Allen Parkway - Flooding

Flooding

Due to its proximity to the flood-prone Buffalo Bayou, the underpasses are subject to flooding during heavy rains and flood gauges can be seen. In June 2001, though, heavy rains from Tropical Storm Allison caused Buffalo Bayou to overtop its banks and flood the entire parkway, in some places, to a depth of eight feet. Even the KHOU-TV television studios, at a slightly higher elevation than Allen Parkway, were flooded. Most of Allen Parkway is more than 30 feet (9 m) above the normal level of Buffalo Bayou. However, the level of the bayou during the storm was more than 30 feet (9.1 m) above normal.
