This manual is intended as a technical resource for community-based organizations, city agencies, and landscape professionals who are addressing vacant land issues in Philadelphia’s neighborhoods. The manual describes the clean & green approach, which is designed to maintain or “stabilize” vacant lots, preventing further deterioration until future uses for the land can be found. This process involves a thorough cleanup and removal of debris, basic landscape improvements such as planting grass and trees, installation of barriers to prevent illegal dumping, and ongoing maintenance. It will serve as a reference to those who are planning lot stabilization projects and as a complement to training programs
