All About Stormwater

Nutrients and Stormwater

Nutrients are targeted as the primary source of water quality impairments in the Chesapeake Bay. This training module provides the basics of nutrients, where they come from, how they cycle in the natural environment, and how stormwater management designs can reduce the discharge of nutrients to the Bay.

Impervious Cover and Stream Health

Impervious cover has long been associated with stormwater runoff and water quality.  Recent research has largely confirmed or reinforced the relationship between watershed impervious cover and stream health. This Training Module provides the background on this relationship, insight into the research, and basic strategies to help address the impacts of impervious cover. Learn more...

BMP Terminology

The Bay watershed states are all in the process of adopting new stormwater management regulations and permit requirements, creating a whole new lexicon for stormwater management practices. This training module provides a close-up look at the new design strategies and the differences, similarities, and applicability of the new stormwater BMPs. Learn more...

Runoff Reduction Theory

The Runoff Reduction theory is the basis for the process of reducing stormwater runoff from development sites using non-structural (environmental site design) practices and structural practices. This training module provides the details of the theory, the research behind the Runoff Reduction Method, and the volume reduction credits. In addition, you will find the guidance documents...Learn more...

Site Planning for Stormwater

Developing a site design with stormwater runoff in mind from the initial concept phase can provide a tremendous head start in meeting the goals of runoff reduction and the specific requirements of Environmental Site Design.
