Future Context: UW Master PlanWest CampusThe West Campus is the most urban of the
four campus sectors and accommodates a
wide range of uses including student housing,
academic, research, and cultural programs.
Given its regional transportation access
from I-5, regional transit services, retail,
research in numerous fields, as well as cafes,
industry partners and a significant supply
of UW-operated student housing, the West
Campus is uniquely positioned to develop as
an “innovation district” within the broader
Seattle region (see page 38 for more detail
on academic and research partnerships). The
long-term vision for the West Campus:
Significant Pedestrian Path
Significant Open Space
Active Ground Floor
Existing Building
Potential Building
Gateway
Connects the campus and University District to their waterfronts.
Provides flexible building footprints and massing to accommodate a range of functions, including academic and research partnerships.
Extends and re-establishes the street grid, and improves connections with the adjacent University District.
Increases development capacity and balances dense development with access to open space.
Reinforces east-west connections with South Campus.
Creates pedestrian-scaled development parcels and activates street life with ground floor active destinations.
Enhances connections with Central Campus.
