DATE: May 23, 2025
SUBJECT: Surface Water Fund — Gilliam Creek Fish Barrier Removal and Habitat Enhancement
Project No. 99830105
Recreation and Conservation Office Brian Abbott Fish Barrier Removal Grant Award
ISSUE
Accept a Recreation and Conservation Office (RCO) Brian Abbott Fish Barrier Removal Board grant
award for Gilliam Creek Fish Barrier Removal Project in the amount of $300,000 for preliminary design.
BACKGROUND
The Gilliam Creek Fish Barrier Removal and Habitat Enhancement project was established as a City
CIP project in 2019, it is a priority project with Water Resource Inventory (WRIA) 9 and the Salmon
Recovery Fund Board. The goals of the project are to restore fish passage between Gilliam Creek and
the Green River, enhance habitat, and maintain or improve flood protection and maintenance and
operation of the flap gate system.
DISCUSSION
In 2022, staff applied to the Brian Abbott Fish Barrier Removal Board grant program managed by RCO
for design funding for the Gilliam Creek project. The City was initially unsuccessful in this grant round
and was placed on a contingency list if funding were to become available. In late 2024, due to State
delays and projects unable to accept funding, the Board offered the City the full award of $300,000. City
staff have been in negotiations with RCO staff to adjust our scope of work due to changing project
needs and constraints. This funding will be used to advance the alternatives analysis and design
development phase and complete 30% design. The City is under contract with Otak for this work.
FISCAL IMPACT
The City was awarded a $300,000 grant from the RCO for Gilliam Creek Fish Barrier Removal. This
grant has a 15% match.
Project Budget
