Gilleland Creek Stormwater Retrofit, 2014
The University of Texas modified a stormwater retention basin with the goal of reducing targeted pollutants by 50%. See photos of the basins.

In 2013, the Austin City Council passed a comprehensive overhaul of the city's Watershed Protection Ordinance . At the core of the ordinance are three interrelated changes: better stream buffers, improved floodplain protections, and new erosion hazard provisions. The ordinance extends creek buffers—setbacks to ensure that development is not built too close to waterways—for over 400 miles of smaller “headwaters” streams.

On August 14, 2012, the Travis County Commissioners’ Court approved requirements to establish stream setbacks applicable to development in all unincorporated areas of the watershed.
