The Presidio, a former military post south of the Golden Gate Bridge, is now a collection of historical buildings and open space parkland spanning nearly 1,500 acres and is managed by the Presidio Trust.
The trust has proposed to build a museum housing Gap Inc. founder Don Fisher's contemporary art collection and a lodge on the grounds of the Presidio's Main Post, hoping to establish the area as a cultural and community center.
Critics of the plan have complained about the size of the proposed buildings and the traffic the new complex is likely to bring to the area. They claim the proposal would harm the historical character and natural beauty of the Presidio.
The trust on Friday announced an amended proposal that includes limiting the height of the new buildings and reducing the development's impact on archaeological resources.
Members of the Presidio Historical Association, one of the groups opposing the plan, have since responded that the new proposal has many of the same problems as the prior one.
The Presidio Trust will hold a 6:30 p.m. hearing to take public comment on the proposal at the Palace of Fine Arts Theatre, 3301 Lyon St.
The Presidio Historical Association has scheduled a news conference outside the theatre before the meeting, at 5:15 p.m.
