23. Airport Zone Volume Two 23.2.2. Noise. 23.2.2.1. Noise from a source other than an aircraft movement, aircraft engine testing, or a national or international gliding event, must comply with the following noise limits measured at or within the boundary of any land zoned Urban Residential 1, Urban Residential 2 (including Greenfields) or Urban Residential 3, or at or within the notional boundary of any noise sensitive activity on any land zoned Rural Environment: Monday to Saturday 7.00 am to 6.00 pm 55dBA L Aeq Monday to Saturday 6.00 pm to 10.00 pm 50dBA L Aeq Monday to Sunday 10.00 pm to 7.00 am 45dBA L Aeq Monday to Sunday 10.00 pm to 7.00 am 70dBA L max 23.2.2.2. Noise must be measured in accordance with the provisions of NZS 6801:2008 Acoustics – Measurement of Environmental Sound, and assessed in accordance with NZS 6802:2008 Acoustics – Environmental Noise. 23.2.2.3. Construction noise must not exceed the recommended limits in, and must be measured and assessed in accordance with, NZS 6803:1999 Acoustics – Construction Noise. 23.2.3. Siting of a noise sensitive activity in the Woodbourne Airport Zone. 23.2.3.1. A new noise sensitive activity within the area between the Outer Noise Control Boundary and the Inner Noise Control Boundary must have appropriate acoustic insulation to habitable spaces installed to ensure a satisfactory internal noise environment. Such insulation must provide an indoor sound environment not exceeding Ldn 40dBA and must be certified by an acoustic engineer as adequate to achieve the design standard. 23.2.3.2. An alteration or addition to an existing noise sensitive activity within the area between the Outer Noise Control Boundary and the Inner Noise Control Boundary must have appropriate acoustic insulation to habitable spaces installed to ensure a satisfactory internal noise environment. Such insulation must provide an indoor sound environment not exceeding Ldn 40dBA and must be certified by an acoustic engineer as adequate to achieve the design standard. 23.2.4. Land use activity in the Woodbourne Airport Zone. 23.2.4.1. A new road must not be constructed where a take-off climb/approach or a transitional slope would pass at a lower height than 4.67m vertically above the road. 23.2.5. Siting of a noise sensitive activity in the Picton (Koromiko) Airport Zone. 23.2.5.1. A new noise sensitive activity within the area between the Outer Noise Control Boundary and the Inner Noise Control Boundary must have appropriate acoustic insulation installed to establish an internal noise environment. Such insulation must provide an indoor sound environment not exceeding of 35dBA L Aeq at night time with the windows closed and must be certified by an acous tic engineer as adequate to achieve the design standard. 23.2.5.2. An alteration or addition to existing noise sensitive activity within the area between the Outer Noise Control Boundary and the Inner Noise Control Boundary must have appropriate acoustic insulation installed to establish an internal noise environment. Such insulation must provide an indoor sound 23 – 4
