15.1 Rule Statement

District plan noise rules must recognise that virtually all activities produce some noise, and there is a need to provide a balance between the noise producer and the noise receiver. Noise and vibration are directly linked, and vibration standards are also found in this Chapter.

Historically, noise rules and New Zealand’s environmental noise standards have often been based upon existing noise levels in an area. This approach is now disappearing, as it is recognised that if there is to be development in an area, noise rules must provide an appropriate level of amenity for the developed area, whilst at the same time allowing noise generating activities to generate reasonable levels of noise. The assumption that new dwellings and/or business can be introduced into an area and somehow still maintain a noise level consistent with an undeveloped area is generally impractical. The purpose of the district plan’s noise limits is to allow development while controlling noise to an appropriate level.

The plan uses the “Leq” descriptor for the assessment and measurement of environmental noise levels and for the specification of noise limits in district plans. Leq is used in the most recent versions of all relevant environmental acoustic standards. It is the energy average of noise during a specified period, and is commonly known as the average noise level. “Lmax” controls are also used during night-time hours, to limit the short duration “peak” noise levels that are correlated with sleep disturbance.

The plan’s rules for Town Centre, Business and Industrial zones contain requirements for residential units in these zones to be acoustically insulated against intrusive noise from external sources. This is to help avoid complaints from future residents about business activities inhibiting otherwise legitimate activity in such zones.

Noise control boundaries have been calculated around the District’s hydro electric power generating facilities on the Waikato River and the key industrial sites at Kinleith, Lichfield and Tirau. This approach gives certainty to the surrounding residents about future noise levels, and flexibility to the industrial operator in planning future development and alterations. Acoustic insulation will also be required for residential buildings inside these control boundaries, to recognise the higher than usual noise levels and give the residents concerned an adequate standard of amenity.

A number of activities have been identified as requiring exemption from the standard noise limits, often because they vary widely throughout the year and are temporary and transient. Strict compliance with standard noise rules may not be practicable, reasonable or enforceable. Such activities are required to comply with alternative noise limits specified in Table A2.

Poorly designed and directed lighting can cause a nuisance for neighbours, including sleep disturbance, and affect traffic safety. Glare sources such as security lighting and illuminated signage in all zones will therefore be required to meet specified glare standards.

15.2 Anticipated Environmental Results

The noise rules are intended to achieve the following anticipated environmental results:

Commercial and industrial zone noise rules which allow intended activities to take place

Safeguarding the amenity levels of Residential, Rural Residential and Rural zones from intrusive noise and glare, particularly at night

Avoiding reverse sensitivity issues arising from potentially noise sensitive activities such as dwellings being developed in business and industrial zones, or near other noise generators.

The noise, vibration and glare rules are a method to implement the objectives and policies contained within Chapter 4 (Objectives and Policies for the District’s Towns), Chapter 5 (Objectives and Policies for the District’s Rural Areas), and Chapter 7 (Objectives and Policies for the District’s Infrastructure and Development).

Note:

Although AS/NZ 2107:2000 recommends 30dBA as the satisfactory internal design sound level for bedrooms, such standards may be technically difficult and costly to achieve in high noise areas. 35 dBA Leq(24hr) is therefore acceptable.

15.4 Measurement and Assessment - Noise

(a)
Noise shall be measured and assessed using the following standards:

NZS 6801:2008 Acoustics – Measurement of Environmental Sound

NZS 6802:2008 Acoustics – Environmental Noise

NZS 6803:1999 Acoustics – Construction Noise

NZS 6805:1992 Airport Noise Management and Land Use Planning

NZS 6806: 2010 Acoustics – Road traffic Noise: New and altered roads

NZS 6807:1994 Noise Management and Land Use Planning for Helicopter Landing Areas

NZS 6808: 2010 Acoustics – Wind farm noise

(b)
Noise levels shall be measured and assessed in accordance with the relevant Standard(s).
(c)
Where a scenario arises where the standards above are not best suited in assessing the noise source or receiver of interest, Council may through the resource consent process agree to the use of alternative standards.

15.5 Alternative Noise Measurement Position

Alternative measurement location(s) to those specified above may be appropriate where acoustic standards suggest an alternative measurement location, or on a case by case basis as may be agreed through the resource consent process. This shall be discussed and agreed with appropriate Council staff. Any reports submitted to Council shall describe the use of an alternative measurement position and the reasons for its use.

15.6 Measurement and Assessment - Vibration

(a)
Vibration from any activity (excluding mineral exploration, mining and quarrying, as specifically provided for in Rule 15.3.2 Table A2) shall be measured and assessed in accordance with the following standards:

AS 2670.1-2001 Evaluation of human exposure to whole-body vibration – General requirements

AS 2670.2-1990 Evaluation of human exposure to whole-body vibration - Continuous and shock-induced vibration in buildings (1 to 80 Hz)

DIN 4150-3:1999 Effects of vibration on structures

(b)
Where a scenario arises where the standards above are not best suited in assessing the vibration source or receiver of interest, Council may through the resource consent process agree to the use of alternative standards.

15.7 Lighting and Glare

Effects of lighting are calculated using the procedure in NZS 6701:1983 Sections 6 and 7. For any light received at a residential, rural residential or rural property a comparison of the light generated at the source and the component having an effect on the receiver with a threshold increment (TI) of 20% or greater is deemed to be glare.

In addition the effect from the source shall not exceed an absolute increment on the ambient level of light specified in the following clauses:

a)
At no time between the hours of 7.00am and 10.00pm shall any outdoor lighting be used in a manner that causes an added illuminance in excess of 125 lux, measured horizontally or vertically at the boundary of any Residential, Rural Residential or Rural zoned site adjoining
b)
At no time between the hours of 10.00pm and 7.00am shall any lighting be used in a manner that causes:
i)
An added illuminance in excess of 10 lux measured either horizontally or vertically at the glazing of a habitable room of an adjoining dwelling within a Residential, Rural Residential or Rural Zone
ii)
An added illuminance in excess of 20 lux measured either horizontally or vertically at any point along the boundary of a property zoned residential, rural residential or rural.

Where measurement of any added illuminance cannot be made because any person refuses to turn off lighting, measurements may be made in locations of a similar nature that are not affected by such lighting.

c)
Rules 15.7a) and 15.7b)ii) above shall not apply to any lighting from sites in the Industrial zone, or from normal intermittent agricultural practices such as harvesting, measured at sites that are not zoned Residential
d)
All lighting on any site adjoining a Residential, Rural Residential, or Rural zoned site shall be selected, located, aimed, adjusted and screened to ensure that glare resulting from the lighting does not exceed a TI of 20%
e)
Lighting of traffic access and parking areas shall be selected, located, aimed, adjusted and screened to ensure that stray light effects resulting from vehicles are mitigated.
f)
No building shall be constructed and/or left unfinished and/or clad in any protective material or cover which could reflect sufficient light to detract from the amenities of the neighbourhood or cause discomfort to any person resident in the locality. Material used in the construction or cladding or protection of a building from which discomfort glare is likely to occur should have a reflective value not greater than 20%
g)
Development on all properties adjacent to State Highways should be undertaken in such a way that the emission of light from these properties does not adversely affect the safety of drivers on State Highways in accordance with NZTA policy

Where lighting and glare may affect the safe and efficient operation of any road, including a State Highway, consideration shall be given to Australian Standard 4287–1997 Control of Obtrusive Effects of Outdoor Lighting

h)
Signage shall be constructed to comply with the following levels of luminance:

Daytime – 25 lux 

Night-time – 10 lux

Luminance levels shall be measured vertically or horizontally anywhere along the affected site boundary in accordance with professional illumination engineering practice or any relevant NZ Standard.

i)
No light source used for illuminating a sign, except for neon and side-emitting fibre optics, shall be visible to motorists on any road or road reserve

Rules a) to h) above specifically exclude the lighting and glare effects generated from street lighting, and from Christmas lights and similar temporary festive illuminations.

Any activity that cannot comply with these provisions will require restricted discretionary resource consent.
