Construction Hub Coordination Program

Access Seattle Initiative
Construction Hub Coordination Program

June 11, 2015


Seattle is experiencing unprecedented growth and development, both in the downtown Center City area and surrounding neighborhoods. The City of Seattle recognizes that construction can create challenges. Access Seattle is an initiative focused on maintaining mobility in the city during peak construction periods, addressing the impacts in three ways:

  1. Business and community support;
  2. Traveler engagement; and
  3. Construction coordination

A critical element of the Access Seattle Initiative is the new Construction Hub Coordination Program. The hub team of project and on-site coordinators assess permitted construction holistically, across public and private lines, in areas with multiple simultaneous construction projects in close proximity—otherwise known as construction hubs. See below for more information on the current identified hubs-subject to change with the evolving construction landscape.


The job of the Construction Hub Coordination Program is to proactively address and respond to the cumulative mobility impacts in Construction Hubs through active management of construction-related issues. The objectives of the program are as follows:

  • Identify high development areas as Construction Hubs
  • Evaluate impacts for the duration of each project for all projects within these areas collectively, highlighting potential conflicts and cumulative mobility impacts
  • Provide guidance on ways to maintain mobility in these areas experiencing significant construction impacts
  • Establish reliable lines of two-way communications with key community and business representatives to address construction-related impacts and to flag policy-level issues
  • Respond and resolve construction-related impacts in “real-time”

The Access Seattle construction coordination effort comes at a time when downtown Seattle has more projects under construction, about to break ground or recently completed (the last 1.5 years) than it has in the seven years preceding January 2013, according to the Downtown Seattle Association Development Guide June 2014 Update. That update also found that in the last year the amount of office space under construction has nearly doubled, and there are more than three times the number of apartment units under construction compared to the last development cycle in 2007.


At present, seven Construction Hub areas are identified. These areas are shown on the Construction Hubs Boundaries Map below, and listed in the chart that follows.  

Please note: This map is currently being updated. The Capitol Hill Hub western boundary is I-5.


South Lake Union

Area bounded by Mercer St to the north, Dexter Ave N to the west, Denny Way to the south, and Eastlake Ave E to the east

Alaskan Way Viaduct South (Central Waterfront)

Area bounded by Bay St/Broad St to the north, S Holgate to the south, Elliott Bay to the west, Occidental Ave S/1st Ave to the east.

Alaskan Way Viaduct North

Area bounded by Aloha St the north, Bell St to the south, 5th Ave N/4th Ave N to the west, and Dexter Ave N/7th Ave to the east.

North Westlake

Area bounded by 9th Ave to the northeast, Bell St to the northwest, 5th Ave to the southwest, and Stewart St to the southeast.

Capitol Hill

Area bounded by E Harrison St to the north, I-5 to the west, E Madison St/E Spring St to the south, and 15th Ave to the east.


Area bounded by NW 65th St to the north, 24th Ave NW to the west, Shilshole Ave NW to the south, and 8th Ave NW to the east.

West Seattle

Area bounded by Oregon St to the north, California Ave SW to the west, SW Dawson St to the south, and 37th Ave SW to the east.


Given the recent increase in development, there are now multiple private and public construction projects simultaneously underway in close proximity in many neighborhoods across the City of Seattle. These areas have been identified and named Construction Hubs.

Construction Hubs often happen within urban village boundaries or areas that were recently re-zoned, and where there is also significant public investment (e.g. First Hill Street Car, Denny Substation, Mercer Corridor, etc.).

If projects in these areas are not coordinated across departments and between the public and private sector, they can cause significant cumulative mobility impacts to businesses, residents, pedestrians and cyclists.

The Construction Hub Coordination Program is a part of Access Seattle, a Seattle Department of Transportation initiative to keep businesses thriving, travelers moving, and construction coordinated during peak building periods. In mid-2013, SDOT Street Use refocused the work programs of two existing staff to create the backbone of a Construction Hub Coordination Program, in support of Access Seattle. Three additional team members were hired in 2014. To help meet the critical need for construction coordination, another staff member will be hired in 2015, bringing the number of staff to five. Joining the team is also a business liaison, provided by the Office for Economic Development.
