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.

Questions? Call the San Antonio River Authority at (210) 227-1373 or visit https://www.sariverauthority.org/services/river-health/ecosystems/.

Thank you for your patience while we keep the Mission Reach safe, clean, and enjoyable.
