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 us 847-662-2235 or use our City's  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.​

This Stormwater Management Program Plan (SMPP) was developed by the City of Park Citybased off a SMPP template provided by the Lake County Stormwater Management Commission. The purpose of the SMPP is to meet the minimum standards required by the United States Environmental Protection Agency (USEPA) under the National Pollutant Discharge Elimination System (NPDES) Phase II program. Federal regulations through the USEPA require that all Municipal Separate Storm Sewer Systems (MS4s), partially or fully in urbanized areas based on the 2000 census, obtain stormwater permits for their discharges into receiving waters. Illinois EPA has issued a new version of its MS4 Permit. The new version of the permit became effective on March 1, 2016. According to the new permit, MS4s have 180 days from the effective date of the permit to comply with any changes or new provisions contained in the permit. VIEW PLAN

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​

    Lake County Stormwater Management Ordinance

    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. .​

    ​​The Park City's Storm Water Management Regulations meet the minimum requirements of the Lake County Stormwater Management Ordinance and any project within the City's corporate limits must meet these requirements. The City of Park City's Storm Water Management Regulations is located in Chapter 15.46.010 of the Village Code. DOWNLOAD SMC ORDINANCE​​

    The most effective stormwater management programs are tailored to protect the community's assets while solving its problems and meeting its particular needs. Designing our stormwater management program to fit our specific circumstances required gathering information about existing stormwater problems and potential sources, as well as identifying natural resources, watersheds, and geographic areas that are valuable and potentially vulnerable to impacts from stormwater.

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


    Stormwater originates from rain or melting snow or other activities involving outdoor water use, such as car washing. Water that cannot soak into the ground due to impervious surfaces either flows directly into surface waterways or is channeled through storm sewers. 


    ​Stormwater runoff in urban areas must be directed through a system of pipes, ditches, catch basins and storm drains to minimize effects on private property. Because much of the stormwater system was built before stormwater codes existed and were not originally built to handle the density of houses that exist now, it is a necessity to make the most of the current stormwater system. 

    Responsibilities of City's staff include: 

    • Maintenance of the existing stormwater system.
    • Managing the stormwater effects of new construction.
    • Managing structures located within floodplains
    • Directing future stormwater improvements. 


    The City is required to comply with the     Federal Clean Water Act and the Lake County Water Shed Development Ordinance and is permitted through the National Pollutant Discharge Elimination System (NPDES).
