University of Texas – Darrell K. Royal Memorial Stadium South End Zone Expansion – Austin, Texas
The new South End Zone (SEZ) fully encloses the Stadium for the first time in its 95-year history. The scope of work included the expansion and replacement of the existing SEZ bleachers and existing video display with a new SEZ, video display, and renovate portions of the adjacent Moncrief Neuhaus Athletic Center. The project provides a world-class game day experience with new exclusive suites, clubs, open air concourses, restroom facilities, new coaches offices, a banquet kitchen, premium lounge and student seating, private game-day parking, branding graphics, Longhorn Network areas, Sports Medicine/Nutrition areas, hydrotherapy, and other support spaces.
The development associated with the expansion and renovation added additional impervious cover from the pre-development to post-development condition. As a result of the increase in impervious cover, water quality and storm water detention was required to treat a portion of the stormwater runoff and attenuate for the peak discharges. The expansion of the SEZ did not allow for a traditional above ground detention pond and water quality control facility, like a sand filter. Our Civil Team was tasked with designing facilities with the challenges of space constraints, access for maintenance, and steep topography. We made several iterations of designs, but ultimately chose a Permeable Interlocking Concrete Pavement (PICP). The PICP system was designed with an aggregate base and an underdrain system. This BMP was designed to not only treat the required water quality volume, but also the voids within the aggregate base would provide sufficient detention to ensure that the project when completed would not increase storm water discharge from the pre-development condition.
