West Memorial application criteria

Criteria for processing new and existing applications

A new criteria for how planning, development and building applications will be processed in impacted northwest communities was developed to replace the case-by-case review practice. This criteria will be used to process new and existing applications until upgrades to the West Memorial Sanitary Trunk Catchment area are complete.

The new criteria:

  • Eliminates the need to delay applications with no sanitary impact caused by case-by-case review
  • Provides customers further clarity on how their project might be impacted before submitting an application
  • Enable customers to plan, develop or build to the furthest point possible before wastewater upgrades are completed
  • Delivers a consistent and transparent method of approving, holding or rejecting applications

Home Owners impact

Typically home owners only apply for development and building applications. Those applications with no sanitary sewer impacts will be reviewed as per normal City practices and are not impacted by the limitations of the West Memorial Sanitary Trunk. Examples include: residential basement renovations, decks and retaining walls, etc.

Home owners looking to replace a single family dwelling with two single family dwellings, semi-attached dwelling (two units), one duplex (two units) are also not impacted. We’ll review these applications per normal City practices.

Industry impacts

Depending on the application type, you’re planning, development or building plans could be impacted. See the new or existing application charts below for further details on how applications will be processed, and what potential options you might consider to advance your application when not approved.

Creating a timeline with industry input

We’re seeking your input to help determine the timelines for construction between permits. The goal is to match West Memorial Sanitary Trunk construction upgrades with development, to allow permits to be approved before 2017. By connecting the two timelines, development can continue in a way that it matches up with upgrade construction, helping to limit delays for our customers.

Sanitary service study guidelines

If you believe your development will not increase net flow into the sanitary sewer system, you may consider hiring a qualified professional engineer to complete a sanitary servicing study. Your study will be reviewed, and should it demonstrate no new net flow into the sanitary system, it may be approved by Water Services.

All applications are then subject to normal planning/building review process and the final decision rests with the application approving authority.
