Preliminary Summary of Map Actions (SOMA)

What is a Summary of Map Actions (SOMA) table?

In the time since the current effective FIRMs were published in February of 1999, there have been over 1,000 modifications made to the floodplain information in the form of Letters of Map Amendment (LOMA) or Letters of Map Revision (LOMR).  Some of these LOMAs and LOMRs are incorporated into the Preliminary DFIRMs and others are not. Summary of Map Actions (SOMA) tables are used to identify which map changes are incorporated into the preliminary DFIRMs and which are not.  The links below are to the Preliminary SOMA tables for each floodplain jurisdiction in Pima County.
