A resource enhancement plan prepared for a project to be carried out directly by the conservancy as provided in Section 31263, shall, before any lands are acquired or other implementation actions taken, be submitted to the local public agency which exercises land use regulation over the area of the proposed project and to any state agency which exercises resource management responsibility in the project area. The local public agency and state agency shall have 90 days to review and comment on the proposed coastal resource enhancement project. If, during that period that local public agency, a nonprofit organization, or the state agency agrees to carry out the project within the guidelines established in the resource enhancement plan, the conservancy may authorize the local public agency, a nonprofit organization, or the state agency to carry out the project, which shall then be subject to all provisions of this division.
