Rain Garden to the Rescue



Rain Gardens to the Rescue

Students will measure the impervious area on campus, including the school building and paved surfaces, in order to calculate the size of a rain garden large enough to filter the “first flush” of runoff from a rainstorm; then observe the flow of runoff on school property and determine locations where a rain garden should be located in order to filter water before it enters ditches, creeks or storm drains; design a rain garden, and install it.
