Development Permit Landscape Plan Requirements
A landscape plan is required for the following sites:
- farm protection / ALR
- sensitive ecosystems (riparian areas, BCS corridors)
- any sites that require a landscape buffer
Developers must submit both legible, 11 x 17” hard copies and PDF versions of the plans.
All submissions and communication must go through the project’s assigned Planner. The planner will then refer it to the Landscape Architect. Do not send application material directly to the Landscape Architect.
Changes to the Landscape Plan
Due to the collection of Landscape Securities, plans always require to be developed to the construction stage for Development Permits. No changes (other than minor plant substitutions or planting configurations) can be made after the development permit has been approved.
If changes are unavoidable, all changes must be submitted to area planning, with revision clouds, for approval prior to construction. A minor or major DP amendment may be required.
Failure to get changes approved by the City prior to construction can result in added cost to the developer and lengthy delays in the release of landscape securities.

Right of Way
Plans must meet the requirements designated in each of the following categories:
- A bar scale, north arrow, site address, Surrey project number, name of the Landscape Architecture firm, the Landscape Architect that prepared the plans, a stamp, and revision date.
- Any existing or proposed road around or within the development must be shown and labelled with the street names along with existing and proposed property lines and rights-of-way.
- All existing features being retained (perimeter fences, shrub beds, etc.) must be called-up as such on the plans.
- All hard and soft landscaping.
- All surface materials and site furnishings must be called-up. Details and/or specifications are required.
- If plans are to be phased, this must be established at the DP stage
- All amenity area elements are to be included in Phase 1.
- Underground and overhead structures, such as parking or balconies, are to be identified on the plans and considered in the design. The complete boundary of underground parking plus extent of excavation is to be clearly labeled on the plans.
- A detailed planting plan and plant list.
- The plant list must include all conventional categories, including quantity, botanical name, common name, planting size / condition and spacing where applicable.
- All planting must comply with or exceed the BC Landscape Standards latest edition.
- The right plant for the right locations are to be proposed. This includes larger spreading canopies where the space permits it and appropriate species for the moisture and light levels anticipated for the location.
- A mix of small, medium, and large tree species are encouraged and creating space to support the variety will be considered during review.
- Sod is known not to survive in shady, wet locations in this region.
- Adjacent on- and off-site building height and tree canopy must be taken into consideration when proposing vegetation.
- Sun studies are required upon request if the species proposed for a location is questioned.
- Alternative shade tolerant species are promoted for shaded lawn locations. Artificial turf will not be accepted.
- A Comfort Letter for installation of soil per plan requirements at the rough grading stage may be required.
- Due to changing climatic conditions, we look for drought tolerant species and may require review of irrigation and water retention measures, particularly for roof deck gardens and planting on slab.
- A minimum topsoil volume of 10 cubic metres to a depth of 0.6 metres is required for all proposed trees.
- Planting distance requirements must be maintained:
- All measurements must include estimated mature trunk diameter as part of the distance.
- Small trees = 2m, medium trees = 3m, large trees = 4m from a foundation wall, façade, or second floor balcony.
- 1m from property lines, utilities, driveways, sidewalks, and other hardscape elements.
- 10m from skytrain structures
- 3m max ht within transmission line buffer zones
- All trees must be planted within reasonable distance to respect the mature canopy sizes of adjacent trees, including neighbouring site trees, and the impact their own mature canopy size on adjacent site features.
- Unless otherwise specified, boulevard trees are planted by the City and are not a part of the landscape contract. They should be omitted from the plans, or greyed out so that it’s clear they are not part of the landscape contract. Boulevard trees in the City Centre are an exception, and are normally shown on the plan and become part of the landscape contract.
- In multi-family residential developments, outdoor amenity areas should not overlap with retained tree protection zones (TPZs).
- No retaining walls, footings, hardscape, fire access, plantings greater than #1 size pots, furniture, play equipment, decks, patios, etc. may be placed inside the TPZ of protected trees.
- Retention of native and non-invasive understory is encouraged and may be required, particularly among clusters of retained trees.
- Surface grubbing within TPZs is not permitted.
- Western redcedar (Thuja plicata) and its cultivars (such as T. plicata ‘Excelsa’) are not to be used as hedge material.
- Parking stalls along street frontages require a planting screen with a double row of evergreen shrubs and a minimum height of 1m for at least one of the species.
- All landscape beds must have 5cm bark mulch.
- In paved areas with confined islands, structural soil is required to provide a minimum of 10 cubic metres per tree. In areas with multiple trees, a continuous trench method is preferred over isolated pits when feasible.
- Details, specifications, and a Comfort Letter from a qualified Landscape Architect or Arborist are required. See Comfort Letter Requirements below.
- Structural Soil proposals are to be coordinated with Engineering and shown on their plans for installation.
- Medium to large shade tree species with broad spreading form are required in paved areas unless otherwise noted. Small flowering or columnar form tree species will not be accepted.
- All planting over slab is required to be coordinated with the Architect.
- Minimum soil volumes must meet or exceed BC Landscape Standards and meet or exceed the following:
- Min. 1m depth for trees (unless Engineering requirements are greater to meet NCP requirements).
- Min. 0.5m depth for shrubs and ground covers/flowers (unless Engineering requirements are greater to meet NCP requirements).
- Min. 10 cubic metres per tree.
- Soil is to be recessed; mounding within planting beds will not be permitted. If minimum soil depths cannot be obtained, the roof of parking below will need to be lowered rather than mounding up.
- Minimum soil volumes must meet or exceed BC Landscape Standards and meet or exceed the following:
- Roof decks are typically extreme micro-climates for vegetation to grow in (extreme winds, sun, etc.) and are completely fabricated environments, therefore proper maintenance is required to ensure survival of the planted vegetation.
- Review of short- and long-term maintenance requirements may be required upon request. Reference may be made to BC Landscape Standards as needed.
- A band of contrasting paving (unit pavers or stamped concrete) is required at vehicular entrances (except for industrial sites with extensive truck traffic where sawcut concrete is acceptable).
- Parking stalls are to be set back so that car overhangs will not encroach within the planting beds.
- Permeable pavers are required in all visitor parking stalls in residential developments. They may be required in commercial and industrial developments depending on site drainage requirements.
- Local permeable paver types include ‘Aquapave,’ ‘SF Rima,’ and ‘PaveDrain.’ Other types may be acceptable.

- A Comfort Letter for subgrade preparation, drainage, and installation requirements per plans may be required.
- Sidewalks are to be located away from curbs to provide planting buffers.
- In cases when hardscape cannot be avoided inside the Tree Protection Zone,
- If suspended slab is proposed, complete coordination between the Arborist, Civil, and Geotechnical Engineer is required before plans may be approved.
- In cases when the maximum grading slope of 3:1 cannot be maintained, such as excavation of parking garages, etc. shoring or shotcrete solutions will have to be coordinated with the Arborist and Architect and Engineers before plans can be approved and all tree protection measure requirements must be referenced on related plans. A Comfort Letter for sidewall preparation will be required.
