Upper San Antonio River: Incorporating LID Practices at the Mission Drive-In Redevelopment
Since 2000, portions of the Upper San Antonio River (Segment 1911) have had elevated concentrations of bacteria, indicating increased risk to swimmers and others engaged in contact recreation in the river. In 2006, the TCEQ accepted a watershed protection plan for the portion of this segment upstream of Loop 410 South in San Antonio. One component of this plan is to implement urban stormwater management measures that provide greater control of bacteria in runoff than conventional practices.
For this project, the City of San Antonio designed and installed several LID features to reduce pollution in stormwater runoff in its redevelopment of the Mission Drive-In site on Roosevelt Avenue. These features are an infiltration basin, pervious (turf) plaza surface, pervious pavement overlay on driveway and parking spaces, two bioswales, a rain garden, and a rainwater harvesting system connected to the site irrigation system. Project staff are monitoring the performance of the LID features and also analyzing their cost-to-benefit ratio. Finally, project staff are examining and reporting on the potential for incorporating these features as standard components in the city's development review standards.
