The Yauger Park Low Impact Development (LID) Project provides for enhanced water quality treatment, additional storage volume and improvements to the recreational facilities at the City of Olympia’s Yauger Park regional stormwater facility. In this case study, the permeable pavement (porous Asphalt) at the Yauger Park Low Impact Development (LID) Project is examined. Federal funding under the “American Recovery Act” was used to build a demonstration project employing environmentally sensitive Best Management Practices (BMPs). There are several environmental innovations being used at this one site, and permeable pavement is just one.
The Yauger Park Low Impact Development (LID) Project provides for enhanced water quality treatment, additional storage volume and an enhancement to the recreational facilities at the City of Olympia’s Yauger Park regional stormwater facility. This green infrastructure stormwater treatment project includes bioretention areas (Wetland and Wetponds) that harbor native flora and fauna to promote biofiltration. The bioretention areas of wetlands and wet ponds function as educational and recreational purposes for the community. It also functions to innovate Best Management Practices within each other for demonstration for private property owners and municipal jurisdictions.
The “Moving Green Infrastructure Forward” Project is a two-year stormwater monitoring project at Terminal 91, Port of Seattle. Using the Splash Boxx, a bioretention planter box used for stormwater management, the project compares the pollutant removal efficiency two bioretention soil mix designs: one with conventional sand/compost and another with volcanic sand/compost. Splash Boxx is recognized by the Washington Department of Ecology as equivalent to a bioretention facility, so the project was easily approved by the Port of Seattle. It was also designed consistent with City of Seattle guidelines for bioretention planter boxes.
Kitsap County planners developed a vacant lot in the Manchester Neighborhood as a public gathering space with Green Stormwater Solution treatment cells for the 100-acre neighborhood. Also designed to manage a perennial stream, this project demonstrates an opportunity for development areas to treat large quantities of runoff where natural features and space are nonexistent.
Pacific Northwest salmon sustain ecosystems we depend upon, yet road and highway culverts block them from reaching upstream nesting redds. A 2013 court decision mandates culvert infrastructure be replaced with more environmentally sound solutions. Lyon Creek Flood Mitigation (LCFM) is an award winning example of 21st-century green infrastructure improving wetland parks near a suburban shopping center.
