Green Infrastructure at the micro scale would include the individual practices and techniques employed to protect and preserve water resources. It’s host of practices, both structural and non-structural, are applicable both pre- and post- development to manage water quality.  The structural practices can be as simple as a roof top drain disconnection from the standpipe and directing water flow across the lawn to allow it to infiltrate on site or can be as complicated as an intensive green roof that supports trees, gardens and walking paths, retaining  and using rain water to sustain the flora and fauna.  The non-structural components, although harder to implement, provide the largest benefit as they can regulate how development occurs or can conserve a sensitive area.  When the practices that GI are comprised of are put in place and properly functioning they:

• Reduce the impervious area at a site
• Implement infiltration to the maximum extent possible
• Generate less runoff
• Utilize building site characteristics to manage runoff
• Reduce infrastructure operation and maintenance costs
• Conserve open & green space and ultimately,
• Protect water quality.
