(1) The CRAB/county contract shall include, but not be limited to, the following provisions:

(a) The contract shall be valid and binding, and the county shall be entitled to receive RATA funding in accordance with the vouchering/payment process as described in chapter 136-180 WAC, only if the contract is properly signed and returned to the county road administration board within forty-five calendar days of its mailing by the county road administration board.

(b) The county certifies that it is in compliance with the provisions of chapter 136-150 WAC.

(c) The project will be constructed in accordance with the scope, design and project limits as described in the final prospectus and in accordance with the plans and specifications approved by the county engineer, and, if applicable, the phased construction plan submitted by the county engineer to the county road administration board.

(d) The county will notify the county road administration board:

(i) If a single construction contract is intended to fully complete the project, at the time of project advertisement, construction contract, and when the project has been completed. Should the small works roster process be utilized, then the initial notice must occur prior to initiating the contractor selection process.

(ii) If county forces are utilized to fully complete the project, at the time of project notice, as required in RCW 36.77.070, commencement of construction activities, and when the project has been completed.

(iii) If the project applies a phased construction methodology, at those times described in a phased construction plan, consistent with subsection (2) of this section.

(e) The county road administration board will reimburse counties on the basis of monthly progress payment vouchers received and approved on individual projects in the order in which they are received in the county road administration board office, subject to the availability of RATA funds apportioned to the region; or subject to a minimum regional balance determined by the CRABoard for the purposes of cash flow; provided however, that if insufficient RATA funds are available or the legislature fails to appropriate sufficient RATA funds, payment of vouchers may be delayed or denied. Counties are ineligible to receive RATA funded construction cost reimbursements prior to satisfaction of the initial project notice requirement described in subsection (1)(d) of this section.

(f) The county will reimburse the RATA in the event a project postaudit reveals ineligible expenditures of RATA funds.

(g) The county may be required to reimburse the RATA in the event of early termination in accordance with the provisions of chapter 136-167 WAC.

(h) The county agrees to amend the contract in cases where:

(i) Additional RATA funds have been requested and approved under chapter 136-165 WAC;

(ii) Other relief from the original scope, design or project limits has been approved by the county road administration board under chapter 136-165 WAC; or

(iii) A project has been terminated without full RATA reimbursement under WAC 136-167-030(2).

(i) The county agrees to provide periodic project development progress reports as requested by the county road administration board.

(2) Counties may implement a phased construction methodology in the completion of RATA funded projects. A phased construction methodology is described as the process to implement multiple construction contracts through competitive bid and award, contracts awarded through exercise of the small works roster process, or construction by county forces, or a combination of two or more of these three methods, in order to complete a single RATA funded project. If a county elects to use phased construction methodology, construction of at least one of the project phases must commence by the lapsing date and all remaining phases must commence within two years of commencement of the first phase. In the event the county fails to meet either of these timelines, repayment of expended RATA funds for all phases of the project will be required unless waived by the county road administration board in keeping with the provisions of this section.

(a) In order to be considered phased construction, each phase must:

(i) Be distinct, independent, and nonoverlapping construction activities as to location and type of work;

(ii) Result in separate function and utility;

(iii) Be part of related and sequential construction activities that lead to overall project completion;

(iv) Separately and collectively comply with state laws as to procurement of contract work and use of county forces; and

(v) Not be implemented in a way that would otherwise be considered a split project, as described in WAC 136-170-060, without first obtaining approval as a split project.

(b) In order to satisfy notification requirement of subsection (1)(d) of this section, a phased construction plan must be developed and submitted to the county road administration board at least fifteen calendar days prior to contract bid advertisement, beginning the selection process for a contractor through a small works roster process, or commencement of construction by county forces, whichever occurs first. The phased construction plan must:

(i) Include a description of each construction phase, the contracting method to be employed or that county forces will be used;

(ii) Include an estimated cost and begin and end dates for each construction phase; and

(iii) Describe the relationship between construction phases and ultimate completion of the overall project.
