FEMA has established administrative procedures for changing effective Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS) reports based on new or revised scientific or technical data. A physical change to the affected FIRM panels and portions of the FIS is referred to as a ''physical map revision.'' When FEMA revises a community's FIRM, the community is required to amend its floodplain management regulations within 6 months of being notified to incorporate the new data. Changes can also be made by a Letter of Map Change (LOMC) and there are several categories of LOMCs, depending on the complexity of the changes.
City of Oceanside maintains copy of map revisions that were submitted to the city by engineers or were received from FEMA.
