5.2. Noise and Vibration Monitoring
Noise monitoring has been undertaken for new plant and activities since the start of construction works
in January 2012 to assess levels against noise predictions (As provided in the Construction Noise and
Vibration Management Plan) and to confirm compliance with the project noise criteria. Compliance has
been measured against Consent conditions CNV.2 for noise, CNV.3 for noise from air blast and CNV.4 and
CNV.5 for vibration.
The focus for noise and vibration during October has been:
Monitoring of noise and vibration for drill and blast in Southern approach trench and for
construction of Alan Wood Reserve stormwater pond.
Monitoring of noise where rock breaking for the sewer alignment (Southern area) in close
proximity to the residential properties.
Monitoring of site establishment works in northern area.
The table below shows the maximum measured noise levels for activities undertaken in October at noise
receivers. There were no measured exceedences of project noise criteria set out in CNV.2 measured at
relevant noise receivers.

Vibration and noise monitoring for the Southern area blasts was undertaken by Styles Group. A report of
their findings during October is appended. The results showed compliance with project vibration limits set
out in CNV4 and CNV.5 and CNV3 for noise from air blast.
Three Site Specific Noise Management Plans (SSNMP) were submitted to Auckland Council and approved in
October. These were SSNMP#8, in relation to construction of temporary stormwater and sewer line under
Richardson Road, SSNMP#9, in relation to stream realignment ‘A’ tie ins and SSNMP#10, in relation to
installation of Super-T Beams for Richardson Road Bridge . These works have been completed.
In relation to noise mitigation, to date, temporary noise walls have been installed along the site boundary
at:
17-33 Whittle Place
21-33 Valonia Street
231 Richardson Road
194a-166 Methuen Road
57 -91 and 129 Hendon Avenue (Extended from 3m to 4m from 77-87 Hendon Avenue)
194-204 Methuen Road
Earth bund barriers have been installed along the boundary of 107 Hendon Avenue to 115 Hendon Avenue
to provide mitigation with the removal of these houses in September. A 3m plywood noise wall was
installed in October from 115 to 123 Hendon Avenue to complete the noise barrier along this section of
Hendon Avenue following the removal of houses.
The table below shows the over pressure and maximum vibration levels recorded for each blast
undertaken in October. The monitoring was carried out at the nearest dwelling and also the nearest
occupied dwelling (closest receiver). There were two measured exceedences of the peak sound pressure
level set out in CNV.3 measured at the closest receiver (on the 23rd and 29th of October. Maximum
recorded was 124dB). There were also two measured exceedences of the peak particle velocity set out in
CNV.5 measured at the closest receiver (on the 11th and 24th of October. Maximum recorded was
11.4mm/sec).

5.3. Air Quality Monitoring
Two Total Suspended Particulate (TSP) analysers and one met mast are required in the Southern Area
(Sector 9) under consent conditions AQ16 and AQ17. One TSP analyser with met mast is required in the
Northern Portal Area (sector 7) with the start of construction in October 2012.
Two E-BAM TSP monitors are currently co-located at a site in Hendon Park considered representative of
relevant exposure to the Southern area main works. The co-location of the E-BAMs has enabled
assessment of the performance of the monitors. A correlation of 0.8 has been achieved. A second site has
been set up in Alan Wood Reserve at the rear of residential properties along Hendon Avenue, as agreed
with Auckland Council. This will allow greater coverage across the Southern Area Main Works
construction activities. There are currently sewer alignment works in the area of Alan Wood Reserve
where one of the the E-BAMs will be moved to, so this will remain at Hendon Park until the sewer works
have been completed there.
The power to the Hendon Park E-BAMs was lost on 18th September 2012 with the demolition of the
adjacent housing on Hednon Avenue to enable the Watercare sewer diversion to be constructed. Power
was reinstalled on 23rd November 2012. Auckland Council have continued to be updated with progress
with this and additional visual checks on dust have been made during this down time in the absence of
real time monitoring results.
The Northern area E-BAM was installed at Waterview School on the 9th October 2012. This provided data
until the 23rd October 2012 when the Waterview School Board requested it be closed down. A new site
will be installed outside the School grounds and is awaiting installation of a power line by suppliers
Vector.
E-BAM results for October are available for the Waterview School site and show levels below the project
consent limit and short-term trigger levels for TSP with the exception of the following episode.
11/10/12 13-14pm and 3-4 pm– EBAM3 showed levels of >200µg/m3 (Maximum 527 µg/m3) for
2 hours. This was during school holidays during early site clearance works and prior to
installation of the noise wall at Waterview School. No further exceedences were recorded that
day.

5.4. Ground Water Monitoring
Monthly monitoring for piezometers identified in Appendix A of the Groundwater Management Plan
(GWMP) is ongoing, with the exception of around 22 piezometers around the tunnel which are still to be
installed (as per the rev 4 GWMP).
Piezometers located within 150 m of the Southern Approach trench have been monitored weekly since
June (Appendix B), in advance of excavation above the water table that commenced in July. Dewatering
activities commenced in September when groundwater was encountered in the excavation (at a depth of
approximately 9 m below ground level). Accordingly more intensive monitoring of groundwater levels
around the Southern Approach Trench (twice-weekly in accordance with condition G.6) has commenced.
Piezometers in close proximity to the trench (i.e. less than 30 m distance) have recorded a drop in
groundwater level of between 2 m and 4 m, with some wells showing a slight recovery during the month
of October due to reduced dewatering in some areas. Wells that are very close to the trench (i.e. BHA4,
BHB1 and BHB4) show the effects of pumping from the low point sump, with short term peak drawdowns
of up to 5.5 m in the alluvium, 7 m in the East Coast Bays Formation rock, and up to 6 m in the basalt.
At a distance of 30 m to 120 m groundwater levels have lowered by up to 2 m; beyond a distance of 120
m there is negligible drawdown. Groundwater levels for all piezometers remain above proposed trigger
levels (Figure 1).
Figure 1: Drawdown vs Distance Graph for SAT
Continuous pre-construction monitoring of Oakley Creek base flow is ongoing with data reviewed
monthly; to date, all recorded flows remaining within the expected seasonal range. Dewatering activites
will trigger 3-monthly reporting, and review of flow data by a hydrologist and freshwater ecologist in
accordance with condition G.12 in December.
5.5. Settlement Monitoring
Monthly monitoring of framework ground settlement markers identified in the Settlement Effects
Management Plan (SEMP) continues.
Framework markers within 150 m of the Southern Approach Trench have been being monitored weekly
since June (Appendix B). Recorded vertical movements are within the pre-construction seasonal range
and in many cases within the accuaracy of the survey (+/- 3 mm).
Surveyed levels for all markers are above proposed trigger levels.
5.6. Ecological and Water Quality Monitoring Oakley Creek
Construction phase water quality monitoring has been carried out monthly, as required by consent
conditions. Results for January to October 2012 are summarised in Figures 1 to 6 below. Full laboratory
reports are available on request.
Concentrations of all contaminants were consistent with those measured earlier in the construction
phase, and comparable to pre-construction baseline levels.

To respond to this, event-based water quality and/or ecological (macroinvertebrate) monitoring was
carried out at several sites on Oakley Creek (E1, E2, WR3, O4, O5, O6) on 26, 27, 29 and 31 October. The
results of this monitoring have been separately reported to Auckland Council. In summary, there is no
evidence of long-term adverse effects on water quality or macroinvertebrate communities.
Fieldwork for the second 6-monthly round of monitoring (prior to the commencement of the 2012-2013
earthworks season) was carried out in late September, and the report is currently being finalised.
Auckland Council, iwi and MFish/MPI have been notified of the Alliance’s intention to relocate fish from
the section of Oakley Creek/Te Auaunga which will be affected by the Diversion A works. This relocation
work is nearing completion (final relocation expected to happen in the week commencing 26 November).
The final numbers/species relocated at Diversion A will be advised to stakeholders in due course, as
required by the MFish/MPI permits to capture and transfer.
Fortnightly monitoring of significant vegetation, including geraniums, continues to be carried out. All
translocation of geranium plants from areas that will be affected by the works has been completed. This
has included successful transplanting into the Diversion C area.
At least one pair of NZ dotterel have been found nesting on the traffic island at the Great North Road
interchange. That area of the site has been cordoned off and drillers who have been conducting
geotechnical investigations at the site have been advised to stay out of the area.
We have been advised by Friends of Oakley Creek that an arson event on 19 November caused a fire in
the Lizard Relocation Site (adjacent to Oakley Creek, behind Unitec). Approximately 25-30% of the recent
plantings have been lost, although the fire was outside the main area where logs had been placed to
provide additional lizard refugia. We are investigating whether any of the predator bait stations have
been destroyed, and what remedial action might feasibly be undertaken by Friends of Oakley Creek or the
Well-Connected Alliance.
5.7. Contaminated Soil Monitoring
Earthworks in October 2012 requiring off-site disposal of soil comprised those from the following
locations:
Watercare /Hendon sewer;
Southern Approach Trench;
Northen Portal Approach Trench.
Table 5.1 below provides a summary of the volume of spoil disposed from the Southern Area works since
the previous monitoring report. About 49,202 tonnes of soil, 38,000 tonnes of basalt rock and 3,252.68
tonnes of refuse were removed from site. They were removed to Three Kings Managed Fill site,
Greenmount Managed Fill site, Wiri Cleanfill and Redvale Landfill.
The topsoil containing slightly elevated BAPeq soil from the Valonia Wetlands works is now proposed to
be reused on site. Contaminant concentrations of the topsoil stockpiled on the site (refer Valonia 1,
Valonia 2, Stockpile 2 S1 and Stockpile 2 S2 samples in laboratory reports in Appendix A) are below
human health criteria for recreational land use and Auckland Regional Plan: Air Land and Water
permitted activity criteria. The results show that reuse is appropriate. The base of the excavation of the
slightly elevated BAPeq soil has also been validated. The validation testing (refer samples HS1 and HS2 in
the laboratory report in Appendix A) show metal and hydrocarbon concentrations within published
background concentration range for the Auckland Region.
Table 5.2 provides a summary of the volume of spoil disposed from the Northern Portal Area works which
commenced on 1 October 2012. About 520 tonnes of clay soil have been removed to Three Kings
Managed Fill site from the vicinity of the northern portal area following demolition of the houses along
Great North Road and works relating to the Waterview Reserve open space area at the corner of
Waterbank Crescent and Herdman Street.

6. Stakeholder Management
6.1. Stakeholders
We have made significant progress in terms of community engagement this last month, having increased
our staff numbers in this area. Dedicated stakeholder managers and support staff have been engaging
directly with the southern and northern sector communities most affected by the works. This face-to-face
communication has been reinforced by printed media including construction updates, signage, flyers and
local newspaper advertising and editorial.
The recent Community BBQ in Waterview was a massive success, and generated a positive response from
many of these community members. In the southern sector, our efforts remain focused around the
management of blasting and rock-breaking impacts on Hendon Ave residents.
