earthworks - moving the earth for access roads, water management / infiltration / storage
TRANSCRIPT
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!).
Dams & swales integrated into a whole farm water catchment system.
