CR 817, Lee Road, and South Sweetwater Road Widening

Douglas County, GA ESA Phase I and Phase II

MC Squared (MC²) is supporting Lowe Engineers on a roadway widening improvement project along CR 817, Lee Road, and South Sweetwater Road in Douglas County, Georgia. The project aims to improve traffic flow and safety through expanded roadway capacity and infrastructure upgrades. Before design and construction can proceed, a thorough environmental assessment is required to identify and mitigate potential risks.

Our team was engaged to perform a Phase I Environmental Site Assessment (ESA), which involved reviewing historical land use records, regulatory databases, and conducting a site reconnaissance. 

During this assessment, we identified multiple underground storage tank (UST) sites in close proximity to the project limits, including two active tanks located directly adjacent to the planned alignment.

Due to these findings, the project advanced into Phase II ESA fieldwork. Our environmental professionals are conducting subsurface investigations, including soil and groundwater sampling, to evaluate potential contamination and determine whether further remediation or monitoring may be required. The data collected will support environmental compliance and inform planning decisions ahead of project development.

MC² is proud to deliver detailed, data-driven evaluations that support responsible infrastructure improvements. Our work on this project helps ensure safety, sustainability, and regulatory alignment for long-term development in Douglas County.

Utoy Creek WRC Influent Pump Station, Fulton County GA

MC Squared collects soil samples at Utoy Creek RFC

MC Squared is supporting Wade Trim and Fulton County in upgrading the influent pump station at the Utoy Creek Water Reclamation Center. MC Squared provides geotechnical engineering services throughout the design and early construction phases. Our team conducted site investigations to evaluate subsurface conditions, including soil behavior and groundwater levels, which are vital for planning stable, long-lasting foundation systems. We also assist with stakeholder coordination and provide geotechnical insights to help guide demolition planning and phased construction activities.

Caloosahatchee River West Basin Storage Reservoir (C-43 WBSR)

Developed by C-43 Water Management Builders for the South Florida Water Management District (SFWMD) and U.S. Army Corps of Engineers (USACE), the C-43 West Basin Storage Reservoir is a 170,000-acre-foot infrastructure project designed to store excess freshwater from the Caloosahatchee River, stabilize salinity levels, and prevent algal blooms. MC Squared provided critical laboratory management, construction materials testing, and quality control, ensuring compliance with USACE standards. Our contributions—including testing 22 million cubic yards of embankment, 110,000 tons of soil-cement armoring, and 19 miles of soil-bentonite cutoff wall—have helped ensure the reservoir’s durability, reliability, and long-term impact on Florida’s water resources and communities.

Custer Avenue CSO Relief Storage Vault City of Atlanta, Fulton County, Georgia

Provided comprehensive geotechnical engineering services for the Custer Avenue CSO Relief Storage Vault project which were performed in two Phases. We evaluated the soil conditions and groundwater levels at the site, and provided recommendations concerning site development and foundation design and construction recommendations for the proposed storage vault. The proposed vault is a new five (5) million gallon buried underground stormwater vault retention consisting of cast-in-place concrete with side walls, overflow weir and box culvert by-pass to storage vault. The foot print of the vault is 58,000 square feet, City of Atlanta, Georgia.

Connally Storage Vault City of Atlanta, Fulton County, Georgia

Provided comprehensive geotechnical explorations, seismic study, and foundations evaluations and recommendations. Our recommendations consisted of deep foundations and shallow mat foundations. The project is a seven (7.0) million gallon (MG) buried underground stormwater vault retention consisting of cast-in-place concrete beams, columns with side walls, overflow weir and box culvert by-pass to storage vault. The foot print of the vault is approximately 90,000 square feet. In addition, we provided design recommendations for the proposed stormwater pond area which is approximately 780,000 square feet and is located on the SW corner of the intersection of Martin and Little Streets, Atlanta, Georgia.
