The Appleby Creek Flood Mitigation Municipal Class Environmental Assessment (ACFMEA) Study was completed in February 2019. The ACFMEA study evaluated alternative solutions along Appleby Creek, from New Street to the GO Transit Rail corridor (near Appleby Go Train Station), to identify specific opportunities to reduce flooding risk and protect the natural heritage features and functions within the study corridor. The ACFMEA recommended preferred solutions for three flood-vulnerable areas within the study corridor.
For the study area north of Fairview Street (Reach 3), three options were assessed to reduce the extent of the flood hazard:
Option 1 - Do Nothing
Option 2 - Replace the existing bridge (Fairview Street) with a 17-metre span to convey the 100-year storm.
Option 3 - Replace the existing bridge with a span large enough to pass the Regional Storm
Option 2 was originally selected as the preferred alternative however, the ACFMEA File Report acknowledges that this option still results in the flooding of private property and the overtopping of Fairview Street under Regional Storm conditions. Option 2 was selected over Option 3 primarily due to the concerns of the capital cost at the time of evaluation.
Since the completion of the ACFMEA, the socio-cultural and economic environments of the study area have changed as a result of plans for land use intensification and proposed development within the vicinity of the Fairview Street crossing. As a result, the preferred solution identified in the ACFMEA for the Fairview Street crossing structure does not adequately address the flooding risks within the flood limits of adjacent development lands, specifically development lands known as Oval Court lands.
As such, the purpose of this Addendum process is to address the change of the preferred solution. The Addendum report will identify the circumstances necessitating the change to the larger hydraulic structure, and the potential environmental impacts and provide a comprehensive list of mitigative measures.
R.J. Burnside & Associates Limited (Burnside) was retained by Branthaven Development Corporation to complete an addendum to the Appleby Creek Flood Mitigation Municipal Class Environmental Assessment (ACFMEA) completed by Aquafor Beech Limited for the City of Burlington in February 2019.
A Public Open House is planned to provide information about the project and gather and respond to public comments.
