Stormwater Management in the Town of Warrenton

Why do we need stormwater management?

As the landscape becomes more developed, forests and farmlands are being converted into shopping malls and housing developments. Impervious surfaces such as parking lots, roads or rooftops, cannot absorb water as the native soil and vegetation does. This causes significant increases in the volume and speed of stormwater runoff during rainstorms. 

Anyone who has impervious surfaces on their property contributes to the total amount of runoff going to the streams and tributaries. A rooftop, an asphalt driveway, or a patio can all contribute to runoff. The steady growth in this region is slowly adding impervious surfaces to the land. Between the years of 1990 and 2000, Virginia experienced a 45% increase in impervious surfaces statewide. To counteract these impacts, the Town has adopted regulations that require management of stormwater for all new development and redevelopment.

To help answer some of your stormwater management questions, the Town of Warrenton has developed some guides for homeowners as well as private owners of stormwater facilities located in the Town. Please click on the links below to view a copy of each guide.
