Owner Objective
Development Management, Inc. (DMI) is a high-quality real estate development company with a primary focus on grocery-anchored properties and storage centers. DMI currently manages storage centers in Winston-Salem, North Carolina, Charlotte, North Carolina, Tega Cay, South Carolina, and Myrtle Beach, South Carolina, with future locations in Raleigh, North Carolina, Charlotte, North Carolina and Pawley’s Island, South Carolina.
DMI was seeking assistance with environmental services for Brownfields redevelopment of the Powers Site in the South End district of Charlotte in order to redevelop the site for two commercial storage unit buildings with associated parking. The property was previously utilized as an automotive junkyard that included an auto repair garage. A portion of the site is underlain by an abandoned rock quarry within which coal tar waste produced by turn-of-the-century coal gas production was deposited.
CEC Approach
CEC was hired to provide environmental due diligence (Phase I and II Environmental Site Assessments) related to the purchase of the site. CEC also assisted DMI in determining the eligibility of the under-utilized property in the North Carolina Department of Environmental Quality Brownfields Program and its subsequent assessment and environmental management. CEC prepared and implemented a Brownfields Assessment Work Plan to characterize site environmental conditions and evaluate the risks of exposure. Abandoned drums were characterized and removed for off-site disposal and polycyclic aromatic hydrocarbons (PAHs) and arsenic were identified at concentrations above the applicable non-restricted soil cleanup criteria in on-site fill material, which are related to past automotive salvage and disposal of coal tar and foundry casting sand wastes.
CEC developed an Environmental Management Plan that outlines the engineering and administrative controls appropriate for management of identified impacted soil and debris, as well as potential unknown contaminated materials, that will be displaced during site redevelopment. CEC will provide on-site oversight of environmental-related site redevelopment activities.
Due to identified methane concerns, CEC has been engaged by the developer to address potential building methane intrusion risks by designing a sub-slab methane mitigation system utilizing a membrane barrier impervious to methane intrusion.
CEC assisted DMI in entering the subject property into the NCDEQ Brownfields Program and is providing consulting services with subsequent Brownfields assessment and environmental management during site redevelopment. Phase I site construction is scheduled to start September 2018 followed by Phase 2 to be completed by 2022-2023.
