The City of Rowlett holds the Tree City USA designation developed by The National Arbor Day Foundation (NADF) for cities dedicated to conservation and environmental awareness. To become a Tree City USA, Rowlett passed a tree ordinance, organized a tree board and proclaims and celebrates an Arbor Day. The City of Rowlett’s significant efforts to earn this important distinction can be seen in its median beautification projects as well as tree plantings in area parks, greenbelts and city grounds. Rowlett was first named Tree City USA in 2000.
