INFRASTRUCTURE CONSTRUCTORS
The Marentette Mangin Drain is considered and intermittently flowing watercourse and is not fish habitat.
Based on the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) mapping (provided in
Appendix B), the Drain is classified as a Class F drain.
It is noteworthy that the Essex Region Conservation Authority (ERCA) and OMAFRA mapping have not been updated to reflect the enclosure of the Marentette Mangin Drain at Lambton Street, or upstream of Huron Church Road. The minor and major system flows contributing to the Drain were confirmed using information from the City of Windsor Sewer Atlas sheet H12 which is provided in Appendix C.

Watershed Characterization
The Turkey Creek is under the jurisdiction of ERCA and the Ontario Ministry of Natural Resources (OMNR) Aylmer District.
Watershed characteristics for the Marentette Mangin Drain Sub-watershed were determined using information from the previous studies (discussed in Section 5.0), information obtained from ERCA’s online GIS database (refer to Appendix B for GIS mapping), topographic mapping from the AGM survey (Figure 6.1), the City of Windsor Storm Sewer Atlas (also provided in Appendix B) and field investigations.
The Marentette Mangin Drain Sub-watershed has been significantly impacted by residential deveopments both upstream and downstream of Huron Church Road. These impacts are the result of enclosure and barriers to flow, in addition to the introduction of metals, organic compounds and nutrients into the Marentette Mangin Drain. The current land uses in the Marentette Mangin Sub-watershed consist of residential developments, improved land and fragmented woodlots. The existing condition drainage area is shown in Figure 6.1.

Geology
The soil characteristics were determined based regional soil mapping obtained from OMAFRA. The soils within the vicinity of the Marentette Mangin Drain are composed primarily of Berrien Sand, which corresponds to hydrologic soil group (HSG) ‘AB.’ A weighted average curve number (CN) of 63 was calculated based on the existing land use and soil information. The distribution of soil types within the Marentette Mangin Drain study area is illustrated in Figure 6.2.
7 Description of Proposed Conditions
Several new drainage elements are proposed as part of the Windsor-Essex Parkway integrated drainage design; including a system of storm sewers, pumping stations, and stormwater management facilities. This section outlines the components of the integrated design and details are provided in later sections of this report. Refer to Figure 7.1 for proposed conditions associated with Marentette Mangin Drain.
