Navigating flood protection From the cover
The big picture
there was a “significant expansion in the maps” driven by a 30% increase in rainfall rates. “Our stance has always been and will always be that everyone in Harris County should have flood insurance no matter where you live,” she said. As for cost, Houston-area insurance agent Jose Medrano said every property is unique, and the map alone no longer determines premiums. In 2023, FEMA implemented a new pricing system called Risk Rating 2.0 that uses factors such as home elevation, distance to flood sources and construction history to calculate quotes.
A before-and-after glimpse of the preliminary maps indicates more Cypress homes fall within a high-risk flood zone, potentially impacting flood insurance requirements for certain residents. The February draft reflects nearly two decades of change, as FEMA last released flood maps in 2007 using data from Tropical Storm Allison, per the agency’s website. Emily Woodell, HCFCD chief external affairs officer, said new insurance requirements won’t take effect until the map is finalized in two to three years. She said HCFCD doesn’t know the exact number of homes now in a floodplain, but
It’s been more than two months since the Federal Emergency Management Agency and the Harris County Flood Control District released the long-awaited draft maps highlighting updated flood risks across the region. While the data is a work in progress, local homeowners are wondering how the changes will impact their bills. FEMA requires all property owners with a federally-backed mortgage living in a 100-year floodplain—areas with a 1% annual chance of flooding—to obtain flood insurance through private insurers or the National Flood Insurance Program, known as NFIP.

Medrano said standard homeowners insurance does not cover flood-related damages. “Flood insurance, what that covers is damage to your property if water comes from the ground up,” he said. “Regular home insurance is if the water comes in from the sky down.” Residents can obtain flood insurance directly through FEMA or through its Write Your Own Program, which is a list of private companies that issue standardized policies regulated by the NFIP.

For those weighing the cost of flood insurance, affordability concerns may tip the scale away from the additional coverage. Annual flood insurance costs vary greatly for Harris County residents—anywhere from $500 to more than $1,000—according to FEMA data. However, some community members believe the extra protection is always worth the cost. Cy-Fair resident Jim Robertson said his annual costs have increased by about $850 since he first purchased insurance in 2001 after Allison. He said even though he lives outside the 500-year floodplain and his Lakewood Forest home has never flooded, he will continue to renew his policy. “I talked to people that had been in Lakewood Forest that said, ‘I had flood insurance forever and never flooded, so I dropped my insurance and got flooded,’” Robertson said. Medrano said residents living outside the
