The 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, improve an important pedestrian route, and improve water quality in Tryon Creek.
Currently our contractor is preparing plans for construction of the project. Work should begin in the next few weeks.
Construction is anticipated to take approximately three months to complete, once the project begins.
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.
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 vegetated stormwater facility 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.
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
