The Legislature further finds and declares that land within or adjacent to the Suisun Marsh should be acquired for public use or resource management, or both, and facilities suitable for such purposes should be constructed thereon, if the land meets one or more of the following criteria:
(a) It is suitable for passive recreational purposes such as fishing and nature observation and is located in the outer portions of the marsh near population centers or existing transportation routes, such as State Highway Route 12.
(b) It is suitable for the purpose of restoring areas to tidal action or to marsh or managed-wetland conditions and such restoration cannot be required as a condition of private development.
(c) It is suitable for providing additional wildlife habitat necessary to effective wildlife management, including consolidation of management units and improved public hunting opportunities. Acquisitions within this category should avoid privately owned property already managed as wildlife habitat unless offered for sale to the state.
