Long Beach Unified School District
Signal Hill, CA
Location, Location, Location. The location fits the neighborhood need for a new school, but the site faces subsurface challenges.
The Leighton Solution.
Leighton was asked by the District during construction to take-over the methane mitigation. As time was of the essence, several technical personnel were immediately assigned to the project which required significant onsite training and familiarization.
Our services also included assuming responsibilities for system operations and maintenance for a five year monitoring program, with 24-hour per day availability to respond to system alarms.
Leighton has been responsible for the final system adjustments, system function checkout, documentation, and preparation of the Sampling and Analysis Plan (SAP) which includes an addendum to the Operations and Maintenance Plan (O&M Plan) prepared by the system design team. Leighton has prepared responses to DTSC’s comments and provided Agency to District liaison services.
