Provides that, every ten years, beginning December 1, 2006, the secretary shall present to the legislative transportation committees of the house of representatives and senate a proposed reorganization of the department's regions. If appropriate, the reorganization proposal shall recommend new regional boundaries, determined geographically, accounting for projects and other workload funded in the next sixteen years. Where appropriate, projects along the same corridor shall be kept within a single region.

Declares an intent that this act will result in periodic reviews of the department of transportation's regional boundaries. The department should review resources and outputs (such as projects and maintenance work) within each region and determine if changes to regional boundaries would benefit the department and, therefore, the public. As growth and other economic changes occur in Washington state, it may be appropriate to change the size and/or number of departmental regions.
