VERTEX was retained to assist in the redevelopment of this early 1900s commercial and industrial property in the River North (RiNo) area of Denver, Colorado. The area was historically occupied by heavy industrial use, rail yard, commercial drycleaners, printing facilities, machine shops and other operations of environmental concern. The site was historically occupied by automotive repair/service facilities and industrial supply/machine shops. Additionally, the subject property is located within the Vasquez Boulevard and Interstate 70 Superfund/National Priority List region, Operable Unit-One.
The project included the completion of a review of prior subsurface investigations, performance of supplemental Phase II Limited Subsurface Investigations to further delineate prior findings, oversight of demolition and construction support consulting.
Based on the results of the subsurface investigations, on behalf of the client, VERTEX enrolled the subject property into the Colorado Department of Public Health and Environment (CDPHE) Voluntary Cleanup Program (VCP) to remediate the subject property of contaminants exceeding regulatory standards and demonstrate that conditions after remediation of the areas of concern are protective of human health and the environment based on the intended proposed use of the subject property.
As a part of the remedial action plan for Phase I of the Development, VERTEX prepared a Materials Management Plan for use during the redevelopment activities to ensure proper management, characterization and disposal of on-site soil and groundwater in accordance with local and state regulations. VERTEX oversaw and managed the soil excavation and disposal activities on-site which included the removal of coal-based, impacted fill material as well as petroleum impacted soil.
Upon completion of the remedial activities within Phase I of the Development, VERTEX prepared and submitted a No Action Determination (NAD) petition to the CDPHE for review, concurrence and issuance of regulatory closure.
The project was completed on-time and under budget. VERTEX’s consulting and guidance throughout the project provided the client with the ability to navigate complex on-site environmental issues, achieve and maintain compliance with local, state and federal regulations and maintain the project timeline.
