manufacturing plant in the United States at a site known as Glen Canyon Park, which started up on March 19, 1868. On November 26, 1869, there was an explosion that destroyed every building on the site (including the fence around the plant). The plant was forced to move farther away from heavily populated areas. Another explosion occurred at the Albany Hill plant in 1892, before Giant built its last plant in the lightly populated area of Pinole Point. Giant created a small unincorporated community, which it named Giant, California. Later, the Giant community became the established Croatian community of Sobrante."Listed California Historical Resources No. 1002-1.

Recent construction projects


Playground area

The playground at Point Pinole park was temporarily closed for construction from mid-August through October, 2017. During this time, the playground was resurfaced with wood fiber, equipment replaced with a net climber and a stand-up spinner, and a wheelchair-accessible path and picnic tables were added. All park paths remained open to the public during this work.


Atlas Road Bridge

On April 22, 2017, EBRPD dedicated the Atlas Road Bridge, a combination vehicle and wheelchair-compliant pedestrian bridge that connects to the San Francisco Bay Trail. This activity included building a new main entrance and parking area. The new entrance provides a bridge over active railroad tracks, which had been a hazard for pedestrians approaching the park from the parking lot. The project cost $11.7 million, which was largely funded by local bond Measure CC, the City of Richmond and grants from the following grantors: * California State Parks * California Natural Resources Agency * Contra Costa Transportation Authority The new bridge is part of a multi-phase project that will eventually lead to additional picnic areas, a new playground and the route to a new interpretive center for the park.


Dotson Family Marsh

At the same ceremony in April 2017, EBRPD also renamed and dedicated Breuner Marsh as the Dotson Family Marsh, honoring a family led by Reverend Richard Dotson, who had worked for many years to keep Breuner Marsh wild and open to the public, opposing several attempts to develop the tract for commercial ventures. Rev. Dotson was able to organize residents of his own neighborhood in Richmond, Parchester, reminding them that the builder of their houses had promised they would always have access to the bay. He also recruited the
