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
The Federal Emergency Management Agency (FEMA) is updating Stanislaus County, CA flood maps in 2020. New maps identify the current flood hazards and provide data to guide building officials, contractors, and homeowners make effective mitigation decisions, thereby contributing to safer and more resilient communities.
Before the new Stanislaus County Flood Insurance Rate Maps (FIRMs) become effective, there is a 90-day appeal period from July 30 to October 28, 2020. During that time, residents with technical and scientific information, such as detailed hydraulic or hydrologic data, can appeal the flood risk information on the preliminary maps.
Flood hazards are dynamic and change frequently for many reasons, including weather patterns, erosion, and community development. FEMA, Stanislaus County, and the cities of Ceres, Modesto, Newman, and Patterson worked together to collect new or updated flood hazard data to modernize the flood maps and reflect these changes, which may also affect building or insurance requirements.
The local mapping project is part of a nationwide effort led by FEMA to increase local knowledge of flood risks and support actions to address and reduce the effects of flooding on new and improved structures. FEMA encourages residents to review the preliminary flood maps to learn about local flood risks, potential future flood insurance requirements, and identify any concerns or questions about the information provided.
Risk of flooding affects almost every corner of the nation. In total, 98% of counties have experienced a flood event, which makes floods the most common and widespread of all weather-related natural disasters. You can view the preliminary FIRMs at http://www.fema.gov/preliminaryfloodhazarddata.
