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.

The City of Oceanside maintains a copy of map revisions that were submitted to the city by engineers or were received from FEMA.

• City Inventory of FIRM Map Revisions
