Lot Grading Permit

Lot Grading (edit).jpg ​Lot Grading is the contouring of earth to allow surface water runoff to flow away from building foundations and to follow a pre-determined drainage path.
 

  City Council passed City of Lethbridge Bylaw 5917 to provide for Lot Grading regulation, and Lot Grading Permits for new residential construction will be required effective January 1, 2013.

Lot grading is a necessary component of home construction to direct surface drainage away from building foundations to aid in preventing basement flooding.  It provides a means to control where surface drainage discharges from a property, the rate of flow entering onto public roads and minimizes the infiltration of surface water entering the sanitary sewer system.
 

Lot Grading Permit
When the decision is made to construct a new single family home, duplex, triplex or fourplex, a Lot Grading application must be submitted to Building Inspections with the Building Permit application. The applications must include a plot plan, which has been prepared by the Designer/Architect.


Plot Plan The plot plan shows a number of things including the location of the house on the property, and various elevations (or heights) of the foundation and the soil at the property lines. The plot plan demonstrates that the designer and builder are aware of the drainage pattern pre-determined for the neighbourhood prior to beginning construction.

Final Grade Certificate:  In order to ensure that the individual lots, as well as the entire subdivision are draining water properly and adequately, property grades must be verified by an Alberta Land Surveyor or Engineer, who is responsible for submission of a Final Grade Certificate to the City of Lethbridge. The Final Grade Certificate is assurance that the grades are constructed as shown on the plot plan.
