6315.
(a) For the purposes of this section, “a local trustee of granted public trust lands” means a county, city, or district, including water, sanitary, regional park, port, or harbor district, or any other local political or corporate subdivision that has been granted public trust lands through a legislative grant.(b) Notwithstanding any other law, a A local trustee of granted public trust lands shall give management priority to, and take all reasonable actions that are necessary for, the preparation of a sea level
action plan pursuant to this section for all of its legislatively granted public trust lands.
(c) The plan shall be prepared by July 1, 2011 2012, and in consideration of, and using relevant information contained in, the 2009 California Climate Adaptation Strategy prepared by the Natural Resources Agency, the Report on Sea Level Rise Preparedness prepared by the State Lands Commission and any subsequent updates to that report, and any other related resource. The plan shall include all of the following:
(1) An assessment of the impact of sea level rise on granted public trust lands.
(2) Maps showing the areas that may be affected by sea level rise in the years 2050 and 2100. These maps shall include the potential impacts of 100-year storm events. A trustee may rely on appropriate maps generated by other entities.
(3) An estimate of the financial cost of the impact of sea level rise on granted public trust lands. The estimate shall consider, but is not limited to, both the potential cost of repair of damage to and value of lost use of improvements and land and the anticipated cost to prevent or mitigate potential damage.
(4) Strategies to prevent or mitigate damage to existing development and infrastructure, and to protect and enhance undeveloped, vulnerable shoreline areas containing critical
habitat and opportunities for habitat creation, including wetland restoration, habitat migration, or the creation of buffer zones on granted public trust lands. When developing these strategies, especially along the coastline, a grantee shall consider feasible, nonengineered measures, such as beach
replenishment, coastal setback lines, and managed retreat of structures.
(5) Design standards that would avoid or mitigate impacts to new development and infrastructure.
(6) Implementation measures and timetables.
(d) In preparing a sea level action plan, a local trustee shall conduct at least one public hearing and consult with its lessees, local, state, and federal agencies, and other users of the granted public trust lands.
(e) A copy of the plan shall be submitted to the Natural Resources Agency, the Governor’s Office of Planning and Research or its
successor agency, and the State Lands Commission.
(f) The commission may exempt a local trustee of granted public trust lands from this section or allow a local trustee to submit a modified sea level action plan if the commission finds either of the following:
(1) None of the local trustee’s public trust lands is subject to sea level rise by 2100.
(2) The cost to provide the plan substantially outweighs the benefit the plan would have in preventing the potential economic and environmental harms associated with sea level rise on the local trustee’s granted public trust lands.
(g) The commission shall exempt a local trustee of granted public trust lands from this section or
grant a deadline extension, if the revenues derived from its granted public trust lands and assets subject to subdivision (b) of Section 6306 or funding made available to it from sources such as the Ocean Protection Council are not sufficient to pay for the cost of developing the plan.
