<br />Guide For Approximate Zone A Areas <br /> <br />Floodplain Management <br /> <br /> <br />Figure 4 - Proposed 6.7-Acre Subdivision <br /> <br />Communities are encouraged to address the flood hazards at the <br />earliest stages of subdivision planning rather than at the <br />actual placement of individual structures. If a community can <br />work with the developer and others when land is being <br />subdivided, many long-term floodplain management benefits can <br />be achieved, particularly if the floodplain is avoided <br />altogether. In Figure 5, "Proposed 76-Lot Subdivision," the <br />entire approximate Zone A area is to be dedicated as open <br />space. If the planned subdivision shows the floodplain is <br />contained entirely within an open space lot, it may not be <br />necessary to conduct a detailed engineering analysis to <br />develop BFE data. <br /> <br />Also, it may not be necessary to develop detailed BFE data in <br />large-lot subdivisions or single-lot subdivisions that are <br />within the thresholds under Subparagraph 60.J(b) (J) of the <br />NFIP regulations when the actual building sites are clearly <br />outside of the Zone A area. In Figure 6, "Proposed 5.6-Acre <br />Subdivision," it is evident from the topographic features of <br />this 5.6-acre subdivision that the building sites would be <br />clearly out of the floodplain since the proposal indicates a <br />steep grade between the approximate Zone A area and the <br />building sites which are located on natural high ground. <br /> <br />III-J <br />
