West Portland Town Center Stormwater Systems Plan (WPTCSSP)

Sewer and Stormwater
In Planning
Environmental Services is in the planning stages for a new stormwater systems plan for West Portland Town Center (WPTC). The plan will investigate current conditions of stormwater systems, including streams in the area, to explore options for necessary improvements in the WPTC planning area.
Environmental Services is currently in the planning phase for this project. A construction timeline has not been scheduled yet.

Take Our Impact Surveys

If you have a business, organization, or live in or around the West Portland Town Center area, please complete the optional questionnaires below. These surveys will help Environmental Services design and build projects that reflect the needs of the community. 

  • Stormwater Survey: For all that live in or work around the West Portland Center.
  • Basement Moisture Survey: For occupants and property owners who have experienced street flooding, sewer backups in basements, or groundwater seepage.

Overview

WPTCSSP will look to design a future stormwater system plan for the West Portland area. The plan will investigate and explore options to improve existing conditions to support future development, as called for in the West Portland Town Center Plan (The WPTC Plan) adopted by Portland City Council in March 2023. 

WPTCSSP will help protect the needs of the public and the environment by ensuring the plan area has adequate system capacity and help to reduce costly flooding, soil erosion and landslide risks, as well as prevent sewage releases to homes, businesses, streets, greenspaces, rivers, and streams.

Plan Area and Map

The WPTCSSP planning area is centered around the intersections of SW Capitol Highway, SW Taylors Ferry Road, and SW Barbur Boulevard. Historically called 'the crossroads' it stretches north to SW Dolph Court, south to SW Pomona Street, and west to east from roughly SW 52nd to 30th Avenue. 

The plan will also address stormwater runoff, and pollution concerns that impact two watersheds in South and Southwest Portland: Fanno Creek Watershed and Tyron Creek Watershed

General Schedule 

In June 2023, Environmental Services began developing a plan for the West Portland Town Center area (see plan map). The project team will continue planning through 2026.

Design and construction of the stormwater system or implementation of other possible solutions will occur after planning has concluded and may take several years to complete.

What’s Happening Now?

WPTCSSP is in the initial planning phase. The project team will center work and collaboration with city bureaus and partner agencies, service providers, environmental specialists, community members, and other interested partners to continue planning throughout 2025. 

Project Background

The WPTC area is the most culturally diverse region of Southwest Portland. While the region is home to multiple parks and natural trailways, language-immersion schools, research and health universities, international supermarkets, popular ethnic restaurants, religious and community service organizations, as well as a robust network of small businesses and large corporations; the area is considered to have significant population and housing undergrowth due to the lack of public improvements.  

Unlike other Portland neighborhoods and town centers, the WPTC district lacks pedestrian and biking infrastructure, on-street parking, bussing, connecting light rail service, and access to multifamily housing options. Most importantly to this planning effort, the WPTC area needs significant repair and upgrading to its stormwater infrastructure. There have been many reports of repeated street flooding, excessive sewage backups in basements, landslide hazards or risks, and the need for traffic calming support.

West Portland Town Center Plan (WPTC Plan)
The WPTC Plan lays out a vision for a healthy, connected, and multi-cultural town center and includes an action plan to meet the diverse needs of current and future residents and businesses.

BES Commitment to Building Healthy and Sustainable Communities 

WPTCSSP will play a major factor in building and connecting vibrant communities in the WPTC area. It will also help support equitable housing, accessible public transportation, employment, and community service initiatives brought forth in The WPTC Plan, sponsored by the Bureau of Sustainability and Planning (BPS). 

The WPTC Plan presents a vision for a healthy, connected, and multi-cultural town center, and includes an action plan to meet the diverse needs of current and future residents and businesses. The WPTC Plan and other subsidiary projects of the 2035 Comprehensive Plan will aid in the preparation for and management of expected population and employment growth, as well as plan for major public investments between now and 2035. 

Project Goals

Environmental Services is developing a sanitary and stormwater systems plan to better serve West Portland Town Center while providing adequate capacity to support future community development. 

Project goals will prioritize and center the following:

(1)  Educating the public about the sanitary and stormwater system in their neighborhoods.

  • From previous outreach during WPTC planning, we heard the need for education around infrastructure.  BES will provide education and information about stormwater and the resources available to help manage it.

(2)  Identify areas where BES can make improvements to the sanitary and stormwater system that will benefit current and future residents and businesses, outcomes may include:

  • Programs to work with property owners to reduce the amount of stormwater runoff from existing development.   
  • Infrastructure projects to address existing system issues and improve system capacity to serve future growth.   
  • Implementation of regional stormwater facilities to reduce impacts of stormwater runoff on local streams.   
  • Stream enhancement projects to minimize erosion and flooding, improve water quality and overall watershed health.

(3)  Work with our other city agencies and bureaus to provide alternatives/solutions as a OneCity approach.

  • The City is changing to a new structure where the infrastructure bureaus will be unified. This will allow for easier cross collaboration and a unified solution approach.

Events

FREE Stormwater Stars Workshops Sunday, October 27, 2024, 10 am to 12 pm – Village Park in Multnomah Village, SW Portland. This will be a joint workshop between the Westside Watershed Resource Center in partnership with the Multnomah Neighborhood Association and the Multnomah Village Business Association. Participants will plant native plants on the hillslope at Village Park. 

Stormwater Stars workshops provide ideas on managing rain that falls around the spaces where you live, work, and play. You’ll receive an overview of different ways to handle stormwater issues and get plenty of hands-on practice in restoring soils, nature-scaping with native plants, creating porous pathways, and more! All workshop attendees will receive a free native plant as a thank-you for participating! Workshop size is limited, so sign up soon to secure your spot. Pre-registration is required. You can learn more and sign up at www.stormwaterstars.org/events. For questions, email hello@stormwaterstars.org or call 503-865-6759.
