Consulting provided design services for the complete rebuild of the Tumwater Falls Adult Holding and Rearing Facility. The rebuild focused on integrating new rearing facilities within the public park framework, allowing the public to become familiar with the rearing operations and process that occur at a hatchery, leading to public education of the importance hatcheries play in the built environment.
The rebuild replaces the existing holding ponds and intake with a new publicly accessible hatchery that incorporates a new fish ladder with public viewing windows, pump station, adult holding/ rearing ponds, spawning area, pollution abatement pond, restrooms, backup generator, and storage for culture equipment. Extensive stormwater management practices were used to provide quality return water to the Deschutes River. Low-maintenance landscaping was used along with features intertwined in the park setting to identify the historical significance of the site to the City of Tumwater.
Additional support during the permitting process where engineers participated in procuring building permits from the City of Tumwater. The project also included coordination with the Olympia Tumwater Foundation and City of Tumwater (Parks, Historical Society, floodplain administrator, and Building Department).
