Where We Trench in Aurora

South of Wellington you have tight Aurora Heights lots where a 24-inch bucket and a careful operator matter more than horsepower. North of Wellington — Hills of St. Andrew, Aurora Estates, North-East Aurora — half-acre and acre lots, mature trees, septic on the rural fringes, long utility runs. Bayview Wellington and Bayview Glen sit in between: newer subdivisions where trenching has to thread between irrigation heads, sod and interlock. We cover every Aurora pocket: Aurora Heights, Regency Acres, Aurora Highlands, Hills of St. Andrew, Bayview Wellington, Bayview Glen, Aurora Estates, and North-East Aurora.

Trenches We Dig

• Pool electrical and bonding trenches — sub-panel feeders, equipment bonding, light circuits. Aurora Zoning 6000-17 Section 4.12 puts pool equipment 4.5 m off the rear in Estate Residential, so feeders run longer.
• Gas line trenches — pool heater, generator, BBQ, garage heater. Cover and bedding to Enbridge spec.
• Hydro and low-voltage trenches — secondary service, garden lighting, EV chargers, detached garage feeds.
• Water service trenches — new copper or PEX from the curb stop to the house, 1.2 m frost minimum.
• Weeping tile, foundation, storm and drainage trenches — perimeter dig to footing, downspout extensions, French drains, catch basin tie-ins, sump discharge runs.

Our Process

Every Aurora trenching job follows the same sequence. Free site visit, mark the run, confirm depth and width, call Ontario One Call for public utility locates (about 5 business days). On lots with irrigation, gas to a detached structure or low-voltage, we bring in a private locator. Then we pick the machine: mini-excavator with a 12-inch or 18-inch bucket for narrow utility runs, a larger track machine for foundation perimeter and storm work. We protect lawn with plywood tracks, separate topsoil from subsoil, lay bedding sand, drop the pipe or conduit, backfill in lifts, compact, and restore.

Aurora-Specific Conditions We Plan For

Frost depth in this part of York Region runs around 1.2 m — water service and any pressurized line below that. Tree By-law 5850-16 protects private trees 20 cm DBH or larger, so we route trenches outside the critical root zone where we can and hand-dig where we can’t. The Lake Simcoe Region Conservation Authority regulates the West Holland River tributaries through north and east Aurora; jobs inside their regulated area need a permit. South Aurora drains into Don River headwaters, putting a slice under TRCA. On the rural fringes, septic clearances apply.

Equipment

Trench width and depth drive the machine. For narrow runs through tight Aurora Heights or Regency Acres side-yards, our mini-excavator in Aurora threads through 36-inch gates on a 12-inch or 18-inch bucket. For foundation perimeter on a Bayview Wellington new build, we bring a mid-size track excavator. A trencher attachment handles long shallow irrigation and low-voltage runs.

FAQ — Trenching in Aurora

Do I need a permit to trench across my Aurora property?

Not for the trench itself in most residential cases. You need permits for what goes in the trench — gas (TSSA-licensed installer), electrical (ESA permit), plumbing for water service (Town of Aurora). Site Alteration By-law 6226-19 can apply if the work moves significant fill or changes grade. LSRCA permits apply inside regulated areas near the West Holland River. We tell you which permits your job needs before we quote.

How deep do trenches need to be?

Depends on what’s in them. Pressurized water service goes below the 1.2 m frost line. Buried hydro is typically 600 mm. Gas to Enbridge spec. Low-voltage lighting and irrigation can run 200–300 mm. Foundation drains sit at footing depth — usually 2 m or more. We confirm depth before we start so the inspector signs off the first time.

Will trenching damage my lawn or interlock?

Some disruption is unavoidable but we keep it tight. We lift sod and lay it back, pull and reset interlock pavers along the trench line, and keep topsoil separate from subsoil so backfill restores cleanly. On Bayview Wellington and Bayview Glen lots with fresh landscaping, we plan for it.

Do you handle locates?

Yes. We call Ontario One Call on every Aurora trenching job — that covers public hydro, gas, telecom and municipal water/sewer. Locate clearance takes around 5 business days. For private utilities on your property — irrigation, gas to a detached garage, low-voltage — we arrange a private locator before we put a bucket in the ground.

Can you trench close to mature trees?

Yes, with care. Tree By-law 5850-16 protects private trees 20 cm DBH and up, and Town-owned trees regardless of size. We route around critical root zones and hand-dig or air-spade when we have to cross. If the route hits a protected tree, we walk you through permit options before cutting.

How long does a trenching job take?

Most residential utility trenches in Aurora are a one- or two-day job once locates clear. Foundation perimeter and drainage work runs longer — three to seven days depending on length, depth and access. We give you a date range when we quote and we keep you posted day to day.
