The U.S. Department of Homeland Security’s Federal Emergency Management Agency (FEMA) intends to provide federal financial assistance under the Legislative Pre-Disaster Mitigation Program to San Joaquin County in San Joaquin County, California, to improve water and storm drainage system reliability and resiliency against power outages during storm and flood events. The proposed action would mitigate impacts from flood hazards by installing five emergency backup generators and upgrading one pump at existing pump stations. Pursuant to Executive Order 11988 (Floodplain Management) and FEMA’s implementing regulations at Title 44 of the Code of Federal Regulations Part 9, FEMA hereby provides interested parties with a notice of its intent to carry out an action affecting a floodplain.

The purpose of the proposed action is to reduce flood hazards. The proposed action would occur at five pump station locations and consists of installing a new gas generator and upgrading the existing pump at one location, replacing an existing generator with a new gas generator at another location, and installing new gas generators at three other locations. The generators would be installed with new gas connections, automatic transfer switches, and electrical connections with new electrical service. The proposed generators would be placed on concrete pads. Services would feed from the public right-of-way to each site with new gas meters installed prior to connection of each generator. 

The proposed pump improvements would discharge flows to Fourteen Mile Slough which is in the 100-year floodplain as depicted on the FEMA Flood Insurance Rate Map (FIRM), Map Number 06077C0455F, effective date October 16, 2009. The FIRM shows that Fourteen Mile Slough lies within Zone AE, an area that has a 1-percent probability of flooding every year and where predicted floodwater elevations have been established.

Additional information about FEMA’s proposed action, including maps showing the potential impacts on floodplains, may be obtained by writing the FEMA Region 9 Environmental Officer at FEMA, 1111 Broadway, Suite 1200, Oakland, California 94607, or fema-rix-ehp-documents@fema.dhs.gov. All requests should be received within 15 days after publication of this notice.
