Why is stormwater runoff a problem?

As precipitation falls on undeveloped areas, it is primarily absorbed in the ground or slowly runs offs into streams, rivers and other water bodies with a much lower risk of picking up pollutants. Development of land resulting in more impervious surface (rooftops, driveways, parking lots, etc.) prevents water from being absorbed and creates a faster rate and amount of runoff. This development has the potential to cause flooding or water-quality issues if not properly managed.
