Coronado Public Services Department at 101 B Avenue manages street maintenance, parks, water service, sewer systems, and public facility upkeep across Coronado Island in the 92118 ZIP. The department maintains the sand replenishment and grooming schedule for Coronado Beach — a 1.5-mile shoreline ranked among the nation's top beaches — and the landscaping, irrigation, and playground-safety programs that sustain the island's 14 public parks. Water-system operations deliver potable water to every residential and commercial address on the island, with infrastructure that includes distribution mains, pump stations, storage reservoirs, and the metering systems that track consumption across the village, the Orange Avenue commercial corridor, and the Coronado Cays residential district. Sewer-system maintenance covers the collection network that conveys wastewater from every address in the 92118 ZIP to the regional treatment system, with preventive-maintenance protocols designed to avoid the sanitary-sewer overflows that pose environmental risk to Coronado Beach, Glorietta Bay, and San Diego Bay. Street maintenance crews resurface roads, repair sidewalks, maintain traffic signals, and manage the tree canopy that shades the village grid from Hotel Del Coronado and the resort district through the residential neighborhoods to the Coronado Bridge approach. The department coordinates with the City of Coronado Aquatics Center on pool-facility maintenance and with Recreation Services on the upkeep of city-operated venues including the Boathouse and Club Room at Glorietta Bay. Fleet maintenance, building custodial services, and the automated trash-and-recycling collection program round out a public-works operation that serves the island's compact geography where every home, business, and military family is connected by the flat, walkable village grid.
