Vaughan Landscaping Contractor · Reformity Inc.Landscaping & Grading in Vaughan
Vaughan landscaping often starts with grade: valley-edge lots along the Humber in Kleinburg and Woodbridge, and smaller rear yards in Vellore Village and Patterson where drainage needs fixing before anything is planted. Terracing a slope means retaining walls, and the City's lot grading rules require a wall over 1 m high to be designed and certified by a Professional Engineer and set back from the nearest property line by at least its height. On most lots, two lower tiers with planting between work better than one tall wall at the fence.

A grading and landscape plan: slopes away from the house, swales, downspout outlets, protected-tree zones, walls and planting. It's what site-alteration and tree permits ask for, and it keeps water off your foundation and your neighbour's.
Landscaping permits in Vaughan
Landscape regrading on an occupied home lot doesn't need a Vaughan site alteration permit, but the City's grading criteria keep grades unchanged within 0.6 m of property lines and require any retaining wall over 1 m to be designed and certified by a Professional Engineer — Reformity prepares the grading and wall drawings and arranges any approvals needed, including TRCA on valley lots.

Vaughan Landscaping FAQ
Quick answers.
Not right up to it. The City's grading criteria don't allow grade changes within 0.6 m of a property line, so we leave that strip at its existing grade and set raised beds, patios and walls back from it. Lots backing onto the Humber or Don valleys may also need TRCA approval before regrading.
