Bay Area Redevelopment Portfolio
Since 2019, Citadel EHS has supported a private real estate developer with environmental due diligence services for approximately 25 properties across the Bay Area targeted for purchase and redevelopment into commercial and/or residential uses. These services were designed to assess potential environmental risks, facilitate cost modeling, and streamline regulatory compliance before acquisition and redevelopment.

DTSC Cleanup in Vulnerable Communities Initiative
As part of the California Department of Toxic Substances Control's (DTSC) Cleanup in Vulnerable Communities Initiative (CVCI), Citadel EHS provided Phase I Environmental Site Assessments and Discovery Investigations (DIs) for a portfolio of former and current dry cleaner sites throughout the San Francisco Bay Area. The project involved the environmental assessment of commercial and/or residential property historically used for dry cleaning operations, which is a recognized environmental concern due to the historical use of tetrachloroethene (PCE).
Oakland Affordable Senior Housing
Citadel EHS manages the investigation and remediation of a 0.64 acre commercial property in the City of Oakland within Alameda County. The site is an Equitable Communities Revitalization Grant (ECRG) environmental investigation project under the oversight of the Department of Toxic Substances (DTSC).
1000 Sutter Street UST Closure
Citadel EHS helped guide a complex underground storage tank environmental case at 1000 Sutter Street in San Francisco through investigation, corrective action, and ultimately regulatory closure. The case involved historical releases associated with former heating-oil USTs beneath and adjacent to a long-established urban property, requiring investigation of soil, groundwater, and soil vapor conditions within the constraints of an existing building, sidewalk, utilities, and surrounding development.
