Hydrology & Surface Water - Corktown Station

← Return to Early Works: Corktown Station

Key Findings

  • As the Corktown Station early works project footprint is located outside of the Don River Floodplain, no floodplain related impacts are anticipated.
  • Potential impacts to stormwater quality and quantity may occur and are anticipated to be minimized via implementation of appropriate mitigation measures such as minimizing the amount of exposed soil, protecting storm drain inlets and stabilizing exposed soil areas as soon as possible.

Potential Effects & Mitigation Measures

Potential Effects:

  • Potential change in stormwater quality and quantity, including erosion of exposed soil and increased sediment loading, which may impact receiving waterbodies and/or municipal stormwater drainage systems, and increased surface water/stormwater runoff.

Mitigation Measures:

  • Develop the overall stormwater quality and quantity control strategy in accordance with all relevant municipal, provincial, and federal requirements.
  • Develop a Stormwater Management Plan and an Erosion and Sediment Control Plan, as project planning progresses.
  • Consider and implement the following stormwater management best practices as required:
    • Minimize amount of exposed soil;
    • Install sediment controls before grading/land alterations begin;
    • Sequence early works activities so that soil is not exposed for long periods of time;
    • Protect storm drain inlets to filter out debris; and
    • Stabilize all exposed soil areas as soon as possible.
