1 231 Section 10 Residential Zone

2 Proposed Draft Amendments to Section 10: Residential Note: new text to be added to the District Plan is shown as coloured underlined and text to be removed is shown in coloured strikethrough. 10. RESIDENTIAL ZONE 10.3 Objectives and Policies Within the broad framework of the City View objectives in section 2, the following specific objectives and policies were identified for the residential area: Objective To avoid, remedy or mitigate the adverse effects of aircraft noise on noise sensitive activities in the vicinity of the Palmerston North Airport. Objective 7 To avoid, remedy or mitigate the potential adverse effects of noise sensitive activities in the vicinity of Palmerston North Airport on efficient airport operations To avoid, remedy or mitigate the adverse effects of aircraft noise on noise sensitive activities in the vicinity of the Palmerston North Airport, while protecting the Palmerston North Airport from the potential adverse effects of noise sensitive activities on efficient airport operations. Policies 76.1 To prohibit any new dwelling, school, or other building to be used for regular living accommodation in the Air Noise ZoneContour To mitigate the adverse effects of aircraft noise on any new dwelling, school, hospital or other building to be used for regular living accommodation or the regular assembly of people in the Inner and Outer Control ZonesContours by specifying appropriate insulation standards.the types of sound insulation to meet insulation ratings. 7.3 To enable Council consideration of alternative types of sound insulation for habitable buildings in the Inner and Outer Control Zones through resource consent procedures. 7.4 To require every application for a resource consent for a habitable building within the Inner and Outer Control Zones to be accompanied by details of the method of construction for the purpose of noise attenuation, and sufficient information to satisfy Council that this method will achieve the requisite insulation rating. Explanation The operations of a modern airport give rise to a range of sound emissions relating mainly to aircraft operations. These sound emissions may adversely affect surrounding noise sensitive activities such the inhabitants of dwellings. In order to protect potential occupiers of land situated within the vicinity of the airport from levels of noise that may be incompatible with normal standards of residential amenity, Council has introduced controls to avoid or mitigate the adverse effects of operational aircraft noise on noise sensitive residential activities. These controls also have the effect of protecting the operation of the Airport from noise sensitive activities to allow it to function efficiently, effectively and safely. To ensure that responsibility for mitigation of operational aircraft noise is not borne solely by affected residential property owners, Council has also introduced specific noise mitigation measures to control operational activities within the Airport Zone. Please refer to Rule Sound Emissions in the Airport Zone.

3 Methods District Plan Rules (Palmerston North City Council) Public Education Designation The community s desire for a high level of amenity within the Residential Zone means that a regulatory approach through the rules in this and other sections will be the most cost efficient and effective means of achieving the objectives and policies. However, public education in the form of landscape and building design guides may also assist in achieving some of the amenity and design concerns of the objectives and policies, thereby achieving effective compliance at little cost to the community. In respect of any land severely affected by airport noise, one of the options available is for the Requiring Authority to designate land for airport purposes (and subsequently purchase it) or to simply purchase land without designation. Palmerston North Airport Limited was granted requiring authority status in July 1995 however, to date the Company has not exercised its designating powers for this purpose Rules: Permitted Activities R Dwellings and Accessory Buildings (excluding those prohibited by Rule ). Any dwelling will meet the Performance Policies below and will be a Permitted Activity where they comply with the Performance Standards, detailed in Clauses (a) to (j) Performance ConditionsStandards (a) Height - including Maximum Height and Height Recession Planes.

5 235 NOTE TO PLAN USERS Proposals that do not: 1. Provide the required degree of noise reduction stated in the definitions of Schedules P, Q and R; or 2. Obtain certification from an acoustical consultant to provide alternative means of construction to achieve the degree of noise reduction set out in the definitions of Schedules P, Q and R; are provided for as a Non-Complying Activity under R All habitable rooms must be designed, constructed and maintained in accordance with a design report prepared by a suitably qualified and experienced member of the Acoustical Society of New Zealand stating that the proposed design will achieve compliance with the the requirements of performance standards (h)(i) (ii), including a 5dBA safety margin. (iv) Ventilation - Where bedrooms with openable windows are proposed, a positive supplementary source of fresh air ducted from outside is required at the time of fit-out. For the purposes of this requirement, a bedroom is any room intended to be used for sleeping. The supplementary source of air is to achieve a minimum of 7.5 litres per second per person. NOTE TO PLAN USERS Proposed activities that do not meet the performance standards in (h) are Non-Complying Activities under R The following deeming provisions apply in circumstances where a proposed dwelling/ building straddles the boundary of noise contours shown on Map : 1. Where a dwelling/building is proposed on the 55 Ldn noise contour line, the dwelling/ building is deemed to be outside of the Outer Control Contour. 2. Where a dwelling/building is proposed on the 60 Ldn Noise Contour line shown on Map , the dwelling/building is deemed to be within the Outer Control Contour. 3. Where a dwelling/ building is proposed on the 65 Ldn noise contour line, the dwelling/ building is deemed to be within the Air Noise Contour. Explanation As a consequence of air noise projection work and other investigative work undertaken by Palmerston North Airport Limited, and the Palmerston North City Council respectively, a large area of land surrounding the Palmerston North Airport has been identified as being subject to varying levels of noise exposure associated with aircraft operations. The noise emission levels resulting from these operations have been predicted using methods recommended by New Zealand Standard 6805: Airport Noise Management and Land Use Planning. Noise emission levels are identified as equal loudness contours around the airport. Map Air Noise Control included in this Plan defines these contours and identifies those areas around the airport, expressed as discrete noise zonescontours, within which specific noise attenuation measures apply. Materials and methods of construction are described in Schedules P, Q and R. If properly built and maintained buildings constructed of the materials will be deemed to reduce the exterior A weighted aircraft noise levels by the following decibels with respect to the interior A weighted sound levels: Schedule P Schedule Q Schedule R 20 decibels 25 decibels 30 decibels For the purposes of this Plan, three distinct noise zonescontours have been developed as follows: (a) Air Noise ZoneContour - the Air Noise boundary is generally the 65 Ldn noise contour. Due to the high level of aircraft operational noise predicted within this zonecontour the establishment of any new noise sensitive activities, such as dwellings, are prohibited.

6 236 (b) (c) Inner Control ZoneContour - the Inner Control ZoneContour incorporates the land between the 60 Ldn and 65 Ldn predicted noise contours. The objective of this ZoneContour is to provide for a level of sound insulation in the design of dwellings and other buildings used for regular accommodation which adequately reduces the level of noise exposure experienced. The level of sound insulation identified in the schedules P, Q and R are based on both the maximum Ldn noise prediction and the maximum single noise event generated by an aircraft at night. Outer Control ZoneContour - the Outer Control ZoneContour incorporates the land between the 55 Ldn and 60 Ldn predicted noise contours. The objective of this ZoneContour is to provide for a level of sound insulation in the design of dwellings and other buildings used for regular accommodation which reflects the reduced level of aircraft noise exposure experienced within this area. As the maximum aircraft noise level in this ZoneContour is five decibels less than in the Inner Control ZoneContour, sound insulation requirements are also correspondingly reduced by five decibels. The materials provided in the Schedules include a safety factor of 5dBA to ensure that when built the insulation does not fail to provide the requisite degree of aircraft noise reduction. Accordingly, to be permitted, any proposal utilising alternative means of insulation to that prescribed in the Schedules, shall also include a 5dBA safety margin. In preparing a certificate stating that the relevant insulation standard will be met an acoustical consultant will need to calculate that the noise reduction of the proposed alternative construction will at least be equivalent to that provided by the relevant applicable Schedule. This includes the prescribed 5dB safety margin. The noise reduction provided by Schedules P, Q and R is set out in the Definitions Section. The calculation relates specifically to aircraft noise. To ensure that calculations are undertaken on a consistent basis the A weighted aircraft noise level is also defined by reference to Table G1 of Australian Standard AS This defines the spectral frequency content of aircraft noise. (See Definitions: Acoustical Consultant; Schedule P; Schedule Q; Schedule R; and Exterior A Weighted Aircraft Noise Levels).
