Coronado MainStreet at 826 Orange Avenue, Suite 635, 92118, is a nonprofit organization dedicated to supporting the economic vitality and historic character of the Coronado business district centered on Orange Avenue. The organization promotes local businesses, organizes community events like the annual Coronado Flower Show and holiday parades, and advocates for the long-term health of the commercial corridor — working alongside the Coronado Chamber of Commerce at 1125 10th Street on business advocacy. For the historical preservation side of that mission, the Coronado Historical Association at 1100 Orange Avenue documents the island's architectural and civic heritage.
