The City of Longmont will conduct a drone application of sulfentrazone to the east hills at Sandstone Ranch Nature Area from approximately 10 am to 2 pm on Friday, December 13. During that time, all trails east of the main paved trail will be closed to the public and staff that are not directly involved with the mission.

If you have questions, or would like to request a PDF map of the area, please contact City of Longmont Ecosystem Manager Jim Krick at 303-651-8451.
