Letter of Map Revisions (LOMR) Review Partner

The San Antonio River Authority (River Authority) has partnered with the Federal Emergency Management Agency (FEMA) as part of the Letter of Map Revision Delegation Program that enables the River Authority to review proposed revisions to floodplain maps within its four county jurisdiction. In its capacity as a FEMA Delegation Program partner, the River Authority is responsible for reviewing floodplain maps for revisions throughout Bexar, Wilson, Karnes and Goliad counties (including all incorporated communities). Those revisions are known as Letter of Map Revisions (LOMR) and Conditional Letter of Map Revisions (CLOMR). The River Authority officially began receiving submittals in 2012. By serving as a FEMA’s LOMR/CLOMR delegate, the River Authority is able to provide certain benefits to communities throughout its jurisdiction, including the following:

  1. Management of local engineering models, supporting data and floodplain maps;
  2. Local coordination of adjacent map revision request;
  3. Availability of local San Antonio River Authority staff to discuss submittals; and
  4. Knowledge of local area projects and issues that might impact current map and future revisions.
