The Engineering Services Department creates a variety of different reports on storm water management issues and activities. The Department is also involved in several organizations and committees that deal with the numerous storm water challenges the Village is facing. September 2008 Flood Report On September 13th and 14th the Village experienced a very large and damaging flood. Residents throughout the Village were affected by the flood waters from overflowing creeks, blocked drainage swales, failed sump pumps, sanitary sewer back ups and road closures. Engineering Services investigated the flooding and prepared a draft report for the more severely damaged areas of the Village. You may view this report by clicking on the following link.
Storm Water Management Program Development & Funding Study In 2005 and 2006 the Village, utilizing an engineering consulting firm, performed a study to evaluate its existing Storm Water Management Program and provide recommendations on how to comply with the new National Pollutant Discharge Elimination System (NPDES) regulations. The study also identified the costs associated with administering our Program and the different methods used to fund the Program. This study formed the basis for the Village's Storm Water Management Program that is in operation today. To view the study/program you may click on the following link. Storm Water Management Program
National Pollutant Discharge EliminationSystem (NPDES) Notice Of Intents (NOIs) The U.S. Environmental Protect Agency (EPA) requires the Carol Stream to address storm water runoff pollution through its Storm Water Management Program. The Village must do this with the use of best management practices (BMPs) through the six minimum control measures they have identified: Education, Public Involvement, Illicit Discharge Detection & Elimination, Construction Site Runoff Control, Post Construction Runoff Control and Pollution Prevention & Good Housekeeping. Starting in 2003, and continuing every five years thereafter, the Village is required to submit an NOI to the Illinois EPA that identifies the BMPs the Village will implement along with a schedule. In addition any project disturbing more than 1 acre of land must also submit an NOI. The following NOIs are available for viewing. West Street/Gundersen Drive Street Reconstruction Project Fair Oaks Road Reconstruction Project
National Pollutant Discharge Elimination System (NPDES) Annual Reports The Village is required to submit our NPDES Annual Reports to the Illinois EPA as required under our NPDES general permit. These Annual Reports document the Village's performance in meeting our schedule for implementing the BMPs we identified under the six minimum control measures in our NOI.

Total Maximum Daily Loads (TMDLs) All water bodies receive pollutants storm water runoff, atmospheric deposition, waste water treatment plants, industrial discharges, natural influences and other sources. However, when the amount of pollution reaches a certain level it adversely effects the water chemistry, natural habitat and aquatic animal life. TMDLs are limits placed on streams to protect them from receiving too much pollution. On the West Branch of the DuPage River, which Carol Stream is tributary to, the IEPA has enacted a TMDL for chloride and are study other pollutants of concern for future TMDLs including fecal coliform, dissolved oxygen, pH, silver and manganese. The Village is a member and active participant in the DuPage River/Salt Creek Workgroup (DRSCW) which is a collection of stakeholders that have been working together to reduce storm water pollution throughout DuPage County. To find more information on what Carol Stream and the DRSCW are doing to address TMDLs you may click on the following link. DuPage River/Salt Creek Workgroup
