Mesquite
Regional Landfill
County of Imperial, CA
LandMark Consultants, Inc.
provided geotechnical engineering services for the proposed
Mesquite Regional Landfill in Imperial County, California. The
Mesquite Regional Landfill (MRL) site is located at 6502 East
Highway 78, approximately four miles northeast of Glamis,
California. The proposed landfill will be located on 4,245 acres
of vacant land adjacent to the Mesquite Gold Mine. It will be a
Class III landfill accepting residual municipal solid waste (MSW)
that will be rail hauled from southern
California
communities. The approved landfill footprint is about 2,290 acres
and will provide capacity for approximately 600 million tons of
residual MSW over an estimated 100 years of disposal operations.
Landmark prepared a
geotechnical investigation report for the landfill water system
improvements which consist of two electrical substations and
approximately 5,000 linear feet of 12 to 18 inch diameter
underground water pipeline between an existing above ground steel
pipeline and a new 2 million gallon steel water storage tank.
Landmark Consultants provided
construction materials testing and inspection services during
construction of the infrastructure for the MRL. Landmark provided
asphaltic concrete pavement, concrete, and soil-cement testing
services for the project. We also provided soil-cement mix
designs. The infrastructure improvements portion of the project
consisted of 130,000 cubic yards of soil cement, 30,000 tons of
crushed aggregate base and 30,000 tons of asphaltic concrete.
Infrastructure work consisted of installation and backfill of
about 3,900 linear feet of watermain, 400 linear feet of
electrical conduit, placement of a standby generator slab, a
pressure tank slab and a 40 ft. x 80 ft. pump foundation and steel
shade structure.
