Do existing trees count toward landscaping requirements?
Yes. Existing trees that are retained can count toward the applicable tree planting and canopy-cover requirements. Where an existing tree is relied on for canopy cover, it must meet requirements relating to tree health, protection during construction, adequate deep-soil area and suitable location.

Short Answer
Yes. Retained existing trees can count toward tree planting and canopy-cover requirements, provided they meet the applicable Technical Specifications.
Detailed Explanation
Yes. The Residential Zones Technical Specifications expressly recognise existing trees in satisfying tree planting and canopy-cover provisions. Table B provides tree-size equivalents for existing trees, while Specification 19.3 counts new and existing trees toward canopy cover. Where an existing canopy tree is retained and relied upon, Specification 19.4 requires supporting assessment by a suitably qualified person addressing its health, construction protection, deep-soil provision and suitability for retention.
