Roslyn Park Rain Garden

Description

URS Corporation designed a rain garden and infiltration trench and provided two workshops on behalf of the Pennsylvania Environmental Council (PEC) as part of a competition for municipalities within the Wissahickon Creek Watershed. Two winning sites were selected by PEC for rain garden installations. One site, Roslyn Park was awarded design, construction oversight and materials funding for the installation of a rain garden.

The former rock lined basin, located next to Marsden Soccer Field, was retrofitted from a flow-through basin into a biofiltration basin. An infiltration trench was also installed in connection with the basin to increase storage and infiltration capacity. The rain garden collects and treats runoff flowing off an adjacent parking lot. The finished rain garden provides Roslyn Park with water quality improvement since the water is filtered before it returns to the ground; stormwater runoff reduction, where previously the runoff from the parking lot was not captured or mitigated in any way; velocity reduction, preventing further erosion of nearby Sandy Run; and it also incorporates many native plant species back into the vegetation on site.  Because of the highly visible, accessible location of the project; it has provided educational opportunities for both municipal audiences as well as local homeowners.

The landscape plan for this project included 106 native shrubs and herbaceous plants including: Viburnum trilobum, Aronia arbutifolia, Panicum virgatum, Rudbeckia maxima, Asclepias incarnate, Lobelia cardinalis, Lobelia siphilitica, Monarda didyma, Iris versicolor and Carex stricta (see planting diagram below for details).
