Upper San Antonio River Watershed Protection Plan Implementation: Green Stormwater Infrastructure Master Plan
San Antonio River Authority is developing a master plan for using green stormwater infrastructure.

Background
Since 2000, portions of the Upper San Antonio River have been listed in the Texas Integrated Report as impaired (not meeting Water Quality Standards) because levels of fecal bacteria have exceeded the contact recreation standard. In 2006, the San Antonio River Authority (SARA) completed the Upper San Antonio River Watershed Protection Plan (WPP) and in 2007 TCEQ adopted a total maximum daily load for this segment. The WPP recommends implementing low impact development (LID), a best management practice (BMP) for reducing stormwater pollution.
Project Description
San Antonio River Authority (SARA) is developing a master plan for the use of green stormwater infrastructure (GSI), informed by stakeholder input. It will recommend BMPs for improving water quality and managing stormwater quantity and prioritize them based on cost effectiveness. SARA’s watershed scale models identified sub-basins with the highest pollutant contributions which will be used to prioritize sites with the highest potential for effective GSI implementation. The completed GSI Master Plan can become a template for implementation in other watersheds.
