Executive Summary: NA

Background:

The Marentette-Mangin Drain originates just north of Lambton Street and west of the Herb Gray Parkway and ultimately outlets to the Grand Marais Drain to the south. The drain, as well as the watershed that it lies within, have changed substantially over the past few decades. As development progresses, open drains become enclosed as formerly undeveloped parts of the city are urbanized. Urbanization began in the late 1980s and additional changes were caused by construction of the Rt. Hon. Herb Gray Parkway completed in 2015. The present day watershed contains a mixture of residential lands, open wooded areas and portions of the Parkway corridor. Construction of the Parkway eliminated the upstream end of the drain to the north. The remaining open drain acts as an outlet to one of the Parkway’s storm detention ponds.
