Lake County needed to address the requirements of the national NPDES Stormwater Program relating to non-agricultural sources of storm water discharges. The County created and funded a Municipal Separate Storm Sewer System (MS4) water quality program with a GIS environment in mind. By utilizing GIS technology to control all of its data pertaining to the program, important issues of when, how, how much, and where water comes from and goes can be addressed. The success of the management system is now being considered for part of a legislative model, to provide a funding source for similar GIS programs across the state. Additionally, the first round of IDEM MS4 audits was so successful and organized, the Lake County Surveyor’s office was awarded the NPDES 2010 Storm Water Phase II certificate of recognition.
