integrated Storm Water Management (iSWM)™

Development and redevelopment by their nature increase the amount of imperviousness in our surrounding environment. This increased imperviousness translates into loss of natural areas, more sources for pollution in runoff, and heightened flooding risks. To help mitigate these impacts, 55 local governments are cooperating to proactively create sound storm water management guidance for the region through the integrated Storm Water Management (iSWM)™ project.

The iSWM™ Design Manual for Site Development is designed to assist the Community in meeting water quality protection, streambank protection and flood control goals by managing stormwater on a site-by-site basis throughout all phases of development.

We are about to put forward Licensing Agreements for those cities who want to participate in the use of the manual.

For the most current information, please refer to the iSWM website.
