PROJECT DESCRIPTION Seattle's Central Waterfront is heralded as one of the most significant civic projects in the city's history. With imminent removal of the Alaskan Way Viaduct and current replacement of the aging Elliott Bay Seawall, Seattle has begun to envision and enact a great "waterfront for all." Removal of the viaduct and rerouting of Alaskan Way along the waterfront will create abundant new and qualitatively different public space, while the seawall replacement will provide for a more ecologically functional edge. However, while the team led by James Corner Field Operations has proposed and designed a new waterfront between Piers 48 and 62/63, less attention has been paid to the waterfront segment between Piers 62/63 and the Olympic Sculpture Park. With the reconfiguration of Alaskan Way, this northern segment offers rich opportunities for better public, pedestrian, bicycle and ecological space along a less-traveled roadway.

    BUSINESS IMPROVEMENT AtARE Work in SeattleAS A guide to the legislation and strategies for its use SEATTLE OFFICE OF ECONOMIC DEVELOPMENT’S ONLY IN SEATTLE INITIATIVE This publication is an outgrowth of the Business Improvement Area (BIA) Assistance Program. Part of the Seattle Office of Economic Development’s Only in Seattle Initiative, the BIA Assistance Program provides training and technical assistance to business districts throughout the city in forming, managing, and updating Business Improvement Areas. For more information about Only in Seattle or the BIA Assistance Program, contact the Office of Economic Development at [email protected] or 206.684.8090 or www.seattle.gov/economicdevelopment. Spring 2012 EXECUTIVE SUMMARY EXECUTIVE SUMMARY What are BIAs? BUSINESS IMPROVEMENT AREAS (BIAs) are funding mechanisms for business district revitalization and management. Specifically, the mechanism is an assessment collected from businesses and/or properties within defined boundaries. The funds collected are used to provide services for the mutual benefit of the businesses and properties being assessed. The concept of business district management funded through mandatory assessments has been around for many years, and gained wide popularity during the 1990s. Under one name or another, well over 1,000 such districts exist throughout the United States, with many more in Canada and throughout the world. BIAs include programs and services such as marketing, public area maintenance, security, parking, streetscape improvements, and professional management. Each BIA has a ratepayers advisory board made up of ratepayers within the BIA boundary. Creating a BIA In Seattle, BIAs are enacted by the City Council, using the authority of state law (RCW 35.87A) and the city charter.

Earthquake Hazards of the Pacific Northwest Coastal and Marine Regions Robert Kayen, Editor Seismic Stability of the Duwamish River Delta, Seattle, Washington By Robert E. Kayen and Walter A. Barnhardt The delta front of the Duwamish River valley near Elliott Bay and Harbor Island is founded on young Holocene deposits shaped by sea-level rise, episodic volcanism, and seismicity. These river-mouth deposits are highly susceptible to seismic soil liquefac- tion and are potentially prone to submarine landsliding and disintegrative flow failure.

INTRODUCTION Many important and long planned transportation and development projects are scheduled for con- struction in Downtown Seattle in the coming years. While these investments are essential to support economic development and job growth and to enhance Downtown’s stature as the region’s premier location to live, work, shop and play, in the short-term they present complicated challenges for con- venient and reliable access to and through Downtown. The Downtown Seattle Association (DSA) and its partners, Historic South Downtown (HSD) and the Seat- tle Department of Transportation (SDOT), seek to ensure that Downtown Seattle survives and prospers during the extraordinarily high level of construction activity that will occur in the coming years.

The study identified alternative governance structures that could help the Alaska Marine Highway System (AMHS) achieve financial sustainability. This statewide effort was managed by Southeast Conference and guided by a 12- member steering committee of stakeholders from across Alaska. Project tasks included a high-level examination of six basic ferry governance models to assess their suitability for Alaska’s unique geography, markets, and transportation needs. More detailed case studies were conducted with three ferry systems to identify ideas and lessons applicable to AMHS: British Columbia Ferry System, Steamship Authority (Massachusetts), and CalMac Ferries (Scotland). The study also included review of relevant AMHS reports and interviews with key AMHS contacts including senior management and union representatives. The project incorporated extensive public involvement including convening a Statewide Marine Transportation Summit, solicitation of feedback through the project website, outreach to municipal governments and trade organizations throughout Alaska, and a presentation and discussion at Southeast Conference Annual Meeting.

    HISTORY: PARK 11/6/76 When the Duwamish tribe inhabited the land between the Whulge (Puget Sound) and Hyas Chuck (Lake Washington), the hills along this part of the bay sloped steeply into the waters. The flat strip along the waterfront, from Yesler Way to Smith Cove is the result of fills. European explorers renamed many geographic features. In 1791 Captain Vancouver Puget Sound to honor Lt.

They had scarcely finished construction of four cabins when a passing brig stopped, looking for a cargo of timber piles which the settlers eagerly provided. But it was obvious that water off shore was for a harbor. So they changed the site of the settle- ment to the shore of Elliott Bay. In 1853 Henry Yesler arrived and the commercial development of the waterfront with the construction of a sawmill. At first, skid roads, wagons and boats were able to supply the demands of the vessels from San Francisco and other ports of call, but when coal was discovered in the 1860's a faster means of overland transport was needed - the railroad. Tracks were laid from the growing town to the south end of Lake Union and by 1374 went to Renton and the mines of New Castle.
