Rain Gardens

The New York City Department of Environmental Protection (DEP) is building rain gardens and other types of green infrastructure to manage stormwater and improve water quality in local waterways.

Rain Gardens

Green infrastructure is a cost-effective way to help create a sustainable New York City

  • Beautifies neighborhoods.
  • Purifies air.
  • Reduces temperature during hot weather.
  • Improves street drainage.
  • Reduces puddles and ponds.


How Rain Gardens Work

Rain Garden

A rain garden may look similar to a street tree pit or a small garden, but there are some key differences. Here’s how you can tell the difference:

  1. Curb inlet - The inlet allows water to flow into the rain garden as it flows down the curb toward the catch basin.
  2. Outlet - Larger rain gardens also have an outlet. If the rain garden fills to capacity, water can exit through the outlet and continue into the catch basin on the street corner.
  3. Stone Strip - The stone strip allows people to step out of their cars without damaging the plants.
  4. Plants - All rain gardens have plants and grasses which have been carefully selected to ensure they can survive on busy New York City streets.
  5. Soil - The soil is graded so that water ponds in the center of the rain garden.
  6. Tree Guard - All rain gardens have tree guards around them that protect the plants and keep people and dogs from walking inside of it.
  7. Tree - DEP plants trees in rain gardens as often as possible. Trees benefit neighborhoods by lowering temperatures in hot summer months, improving air quality, and providing habitat for birds and butterflies.
