Harbor Bay 76 Station Closes – Here’s Why

On November 30, 2025 Simon Kim made the heartfelt decision to retire and close the 76 Service Station after serving the Community of Harbor Bay for 41 years. The decision was unrelated the the Harbor Bay Landing development project, but was instead prompted by a California mandate that underground fuel tanks have two protective shells to prevent soil or groundwater contamination. Harbor Bay’s 76 Station no longer meets the requirements of state law and Kim couldn’t afford to pay $2 million to replace them by January 1st, when the mandate went into effect.
