The Jamestown S’Klallam Tribe sought to incorporate the concept of Low
Impact Development (LID) long before design began on their new Longhouse
Market and Deli.
Prior to design, the Jamestown Tribe established two main goals to be met by
all Tribal developments. The first goal was to protect and enhance the natural
resources of the Jamestown S’Klallam Tribe. The second was to diversify and
strengthen the existing base of businesses owned and operated by the Tribe.
The new market is located in close proximity to two environmentally sensitive
areas; the Jimmycomelately Creek estuary, and the Tribe’s gooey duck clam
bed in Sequim Bay. The Tribe recognized that stormwater treatment was
paramount in protecting these crucial waterways and felt incorporating
LID stormwater solutions would offer the best solution to their immediate
challenges.
The Tribe’s desire to maximize parking spaces while meeting the high
environmental standards required by Washington’s Dept. of Ecology, made this
site a particular challenge. Soils at the site were not conductive to infiltration,
and a high groundwater level limited the options for utilizing LID.
The Filterra Bioretention System provided a solution to the site constraint and
infiltration challenges with its efficient pollutant removal and small footprint.
Two Filterra units which exceeded the Tribe’s expected goals for waterway
protection were installed and allowed available land to be saved for customer
parking.
