This project develops a future condition model and updates priority subbasins with the latest watershed information. Priority subbasins are based on ultimate buildout land use and are defined as subbasins where mitigations and/or conservation needs to occur for the streams to meet future water quality standards. The products of this work are valuable in informing the community as to where Best Management Practices (BMP’s) need to occur. It is also beneficial to the various efforts that are being planned on the Upper San Antonio River watershed, such as the efforts on West Side Creeks, and Brackenridge Park.
Mission Reach Area Maintenance
Update (December 2025):
Crews will be moving south of Concepcion Park towards the baseball fields around the Mission Road area. The trail in this section will be closed the morning of Wednesday 12/10 and is expected to reopen the later next week.
Work will also continue at the current location near mile marker 8.2 for the remainder of the week, where crews will be cleaning the area and hauling off chips and debris. This section of the trail will remain open
When: Beginning October 20, 2025 through Spring 2026
What: Crews will be performing stem-density removal and related vegetation maintenance along sections of the Mission Reach to help manage flood risk and protect surrounding infrastructure. Some trails or segments may be closed temporarily while work is underway.
Why: Removing excess stems that naturally establish along the river helps maintain stormwater conveyance, reduces flood risk, and protects public infrastructure while allowing grassland and native vegetation to recover and thrive.
What to expect:
- Limited trail closures and intermittent work zones.
- Crews and equipment working near the riverbanks during daytime hours.
- Parking areas remain open, but visitors may see signage and temporary barriers.
