On August 14, 2019, PG&E contractors began work associated with the maintenance of an existing groundwater extraction and treatment system, located primarily on the southern parcels of the BioMarin campus at the San Rafael Corporate Center. The system is part of the remedy for the 17-acre former manufactured gas plant/San Rafael Service Center site. Work will occur over the course of approximately six days, spaced over the months of August, September, and October. This project entails curing a manufactured fabric liner using high-heat, within a 250-foot section of a City water pipeline which is located in the right-of-way on Lindaro Street, north of Andersen Drive. There will be an odor associated with curing the fabric liner resin, which will be partially masked with a bubblegum-like odor additive. For majority of the work, crews will need to close the sidewalk and some parking spaces on the east side of Lindaro Street. Additionally, the northbound lane of Lindaro Street will be closed to traffic for two to three days in mid-to-late September to allow crews to safely install the pipeline liner. During this time, vehicles will be routed onto Andersen Drive to either 2nd Street or Irwin Street and Lincoln Avenue. Traffic signage and flaggers will be present throughout to safely guide vehicles around the work area. All work is being conducted under the oversight of the San Francisco Bay Regional Water Quality Control Board and the City of San Rafael.
