This is a construction design document prepared by the Washington State Parks and Recreation Commission for the Anderson Lake State Park New Day Use Facilities and Trail Development project located at 1061 Anderson Lake Road, Chimacum, Washington 98325, in Jefferson County. The project encompasses comprehensive site improvements including paving the park's main entrance road with hot mixed asphalt (HMA), developing multi-use trails with both pedestrian and equestrian components, constructing approximately 380 linear feet of elevated boardwalk with concrete plank decking and steel beam support systems, establishing new day-use parking facilities with ADA-accessible spaces, installing signage and striping, removal of two existing vault restrooms, and construction of two new CXT modular restroom buildings. The design incorporates three distinct trail types: separated equestrian trails, separated pedestrian trails, and multi-use trails, with detailed specifications for trail widths ranging from 8 to 10 feet. The boardwalk section (stations 14+59 to 18+42) features W8X18 and W8X31 steel beams supported by 3.5-inch diameter galvanized steel pipe piles with concrete abutments and neoprene bearings, accommodating slopes up to 6.5 percent with 8-foot spacing between support lines. Site work includes stormwater management with silt fencing and vegetation buffers, tree removal and protection measures, and equipment access staging areas.

The design documents establish detailed specifications for materials and construction standards conforming to AASHTO guidelines, AISC structural steel standards, and WSDOT 2023 Standard Specifications. All structural steel components are hot-dipped galvanized per ASTM A-123 standards, concrete is specified at 6000 PSI minimum compressive strength at 28 days with prestressed deck panels utilizing ASTM A416 Grade 270 strands, and lumber components are pressure-treated Douglas fir or cedar. The project incorporates comprehensive details for concrete plank layouts with 47 special concrete panel configurations, railing systems using cedar hand rails and galvanized hog wire panels, and temporary construction specifications including equipment access mats and turnaround areas. Special inspection requirements are mandated for all concrete work, field welding, and high-strength bolting. Construction cost details and funding sources are not specified in the design documents, though the project is managed by the Washington State Parks and Recreation Commission with regional oversight from the Port Angeles area office, with design completion dated March 17, 2026.
