Impact Statement

Purpose of Proposed Legislation and Background Information

This Stark Trunk Rehabilitation OF37/WZ01 Project is part of BES’ Large Scale Sewer Rehabilitation Program. Program goals are to rehabilitate or replace severely deteriorated sewer pipes, manholes, service laterals, and inlet pipes throughout the City’s sewer system and restore service life as economically and efficiently as possible

BES recently completed the construction of the Stark Trunk Sewer Relief Structure which provides flood protection to an area of the city that had experienced surface flooding. The current project will rehabilitate the existing, large diameter, combined sewer trunks both upstream and downstream of the relief structure. Rehabilitation goals are to address mortality risk while extending the remaining useful life of the sewers.

Financial and Budgetary Impacts

The proposed budget is a project estimate with a high level of confidence. This project is part of BES’ Large Scale Sewer Rehabilitation Program which is funded through FY 2024.

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

Community Impacts and Community Involvement

Environmental Services is repairing a large-diameter concrete sewer pipe along SE Stark Street between SE 6th Avenue and the Willamette River. Repairs will increase the sewer’s resiliency, extend its service life for 60 years or more, and help prevent sewage releases into building basements and streets. 

The project is located in the Central Eastside Industrial District in the Inner Buckman Neighborhood. Specifically, sewer pipe repair work will occur on SE Stark Street from SE Water Avenue to SE 6th Avenue.

Beginning in May 2020, Environmental Services conducted outreach to neighboring property owners, occupants, business, and the traveling public who might be impacted by sewer construction. Different methods of outreach have been utilized on this project, including mailed notification, hand-delivered flyers, phone calls, email updates and Nextdoor posts. The mailing list includes 947 recipients, the email list includes 261 recipients, and Nextdoor posts include approximately 2000 recipients. Some recipients have requested scheduled updates but have not expressed concerns about the project. Businesses we have heard from are advocating for at least lane one traffic to remain open on SE Stark next to the work zone to allow for easier access to their businesses during construction.

Prior to and during construction, public involvement, community outreach and public information services will focus on preparing businesses, property owners and occupants for construction. Particular attention will be given to maintaining close and cooperative communication with nearby businesses. Public involvement staff will develop and distribute project mailings, door flyers and other advance notifications to property owners and occupants within the project area; regularly update the project webpage; provide regular construction schedule updates via email to interested parties; and collaborate directly with businesses, property owners and occupants where unique issues may arise during construction.

Matt Gough, Environmental Services, has been the contact for Community Outreach and Public Involvement throughout design and will remain the contact throughout construction with support from JLA Public Involvement Inc.
