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.
