ArcGIS Online ContentThis coverage was begun in March of 1998 for the Permit and Information Center (PIC) staff to keep track of the parcels that had successfully filed a Letter of Map Amendment (LOMA) and been granted a Letter of Map Revision (LOMR). A LOMA is an official revision by letter to a current Flood Insurance Rate Map (FIRM). A LOMA results from an administrative procedure that involves the review of scientific or technical data submitted by the owner or lessee of property who believes the property has incorrectly been included in a designated Special Flood Hazard Area (SFHA). A LOMA amends the current FIRM map and establishes that a specific property is not located in an SFHA. A LOMR is an official revision to the current FIRM. It is used to change flood zones, floodplain and floodway delineations, flood elevations, and planimetric features.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/6390a29974644f66a50633bb0b91ca8e_0engCity of Eugene Mapping HubPublicEugene Flood Revisions (LOMCs) - HUB [Oregon--Eugene]Web servicesOregon--EugeneOregonLast Modified: 2026-01-07
