The San Antonio River Authority (River Authority) has announced that three schools have been selected to receive funds from the Watershed Wise Grant Program, which provides funding for schools to build on-site stormwater management projects using a variety of Low Impact Development (LID) methods. The River Authority received a total of 25 applications for the grants within the San Antonio River Watershed.

Following an internal review process, the selections were made, and an announcement was delivered to the chosen recipients: Bonham Academy, Earl Warren High School and Las Palmas Elementary School, all located in Bexar County.

“The quality of the applications has been impressive. The schools selected have displayed a regard for environmental health, and a desire to utilize an educational opportunity to learn more about stormwater runoff and onsite stormwater management” said Jacob Aalfs, landscape architect for the San Antonio River Authority.

Grants of up to $22,000 will be awarded to the winning schools to build LID features, also known as green stormwater infrastructure. In addition to enhancing the watershed’s ability to clean and improve stormwater before it reaches the river, a major goal for this program is to help educators address the issues of sustainability and non-point source pollution through hands-on, applied lessons with local students. Non-point source pollutants come from the air (pollen and dust), vehicles (oils, gas and rubber), roads/parking lots (oil, gas, rubber and dust) and lawns (herbicides, pesticides and bacteria).

Grant funds are applicable for design, construction, and installation of rain gardens, bioswales, cisterns, or a combination. The River Authority’s educators will provide in-class, hands-on, TEKS aligned presentations, lessons, and activities dedicated to the importance
of LID stormwater solutions for the grant-recipient schools.

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.
