Town tree pruning starts soon in these Oakville neighbourhoods

With spring arriving in Oakville, local residents should expect to see plenty of Town workers pruning local trees.

The rotational tree maintenance program sees each of Oakville’s 108,000 street trees pruned about once a decade.

This year, the rotational tree maintenance program will include all town-owned street trees between:

  • Fourth Line and Sixteen Mile Creek from the QEW, south to Lakeshore Road
  • Neyagawa Boulevard/Fourth Line and Preserve Drive, from Dundas Street, north to Burnhamthorpe Road

“The trees in each area are inspected by certified arbourists to identify any pruning that is required. Work orders are generated for each individual tree prior to the contractor starting the work the following year,” said a Town spokesperson.

Rotational tree pruning is performed on town trees only. In some cases, town trees are located on the municipal property bordering a homeowner’s yard, which may include the house-side of the sidewalk.

Town contractors will not prune residents’ private trees as they are the homeowner’s responsibility.

Residents will receive a letter in the mail to notify them of when their town trees will be pruned. They are asked to remove lights, decorations and play equipment from the town tree in front of their home so contractors are able to access and prune the trees as necessary.

In addition, Hydro line clearing will be performed between Burloak Drive and Trafalgar Road from the QEW, north to Lower Base Line, and between Burloak Drive and Fourth Line from the QEW, south to Rebecca Street.

You can review the progress of the Hydro line clearing program on the interactive map.

The town and its contractors perform hydro line clearing on behalf of Oakville Hydro. This involves pruning trees on a four-year cycle following the Electrical Safety Authority’s (ESA) industry standard of providing a minimum three-metre clearance between branches and primary power lines and one metre for secondary lines. Crews will also prune trees to provide clearance from hydro poles and guy-lines.

Professional arbourist contractors prune trees with these goals in mind:

  • Keep the structural integrity of the tree intact
  • Maintain the health of the tree with well-placed cuts that heal well and minimize sprouting
  • Promote regrowth away from hydro lines through directional pruning
  • Leave branches growing down and away from wires to continue their growth

In some instances, the town must prune privately owned trees if they have grown too close to the hydro line.

When hydro lines are located in rear yards, Oakville Hydro has an easement through the property which allows the arborist to access the tree.

If not properly maintained, trees can create power outages or hazardous situations by touching or even falling on hydro lines. In rare instances, trees growing too close to the hydro line will be removed as a last resort if the arborist cannot meet the minimum clearance standards with acceptable pruning set out by the ESA.
