4. Learning Objectives At the end of this program, participants will be able to: 24 Green Roofs / 49 Water Conservation - Using Low Impact Development practices and techniques the participant will be able to evaluate site conditions, and collaborate with owners, civil engineers and landscape architects, to successfully design a sustainable site which seeks to replicate the natural surface and ground water hydrology thus protecting water quality and reducing run-off. 22 Environmental Education - Participants will be able to select and identify the appropriate pre-requisites and credits applicable to Low Impact Development practices to successfully complete sustainable site certification from three Green Building/Development Certification Programs.
