Boffa Miskell Ltd | Waihi North Project | Landscape and Visual Effects | 47 7.5.2 Summary of Visual Effects Assessment (Gladstone Open Pit) An assessment of the level and nature of visual effects from identified viewing areas associated with GOP are set out below. For the purpose of this assessment mining activity represents “implementation” which is expected to occur over a period of approximately 7 years followed by the establishment of a subsequent tailings facility (operation) and closure (residual) effects: Contributing factors Implementation41 Operation42 Residual43 Level of Effect44 Nature of Effect45 Level of Effect Nature of Effect Level of Effect Nature of Effect G1: Clarke Street / Heath Road (VS11 and VS12) • Possible views from up to seven dwellings and recreation areas adjacent to the Ohinemuri River • Views predominantly concealed by vegetation established along the Ohinemuri River and remaining areas of pine plantation on Winner Hill and along western edge of the mine • Modified landform remains contained within established vegetation and surrounding landforms during operation and through mine closure as tailings storage is established Mitigation • Retain existing areas of plantation pine during mining operation as part of maintaining an existing visual screen Low Adverse Low Neutral Low Neutral G2: South-East Waihi (VS 13) • Views from dwellings and recreation areas with higher sensitivity and transport corridors with lower sensitivity • Mining activity predominantly concealed by intervening landform and vegetation • Long distance partial views of a small part of a broader vegetated skyline removed during operation Low Adverse Low Neutral Low Neutral 41 Effects during implementation before mitigation 42 Effects during operation following mitigation 43 Residual Effects at Completion 44 Level of Effect assessed as: Very High, High, Moderate-High, Moderate, Moderate-Low, Low, Very Low 45 Nature of Effect assessed as: Adverse, Neutral or Beneficial
