Oil Field Redevelopment - Villages at Heritage Springs

Project Manager: Nancy Beresky

Oil Field Redevelopment - Villages at Heritage Springs

Waterstone was retained by the City of Santa Fe Springs to research the feasibility of residential redevelopment on a 54-acre piece of the Santa Fe Springs oil field. After Waterstone prepared the feasibility study and cost options for remediation, Waterstone was retained to perform an extensive investigation including soil sampling, vapor sampling, and groundwater sampling at over 100 areas of concern for a group of entities consisting of the City, the oil company, and the developer. After site characterization was complete, Waterstone prepared a Remedial Action Plan including a risk assessment to define the 39 areas of concern that required remediation. Waterstone performed 72 days of remediation by excavation, removing 75,000 tons of soil from former sump and tank farm areas. Waterstone collected confirmation samples and used these in a final risk assessment to demonstrate that the site was suitable for residential development. All work was conducted under the regulatory oversight of the local Certified Unified Program Agency (CUPA) with additional oversight by the Regional Water Quality Control Board (RWQCB) and the Office of Environmental Health Hazard Assessment (OEHHA). The site has been successfully redeveloped as the Villages at Heritage Springs residential neighborhood.
