Letter of Map Revisions
Villages of Patterson-Letter of Map Revision
The city of Patterson has sponsored a Letter of Map Revision (LOMR) for the Villages of Patterson planning area. This area is bounded by the Union Pacific Railroad (UPRR) tracks of the west, Eucalyptus Avenue on the north, Sycamore Avenue on the east and Walnut Avenue on the south. The requested map revision is based on updated hydrologic information compiled by the U.S. Army Corp Of Engineers and does not include any physical changes inside or outside the proposed map revision area.
Based on this hydrologic information, the Flood Insurance Study Report and Flood Insurance Rate Maps for the community of Patterson has been revised. To view the revised map panels, please see below.
A notice of the changes will be published in the Federal Register. This information has been published in the local newspaper on or about the dates listed below and through FEMA's Flood Hazard Mapping Website.
LOCAL NEWSPAPER Name: Patterson Irrigator Dates: March 29, 2018 and April 5, 2018
Within 90 days of the second publication in the local newspaper, any interested party may request that we reconsider this determination. Any request for reconsideration must be based on scientific or technical data. Therefore, this revision will be effective only after the 90-day appeal period has elapsed and we have resolved any appeals that we receive during this appeal period. Until this LOMR is effective, the revised flood hazard determination presented in this LOMR may be changed.
Flood Map Revision Project-San Joaquin River
In January 2018 FEMA's contractor, STARR II, provided draft mapping of 1% annual chance (100-year) and 0.2% annual chance (500-year) flood areas and flood elevations behind the levees along the San Joaquin River. The work maps were produced following FEMA's Natural Valley procedure and used recent models and topographic data from California Department of Water Resources. We are currently in the 60-day internal review and comment period. The city will post more information as it becomes available. A full map revision is not anticipated until 2019.
If you have any questions on any of these revisions, please call (209) 895-8061 or email us.
