This is a presentation given at the 2011 Stormwater BMP Installation and Maintenance Workshop, sponsored by the Johnson County, Kansas Stormwater Management Program, and held at Johnson County Community College in December.

Two files have been posted. The first presentation (this one) illustrates how urbanization changes our landscape and the way water moves through it, the consequences of those changes, and how green infrastructure can help restore ecological function to the built environment.

The second presentation is an introduction to rain garden and bioretentionconstruction for commercial applications (rather than residential yards).

These materials were developed by the URS Green Solutions Team in Kansas City. Feel free to contact us with any questions about these materials.

Rain Gardens and Bioretention

Catch stormwater near the point of generation, Slow it down, Promote

infiltration, Filter pollutants, Restore habitat and ecological function,

Create beauty with our stormwater systems.
