Fisher Creek Detention Basin Expansion Project

Fisher Creek Detention Basin Expansion Project

To meet future detention and retention needs of the City in the Coyote Creek Watershed area, based upon new estimates of future rainfall load, the City desires to excavate approximately 10 feet of material out of the existing basin to increase the depth from 13.7 feet to 23.7 feet, and introduce more storage capacity. The project would excavate approximately 50,000 cubic yards (CY) of soil over the course of five weeks. This material would be excavated from the toe of the slopes, an area of roughly 2.77 acres, rendering the basin bottom 10 feet lower than the existing elevation. The proposed project would result in the removal of 56 trees on site, including 37 red willows and 19 Fremont cottonwoods. Materials from the excavation would be disposed at the Kirby Canyon Landfill or, if determined appropriate to serve as construction fill, sent to a development site in the City in need of surplus soil, which would reduce the length of trips (compared to Kirby Canyon) needed to deposit and dispose of the dirt this summer. Construction activities would occur from 7 am to 5 pm on weekdays utilizing one large excavator, one dozer, and one grader on site.
