Houston's flooding history shapes everything Restorative Cleaning Solutions does. We've responded to most of these events. Crew chiefs who started during Allison are now senior project managers. Customers who flooded in Allison flooded again in Memorial Day 2015, Harvey 2017, Imelda 2019, and Beryl 2024. The patterns repeat; the response improves; the geography doesn't change.
Hurricane Beryl
Cat 1 landfall July 8 near Matagorda. 1.7M+ Houston-area outages. Widespread flooding from Brays, White Oak, Hunting bayous. RCS responded to 280+ residential calls in 14 days.
Tornado Outbreaks
March and April EF-1 to EF-2 tornadoes through Deer Park, Pasadena, Pearland. Roof damage and consequent water intrusion across thousands of homes.
Winter Storm Uri
Once-in-a-generation freeze, February 13-17. Statewide power failures lasted up to 96 hours. Houston-area frozen pipe damage estimated 100,000+ residences. Most extensive water damage event in Houston since Harvey.
Tropical Storm Beta
Stalled offshore September 17-25. Galveston seawall overtopping. Inner Loop bayou flooding 3-5 feet above normal pool. Coastal sub-surface seepage in Clear Lake.
Tropical Storm Imelda
Slow-moving September storm dropped 43 inches in some Liberty County areas. Inner Houston received 14-20 inches. Greens Bayou, Halls Bayou major flooding. 9 fatalities.
Hurricane Harvey
Stalled Cat 4 landfall August 25, dropped 51 inches on parts of Harris County over 4 days. 200,000+ Houston homes flooded. Reservoir releases inundated Memorial, Energy Corridor. The defining Houston flood event of the modern era.

Tropical Storm Allison
Stalled June 5-9, dropped 36 inches on Inner Loop Houston. 73,000 homes flooded. Texas Medical Center catastrophic flooding led to massive infrastructure investment (TMC underground flood barriers).
October Flood

Tropical Storm Claudette
Stalled near Alvin July 24-25, dropped 43 inches in 24 hours (US 24-hour rainfall record). Galveston County, Brazoria County, southern Harris County flooding.
What Houston's Flood History Tells Us
The 100-Year Storm Hits Every 3-5 Years
FEMA defines the "100-year flood" as a 1% annual chance event. Houston has experienced six such events in the past 25 years (1994, 2001, 2015, 2016, 2017, 2019). Statistical anomaly or climate shift, the practical implication is the same: Houston-area homeowners should plan for a major flood event every 3-5 years.
Bayou Geography Determines Flood Risk
The same neighborhoods flood, event after event, because the bayou hydrology hasn't changed. Brays Bayou floods Meyerland. White Oak floods Heights and Garden Oaks. Buffalo Bayou floods Memorial and Allen Parkway. Sims and Hunting bayous flood east-side and southeast Houston. If your home flooded in Harvey, it likely flooded in Allison and Imelda too — and will flood in the next major event unless mitigation has been implemented.
Reservoir Geography Matters Too
The Addicks and Barker reservoirs in west Houston are designed to detain flood water during major events. Controlled releases during Harvey caused some of the most surprising flooding (Memorial, Energy Corridor, parts of Sugar Land) because homes were inside the historical flood pool but outside FEMA's SFHA. After Harvey, FEMA updated FIRMs to expand SFHA boundaries in these areas.
What Houston Has Learned (and Hasn't)
Investments That Worked
- Texas Medical Center underground flood barriers (post-Allison, $750M)
- Sims Bayou conveyance improvements (post-1990s flooding)
- Houston Public Works major drain expansion in chronic-flood neighborhoods
- Flood Bond passed 2018 ($2.5B for Harris County Flood Control District projects)
Investments Still Pending
- Coastal Spine / Ike Dike (proposed but not constructed; storm surge protection for the Bolivar Peninsula to Galveston Bay)
- Lower Buffalo Bayou widening (Memorial corridor, partially complete)
- Addicks/Barker reservoir capacity expansion (under study)
- Brays Bayou final channel improvements through Meyerland (project ongoing)
What Repeat-Flood Homeowners Do
Many of our Meyerland and Kingwood customers have flooded 3-5 times. The ones who have recovered most efficiently share common practices:
- Maintain NFIP flood insurance even outside SFHA
- Keep digital photo inventory of contents updated annually
- Carry sewer backup rider on HO-3 policy
- Have RCS contact info pre-saved (we know their floor plans, drying patterns, plumbing layout from prior events)
- Elevate HVAC, water heater, appliances above expected flood level
- Install backflow preventer on sewer line
- Keep go-bag and document folder ready year-round
