Impact Statement

Purpose of Proposed Legislation and Background Information

The Sellwood Sanitary Sewer Extension Project is part of BES’s Sewer Extension Program. This program focuses on constructing sewer extensions to serve properties that do not currently have a public sewer available in the adjacent public right of way.  The new extensions allow for resolution of non-conforming sewer connections. 

The purpose of this legislation is to authorize a construction contract for project no. E11162, to construct approximately 7,200 feet of mainline sanitary sewer pipe and 153 individual property sewer laterals in the Sellwood neighborhood. There will be no change to the overall CIP program or City policies.

Financial and Budgetary Impacts

This project is part of BES’ Sewer Extension Program, which is funded through FY ‘22-23. The proposed project estimate has been assigned a high confidence level.

This project will neither generate nor reduce current or future revenue. No new City positions will be created.

Community Impacts and Community Involvement

The Sellwood Sewer Extension project area includes residential homes and business in the Sellwood-Moreland, Sellwood-Tacoma, and Sellwood-Westmoreland neighborhoods. The project is generally bounded by SE Henry Street to the north, SE Linn Street to the south, SE Oaks Park Way to the west, and 99E to the east.

Environmental Services has conducted extensive community outreach and public involvement activities in the area with property owners and occupants and neighborhood associations that will be affected by the project. During the design phase of this project, a variety of outreach methods and public involvement initiatives have been utilized to achieve this, including:

  • Multiple project mailings and informational flyers sent to homes throughout the area.
  • Web, email, and social media updates
  • Multiple personal letters sent directly to impacted properties.
  • Distribution of sewer lateral branch maps to coordinate locations of sewer service laterals to every impacted resident.  
  • One on one consultation with impacted properties for technical issues and financial assistance guidance
  • Community workshop for SMILE (Sellwood-Moreland Improvement League)

Matt Gough, Emily Volpert, and Tina Wilson of Environmental Services are the primary contacts for community outreach and public involvement for the design and construction phases. 

Significant Concerns:

Per 17.33.050, Converting Nonconforming Sanitary Sewer Connections, properties must convert or abandon nonconforming sewers within 180 days of the date on the notice of sewer availability.

Property owners must pay or finance the sewer conversion charges prior to connecting. For a typical residential property, the sewer conversion charge is $8,299 for fiscal year 22/23 and increases each July 1. BES has made efforts to distribute information regarding our financial assistance loan programs that can be used to finance sewer connection fees and private plumbing costs.

Positive Outcomes:

Although there is a financial impact to affected residents, resolving non-conforming sewers through sewer extensions provides positive benefits. Many of the non-conforming sewers in the area are aging and some have failed. Maintenance of non-conforming sewers, particularly private lines in the right-of-way can be cumbersome and expensive. Providing BES-maintained sewers to these properties is a long-term benefit.

100% Renewable Goal

This project neither contributes nor takes away from the City’s goal of meeting 100 percent of community-wide energy needs with renewable energy by 2050.
