The overall objective is to reduce pollution of the water in and near to Winnetka. One of the most valuable resources to Winnetka is Lake Michigan, which we drink and in which we recreate.  Water shed by Winnetka as waste or storm water runoff will become increasingly scrutinized and regulated to reduce pollution and increase sustainability of the region. Given the increasing need for clean drinking water, it is important to reduce consumption and reduce pollution of the storm water. Winnetka benefits from separate sanitary and storm water sewer systems which reduces the complexity of pollution reduction. While the Metropolitan Water Reclamation District both treats the sanitary waste and regulates encroachment of the flood plain to control flooding, Winnetka may enforce more strict storm water regulations.

Coal Tar Evaluation

List of licensed pavement sealant contractors.

In April, 2014, the Village Council asked the EFC to study and make a recommendation about a potential ban on coal-tar based sealants, as a local environmental regulation that would benefit water quality.  In July, the EFC made its recommendation and on August 19, the Village Council adopted Ordinance No. MC-7-2014, which banned the use of coal tar-based sealing agents on all (public and private) driveways, parking lots and all other roadway surfaces. Other suitable sealing products are available.
