n June
2007 the Whidbey Island Conservation District (WICD) partnered with
Goosefoot, the Puget Sound Partnership, and local volunteers to
construct a rain garden at Bayview High School. The
approximately 100 square foot rain garden will capture a portion
of the stormwater run-off generated by the high school, clean
it, and slowly let it get absorbed into the ground.


A rain garden is a key
feature in Low Impact Development (LID). LID is a new approach
to manage storm water run-off. In a mature Pacific Northwest
forest, much of the rain fall evaporates or gets absorbed into
the ground to recharge aquifers. Once a piece of property is
developed, the hard surfaces (streets, parking lots, roofs,
sidewalks, etc), don’t allow the run-off to be absorbed back
into the soil and cleaned. The hard surfaces also increase the
speed of the run-off. The oil, metals, and pollutants lying on
those surfaces move with the run-off as it makes its way to
underground pipes and eventually enters the Puget Sound.


LID, first and foremost,
advocates for the preservation of native vegetation. But if a
property is developed and loses its native vegetation, there are
many LID techniques that can be implemented to clean and slow
down the rain water the way a forest would. A rain garden is
one of those ways.

The new rain garden at Bayview High School will capture the rain
water that falls on part of the building by connecting a down
spout to the garden. The rain garden is located at the bottom of
a small hill so some additional surface water run-off will also
be captured and cleaned.
The superintendent of the
South Whidbey School District, Dr. Fred McCarthy, was on hand to
help with the construction of the rain garden and expressed his
appreciation to the volunteers.
Much of the financial
support for this project came from the Puget Sound Partnership.
“Rain gardens are a wonderful way to improve the aesthetic value
of an area, while also improving the environment,” said Linda
Lyshall, Puget Sound Partnership.
Additional design and
construction assistance were provided by Sara Birger, landscape
designer, of Taproot Design and Blue Star Rockery.
The Goosefoot Community
Fund will be watering the garden throughout the summer. “The
rain garden is a beautiful and educational demonstration,” said
Debbie Torget, the Chief Operating Officer for the Goosefoot
Community Fund. “Goosefoot was very happy to participate with,
and learn from, the fine folks of the Conservation District and
the Puget Sound Partnership, and we’re looking forward to our
future joint efforts.”
The WICD planners and
engineers provide free non-regulatory technical assistance to
Whidbey Island residents. In August of 2006, the WICD included
Low Impact Development and Backyard Conservation to its farming,
natural resource, and engineering programs. This rain garden
workshop was offered as part of the WICD LID program.
“Rain gardens are one example of a LID tool that can be
installed just about anywhere,” says WICD representative, Kelly
Donahue, “We hope this garden will inspire residents of Whidbey
Island to construct rain gardens at their homes.”
