Stormwater Management


Effective November 1, 2006, DeSoto County will implement a Stormwater Ordinance (PDF) as required by federal law.


Any construction site one acre or larger must obtain a Land Disturbance / Stormwater Permit from the DeSoto County Planning Department. A Stormwater Pollution Prevention Plan (SWPPP) must be submitted, approved, and implemented before site work begins. Call 662-429-8025 for more information.

Stormwater Pollution

Stormwater pollution refers to many types of harmful materials that are carried by rainwater and wash water through the storm drain system to our creeks and lakes. Ultimately this pollution reaches the Coldwater River and Arkabutla Lake because it makes its way through their tributaries. While water we use in our homes and businesses drains to a treatment plant or septic system, stormwater and anything else dumped or spilled outdoors flows into the storm drain system and directly to our waterways. Stormwater is not cleaned or treated in any way.

Stormwater pollution has many sources. One of the most common is the illicit disposal or spilling of wastes directly into storm drains, like pouring used motor oil or paint directly into a storm drain or ditch. Another common source of pollution is sediment from disturbed areas such as construction sites.

Pollutants also enter storm drains when it rains; rain runs off roofs, streets, parking lots, and other paved and impervious surfaces and flows into the nearest storm drain, picking up impurities along the way. Rain, as well as waters from hoses and sprinklers, carries detergents from car washing in addition to sediment, pesticides, herbicides, and fertilizers to the storm drain. From the storm drain, water flows directly into the nearest waterway-garbage, toxins, sediment and all.

DeSoto County's Phase II Stormwater Management Plan

In February 2003, the DeSoto County Board of Supervisors approved a Stormwater Management Plan (PDF). The plan proposes a series of activities to be performed over the next five years to improve the water quality of runoff.

Included are such things as an education program to inform members of the public and businesses of the effects of their activities, a new ordinance that will effectively prohibit the disposal of anything except stormwater into our ditches, creeks, and streams, controls on construction activities, standards for design of new developments, and a program to assure that county operations themselves are clean. There are six minimum control measures in Phase II.
