Does the institution have a policy, plan, and/or strategies to reduce stormwater runoff from new development projects? :
Yes

Does the institution have a policy, plan, and/or strategies to reduce stormwater runoff from ongoing campus operations? :
Yes

A brief description of the institution's stormwater management initiatives:

The University of Texas at San Antonio provides temporary storm water treatment for construction projects. Projects employ a variety of storm water Best Management Practices (BMP’s) so that solids attributed to construction sites can be minimized before entering the storm system or open water ways.

Ongoing campus operations are closely monitored for water quality. The university regulates operations, development , and university events in order to reduce discharge of water laden with suspended solids or regulated and hazardous materials into our sewers and open water ways. This includes spill containment planning, prevention, emergency contact information, and education. Impervious cover is treated with permanent BMP’s including vegetative filter strips, water quality treatment basins and vegetated treatment swales. Management activities are in place and personnel are provided to protect the effectiveness of these controls.

Does the institution have a living or vegetated roof?:

Does the institution have porous paving?:
Yes

A brief description of the institution's porous paving:

The UTSA main campus uses porous paving as an alternative to sidewalks and low impact parking as a means to reduce impervious cover. While the porous cover is more pervious than concrete or asphalt, BMP’s are still used to treat the disturbance of porous cover.


Does the institution have retention ponds?:
Yes

A brief description of the institution's retention ponds:

UTSA has seven treatment basins used to treat storm water. These basins differ from retention ponds in that while designed to treat storm water they are designed with outflow. These treatment basins are calculated to provide an 80% reduction in the increase of total suspended solids from stormwater resulting from impervious cover. The basins are located in 4 sub drainage watershed basins to capture down gradient flow.


Does the institution have stone swales?:
No

A brief description of the institution's stone swales:
---

Does the institution have vegetated swales?:
Yes

A brief description of the institution's vegetated swales:

UTSA has seven treatment basins used to treat storm water. These basins differ from retention ponds in that while designed to treat storm water they are designed with outflow. These treatment basins are calculated to provide an 80% reduction in the increase of total suspended solids from stormwater resulting from impervious cover. The basins are located in 4 sub drainage watershed basins to capture down gradient flow.


Does the institution employ any other technologies or strategies for stormwater management?:
Yes

A brief description of other technologies or strategies for stormwater management employed:

UTSA uses maintenance protocols and spill protection to maintain the water quality from the UTSA grounds. UTSA also uses vegetated filter strips to treat some impervious cover not flowing to treatment basins.
