Landscape mitigation: public land
30. Within 12 months of confirmation of the designation, Transpower shall write to t
he council, and where relevant NZTA, informing it or them of its proposal to carry out landscape mitigation along specific sections or locations of roads and State highways in the Council’s district, as shown on Maps 32–39 of Appendix V and seeking the council’s involvement in implementing the mitigation. The offer shall be for the purpose of mitigation of adverse visual effects of the overhead line when viewed from the public roads or other viewpoints shown in Maps 32-39 of Appendix V.
31. On receiving a positive response from the council and/or NZTA (as applicable), Transpower shall provide a draft development plan, specifications, and costing prepared by a qualified landscape architect as an offer to the council and/or NZTA. The offer shall remain open for 12 months following commissioning of the line.
32. Transpower shall review any comments provided by the Council and/or NZTA and shall issue a final plan. The final plan shall be provided as soon as practicable to the Council and/or NZTA.
33. On the Council’s and/or NZTA’s written acceptance of the plan (where relevant) and agreement to implement the mitigation, Transpower shall, within 30 days, pay to the Council and/or NZTA the cost specified in the accepted plan (which shall include an estimate for a year of maintenance).
34. Transpower shall not be in breach of condition 31 to 34 in the event the Council and/or NZTA do not undertake the planting as provided in the final plan.
Pre-construction activities
35. Prior to construction commencing, Transpower shall appoint a Landowner Liaison Officer, who will:
(a) be responsible for maintaining contact with landowners and occupiers of each property prior to, and during construction; and
(b) have a contact role with the landowner during the development of the Site Works Plan for individual properties.
36. Transpower shall make copies of individual SWPs available to council (formerly Franklin District Council) for information purposes, upon request.
Construction Management Plan (CMP)
37. Prior to commencement of any construction activity authorised by the designation, Transpower shall submit a construction management plan to the Group Manager: Environmental Services for approval. The Group Manager: Environmental Services shall respond within 20 working days. Approval shall not be unreasonably withheld. The construction management plan shall outline Transpower’s intended approach to:
(a) land stability management and sediment controls;
(b) storage and reuse of topsoil;
(c) management and disposal of spoil;
(d) groundwater and stormwater management, treatment and disposal;
(e) silt and dust control, during earthwork stages;
(f) traffic/access management;
(g) temporary activities and equipment storage in specified areas;
(h) security and lighting during construction;
(i) contaminated land management procedures;
(j) construction noise (as set out in conditions 39-42), dust and vibration;
(k) hours of work;
(l) existing network utilities’ protocols and guidelines;
(m) subject to other specific conditions, cultural protocols and archaeological requirements;
(n) vegetation clearance, disposal and restoration;
(o) the intended construction programme (including staging if appropriate);
(p) protocols and procedures for road controlling authorities and rail operators, where the line crosses that infrastructure;
(q) community information and liaison;
(r) contractor training; and
(s) generic contents of Site Works Plans (SWPs).
Nothing in this condition allows the Council, or any other party, to require more onerous controls than contained in the designation conditions.
Construction and maintenance noise
38. All construction and maintenance work shall be designed, managed and conducted to ensure that construction and maintenance noise from the designated area does not exceed the limits in NZS6803:1999 Acoustics– Construction Noise at locations set out in section 6.2 of that standard.
39. The noise limits required by condition 39 shall not apply to emergency work required to re-establish continuity of supply, urgently required to prevent loss of life or other personal injury or commissioning works, but all practicable steps shall be undertaken to control noise and to avoid adverse noise effects particularly at times when the stricter noise limits apply (eg, at night time).
40. Prior to any significant construction work taking place, including any earthworks, a noise management plan applicable to the construction and commissioning stages shall be prepared for the whole of the line, with the assistance of a suitably qualified and experienced person. The plan shall set out the management procedures in terms of section 8 and Annex E of NZS6803:1999 and the works shall be undertaken in accordance with that noise management plan.
41. The noise management plan required by condition 41 shall be submitted to the Group Manager: Environmental Services at least 20 working days prior to the works commencing.
Vibration
42. Vibration from all construction activities shall not exceed the limits of, and shall be measured in accordance with, German Standard DIN 4150-3 (1999-02) Structural Vibration – Effects of Vibration on Structures.
Aviation
43. Transpower shall,
on a monthly basis during the construction of the line, inform the New Zealand Agricultural Aviation Authority, the Civil Aviation Authority and Ardmore Airport Limited (in relation to the towers within the conical surface only, as set out in the Appendix Map 8, Ardmore Aerodrome Protection Measures, Auckland Council District Plan (Manukau Section) 2002) of the construction activities completed in the previous month, and intended to be undertaken in the following month including:
(a) erection of specific towers (with locations and heights); and
(b) stringing of conductor and earthwires between specified towers.
For the avoidance of doubt, the requirement in condition 44 applies to each tower and conductoring of each tower, not merely the commencement of tower erection or conductoring.
Traffic Management Plan (TMP) for road crossings and local roads
44. Transpower shall prepare a series of traffic management plans for road crossings and local roads used by heavy traffic in accordance with Transit New Zealand’s Code of Practice for Temporary Traffic Management (COPTTM), after consultation with (as relevant):
(a
) Auckland Transport (Road Controlling Authority);
(b) New Zealand Transport Agency (NZTA); and
(c) The following key stakeholders:
(i) emergency services (including police);
(ii) bus operators;
(iii) schools;
(iv) Housing New Zealand Corporation;
(d) Any additional key stakeholders identified by council.
45. A TMP shall be submitted to the council and NZTA (where relevant) at least 20 working days prior to the commencement of construction of the relevant road crossing works, or works affecting local roads. The plans may be submitted in stages, with each stage being submitted at least 20 working days prior to the commencement of the work the subject of that stage.
46. The council shall respond within 20 working days indicating whether approval is given or refused. Approval shall not be unreasonably withheld.
47. The TMP prepared by Transpower shall recognise that the paramount purpose of roads is the free passage of the public and its vehicles.
48. The TMPs shall address and provide details of proposed road crossing works and general use of local roads by heavy vehicles and/or mitigation measures relating to the following matters:
(a) details of the installation of any protection measures including, but not limited to, hurdles for subsequent line construction purposes;
(b) details of any necessary temporary road closures, diversions, or deviations which are likely to be required during road crossing activities, including the likely date, time, and duration of such matters (any necessary temporary road closures should be effected during off-peak periods unless this is impracticable or would have adverse impacts on adjacent properties);
(c) where diversions or deviations are required, information shall be provided by a suitably qualified and experienced traffic engineer of the traffic volumes and capacities of alternative routes, to ensure that such routes are both convenient and capable of safely accommodating any such diverted or deviated traffic;
(d) details of the proposed signage to advise motorists, residents, stakeholders, and other road users of any road closures, diversions and delays, such signage to be sufficiently clear to be capable of ready understanding by the general public and installed at appropriate locations at least 7 days in advance of such road closures, diversions and delays;
(e) details of methods of proposed information dissemination regarding construction activities and associated traffic effects, including but not limited to public notices in newspapers, radio announcements, information packages and direct contact with affected persons. (Such information dissemination, and the chosen method of dissemination is to be proportional to the impact);
(f) Details of prior consultation or community liaison undertaken with affected residents, stakeholders, public transport providers, emergency services or representative groups regarding proposed road closures, diversions and delays, and any measures agreed with such groups to address any adverse effects or inconvenience that may arise; and
(g) identification of any measures for the purposes of mitigating adverse traffic effects of construction traffic, including safety matters (such speed restrictions and signage), relating to cyclists, pedestrians, disabled persons, and schoolchildren.
Advice note:
1. If temporary road closure is required, additional time may be necessary to allow the Road Controlling Authority to complete the consultation and give the public notices required under section 342 and schedule 10 of the Local Government Act 1974.
Construction entranceways off public roads
49. Prior to the commencement of construction, Transpower shall undertake a survey of the condition of the roads in the immediate vicinity of construction entranceways off public roads (consisting of a photographic survey).
50. Transpower shall repair any damage to entranceways and public roads in the vicinity of those entranceways resulting from impacts of its construction traffic.
General advice note:
1. In relation to the ARI-PAK A towers outside of the designated area, Transpower shall use its best endeavours to establish and follow the procedures in the conditions in relation to cultural/spiritual matters, construction noise, the preparation of the construction management plan and pre-construction activities.
