Downtown Redevelopment Cleanup

The Project.

In order to help facilitate the construction of a large redevelopment project in downtown San Diego, our client needed to assess and remove several thousand feet of underground fuel pipeline that was present in the area of redevelopment and in the public right-of-way. The pipeline passed several areas of known contamination and were immediately suspect if contamination was encountered in the vicinity of the trace of the pipelines.

The Leighton Solution.

In a project management role, Leighton’s team acted as an extension of their staff to provide financial projections and monitoring of the project schedule and budget. The client’s technical approach to site remediation is effective and unique by utilizing teams of internal and external experts. Leighton’s technical role was to monitor activities of the team and provide comprehensive reporting and technical peer review of all groundwater remedial activities.

The project team includes experts in treatment system design and installation, permitting, groundwater monitoring, system operation and maintenance, agency compliance, groundwater plume delineation, and coordination with onsite property owners and business operations.

The offsite plume investigation includes the installation of dual- and triple-nested wells in the Gage Aquifer equivalent and Bellflower Aquitard. More than 50 onsite and offsite groundwater wells were used to monitor groundwater flow and chemical concentrations, and to collect groundwater remediation performance data.
