About this file
This is a landscape architecture bid set document prepared by Johnston Architects and Site Workshop for the Pierce County Library System's Sumner Library construction project located at 15126 Main Street East, Sumner, Washington. The landscape design encompasses site preparation and development of a 73,573 square-foot parcel including hardscape, softscape, irrigation, and site furnishings for the new 17,133 square-foot public library building. The scope includes removal of preload surcharge, site development conforming to City of Sumner zoning regulations and East Main Street design guidelines, construction of parking areas on the south portion of the site, and utility extensions. Key landscape components comprise CIP concrete paving with various finishes (broom finish, surface retarder, and stamped brick patterns), crushed rock paths and maintenance strips, specialty paving inlays (base bid dark exposed aggregate with optional stainless steel alternate), synthetic turf safety surfacing, tactile warning pavers, perimeter and construction drainage, landscape boulders (11 pieces ranging from 24" x 30" x 36" to 36" x 48" x 48"), retaining walls with sacked finish, fencing and gates, and site furnishings including bike racks, benches, picnic tables, musical features, and play equipment with an additive alternate for a Song Bird Play Element.
The design documents include detailed layout plans with precise dimensional specifications, site details with construction joint and paving inlay configurations, irrigation system design with master valve and quick coupler placement, soil specifications requiring imported topsoil at 12 inches depth with bark mulch and 6 inches depth with coarse sand mulch in planting areas, and comprehensive planting plans with native species identified by code. The bid set drawings (sheets L110 through L520) were issued in permit set form on June 16, 2023, with subsequent permit corrections on November 20, 2025, and revisions on October 12, 2025, February 25, 2026, and March 25, 2026. All landscape materials and installation methods are subject to manufacturer specifications and recommendations, with shop drawings required for specialty components including stainless steel fabrications, timber fence, and site signage. CAD files for layout of specialty paving inlay and play equipment placement will be provided to the contractor, with the landscape architect responsible for field direction of boulder orientation and final element positioning.
