Project Details:

Centennial Trail Phase 2, Arlington, WA (2009 to 2012) Owner: Snohomish County Department of Parks & Recreation Contract Amount: $4.9 Million This project involves building approximately 8 miles of paved pedestrian and equestrian trail. The project follows an old railroad grade paralleling Highway 9. Construction began in the fall of 2009 with clearing and grading. As part of the project, a new bridge is being built and two existing trestles are being retrofitted for pedestrian use. Other project requirements include installing storm drainage, reinforced slopes, and wetland enhancements. A bank failure along the Pilchuck Creek, and undermining of an existing pier have extended the project 2 work seasons. Additional project requirements to repair both issues have involved bypassing a significant creek, installing 2 timber crib walls, bracing and excavating under an existing pier, installing new 30” diameter shafts with concrete foundation around the existing pier, and significant slope / revetment work to re-stabilize the banks. The project is currently scheduled for completion in 2012. Centennial Trail Phase 1 Stage 3, Arlington, WA (2011) Owner: Snohomish County Department of Parks & Recreation Contract Amount: $1.2 Million This project is an extension to the above project that was awarded under separate contract. Approximately 1.1 miles of additional paved pedestrian trail was constructed through primarily the center of wetlands. Construction began in the summer of 2011, and was completed in the fall. Project requirements to complete the trail included clearing and grading, drainage, stream diversion with box culvert installation in halves to accommodate vehicular traffic remaining open that crossed the trail, and wetland enhancements. Centennial Trail Extension Project, Snohomish, WA (2011 to 2012) Owner: City of Snohomish Contract Amount: $800,000 This project is another extension to the above 2 same pedestrian paved trails that was awarded under separate contract.
