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. |
