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.
Redmond is working on revisions to the Stormwater Technical Notebook as is required by the City's NPDES Stormwater Permit. The new changes are expected to be enforced starting January 1, 2017. Visit the updated Low Impact Development (LID) web page for more information.
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.
