Upper San Antonio River: Incorporating LID Practices at the Mission Drive-In Redevelopment
Background
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.
Project Description
For this project, the City of San Antonio will design and install several LID features to reduce pollution in stormwater runoff in its redevelopment of the Mission Drive-In site on Roosevelt Avenue. These features will include bioretention facilities and rain water harvesting at the library, and permeable pavement parking spaces and a bioswale along the site's main ring road. Project staff will monitor the performance of the LID features and then analyze their cost-to-benefit ratio. Finally, project staff will examine the potential for incorporating these features as standard components in the city's development review standards.
