AEW was retained by Trinity Property to attain environmental site closure requirement from SFDPH for an over 1,000 residential unit redevelopment project in San Francisco, California.  The redevelopment is being conducted in four phases.  AEW was tasked to perform site history review, soil and groundwater characterization of chemicals of concerns in the subsurface environment, and site mitigation plan to be implemented during and after construction for the phases of development.  The site mitigation plan proposed that no site remediation would be required with the exception of implementing appropriate waste management protocols, and environmental health and safety protocols for construction worker protection.  During the project, AEW maintained a strong working relationship with SFDPH and provided status on the progress of the project to SFDPH.  Because of communication established with SFDPH on this project, AEW was able to receive approval of the site mitigation plan and site characterization report within a few business days after submittal of the documents.  During the construction phase of the project, we assisted our client on waste profiling, delineating the extent of hazardous soil within the planned excavation area of construction, and disposal of the excavated material.  AEW prepared and assisted to implement a dust monitoring and control plan to comply with SFDPH’s dust control and monitoring ordinance, environmental health and safety plan, and storm water pollution prevention plan for the site during construction.  AEW also provided waste management and disposal support as well as dust and noise monitoring during construction.  After completion of the initial phase of the development, AEW was retained to provide similar environment services on the remaining two phases of development.  In addition, AEW conducted an updated Phase I ESA to assist Trinity Property for finalizing the construction financing with loan institutions.
