Storm Sewer Network Study

Phase 1 public consultation has concluded. Thank you for your participation. 

The Storm Sewer Network Study will allow Town staff to plan upgrades and enhancements to existing neighbourhood drainage systems based on the results of condition inspections, and modeling of the minor (below ground) and major (surface) flows from benchmark storm events.

The Study Area is focused on the historic urban centre within the Town of Milton. The storm infrastructure in this area is of older vintage, which predates current design standards and requirements for stormwater management to control flooding, erosion, and water quality.

The Town completed Phase 1 of the Storm Drainage Master Plan in 2020, which identified and filled any gaps in the Town’s database. This work involved completing a field assessment of the storm infrastructure in the area, to assess the physical condition and any maintenance requirements. This information has been used to establish a preliminary interpretation of storm sewer needs, and will provide key input for subsequent phases involving computer modelling and analysis, and developing an implementation plan.

The Town of Milton is now starting Phase 2 and Phase 3 of the Storm Sewer Network Study to help guide capital works, policy, guidelines and associated strategies for the management of stormwater.

The objective of Phase 2 and 3 is to:

  • Comprehensively assess the function of the existing stormwater management network
  • Document its ability to respond to continued land use changes (infill development, land redevelopment) and climate change (increasing rainfall frequency and intensity).

    CLOSED: This consultation has concluded.

    The Town of Milton is currently completing Phases 2 and 3 of the Town’s Storm Drainage Master Plan.  

    The Study is focused on the historic urban centre within the Town, which is generally bounded by Steeles Avenue to the north, Derry Road to the south, Thompson Road to the east, and Bronte Street to the west.  

    The Town completed Phase 1 of the Storm Drainage Master Plan in 2020, which identified and filled any gaps in the Town’s database, and complete a field assessment of the storm infrastructure in the area, to assess the physical condition and any maintenance requirements.  This information has been used to establish a preliminary interpretation of storm sewer needs, and will provide key input for subsequent phases involving computer modelling and analysis, and developing an implementation plan.  

    The objective of Phases 2 and 3 is to comprehensively assess the function of the existing stormwater management network and document its ability to respond to continued land use changes (infill development, land redevelopment) and climate change (increasing rainfall frequency and intensity). This study identifies system limitations that require improvements (capital projects) as well as recommendations for new/revised policies, bylaws, and/or standards to ensure that the Town’s stormwater management system continues to operate effectively for the protection of persons, property and the environment.
