a new ebrpd master plan in 1980 fine-tuned the island's designation once more: it would now be "a regional shoreline to be operated under the regional preserve category". nevertheless, the early 1980s did see substantive progress. ebrpd and richmond formed a liaison committee and agreed to rework the land use development plan to incorporate the whole island, culminating in an environmental impact report (eir) that was presented in richmond in august 1984 and finalized in september 1985. this eir primarily analyzed ebrpd's proposed land use plan, which proposed ending hunting and opening the island to limited public access via a park-owned shuttle boat or private craft. the plan envisaged instituting controlled burns to maintain the balance of grassland and brush, placing a full-time caretaker on the island, using riprap to protect historic sites from erosion, and closing bird island and the west end of the sandspit to protect birds' nesting areas. the plan was to be funded from a 1984 statewide bond.
