Floodwater gushed from a manhole at the intersection of Hanna and Houston streets in Washington, Pennsylvania on Saturday, forcing crews to rope off part of Hanna Street as fast-moving runoff swamped roads across Washington and Allegheny counties. Along Houston Street, homeowners waded out to clean up around properties that had flooded yet again, with one resident calling the situation simply “despicable.”
The scene was especially harrowing for one Houston Street family, whose green van stalled in the rising water with a 6-year-old niece and another family member still inside, according to WPXI. An unidentified man pulled the child out through the vehicle's window as water crept toward the second step of the woman's porch. The same report notes the woman now has three vehicles that won't start because of flood damage, on top of one working car, and that her family had previously lost personal belongings to earlier flooding this summer.
Neighbors along Houston Street believe clogged storm drains are worsening a flooding problem that has repeatedly hit the area all season, and they're hoping for drainage-system improvements to finally break the cycle, the station's report adds. City officials, however, point to a much bigger storm system driving Saturday's chaos: Washington Mayor JoJo Burgess declared a state of emergency on Saturday after severe late-afternoon downpours swamped city streets and threatened resident safety.
A Storm That Overwhelmed Creeks and Culverts
That storm overwhelmed Catfish Creek, which overflowed its banks near Cameron Stadium in Washington, inundating nearby properties and causing stormwater drains at Jefferson and Wylie avenues to spout water under intense pressure, according to the Observer-Reporter.
Across the county line in Allegheny County, runoff spilling from the Streets Run watershed sent water pouring onto Baldwin Road's pavement, and emergency responders closed Streets Run Road between Brentwood Road and the Pittsburgh city line as police blocked flooded stretches nearby. Drivers who ventured onto Baldwin Road navigated through the floodwater slowly, while at least one homeowner in the area said the drains there need to be cleaned out badly, echoing the frustration voiced by residents on Houston Street.
Aging Infrastructure Meets a Wet Summer
Part of the trouble tracing back to Catfish Creek involves infrastructure built nearly a century ago. PennDOT District 12 has been executing a $2.25 million bridge replacement and pre-cast concrete box culvert project over Catfish Creek at Route 18, or South Main Street, in Washington, replacing a restrictive concrete box culvert originally built in 1928, according to the Pennsylvania Department of Transportation.
A separate, larger fix is planned for the Streets Run corridor in Allegheny County. PennDOT has slated a betterment project spanning 4.6 miles of Streets Run Road across Baldwin, West Mifflin, Whitehall and Pittsburgh for 2027 through 2028, featuring retaining walls and drainage upgrades, per state planning documents. That timeline reflects the scale of the challenge: the Streets Run watershed spans eight separate municipalities, including Baldwin, Whitehall, West Mifflin, Brentwood, Munhall, Homestead, West Homestead and Pittsburgh, according to Watersheds of South Pittsburgh.
Why Washington's Creeks Keep Overwhelming Storm Drains
Washington County's flood planning has included a study of Catfish Creek and Chartiers Creek. The focus on those waterways helps explain why smaller streams near homes remain part of the area's flood concerns.
Saturday's storm was also the latest in a pattern stretching back weeks. Southwestern Pennsylvania saw repeated severe flash flooding through August and early September, including an August 5 storm that submerged West Pike Street in Canonsburg and swamped Morganza Road in North Strabane, WPXI reported separately at the time. Hoodline previously covered flooding that stranded concertgoers along Route 51 just a week before Saturday's storm, part of the same regional pattern of saturated ground and overwhelmed drainage.
State regulations also shape efforts to keep creeks clear. For homeowners on Houston Street and Baldwin Road pushing for cleaner drains, the Catfish Creek Route 18 culvert project is underway, while the Streets Run Road betterment project is planned for 2027 through 2028 as longer-term fixes discussed here.
