Schedule 'B' - Minimum Tree Survey and Tree Management Plan Requirements
Outlines the specific data and mapping requirements for tree surveys and management plans for development sites.
SCHEDULE “B”
MINIMUM TREE SURVEY AND TREE MANAGEMENT PLAN REQUIREMENTS
A. Tree Survey
The purpose of the tree survey is to accurately locate the position of the trees on or adjacent to a property to establish ownership and to accurately establish the protected root zones of all trees and tree protection requirements for tree retention during development. It provides a clear visual of where buildings and infrastructure are located and where new buildings could be best sited to minimize negative impacts to trees suitable for retention. It is also useful to show the tree protection and mitigation measures for all project phases that is recommended in an Arborist Report. The tree survey should be used as the base for the tree management plan.
The tree survey must: a) Be based on a legal survey of the lot, completed by a registered BCLS surveyor; b) Include all of the following trees: (i) All existing trees on the subject lot that can be reasonably be surveyed; (ii) All existing trees outside of the subject lot, with protected root zones or tree canopies extending onto the subject lot, or would otherwise require tree protection; and (iii) Trees identified in an accompanying Arborist Report; c) Indicate the existing trees in (b) with a scaled circle to represent the trunk and the reference ID located directly adjacent to the trunk. The canopy outline shall be indicated with a fine, dotted-line circle and the protected root zone shall be indicated with a bold, solid-line circle. d) Include a sufficient number of elevation points so that areas where cuts or fills are required can be identified on future grading plans and the tree management plan. e) Include the location and type of all existing utilities above and below grade entering or immediately adjacent to the subject site. f) Include the existing and proposed property lines, rights-of-way, easements, location of trees, base grades of trees, grades at property lines, principal and accessory building footprints, walkways, patios, retaining walls (top and toe of grade), fences, driveways, sidewalks, curbs, natural features, rock outcrops, existing services (water, storm and sanitary sewer lines, hydro, telephone, cable, internet and gas lines, and any existing service kiosks and boxes). g) Include all areas and trees protected by a restrictive covenant in favour of the City, indicating the purpose of the covenant and the land title registration number. h) Have all dimensions in metric and include a title block with north arrow, bar scale, date, surveyor’s seal and company name, and a legend to identify symbols. i) Date any revised plans.
B. Tree Management Plan
The purpose of submitting the tree management plan is to show the location of trees along with their canopy spread and protected root zones in relation to proposed changes, so potential impacts can be analyzed and trees can be identified as retained or removed. Additionally, the tree management plan is used to show where tree protection fencing, arborist supervision, ground protection or other mitigation measures are required.
The tree management plan must: a) Be prepared by a Certified Arborist; b) Be prepared with the tree survey as its basis and include the location of all trees within the tree survey; c) Show all proposed changes including preliminary lot grading (with respective slopes and elevation changes), buildings, landscaping, hardscaping, and frontage works. d) Show trees to be removed, indicated with a bold X through the survey point. The canopy outline and protected root zone shall be identified in accordance with the tree survey requirements; e) Show trees to be retained, complete with canopy outline and protected root zone identified in accordance with the tree survey requirements; f) Show any works requiring arborist supervision or tree protection recommendations, and indicate the location where they apply. g) Identify all inventoried onsite trees with unique, sequential reference ID numbers, in accordance with the arborist report; h) Date all plans and revisions.
The applicant must provide the arborist with up-to-date drawings and inform the arborist of any details for proposed changes to plans throughout the different stages of development, including but not limited to rezoning, subdivision, development permit and building permit demolition, excavation and construction.
