Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This database is an interim version of the Digital Flood Insurance Rate Map (DFIRM) Database. It does not fully meet all DFIRM specifications as found in "Guidelines and Specifications for Flood Hazard Mapping Partners, Appendix L: Guidance for Preparing Draft Digital Data and DFIRM Database". A fully compliant product is expected in 2005. Only data from the following counties are included in this dataset: Adams, Bartholomew, Benton, Blackford, Boone, Brown, Carrroll, Cass, Clark, Clay, Clinton, Crawford, Daviess, Dearborn, Decatur, Delaware, Dubois, Elkhart, Fayette, Floyd, Fountain, Franklin, Fulton, Gibson, Grant, Greene, Hancock, Harrison, Hendricks, Henry, Howard, Huntington, Jackson, Jasper, Jay, Jefferson, Jennings, Knox, Kosciusko, LaGrange, LaPorte, Lawrence, Madison, Marshall, Martin, Miami, Monroe, Montgomery, Morgan, Newton, Noble, Ohio, Orange, Owen, Parke, Perry, Pike, Porter, Posey, Pulaski, Putnam, Randolph, Ripley, Rush, Scott, Shelby, Spencer, Starke, Steuben, St. Joseph, Sullivan, Switzerland, Tippecanoe, Tipton, Unkon, Vermillion, Vigo, Wabash, Warren, Warrick, Washington, Wayne, Wells, White, Whitley. The DFIRM depicts flood risk information and supporting data used to develop the risk data. For flood insurance rating purposes, flood insurance zone designations are assigned to a community based on the results of the engineering analyses. </SPAN></P><P><SPAN>The data are best symbolized using the “Unique values, many fields” option, and selecting the FLD_ZONE field and the ZONE_SUBTY field. To categorize using FLD_ZONE/ZONE_SUBTY:</SPAN></P><UL><LI><P><SPAN>Floodways = AE/FLOODWAY; </SPAN></P></LI><LI><P><SPAN>1% Annual Chance Flood = A/ <Null>; AE/<Null>; AH/ <Null>;, and AO/ <Null>. </SPAN></P></LI><LI><P><SPAN>0.2% Annual Chance Flood Hazard = X/0.2 PCT ANNUAL CHANCE FLOOD HAZARD</SPAN></P></LI><LI><P><SPAN>0.2% Annual Chance, Protected by Levee = X/AREA WITH REDUCED FLOOD RISK DUE TO LEVEE.</SPAN></P></LI></UL><P><SPAN>The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the UTM projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000.</SPAN></P></DIV></DIV></DIV>
