This section is subject to the following plan change- Proposed Plan Change 6- Regulatory Efficiency and Effectiveness Plan Chang​e​

25.5.4.1 All Fences and Walls

a)Any fence or wall adjoining a buffer strip or planting strip required by this plan which is adjacent to a transport corridor or other public space shall be either: ​
​i.​located so that the buffer or planting strip is between ​​the fence and the external site boundary, and shall be designed to enable access to plantings for maintenance purposes; or
​ii.​Be permeable in accordance with Rule 25.5.4.2 below.

25.5.4.2 Permeable Fences

a)​The following design and dimensions shall apply to permeable fences. ​
Design requirements
i. Materials with 50% or more see-through visibility in a consistent manner along the entire length of the fence, or
 
ii. Materials with 50% or more see-through visibility6m (Ruakura Logistics Zone only, see Rule 25.5.3.1k) 

Note

1. Refer to Figure 25.5.4a for examples of acceptable and unacceptable fencing solutions.

25.5.4.3 Buffer Strips

a)Buffer strips shall ​be of a permeable nature for stormwater purposes.​
b)​Buffer strips shall consist of shrub or hedge planting (hedges are recommended where buffer strip widths are less than 2m) selected and maintained in a manner to ensure a mature height of at least 1.8m and shall be at least 0.5m in height at the time of planting.​
c)​Shrub or hedge planting shall be selected, located, provided at a density, and maintained in a manner to ensure that, when mature, a visually impermeable screen of planting is achieved (refer Figure 25.5.4b): ​
i.​Along the length of the buffer strip, and ​
ii.​To a height of at least 1.8m.​
d)​Buffer strips shall include specimen trees at the following minimum rates:
Length of the buffer strip​Number of specimen trees​
Up to 10m​1​
For each additional 10m or part thereof​An additional 1​
 Except where frangible vegetation is required by Rule 25.5.3.4, in which case frangible trees shall be required instead of specimen trees.​
e)​Trees required by 25.5.4.3(d) shall be selected to ensure they are capable of growing to a mature height of more than 4m and shall be at least 1.8m in height at the time of planting.​
f)​Where two or more trees are required by 25.5.4.3d) they shall be spaced along the length of the buffer strip to ensure they are no more than 15m or less than 5m apart (refer Figure 25.5.4c).​

25.5.4.4 Planting Strips

a)Planting strips shall be of a permeable nature for stormwater purposes.
b)​Plant​ing strips shall consist of a combination of groundcover and shrub planting, with shrub planting selected to ensure they are capable of achieving a maximum mature height of 0.8m, and are least 0.4m in height at the time of planting.
c)​Groundcover and shrub planting shall be maintained to ensure they do not exceed a height of 0.8m (refer Figure 25.5.4d).
d)​Groundcover and shrub planting shall be selected, located and provided at a density to ensure that a minimum of 50% of the surface of the planting strip is covered from the time of planting.​
e)​Planting strips shall include specimen trees at the following minimum rates.
Length of the planting stripNumber of specimen trees​
Up to 10m​1​
For each additional 10m or part thereof​An additional 1​
Except where frangible vegetation is required by Rule 25.5.3.4, in which case frangible trees shall be required instead of specimen trees.​
f)​Trees required by 25.5.4.4e) shall be selected to ensure they are capable of growing to a mature height of more than 4m and shall be at least 1.8m in height at the time of planting.
g)​Where two or more trees are required by 25.5.4.4e) they shall be spaced along the length of the strip to ensure they are no more than 15m, or less than 5m apart (refer Figure 25.5.4c).
h)​All trees shall be maintained to ensure that a clear distance of 2m is achieved between ground level and the tree canopy (refer Figure 25.5.4d). This standard shall not apply until a specimen tree reaches at least 4m high.​
i)​Trees within the planting strip shall be selected, located and maintained in a manner so as not to:​
i.​Create traffic safety problems by obscuring visibility for road users or train drivers.​
ii.​Obstruct traffic, official road, or hazard signage.​
iii.​Interfere with transport infrastructure or network utilities.​

25.5.4.5 Planting Area

​a)Where a planting area is required, the area shall:​
i.​Be of a perm​​eable nature for stormwater purposes.​
ii.​Consist of a combination of groundcovers and shrubs or hedges.​
iii.​Include specimen trees at the following minimum rates:
Length of front boundaryNumber of specimen trees​
Up to 10m​1​
For each additional 10m or part thereof​An additional 1​
iv.​Be located in the front setback between the non-residential activity and the adjoining transport corridor boundary.​
v.​Include groundcover, shrub or hedge planting that has been selected, located and provided at a density to ensure that a minimum of 30% of the area of the front setback requirement of the relevant zone is covered from the time of planting.​

25.5.4.6 Internal Planting

a)Inte​​rnal planting ​shall be located within the sealed area to break up the impermeable expanse of paving and hard surfaces while ensuring pedestrian and vehicle safety. For large areas this will require the internal planting requirements to be split into more than one location.
b)Internal planting shall consist of a combination of groundcovers and shrubs.
c)Internal planting shall include specimen trees at the following minimum rates:
Number of parking spacesNumber of specimen trees​
Up to 201
For each additional 10​ spaces or part thereof​An additional 1​​
d)​Groundcover and shrub planting shall be selected, located and provided at a density to ensure that a minimum of 50% of the surface of the internal planting area is covered from the time of planting (refer Figure 25.5.4e).
e)​Shrub planting shall be selected to ensure it is capable of growing to a mature height of at least 0.5m and shall be at least 0.3m in height at the time of planting.
f)​Trees required by 25.5.4.6c) shall be selected to ensure they are capable of growing to a mature height of more than 4m and shall be at least 1.8m in height at the time of planting.
g)​ Trees shall be located within a planting space free from impermeable surfaces with a minimum dimension or diameter of 1.5m diameter.
h)All planting shall be protected from potential pedestrian and vehicle damage.

Note
1. Suitable means of compliance includes providing formalised pedestrian crossing points, ensuring plant selection and layout does not make crossing difficult, low fencing, or wheel stops (refer Figure 25.5.4f).
2.  For larger external ground-level parking spaces in all zones (more than 20 parking spaces) any assessment of landscaping proposals should consider the total site area including landscaping and trees to be planted within planting and/or buffer strips.
