PROJECT: Saltfleet Conservation Area Wetland Design (SC-8)

CLIENT: Hamilton Region Conservation Authority

DESCRIPTION OF PROJECT:

• Water’s Edge team was engaged by the Hamilton Conservation Area (HCA) to complete necessary studies and prepare a Preliminary Design for the SC-8 water retention facility, wetland and creek restoration within the Upper Battlefield Creek watershed.
• As part of the Saltfleet Conservation Area Wetland Restoration Program, the area of investigation will be designed to create a wetland for storage of stormwater to reduce peak flows of the upper Stoney Creek for flood and erosion control.
• The existing road grade will be raised by 0.5 m (from the current elevation of 193.5 m) and new earth berms will be created to approximately 194.0. The basin of the proposed wetland will be at EI. 192.0 m.
• The contributing drainage of the SC-8 site is predominantly agricultural, with some residential areas in the southwest portion of the contributing area.
• The existing channel within the SC-8 site and the downstream receiving reach have been historically aligned to maximize the useful agricultural land but lead to faster conveyance and higher downstream flood risks.
• Terrestrial and aquatic field surveys were undertaken within the subject property to characterize natural features and identify significant and sensitive features and species that have potential to be adversely affected by the proposed development.
• A comprehensive field program was developed in consultation with HCA staff.
• Authorization to proceed with the study was received in June 2019.
