Species and types of trees shall be negotiated and agreed upon in consultation with the City Forester. Each such planting area, and "landscaping," shall be defined as an area landscaped with grass, ground cover or other landscaping material, excluding paving, in addition to the required trees. Shrubbery, hedges or other planting material may be used to complement the tree landscaping.

3.
