USFS Museum Fire Sediment Reduction Project

What's New...

April 28, 2022: The National Environmental Policy Act (NEPA) process has been completed and work on the project is underway. 

This week's work commenced on the lower North Tributary of the Spruce Ave Wash on forest and included the construction of rock, grade-control structures. Work on the West Tributary and Paradise Fan locations on forest are anticipated to begin this week and next week.

Project Description

The Museum Fire Sediment Reduction Project includes grade stabilization and watershed restoration work to reduce sediment production and transport on USFS land above and below Mt. Elden Estates. 

Watershed restoration measures like these are necessary to reduce the level of sediment leaving the burn area, as well as erosion occurring downstream, and impacting the Mt. Elden Estates and Lockett Ranches areas and the Paradise, Grandview, and Sunnyside neighborhoods in Flagstaff. Without a reduction in these very high levels of sediment, any expansion of the floodwater conveyances within the city will not be effective at reducing the level of floodwater impacting homes because it will quickly fill up with sediment.
