Project Highlights

The Town of East Gwillimbury’s stormwater drains to four (4) subwatersheds:Black River, Maskinonge River, East Holland River, and West Holland River. The Town retained Cole Engineering to prepare a Stormwater Management Master Plan as required by the Lake Simcoe Protection Plan. The study included completion of Phases 1 and 2 of a Master Plan Municipal Class Environmental Assessment (Class EA). And the Master Plan was developed in support of the current official plan with a horizon of 20 years. As a part of the study,  hydrologic modelling was undertaken to determine the impacts of development on each of the subwatersheds which are in the jurisdiction of the Lake Simcoe and Region Conservation Authority. The project included co-ordination with review agencies and consultation with the public including a public information centre. As part of this project a GIS based stormwater management (SWM) facility database was established using the SWMSoft™ Database software. The software was used to store and manage the inventory of publically owned SWM facilities. With the use of this program, a maintenance schedule was established to allow for all facilities to meet current enhanced standards. The Town was able to use this software to determine when  facilities will need to be retrofitted and an approximate cost of the work needed.
