SW 19th Residential Street and Stormwater Project

Updated: January 3rd, 2018

Graphic: This project will improve water quality in Tryon CreekThe Portland bureaus of Environmental Services and Transportation have completed design of the Residential Street and Stormwater Improvement Project for SW 19th Avenue between SW Taylors Ferry Road and SW Marigold Street. This project will pave a dirt and gravel street, enhance an important pedestrian route, and improve water quality in Tryon Creek.

Project MapSchedule

The paving is expected to be complete early January. Following paving there will be additional road shoulder and grading work and topsoil and seed will be added to disturbed areas. The rain garden is complete and it will be planted this winter by Environmental Services watershed revegetation crews.

Please note that SW 19th will remain closed until construction is complete. Construction is expected to be complete January 2018.  

Transportation Improvements

SW 19th Avenue is an unimproved street covered with a mix of gravel, dirt and pavement. It is also an important pedestrian route, a designated Safe Route to School for Capitol Hill Elementary, and part of the regional Metro Hillsdale to Lake Oswego Trail and SW Urban Trail #6.

Using new street standards for improving dirt and gravel streets, the Portland Bureau of Transportation will pave SW 19th Avenue from SW Marigold Street to south of SW Orchid Street. 

Residential streets with lower traffic volumes can occupy a smaller portion of the public right-of-way and have a smaller footprint, less impervious surface and fewer impacts to streams and other natural features.

The southern portion of SW 19th near Taylors Ferry will remain closed. This portion of SW 19th Avenue was closed permanently to through traffic in 2002 because of safety concerns.

Environmental Improvements

Tryon Creek, where endangered steelhead trout and Chinook and coho salmon live, is just downhill of SW 19th Avenue. Rain can wash sediment and other pollutants off dirt and gravel streets and into streams.

To improve water quality in Tryon Creek, Environmental Services will construct a rain garden near SW Taylors Ferry Road at SW 19th Avenue. The city will install storm drains that will direct stormwater from the paved street surface to the stormwater facility.

Construction Phases

The project will be constructed in phases:

  • Install pipes and storm drains
  • Terrace and construct the stormwater facility
  • Remove the current street surface
  • Grade the street
  • Apply the new street surface
