The 2017 report by Gerard Rood, P.Eng. provided for drain repairs and improvements to the Lennon Drain including drain cleaning, bridge repairs and improvements, drain widening and the installment of flow control structures in accordance with the AECOM study and plans, and the installment of buffer strips for erosion control measures. The report included the watershed boundary for the Lennon Drain which borders the north side of the Cahill Drain – Upper Part watershed boundary.
The 1997 report by W.L. Knowles, P.Eng. provided for stormwater management in the Westbrook Estates subdivision. Additionally, the report recommended for the flattening of the drain grade from Huron Church Lone Road to the Herb Gray Parkway to allow for more additional storage.
The 1992 and 1990 reports prepared by W.L. Knowles, P.Eng. and Ken Chisholm, P.Eng., respectively provided for hydraulic modelling of the Lennon and Cahill Drain watersheds. This report gave consideration to existing developments and predicted future flows from new developments for the said drains. Recommendations were made for the entire study to control future runoff rates from new developments. The 1990 Lennon/Cahill Master Drainage Plan delineated subwatersheds for future planning of new development within the Master Drainage Plan.
The 1944 report by C.G.R. Armstrong, P.Eng. will be referenced in regards to the watershed area, and changes made to the drainage scheme due to new development. This report also included for repair and improvements to the drain based on the October 16th, 1896 report.
The 2000 report by Gerard Rood, P.Eng. aided us in determining the north watershed boundary between the Lennon Drain and Cahill Drain watersheds. The 1992 and 1990 reports supplied us with the recommended watersheds for future development. The City of Windsor provided us with plans of the storm sewers as accessible on the City of Windsor “MyWindsorSewerSystem” mapping which was used for consideration when determining the eastern and southern watershed limits as seen on our plans in Appendix “REI-E”.
As-Built plans were provided to us by the City of Windsor prepared by Aleo Associates Inc. for the Stormwater Outlet for the South Cousineau Subdivision. These plans called for the lowering of the Cahill Drain immediately downstream of the storm pipe outlet.
We arranged with the City to provide us with the updated assessment roll information for the affected parcels. We also reviewed reports for the abutting drains and spoke to the owners to help in establishing the current watershed limit for the Cahill Drain – Upper Part.
