TerraShield Mitigates Methane Risk For Residential Development

Case study highlights:

• Redevelopment of a 1.9-acre site into 34 three-story residential units
• Historical contamination from oil production and automotive repair activities

The project site, a 1.9-acre property in Huntington Beach, California, is being redeveloped into 34 three story residential units. Historically, the site was associated with oil production, including four abandoned oil wells, oil storage tanks, and automotive repair operations. The site required methane mitigation due to the potential for gas generation from historical oil field operations and organic-rich soils. Methane testing revealed concentrations exceeding regulatory thresholds, posing a potential risk to future residents. The redevelopment team prioritized addressing these challenges to ensure safety and regulatory compliance by designing and installing a proven and highly chemical resistant contaminant vapor barrier solution.
