Manage and cleanse rain water runoff on-site.
The natural hydrology of the site landscape
(infi ltration, runoff , and evapotranspiration)
should be replicated based on historic, natural,
undeveloped ecosystems in the region to the
extent practical. Retain as much rainwater as
possible using bioretention and infi ltration
features such as bioswales and planting beds,
that allow vegetation to absorb, cleanse, cool,
infi ltrate, and evapotranspire water into
the atmosphere. Surface water runoff from
non-permeable roadways, alleys, sidewalks,
and parking surfaces can be directed into
bioretention features seamlessly installed
within rights-of-way, parkways, and other
corridor features. Curbs and gutt ers may
need to be retrofi tt ed to bett er direct water
into landscape features. Treat runoff on-site
to improve the water quality of downstream
water resources. Porous paving practices,
bioretention features, and native landscaping
support sustainable rainwater treatment.
