Updated – Register for Watershed Academy Webcast on the “National Stormwater Calculator”  


--Webcast rescheduled due to Government Shutdown

              Join us for a Watershed Academy Webcast on Oct. 23, 2013 from 1:00 pm to 2:30 pm Eastern on the new “National Stormwater Calculator.”  This new calculator is designed for anyone interested in reducing runoff from a property including: site developers, landscape architects, urban planners, homeowners and others.  It can help users decide which stormwater management practices to install such as a rain garden or a green roof.  This calculator is a desktop application that estimates the annual amount of rainwater and frequency of runoff from a specific site anywhere in the United States (including Puerto Rico). Estimates are based on local soil conditions, land cover, and historic rainfall records.

                The Webcast presentation slides are posted on the Website and archives of the Webcast will be available after the Webcast for those that cannot attend the live Webcast.
