Issaquah High School

AHBL is delivering civil engineering, landscape architecture, land use planning, and land surveying services for a new Issaquah School District high school designed for 1,800 students in grades 9–12. The 240,000 SF, three-story facility will include core learning spaces, science labs, athletic facilities, administrative areas, and community amenities such as a library, gym, commons, and performing arts center. The project also features an all-weather turf athletic field and is being executed as a Progressive Design-Build collaboration with Skanska and Bassetti Architects. 

AHBL’s team managed rezoning and master site planning for the 40-acre campus, which will include the high school, sports facilities, and an elementary school, along with road improvements in Sammamish. They addressed stakeholder concerns from a nearby retirement community and designed tree protection, planting and irrigation systems, turf fields, competition track, fencing, and entry plazas. Additionally, AHBL conducted SEPA environmental review, preparing technical studies on wetlands, traffic, noise, lighting, and stormwater impacts to Laughing Jacobs Creek. They supported the district’s Lead Agency role by issuing the SEPA checklist, MDNS, and coordinating filings with state and tribal agencies.
