NZ Transport Agency and Tauranga City Council Mangatawa Drain Flood Bypass and TEM Stormwater AEE 5. Site Description The purpose of this report is to assess the effects of a proposed stormwater management system for the TEM and the management of flooding across the highway. 5.1 The Locality The catchment area relevant to the project includes the Mangatawa, Wairakei and Maranui catchments as shown in Appendix 3 as drawing 3932036–CK119 Rev F. The water generally flows from the Mangatawa catchment into the harbour, or in spill situations into the Maranui and Wairakei Catchments. As shown on drawings 3932036-ck073 to 3932036-CK075 (shown in Appendix 4), the area that works will be undertaken is approximately from chainage 5250 to 10800.

NZ Transport Agency and Tauranga City Council Mangatawa Drain Flood Bypass and TEM Stormwater AEE 5.2 Land Use The subject area is located at Te Maunga within the Papamoa West Urban Coastal area. The site is approximately 5 kilometres in length, starting east of the Te Maunga intersection at Bay Park Stadium, and finishing near the Domain Road roundabout. The existing carriageway varies between 2 and 3 lanes with a 100kph speed limit. Inland and to the south west of the State highway the East Coast Main Trunk Railway line runs parallel to the road. To the north of SH2 between chainage 5250 and 8300 there is predominantly residential subdivisions then followed by rural farmland to chainage 10800. On the southern side of the road the land is rural farmland separated by the State highway and East Coast Main Trunk railway (ECMT). There is an industrial development proposed by Mangatawa Papamoa Blocks Incorporated (MPBI) on the southern side of the State highway at approximate chainage 5700 to 6850. Papamoa has increased in population by over 600% since 1981. This rapid urban, residential commercial, light industrial and educational development has highlighted stormwater and flooding problems in the area for the new residential developments. 5.3 Zoning The proposed site is within the jurisdiction of Tauranga City Council. The road itself is designated for a future four lane State Highway (part of TEM). The area to the north of SH2 is zoned Residential A from Te Maunga to approximately Bruce Road and then Rural to the Domain Road intersection. To the south from Te Maunga, the land is zoned Industrial Business and then Rural from approximately Mangatawa Lane. In the proposed project site there are several features of note from the District Plan: • The Maranui swale is designated as C116 shown with an underlying Residential A zone. However it is shown on the District planning maps as Green Belt zone. • The Special Ecological Site 13 is adjacent to proposed works about the existing TCC stormwater treatment wetland (shown in Appendix 4) • The Flood Hazard Policy Area covers much of the land south of the alignment. The increased discharge from the TCC stormwater treatment pond will discharge to the Coastal Marine Area which is administered by the Regional Council. The area is also noted as an Area of Significant Conservation Value for Banded rail, Pukeko, New Zealand kingfisher, White-faced heron and notated in the Regional Coastal plan as SSCMA-28.
