Illicit Discharge Detection and Elimination
Illicit discharges are generally any discharge into a storm drain system that is not composed entirely of stormwater. The exceptions include water from fire fighting activities and discharges from facilities already under an NPDES permit. Illicit discharges are a problem because, unlike wastewater which flows to a wastewater treatment plant, stormwater generally flows to waterways without any additional treatment. Illicit discharges often include pathogens, nutrients, surfactants, and various toxic pollutants.
Phase II MS4 entities are required to develop programs to detect and eliminate illicit discharges. This primarily includes developing:
- a storm sewer system map,
- an ordinance prohibiting illicit discharges,
- a plan to detect and address these illicit discharges, and
- an education program on the hazards associated with illicit discharges.
An effective illicit discharge program needs to be both reactive and proactive. The programs are reactive in addressing spills and other illicit discharges to the storm drain system that are found. These programs must also be proactive in preventing and eliminating illicit discharges through education, training and enforcement.
Mapping Reference Department
Keeps and perpetuates a section corner record book showing original government section corners. Checks and references yearly at least 5% of all corners shown in the record book and establishes, locates and references at least 5% of all original government section corners. This serves to create and maintain an accurate framework that all other land based government information is based on.
Manages the maintenance construction and reconstruction of all County Regulated (Legal) Drains in conjunction with the Lake County Drainage Board & Advisory Committee. Click here to find out what the Surveyor's Office is doing to coordinate area wide and county wide stormwater management efforts.
MS4 Stormwater Quality
According to U.S. EPA, polluted storm water runoff is a leading cause of impairment to the nearly 40 percent of surveyed U.S. water bodies. Click_here to find out how Lake County is combating this problem in the unincorporated areas and what you can do to help.
Geographic Information Services
It is estimated that more than eighty percent of governmental functions are associated with managing information about specific locations or geographic areas. A Geographic Information System (GIS) is a computer system for the input, editing, storage, maintenance, management, retrieval, analysis, and output of geographically referenced information. GIS supports applications such as stormwater maintenance projects, land planning, Homeland Security,law enforcement, property appraisal, civil engineering, natural resource monitoring, transportation planning, public health and environmental analysis, economic development, census analysis, and much more.
Government Center Green Roof?
As the county continues to develop as a highly urbanized society, the loss of pervious surface is an unavoidable consequence resulting in the loss of water absorption which decreases water quality and increases flooding. We propose a "green roof" for the county complex, which would be both functional and a useful demonstration project.
