Document Description
The Department of Toxic Substances Control (DTSC) has approved a Removal Action Workplan (RAW) associated with the Prima Development Senior Mixed-Use Project located on an approximately 1.33-acre parcel in the city of Cudahy (Site). The Site is currently vacant and is planned for redevelopment with a six-story mixed-use building containing subterranean parking, commercial lease space on the first floor, and senior housing apartment units on the upper five levels. The RAW was prepared to address potential effects from contaminants in the soil vapor at the Site, and the remediation activities identified in the RAW consist of the installation of a Vapor Intrusion Mitigation System (VIMS) and the recordation of a Land Use Covenant (LUC).
• Vapor Intrusion Mitigation System (VIMS): The VIMS includes installation of a subsurface vapor membrane and a passive ventilation system with the option to convert to active ventilation beneath the future building. The vapor membrane will be a chemically resistant, spray-applied membrane installed over prepared substrate. The vapor capture piping network will be placed in a sub-slab gravel layer which provides permeability to collect gases for venting to exterior vent risers located throughout the building. The venting system includes six ventilation risers, with each vent riser terminating approximately 18 inches above the building roof. Active venting, if needed, would require installation of blowers on the roof of the building at select vent risers to actively discharge subsurface vapors at a rate of up to 100 cubic feet per minute (CFM). Gas mitigation system design drawings will be prepared during the design phase of Site development and are required to be submitted to the DTSC for review and approval prior to installation.
The installation of the vapor membrane and venting equipment would occur as part of the construction of the mixed-use senior development.
• Land Use Covenant: A LUC will be recorded on Title to inform future Site owners about Site conditions and prohibit activities that will disturb soil at the Site (e.g., excavation, grading, removal, trenching, filling, earth movement, mining, or drilling) without a Soil Management Plan (SMP) pre-approved by DTSC in writing. LUC inspection and reporting requirements, including annual inspections and Five-Year Reviews, will be included in the separate Operations and Maintenance Plan.
