stormwater runoff.
Depth
A typical rain garden is
between 4-8 inches
deep.
This depth,
proportionate to the
surface area being
drained, helps ensure
that water soaks back
into the ground instead
of ponding.
Plant Choices
Choose native plants
based on need for light
and moisture.
Native
plants live longer and
are more tolerant of
local weather and
soil conditions!
Location
Rain gardens are often
located at the end of a
roof gutter or drain
spout as a buffer

Soil
A good soil mix for
a rain garden is
60% sand,
20% compost and
20% topsoil.
