    • confirmation that the fill placement can be carried out safely without causing damage to adjoining buildings or structures, utilities, infrastructure or undue settlement of neighbouring lands
    • adjoining property will not be subject to flooding as a result of fill placement

If a subsidence covenant is not already registered on the lands, provide a one page summary of the geotechnical report called “Schedule A” and attach it to the subsidence covenant to be registered on title. This summary needs to include the wording; “the subject parcel of the land may be used safely for the intended use” either residential or commercial as applicable to the specific zoning of the land.  In addition, it should make reference to the lot grading plan.
