FLAGSTAFF — The Schultz Creek Drainage Improvements Project at US HWY 180 has experienced delays from unforeseen developments in the relocation of existing utility lines. The project is now expected to be substantially complete by the last week of July. Road paving and landscaping will commence by mid-August.
The existing stormwater infrastructure at US Hwy 180 remains in place and will not be removed until the Drainage Improvements Project is complete. Flood risk to the area was significantly reduced in 2023 by the installation of detention basins upstream and the addition of a new 48-inch storm pipe near Fire Station No. 5. The current project will continue flood mitigation efforts by increasing the capacity of the culvert to accommodate a 100-year storm.
