Errata Sheet for the Connecticut Stormwater Quality Manual

The Connecticut Stormwater Quality Manual provides guidance on the measures necessary to protect the waters of the State of Connecticut from the adverse impacts of post-construction stormwater runoff. This manual focuses on site planning, source control, and stormwater treatment practices and is intended for use as a planning tool and design guidance document by the regulated and regulatory communities involved in stormwater quality management. 

The manual can be viewed in two ways:  The complete manual can be downloaded to your computer or you can view individual chapters on-line.  You will need the Adobe Acrobat Reader installed on your computer to view the manual files.

Stormwater Quality Worksheet (Word) (PDF)
This worksheet is to be used in conjunction with the Connecticut Stormwater Quality Manual for any new land development. It is designed to help the regulated community and regulatory agencies work through the recommendations provided in the 2004 Connecticut Stormwater Quality Manual. It is not currently required to be submitted with any permit applications submitted to the Connecticut Department of Energy and Environmental Protection (DEEP).

The individual chapters in the Stormwater Manual are available in a self-extracting zipped file.  (A self-extracting zipped file is an executable program file (.exe) that includes a zip file and software to extract or "unzip" the contents of the zip file. This feature eliminates the need of an unzipping utility such as WinZip to decompress the file.)

To download the manual to your computer, select the "Download Stormwater Manual" link below.  You will be prompted for the location on your computer where you would like to save the zipped file. Navigate to an appropriate location and select "Save".  Once the file has been saved, you should be prompted for the location to save the individual chapter files.  Note: Unless you change the location, the files will be placed in 'C:/DEP Downloads'.
