Stormwater Drainage Manual - Draft February 2010
The Greenwich Stormwater Drainage Manual establishes guidelines for the selection, design and maintenance of stormwater management and drainage facilities in the Town of Greenwich. The Department of Public Works, Engineering Division is responsible for the manual. The manual is applicable to new development and redevelopment activities undertaken by private or municipal entities, including public works projects and projects over which the Town Planning and Zoning Commission, DPW Building Division, Inland Wetlands & Watercourses Agency, Health Department, and/or other commissions have responsibility for review and approval. The manual provides guidance for developers, engineers, and local regulatory authorities to design and review projects in a technically sound and consistent manner. DPW uses the manual in its review of projects as the Town's Engineer, on behalf of Land Use agencies and other town entities.
This manual is intended to augment other existing design guidance, including the Connecticut Department of Environmental Protection Stormwater Quality Manual (as amended) and the Connecticut Department of Transportation Drainage Manual (as amended). The Greenwich Stormwater Drainage Manual is generally consistent with these state-wide manuals to ensure consistency with state stormwater management policies and to eliminate potential redundancy with other existing guidance. This manual references applicable sections of the Connecticut Stormwater Quality Manual and Department of Transportation Drainage Manual, but also includes more detailed design guidance; stronger emphasis on Low Impact Development (LID), sustainable site design, and green infrastructure; and specific stormwater management standards tailored to the unique characteristics and issues facing the Town of Greenwich.
An initial draft of the manual is available as an Adobe Acrobat File for your information. (Please note DPW is not taking public comments on this draft.)The draft will be revised with input from various Town agencies. A final document then will become available for the public comment period. During the public comment period, written comments and questions will be accepted. The public comment period will be one month and upon completion, all comments and questions will be reviewed. DPW, in conjunction with its review agencies, will then respond to comments and revise the manual as necessary to produce the final manual. DPW does expect to hold at least one public meeting on the manual; more details will be provided as progress continues. To download the Stormwater Drainage Manual click here.
