Flood Damage Restoration Allen TX — Rowlett Creek Watershed
24/7 IICRC-certified flood damage restoration Allen TX homes and businesses along the Rowlett Creek watershed and areas prone to storm drain overflow.
Why Allen Floods — Rowlett Creek Watershed & Storm Drain Overflow
Allen sits within the Rowlett Creek watershed, a drainage system that also runs through Plano, Wylie, and Rowlett before eventually reaching Lake Ray Hubbard. During heavy North Texas storms, Rowlett Creek and its tributaries rise quickly, and Allen’s stormwater infrastructure — like much of Collin County — can be overwhelmed faster than it can drain.
North Texas’s clay-heavy soil compounds the problem: rainfall that would soak into sandier soil elsewhere instead runs off the surface almost immediately, overloading storm drains in low-lying Allen neighborhoods and creating flash-flood conditions along creek-adjacent streets even during storms that wouldn’t be considered extreme river-flooding events.

Allen Flood Risk Areas
These are the two flood patterns our restoration team responds to most in Allen:
Rowlett Creek Watershed Creek Flooding
Neighborhoods along Rowlett Creek and its tributaries face flash-flood risk when heavy rainfall causes rapid water rise through the watershed that also runs through Plano and Wylie.
Storm Drain Overflow — Low-Lying Streets Flash Flooding
Older and lower-lying sections of Allen can see storm drain systems overwhelmed during intense rainfall, leading to street and yard flooding even outside a mapped FEMA flood zone.
