Brownfield Development Success – Uptown Development – Traverse City, Michigan

Uptown Riverfront Development, is an upscale residential townhome and mixed-use (live-work) commercial development located on the Boardman River in Traverse City, Michigan. Grand Traverse County’s Brownfield Redevelopment Authority was awarded $800,000 in Community Development Block Grant funds from the State of Michigan for demolition/blight removal to segue for the redevelopment. Environmental investigations were conducted at the site as part of the purchase and redevelopment process. Chlorinated volatile organic compounds (CVOCs) were identified within the subsurface which appeared to be from historical operations at the site. These CVOCs were identified above Michigan Department of Environmental Quality (MDEQ) vapor intrusion screening levels. Therefore, as part of the Brownfield Redevelopment, a vapor mitigation system was determined to be necessary. Land Science assisted the environmental consulting firm, AKT Peerless, with the design of the system and provided both the vapor barriers (Geo-Seal®and Retro-Coat™) and subsurface ventilation (Vapor-Vent™) for the necessary buildings requiring mitigation systems at the site. The development is now nearing completion, with Phase 3 of the project to be completed by Spring 2017. Uptown Development TC, LLC’s, Project Manager, Mike Wills stated, “Without Land Science’s Geo-Seal and Retro-Coat vapor barriers, our redevelopment of a downtown Traverse City, Michigan Brownfield Site into upscale residential townhomes would have been impossible”.

Land Science’s team of vapor intrusion experts have provided vapor intrusion and mitigation solutions at numerous sites across the nation. See more successful case studies including award winning and nationally recognized Brownfield sites, industrial, commercial, and residential developments.

Geo-Seal® and Vapor-Vent Approved to Protect Urban School Complex from Harmful PHC and cVOC Contaminants

Project Highlights

  • Geo-Seal® applied to 40,000 square feet of new construction
  • Geo-Seal and Vapor Vent approved by California Department of Toxic Substances Control

Project Summary

A former manufacturing facility site in Oakland, California was contaminated due to years of engine repair, vehicle maintenance and fuel storage that took place on the property. The site is currently being used as a school complex and the Oakland Board of Education approved construction of a modern facility. However, after a site assessment was completed, it was determined that high levels of petroleum hydrocarbons, PAHs and chlorinated solvents were present.

Ninyo and Moore prepared a Removal Action Work Plan and Operation and Maintenance plan for approval by the California Department of Toxic Substances Control. An excavation remediation plan was implemented on-site to dispose of the majority of the contaminated soil and groundwater. A vapor mitigation system was utilized to avoid any potential inhalation risk that remained. Geo-Seal and Vapor-Vent were applied to 40,000 square feet of new construction to mitigate the vapor intrusion risk and meet regulatory requirements.
