Mangatawa Drain Flood Bypass and TEM Stormwater AEE
Comments
This assessment shows that the TEM project can treat the water generated by the alignment reducing the levels
of sediment, copper and zinc to less than existing levels.
10.6 Tauranga District Plan
4.2.2 Objective: To Sustain Natural Resources by Protecting the Functioning and Integrity of Ecosystems
4.2.2.3 Policy: Location of Activities
Use and development should avoid locating in the coastal environment where the natural character remains
intact. Activities should seek to locate where natural character has already been compromised and adverse
effects of activities can more readily be avoided, remedied or mitigated.
4.2.2.5 Policy: Indigenous Flora and Fauna
It should be recognised that intact areas of indigenous flora and fauna are underrepresented in the District,
and use and development should provide for their maintenance and enhancement.
Comments
The stormwater treatment for urban and TEM purposes require the enlargement of an existing manmade
wetland. The wetland provides the best opportunity to avoid large scale effects on ecosystems from the
operation of the TEM and urban run off. Locating the wetland elsewhere would possibly require further land
take and increase the effect of the proposal on private and public land holders. Locating the TEM treatment
facility within this site represented the best approach to minimise the effects on the SES site.
The wetland will also be replanted increasing the areas of indigenous flora and fauna on the site
4.2.3 Objective: Protecting Special Ecological Sites
To protect in their natural state and sustainably manage all significant habitats of indigenous flora and fauna
of the District.
4.2.3.2 Policy: Special Ecological Sites
Subdivision, use and development within or adjacent to sites identified in Appendix 14A: Special Ecological Site
Register or within or adjacent to other areas of significant indigenous vegetation and significant habitats of
indigenous fauna, as defined by Policy 4.2.3.3, must be carried out in a way that does not result in a reduction
in the health, viability or ecological values of those sites.
