Construction Site Stormwater Runoff Control
Uncontrolled stormwater runoff from construction sites can significantly impact rivers, lakes and estuaries. Sediment in waterbodies from construction sites can reduce the amount of sunlight reaching aquatic plants, clog fish gills, smother aquatic habitat and spawning areas, and impede navigation.
Phase II MS4s are required to develop a program to reduce pollutants in stormwater runoff to the MS4 for construction sites disturbing one or more acres. This primarily includes developing:
- An ordinance,
- Requirements to implement erosion and sediment control BMPs,
- Requirements to control other waste at the construction site,
- Procedures for reviewing construction site plans,
- Procedures to receive and consider information submitted by the public, and
- Procedures for inspections and enforcement of stormwater requirements at construction sites.
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.

A Stormwater Pollution Prevention Plan, or SWPPP, is more than simply the construction site’s sediment and erosion control plan. The SWPPP is a requirement of the Clean Water Act and State and localstormwaterregulations.
