Learn about low impact development techniques, including Green Roofs and Green Buildings


LID techniques include:

  • Site design
  • Open channels
  • Rain barrels and cisterns
  • Vegetated buffers and swales
  • Rain gardens
  • Green roofs

Green roof systems (or roof gardens) are an LID technique where the building's roof is planted with vegetation on a specialized drainage infrastructure. Green roofs capture, filter, and temporarily store rainwater. Green roofs are being combined with other green building techniques to conserve the natural resources through the efficient and intelligent use of energy, materials, water, and the building site.
