ADOT Completes Work To Increase Stormwater Capacity And Reduce Flooding Along Highway 180 Along Schultz Creek

Work to increase the capacity of the stormwater drainage system along Highway 180 in Flagstaff has been completed, according to ADOT.  Heavy runoff from a record-setting snow season earlier this year exposed damage to an existing drainage pipe parallel to the highway, between the Schultz Creek culvert and Stevanna Way, which is below the Pipeline Fire burn scar.  ADOT and the City of Flagstaff collaborated on an accelerated project to repair the existing drainage pipe and add a second nearby 48-inch interim pipeline. Flagstaff provided an easement for the new pipeline.  ADOT district administrator for ADOT’s northwest district, Brenden Foley says “we need to emphasize that these are interim improvements,” He adds, “the new line provides an important increase in the system’s drainage capacity while Flagstaff plans for future capacity improvements. We appreciate the city’s help on this project.” Stormwater damage had caused sections of the ground above the old pipeline parallel to southbound US 180 to sink. Repair work included installing a new pipe and pavement and the replacement of a sidewalk and driveways, including those in front of Flagstaff Fire Station Number Five.  Flagstaff Mayor Becky Daggett says the project “involved collaboration and accelerated action on behalf of neighborhoods in the area.”  She adds, “our team is already working on the design for a permanent drainage system that will handle much more runoff.”  This adds to detention basins that were constructed and mitigation work that was done above the neighborhood along Schultz Creek.
