Stormwater Management & Best Management Practices

This photo illustrates a variety of structural stormwater BMPs that were incorporated into a retrofit project in an urban area.  The practices shown here include rain gardens, pervious pavers, and curb cuts to divert stormwater runoff into the rain gardens.  All of these BMPs can be highly effective at managing stormwater and improving the aesthetics of commercial areas.

Land-Use Specific BMPs


Commercial development typically presents a variety of opportunities for the implementation of stormwater best management practices.  Impervious surfaces often account for a majority of the land associated with commercial areas due to large parking areas, rooftops, and sidewalks.  When developing, re-developing, or retrofitting an existing commercial area, the incorporation of structural and non-structural stormwater best management practices can greatly reduce and mitigate the impacts of stormwater.  Read below for more information and examples of successful stormwater management strategies for commercial areas.
