Official Summary Text

AB 1102, as amended, Boerner.
Development projects: sea
Sea
level rise and groundwater
rise risk assessment.
rise: contaminated sites: report.
Under existing law, the Department of Toxic Substances Control generally regulates the management and handling of hazardous substances, materials, and waste.
The bill would require, on or before January 1, 2027, the department and the State Water Resources Control Board to submit a report to the Legislature that includes specified information, including information relating to all contaminated sites that are vulnerable to sea level rise and groundwater rise.
Existing law requires a public agency to compile one or more lists that specify in detail the information that will be required from any applicant for a development project, as defined.
This bill would require a proponent of a new development to complete a sea level rise and groundwater rise risk assessment as part of the application to a public agency if the proposed development will be within 1,000 feet of a contaminated site, as provided, and will be within an area vulnerable to groundwater rise or sea level rise, as defined. Because the bill would place additional duties on local agencies, the bill would impose a state-mandated local program.
The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
This bill would provide that no reimbursement is required by this act for a specified reason.
