Federal flood rules are easing for about 8,000 Stockton homes along the Smith Canal, where residents have long paid high flood insurance premiums. Following major flood-control upgrades, FEMA has lifted the federal requirement for many homeowners to carry flood insurance, potentially saving families who previously faced annual bills in the thousands.
According to the San Joaquin Area Flood Control Agency, FEMA's revised Flood Insurance Rate Map for the Smith Tract takes effect on Monday and is recorded under FEMA LOMR Case No. 25-09-0442P. In its notice, the agency tells property owners in the newly remapped area that they "are no longer required to purchase flood insurance," while also cautioning that "your lender may continue to require it as a condition of the loan." Homeowners are directed to download FEMA's determination document and provide it to their loan servicers if they want an updated flood-zone determination on their mortgage.
How Many Homes Are Affected
Local reporting pegs the change at approximately 8,000 homes in north and central Stockton. ABC10 reported the remap update on Thursday, while outlets including KCRA have previously described the Smith Canal Gate as protecting roughly 8,000 property owners in the same neighborhood.
What Homeowners Should Do Next
Experts and officials are warning residents not to rush to cancel their policies. The advice is to keep flood insurance active until a lender issues a new determination and a mortgage servicer actually updates loan conditions. FEMA provides LOMC guidance that explains how a Letter of Map Revision works and how property owners or communities can submit or rely on the agency's determination when they seek changes to insurance and lending requirements.
Why The Maps Changed
The remap follows completion of the Smith Canal Gate Project, a roughly $96 million floodwall-and-gate installation that city and agency officials finished in 2024 to meet FEMA accreditation standards. Local reporting and agency releases say the gate, which is part of broader levee work tied to the Lower San Joaquin River Project, was the technical change that allowed FEMA to issue the Letter of Map Revision. Background on the gate and related projects appears in coverage from Stocktonia and in statewide project summaries from the Governor's Office.
Why This Matters For Stockton Families
If lenders accept FEMA's determination and remove mandatory flood requirements, many Stockton households could see meaningful cuts to their insurance bills. In a statement to constituents, Rep. Josh Harder has estimated savings as high as several thousand dollars a year for some homeowners, although the exact impact will depend on individual policies, property values, and how each lender responds. For now, officials are preaching patience, since lenders, mortgage servicers, and insurers all need to update their records before any single mortgage is truly free of a mandatory flood insurance requirement.
