Can you hear the rush of water? Here at Brickhouse Gully at Costa Rica Street, it’s a constant reminder of Houston’s dynamic relationship with water. Brickhouse Gully isn’t just a concrete channel. It’s a vital part of Houston’s flood control system, a testament to the city’s ongoing efforts to manage the powerful forces of nature. This gully, formally identified as HCFCD Unit E115-00-00, plays a crucial role in draining a significant portion of central Harris County within the White Oak Bayou watershed. It stretches from west to east, primarily within Beltway 8, north of IH-10 and west of U.S. 290.
Brickhouse Gully has a history of flooding. It currently offers a relatively low level of service, ranging from 50% (two-year) in the downstream and central reaches to a mere 1% (100-year) upstream. This means that structural flooding is a common occurrence during heavy rain events. In fact, the Harris County Flood Control District’s voluntary home buyout program includes several areas within the Brickhouse Gully watershed. The Flood Control District, recognizing the urgent need for improved flood management, initiated a study in 2018. This study aimed to investigate and identify solutions to mitigate flood risks along Brickhouse Gully. The goals were to quantify existing risks, identify ways to reduce flood depth, duration, and frequency, and pinpoint potential locations for stormwater detention.
Interestingly, the Brickhouse Gully watershed is almost entirely developed. This fact led to a joint funding agreement between the Flood Control District and the City of Houston for this crucial investigation. The study area falls within Houston’s city limits, further highlighting the collaboration between city and county authorities. The recommended solutions will encompass channel improvements, stormwater detention, diversion, and right-of-way needs. The 2018 Bond Program has allocated $35 million for the acquisition, design, and construction of improvements stemming from this engineering investigation. Brickhouse Gully stands as a symbol of Houston’s continuous adaptation to its environment. It represents the city’s commitment to protecting its citizens from the ever-present threat of flooding.
