Bow Lake Elementary School

Highline Public Schools, SeaTac, WA

AHBL provided civil engineering for the new replacement Bow Lake Elementary School. The 75,000 sf school replaced the old Bow Lake Elementary and is located on the school’s existing site in SeaTac.The project included the demolition of the existing buildings, parking, sidewalks, and site utilities. New construction included a new school building, asphalt parking areas, an onsite bus loading/unloading area, sidewalks, landscape plaza, new site utilities, and frontage improvements to meet the City of SeaTac standards.

The civil engineering scope of work also included the design of a new stormwater drainage system that included bioswales and rain gardens for on-site water quality treatment. One large rain garden is located near the front corner of the school and three smaller, grass-lined bioswales provide treatment for run-off in the parking lots.. AHBL coordinated with the landscape architect to include amended soils and native plantings in the rain garden to promote water quality treatment.
