This document provides a description of the development process, the iSWM focus areas, and locally adopted design criteria allowing municipalities a flexible approach to apply at a local level.
The purpose of this manual is to provide design guidance and a framework for incorporating effective and environmentally sustainable stormwater management into the site development and construction processes, and to encourage a greater regional uniformity in developing plans for stormwater management systems.
Following criteria provided in the manual will help to meet sustainable development goals. There are many ways that sustainable development may be achieved while following these criteria. For example, a development that reduces individual lot imperviousness and a development that has high lot density in one area and a large open space in another can both meet sustainable requirements.
