Wat. Code, § 12670.16

(a) Notwithstanding any other provision of law, the Sacramento Area Flood Control Agency’s share of the nonfederal capital costs of the projects for flood control authorized in Section 12670.14 shall be calculated in accordance with Section 12585.5, and the agency shall be reimbursed pursuant to Section 12585.5 for any costs of project features that the agency advances on behalf of the department or Reclamation Board if either of the following requirements is met:

(1) The advances are made in response to a federal request for payment of the nonfederal share of the cost of the project.

(2) If the advances are made for project features that have not yet been authorized by Congress, the Reclamation Board has received a written determination by the federal government that the project features will likely be authorized by Congress and, if so authorized, the advances will be eligible for credit toward the nonfederal share of the cost of these features.

(b) Prior to any reimbursement pursuant to subdivision (a), the agency shall execute an agreement with the department under which it agrees to indemnify and hold the state harmless from damages due to the construction, operation, or maintenance of those projects and agrees to operate, maintain, repair, replace, and rehabilitate those projects, or provide the agreement of its appropriate member agency to do so.
