Converting Property from Agricultural to Residential


New clients trusted Farallon to coordinate remediation of soil contamination at a residential redevelopment propery. 

Farallon is negotiating regulatory closure for a property with historical pesticide releases to soil, allowing the clients to redevelop the property as planned, with minimal exposure to potential future environmental liability.

Farallon was engaged to help a developer remediate contaminated soil at property formerly used as a plant container nursery. Farallon conducted an initial investigation to delineate the extent and magnitude of organochlorine pesticide contamination in shallow soil. The second phase of investigation, to verify that the contamination did not extend to wetland and riparian areas of the property, was performed concurrently with initial redevelopment earthwork and construction activities.

Farallon maintained close daily communication with contractors to ensure project success and resolve issues related to unanticipated and/or rapidly changing conditions on the property. Over 12 tons of pesticide-contaminated soil was excavated, hauled from the property, and disposed of at an approved facility, eliminating the future residents’ potential exposure to pesticides associated with the former use of the property.

“The challenges presented by rapidly changing Site conditions and construction schedules were overcome through clear and concise communication with the client, contractors, and Farallon personnel on a near daily basis,” said Project Hydrogeologist Paul Garvin, who managed the project. “Thanks to clear communication with regulatory agencies and extensive project documentation, Farallon project managers and field personnel have led the project on a clear path toward regulatory case closure for the client.”
