San Francisco: Maher Zone Compliance

In 2013 the City of San Francisco enacted legislation enlarging the area where mandatory soil and groundwater testing is required prior to site redevelopment activities. Commonly referred to as the expanded Maher Zone, properties throughout the City that (1) have the potential to contain hazardous substances, based on site histories that indicate prior use for industrial uses, gas stations, or any other uses associated with underground storage tanks or located within 100 ft. of any properties containing underground storage tanks, and (2) properties located within 150 feet of freeways. For such sites the property owner must prepare a land use history (Phase I ESA) and submit the findings to the San Francisco Department of Public Health (DPH) for review. DPH will require soil testing and/or groundwater investigation where appropriate. DPH will also require remediation where the investigation indicates the presence or absence of any one of the materials designated by DPH as hazardous.
