EPA has launched the third annual Campus RainWorks Challenge, a green infrastructure design challenge for college and university students. Student teams, working with a faculty advisor, will submit design boards, a project narrative, and a letter of support describing a proposed green infrastructure project for a location on their campus. Registration opens Sept. 2 and ends Oct. 3. Registrants must submit their entries by Dec. 19. Winning teams will earn a student prize of $1,000-$2,000 to be divided evenly among student team members, and a faculty prize of $2,000-$3,000 to support green infrastructure research or training.
