When another local public agency is unable or unwilling to take title to an area required for public access to and along the coastline, the department or the conservancy may accept title to such an area. The department or the conservancy, however, shall not be required to open any area for public use when, in its estimation, the benefits of public use would be outweighed by the costs of development and maintenance. The department or the conservancy shall make a determined effort to identify local public agencies and nonprofit organizations which will accept responsibility for maintenance and liability for public accessways which are located outside of the state park system. The department or the conservancy may lease any public access site to a public agency or nonprofit organization; provided, however, that the conditions of such transfer guarantee public use of the site for access to coastal resources.
