Starting in 2007, a group of Tyler parents worked to turn what was a fenced, asphalt lot into an outdoor learning environment that would also reduce stormwater runoff from the school grounds.

With funding from the Morris & Gwendolyn Cafritz Foundation, the National Fish and Wildlife Foundation, the CVS/Caremark Charitable Trust and others, the Outdoor Classroom was created. The Outdoor Classroom contains a rain garden, native trees and plants, a seating terrace, and a vegetable garden.

Today, the Tyler Outdoor Classroom reduces stormwater runoff into
the Anacostia River, and provides habitat for birds and pollinators. It also provides outdoor play space, educational opportunities, and teaches Tyler students about protecting the environment.
