This project was part of a multi-phase, ongoing project the City of San Antonio was performing to construct storm drainage facilities in and around the IH-35/Southcross area. IDS was selected for this particular phase as part of the City’s 2007 Bond Program. The project entailed the total reconstruction and widening of more than 3,600 LF of E. Southcross Boulevard from Commercial Avenue to Marney Plaza. The project also involved the total reconstruction of almost 2,300 LF of Nobel Avenue, Tupper Avenue, and Tabor Avenue. The primary purpose of the project was to introduce a storm sewer system to the area where no storm sewer system was before. A total of more than 2,100 LF of reinforced concrete pipe was designed with diameters from 24-inches to 48-inches.
The existing water and sanitary sewer systems in the roadways were also upgraded and replaced. Approximately 3,800 LF of existing SAWS eight-inch AC sanitary sewer pipe was replaced. In addition, approximately 5,600 LF of existing Bexar Met water mains were replaced with new six-inch and eight-inch mains. The various challenges faced during the design included maintaining a traffic flow on the busy arterial street; designing a new collection system that replaced the existing system; increasing pipe slopes to meet TCEQ/SAWS requirements; and maintaining service to the 121 single family homes that were directly served by the main.
