1.1 WATERFRONT SEATTLE Over the past few years, the City of Seattle has been actively re-imagining the future of its Central Waterfront. The imminent replacement of the Elliott Bay Seawall and removal of the Alaskan Way Viaduct now present a tremendous opportunity to turn visions into reality and create a vibrant public realm that will reconnect the city and its people to their waterfront. With a new surface street, improved east-west connections and enhanced access to the waterfront, the vision for Seattle’s Central Waterfront will extend into the heart of the city and claim a new and authentic front porch on Elliott Bay. This Schematic Design document draws on the vision outlined for Waterfront Seattle in the July 2012 Planning and Design Document and specifically on the concepts described in Book 3: Concept Design, which focuses on the initial “core project” area of Waterfront Seattle. This is not a legal or binding document, but a summary of the Schematic Design work put forth during the Schematic Design phase of the Central Waterfront Project.

3. Reconnect the city to its waterfront. The waterfront should provide a front porch to the downtown neighborhoods and the city. It will build a network of public spaces that connect the waterfront to important destinations, nearby neighborhoods, the city and region. 4. Embrace and celebrate Seattle’s past, present and future. The waterfront is a lens through which to understand Seattle—from its natural history and early Native American settlements, to the rich variety of maritime, industrial, commercial and recreational activities today. The waterfront should tell these stories in ways that are authentic and bring them to life.

Programmed Recreation: The pool barge will bring a programmed recreation amenity to Seattle’s central waterfront, serving residents of downtown as well as visitors, complementing the passive recreation and programmed events associated with other waterfront elements. As a programmed recreation facility and a maritime vessel, the pool barge is shaped by a highly detailed level of regulatory and operations detail that will continue to guide design decisions.
