Auckland Regional Council consents
Appendix P: Conditions for Works in the Bed of Watercourses and Diversion of Surface Water–Consent Numbers 34372 and 34373

General

1.     The consent holder shall be responsible for all contracted operations relating to the exercise of this resource consent, and shall ensure that all personnel working on the site are made aware of the conditions of this resource consent and the Construction Management Plan required under this consent, and shall ensure compliance with those conditions.

3.     The consent holder shall appoint one or more representatives prior to the exercise of this resource consent, who shall be the Auckland Regional Council’s principal contact person(s) in regard to matters relating to the construction works. At least 10 days prior to the works authorised by this consent, the consent holder shall inform the Manager¹ of the representatives’ names and how they can be contacted within the works period. Should the person(s) appointed as representative(s) change during the works period, the consent holder shall immediately inform the Manager and shall also give written notice to the Manager of the new representatives’ names and how they can be contacted.

Pre-works requirements

4.     The consent holder shall provide designs of the specific structures, and the intended construction methodology, in sufficient detail for the size, location and likely effects to be determined, to the Manager for approval at least 1 month prior to the commencement of construction.

5.     If works affecting the beds of watercourses are not completed, or substantially completed, within 5 years of the date of commencement of this consent in terms of section 116 of the Act, the consent holder shall resubmit the designs of the specific structures, and intended construction methodology required by condition 4, including an updated timetable, to the Manager for further comment and approval.

6.     The Manager shall be informed in writing at least one week prior to the start date of any works authorised by the resource consents.

7.     Prior to works commencing on-site, the consent holder or their agent shall arrange and conduct a pre-construction site meeting between ARC, the consent holder, the primary contractor and a representative of Manukau City Council. If the construction is undertaken on a staged basis, a pre-construction site meeting may take place prior to each stage.

Contents of Construction Management Plan (CMP)

8.     A Construction Management Plan shall be prepared and have the purpose of ensuring that the activities within consent numbers 34102, 34370, 34372 and 34373, are managed in an integrated and effective manner, and in accordance with the conditions of each consent. The Construction Management Plan shall outline the consent holder’s intended approach to (as appropriate):

• storage and reuse of top soil;
• management and disposal of spoil;
• silt and dust control during earthwork stages;
• temporary activities and equipment storage in specified areas;
• water quality management;
• security and lighting during construction;
• any contaminated land management procedures;
• construction noise, dust and vibration;
• hours of work;
• existing network utilities protocols and guidelines;
• cultural and archaeological protocols (including discovery protocols);
• land stability management and water quality and sediment controls;
• geotechnical investigation techniques and management;
• vegetation clearance, disposal and restoration;
• community information and liaison procedures;
• landowner liaison (where relevant), including means of access by consent authority representatives during the construction stage;
• quality assurance/quality control;
• engineering design details;
• detailed construction methods;
• an intended construction timetable (including staging if relevant);
• construction method for watercourse crossings;
• traffic management and property access management;
• contractor training;
• an outline of procedures to be followed onsite to ensure compliance with consent conditions, rules in Regional and District Plans, legislation and regulations; and
• methodology and approval procedures for making changes to the Construction Management Plan.

The works authorised by this consent shall not be commenced prior to such approval of the Construction Management Plan.

10.     Any changes to the Construction Management Plan shall be made in accordance with the methodology and approved procedures in that plan and shall be confirmed in writing by the consent holder following consultation with the Manager, before implementation

11.     The consent holder shall carry out operations in general accordance with the provisions of the approved Construction Management Plan.

Construction activities

12.     The consent holder shall provide the Manager with an updated schedule of construction activities, completed for the previous month and intended for the following month, at the end of each month during the duration of the works.

Stream work

13.     No contaminant (including but not limited to oil, petrol, diesel, hydraulic fluid) shall be released into water from equipment being used for the activity and no machinery shall be cleaned, stored, or refuelled within 10 metres of the stream.

14.     Any erosion of the stream bed or banks that is attributable to the works shall be repaired by the consent holder to the satisfaction of the Manager.

15.     All works affecting the stream, including tidy up on completion of the works, shall be to the satisfaction of the Manager.

16.     The consent holder shall ensure that:

• the works are undertaken in a manner that does not impede fish passage; and
• any fish stranded as a result of the diversion are immediately placed back in the active flowing channel of the stream.

17.     During the implementation of the works within the Turanga Creek, the Mangemangeroa Stream and the unnamed stream above Dunvegan Rise and below Point View Drive, the consent holder shall take all practicable steps to minimise sediment loading and increased turbidity of the watercourses, including but not limited to:

• implementing provisions for erosion and sediment control within the Construction Management Plan required under condition 8 above and the Erosion and Sediment Control Plan required under consent number 34102; and
• ensuring that no construction materials or debris enter the stream flow; and
• operating all machinery from the streambank or within bunded areas and not in flowing water; and
• completing all construction work in the minimum time practicable.

18.     The bridge over the Turanga Creek shall be constructed and maintained to ensure that:

• any erosion of the stream bed or bank that is attributable to the bridge is avoided or repaired;
• the waterway beneath the bridge remains clear of flood debris;
• the structural integrity of the bridge remains sound; and
• the bridge provides for the passage of fish up and down the stream.

19.     If a bridge crossing is chosen for the Mangemangeroa Stream and the unnamed stream above Dunvegan Rise and below Point View Drive, then the bridge shall be constructed and maintained to ensure that:

• any erosion of the stream bed or bank that is attributable to the bridge is avoided or repaired;
• the waterway beneath the bridge remains clear of flood debris;
• the structural integrity of the bridge remains sound; and

22.     The option chosen (bridge or culvert) for the Mangemangeroa Stream and the unnamed stream above Dunvegan Rise and below Point View Drive shall not cause more than a minor impediment to the passage of flood debris and shall be maintained free of flood debris during the construction period.

Overall environmental protection

23.     Environmental protection measures shall be carried out in accordance with those generally described in consents numbers 34102, 34370, 34372 and 34373 and the Construction Management Plan required in condition 8 and the Erosion and Sediment Control Plan required under consent number 34102, and TP90.³
