How You Benefit
Cross GlyphImproves Safety
The chip sealing process increases traction and skid resistance. It fills cracks and raveled surfaces, providing a smoother, safer ride. It also provides an anti-glare surface when wet and increases reflectivity at night.  Fresh striping and new signage also improves safety.
Leaf Glyph Protects Environment
An Environmental Review Summary was signed August 23rd, 2006 under terms of the National Environmental Policy Act, permitting the project.
The followings are the permits and/or project documentation required:

BA - Biological Assessment.
NEPA (CE) - National Environmental Policy Act of 1969.
SEPA (CE) - State Environmental Policy Act of 1971.
Temporary Erosion Control Plan.
Section 106 - Tribal Consultation
Dollar Sign Glyph Economic Incentive
This project extends pavement life on 141 miles of state highway by providing a waterproof layer protecting the underlying pavement structure.

Partnerships & Cooperation
A project to construct new channelization at the junction of Thacker Road and SR 26, near Othello in Adams County was included in the chip seal contract to reduce costs and deliver it a year early.
