64 Boffa Miskell Ltd | Waihi North Project| Landscape and Visual Effects | During operation, parts of the proposed development will appear atypical of day to day rural activity which may normally be anticipated in the rural zone. Movement of machinery and the creation of large stockpiles of inert material will contrast with more verdant rural and pastoral areas often framed within mature trees and shelter planting. Notwithstanding this, such activity will be temporary and shift across the site as the resulting landform is gradually and permanently changed then rehabilitated to support revegetation. An initial worked appearance will remain until the final landform is completed and rehabilitated. Proposed diversion streams through TSF3 will occur during the initial stage of this development and require earthworks to create a diverted corridor which follows the contour along the eastern edge. Initially, parts of the stream diversion will appear more engineered in the context of existing stream channels which follow the floor of the gully. Many of the existing channels proposed for diversion flow through rural activity and linear drains along field boundaries. Once created, stream diversion will continue to connect SNA T13UP166 with the Ruahorehore Stream. The resultant landform modification will gradually reinforce and enhance the surrounding landcover and increasingly appear contained along a larger more vegetated, elevated, linear, and undulating backdrop. At completion, resultant embankments will be reinstated in pasture to support ongoing future rural land use and assist with the landscape’s ability to absorb further modification. In this context, any change in landscape character will become increasingly absorbed and characterised by the existing natural and working rural context. 10.3.4 Landscape Effects Assessment During operation, the interrelated landform created by TSF3 will extend mining related activity to the east of the existing form of TSF1A. Notwithstanding this, the creation of TSF3 will occur gradually rather than simultaneously and all at once. In this context, the identification of landscape effects has been considered over short term and long-term periods acknowledging such time frames will occur over different periods. An assessment of the level and nature of landscape effects associated with TSF3 are set out below: Contributing Factors Implementation67 Operation68 Residual69 Level of Effect70 Nature of Effect71 Level of Effect Nature of Effect Level of Effect Nature of Effect Landform Effects • Permanent transformation within an enclosed landform which includes the toe of an existing tailings storage facility • Proposed linear landform follows a curvilinear alignment which remains below and against more elevated areas of landform to the north Mitigation Moderate - High Adverse Moderate Adverse Moderate – Low Adverse 67 Effects during implementation before mitigation 68 Effects during operation with mitigation (5 – 10 years) 69 Residual Effects at Completion following mitigation 70 Level of Effect assessed as: Very High, High, Moderate-High, Moderate, Moderate-Low, Low, Very Low 71 Nature of Effect assessed as: Adverse, Neutral or Beneficial
