TTF works to create functional landscapes and healthy communities by installing, maintaining rain gardens and riparian buffers. Rain gardens and riparian buffers are native plant installations that absorb and filter water and provide wildlife habitat.

Rain Gardens
A rain garden is a shallow depression that can be planted with a wide variety of flowers, grasses, trees, and shrubs. Rain gardens and other green infrastructure store and purify rainwater where it falls and allow it to soak into the ground, helping to prevent the combined sewer system from overflowing and polluting our waterways. When it rains, rainwater passes over — and mixes with — oil, dirt, chemicals, pesticides, and other pollutants as it flows over roads, lawns, and other hard surfaces.

What are the Benefits of Rain Gardens?

  • Cleaner water
  • Attractive gardens with colorful flowers
  • Habitat and food for wildlife
  • Reduction in rainwater runoff

Riparian Buffers
A riparian buffer is a zone of vegetation that runs parallel to the banks of a body of water. Riparian buffers are important for protecting water resources from non-point source pollution and providing bank stabilization and aquatic and wildlife habitat.

Examples of previous restoration work include:

  • Installation of a rain garden at Vernon Park, a neighborhood park in Germantown
  • Transformation of Clearview Community Park, a 5,000 square foot vacant lot in Philadelphia’s Germantown/East Mt. Airy neighborhood into a garden of native plants
  • Creation of a 10,000 square foot riparian buffer and outdoor classroom at Glenside Elementary School
  • Installation of a 15,000 riparian buffer and outdoor classroom along Rock Creek, a first order stream of the Tookany Creek located behind Cedarbrook Middle School
