NZ Transport Agency and Tauranga City Council Mangatawa Drain Flood Bypass and TEM Stormwater AEE 10. Statutory Assessment 10.1 RMA 1991 Part II Section 5 Purpose 1. The purpose of this Act is to promote the sustainable management of natural and physical resources. 2. In this Act, “sustainable management” means managing the use, development, and protection of natural and physical resources in a way, or at a rate, which enables people and communities to provide for their social, economic, and cultural wellbeing and for their health and safety while – • Sustaining the potential of natural and physical resources (excluding minerals) to meet the reasonably foreseeable needs of future generations; and • Safeguarding the life-supporting capacity of air, water, soil and ecosystems; and • Avoiding, remedying, or mitigating any adverse effects of activities on the environment. Comment The sustainable management of the State highway physical resource has been considered alongside the potential environmental effects of the construction an operation of the highway. The proposed motorway enables the community to provide for its current and future social and economic well being, improves the health and safety of the current users of the existing SH 2 while avoiding remedying and mitigating the potential harmful effects on the life supporting capacity of air, water, soil and ecosystems. The effect of this proposed activity will also reduce the incidences of spills across the motorway providing greater route security for the State highway. It will also reduce the incidences of water entering and flooding the Maranui and Wairakei Catchments reducing the effects of surface water from the Papamoa Hills. The mitigation measures proposed reduce any potential effects to a less than minor level thereby achieving the objectives of the RMA listed above. The proposed works are in accordance with those matters listed in Section 5 of the RMA and will enhance the ability for communities to provide for their social and economic wellbeing through providing a safer and more efficient strategic transport route. Section 6 Matters of National Importance The following matters of national importance are considered relevant to the applications: Status: Final Page 95 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 (a) The preservation of the natural character of the coastal environment (including the coastal marine area), wetlands, and lakes and rivers and their margins, and the protection of them from inappropriate subdivision, use, and development: (c) The protection of areas of significant indigenous vegetation and significant habitats of indigenous fauna: (e) The relationship of maori and their culture and traditions with their ancestral lands, water sites, waahi tapu and other taonga. Comment The stormwater management system and construction management regimes will avoid, remedy and mitigate effects and thereby preserve the natural character of the downstream coastal environment. The Special Ecological Area listed in the District Plan will be continued to be protected by enlarging the treatment capabilities of the existing stormwater treatment facility thereby maintaining protection of the only significant indigenous vegetation on the project area. The proposed Mangatawa Flood Bypass will bypass the SES 13, minimising potential effects from flood discharges at this location. Archaeological and cultural protocols support the relationship of maori and their culture and traditions with the lands, water, sites, waahi tapu and other taonga. Section 7 Other Matters 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 have particular regard to— (a) Kaitiakitanga: aa) The ethic of stewardship: (b) The efficient use and development of natural and physical resources: (ba) the efficiency of the end use of energy: (c) The maintenance and enhancement of amenity values: (f) Maintenance and enhancement of the quality of the environment: (i) the effects of climate change: Comment This proposal meets the parameters of Section 7 listed above by providing for the use, development, and protection of natural and physical resources. The proposal was separated from the TEM project because of the complex way the stormwater was required to be managed in this area. Constraining elements of the proposal included the large urban areas in the Wairakei, Maranui and Arataki catchments, the infrastructural networks in Status: Final Page 96 April 2009 Project Number: 3932036 NZ1-1552092-Mangatawa Drain Flood Bypass and TEM Stormwater AEE
