Background

About the Tillamook Neighborhood Greenway

Portland’s neighborhood greenways are residential streets designed to prioritize bicycling and enhance conditions for walking. In Portland, there are currently more than 90 miles of neighborhood greenways, which were developed in three distinct phases since the first project on SE Salmon and Taylor streets more than 30 years ago. Learn more about Neighborhood Greenways.

Neighborhood greenways are a key component of Portland’s transportation system, and the City is committed to operating them as such.

About the Neighborhood Greenway Assessment Report and Guidelines

Portland’s 2015 Neighborhood Greenway Assessment Report recommended a series of performance guidelines for neighborhood greenways that are based on national and local guidance. Download the Neighborhood Greenway Assessment Report.

The report recommends the following performance guidelines for neighborhood greenways:

  • Vehicle speeds of 20 mph, measured as 85th percentile speed, which means that 85 percent of vehicles drive at or below this speed;
  • Automobile volume target of 1,000 Average Daily Traffic (ADT), with 1,500 ADT acceptable and 2,000 ADT maximum; and
  • Bicycle and pedestrian crossing opportunities, measured as a minimum of 50 crossing opportunities per hour, with 100 crossing opportunities per hour the preferred level of service.

Current Issues on the Tillamook Neighborhood Greenway

Vehicle Speeds

Problem: Sections of Tillamook see 85th percentile speeds of 23-25 mph. Some sections see 85th percentile speeds of 26-28 mph. 
Solution: Speed bumps at specific locations on the neighborhood greenway. Speed bumps are PBOT’s most effective tool to slow speeding auto traffic.

Intersection Control

Problem: Local and national guidelines recommend limiting the number of stop signs along a neighborhood greenway route in order to decrease travel time for bicyclists.
Solution: Convert stop signs on Tillamook to stop signs at the minor intersections, allowing people on bikes to flow continuously through the greenway.

Crossing Safety

Problem: Some busy intersection crossings are stressful for people walking and biking.
Solution: Improved crossing visibility with tools like bike boxes, marked crossings, and new signage.
