urs, why worry about stormwater
DESCRIPTION
This is a presentation prepared for the Stormwater Treatment BMP Workshop, sponsored by the Johnson County, Kansas Stormwater Management Program, and held in December 2011.The first presentation illustrates how urbanization affects water movement through the landscape and how green infrastructure can help restore ecological function to the built environment. The second presentation was an introduction to rain garden and bioretention construction for commercial applications (rather than residential yards).For more information on these materials, contact:URS Green Solutions TeamOverland Park, KansasDavid Dods, Senior Environmental Engineer, [email protected], 913.344.1022Jessi Veach, Civil Engineer, [email protected], 913.344.1029Todd Bond, P.E., Senior Civil Engineer, [email protected], 913.344.1010David Kocour, Environmental Scientist, [email protected], 913.344.1058TRANSCRIPT

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.
