Green Street
Systems open bottomed tree filter systems are a Low Impact Development
(LID) solution to stormwater management providing direct infiltration
of stormwater runoff close to its source.
Green Street Systems (GSS) tree filter systems can provide
sustainable, LID stormwater management to new development, redevelopment,
and tight, urban retrofits. Unlike conventional tree box filters,
the GSS tree filter system frame is open on the sides to allow for
lateral root migration and healthy tree growth.
Also unlike concrete box systems, GSS tree filter system
design includes a pretreatment sediment collection sump to catch
trash, sand, and sediment prior to entering the filtration system.
This basin can be easily cleaned from the curbside with DPW
vactor equipment. GSS tree filter systems use bioretention
and soil filtration to collect and filter stormwater runoff through
layers of mulch, soil media, plant roots, and gravel.
Pollutants, such as oil, grease, bacteria, nitrogen, phosphorous,
and heavy metals, are retained, broken down or absorbed. Because
the system is open bottomed, treated water is then infiltrated into
the ground, but can be directed into a traditional stormwater collection
system or underground storage chambers if infiltration is not possible. Green Street Systems sustainable
tree filter system designs reduce the impact of development, contribute
to green space, add value to the property, and improve quality of
life. GSS tree filter systems can
earn LEED points in the Sustainable Sites subcategories for Stormwater
Management: Quantity Control and Quality Control and for Materials
and Resource Selection. |
