Validation requirements for control fields.

Each update of a road log segment that involves a change in a control field (including additions or deletions of road segments) will be validated by the county road administration board. Documentation necessary to support control field changes is as follows:
Function class - Notice of FHWA approval from WSDOT.
Pavement type - Statement signed by county engineer with list of pavement type changes.
Responsible agency - The responsible agency is the legislative authority of the appropriate governmental agency with the authority to make the decision required for the action, or the state or federal government person authorized to approve changes.
Addition of mileage - Official document signed by responsible agency authorizing and describing the circumstances of the addition. For example, additions can occur through county legislative approval of new plat, construction/reconstruction on new alignment, or a change in jurisdiction.
Deletion of mileage - Official document signed by responsible agency authorizing and describing the circumstances of the deletion. For example, deletions can occur through legislative approval of vacations or a change in jurisdiction.
Traffic volume - Statement signed by county engineer with list of segments affected by change in traffic volume above or below 5,000 average daily traffic (ADT). If the ADT is over 5,000, the county shall also submit the traffic counts used to determine the ADT.
Freight and goods – Statement signed by county engineer with list of segments above 4,000,000 tons of freight annually and the traffic counts used to determine the annual tons of freight exceed 4,000,000 tons.
All changes to a control field will be updated in the approved GIS data set layer with sufficient detail to identify the location of each change. This GIS layer will then be forwarded annually to WSDOT for the new federal requirements for Highway Performance Monitoring System (HPMS) and Model Inventory Roadway Elements: Fundamental data elements (MIRE FDE).
