Home Browse Search

i . i The Corley Landfill Sediment Placement project will excavate between 11,000 and 12,000 cubic yards of dry sediment from the City's Oakley Sediment Basin and haul it to the Corley Landfill. The dry sediment will be spread over a portion of the 11 acre landfill site to a depth of 9". Sufficient grant funding is not available to cover the entire landfill site but the project will use the entire available grant funding to cover as much of the site as possible. This project was originally included as an alternate to the Basin 1 through 4 lake dredging project however the bid was unacceptably high at $372,680. The Corley Landfill Sediment Placement project was rebid as a separate project to be more in line with available grant funding.
