The Village manages both public and private development methodology for conveying stormwater through open channels, streams, and/or storm sewers. Typically, minor to moderate storm events are managed through the Village’s system of pipes and basins. However, extreme rainfall events can surcharge the system, leading to the use of designed surface overflow routes until the capacity of the system is restored.

Flood Information

Flood Insurance Rate Maps prepared by FEMA for Lake County, are currently used to identify flood hazard zones and determine flood insurance rates. These FEMA Flood Insurance Rate Maps, or FIRMs, are used to determine whether or not a property is subject to special building requirements.

National Pollutant Discharge Elimination System (NPDES)

Water pollution degrades surface waters making them unsafe for drinking, fishing, swimming, and other activities. As authorized by the Clean Water Act, the federal National Pollutant Discharge Elimination System (NPDES) permit program controls water pollution by regulating point sources that discharge pollutants into waters of the United States.

Similar to other communities across the region and country, the Village maintains the Village’s NDPES stormwater program permit. The Municipal Separate Storm Sewer System (MS4) Permit issued by the EPA requires that the Village monitor and regulate stormwater discharges throughout the community.

Homeowner/Homeowners Association (HOA)

Best Management Practices

Aesthetics is but one plus for properly maintained properties including single family homes and open space within a subdivision. Sustainable, watershed-friendly Best Management Practices (BMPs) are another.

Simple BMPs can be applied by the homeowner or HOA for water quality, flood reduction and healthy natural resources which adds to the quality of life factor for homeowners and those living in the watershed. What can you do? Incorporate any number of the following BMPs in and around your home:

Sustainable Living Tips For Around Your Home and Neighborhood

  1. Use a commercial car wash, or wash your car on the lawn or other unpaved surface;
  2. Sweep up yard debris rather than hosing down the storm drain;
  3. Compost or recycle yard waste when possible;
  4. Repair auto leaks;
  5. Clean paint brushes in a sink, not outdoors and properly dispose of excess paint through a household hazardous waste collection program through SWALCO or your community;
  6. Drain your pool into the sanitary sewer, not the storm sewer;
  7. Properly store hazardous waste and chemicals to prevent leaks and spills;
  8. Have your septic system inspected by a professional at least every 3 years; see Lake County Health Department for more information;
  9. Water your lawn during the cool times of the day and be careful not to over water;
  10. Before beginning a household project, located the nearest storm drains and protect them debris and other materials;
  11. After rain events, check the nearest storm drain grates for debris build up.
  12. Purchase nontoxic, biodegradable and recyclable products whenever possible;
  13. Reduce the amount of paved area and increase the amount of vegetated area in your yard and neighborhood;
  14. Use native plants in your landscaping;
  15. Use pesticides and fertilizers sparingly, and use phosphorous-free fertilizer; and
  16. Sweep up and properly dispose of construction debris like concrete and mortar.

The Clean Water Act authorizes EPA and states, which are delegated the authority by EPA, to regulate point sources that discharge pollutants into waters of the United States through the National Pollutant Discharge Elimination System (NPDES) permit program. So-called "point sources" are generated from a variety of municipal and industrial operations, including treated wastewater, process water, cooling water, and stormwater runoff from drainage systems. The NPDES Storm Water Program, in place since 1990, regulates discharges from municipal separate storm sewer systems (MS4s), construction activities, industrial activities, and those designated by EPA due to water quality impacts.
