1.0 Introduction and Intent The Town of Whitby seeks excellence in the design and implementation of landscape works that maintain and enhance the quality of life. These shall be based on high-quality urban design principles and standards that ensure new developments are safe, attractive and environmentally sensitive. Landscape works unify the variety of elements included in a new development with its environment. Landscape works integrate the built environment with the natural environment, enhance the visual character of neighbourhood streetscapes and contribute to the long-term success of new developments. The submission of a landscape plan is required in conjunction with all Site Plan and Subdivision applications in the Town of Whitby. The following are guidelines for landscape works within new and existing developments. These guidelines should be applied subject to such adjustments as may be deemed reasonable and appropriate due to the proximity of site servicing requirements, setback requirements and in accordance with the associated Subdivision and Site Plan Agreement, Letter of Undertaking, Council resolution or other such direction. The Town of Whitby seeks excellence in the design and implementation of subdivision and site plan landscaping. Proposals which exceed the minimum submission requirements are encouraged. 1.1 The intent of the guidelines are to:

• assist Developers/Applicants in the preparation of landscape plans as one of the requirements for Subdivision and/or Site Plan submissions to the Planning and Development Department

• outline requirements for the provision of landscape plan submissions in Site Plan and Subdivision development proposals in the Town of Whitby

• establish objectives and performance standards for landscape works

• ensure that landscape plans are more uniform and the approval process is more efficient

• enhance communication between Developers, consultants and the Town of Whitby

• implement excellence in landscape plans for Subdivision and Site Plan development

• encourage landscape designs that support and complement the overall design intention and aesthetic qualities of a proposed development

• encourage landscape designs that support and enhance the existing and planned context of adjacent cultural and natural landscape features

• foster a sense of civic identity and pride

• enhance proposed developments in terms of aesthetics, pedestrian safety and accessibility, and screening of operational elements of the development (stacking lanes, driveways, parking, utilities, services, garbage enclosures)

1.0 Introduction and Intent page 1


• enhance and protect existing natural features and provide new ones where possible

• promote energy conservation and efficiency (provision of sun and wind protection, etc.)

• preserve heritage landscapes of historic significance, value or interest (if applicable)

1.2 Inquiries regarding and submissions of landscape plans may be directed to: Planning and Development Department Development Control Design and Technical Services Division 575 Rossland Road East Whitby, ON L1N 2M8

Recommended Tree Species for Use in Appendix T Development Plan Proposals

Recommended Tree Species for Use in Development Plan Proposals (2016)

Town Of Whitby Tree Species List Parks, Open Spaces, Road Allowances, Edge Management/Restoration Areas, and Storm Water Management Ponds Our goal is to create and maintain a safe, healthy, diverse, and sustainable urban forest that reflects the needs of the community. Species selection is based on the following criteria:

• Hardiness Zones (5b-6a)

• Soil Chemistry

• Tree Inventory

• Experience The following is a list of recommended tree species for parks, open spaces, road allowances, edge management/restoration areas, and storm water management ponds developed by the Town of Whitby Public Works Department: Operational Services, Planning and Development Department, and Community and Marketing Services Department. This list will assist Developers in preparing landscape plans and Town of Whitby staff in tree planting services. Tree species diversity is a common measure of a community forest’s overall health. A broader diversity of tree species will guard against the possibility of large-scale devastation by both native and introduced insects and diseases. Ideally, in community neighbourhoods, tree species diversity should conform to the 10-20-30 rule of acceptable diversity proposed by Santamour (1990), whereby:

• no tree species exceeds 10% of the inventory;

• no tree genus exceeds 20% of the inventory; and

• no tree family exceeds 30% of the inventory. As a result, no monocultures are acceptable and groupings of the same species shall not exceed 8.



The use of native species is encouraged where site conditions are suitable to promote healthy growth. More information on native species is available from the Forest Gene Conservation Association, Ecodistrict 6E-13 (Oshawa-Cobourg) at www.fgca.net.

Plant material proposed for Storm Water Management Ponds shall reference the species recommendations and associated planting zones within the Ontario Ministry of the Environment (MOE) “Storm Water Management Planning and Design Manual” (current version).

Tree Specifications Trees shall be nursery grown in accordance with the Canadian Standards for Nursery Stock as published by the Canadian Nursery Landscape Association (Latest Metric Edition) and under climatic conditions similar to those in the locality of the project for the past two years.

• The recommended caliper for deciduous trees is 30mm to 60mm and the recommended height for evergreen trees is 100 cm to 200cm. Boulevard trees in new subdivision developments shall be provided at 60 mm caliper, typical. Plant material utilized for “Edge Management Areas” and “Storm Water Management Ponds” shall have a minimum 40mm caliper for deciduous trees and a minimum 120cm height for evergreen trees.

• Trees shall have one central leader. If the leader was headed, a new leader (with a live terminal bud) at least one-half the diameter of the pruning cut shall be present.

• Trees shall be structurally sound, healthy, vigorous, well-branched and densely foliated when in leaf; free of disease and insects, eggs, or larvae; and shall have healthy, well-developed root systems.

• A minimum of three structural roots reasonably distributed around the trunk (not clustered on one side) shall be present in each tree. Root distribution shall be uniform throughout the root ball, and growth shall be appropriate for the species.

• The root ball shall be sized according to the caliper of the trunk, as per industry standards. The root collar shall be visible above the soil line of the root ball.

• Root balls will be firmly wrapped with non-synthetic, biodegradable burlap and secured with heavy, non-synthetic, biodegradable twine.

This list will be reviewed annually. For additional information, please contact the Town of Whitby Public Works Department, Operational Services at (905) 668-3437 or [email protected]
