Galveston begins major drainage upgrade to curb mid-island flooding
GALVESTON, Texas (UI) — Construction is now underway on the South Shore Drainage Project, a long-planned effort to reduce flooding in Galveston’s mid-island neighborhoods. Work began this month and includes installation of new stormwater infrastructure and construction of a pump station along Offatts Bayou.
The project is a key part of the City of Galveston’s flood-risk-reduction strategy, which focuses on improving aging drainage systems and protecting residents during major rainstorms and high-tide events.
Once completed, the upgrades will lessen the duration and severity of street flooding during both sunny-day tidal flooding and severe weather, helping maintain emergency access for residents and first responders.
The South Shore Drainage Project includes system upgrades along Bayou Shore Drive, South Shore Drive, Heards Lane, and 59th Street, replacing deteriorating stormwater infrastructure and pavement. In addition to drainage improvements, the project will enhance roadway safety and reliability in these corridors.
The centerpiece of the project is a new pump station that will divert stormwater runoff into English Bayou during heavy rain or high-tide events, preventing water from backing up into neighborhood streets.
To further boost performance, sluice gates will be installed on gravity collection system outfalls. These gates will help reduce the impact of high tides, prevent recirculation of pump discharge, and lower the risk of localized flooding.
Earlier this month, the City hosted an open house to update residents and gather feedback on the project. More than 15 city staff members and engineers attended to explain the construction timeline, design details, and anticipated benefits.
