Stormwater Management  

National Pollution Discharge Elimination System (NPDES) is a permit program to control water pollution by regulating point sources that discharge pollutants into waters of the United States.

Polluted stormwater runoff is commonly transported through municipal separate storm sewer systems (MS4s), and then often discharged, untreated, into local water bodies. An MS4 is a conveyance or system of conveyances that is: 

  • owned by a state, city, town, village, or other public entity that discharges to waters of the U.S.,
  • designed or used to collect or convey stormwater (e.g., storm drains, pipes, ditches),
  • not a combined sewer, and
  • not part of a sewage treatment plant, or publicly owned treatment works (POTW).


To prevent harmful pollutants from being washed or dumped into specific types of MS4s, operators are required to obtain an NPDES permit and develop a stormwater management program plan (SMPP). The Village of Round Lake Park is an MS4 operator under the IEPA’s General Permit for Discharges.

Stormwater Management is a collaborative effort between the Department of Public Works and Village Engineer.  The Village must maintain compliance with stormwater programs as outlined by the Lake County Stormwater Management Commission and the Illinois Environmental Protection Agency.


​Stormwater is water from precipitation that flows across the ground and pavement when it rains or when snow and ice melt. The water seeps into the ground or drains into storm sewers. These are the drains you see at street corners or at low points on the sides of streets. Collectively, the draining water is called stormwater runoff and is a concern because of the pollutants it carries.

The term of the Village's General Permit from the IEPA is five years. At the end of each permit term, the Village submits a Notice of Intent to comply with the conditions of the General Permit to the IEPA. This Notice of Intent describes the practices the Village intends to implement in order to meet the conditions of the General Permit.

FEMA Floodplain Information 

The Federal Emergency Management Association (FEMA) regulates floodplain information and requirements. The FEMA floodplain maps are available for viewing at the FEMA WEBSITE. The maps can be viewed, printed or purchased on this site. It is a common occurrence for a real estate agent to confirm that a property is out of the floodplain or floodway prior to the sale of a property. 

Report Illicit Discharges/Pollution

Illicit discharges cause water pollution by sending pollutants right into creeks, streams, ponds, and lakes. Be sure you know what illicit discharges are so you can help prevent water pollution and keep our streams clean!


Prevent water pollution. Contact Village Hall at 847-546-2790 (Monday through Friday 8:00am - 5:00pm) or use our Village E-SERVICE REQUEST  to report an illicit discharge or any type of water pollution in our streams or stormwater inlets. In case of emergencies, call 911.



The Village of Round Lake Park’s Storm Water Management Regulations meet the minimum requirements of the Lake County Stormwater Management Ordinance and any project within the Village of Round Lake Park corporate limits must meet these requirements. The Village of Round Lake Park Storm Water Management Regulations are located in Chapter 157 of the Village Code. DOWNLOAD SMC ORDINANCE

An illicit discharge is an unlawful act of disposing of, dumping, spilling, emitting, or other discharge of any substance other than stormwater into the stormwater drainage system. The stormwater drainage system includes streets, ditches, catch basins, yard inlets, lakes, and streams.

Below are some examples of illicit discharges:

  • Paint being poured into or near the storm drainage system
  • Changing oil or antifreeze over or near a storm structure
  • Washing vehicles where the runoff could drain into the storm drainage system
  • Washing dumpster pads and allowing the runoff to drain into the storm drainage system
