the applicable local floodplain <br />management requirements in relation tothe proposed development and make <br />adjustments, accordingly (see Seaions 4, 5, and 6). Once all plans and data <br />are prepared, the package should be submitted to the municipality for review <br />and, if necessary, to the FEMA Regional Office serving your area. An outline <br />of these procedures is shown in Figure 2. <br /> <br />2-3. Flood Hazard Analysis of NFIP Areas. The local community with <br />primary land use jurisdiaion, whether it is a municipality, county, or state, <br />has the responsibility for enforcing the National Flood Insurance Program <br />regulations through locallyenaaed ordinances if that community is participat- <br />ing in the NFIP. <br /> <br />Determination of the status of a community's participation in the NFIP and <br />review of applicable NFIP maps and ordinances are essential first steps in <br />conduaing water surface profile analysis of proposed modified or new <br />development. The NFIP maps, where available, are the least restriaive maps <br />allowed to be used in determining if the development alternative will <br />encroach on the base floodplain. Three types of maps are published: (1) a <br />Flood Hazard Boundary Map; (2) a Flood Boundary and Floodway Map; and <br />(3) a Flood Insurance Rate Map. A Flood Hazard Boundary Map is generally <br />not based on a detailed hydraulic study, and, therefore, the floodplain <br />boundaries are approximate. <br /> <br />15 SITE IN FLOODPlAINl <br /> <br />NO <br /> <br />I <br />YES <br /> <br /> 1 <br />WITHIN FlOODWAY LOCATION WITHIN WITHIN FLOC <br />FRINGE FLOODPLAIN <br /> j <br />ElEVATE/FlOODPROOF WHAT fPM NO DEVElOPI <br />STRUCTURES TO OR REQUIREMENTS ALLOWED W <br />ABOVE REGULATORY APPl Yl WILL CAUSE <br />FLOOD ELEVATION INCREASE IN lC <br /> lEVELS <br /> 1 <br /> IF ALLOWED.
