Stormwater Management Program
What is stormwater?

Stormwater is precipitation such as rain, sleet, or melting snow. In a natural setting only a small percentage becomes surface runoff, but as development occurs this percentage increases. (Figure 1) This runoff usually flows into the nearest stream, creek, river, lake, or wetland


What is Stormwater Management?

Stormwater Management involves the control of surface water runoff. The volume and rate of runoff both substantially increase as land development occurs. Construction of impervious surfaces such as roofs,
parking lots, and roadways prevent rainfall from infiltrating into the soil.

Management of stormwater runoff is necessary to compensate for possible impacts of impervious surfaces such as decreased amount of water infiltrating the ground, increased frequency of flooding, and stream channel instability.

Why is Stormwater important?

Stormwater Management prevents physical damage to people, aquatic life and communities by preventing polluted run-off from negatively impacting waterways. The installation of impervious surfaces interrupts the natural hydrologic cycle, and causes less infiltration than was present before any development occurred. Therefore, the volume and rate of stormwater run-off greatly increases, which as a result contributes to flooding, stream channel instability, sediment, herbicides, pesticides, oils, and other pollutants getting into the storm sewer system.

Stormwater Management provides environmental benefits to local communities and reduces the amount of sediment, herbicides, pesticides, oils and debris that gets into the storm sewer system, culverts, and ditches.

Does Stormwater runoff only affect the citizens of Jackson?

No. The ditches, creeks, and streams in the City drain into rivers that flow outside of the City. The Pearl River and the Big Black River are all affected by the City of Jackson's stormwater run-off. Common pollutants, such as oil and grease from roads and parking lots, pesticides, herbicides, sediment, and carelessly discarded trash can all flow well outside of Jackson as far as the Mississippi River and the Gulf of Mexico.

Who is Responsible for Stormwater Management?


The City of Jackson has taken a socially responsible, proactive approach to systematically manage the stormwater discharged by our community. By managing runoff and preventing the pollutants from entering the storm sewer system, we are striving to avoid potential flooding and potential harm to the environment. We encourage all citizens of Jackson to join us in our efforts to protect the environment and keep Jackson beautiful.
