(1) Certification of county arterial mileage.

(a) Classification. The statute specifies that expenditure of CAPA funds is restricted to paved arterials in the unincorporated area of each county. Arterials are defined as being those county roads:

(i) In urban areas, classified within the federal functional classification system as arterials or collectors;

(ii) In rural areas, classified within the federal functional classification system as arterials, major collectors, or minor collectors.

(b) Paved roads are defined as those roads which, at the time of CAPA allocation determination, are hard-surfaced through the application of a bituminous surface treatment (BST), asphaltic concrete pavement (ACP), or portland cement concrete (PCC). Brick or block surfaces shall also be considered as paved.

(c) Source of information. The master county road log as maintained by the county road administration board in accordance with chapter 136-60 WAC shall be the source of official paved road mileage to be used for CAPA distribution.

(2) Establishment of allocation percentages. At its first regular meeting after July 1 of each year, the county road administration board shall establish the next calendar year's allocation percentages for the individual counties based on information contained in the most recently certified master county road log. Each county's allocation percentage shall be computed by the county road administration board as its percentage of paved arterial lane miles of the total statewide paved county arterial lane miles.

(3) Notice to counties. Upon their establishment, the county road administration board shall notify the county legislative authority and the county engineer of each county of the respective county's CAPA allocation percentage and the latest estimate of the amount of CAPA funds to be allocated during the next calendar year.

(4) Distribution to counties. Distribution of allocated CAPA funds shall be done monthly by the state treasurer. The state treasurer shall use the allocation percentages provided by the county road administration board as computed under the provisions of subsection (2) of this section.

(5) Eligibility. All arterial preservation work and related activities, and maintenance management done by each county shall be eligible for CAPA funding provided that:

(a) The county is determined to be in compliance with the pavement management system requirements as set forth in chapter 136-70 WAC; and

(b) The county engineer submits the annual county arterial preservation program (CAPP) to CRAB as required in WAC 136-300-060; and
