Design Consultant Selection and Agreement
ISSUE
Approve a contract with KPG, Inc. to provide project feasibility and design services for the Storm
Water Quality Retrofit Project in the amount of $282,440.
BACKGROUND
The Storm Water Quality Retrofit Project is intended to improve water quality at select City -owned
and operated stormwater discharge points at various locations throughout the City. The goal is to
reduce the amount of stormwater-generated pollutants that are being discharged to the Green-
Duwamish River from City roads in order to improve water quality conditions for endangered salmon
species and other fish and wildlife. The design phase of this project entails the evaluation and
prioritization of eight stormwater outfalls identified by City staff. Up to four of the sites will be designed
to 100%, for which construction funding sources will be sought at a later date.
DISCUSSION
Staff reviewed the current MRSC Consultant Roster and an RFP was sent to several dozen design
firms. Three firms submitted proposals; KPG, Inc., TetraTech and PACE Engineering. The proposals
were scored according to predefined criteria by a three -person selection committee. KPG was the
highest-ranking firm among all three committee members and was invited to interview. KPG has
designed the Annual Small Drainage Program since 1991 as well as other surface water projects
and Public Works staff continues to be very satisfied with their work.
FINANCIAL IMPACT
The proposed fee for the design work is $282,440 for the Storm Water Quality Retrofit Project. The
2019 design budget is $299,000 and a Department of Ecology Stormwater Financial Assistance
Program grant will fund $244,375 on a reimbursable basis.
RECOMMENDATION
Council is being asked to approve a consultant agreement with KPG Inc, in the amount of $282,440
for project feasibility and design of the Storm Water Quality Retrofit Project and consider this item
on the Consent Agenda at the August 5, 2019 Regular Meeting.

Task 6 Assumptions:
• The level of effort for final design of four selected retrofit sites has been developed prior to
selection of the retrofit locations and configurations. Selection of retrofit alternatives with a size
and complexity greater than assumed may require modification to the scope of work, potentially
reducing the number of sites to be taken to final design and/or elimination of the 100% design
subtask.
