Stormwater Management Branch

About Stormwater: All water is not the same.  

Tap water comes from a faucet and is used for drinking, bathing, cooking, and household purposes. 
Wastewater is that which has been used, as for washing clothes or flushing the toilet. 
Stormwater originates from rain or melting snow, or other activities involving outdoor water use such as car washing. Water that does not soak into the ground due to impervious surfaces becomes run-off and either flows directly into surface waterways or is channeled into storm sewers, which eventually discharge into local water bodies.

Lakes, Ponds, and Waterways 

Orland Park includes a diverse mix of wetlands, woodlands, savannahs, streams, prairies, streams, and lakes. High quality wetlands are important natural features and can be found throughout Orland Park. Most lakes and ponds in Orland Park are man-made and designed for stormwater management as part of development projects. Lake Sedgewick, Orland Park’s largest pond, was purchased by the Village in 1989 as part of Centennial Park. Between 1998 and 2000 extensive renovations restored vegetation and opened up critical waterways. In addition to Lake Sedgewick, the Village includes 326 acres of publically owned areas of creeks, ponds and detention areas. Detention ponds collect storm water to control flooding, but also provide habitat opportunities for fish and other wildlife. Residents also enjoy the banks for fishing and hiking. The Village has approximately 185 acres of private ponds. New ponds are designed with natural edges and best management practices, but many of the Village’s older ponds need to be renovated in a more sustainable manner.

Stormwater Management  Branch

The Stormwater Management Branch is responsible for contracted mowing, broadleaf weed control, and aquatic chemical treatment of village-owned ponds and right of way sites. In addition, the maintenance of all storm lines and inlets on public easements and roadways is included. Stormwater management in this area includes best management practices, sensitive stormwater facility design and green infrastructure alternatives rather than traditional pond maintenance. The maintenance of village-owned stormwater facilities and control structures is also assigned to this branch. 

The Stormwater Branch is responsible for the implementation of the Basin Best Practices Program adopted by the Village Board of Trustees in 2011 for the management and improvement of the initial twenty-four high impact storm water facilities. This is a multi-year plan as there are over 170 Village-owned stormwater basins and properties. The goals of this program include:
  • Establish a comprehensive Village-wide approach to restoration/stewardship
  • Provide a consistent level of service and appearance to meet stakeholder expectations
  • Utilize the right resources at the right time provided by qualified staff or contractors
  • Follow industry best practices for ecological restoration and maintenance

Please visit the Basin Best Practices Program page for more information. If you have questions about the maintenance of a specific pond in the list included in that page, please contact the Parks Department at 708-403-6219.  For other ponds or wetland areas, please contact the Public Works Department at 708-403-6350.

Forms & Information

To enhance the village’s Geographical Information System (GIS), the Public Works Department has began a multi-year project to locate storm sewer structures and piping throughout the villageRead more about this project.

Information about helping the village to prevent street and backyard flooding can be found through the
Adopt-An-Inlet Program.

Call J.U.L.I.E
Remember if you are digging in your yard it is best to call J.U.L.I.E. before digging.

South Cook County Mosquito Abatement
The Stormwater Management Branch also assists the South Cook County Mosquito Abatement team in the control of the mosquito population by treating all inlets during the summer. If you have concerns or questions regarding the treatment of the mosquito population contact Mosquito Abatement at 708-333-4120.

Frequently Asked Questions

Where does Orland Park’s water go?
As shown on the Natural Resources Map, Orland Park includes seven watersheds and has six major tributary creeks which include:

  1. Long Run Creek;
  2. Marley Creek;
  3. Midlothian Creek;
  4. Mill Creek;
  5. Spring Creek; and
  6. Tinley Creek
Remarkably, Orland Park sits on a natural continental divide with Mill, Tinley, and Midlothian Creeks flowing into Lake Michigan which drains to the Atlantic Ocean, while Marley, Long Run, and Spring Creeks flow into the Des Plaines River eventually reaching the Gulf of Mexico.

What is meant by impervious?
An impervious area is any area within a parcel which prevents or significantly impedes the infiltration of stormwater into the soil. Examples of impervious surfaces include:
  • Parking lots
  • Roofs
  • Driveways
  • Patios
  • Sidewalks
  • Swimming Pools
  • Gravel and stone areas
As pervious areas (natural soil) become "paved", increased amounts of stormwater are generated, placing an increased demand on the stormwater system. 

What is the difference between the stormwater system and sanitary sewer system?
Water flowing through the sanitary sewer system is transported through collection systems and treated before it is released back into the environment.  Stormwater flows in large amounts directly into ponds and streams, streets, parking lots, etc.  It is not treated like sanitary discharge.

Why does stormwater have to be managed?
Without proper stormwater management, rain events may result in flooding on roads and properties throughout the Village, leading to property damage and dangerous road conditions. Stormwater run-off must be channeled through a system of pipes, ditches, catch basins and storm drains before being safely discharged into local streams and rivers. Even if a specific property has never flooded, the stormwater that flows from the property still contributes to the overall flow and must be managed so that it does not cause flooding downstream on property or roads.

Why should I care about stormwater?
Any property is likely to generate run-off in a severe rain storm, even if the ground is able to absorb water in a normal rain event.  Everyone in the community benefits from adequate, properly functioning drainage and flood control systems, which decrease the likelihood of flooding, erosion, and the amount of pollutants discharged in surface and stormwater run-off.  

How is stormwater regulated?
The Village stormwater system is regulated by local, county, state and federal entities. The Village is required to manage the stormwater system at a level that ensures compliance with the federal Clean Water Act and in accordance with County stormwater regulations.

What is the Village doing to address stormwater?
The Village Board has made a commitment to village residents to reduce stormwater flooding and make improvements in areas that have received flood inundation. For more information please visit Stormwater Project Updates section.
