The Trestle Bridge Replacement was identified in the 2019 $14.5 million Parks Bond as a high priority project for Major Site Improvements. The pedestrian trestle bridge is over 37 years old and showing signs of its age. 

In 2019, a structural dive and review determined the existing trestle bridge needed replacing.  The replacement bridge will meet environmental regulations. 

Major Site Improvements for the Trestle Bridge will include:

• Removing existing timber bridge and pilings

• Replacing bridge with a single-span steel bridge structure

• Light penetration decking

• Viewing area with interpretive signage 

Engineering and design work will begin in February 2020 with construction anticipated to begin in late 2021 and be completed in mid-2022.

The North Water Walk Improvements were identified in the 2019 $14.5 million Parks Bond as a high priority project for Park’s Major Site Improvements.  Built in the 1982, the park structure requires modifications to maintain structural integrity, safety and meet requirements of the WA State Department of Natural Resources Lease Agreement.

Major Site Improvements for the North Water Walk include:

• Replacing concrete decking with new steel framing and 60% light penetration fiberglass decking, similar to the deck around Ivar’s Restaurant

• Replacing all wood timbers – bull rails and fascia boards with plastic timber

• Galvanizing existing handrails and repainting light poles

• Refurbishing picnic floats with new light penetrating fiberglass grating and plastic timber. Refurbishing benches and tables with Alaskan Yellow Cedar to match tables and benches along promenade

• Repainting Pilot House

Engineering and design work is scheduled from January 2020 through mid-2021 with construction anticipated to begin in mid-2021 through mid-2022.

The replacement of the Gene Coulon Memorial Beach Park playground was completed, and the playground opened on March 2, 2021.

The new play equipment was chosen based on a community survey conducted in the summer of 2020. Included are many all-abilities components: see-saw, group swing and individual swings, and two unique climbing structures. The project was funded by Washington state taxpayers through a State Direct Legislative Appropriation.

The structural repairs to eight facilities at Gene Coulon Memorial Beach Park have been completed after eight months of construction, which started in September of 2018.

Repairs to the facilities included:

• the replacement of structural steel and timber decking at the Ivar’s deck with new galvanized steel, fiberglass and aluminum grating;

• new aluminum finger piers at the Day Boat Moorage;

• removal of wood timber wave skirts at the North Water Walk and South Water Walk;

• new floatation and deck repairs at the Sailing Center;

• structural piling repairs at the Trestle Bridge;

• new plastic timber lagging at the Wave Break;

• repairs to the main dock and hinge replacements at the piers at the boat launch.

The structural improvements to the facilities replaced aging structural components and wood timbers with new galvanized steel and aluminum, fiberglass grating, and plastic timber. Increasing the life span, decreasing maintenance, increased safety, and meeting new aquatic environmental requirements, these improvements will provide years of service for park patrons visiting Gene Coulon Memorial Beach Park. 

In 2015, the plaza concrete pavers outside of Kidd Valley restaurant and the North Pavilion at Coulon Park were determined to be no longer functional. Originally installed in 1982, they were replaced them with poured-in-place concrete which are fully accessible, provide safe circulation, and will last for at least 50 years.
