(c) (1) The City of Santa Cruz, in conjunction with the Department of the Army, shall carry out the project referred to in subdivision (a) and may make modifications and amendments to the plans as may be necessary to carry out the plans for the purposes of Chapter 1 (commencing with Section 12750) and this chapter.

(2) Notwithstanding Section 12639, if there are any major modifications or amendments to the plans that result in a substantial increase in the costs to the state for any estimated cost for the project, no money shall be reallocated by the state in aid of that portion of the project until the revised plans have been reviewed and approved by the department. The department shall approve the revised plans if the department determines that the benefits of the proposed works of improvement for the revised project will exceed the cost thereof and that the revised project appears to be the most economical project plan, considering construction costs, land costs, easements and rights-of-way costs, and operation and maintenance costs.

(d) State funding for the project is contingent on the provision of funds for that purpose in either the annual Budget Act or a general obligation bond act. Reimbursement of the state share of the nonfederal costs of the project shall be for those project costs incurred on or after October 12, 1996, the date on which the project was authorized by Congress, as set forth in Section 101(a)(5) of the Water Resources Development Act of 1996 Public Law 104-303).
