The document provides guidance for designing and creating a rain garden, including choosing plants based on light and moisture needs, making the garden 4-8 inches deep for proper water infiltration, using a soil mix of 65% sand and 25% compost, locating the garden near downspouts and ensuring it is 5-10% of the impervious surface area while avoiding septic systems, and including an overflow outlet.

4. Choose plants based on need for light,
moisture, and soil. Vary plant structure,
height, and flower color for seasonal appeal
and butterfly habitat.
A typical rain garden is between 4 and 8 inches deep. This
depth, proportional to surface area, helps ensure water will
infiltrate quickly and not pond longer than 3 days.
A good soil mix for rain gardens is 65% sand
and 25% compost. In heavier soils, gravels
and stone may be added to improve
infiltration.
Often located near down
spout as a buffer between
the lawn and the street.
A rain garden is typically 5 – 10% of the
impervious surface that generates runoff.
Avoid the area over a septic system.
The garden must include an overflow outlet
that will transport excess rainfall to a proper
location (not your neighbors lawn!).
