The new Stillaguamish Tribe’s Natural Resources Department building has opened in Arlington, Washington. Per the Seattle DJC, This 13,000 s.f. office and lab building was designed by Anacortes-based Brooks Middleton Architect and “… was built to honor traditional tribal structures and make efficient use of natural resources. ”
Herrera Associate Engineer Chris Webb was Civil Engineer on the project prior to joining Herrera, and worked closely with the team on realizing a number of sustainable site features. This was a complex site development project with steep slopes, wetlands, flood plain/ESA issues, and a restrictive layer near the surface overlain by granular soils as complexities. The approach included LID based site design, incorporating a number of sustainable features, including a bioretention cell in front of the building (seen in the image above). Chris was also responsible for the on-site wastewater system which was implemented subsurface drip irrigation to preserve trees.
