PHOTO: The City of Flagstaff has secured $2.4 million from a federal grant to begin flood mitigation work in west Flagstaff. The area has been inundated several times in recent weeks as a result of heavy rain over the Pipeline Fire scar. Three large detention basins will be built at the intersection of Elden Lookout Road and Schultz Pass Road on a 20-acre city parcel commonly known as the Y. The tiered earthen basins will be designed to temporarily hold and gradually release water that flows down the Schultz Creek drainage and have a capacity of more than 50 acre-feet, or about 16.3 million gallons. "So essentially instead of one giant catastrophic flood, you should see several hours of flow going through the channel. But it’s flow that the downstream system can accommodate," says City of Flagstaff stormwater manager Ed Schenk.
