SAN MARCOS, Texas — Homeowners in the Blanco Vista subdivision of San Marcos say they were caught off guard by a recent federal floodplain reclassification that has forced them to purchase flood insurance—despite extensive flood prevention infrastructure and a historically low risk of flooding.
In early 2025, residents like Victoria Meza, who purchased her home in 2021, were notified by their mortgage companies that they now had 45 days to obtain flood insurance. If not, lenders warned they would secure coverage on the homeowners’ behalf—often at a higher cost.
“My neighbor said to me, ‘Is this a joke?’” Meza recalled. “There’s a huge greenbelt behind us, the ground was raised, drainage was added—we were never told this was going to happen.”
Meza, who lives near the Blanco River, emphasized that flood prevention measures were key selling points when she bought her home. “You don’t buy a home knowing it’s going to be designated in a floodplain,” she said. “It costs you extra insurance money, makes it harder to sell, and devalues your home. I wouldn’t have done it if I had known.”
Flood Zone Redefinition Sparks Concern
The change stems from a FEMA update to the Flood Insurance Rate Maps (FIRMs) that became effective on January 17, 2025. These maps are used by mortgage lenders to determine whether properties fall within designated floodplains—areas that require mandatory flood insurance for homes with federally backed loans.
According to a statement from the city of San Marcos, the Blanco Vista neighborhood was still under design and construction when FEMA finalized its 2015 Flood Insurance Study. As a result, recent flood mitigation features—such as berms and engineered drainage systems—were not accounted for in FEMA’s latest map revision.
The city clarified that although FEMA now considers some Blanco Vista properties to be in a flood zone, local authorities do not classify homes like Meza’s as high risk. Nonetheless, the new FEMA designation triggers compulsory insurance requirements for many homeowners.
Homeowners Left Holding the Bill
Meza is one of several residents now pursuing a formal map amendment through FEMA to have their properties removed from the flood zone designation. The process, which she says will cost her $1,800 out of pocket, involves submitting documentation to prove her home is not at significant flood risk.
“This is not a wealthy neighborhood with money just to throw around,” Meza said. “It feels like a bait and switch.”
FEMA confirmed that it received a map revision request for the subdivision in April and expects to complete its initial review within 90 days.
Under Texas law, sellers are required to disclose flood risk to buyers. However, since Meza purchased her home prior to the 2025 flood map changes, no such designation existed at the time of her sale. She and others argue that had the updated maps been available earlier, their decisions may have been different.
Broader Flood Risk Still Growing
While many residents feel wrongly targeted, insurance experts caution that flood risks are growing across Texas—and flood insurance, even when not mandated, should be seriously considered.
Mark Friedlander, a spokesperson for the Insurance Information Institute, said only 14% of Texas homes and 6% nationwide are protected by flood insurance.
“You don’t want to be forced into it, with the floodplain designation,” Friedlander said. “But still, everybody should really consider it.”
He pointed to increasing incidents of flooding throughout the state in recent years. “We’ve seen severe flood events not only in the Austin area, but across the Lone Star State. You’re really not fully financially protected from the wrath of Mother Nature without flood insurance.”
Despite advancements in flood mitigation technology, FEMA flood maps are updated infrequently and often lag behind actual land developments and safety improvements. This can result in neighborhoods like Blanco Vista being classified based on outdated data—leading to mandatory insurance requirements that many see as unjustified.
Calls for Reform and Greater Transparency
The Blanco Vista situation underscores a larger issue regarding how FEMA updates flood maps and how those updates affect property owners financially.
As homeowners wait for FEMA’s review of their map amendment request, many are calling for clearer communication between developers, cities, and federal agencies. They also want legislative solutions that allow for more immediate and accurate reassessments when flood remediation efforts have been completed.
Meanwhile, as premiums rise, the episode has highlighted a growing need for consumers to carefully review all aspects of a home purchase—including the potential for unexpected insurance costs tied to shifting flood zone boundaries.
