Update to the Neighborhood – March 2013

Leslie Smith, Executive Director of the Alliance for Pioneer SquareTwo Things this Month

Changes to the Pioneer Square BIA

A goal critical to the future of the Alliance and the neighborhood… aligning the Pioneer Square BIA with the Historic District boundary was originally articulated in the Pioneer Square 2015 neighborhood plan. After many months of work the BIA Ratepayer Board and the Alliance for Pioneer Square are ready to make this happen. Comprehensive outreach for petition signing will begin in the next few weeks with a goal of having an expanded BIA in place in January of 2014.

Interested in learning the details and impact on your business? Interested in hosting a gathering for neighboring businesses or helping in other ways? Please contact leslie[at]

Business Improvement Areas (BIAs) are special assessment districts, or “self help mechanisms” whereby business owners choose to assess themselves to revitalize and enhance neighborhood business districts. The oldest BIA within the City of Seattle, the Pioneer Square BIA was formed as a local business community effort to remain competitive in the marketplace. The legal authority for the establishment and management of BIAs is set forth in the Revised Code of Washington (RCW) Chapter 35.87A and Seattle City Ordinance 111244.
