56 Boffa Miskell Ltd | Waihi North Project| Landscape and Visual Effects | N5: Black Hill in Ngatikoi Domain (VS17) Views from Ngatikoi Domain include Black Hill which rises to the south-east of GOP and observes the existing form of Gladstone Hill adjoining the Processing Plant against a backdrop of Union Hill. VS17: Black Hill This view is obtained from near the summit of Black Hill. This shows that the NRS will be visible from this area and remain an active stockpiling area during operation beyond the existing tailings storage facilities and below a more distant vegetated backdrop. Any change in view will remain in the context of the existing mining activity and surrounding rounded hills and limit any potential detrimental reduction in visual amenity. 8.5.2 Summary of Visual Effects Assessment (Northern Rock Stack) An assessment of the level and nature of visual effects from identified viewing areas associated with the Northern Rock Stack is set out below: Contributing factors Implementation52 Operation53 Residual54 Level of Effect55 Nature of Effect56 Level of Effect Nature of Effect Level of Effect Nature of Effect N1: Golden Valley Road (VS15) • Views from transport corridors and rural dwellings • Open transient views and partial fixed views of the proposed NRS and stockpiles replace existing views of rural activity in context of established mining activity • Movement of machinery and raw worked appearance may be visible Mitigation • Native planting established along the roadside and enclosing temporary grassed stockpiles will reduce available views • Reinstated in pasture at completion to assimilate within surrounding rural land use at completion Moderate Adverse Moderate - Low Adverse Low Neutral 52 Effects during implementation before mitigation 53 Effects during mitigation with mitigation 54 Long Term Residual Effects at Completion following mitigation 55 Level of Effect assessed as: Very High, High, Moderate-High, Moderate, Moderate-Low, Low, Very Low 56 Nature of Effect assessed as: Adverse, Neutral or Beneficial
