Project Overview

The Seeling Channel Phase 3 project constructed by Sundt Construction is a continuation of a multi-phased floodplain improvement project that includes the reconstruction and widening of Seeling Channel along with residential improvements to curbs, sidewalks and driveway approaches. In an effort to further reduce the floodplain around the residents of San Antonio, Sundt reconstructed Summit Alley and installed additional drainage flumes between St. Cloud and Morning glory.

The City of San Antonio classified the Seeling Channel near Woodlawn Lake as a serious threat to the health and safety of the community. The design aimed to avert a repeat catastrophic flooding that occurred in 2002. The three phases of improvements will remove approximately 200 residential and business properties from the flood plain.

The reconstruction of an active drainage channel presented its own unique challenges to the project team. Through perseverance, the team was able to plan and implement innovative water diversion methods needed to successfully deliver the project. Improvements to the existing 2,200 linear-foot stretch of channel included over 50,000 cubic yards of excavation, placement of 10,000 cubic yards of concrete in CIP retaining walls and channel bottom, demolition and rebuild of St Cloud Bridge over the channel; 4,500 linear feet of chain link fence and over 2,000 linear feet of water, sanitary sewer, gas and storm drain utility relocations and replacements.
