The City of Portland is designing stormwater management and transportation improvements on SW 19th Avenue. SW 19th Avenue is an unimproved street covered with a mix of gravel, dirt and pavement. It is 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 community SW Trail #6.
Rain can wash sediment and other pollutants off gravel and dirt streets and into streams. Tryon Creek, where endangered steelhead trout and Chinook and coho salmon live, is just downhill of SW 19th Avenue.
The Portland Bureau of Transportation is designing a paved street on two blocks of SW 19th from SW Orchid to SW Marigold using new street standards developed in the bureau’s Residential Street Program and the Tryon-Stephens Headwaters Neighborhood Street Plan. Residential streets with lower traffic volumes can occupy a smaller portion of the right-of-way and have a smaller footprint, less impervious surface and fewer impacts to streams and other natural features.
To improve water quality in Tryon Creek, Environmental Services is designing vegetated stormwater facilities on SW 19th Avenue including a large facility between SW Taylors Ferry Road and SW Orchid Street, a site the city closed to through traffic in 2002 because of safety concerns.
The city is designing the project and will begin construction in spring 2017.
