Site Preparation in King City and the Township of King

OCM Excavation & Construction handles site preparation across King City, Nobleton, Schomberg, Kettleby and the rural concessions of the Township of King. Site prep is everything that has to happen before a foundation crew shows up — clearing trees and brush, demolishing the old house or barn, stripping and stockpiling topsoil, rough grading, and getting erosion controls and hoarding in place. We have worked on estate-lot teardowns, equestrian property conversions and infill builds throughout King since 2008. For a site walk and quote, call 416-317-3090.

Why site preparation in King City is different

King City sits on the Oak Ridges Moraine. The moraine is the aquifer recharge zone for a chunk of the GTA, and the Oak Ridges Moraine Conservation Plan tightly controls what you can do with topsoil, vegetation, fill and impervious surfaces. Stripping topsoil for storage, importing fill or grading toward a swale can all trigger review under the Township of King Site Alteration By-law 2021-039 — and on ORM-designated land, the standard you have to meet is higher than on a typical suburban lot.

Layer the Greenbelt Plan on top of that and a piece of King property can carry two or three overlapping planning regimes. The Heritage Conservation Districts in the King City core and the Schomberg core add another set of rules — exterior demolition and major site changes within a HCD need a heritage permit, even if the building itself is not listed.

Then there is the property itself. A King City lot is rarely 40 by 120. We are usually working on one to five acres, sometimes more. That means more trees, more vegetation, more outbuildings, and a real chance of an old well and septic system that need to be properly decommissioned. Equestrian conversions add their own list — paddock fencing, run-in sheds, manure pads, riding rings — that all has to come down, get hauled and get accounted for. Agricultural-to-residential transitions can also surface old fuel tanks, drive sheds and farm dumps that nobody mentioned during the listing.

Site preparation services we provide in King City

• Site clearing — tree and brush removal, hedgerow clearing, removal of agricultural structures and fencing.

• Rough grading — establishing pad elevations, drainage flow and lot-line setbacks ahead of foundation.
• Erosion and sediment control — silt fence, mud mats, rock-check dams, catch-basin protection.
• Temporary fencing and hoarding — site fencing, tree-protection hoarding around trees being retained, neighbour-side protection.
• Well and septic decommissioning — proper abandonment of old wells and tanks per provincial requirements.
• Dust and access control — water trucking on dry days, gravel access roads off the township road.

If you are looking for the broader regional picture, our site preparation services across the GTA page covers the equipment list and the typical scope by lot size.

Our site prep process in the Township of King

1. Pre-survey and topo — we coordinate with an OLS to get a current topographic survey if you do not already have one. On rural King lots a stale survey is a real risk.
2. ORM and Greenbelt pre-check — confirm which overlays apply to the property and what that means for clearing, stripping and grading.
3. Permits — demolition permit through the Township, Site Alteration permit under By-law 2021-039 if grades or fill trigger it, conservation authority approval (TRCA in south King, LSRCA in north King), and Heritage District approval if the property is in the King City or Schomberg core.
4. Locates and utilities — Ontario One Call for buried services, plus private locates for septic tanks, weeping beds and abandoned wells.
5. Clearing and demolition — staged so material can be sorted and hauled efficiently, with concrete and clean fill separated where possible.
6. Strip, stockpile, rough grade — topsoil pulled and stockpiled in a controlled location, subgrade rough-graded to building department expectations.
7. Erosion control and turnover — silt fence and access controls left in place for the next trade.

The same crew that does the site prep usually handles the foundation excavation that follows. Our King City excavation page covers the foundation side, and our land grading and yard preparation page covers the finish-grade work that comes much later.

What affects site prep cost in King City

• Acreage — a one-acre infill is very different from a five-acre equestrian property. Scale changes everything from haul counts to silt-fence linear footage.
• Vegetation and tree count — King Township does not regulate single private trees by DBH the way Toronto or Vaughan do, but woodland tree removal is regulated by the Region of York under the Regional Forest Conservation By-law, and heritage trees in HCDs need their own consideration.
• Demolition complexity — older homes can hide asbestos in vermiculite, plaster, pipe wrap and floor tile. A designated substance survey is normal due diligence before demo on anything pre-1990.
• Old well and septic systems — decommissioning a drilled well and pulling a 1970s steel tank with a leach bed adds time and cost, but it has to be done right.
• Equestrian and agricultural structures — manure pads, run-in shelters, riding-ring footing, paddock fencing, hay barns and drive sheds all have different demolition profiles.
• ORM, Greenbelt and Heritage District involvement — added approval time and added constraints on how the work is staged.
• Hauling distance — King is rural. Travel to the nearest fill-receiving site can be longer than in the suburbs further south.

We price site prep after a walk-through. There is no honest way to quote a King estate-lot teardown from a Google Street View screenshot. To book a site walk, call OCM at 416-317-3090.

Frequently asked questions

Do I need a Site Alteration permit for site prep in King Township?

If your work changes grades, moves fill onto or off the property, or strips topsoil beyond a minor area, Township of King Site Alteration By-law 2021-039 generally applies. On Oak Ridges Moraine and Greenbelt land, the threshold for needing a permit is lower and the conditions are tighter. We confirm with the Township before we start moving dirt.

Do I need a tree permit to clear trees on my King City lot?

King Township does not have a private-property tree by-law that protects single trees by trunk diameter the way Toronto, Vaughan and Markham do. However, woodland tree removal is regulated by the Region of York under the Regional Forest Conservation By-law, and removal inside a Heritage Conservation District or on ORM-designated land may need additional approval. We check before any chainsaws start.

We have an old well and septic on the property — can you handle decommissioning?

Yes. Drilled wells need to be properly abandoned per provincial requirements, and old septic tanks need to be pumped, crushed and removed or filled in place. We coordinate this as part of the site prep so the new build is not sitting over an undocumented tank.

How long does site prep take on a King City estate lot?

It depends on what is coming down and how big the lot is. A straight house demolition with light clearing on a one-acre lot can be a couple of weeks of active site work. A full estate-lot prep with equestrian structures, mature vegetation, a pool and an old septic system can run several weeks plus the time required for permits and conservation authority sign-off.
