In 1994, the Army turned the Presidio over to the national park system. And in doing so created one of the finest public spaces in SF and California. Originally founded approximately 1776, there are now plans to renovate some key sections of the Presidio, including the greening of what is now a parking lot, but what used to be called the Parade Ground. Along with building a tunnel for the Doyle drive approach to the Golden Gate bridge. The Parade grounds are lined by Barracks, which are mostly offices and at the southern edge where Donald Fisher wants to build a museum.
The tunnel plan is really interesting as it will connect the western edge of the Parade Grounds with the beachfront at the west end of Chrissy Field, whereas today if you were to walk from the parade grounds to the beach you would walk under the Doyle drive approach (it’s elevated freeway). This would also create some nice beach views from the newly recreated Parade grounds.
Funding? From what I’ve read it’s not fully evident where the money comes from. The current docs state:
To achieve its mission, the Trust generates revenues by leasing the park’s buildings. Federal appropriations diminish each year and will cease at the end of fiscal year 2012. The Trust uses these sources of funding to operate the park and undertake necessary capital improvements.
