On Wednesday, October 16, the City of Phoenix and the Arizona Department of Forestry and Fire Management (DFFM) will conduct a prescribed burn at the Tres Rios Wetlands.
This collaborative effort aims to manage dense vegetation, restore vital riparian habitats, and provide Phoenix firefighters with essential wildfire response training.
Why the Prescribed Burn Matters
Phoenix’s Tres Rios Wetlands play a significant role in the city’s environmental restoration efforts. By maintaining a healthy ecosystem, these wetlands support wildlife diversity and help manage reclaimed water from the nearby 91st Avenue Wastewater Treatment Plant.
The prescribed burn, scheduled from 8 a.m. to 4 p.m., is designed to improve wetland health by:
- Reducing invasive plant species.
- Enhancing soil quality by recycling nutrients through controlled fire.
By integrating prescribed burns into their management plan, the city ensures the wetlands remain a thriving and sustainable habitat.
What Residents Should Know About the Burn
Road Closures and Traffic Impact
During the operation, 91st Avenue will be closed between the Wastewater Treatment Plant’s North Gate and Baseline Road. Traffic delays may occur along Broadway Road as fire crews manage the area and ensure safety. Residents should plan alternate routes or adjust travel times to avoid disruptions.
Visibility and Smoke Plume
Expect a visible smoke plume from southwest Phoenix and surrounding communities. The burn is planned to produce a controlled amount of smoke, but residents may notice its presence throughout the day.
The Arizona Department of Environmental Quality (ADEQ) and Maricopa County Air Quality Department (MCAQD) will monitor air quality to minimize any health impacts.
The Role of the Phoenix Fire Department
The Phoenix Fire Department will oversee the burn, ensuring it stays within the designated 50-acre area known as FRW-2. This controlled burn also serves as a vital training exercise for the department’s Wildland Urban Interface program.
Firefighters will receive hands-on experience, focusing on wildfire management skills such as:
- Wildland firefighting certifications.
- Incident command and drone mapping techniques.
This practical training is not only beneficial for the firefighters but also enhances Phoenix’s overall readiness for wildfire emergencies.
Environmental Benefits of Prescribed Burns
Prescribed burns are a critical tool in environmental management. By reducing fuel loads—dense vegetation that can cause more severe fires—these burns help prevent uncontrolled wildfires and promote ecosystem health.
The October timing is carefully chosen to avoid interfering with local wildlife breeding seasons, as outlined in the United States Fish and Wildlife Service Tres Rios Safe Harbor Agreement.
Why October?
October offers an ideal window for conducting prescribed burns, aligning with both weather conditions and environmental guidelines. The city’s careful planning ensures the burn maximizes its positive impact while minimizing disruptions to the ecosystem and local community.
Burn Area Map and Aerial Overview
Burn Zone Details |
Specifications |
|---|---|
| Location | FRW-2 Cell at Tres Rios |
| Area | Approximately 50 acres |
| Duration | 8 a.m. – 4 p.m. (tentative) |
| Air Quality Monitoring | ADEQ and MCAQD oversight |
The targeted burn area, FRW-2, covers around 50 acres. After the operation, crews will ensure safety by spraying the perimeter with water and monitoring air quality before releasing water back into the broader wetland system.
Community Engagement and Safety
Residents can play a part in ensuring a successful burn by staying informed and observing traffic advisories. The City of Phoenix provides updates through its official channels, and residents are encouraged to stay tuned for any changes in the schedule due to weather or other conditions.
By participating in these efforts, Phoenix residents help support crucial local ecosystems while contributing to community safety.
