Up to date effective FEMA floodplain and LOMR information can be viewed through FEMA’s NFHL Viewer separately.

TWDB is offering a high-level statewide opinion on ranks, but will encourage users to investigate those difficult choices at the regional or local level and adjust as needed, which may include piecemeal approaches where only portions of data sets are ranked above others. </SPAN></P><P><SPAN>The TWDB is not anticipating developing any hierarchy to support, for example, regulatory activities and does not, at this time, recommend use of this broadly ranked quilt dataset for regulatory activities. </SPAN></P></DIV></DIV></DIV> |
