City Bureaus Devise Plan for Street Improvements in Southwest Portland


The Portland City Council unanimously adopted the Tryon-Stephens Headwaters Neighborhood Street Plan in November. With this plan, new neighborhood streets will have smaller footprints than traditional streets, which means they won’t generate as much stormwater runoff. The plan will be a guide for street improvements that include appropriate stormwater management techniques. This will allow neighbors, developers, and the city to improve streets and stormwater management more economically and without changing the feel of the street.

The Tryon-Stephens Plan:

  • Is the first collaboration between the Portland Bureau of Transportation and the Bureau of Environmental Services at the neighborhood scale
  • Furthers the application of new street and stormwater designs that are more flexible and more affordable than the traditional street and stormwater designs that were the only option until a few years ago
  • Moves beyond a one-size-fits-all approach to put improvements on local streets within reach for property owners and the city
  • Lays the foundation for cross-bureau collaboration and for thinking about street and stormwater infrastructure
