Parks and Civic Spaces

Building healthy, active communities

Recreational facilities contribute to a community’s livability and support quality of life for residents. Parametrix partners with our clients to create places that promote healthy lifestyles, protect critical areas and natural systems, and restore important ecological functions. Well-designed and maintained parks and open spaces will help to positively shape the community’s image and increase property value.

Manchester Stormwater Retrofit
Manchester, Washington
Client: Kitsap County

An empty lot in Manchester now does double duty as a pleasant community space and a workhorse to clean polluted runoff for Puget Sound. The Manchester Stormwater Park is the Puget Sound area’s first stormwater park, and one of only a few such combined treatment/recreation facilities in the nation. The project was initially designed to replace an aging and undersized outfall. However, Kitsap County recognized a unique opportunity to treat a larger drainage area and correct some flooding issues as well as enhance the community. The Stormwater Park treats stormwater from roads, parking lots, commercial property, and residential areas from approximately 100-acres upland of downtown Manchester to today’s strict standards through innovative Green Stormwater Solutions (GSS) using soil and plants. Treatment cells located around the perimeter of the park process storm flows through engineered filter media and plants that can tolerate periods of inundation, and also clean the runoff using filtration and absorption processes. A unique design feature of the park is a spiral rain garden that intercepts low flows from groundwater and very light storms and treats it through bioretention soil mix and plants in the rain garden. Because the rain garden intercepts the relatively constant low flows, the life of the more expensive engineered treatment media in the treatment cells will be extended. Treated water is collected in a lower drainage system and subsequently discharged to a new outfall at the beach in Pomeroy Park.

"Over the past year I have had the pleasure of working with the Parametrix team on the City's Storm and Surface Water Utility Comprehensive Plan Update. This has truly been a collaborative effort... working alongside city staff from a variety of departments and programs in addressing policy, regulatory and natural resources challenges."
