Stormwater Technical Notebook - 2007

The Notebook describes the requirements for new development and redevelopment projects. Land developers and development engineers use the Notebook to help design site plans and determine stormwater infrastructure. Businesses use the manual to help design their stormwater pollution prevention plans. The manual is useful for anyone needing guidance on sediment and erosion control for construction sites.

This is a key document that defines stormwater requirements for development projects. It contains stormwater management goals and construction details as well as permit review processes.
