THEA Completes Stormwater Drainage Improvement

THEA completed a series of stormwater drainage improvements along the Selmon Expressway focused on enhancing drainage infrastructure to maintain a high level of system performance, protect roadway assets, and support long-term maintenance objectives. 

Completed work included the East Selmon Drainage Ditch Improvements from 22nd Street to Falkenburg Road, which restored ditch capacity, stabilized drainage corridors, and rehabilitated associated features to improve stormwater conveyance and overall reliability. THEA also completed the Meridian Pond Restoration, which improved stormwater retention performance through the removal of excess vegetation and regrading of the pond profile. This restoration strengthens the pond’s ability to manage runoff during heavy rain events, protecting a key drainage asset that serves the expressway. 

THEA additionally initiated a comprehensive pipe video inspection program to systematically assess the condition of underground drainage infrastructure. These inspections, combined with a robust asset management approach, enhance THEA’s ability to identify deficiencies early, prioritize maintenance, and make informed, data-driven decisions. Together, these efforts reflect a proactive approach to infrastructure stewardship that promotes long-term reliability for the communities adjacent to the Selmon Expressway.
