Delridge-Highland Park Neighborhood Greenway

Creating a network of family-friendly residential streets

Last updated: August 26, 2015

Project Update

What's Happening?

Construction on the Delridge-Highland Park Neighborhood Greenway begins on August 26.

August 26 – 28: Construction at SW Myrtle Street between 21st Avenue SW and 17th Avenue SW

From August 26 through August 28, between 7 AM and 5 PM, SW Myrtle Street between 21st Avenue SW and 17th Ave SW will be closed to through traffic. There will be no parking on either side of the street during this time. Local access will be maintained.

August 26: SDOT's contractor, CA Carey, will remove the top layer of asphalt and prepare the road surface for repaving. Note: this work will be noisy.

August 27: The contractor will repave the street. To allow crews to pave the roadway, driveway access will be temporarily restricted on SW Myrtle Street between 17th Avenue SW and 21st Avenue SW. Restrictions will be in place between 7 AM and 5 PM. We ask residents to move vehicles to a nearby street if you intend to use them during these times.

Beginning September 1: Construction on SW Andover Street between 22nd Avenue S and 21st Avenue S

The contractor will widen the sidewalk along SW Andover Street between 22nd Avenue S and 21st Avenue S. Curb ramps will be installed at SW Andover Street and 22nd Avenue S. Curb ramps and new crossing improvements will be installed at SW Andover Street and 21st Avenue S. This work will last approximately 16 days.
 
As construction progresses throughout the corridor, you can expect the following:

  • Temporary on-street parking restrictions
  • Short-term single lane closures, where needed
  • Pedestrian and bicyclist detours
  • Noise, dust, and vibration typical of construction
  • Weekday work hours form 7 AM to 5 PM

Seattle is building a network of neighborhood greenways. Neighborhood greenways are safer, calmer residential streets for you, your family, neighbors and customers. On streets with low car volumes and speeds, a greenway can:

  • Improve safety
  • Help people cross busy streets
  • Discourage cut-thru traffic
  • Protect the residential character of our neighborhoods
  • Keep vehicle speeds low
  • Get people to where they want to go (e.g., parks, schools, shops and restaurants)

Neighborhood greenways are not car-free zones; they do not add bike lanes; and there are minimal, if any, on-street parking impacts. Learn more about greenways here.

 

Project Description

The greenway will run north-south, connecting White Center to the West Seattle Bridge trail. The greenway route will run generally along 17th Avenue SW in the south and 21st Avenue SW in the north. For a full description of the improvements we designed for this greenway and the route, please see the attached map. Some of the changes will include:

  • Crossing improvements at arterial intersections including striped crosswalks, curb extensions and flashing beacons
  • Repaving SW Myrtle Street between 17th and 21st Avenue SW
  • Speed humps and all-way stops where need, generally about one per block
  • Way-finding signage and pavement markings throughout
  • Spot pavement repairs to improve roadway user safety

The greenway route was selected based on various factors, including evaluating streets for low car volumes, speeds and collisions, road grade (or steepness), and input we heard from the community.

SDOT is working with Seattle Public Utilities (SPU) to design curb extensions with natural drainage systems along 17th Avenue SW, between SW Henderson Street and SW Kenyon Street. To learn more about SPU's Delridge Natural Drainage Systems project, check out their Web page or contact Don Anderson, SPU Project Manager, at donald.anderson@seattle.gov or call (206) 233-1086.

Public Outreach

In 2013, the City conducted a survey and held two public meetings to identify the most promising route and safety improvements for a neighborhood greenway in the Delridge/Highland Park community. We received valuable feedback on traffic safety concerns, destinations where people want to walk and bike to, as well as known drainage and sewer backup problems. After analyzing data and reviewing public input, the most-promising greenway route was determined to be 17th Avenue SW from Roxbury to SW Kenyon or Holden Streets and 21st Avenue SW on the north end.

Project outreach has included:

  • Neighborhood survey responses (we received more than 280)
  • July 9, 2013 public meeting (where more than 80 people participated)
  • November 19, 2013 public meeting
  • Door-to-door flyering to affected properties
  • Meetings with community groups

Staff also walked and biked around your neighborhood to review different routes and observe locations and grades. Other information considered included traffic volume, speed, and collision data.

Project Funding

Project design of the neighborhood greenway is locally funded by the nine-year voter-approved Bridging the Gap Levy. This project is part of a $3.8 million budget to design and construct the 2015 Ballard and Delridge-Highland Park Greenways.

The natural drainage portion of the project is being funded by SPU.

Project Schedule

The project reached final design and construction will begin on August 24 and last for approximately four months.
