ASLA created a new online resource guide on green infrastructure. The guide contains lists of organizations, research, concepts and projects related to green infrastructure, and includes sections on: park systems, wildlife habitat and corridors, urban forestry, and green roofs (and walls). Developed for students and professionals, the resource guide contains recent reports and projects from leading U.S. and international organizations, academics, and design firms.
The guide is separated into four sections:
- Park Systems
- Wildlife Habitats and Corridors
- Urban Forestry
- Green Roofs (and Walls).

Using green roof technology to mitigate D.C. heat island effect

Other than increasing D.C.’s tree canopy, another method to mitigate the heat island effect is to construct green roofs, or a vegetative layer on the roof of a building. Also known as “rooftop gardens” or “eco-roofs”, attributes include increased vegetated cover, building temperature regulation (resulting in energy savings for heating and cooling costs as well as need for insulation); enhanced rooftop durability and less maintenance needs; reduced stormwater runoff; water filtration and restoration of natural habitats, among others.
