Local tree-rule guide
Salaberry-de-Valleyfield tree rules
Salaberry-de-Valleyfield requires authorization before removing a tree over 10 cm measured at 1 metre and couples removal with lot-tree-density, replacement and pruning rules.
The local rule
A municipal authorization is required before felling a tree with a stem diameter greater than 10 cm measured at 1 metre above ground, but that number is only the entry point: lot-tree density, replacement duties and any PIIA or project-specific review still have to be checked.
The City also maintains a minimum tree-density ratio for lots, so an approved removal can lead to replacement obligations depending on how many trees remain.
Properties subject to a PIIA or other design review can need additional analysis beyond the ordinary tree-removal certificate.
Public trees are handled by the City, and construction work must protect roots and canopy around trees being retained.
Local exceptions and conditions
The local size rule
- Salaberry-de-Valleyfield’s current tree page uses a clear 10 cm measurement at 1 metre above the ground for its felling-permit framework.
- Measure at the City’s stated height rather than substituting a different DBH convention from another municipality.
- The number identifies when the authorization system applies, but the actual decision can still depend on lot-tree density, property status and the reason for removal.
- Keep a photo of the measurement and the tree’s location with the permit file so the contractor is working on the same tree the City reviewed.
Replacement and tree density
- The City links removal with a minimum number of trees based on lot area, using a published density ratio.
- If the proposed cut leaves the lot below the required level, replacement can become part of the authorization conditions.
- Plan replacement locations before removal, especially on smaller lots where buildings, parking and utility clearances limit planting space.
- The City can use a monetary contribution mechanism in certain situations, but current fees should be confirmed directly rather than relying on an old amount.
PIIA and project-specific review
- Properties subject to a site-planning and architectural-integration program (PIIA) can require additional municipal analysis.
- A tree that appears to meet the ordinary removal criteria may therefore still be tied to a broader design or heritage review for the property.
- For construction, show the tree-protection area around retained trunks and roots; the City publishes a protection concept based on trunk diameter for work zones.
- Do not clear the site before confirming whether the PIIA, building or development approval includes specific tree-retention conditions.
Pruning and public trees
- Ordinary pruning is not an unlimited substitute for removal. The City’s guidance limits the share of branches that can generally be removed and discourages damaging cuts.
- A public tree should be reported to the City rather than treated as part of the private-land permit application.
- Where ownership is uncertain, establish the boundary before root cutting, driveway excavation or major pruning.
- The checker does not issue a hard automated verdict here because the size rule interacts with density, PIIA and ownership conditions that must be verified for the lot.
Before work starts
- Ownership: confirm whether the trunk is private, shared or on public land before authorizing work.
- Site context: check development approvals, environmental controls, easements and any prior tree-retention conditions that apply to this property.
- Work requirements: obtain the current permit, certificate, exemption or written municipal confirmation before the contractor starts.
- Keep the record: retain photos, measurements, professional reports and the municipal decision with the property file.
