(1)(a) It is the intent of the legislature for the state to pay its fair share of the cost to implement the integrated plan. At least one-half of the total costs to finance the implementation of the integrated plan must be funded through federal, private, and other nonstate sources, including a significant contribution of funding from local project beneficiaries. This section applies to the total costs of the integrated plan and not to individual projects within the plan.
(b) The state's continuing support for the integrated plan shall be formally reevaluated independently by the governor and the legislature if, after December 31, 2021, and periodically thereafter, the actual funding provided through nonstate sources is less than one-half of all costs and if funding from local project beneficiaries does not comprise a significant portion of the nonstate sources.
(2) The department shall deliver, consistent with the intent of this section, a cost estimate and financing plan that addresses the total estimated cost to implement the integrated plan and analyzes various financing options. The cost estimate and financing plan must include a description of state expenditures as of September 28, 2013, incurred implementing the integrated plan and proposed state expenditures in the 2015-2017 biennium and beyond with proposed financing sources for each project.
(3) In addition, the office of the state treasurer shall prepare supplementary chapters to the cost estimate and financing plan for the department that:
(a) Identifies and evaluates potential new state financing sources to pay for the state's contribution towards the overall costs of the Yakima integrated plan's implementation;
(b) Identifies and evaluates potential new local financing sources to pay for a significant local contribution towards the overall costs of the Yakima integrated plan's implementation;
(c) Considers the viability, and evaluates the advantages and disadvantages of various financing mechanisms such as revenue bonds, general obligation bonds, and other financing models;
(d) Identifies past, current, and anticipated future costs that will be, or are anticipated to be, paid by nonstate sources such as federal sources, private sources, and local sources; and
(e) Considers how cost overruns of projects associated with the integrated plan could affect long-term financing of the overall integrated plan and provides options for how cost overruns can be addressed.
(4) The department may, in the sole discretion of the department, contract with state universities or private consultants for any part of the cost estimate and financing plan required under this section.
(5) The initial cost estimate and financing plan required by this section must be provided to the governor and the legislature, consistent with RCW 43.01.036
, by no later than December 15, 2014, for consideration in preparing the 2015-2017 biennial budget and future budgets. The cost estimate and financing plan must be updated by September 1st of each successive even-numbered year.
