Title
Third Amendment to the Contract for Architect-Engineer Consulting Services for Old Landfill (B)
Explanation
The long closed Airport Landfill has exposed landfill waste over a large area along the south edge similar to the old landfill at Sweetwater Branch that is currently having the required 18 inches of cover restored. The consultant's task, as defined within the proposed amendment, is to develop documents that can be used for submitting to the Florida Department of Environmental Protection that demonstrates a comprehensive plan for covering the exposed materials and can also be used by contractors to implement the plan for the Airport Landfill.
Poor soil material and natural erosion caused by improper stormwater management are the contributing factors for the waste that is currently exposed. The envisioned plan will improve the quality of the cover material so that it encourages vigorous root growth and includes the best management practices for stormwater management. These elements of the work are expected to greatly reduce the potential for the waste from becoming exposed for approximately 20 years. Timing is important on the implementation of this effort. The Depot Park project will generate about 9,000 truckloads of dirt, which could be utilized as cover for this landfill project.
Fiscal Note
Funding is available in the Solid Waste Fund for this activity.
