Low Impact Development Review
Low Impact Development Technical Guidance Manual
The San Antonio River Authority in partnership with the Bexar Regional Watershed Management (BRWM) has developed a manual that outlines standard practice for design and implementation of Best Management Practices (BMPs) for Low Impact Development (LID). The following files are components of the manual which provide technical guidance on LID BMP design for policy makers, designers and regulators.

TAC Edward's Aquifer
The Edward's Aquifer recharge zone is a special case with specific design standards implemented by the Texas Commission on Environmental Quality (TCEQ). These rules do not preclude the implementation of LID BMPs but rather establish specific guidelines in their design. Click for more information from TCEQ's web site.
Overview of Low Impact Development
Low Impact Development (LID) is a group of techniques to mitigate the impact of urbanization on the hydrologic cycle. It addresses the increased quantity and decreased quality of runoff that result from increases in impervious surfaces such as concrete and asphalt. Best Management Practices (BMPs) are specific LID controls that are engineered to slow down the runoff, spread out the runoff, and soak it in. Click for more information from the EPA's web site.
Why talk to SARA?
SARA is providing LID review services to its community partners in order to promote appropriate management of the hydrology, water quality, and stream function of the San Antonio River Basin.
