Green infrastructure is an integrated system of natural elements and low impact development (LID) practices that provide broad environmental benefits. Green infrastructure is becoming an umbrella term that other terms, such as LID, Better Site Design, Sustainable Stormwater Management, Conservation Design, and Smart Growth, fall under. LID is a management approach and set of practices that implement better site planning techniques to minimize adverse environmental impacts, and mimic natural systems. This presentation reinforces the principles of site sustainability by presenting design strategies and techniques that respect the natural balance of water and mimic the pre-development hydrologic regime. The program presents the benefits of integrating stormwater close to the source (particularly as part of the landscape design) as an alternative to conventional "end-of-pipe" solutions. A series of LID techniques that are effective at controlling the peak rate of stormwater runoff, promoting groundwater recharge, and providing water quality treatment will be presented. A case study of the Frick Chemistry Laboratory at Princeton University will be presented that discusses design and construction of LID components and their impact on the sustainability of the project.

1. To teach and reinforce the principles of sustainable site design
2. To identify and understand progressive strategies that provide a “greener” or more sustainable approach to site design
3. To provide examples of green infrastructure/LID techniques that may be applicable for projects and properties
4. To demonstrate the benefits of LID as an alternative to conventional “end-of-pipe” site design practices
