Land Grading in Newmarket — Yard, Driveway, Lot

We handle land grading in Newmarket for homeowners, builders, and small commercial sites — yards that hold water after every storm, driveways that pitch back toward the garage, and new-build lots that need a stamped lot grading certificate before occupancy. OCM Excavation & Construction runs the laser, the skid steer, and the dump trailer on the same crew. Call 416-317-3090 for a free site visit anywhere from Historic Downtown to Stonehaven, Glenway, and Woodland Hill.

What Land Grading Actually Means on a Newmarket Lot

Grading is the shape of your dirt — the slopes, swales, and elevations that move water away from the house and toward the street, the rear yard catch basin, or the municipal easement. In Newmarket, the Town wants positive drainage away from the foundation at roughly 2% minimum for the first 1.8 m, then a controlled fall across the rest of the lot to the approved discharge point shown on your grading plan.

When grading goes wrong, you see it fast: ice sheets on the driveway, soggy lawn patches for weeks after a thaw, basement seepage along the cold-joint, mulch washing out of the front beds, interlock shifting because the base is sitting in water. We fix all of it.

Lot Grading Certificates for New Builds & Major Renos

If you’re finishing a custom home, a major addition, or a substantial reno in Newmarket, the Town typically requires a final lot grading certificate sealed by an Ontario Land Surveyor (OLS) or a Professional Engineer (P.Eng.) before they’ll close out the permit and release deposits. We don’t stamp the certificate — that’s the surveyor’s signature — but we build the grade to the approved plan so the certifier shows up, shoots the elevations, and signs the same day.

Our crews work directly from the engineered grading plan, hit the spot elevations within tolerance, cut the swales to spec, and protect the rear-yard discharge so nothing has to be redone. If you’ve already had a certifier flag a “fail” letter, call 416-317-3090 — we re-shape the lot and get you back to a pass.

Yard, Driveway, and Drainage Grading We Do in Newmarket

• Backyard re-grading — strip the sod, re-shape the subgrade, install a swale or French drain, top with fresh screened topsoil and sod or seed.
• Driveway pitch correction — common on older Davis Drive corridor homes where settlement has pitched the slab back toward the garage. We excavate, rebuild the granular base, and re-pitch before paving or interlock.
• Side-yard swales — the 0.6 m to 1.5 m strips between houses are where most Newmarket drainage failures live. We cut a proper swale and tie it into the front or rear discharge.
• Rear-lot catch basin tie-ins — where the grading plan calls for a CB, we set it, gravel-pack it, and confirm the invert matches the storm lateral.
• Foundation re-grading — pull the soil back off the brick, slope away at 2% minimum, install drainage membrane if the wall is exposed during the work.
• New-build rough & final grade — from raw lot to certifier-ready in one crew.

Newmarket-Specific Things We Watch For

Newmarket sits in the Lake Simcoe watershed, which means anything close to the East Holland River corridor falls under LSRCA (Lake Simcoe Region Conservation Authority) review under Ontario Regulation 41/24 — not TRCA. If your lot is within the regulated area, we coordinate the LSRCA permit before we touch dirt. LSRCA’s office is reachable at 905-895-1281.

Trees are the other one. Newmarket’s Private Tree Protection By-law requires a permit to remove any private-property tree larger than 20 cm DBH (diameter at 1.4 m above ground). If a tree near the work zone is going to be impacted by the grade change, we tell you up front so you can pull the permit — or so we can adjust the grade to protect the root zone. Removing first and asking later gets expensive.

Typical Newmarket Land Grading Costs

Pricing depends on yard size, how much soil moves, whether sod and topsoil are included, and whether a stamped certificate is part of the scope. As a rough order of magnitude for Newmarket residential properties:

• Small backyard re-grade with new sod — generally a few-thousand-dollar range.
• Full lot re-grade with swales and tie-ins — typically mid four to low five figures.
• New-build rough-to-final grading on a standard Newmarket subdivision lot — quoted on the engineered plan.

Why Newmarket Homeowners Call OCM

We’re an excavation-first contractor — grading is what we do every day, not a side-line we tack onto landscaping. Our crews run laser levels, not eyeball-and-rake. We coordinate with your surveyor or engineer when a certificate is needed, we pull LSRCA permits when the lot demands it, and we leave the site clean.

Frequently Asked Questions

Do I need a permit to re-grade my Newmarket backyard?

For most residential re-grading inside the existing lot footprint, no Town permit is needed. The exceptions are work inside an LSRCA-regulated area near the East Holland River, work that affects a regulated tree over 20 cm DBH, or work that changes drainage onto a neighbouring property. We flag any of those during the site visit.

Who issues the lot grading certificate?

An Ontario Land Surveyor (OLS) or a Professional Engineer (P.Eng.) — not the contractor. We build the grade to the approved plan and the certifier shoots final elevations and seals the document. If you don’t have a surveyor lined up, we can point you to ones we’ve worked with in Newmarket.

How long does a typical Newmarket re-grade take?

A small backyard re-grade with sod is usually 2 to 4 working days. A full lot with swales, drainage tie-ins, and sod runs about a week. New-build rough-to-final grading depends on weather and the certifier’s schedule — we sequence it around the framing and siding milestones.

Will you damage my existing lawn, fence, or interlock?

We protect what stays. Mature trees get root-zone protection, fences come off only where access requires it and go back on the same alignment, interlock that has to lift gets palletized, screened, and reset. Anything we have to remove is identified in writing before we start.

My neighbour’s water drains onto my lot — can grading fix that?

Often yes. A properly cut swale along the property line and a tie-in to the front or rear discharge point can intercept the runoff. Where the issue is more severe, we may recommend a French drain or a sump-pumped catch basin. We don’t re-direct water onto someone else’s property — that creates a new problem and a Town complaint.

Do you work in winter in Newmarket?

Grading dirt that’s frozen solid is not productive. We can do emergency drainage work in shoulder seasons, but full re-grades are best booked between April and late November in Newmarket. Get on the schedule early — spring books out fast.
