Tree Preservation Plans in Richmond Hill
Tree preservation planning in Richmond Hill is driven by the city's combination of active residential development and significant natural heritage assets. Richmond Hill is one of Canada's fastest-growing cities, with ongoing new construction in Jefferson, Westbrook, Elgin Mills and the Oak Ridges area alongside renovation and infill activity in established neighbourhoods like Bayview Hill, Mill Pond and Crosby. Every construction project that could affect a tree over 20 cm DBH requires a tree preservation plan as part of the building permit application. The lower protection threshold compared to Toronto means more trees on more properties trigger this requirement.
The Oak Ridges Moraine adds a layer of complexity that has no parallel in the municipal tree preservation planning we do elsewhere. Properties on the moraine may require a Tree Inventory and Preservation Plan that addresses not just the municipal bylaw requirements but also the Moraine Conservation Plan's vegetation policies for the relevant land-use designation. This is a provincial-level layer that operates above and beyond the City's permit process and requires the arborist report to address both simultaneously.
What a Richmond Hill Tree Preservation Plan Must Address
A Tree Inventory and Preservation Plan for a Richmond Hill development application, whether a building permit, site plan, plan of subdivision or consent under the Planning Act, must address each tree on and adjacent to the site individually. It identifies the species, DBH, structural condition and health of every protected tree, determines the Tree Protection Zone for each tree, specifies where TPZ fencing must be installed, identifies trees to be retained and protected and trees proposed for removal with justification, specifies prohibited activities within each TPZ, and establishes monitoring and reporting conditions for the construction period.
Tree Inventory and Preservation Plan Components for Richmond Hill
- Surveyed locations of all protected trees on and adjacent to the site
- Species, DBH, condition and health assessment for each tree
- Tree Protection Zone calculation for each protected tree
- TPZ fencing type, placement and installation detail
- Scaled site plan overlay showing all TPZ boundaries and construction footprint
- Tree retention or removal decision with justification for each tree
- Prohibited activities schedule within each TPZ
- Root pruning specifications where utilities or foundations must enter a TPZ
- Post-construction care and monitoring conditions
- Replanting plan for all approved removals
- Oak Ridges Moraine designation and applicable vegetation policies (northern properties)
- York Region Forest Conservation By-law notation where applicable
New Construction in Oak Ridges and Jefferson
New residential construction in Oak Ridges and Jefferson near the moraine presents the most complex tree preservation situations we handle in Richmond Hill. Properties in these areas frequently have significant native tree cover, may have woodlot areas governed by the York Region Forest Conservation By-law, and may be within the Moraine Conservation Plan's Natural Core, Natural Linkage or Countryside designations. A tree preservation plan for a new build in this area must confirm the applicable regulatory framework for each tree individually, which may differ depending on where the tree sits on the property relative to the woodlot boundary, the moraine designation boundary and the City bylaw's coverage.
We also encounter properties in these areas with trees that have ecological connections to the Oak Ridges Corridor Conservation Reserve, particularly on lots adjacent to the reserve's boundaries. The TRCA may have a role in reviewing proposed work near these edges, and the tree preservation plan should acknowledge this and provide the appropriate buffer treatment for trees near the reserve boundary.
Infill Development in Established Neighbourhoods
Infill construction in established Richmond Hill neighbourhoods like Bayview Hill, South Richvale, Crosby and Mill Pond involves different tree preservation challenges than greenfield development. The trees in these neighbourhoods are mature, protected under By-law 41-07, and often growing in proximity to adjacent property trees that are also protected. Infill lot development in Bayview Hill in particular, where large lots are sometimes subdivided for new construction, may involve trees with root systems extending across the new property boundary that must be assessed and protected during construction even though they may be on what becomes a different property after the severance.
Tree Protection Fencing Installation
We don't just prepare the plan document: we install the tree protection fencing on site. Once the preservation plan is approved and the permit is in place, we supply and install the orange construction snow fence TPZ barriers at the exact locations specified in the plan, attach the required signage to each panel, and walk the contractor through which areas are off limits for equipment access, material storage and soil stockpiling. Fencing installation is available as part of our complete plan-plus-installation package, or as a standalone service where a plan has already been prepared by another arborist and you simply need the physical barriers erected to a specific layout before construction starts.
Frequently Asked Questions About Tree Preservation Plans in Richmond Hill
Does my Richmond Hill building permit application require a tree preservation plan?
A tree preservation plan or Tree Inventory and Preservation Plan is required where the proposed construction could affect a protected tree with a DBH over 20 cm on or adjacent to the property. Given Richmond Hill's lower threshold compared to Toronto, a larger proportion of residential building permit applications trigger this requirement. We can review your site plan and confirm whether your specific project requires a preservation plan before you submit your building permit application.
How does the Oak Ridges Moraine designation affect the tree preservation plan for my Jefferson property?
The moraine designation determines the extent of vegetation removal that is permitted on the property beyond the City's standard bylaw provisions. Natural Core properties have the most restrictive policies, limiting what vegetation removal can be approved even with a City permit. Natural Linkage properties are somewhat less restrictive. Settlement Area properties are treated more like standard residential lots. We confirm the designation during the site assessment and structure the tree preservation plan to address the applicable moraine policies alongside the standard By-law 41-07 requirements.
Is arborist monitoring required during construction in Richmond Hill?
Yes, for most tree preservation plans accepted by Richmond Hill's Parks and Natural Heritage Planning section. Monitoring conditions typically require a certified arborist to inspect the site at specified construction milestones to confirm that TPZ fencing is intact, that no prohibited activities have occurred within TPZ boundaries, and that protected trees are showing no new signs of stress requiring intervention. We provide monitoring services for plans we have prepared and for plans prepared by others where the original arborist is not available.
My Richmond Hill contractor says we don't need a tree preservation plan for our addition. Should I verify this?
Yes. General contractors in Richmond Hill are often unfamiliar with By-law 41-07's tree preservation plan requirements, particularly given the lower 20 cm DBH threshold that brings many more trees into the protected category than contractors used to working in Toronto might expect. Work that proceeds without a required tree preservation plan is a bylaw violation. We can review your site plan and confirm definitively whether a plan is required before construction begins, which is a straightforward assessment that takes far less time than dealing with a compliance issue after the fact.
Do Planning Act applications in Richmond Hill require a different type of tree preservation plan?
Yes. Applications under sections 41, 51 or 53 of the Planning Act, including site plan approvals, plans of subdivision and lot consents, require a Tree Inventory and Preservation Plan prepared to the standard specified in the bylaw definition. This is a more comprehensive document than the tree preservation plan required for a standard building permit, and it becomes a condition of the planning approval rather than the building permit. Trees removed under a Planning Act condition are exempt from the standard By-law 41-07 permit requirement. We prepare both types of tree preservation plans for Richmond Hill applications and advise on which type your specific project requires.
