Preparing for Monsoons and Beyond

Stepping up to the challenge through stormwater maintenance 

Post Date: 04/29/22

You may notice a lot of work happening in our drainages this spring. The Spruce Wash Watershed is getting some major infrastructure improvements to lessen the impact of flooding in Flagstaff neighborhoods. Work is underway throughout the wash, beginning with alluvial fan restoration and sediment reduction by the Coconino County Flood Control District below the Museum Fire burn scar, downstream to the Park Sediment Basins Project, then channel improvements from Cedar Ave to Dortha Ave, a large concrete box culvert at Dortha Ave and regional detention basins at Killip Elementary School. You can get updates on these projects at the Museum Flood Projects webpage. Collaborations with the Flood Control District, as well as state and federal agencies to mitigate damage from floods will continue into the future.  

Channel Maintenance 

Since summer 2021, we have been systematically clearing drainages, ensuring the infrastructure is prepared to handle monsoon season and beyond. Our GIS Management System has tracked over 740 closed-channel conveyance systems (pipes, culverts, basins) cleaned out since July, as well as cleanings and improvements in over 55 open-channel drainages, resulting from 139 inspections. Work can be followed on the Stormwater Maintenance Map.
