(ii) the relevant proposed plan, if there is a proposed plan but no relevant plan in respect of the
activity; or
(iii) both the relevant plan and the relevant proposed plan, if there is both a plan and a proposed plan
in respect of the activity.
(2) To avoid doubt, section 104(2) applies to the determination of an application for a non-complying activity.
Comment
In relation to the District Plan the non complying element of the proposal relates to the earthworks and
removal of vegetation required by the redesign of the stormwater treatment wetland. The wetland needs to be
redesigned to accommodate stormwater generated from the TEM, the future developed Maranui residential
area, the proposed Truman Lane industrial area and some of the Arataki catchment. This will require
earthworks significantly greater than the threshold set adjacent to the SES.
These activities will provide better environmental outcomes for the SES by improving water quality in the
Harbour and reducing the potential for sediment to enter the Harbour.
To reduce the likelihood of effects on the SES, the earthworks activity will be undertaken in accordance with
the example Erosion and Sediment Control Plan that is submitted as part of this consent. The plan provides
guidelines and environmental criteria that the contractor will be required to meet to mitigate the potential
effects of this activity to a less than minor level. Compliance with these guidelines will be embedded in the
contracting documents being the Principals Requirements.
Removal of vegetation in the Stormwater Treatment Wetland is required to redesign the pond to achieve the
ARC TP10 treatment level for stormwater. The design however has retained existing vegetation as much as
practicable but some removal is expected. The wetland will be re-vegetated with appropriate species to
mitigate some of the lost vegetation. Given the temporary nature of this loss and NZTA’s and TCC’s
undertaking to restore where possible, the effects of this activity are considered to be less than minor.
Commentary on the objectives and policies of the district plan regarding the non complying activity is detailed
in section 10.6
