The City of Sierra Vista Public Works Department will conduct a controlled burn at the Environmental Operations Park on Tuesday, Dec. 13, or Thursday, Dec. 15, based on weather conditions.
The burn will be conducted in the morning and last until about noon. Controlled burns are part of annual maintenance for the City’s wastewater treatment facility. They reduce mosquitoes, clear dying vegetation to promote new growth, and aerate soil for the coming spring.
The Environmental Operations Park is located at 6801 Highway 90 and the burns sometimes produce smoke on the east side of Sierra Vista that can be seen from several miles away.
