Why Manage Stormwater? 
Every resident and business in Dorchester County contributes to stormwater runoff and pollution. You may not have storm drains or flooding problems on your street, but your home or business has impervious surfaces such as a roof and driveway that increase the amount of stormwater runoff and decrease the amount of natural environment that is available to absorb stormwater. The loss of this area to impervious surfaces means that stormwater is not absorbed quickly enough into the ground by the remaining areas. The increased amount of water flows above ground until it can be collected. This water needs to go somewhere and the systems that take it away need to be maintained in order to protect property.

Stormwater management involves the maintenance and evaluation of existing drainage systems, flood prevention, water quality protection and customer service. There are direct and indirect benefits from the stormwater program.

Water Quantity (Flooding):
Over time, debris and silt can block drainage systems and drainage pipes can fail needing to be repaired or replaced, if the drainage systems that collect this water and remove it from the roadways are not maintained flooding can occur.

Development also reduces the area available for collecting the increased volumes of stormwater, hence the requirements for the use of detention pond systems in newer developments. Older developments may one day require retrofits or additional attention to reduce flooding occurrences, as they are not protected by engineered drainage systems.

Water Quality:
Stormwater is not treated before it enters the rivers, creeks, marshes and lakes (waterways) in our area. Pollution from vehicles, lawn care, yard fertilizing, pet waste and other household activities are also stormwater problems. Chemicals and other items can cause water quality problems and be harmful to aquatic life. When these chemicals, pet waste and fertilizers enter the drainage systems it can cause excess vegetation growth in ditches and ponds and affect our drinking, fishing and recreational waters. Federal Regulations, from the Clean Water Act of the 1970’s, requires the County further address and implement programs to help improve water quality in our surrounding waterways.
