The City of Wilsonville, Oregon (the “City”) is requesting Proposals in order to select a qualified
consultant to provide professional services for the Coffee Creek - Day Road Sewer Extension
(“Project”). Consultants are invited to demonstrate their experience and qualifications in
performing work directly related to the services required by responding to this Request for

procedures of OAR 137-048-0220. This Project ☐does ☒ does not involve federal funds.
I. Project Description
The Coffee Creek industrial area is approximately 258 gross acres south of Day Road, planned to
be used for Regionally Significant Industrial purposes. In 2016, the City adopted the Coffee
Creek Urban Renewal Plan to build utility infrastructure to accommodate growth in the area.
The Coffee Creek – Day Road Sewer Extension Project “Project” was identified and included in
the Urban Renewal Plan to extend sanitary sewer to serve properties south of Day Road in the
Coffee Creek industrial area and properties north of Day Road in the Basalt Creek industrial
area.
The Project is identified in the 2014 Sanitary Sewer Collection System Master Plan and the
Basalt Creek Utility Infrastructure Concept Plan, 2017, and a preferred pipeline alignment and
profile selected by the City in 2019 (See Attachment B). The preferred alignment extends a 15”
sewer main on Day Road from Garden Acres Road to Boones Ferry Road and will provide
additional capacity to support industrial development within the Coffee Creek and Basalt Creek
industrial areas.
The City anticipates that the project will include, but is not limited to, design and coordination
of the following items:
A. Engineering Design Studies
Engineering studies will include, as a minimum, geotechnical investigations to document
the extents of boulders and bedrock along the pipeline alignment, but may include
other studies as determined by the design engineer and approved by the City.
B. Survey and Utility Location
The design engineer will coordinate all required survey for design, coordination, and
verification of all utilities within the project boundaries, and post-construction survey.
C. Layout of Sewer Main and Alignment
As part of the Basalt Creek and Coffee Creek Sanitary Sewer Concept Plan (Dated May 1,
2019), a preferred alignment and profile was selected by the City. The preferred
alignment extends a new 15-inch diameter sanitary sewer main from the existing
manhole near 24925 SW Garden Acres Road to the intersection of SW Day Road and SW
Boones Ferry Road. The Basalt Creek and Coffee Creek Sanitary Sewer Concept Plan can
