The Spokane River is the centerpiece for Spokane, but low flows reveal deep crevasses, creating pools in sporadic areas and an abundance of unsightly exposed river rock. Coffman helped Avista Utilities restore a section of the riverbed to re-establish its natural flow and aesthetics. We surveyed the simulated rock-shaped weirs to correct the flow and return the riverbed to its natural, more aesthetically pleasing state.
Coffman provided construction staking, erosion sediment control lead (CESCL) inspection, field audit reports, and as-builts for this project.
