A practical 1.5 day short course for landscapers, designers, maintenance care providers and volunteers.
Rain gardens are vegetated areas designed and built to accept stormwater runoff from surfaces including rooftops, roads and compacted soils. Rain gardens are increasingly being used by homeowners and municipalities to reduce the impact of stormwater on local waterways and the Long Island Sound.

Rain Gardens in Connecticut: A Design Guide for Homeowners
The guide provides simple yet detailed information on how to construct a rain garden at your own home, including a plant list.
May 2012 Rain Garden
NEMO's most recent rain garden on the Haddam Cooperative Extension grounds is in the back of the building. One of the building's downspouts was connected to the rain garden via an underground pipe. The main purpose of this demonstration rain garden was to be able to document its creation for use on this website and Smartphone application (see details on Rain Garden App).
See a short video below, and read more about rain gardens and this installation at the Record Journal's website.
September 2002 Rain Garden
Our first rain garden (actually two side-by-side) on the Haddam Cooperative Extension grounds was a collaboration with the Department of Natural Resources Management and Engineering (NRME). NRME's John Clausen worked with the NEMO Program to create the vegetated rain gardens to receive runoff from the back half of the Center's large conference room roof. This was a research project that monitored and analyzed both the quantity and quality of roof runoff as it entered and flowed through the gardens.
The paired rain gardens were sized to contain one inch of roof runoff. Monitoring for flow and pollutants was performed by Michael Dietz and John Clausen from November 2002 through December 2004. Monitoring has ceased, but the gardens continue to be used as part of the sustainable landscape demonstration site through the NEMO program.
Results from the demo site have been published in several journals. Email Michael Dietz for copies of the following articles.
