• —•The HLAC presented to the Board of Supervisors on August 15, 2023, and recommended that the County adopt a Historic Preservation Ordinance, and provided the Board with a draft ordinance they had prepared. •The Board considered the recommendations of the HLAC, and referred the matter to the Transportation, Water and Infrastructure Committee (TWIC), and directed Department of Conservation and Development (DCD) staff to provide analysis on this item for TWIC’s consideration. •This meeting took place on February 24, 2025. •TWIC accepted the report and directed DCD staff to return at a future meeting with a report outlining a range of ordinance options, including input from other counties, potential cost recovery mechanisms, and how the ordinance would apply (e.g., to designated or contributing structures only). The Committee expressed general support for historic preservation but emphasized the need to balance these efforts with property owner rights. Concerns were raised regarding potential legal implications, staffing and cost impacts, and how such an ordinance would differ from or expand upon existing CEQA protections. •Staff will inform the HLAC when DCD anticipates reporting back to TWIC.
