LEGISLATIVE COUNSEL'S DIGEST
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.
The people of the State of California do enact as follows:
SECTION 1.
Section 57014 is added to the Health and Safety Code, to read:57014.
(a) On or before January 1, 2027, the Department of Toxic Substances Control and the State Water Resources Control Board shall submit a report to the Legislature that includes all contaminated sites that are vulnerable to sea level rise and groundwater rise and when the vulnerability assessment will be, or has been, completed.(a)A proponent of a new development shall 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 that has been identified by the Department of Toxics and Substances Control, the State Water Resources Control Board, or a local government and will be within an area vulnerable to groundwater rise or sea level rise.
(b)For purposes of this section, the following definitions apply:
(1)“Groundwater rise” means five feet of groundwater rise, as determined by the National Oceanic and Atmospheric Administration, the Ocean Protection Council, the United States Geological Survey, the University of California, or a local government’s coastal hazards vulnerability assessment.
(2)“Sea level rise” means five feet of sea level rise, as determined by the National Oceanic and Atmospheric Administration, the Ocean Protection Council, the United States Geological Survey, the University of California, or a local government’s coastal hazards vulnerability assessment.
(c)The risk assessment completed pursuant to this section shall be for informational purposes only.
No reimbursement is required by this act pursuant to Section 6 of Article XIII B of the California Constitution because a local agency or school district has the authority to levy service charges, fees, or assessments sufficient to pay for the program or level of service mandated by this act, within the meaning of Section 17556 of the Government Code.
