Cal. Pub. Res. Code § 6210.9

If the commission has public land, including school land, tide or submerged lands, and lands subject to the public trust for commerce, navigation, and fisheries, to which there is no access available, it may, in the name of the state, acquire by purchase, lease, gift, exchange, or, if all negotiations fail, by condemnation, a right-of-way or easement across privately owned land or other land that it deems necessary to provide access to such public land.
