Proposed Plan Change 14 (PC14) – Housing and Business Choice, introduces a new requirement to provide a 20% tree canopy cover on residential development sites.
It additionally requires a 15% canopy cover to be planted in new road corridors created in greenfield or brownfield residential subdivisions. The rules, contained in the proposed new Chapter 6.10A of PC14 [PDF, 679 KB], provide an option of paying financial contributions in lieu of tree planting. The contributions will be used for off-site tree planting by the Council.
While the rules explain how to calculate the required tree canopy cover and/or financial contributions so that you can calculate these yourself, the online calculator will quickly do that for you.
More information about tree species and their projected canopy sizes can be found in section 10.9.5 of the Infrastructure Design Standard.
