Greck were retained by the developer to undertake a Flood Study to determine the regulatory floodplain extents for the subject property in support of future development endeavours in Forest Ontario. A detailed hydrologic study was completed for the 150 ha watershed of Errol Creek including all upstream municipal drains and contributing tributaries within the predominantly agricultural landscape. Resulting flows were hydraulically modelled to determine flood hazard extents within the subject property. Deliverables included a detailed Flood Study report including all hydraulic and hydrologic analysis completed as well as a regulatory floodplain map. Flood hazard mitigation options were assessed, and a detailed cut and fill balance analysis was completed in support of the proposed development and in accordance with provincial and conservation authority policies and guidelines.
