A Municipal Class Environmental Assessment (EA) is a five phase study that identifies potential positive and negative effects of municipal capital projects such as roads, water and wastewater.

The process reviews impacts on the natural and social environment, including impacts to plants and animals, traffic patterns, and to residents and businesses in the community. This process helps to stop any negative impacts that may be found during the review .

In Ontario, municipal EAs follow the Municipal Engineers Association document "Municipal Class Environmental Assessment," (October 2000, amended 2007).

Public consultation is an important part of the EA process. In Ajax we host Public Information Centres or PIC's in the community as well as consult directly with municipal councils, review agencies, interest groups, and property owners.

For more information on the process, please read the Class Environmental Assessment Process Guide.
