Stormwater Management

Lake County Stormwater Management

The Lake County Stormwater Management Commission (SMC) was established in 1991 through state legislation to coordinate stormwater management activities from a countywide and inter-jurisdictional perspective.

The main focus of the commission is to manage Lake County's floodplains and watersheds by administering County-wide floodplain and stormwater management standards; in addition to flood damage reduction through flood hazard mitigation projects, and implementing Best Management Practices (BMP's), watershed management plans and effective floodplain and stormwater management regulations. The commission also focuses on Natural Resource protection and restoration by utilizing a mix of funding sources and partnerships to restore and enhance the natural drainage system.

For additional information about the SMC; including special forms and applications, please visit them at their website.

Rain Gardens

A rain garden is a depressed, landscaped garden planted with native plant species that is designed to retain and infiltrate stormwater runoff from individual residential, sump pumps and roofs.

Rain gardens are versatile features that can be installed in almost any unpaved space. Rain gardens have also been used successfully in residential yards to reduce and filter roof and driveway stormwater runoff. Rain Gardens are easy to install yourself and are inexpensive.

Des Plaines River Watershed Workgroup

The Des Plaines River Watershed Workgroup (DRWW) is a voluntary, dues paying organization with a mission to bring together a diverse coalition of stakeholders to work together to improve water quality in the Des Plaines River and its tributaries in a cost effective manner to meet Illinois EPA requirements. Membership of the DRWW consists of communities, Publically Owned Treatment Works (POTWs), and other interested parties. The Workgroup consists of Agency members represented by NPDES permit holders, Associate members which are non-permit holding organizations, and individual members. The DRWW will monitor water quality in the river and tributaries, prioritize and implement water quality improvement projects, and secure grant funding to offset the cost. Monitoring data will allow for a greater understanding of the water quality impairments, identify priority restoration activities, and track water quality improvements. The Workgroup is committed to an approach for attaining water quality standards that focuses on stakeholder involvement, monitoring, and locally led decision-making based on sound science.

The Relationship between Rain Barrels and Rain Gardens

So you have a rain barrel . . . now what. Has it been installed? Does it capture all the rain from that area of your roof? Does it often overflow? If you find your rain barrel overflows often it might be beneficial to install a rain garden that will absorb the extra rainwater.

Since 2003, Rain Garden Network has been helping individuals and communities understand the importance of rain gardens, rainwater harvesting and diversion of rainwater away from streets and sewers and assisting them with the installation and maintenance of their gardens and development of their programs. We offer step-by-step instructional documentation, personal consulting, training, installation and maintenance services. See our capabilities.
