The Historic Preservation Commission (HPC) of Gig Harbor is a crucial entity focused on the preservation of the city's historic properties. Established on June 12, 2023, by Ordinance 1513, the HPC comprises five members who evaluate proposed changes to properties listed on the local historic register. This commission not only makes decisions regarding these historic sites but also advises the city council on potential new listings. Gig Harbor is part of Washington State's certified local government (CLG) program, which is overseen by the Department of Archaeology and Historic Preservation, ensuring adherence to national preservation standards as mandated by the National Historic Preservation Act. The HPC holds quarterly meetings, with the schedule to be determined, and emphasizes transparency by making minutes and recordings of its proceedings publicly accessible.

The members of the HPC, including Jon Ashlock, Guy Hoppen, Libby Norris, Lucien Dhooge, and Eleanor Schroeder, are tasked with the significant responsibility of protecting the city's cultural heritage. By fostering community engagement and maintaining an open line of communication, the HPC plays a vital role in preserving Gig Harbor's historical integrity. The commission's efforts reflect the city's commitment to honoring its past while planning for the future.
