Georgetown Arterial Paving Project

February 28, 2017

Project Overview

S Michigan St, along with several blocks of Corson Ave S and a block of S Bailey St are all heavily traveled arterials in the Georgetown community that are showing the wear and tear of use.  The potholes and cracks in the pavement are such that we plan to repave these streets in 2017:

  • S Michigan St from 4th Ave S to Corson Ave S
  • Corson Ave S from S Michigan St to S Orcas St
  • S Bailey St from Corson Ave S to Carleton Ave S.

While the project is still in the design phase, SDOT expects construction to begin sometime this spring, and take about three to four months to complete. 

Before repaving the street, a 2-inch deep layer of the existing asphalt will be ground off.  Crews will then evaluate the underlying road base for any additional needed repairs to make sure the road can better withstand the weight of heavy trucks that regularly traverse these streets.  Once these base repairs have been completed, a new 2-inch layer of asphalt will be applied. 

The project will also:

  • Replace curb ramps in select locations to bring them into compliance with the federal Americans with Disabilities Act (ADA).
  • Install several new drainage catch basins where water currently ponds in the road.
  • Restripe all existing traffic lane markings and crosswalks.

Prior to the repaving, we'll also upgrade traffic signals at:

  • E Marginal Way & S Michigan St
  • 4th Ave S & S Michigan St
  • 5th Place S & S Michigan St
  • Corson Ave S & S Michigan St
  • S Bailey St & Carleton Ave S

These upgraded signals are part of SDOT's ongoing efforts to incorporate advancing technologies (known as Intelligent Transportation Systems) throughout the City, and will also include the addition of new traffic cameras at 6th Ave S & S Michigan St and at Carleton Ave S & S Bailey St.

These cameras are in addition to 3 already operational along S Michigan St.  The cameras provide real-time information about traffic conditions, and are publicly available online, enabling you to assess road conditions before leaving home or work.  The same views provide critical information to SDOT itself to assess road conditions at any given time.


Environmental Review

1/12/2017 After a careful environmental review, the Seattle Department of Transportation (SDOT) has determined that the paving and other work associated with the project will not have a probable significant adverse impact on the environment. SDOT is required to consider the environmental consequences of proposed projects under the Washington State Environmental Policy Act (SEPA). SDOT issued a SEPA Determination of Non-Significance (DNS), linked below, on Thursday, January 12, 2017. The supporting SEPA checklist, linked below, includes a summary of the project's impacts on water quality, air quality, plants, animals, hazardous materials, noise, land use, light, recreation, cultural resources, parking, and other disciplines. The public comment period for the DNS is open until January 26, 2017.  The DNS appeal period closes on February 2, 2017.

Construction Impacts

We don't expect that construction will require the full closure of S Michigan St, Corson Ave S, or S Bailey St at any point (although some side streets may be closed for short periods).  However, traffic will likely be reduced to a single travel lane in each direction (outside of the morning and afternoon commute peaks), which is likely to cause congestion.  Some weekend and/or night work is also possible. 

Sidewalks will remain open during construction, although corners will be closed when and where new curb ramps are being installed.

Current conditions


We don't have specific details on construction sequencing or timing yet, but will have more information after a contractor is hired.  We expect more details in early 2017, at which point this website will be updated to include this information. 

Project Funding

Project Budget:  $3.1 million (including design & construction)
