DATE: February 20, 2024
SUBJECT
Consider adoption of an ordinance of the City of Denton, a Texas home-rule municipal corporation,
authorizing the City Manager to execute a contract with Hammett Excavation, Inc., for the Moseley Road
Landfill Erosion Maintenance Project for the Solid Waste Department; providing for the expenditure of
funds therefor; and providing an effective date (CSP 8354 – awarded to Hammett Excavation, Inc., in the
not-to-exceed amount of $1,156,005.17).
INFORMATION/BACKGROUND
The Moseley Road Landfill, Texas Commission on Environmental Quality (TCEQ) Municipal Solid Waste
(MSW) Permit 13, is located in the City of Crossroads on City of Denton-owned property. The Landfill
began accepting waste in 1961 and was closed in 1984, and a soil final cover system was installed. The
landfill permit was canceled after a five-year post-closure period, common for landfills from this generation.
The Landfill cover has native vegetative growth, and no erosion control measures in place. There is severe
erosion along the west slope and channelization on the slope that was caused by preferential flow paths in
areas of differential settlement within the waste mass. The west slope has two significant erosion gullies,
the largest of which is approximately 50 feet wide and 15 feet deep when measured vertically. Final cover
maintenance/repair is required to retain the erosional integrity of the Landfill and prevent these conditions
from reoccurring.
The proposed project involves the repair of erosion damage to the final cover system on the west side slope
of the landfill and the installation of soil reinforcement to reduce future erosion to the landfill cover system.
The Moseley Road Landfill Erosion Maintenance Project has a total estimated cost of $1,156,005.17. This
estimate includes a $1,100,957.30 total base proposal amount and a five 5% contingency of $55,047.87.
The contingency allowance is for the sole use of the City and will be subject to written by the City’s Project
Manager.
The Solid Waste Department’s capital improvement program (CIP) provides funding for the excavation and
construction of this project. The City and the engineering firm of Parkhill completed the design services
agreement in June 2022 to provide services related to design, construction, quality assurance, and regulatory
approval.
Competitive Sealed Proposals were sent to 1,000 prospective suppliers of this item, including 72 Denton
