Bellevue Botanical Gardens
BELLEVUE, WA–This new concrete skate park replicates some of the world’s favorite street skate spots. Instead of half pipes or bowls, it has ledges, banks, stairs, rails, benches, barriers and a pole jam. The drainage design prevents standing water, while minimizing impacts to the functionality of the park and providing a safer environment for the skaters. Civil design work included drainage analysis, detention design, temporary erosion and sediment control (TESC) plans, and construction services.
Evans Creek Preserve
SAMMAMISH, WA–The civil engineering improvements for Phase I of the Evans Creek Preserve include a new parking lot, a 2.6 mile trail and boardwalk system, pedestrian bridges, restrooms and wetland enhancements. The site’s topography ranges from nearly flat meadows to steep slopes that contain a variety of habitats, including wetlands, riparian corridors, and forested upland. This environmental education destination was constructed using Washington Trails Association volunteer labor and a publicly bid contractor.
Highland Skate Park

Instead of half pipes or bowls, it has ledges, banks, stairs, rails, benches, barriers and a pole jam.

Civil design work included drainage analysis, detention design, temporary erosion and sediment control (TESC) plans, and construction services.
Meridian Park Playfield Improvements
SHORELINE, WA–A new complex of three new fields — baseball, softball and playfield – will be the new home fields for the Shorewood High School baseball and softball teams. In addition to the new fields, site design created new parking for 30 vehicles, a quarter mile walking path, a gated, drive-thru bus holding area and various pathway connections to the adjacent school and community areas.
Since the City of Shoreline did not have a policy for mitigating runoff from synthetic turf, facilitation of drainage discussion between City staff, DOE, and WWHM model developers, helped the City develop a drainage design approach for this project and future sports field projects.
Mountaineers Clubhouse and Climbing Plaza
SEATTLE, WA–Along with the remodel of Building 67 as the Mountaineers’ new clubhouse, the site design replaced an existing garage with landscaped public open space, pathways, a rock amphitheater and an outdoor climbing wall. The open space south of the clubhouse is flanked by manmade steep slopes on the west and south sides of the climbing plaza. Site design involved coordination with the geotechnical engineer to establish design criteria for the stabilization of the designated Environmentally Critical Area steep slopes around the plaza, and the design of grading, paving, drainage, utility connections and temporary erosion control.
Norpoint Park
TACOMA, WA–Norpoint Park was transformed into the leading city park after numerous improvements that include a water “spray ground”, zip line, and improved skate park. This first phase of the park’s renovation involved site improvements for all play areas, the parking and vehicular drop off area, pedestrian plaza and walkways. Sustainable design elements integrated into the park include pervious pavement, eco-turf, a green roof on the restroom facilities and rain gardens for water quality and flow control.
Seahurst Environmental Science Center
BURIEN, WA–Creating a new environmental science center by renovating an old caretaker’s cottage and introducingsustainable design practices promotes the mission of the center – environmental stewardship.
Two rain gardens provide stormwater infiltration from roof runoff, aesthetic and educational features, and offer opportunities for visitors to learn about low impact development.
LPD prepared construction documents for the rain gardens, grading and erosion and sedimentation control for the project. Other site design elements included modifications to an existing gravel access drive, construction of a pervious concrete driveway in front of the building, and re-routing of the existing dirt hiking trail.
