NZ Transport Agency and Tauranga City Council Mangatawa Drain Flood Bypass and TEM Stormwater AEE the project area and the nearby Marae of Nga Potiki. NZTA has undertaken a lengthy and thorough consultation process during the project history. The stewardship ethic and an understanding of Kaitiakitanga are present in the project through NZTA’s own organisational values and in its consultation with hapu affected by the proposal. This is seen in restriction of works in the Lower Mangatawa Drain to help to protect the whitebait and eel fisheries identified by Nga Potiki and other users of the waterway as important. In this area there is also opportunity for restoration of the lower Mangatawa Drain and the opportunity for newly created recreational areas adjacent to the drain increase the potential amenity of the area. The stormwater treatment design and mitigation provisions reduce the contaminants entering the water way and highlight NZTA’s desire to maintain and enhance the quality of the environment. Furthermore, in providing for an easy free-flowing motorway access from Paengaroa to the Port of Tauranga and surrounding environs, there will be more efficient use of energy used in transportation and reduced greenhouse gas emissions in comparison to the current State highway. Section 8 Treaty of Waitangi Section 8 states that: In achieving the purpose of this Act, all persons exercising functions and powers under it, in relation to managing the use, development, and protection of natural and physical resources, shall take into account the Principals of the Treaty of Waitangi (Te Tiriti o Waitangi). Comment The process of consultation undertaken by NZTA has been extensive and inclusive. Not only in the current resource consent processes but in the original Designation process the project has been discussed with representatives from Iwi and hapu from the area. The NZTA has attempted to undertake a partnership approach to the Project and has facilitated the creation of the TEM TWAG as a forum for the resolution of construction issues. District Council – Land Use Consent Section 104D Particular restrictions for non-complying activities This section quoted below relates to the consideration of the district land use consent for earthworks adjacent to the SES13. (1) Despite any decision made for the purpose of section 93 in relation to minor effects, a consent authority may grant a resource consent for a non-complying activity only if it is satisfied that either— (a) the adverse effects of the activity on the environment (other than any effect to which section 104(3)(b) applies) will be minor; or (b) the application is for an activity that will not be contrary to the objectives and policies of— (i) the relevant plan, if there is a plan but no proposed plan in respect of the activity; or Status: Final Page 97 April 2009 Project Number: 3932036 NZ1-1552092-Mangatawa Drain Flood Bypass and TEM Stormwater AEE
NZ Transport Agency and Tauranga City Council Mangatawa Drain Flood Bypass and TEM Stormwater AEE (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 10.2 Bay of Plenty Regional Policy Statement (RPS) These resource consent applications for earthworks, water take, structures and stormwater discharge do not challenge the intent the objectives and policies listed in the RPS, in particular: Maori Culture and Traditions -Objective 5.3.2(a): Recognition of and provision for the relationship of Maori and their culture and traditions with their ancestral lands, water, sites, waahi tapu, and other taonga.
