Commercial Lot Grading Plan Approval

A Lot Grading Plan has been a part of the approval process all non-residential (commercial, industrial, institutional) developments, large-scale residential developments (apartments, row houses and other residential developments with multiple buildings), mixed-use (a mix of residential and non-residential) developments, and temporary structures such as storage sheds and sea cans since 1993. The plan is required for new developments and approved by the City of Edmonton, Development Services on behalf of the City Manager.

This plan specifies design elevations, surface gradients, swale locations, and other drainage information required for lot grading. The approval of this plan provides an effective basis for lot grading control which will establish the drainage relationship between adjacent properties.

The example drawings of Lot Grading Plans for multi-unit residential, typical commercial, and shopping centre developments provide general information of what should be shown on the plan (for reference only).

Application

Upon application for a development permit, the owner/developer must submit a Lot Grading Plan, a Site Mechanical Plan, and stormwater management (SWM) calculations to EPCOR Water Services Inc. Infill Water and Sewer Servicing.

This plan must be reviewed and approved by EPCOR Water Services Inc. and the City of Edmonton Development Services, Lot Grading, before the construction of any buildings, additions to buildings, or alterations of surface drainage.

It is the owner’s/developer’s responsibility to make a request to EPCOR for the installation of new water and/or sewer services, or modification of existing services at the owner’s expense. EPCOR is responsible for the construction of the services from the EPCOR mains to the property line only.

The owner/developer is responsible for all works on private property. Only EPCOR crews are allowed to perform work within utility right-of-ways and construct services from the mains to the property line.
