Mississippi has been blessed with abundant water resources, such as beautiful creeks, streams, rivers, estuaries, bays, and coastal waters. As our state continues to grow, we face challenges to maintain clean water bodies. One of the challenges is managing storm water runoff and reducing polluted runoff.

Drainage Work on Private Property

Policy to Perform Work on Private Property [pdf]Request for Drainage Work on Private Property [pdf]

The City of Ridgeland or a private property owner may occasionally determine a need to perform drainage work in order to protect the health, safety, and welfare of its owners. The above policy was adopted to address drainage work on private property.

If you are a property owner in Ridgeland seeking assistance from the City with drainage work, you may complete the above application request. The City of Ridgeland has adopted regulations pertaining to proper stormwater management: Ordinance for Stormwater Runoff, Illicit Discharges, and Illegal Connections.

What is Stormwater?


Stormwater is rainfall or melted snow that runs off impervious surfaces, such as rooftops, streets, sidewalks, and parking lots. Impervious, or hard, surfaces prevent the storm water from naturally soaking into the ground, where the soil would filter out pollutants. As it flows, storm water picks up pollutants from these surfaces.

Common pollutants include vehicle exhaust products, brake and tire dust, oil and grease, sediment, salt fertilizers and pesticides, pet waste, and litter. Because stormwater is untreated, these pollutants enter our waterways.

Regulatory Background

In 1987, Congress amended the Clean Water Act (CWA) to require implementation, in two phases, of a comprehensive national program for addressing storm water discharges.

The first phase of the program, commonly referred to as “Phase 1” was promulgated on November 16, 1990. (55 FR 47990). Phase 1 in 40 CFR Parts 9, 122, 123, and 124 requires National Pollutant Discharge Elimination System (NPDES) permits for storm water discharge form a large number of priority sources including municipal separate storm sewer systems (MS4s) generally serving populations of 100,000 or more and several categories of industrial activity, including construction sites that disturb five or more acres of land.

The second phase, the Stormwater Phase II Final Rule, is the next step in EPA’s effort to preserve, protect, and improve the Nation’s water resources from polluted stormwater runoff. The Phase II Final Rule was published in the Federal Register on December 8, 1999 (64 FR 68722). The Phase II program expands the Phase I program by requiring additional operators of MS4s in urbanized areas and operators of small construction sites, through the use of NPDES permits, to implement programs and practices to control polluted stormwater runoff.

The Phase II Rule defines a small MS4 stormwater management program as a program comprising six elements, that, when implemented in concert, are expected to result in significant reductions of pollutants discharged into receiving bodies.

MS4 Program Elements

The six MS4 program elements, termed “minimum control measures,” include:

  • Public Education and Outreach
    • Distribute educational materials and perform outreach to inform citizens about the impacts polluted storm water runoff discharges can have on water quality
  • Public Participation/Involvement
    • Provide opportunities for citizens to participate in stormwater program development and implementation
  • Illicit Discharge Detection and Elimination
    • Develop and implement a plan to detect and eliminate illicit discharges to the storm sewer system
  • Construction Site Runoff Control
    • Develop, implement, and enforce an erosion and sediment control program for construction activities that disturb one or more acres of land
  • Post-Construction Runoff Control
    • Develop, implement, and enforce a program to address discharges of post-construction stormwater runoff from new development and redevelopment areas
  • Pollution Prevention/Good Housekeeping
    • Develop and implement a program with the goal of preventing or reducing pollutant runoff from municipal operations.
