WA PRA/NPS-PWR-PRES-1(09), Washington State Parks, Pavement Preservation

Project Details: This project provides pavement preservation various roadways in Lake Roosevelt National Recreation Area, Mount Rainier National Park, North Cascades National Park, Olympic National Park and San Juan Island National Historic Park. These Parks are located in Washington State in the Clallam, Lewis, Lincoln, Pierce, San Juan, Skagit and Whatcom. These Parks extend from the Olympic Peninsula, through the Cascade Mountain Range to the Columbia River Valley of Eastern Washington.



The main preservation treatments being use are chip seals, a double chip seal and modified slurry seals. Other construction applications used on a lesser scale are pavement patching, crack sealing and pavement markings.



The work at Lake Roosevelt consists of approximately 87,000 square yards of modified slurry seal. This work is confined to the areas at the southern end of the Lake at Spring Canyon, Keller Ferry, Hawk Creek and other nearby areas.



The Mount Rainier work includes 470,000 square yards of chip seals and 80,000 square yards of modified slurry seals. The major areas or work are Sunrise, Longmire, Cougar Rock and Tahoma Woods.



The work at North Cascades consists of 126,000 square yards of modified slurry seal. The only areas of the Park not being treated are Stehekin Valley and Fields Point. All areas near Washington State Route 20 are included in this project.



The work at Olympic National Park includes 210,000 square yards of chip seal. This work is confined to 12.3 miles of US-101, also knows as Lake Crescent Highway. Many other routes within the Park will also receive pavement markings.



Work as San Juan Island National Historic Site consists of 90,000 square yards of chip sealing on existing paved surfaces. An additional 12,500 square yards of gravel roadway and parking will receive a new double chip seal.



This project uses a combination of Park Service Cyclic Maintenance funds and Federal Lands Highway Program funds. The estimated price is $3 to $7 million. Advertisement is expected in late June, 2009.
