Background and Description of Proposal
The applicant is proposing to redevelop the former Church College Campus site for a variety of different
land uses. Specifically, the current applications relate to Stages 2 and 3 of the site redevelopment which
will comprise a senior housing development, general residential development, commercial development
and large areas of open space.
For the most part, the following background information and description of the proposed activities
discussed below are taken directly from the application at the request of the Applicant.
2.1
Background
The Church College site was operated as a secondary school and boarding facility from 1958 to 2009.
Following the schools closure the Applicant (also the owner of the site) has given significant
consideration to the future use of the property and is now progressing works towards the
redevelopment of the site. The redevelopment plans include a large chapel/pavilion facility (referred to
Doc # 9728472
as the Stake Centre), a retirement village, mixed intensity residential development, commercial
development and large areas of open space.
The proposed redevelopment of the site is outlined on the Overall Development Concept Plan included
as Appendix A of the AEE. The proposed development activities are in-line with the zoning of the site as
outlined within the operative Hamilton City District Plan.
In 2013, the applicant obtained an initial suite of resource consents from Waikato Regional Council
(consent numbers 127626 -127629) to authorise the activities associated with Stage 1 of the Church
College site redevelopment activities. These activities included large scale earthworks, a stream
diversion, stream bed structures and stormwater diversion and discharges associated with development
of the large-scale Stake Centre building and associated access/parking and formation of a large,
landscaped open space area referred to as Legacy Park. The development of Legacy Park included the
day lighting of a significant length of a previously piped section of the Koromatua Stream and the
significant enhancement of the stream through construction of a series of on-line pond features and
riparian plantings.
With the Stage 1 development activities now nearing completion, the Applicant is considering the future
development of the balance site area (referred to as Stages 2 and 3 for the purpose of this report) which
will include areas of senior housing, general residential development, a localised area of commercial
development and additional areas of open space land extending from the existing Legacy Park
development. It is the earthworks and stormwater diversion and discharge activities within the Stage 2
and 3 development areas which are the key subjects of these applications.
In addition, it has been identified that a number of boardwalk/bridge structures that have recently been
constructed across the newly opened section of the Koromatua Stream as part of the Stage 1 Legacy
Park development activities, are unable to comply with the permitted activity standards of the Waikato
Regional Plan (WRP). Hence, while it is considered that these structures have/will not result in any
adverse effects on the Koromatua Stream channel or surrounding land, retrospective consent is also
being sought to authorise these structures through these applications.
2.2
Site Description
The former Church College Campus is located in Temple View, approximately 2km to the southwest of
the Hamilton City residential suburb of Dinsdale. The former campus buildings and facilities sit upon the
gentle gradient eastern slopes of the Tuhikaramea Road ridgeline which runs through the centre of the
township. At the base of this slope the topography transitions into flat peat lands which stretch
eastward, encompassing the existing campus playing fields, tennis courts and service buildings and then
open pasture land used for dairy farming.
In addition to the former Church College site development activities, the subject applications include a
proposal to borrow fill material from another nearby site owned by the applicant comprising an
elevated area of pasture land used for dairy grazing located directly southward of the Mormon Temple.
Both sites are located within the jurisdiction of Hamilton City Council and are subject to a specific
Temple View Special Character zoning under the Proposed Hamilton City District Plan.

The entire site area and all of the land between the development area and the borrow site is held within
the applicants ownership. Additionally, the majority of land surrounding the site including the upstream
and downstream Kotromatua Stream catchment areas are also held within the applicants ownership as
outlined upon the LDS Land Ownership Plan included within Appendix C of the AEE.
As described, the southern portion of the former Church College site is currently subject to the
previously approved Stage 1 development works which to date has included the following activities:

Construction of the large Stake Centre chapel facility and associated access roading and
carparking;

Installation of stormwater infrastructure including a large wetland swale, six rain garden
devices and a large on-line attenuation pond;

Diversion/daylighting of a previously channelised/piped section of the Koromatua Stream to
flow through the large on-line pond device which has been subject to significant landscaping
and riparian planting; and

Upgrade of the Tuhikaramea Road carriageway and drainage system including installation of
enviropod catchpit filter bags to treat road runoff.
Figure 2 below provides an image of the previously piped section of the Koromatua Stream which is now
flowing through the on-line pond feature.
Doc # 9728472
Page 3
Figure 2. Recently constructed open section of the Koromatua Stream (previously piped)
The proposed Stage 2 and 3 future development areas will extend northward from the Stage 1 area
across the remaining balance area of the former Church College Campus covering an area of
approximately 24ha.
The site topography again comprises a gentle slope extending eastward from Tuhikaramea Road upon
which the remaining college buildings are located, which then transitions into the low lying, flat peat
lands which contain the former school playing fields and open spaces. There is no notable vegetation
within the site with site coverage limited to either the former college buildings and access ways or
maintained grass surfaces.
It is noted that part of the site area (comprising the low lying open space area at the southern end of the
site) has already been subject to placement of large volumes of pre-load material which was excavated
and placed within this area as part of the Stage 1 works. These works, which are outside of the
consented Stage 1 works area, were undertaken with approval from the WRC compliance officer
following confirmation that they were compliant with WRP permitted activity provisions with the works
including construction of a large sediment retention pond (SRP1) along the eastern site boundary to
manage any runoff from this area.
2.1.1
Soil Contamination
Areas of soil contamination have previously been identified within the site comprising a historic landfill
within the eastern site along with isolated areas where oil tanks formerly used for heating of buildings
have been located. Remediation of these areas have been subject to previous consent processes with
both the WRC and HCC/WDC with works having been completed on site to remove contaminated
materials.
2.1.2
Site Drainage and Catchment Background
Site runoff generally occurs in an easterly direction, down the site slopes to the low gradient flats before
entering the Koromatua Stream which flows along the southern site boundary. More specifically, runoff
from the existing Church College development surfaces on the site slopes is collected in a reticulated
stormwater system and discharged via one of two outlets. A small catchment located within the
southern part of the proposed development area discharges via a recently installed piped network to a
recently constructed treatment swale device within which the upper portion of the swale is currently
Doc # 9728472
Page 4
being utilised as a temporary sediment retention pond (Swale SRP). For the remainder of the Stage 2
and 3 development area, discharges occur from the old college piped network via a 600mm outlet pipe
which extends eastward through the low lying open space area to discharge to an open farm drainage
channel which extends along the eastern side of the boundary conveying site runoff and adjacent farm
runoff along with groundwater flows southward to enter the main Koromatua Stream channel within
the recent Stage 1 stream diversion works area. This tributary drain comprises a constructed artificial
drainage channel draining a localised catchment at the northern end of the site with flows through the
drain reducing to minor seepage flows during the summer months.
The proposed earthworks borrow site comprises an elevated ridgeline/knoll feature with a pasture
cover which is currently used for dairy grazing. The old Temple View water supply tank farm is located
on the top of the knoll which will be subject to removal as part of the works. Runoff from the western
side of the ridgeline drains via an existing culvert under Tuhikaramea Road to enter an ephemeral
drainage channel which drains westward eventuating in the Kormatua Stream. Runoff from the eastern
side of the ridgeline drains to an open farm drain which extends northward from the site to enter the
Koromatua Stream, within the recent Stage 1 Legacy Park works area.
Upstream of the site, the Koromatua Stream drains a large catchment of around 966ha which generally
comprises the low lying peat flats surrounding Collins Road which have been converted to large scale
dairy farming operations through installation of an extensive land drainage network to lower catchment
groundwater tables. The majority of the catchment area comprises land in the ownership of the
applicant.
Through this upstream catchment, the stream channel is more characteristic of a constructed farm drain
following a lineal path along farm fence lines or raceways and with no riparian vegetation cover. Based
upon the low gradient topography and peat soils within the catchment, stream flows are largely dictated
by ground water levels as opposed to surface runoff during storm events.
As described, the stream channel through the site has been subject to significant recent enhancements
through construction of a large on-line pond features with large amounts of riparian planting to
maximise both the environmental and landscape values of the watercourse as it passes through the site.
The pond discharges via a new outlet weir structure to pass via twin 1200mm culverts under
Tuhikaramea Road. From the culvert outlet, the Koromatua Stream follows a more natural meandering
course flowing through open farmland again comprising land in the ownership of the Applicant for
approximately 700m downstream of Tuhikaramea Road. Beyond this point the stream continues to flow
westward to enter the Waipa River just upstream of Whatawhata.
The entire length of the Koromatua Stream has a Waikato Surface water classification under the
Waikato Regional Plan.
2.1.3
Ecological Values
Appendix I of the AEE contains an Ecological Assessment prepared by Kessels Ecology on behalf of the
Applicant including a description of the ecological values of the Koromatua Stream which included a
sampling location within the vicinity of the site. Key findings of this study in regards to the Koromatua
Stream receiving environment include:

Water quality within the stream is influenced by discharges from Lake Koromatua upstream of
the site which has previously been classified as hypertrophic (very high in nutrients). In turn,
water quality at the site is classed as being low due to these inputs plus the influence of runoff
from the broader agricultural catchment;
Doc # 9728472
Page 5

Macroinvertebrates are limited to communities indicative of soft bottomed, highly modified,
agriculturally impacted habitats being dominated by taxa tolerant of a wide variety of habitat
conditions;

Long fin and short fin eels were the only species caught at the site downstream of Tuhikaramea
Road with a previous study identifying species upstream of the road culvert limited to short
finned eel which may be attributed to both the poor habitat quality and a barrier to fish passage
presented by the existing steep concrete ramp at the outlet of the Tuhikaramea Road culvert;

Overall, ecological habitat values of the stream are considered to be low due to the highly
modified nature of the channel and lack of riparian vegetation.
2.1.4
Cultural and Archaeological Values
Preliminary investigations for the overall site development project have included an archaeological
assessment of the area to determine any archaeological values. The key findings of this investigation
include:

Oral history of the site from local iwi has outlined that a maori village was located within
the vicinity of the site, somewhere near the Foster Rd Chapel;

Six bodies were discovered during construction of the Temple in 1958 (outside the subject
site). A blessing was undertaken at this time and most of the bodies were relocated to
Taupiri urupa however at least one body was re-located within the temple grounds, being
buried near the existing Temple entranceway (outside of the proposed works);

The NZAA records do not include any registered archaeological sites within Temple View
(other than the 6 bodies which have now been added by the project archaeologist) and any
sites that were present have likely been destroyed during past development activities;

Investigations have been undertaken on the elevated, undeveloped land to the south of the
Temple comprising the proposed borrow site as this may have been favoured by maori and
does not appear to have been subject to past modifications. These investigations
discovered no archaeological features.
A copy of the Archaeological Report is included as Appendix J of the AEE.
2.2
Proposed Activities
As discussed above, the applicant is proposing to redevelop the former Church College Campus site for a
variety of different land uses. Specifically, the current applications relate to Stages 2 and 3 of the site
redevelopment which will comprise the following activities:

Development of a proposed senior housing area including approximately 100 senior
housing units, a central rest home facility and associated access roading and service
installations;

Development of a proposed residential housing area including approximately 166 private
residential housing lots and associated access roading and service installations;

Development of an approximate 700m2 commercial development area at the sites
Tuhikaramea Road frontage;
Doc # 9728472
Page 6

Development of a large, open space reserve area at the sites eastern boundary;

Construction of three stormwater treatment wetlands within the reserve land along the
sites eastern boundary; and

Diversion/enhancement of the existing artificial drainage channel running along the sites
eastern boundary to provide enhanced landscape and habitat functions.
These activities will require initial cut to fill earthworks to prepare the site for the proposed
development activities along with the installation of the new site stormwater management system to
dispose of runoff from the developed site surfaces. In addition, the application proposes to obtain
consent authorisation for the recently constructed boardwalk/bridge structures over the Koromatua
Stream which have been implemented as part of the Legacy Park/Stage 1 development works.
The activities which are the subject of these consent applications are described in detail in the following
sections.
2.2.1
Earthworks and Cleanfilling
The site development activities will require bulk earthworks activities to establish the future
development platforms and associated roading and service infrastructure. For the purposes of this
report, the proposed earthworks activities can essentially be split into three separate areas comprising
the main development area earthworks, the lower lying reserve area earthworks (comprising the
stormwater wetland and drain diversion construction activities), and the proposed farm borrow site.
The specific activities within each of these areas are described within the following sections and are
outlined in the Earthworks Plans contained in Appendix E of the AEE.
Development Site Earthworks
The development site earthworks comprise the cut to fill activities occurring across the main site slope
containing the former college buildings and access road network and extending eastward down onto the
initial lengths of the lower lying playing fields and open space areas. It is a key aspect of these
development site earthworks activities that they will occur in two separate stages referred to as Stages
2 and 3 within these applications.
Initial works are currently commencing within the Stage 2 area comprising removal of the existing
buildings in preparation for the planned development earthworks to be undertaken in this area over the
2016/17 summer season.
Upon completion of the building removal works, the bulk earthworks will commence comprising cutting
of material from the elevated slope within the Stage 2 area to establish the future building and roading
platforms through this area with the Stage 2 earthworks extending across an area of approximately
6.5ha. Cut material will be transferred directly to the lower lying flats to the east where it will be placed
directly onto the existing low gradient ground surfaces as engineered fill material. The engineered fill
platform will then be preloaded with additional material which will be imported from the proposed
borrow site down Tuhikaramea Road (refer below). The preloaded platform surfaces will then be left
and monitored to allow sufficient settlement to occur for the planned development activities. Based
upon previous experience from the Stage 1 works, a settlement period of approximately 12 months is
anticipated
Over this settlement period, development site earthworks will commence within the Stage 3
development area following a similar process as the Stage 2 works, commencing with cutting of material
from the elevated site slopes and placement of this material as engineered fill across the lower lying
Doc # 9728472
Page 7
development surfaces. The Stage 3 development earthworks extend across an area of approximately
13ha.
Upon achieving sufficient settlement within the Stage 2 area, the preload material from that area will
then be transferred directly onto the Stage 3 engineered fill surfaces to initiate preloading.
Within each development stage, once the design settlement requirements are achieved and the preload
has been removed, final works can proceed to trim the engineered fill surfaces to the design contours
and to install roading and service infrastructure.
The cut/fill plans attached within Appendix E Outline a maximum cut of 3m and a maximum fill of 2.5m
(excluding preload depths) within the development site earthworks area.
At the completion of the Stage 3 preload works, the preload material will need to be removed and will
comprise surplus material which will be disposed of as landscape fill within the open space reserve areas
within the eastern most parts of the site.
It is noted that as the proposed filling/preloading activities within the lower parts of the site will need to
occur directly across the existing topsoil/grass surfaces within these areas (for structural reasons), this
topsoil will be unavailable for spreading across the completed development surfaces upon completion
of the earthworks. Hence a need for importation of topsoil is anticipated at the completion of each
development stage.
Reserve Earthworks
The main earthworks activities to be undertaken within the open space reserve areas along the eastern
boundary of the site comprise the excavation and formation of three new stormwater treatment
wetlands and the diversion/enhancement of the existing drainage channel extending along this
boundary with these activities extending across an earthworks area of approximately 3.5ha within the
reserve land.
Stormwater Wetlands 2 and 3 will be constructed as part of the Stage 2 development activities whereas
the larger Wetland 4 will be constructed as part of the Stage 3 development works. Construction of each
wetland will essentially occur as a subsurface excavation to depths of around 1m with the wetland being
formed as a series of separate pools or chambers. A discharge outlet channel will also be formed as part
of these works to convey wetland flows to the adjacent eastern tributary drain. Material excavated from
each wetland will be incorporated as landscape fill within the adjacent development/reserve area.
It is also proposed to undertake works to enhance both the landscape and ecological values of the
existing outlet drain running along the eastern site boundary. These works will include the following
components:

Realignment of the stream to follow a more natural winding path (as opposed to the
current lineal alignment);

Daylighting of an approximate 100m long piped section of the existing drain to be restored
as open channel;

Formation of a trapezoidal shaped low flow channel with a wider, low gradient, battered
flood plain area which will be subject to inundation during high flows;

Stabilisation of the channel with coconut mat application to both minimise potential
channel erosion effects while allowing plants to establish within the channel;
Doc # 9728472
Page 8

Formation of the channel with a maximum 1% gradient to minimise flow velocities and to
maximise stormwater treatment within the channel; and

Planting of the entire length of the channel with native riparian/wetland species to provide
for channel shading and further biofiltration of stormwater.
Borrow Area Earthworks
The borrow area earthworks will comprise stripping of topsoil to access the underlying ash material
which will be mined as fill/preload for the development earthworks areas with these works extending
across an earthworks area of approximately 3.7ha.
The borrow excavations are intended to commence from the eastern side of the ridgeline with the
material being loaded directly into road trucks and hauled approximately 800m down Tuhikaramea
Road to the development site. In this respect an initial area of works within the borrow site will
comprise construction of a stabilised haul track to allow for truck access within the borrow site and out
on to Tuhikaramea Road.
Earthworks within the borrow area (including topsoil stripping) will occur progressively as fill is required
at the development site. As the design contours are achieved, the completed borrow areas will be retopsoiled and grassed and returned to grazing pasture.
In addition to the proposed borrow excavations within this area, a small area of filling is proposed within
the northern part of the site towards the Temple carpark which is proposed purely to tie the new
borrow area contours into the adjacent slope to maintain the aesthetics of this road frontage area.
Again the filling works will follow the same methodology of stripping of topsoil, placement/shaping of fill
and re-topsoiling/grassing.
The cut/fill plans attached within Appendix E outline a maximum cut of 3.5m and a maximum fill of 0.5m
within the borrow site earthworks area.
A summary of the anticipated earthworks activities to be undertaken within the three areas described
above is summarised in Table 1 below.

Over the duration of the earthworks period, erosion and sediment controls will be implemented on site
to ensure that potential erosion and sediment effects are appropriately controlled. These controls will

Page 9
be implemented in general accordance with the Waikato Regional Council Technical Report Erosion and
Sediment Control Guidelines for Soil Disturbing Activities, January 2009 (TR2009/02). More specifically,
erosion and sediment controls will be implemented on site in general accordance with the Erosion and
Sediment Control and Dust Management Plan included as Appendix F. Additionally, dust control
measures will be implemented throughout the works in accordance with this plan.
The Stage 2 and Borrow Area earthworks are intended to commence in January, 2017 and will be
completed over the summer 2016/17 earthworks season. The Stage 3 earthworks are intended to
commence within the following 2017/18 summer season with all earthworks activities intended to be
completed by the end of 2018.
2.3.2
Stormwater
The development of the site for the planned residential and commercial landuse activities will result in
the creation of new impervious surfaces including buildings, roading, carparks and other hard stand
areas from which runoff will be captured and conveyed, via appropriate stormwater management
systems, to discharge points within the adjacent watercourses. The philosophy behind the proposed
stormwater design is based upon the management of potential downstream water quality and quantity
effects to ensure that potential effects from new development surfaces within the Koromatua Stream
are no more than minor. In this respect the proposed design has been developed to achieve the
following stormwater management objectives:

Treatment of all stormwater runoff from new contaminant generating surfaces (e.g
roading/carparking) in accordance with best practice;

Attenuation of stormwater runoff as required to ensure that post development discharge
rates do not exceed those of the current discharge scenario and potential downstream
flooding and erosion effects are avoided.
The specific features which have been incorporated into the drainage design to achieve these stormwater
management objectives are outlined in detail on the design plans and within the Sub Catchment Integrated
Catchment Stormwater Management Plan (SMP) included within Appendix G of the AEE. It is noted that
the scope of this SMP extends to the stormwater management provisions across the entire Church College
re development site and in this respect, covers the previously approved details relevant to the Stage 1
wetland swale, raingardens and on-line attenuation pond devices.
Considering the provisions of this SMP relevant to the subject Stage 2 and 3 development areas, the
following stormwater management features are proposed to manage any potential stormwater runoff
effects both within the site and downstream of the proposed development areas:

Collection of stormwater runoff from the development surfaces within a piped reticulation
network draining eastward through the site towards the existing tributary drain. The
reticulation network is sized to convey flows up to the 1 in 10 year design storm with any flows
in excess of the networks capacity being conveyed as overland flow, typically along the
development road carriageways;

Discharge of stormwater runoff from the Stage 2 and 3 reticulation network to one of three
proposed stormwater treatment wetlands incorporating the following design measures to
maximise treatment function:
 The inlet pipe to each wetland will discharge into an initial sedimentation chamber
comprising a prefabricated concrete chamber for capture of gross contaminants and to
provide a location for routine maintenance with a sucker truck. Each chamber will also
incorporate a bypass pipe for conveyance of larger flows;
Doc # 9728472
Page 10
 Discharges from the chamber to occur via an outfall structure into a wetland forebay;
 The main body of each wetland to comprise three wetland pool/chambers which in
combination will have enough volume to contain the entire water quality storm as defined
within Auckland Councils Technical Publication 10 Stormwater Management Devices:
Design Guidelines Manual, May, 2003 (TP10). By capturing and containing the entire water
quality volume, treatment can be achieved without the need for a concrete outlet control
structure which would have the tendency to sink within the local saturated peat soils in
the reserve areas. The calculated water quality volume and proposed wetland volume for
each of the Stage 2 and 3 devices is summarised in Table 2 as follows:

 Minimum of 80% of each wetland body and the surrounding area to be planted with native
wetland plants;
 Discharges from each wetland to occur via overflow of a stabilised broad crested outlet
weir to a constructed outlet channel to the adjacent tributary drain.

Discharges from each of the wetlands to be conveyed via the tributary drain (which is to be
subject to upgrade/enhancement works) to the recently constructed Koromatua Stream online attenuation pond device within Legacy Park. This device (previously approved by WRC)
has been designed to ensure that post development discharge rates for the entire Church
College redevelopment activities do not exceed predevelopment levels.
The SMP has included modelling of the pre and post development runoff scenarios for the entire
development area to determine the impact of site redevelopment on stormwater hydrology and pond
design requirements. This modelling has indicated that based upon the ‘brownfields’ nature of the
proposed site redevelopment, the activities will not result in significant increases in total impervious
surfaces and subsequently the rate/volume of stormwater runoff from the current scenario which currently
occurs in an un-attenuated manner. Hence attenuation requirements for the re-development proposal are
considered to be of a relatively minor nature and based upon the proposed stormwater management
measures has in fact indicated a net reduction in post development flows discharging from the Tuhikaramea
Road culvert to the downstream environment.
Preliminary plans outlining the proposed stormwater reticulation network, wetland design and existing
attenuation pond design along with design parameters used for these devices are included within the SMP
attached as Appendix G of the AEE.
The longterm ownership and maintenance responsibilities for most of the stormwater assets constructed
for the Stage 1 development activities including the on-line attenuation pond and rain garden devices are all
to be retained with the consent holder/LDS. This is on the basis that the Stake Centre chapel, car parking
area and the surrounding Legacy Park reserve area (which incorporates the pond devices) and associated
drainage systems are all to be retained within the private ownership of the LDS and hence private
management of these systems is justified.
Doc # 9728472
Page 11
For the Stage 2 and 3 development areas, the majority of the site development catchment will comprise the
future residential development lots and road services and hence it is considered to make more sense that
the drainage system and associated stormwater management measures are vested with HCC as public
assets. Subsequently it is the intention that the piped reticulation network, the sedimentation chambers,
the wetland devices (up to the 10 year event water level), the wetland discharge outlet and the outlet drain
to the Koromatua Stream will be vested with council as public assets. Ownership and maintenance of the
surrounding open spaces/park lands will be maintained with the applicant.
2.3.3
Bridge and Boardwalk Structures
As part of the Stage 1 Legacy Park development activities, a number of structures have been constructed
which extend across/within the bed of the newly constructed open sections of the Koromatua Stream.
The structures include a larger pedestrian footbridge constructed across the recently formed stream
channel section at a narrow point just upstream of the main attenuation pond body to provide a pedestrian
connection between the Stake Centre chapel and the Mormon Temple. This bridge comprises a single span
steel beam/timber deck bridge with a span between the bridge abutments of approximately 12m. The
bridge has been designed/constructed so that the bridge has a soffit level of RL 37.64m sitting directly
above the 1 in 100 year stream flow level of RL 37.6m as specified within the SMP.
Additionally, an extensive boardwalk network has been constructed extending around the margins of the
upper most Koromatua Stream ponding area, also crossing the channel at three separate points. These
include at the upstream point where the Koromatua Stream enters the site, across the northern tributary
drain channel where it connects into the upstream end of the Koromatua Stream online pond system and at
a narrow pinch point part way through the recently constructed open channel section. The boardwalk
structures have been constructed using treated timber piles extending directly into the stream/pond bed
and with a low level treated timber deck with corten steel edging and corten steel balustrades at the
locations where the board works crosses the deeper channel sections. On this basis, the boardwalk
structures have been designed to overtop during larger catchment flow events without posing any
significant impediment to the low gradient catchment flows.
The location of the existing boardwalk/bridge structures constructed during the recent Stage 1 works is
outlined in Figure 3 below with the detailed design plans of these structures included within the
Bridge/Boardwalk Design Plans included within Appendix H. Additional photos of the completed structures
are included within the Site Photo Record contained within Appendix D of the AEE.

Status of Activities under the Plans
The consent activities applied for are regulated through the Waikato Regional Plan (WRP). The WRP
became operative on 28 September 2007 therefore no other plans apply. The status of the activities
under the WRP are described below:
3.1
Earthworks
Neither the proposed Stage 2 and 3 development site or the borrow area are considered to comprise a
‘high risk erosion area’, as defined under the Waikato Regional Plan. Nonetheless, the works are
significant in scale and the earthworks activities will be subject to the conditions of Rule 5.1.5 with
condition (h) requiring adherence to a suspended solids discharge standard of 100 grams per cubic
metre throughout the works. While implementation of best practice erosion and sediment control
measures is proposed over the duration of earthworks, strict adherence to this standard cannot be
guaranteed during a significant rainfall runoff event. Hence, to allow for any unforeseen breaches of
these standards, resource consent authorisation is thus being sought as as a discretionary activity under
rule 5.1.4.15 of the WRP.
It is acknowledged that the Stage 2 and 3 development activities will involve the importation and
placement of both preload material and topsoil from outside of the direct boundaries of the
development area. Nonetheless, the sources for these materials will likely be from within the broader
LDS land holdings and will be limited to cleanfill soil materials only and hence will not result in the
introduction of contaminated or leachable materials to the site development area. The large scale
disposal of cleanfill materials outside of a high risk location (as is the case at the site) is to be considered
as a controlled activity in accordance with rule 5.2.5.5 of the WRP.
In this instance, it is considered appropriate that based upon the low risk nature of the cleanfilling
activities, consideration of any relevant effects occurs under the discretionary provisions of the
proposed land disturbance/earthworks application.
3.2
Stormwater
While the proposed Stage 2 and 3 development areas include existing development surfaces,
stormwater reticulation and a discharge to the Koromatua Stream, the catchment will be subject to
significant re-development activities including installation of new stormwater reticulation and new
discharge outlets. The discharge of stormwater from the redeveloped site will occur from an urban
catchment area in excess of 1ha (approximately 24ha) and thus cannot comply with WRP permitted
activity requirements. The activity thus requires resource consent authorisation as a discretionary
activity pursuant to rule 3.5.11.8 of the WRP.
3.3
Boardwalk/Bridge Structures
Rule 4.2.8.1 of the WRP permits new bridge structures where they do not exceed a single span length of
10m and where the soffit (underside of the bridge beams) is at least 0.5 metres higher than the top of
the banks of the river bed, or at least 0.5 metres above the 1 in 50 year flood level, whichever is the
lowest.
Considering the recently constructed pedestrian bridge, the bridge is noted as having a single span
length of approximately 12m and thus is unable to comply with the above permitted activity standards
in relation to a maximum 10m span length. Furthermore, while the bridge soffit level is established as
being above the 1 in 100 year flow level, the design level is still unable to meet the above standard in
relation to 0.5m clearance above the 1 in 50 year level with this level specified within the SMP at RL
37.42m and with the bridge soffit located at RL 37.64m (i.e only 0.22m clearance of the 50 year flow).
Doc # 9728472
Page 13
Considering the recently constructed boardwalk stream channel crossing structures, these structures
have been identified as being constructed with a soffit level which is just above the typical winter flow
level with these structures designed to overtop during larger winter flows, with overtopping having
already occurred twice over the 2016 winter period.
In this respect, the boardwalk structures are unable to comply with both the permitted (rule 4.2.8.1) and
controlled (4.2.8.2) activity standards in relation to maintaining a soffit level above the top of the banks
of the river bed, or at least 0.5 metres above the 1 in 50 year flood level. Bridge structures which are
unable to comply with these standards are to be considered as a restricted discretionary activity in
accordance with rule 4.2.8.3 of the WRP.
It is acknowledged that the bridge/boardwalk structures were constructed unintentionally without the
necessary resource consent authorisations during the Stage 1 development works. Hence, the consents
sought for these structures are accordingly acknowledged as being of a retrospective nature.
3.4
Other Consents
Drain Diversion
As the existing drain running along the eastern site boundary, which will be subject to diversion
activities, comprises an artificial farm drainage channel with a catchment less than 200ha (being
approximately 20ha), the proposed diversion activities are considered to be provided for as a permitted
activity in accordance with rule 3.6.4.8 of the WRP. Nonetheless, any potential effects of undertaking
these diversion activities are addressed within the earthworks section of the assessment of effects
outlined in section 8 of the AEE.
Hamilton City Council
Consent authorisation is required from the Hamilton City Council under the district plan for a variety of
activities associated with the proposed Stage 2 and 3 development activities including the Church
College building removals, construction earthworks and eventual subdivision activities.
To date, land use approvals have been obtained to authorise the building removal and construction
earthworks activities within the Stage 2 development area only. Additional land use consents for the
Stage 3 works and the eventual subdivision consents for the new development lot creation will be
pursued at a later date once further design details are known. However it is notable that the proposed
development activities are in keeping with the Temple View Special Character zoning under the
Proposed Hamilton City District Plan and are anticipated by HCC.

4.1
Consultation/Affected Party Approvals
Iwi
Significant consultation has been undertaken with local iwi group Ngati Mahanga including several site
visits to ensure that they are kept informed of the proposed site developments.
During this consultation, iwi have previously outlined the discovery and relocation of six bodies during
excavations associated with construction of the Mormon Temple in 1958. They confirmed that bodies
relocated within the temple grounds were placed in graves on land adjacent to the existing temple
entrance road and were marked by planting of fan palms. The grave location is outside the boundary of
the proposed works.
No further items of cultural or spiritual significance have been identified by local iwi to date and on this
basis, development activities have proceeded on site with no cultural/spiritual concerns. Consultation
has again been undertaken with Ngati Mahanga in relation to the proposed development stages with no
Doc # 9728472
Page 14
concerns being raised during preliminary discussions. Copies of the development plans have also been
forwarded for comment and a copy of any comments received will be forwarded to the WRC.
4.2
Other Parties
Hamilton City Council
Significant consultation has been undertaken with Hamilton City Council (HCC) throughout the design
process to ensure that they are aware of the proposed developments activities and are agreeable to the
proposed infrastructural design particularly in regard to any assets which may be vested with HCC for
long term operation and maintenance responsibilities. It is noted that through consultation undertaken
to date, HCC have outlined a preference that all of the proposed reserve areas within the site are
retained and maintained by the applicant rather than be vested with Council to avoid the
responsibilities and costs associated with these areas.
Consultation with HCC will be ongoing throughout the detailed design phase and implementation of the
works will be undertaken in accordance with all requirements of HCC as specified through their consent
conditions.

Assessment of Environmental Effect
Having considered the nature of the proposal and the supporting information provided with the
application, the actual and potential environmental effects to consider are those relating to:







6.1.1
Water quality effects from sediment discharges during earthworks;
Local air quality degradation from dust discharges;
Exotic weed invasion;
Archaeological and cultural effects.
Catchment hydrology and water quality and quantity effects from stormwater discharges post
development;
Hydraulic effects of bridge/boardwalk structures; and
Ecological effects of the bridge/boardwalk structures.
Water Quality Effects from Sediment Discharges during the Earthworks
Soil disturbance activities increase the potential for erosion and destabilisation effects and have the
potential to discharge sediment into waterways both during and after the works until the ground
surface is stabilised. Sediment discharges to water can cause a range of adverse effects on fresh water
ecosystems, including smothering aquatic life, damaging fish and invertebrates’ gills, destruction of
spawning grounds, and the deposition of nutrients to waterways. Increased turbidity can interfere with
aquatic animal’s abilities to feed due to poor visibility and reduced light penetration can reduce
photosynthetic activity.
Although the site is relatively flat, the proposed bulk earthworks to place fill, construct the wetlands and
expose soil as part of the site preparation has the potential to discharge sediment during rain events
into the surrounding drainage networks and eventually into the Koromatua Stream if proper sediment
and erosion controls are not in place.
The applicant has provided an ‘Erosion and Sediment Control Plan’ (ESCP) as prepared by Bloxam
Burnett & Olliver Ltd, which outlines the high level concepts that will be undertaken to control and
mitigate any potential adverse effects from earthworks activities. The ‘Erosion and Sediment Control
Plan’ has been assessed by Waikato Regional Council (WRC) staff, who consider that the plan has been
prepared in general accordance with WRC’s publication, ‘Erosion and Sediment Control – Guidelines for
Soil Disturbing Activities, January 2009’. The ESCP contains sufficient detail to enable Stage 2
development works (including the burrow pit area) to be undertaken within this upcoming 2016/17
earthworks season. The intention is to provide an updated ESCP for the future Stage 3 development
works prior to their start, however it is considered that the current ESCP has enough detail to enable a
preliminary assessment at this time. A condition of consent has been included in the attached resource
consent certificate to this affect.
The applicant is proposing to utilise the existing erosion and sediment control devices on site as well as
incorporating the proposed stormwater wetland excavation ponding areas which will act as SRP devices
during the construction period.
Stage 2
The applicant has divided the Stage 2 works into 2 sub-catchments. The smaller existing catchment of
1.2 ha located at the south western corner of the site has existing drainage and the future earthworks
runoff going to an existing swale SRP which was recently formed to treat runoff from this catchment
area. The swale SRP has been previously approved by WRC staff and has been oversized for this
contributing catchment with a volume of 421 m3 being 3.5% of the catchment.
The second sub-catchment is the balance of Stage 2 which comprises the lower part of the area with
much of it already exposed as part of the pre-loading activities associated with Legacy Park and
Doc # 9728472
Page 17
approved by WRC staff. An existing SRP (SRP 1) has been constructed at the eastern boundary of the
site. The SRP 1 has a design catchment of 3.8 ha with a volume of 761 m 3 and the applicant proposes to
continue to make use of SRP 1 as the main treatment device for the Stage 2 earthworks. However, due
to cutting activities proposed on the lower slopes along with filling/pre-loading extending across the
lower site, the catchment area will increase to 5.97 ha. Therefore, the applicant is proposing to use the
future excavated stormwater wetland ponds (Wetlands 2 and 3) footprint areas, to be located either
side of the current SRP 1, as additional storage volume for treatment. Any discharges from these
excavations will be configured to ensure they overflow to the SRP 1 forebay only. This is considered
acceptable to WRC staff.
The applicant is proposing to strip topsoil from the site to establish perimeter bunding around each
stage of works to prevent clean water entering the works areas and will divert all sediment laden runoff
to the treatment devices discussed above prior to discharging into the outlet drain.
The proposed earthworks associated with the drain diversion and enhancement works will consist of
damming and diverting methodology for each stage of the drain enhancement works. Sandbags or
compacted aggregate are proposed to be positioned across the drain at the southeastern corner of the
playing fields. Catchment flows are to be pumped around the works area to create a dry working area
with provision for a Decanting Earth Bund (DEB) at the base of the works for treatment of runoff. Works
will take place during the summer low flow conditions and will commence from the upstream end
working downstream to minimise disturbance. As sections are completed the sides will be stabilised
with pinned coconut matting or mulch. Upon completion the temporary dam structures will be
removed to liven flows through the new channel.
The applicant is proposing to undertake the Borrow Area works as part of the Stage 2 works. The
Borrow Area is to be divided into 2 separate catchments along the ridgeline running through the centre
of the site. Topsoil is to be stripped and used as perimeter bunding and an SRP constructed at the low
point for each catchment to treat all runoff before discharging to the downstream receiving
environments.
The applicant has considered the use of flocculants for the Borrow Area of works. However, considers
that based on the low gradient nature of the other stages of the site and the experience with the white
soils within the site, it is unlikely that provision of flocculation treatment will be required for Stages 2
and 3. However, the applicant will use flocculation as a contingency if required. I have included a
condition of consent in the attached certificate requiring the applicant to undertake bench testing of the
soils to determine the effectiveness of flocculant treatment prior to bulk works commencing at the
Borrow Area. If the bench testing results determine the soils suitable, a Flocculation Management Plan
shall be prepared by a specialist consultant and submitted for approval prior to the commencement of
bulk earthworks. I have also included a further condition of consent in the attached certificate to this
affect.
Stage 3
The proposed Stage 3 earthworks will comprise the largest stage of works on the site at 15.3 ha. It is
expected that the works will again be relatively straight forward and will be managed through a similar
methodology as discussed for the Stage 2 works.
It is proposed that topsoil will be stripped from the site in various sub-stages of development and used
as perimeter bunds or stockpiled. All stockpiles will be located within SRP catchment boundaries.
The excavation of Wetland 4 in the north eastern corner of the site will then be undertaken as this will
act as an interim SRP for the entire Stage 3 earthworks. Based on using the WRC guideline criteria of a
3% SRP volume for the contributing catchment, a volume capacity of 4500 m3 would be required.
However, the proposed volume of the excavated wetland area has a design volume of 2443 m 3 which is
2000 m3 short to meet the SRP guideline criteria. The applicant considers that given the nature of the
Doc # 9728472
Page 18
large earthworks catchment with a long low gradient over flat surfaces which will allow adequate
potential for sediment to drop out before reaching the Wetland 4 SRP. Again, this has been discussed
with the WRC Earthworks Monitoring Officer for the site who is comfortable with this proposed
methodology given his experience with the Stage 1 earthworks associated with the site.
The applicant is proposing a number of additional measures such as silt fencing, contour drains, drop
structures, settlement pits , and additional excavation for additional SRP volume as contingency
measures as part of Stage 3 works. These will be discussed in more detail as part of the detailed ESCP to
be submitted prior to the Stage works commencing.
Provided the proposed soil disturbance activities are undertaken in accordance with the Waikato
Regional Council publication ‘Erosion and Sediment Control Guidelines for Soil Disturbing Activities,
January 2009’, and as per the ‘Erosion and Sediment Control Plans’ for each stage of works as the
development progresses, I consider that the actual and potential adverse soil disturbance effects will be
temporary and no more than minor. I have also recommended a series of conditions to minimise and/or
avoid adverse effects on water quality including the implementation of additional erosion and sediment
control measures. It should be noted that ultimately the success of any erosion and sediment controls
will require comprehensive planning and regular inspections and maintenance of sediment/erosion
control devices.
To avoid fuel discharges entering any downstream water body during the proposed works, conditions
have been included requiring that all machinery is operated in a manner which ensures spillages of fuel,
oil and similar contaminants do not eventually enter the downstream Koromatua Stream.
6.1.2
Local Air Quality Degradation from Dust Discharges during Earthworks
Sites where ground cover is removed and soil disturbed have the potential to discharge dust. The
severity of dust discharges are determined by factors such as wind strength, soil type, size of area
exposed and moisture content of soil.
Some of the adverse effects, which can result from dust discharges include:




Potential health effects from breathing dust particles.
Nuisance effects, which can result from dust settling on surfaces such as cars, houses and household
washing.
Visibility effects, which can result from dust clouds moving offsite.
Effects on plants, which can result from dust deposits. These effects can include reduced palatability
of pasture and reduced photosynthesis due to reduced light penetration.
The applicant has identified that that although they own the majority of the surrounding land which is
primarily rural, there is a residential subdivision on the western side of Tuhikaramea Road and therefore
there is potential for adverse effects to occur.
As a result, the applicant has prepared a Dust Management Plan (DMP) included in Appendix F of the
AEE. The plan includes specific dust suppression mitigation measures such as:

Staging of earthworks – it is noted that while the entire earthworks area is significant the entire area
will not be open at any one time with the works likely to be undertaken in a number of much
smaller, separate sub-stages over a number of years;

Progressive stabilisation of earthworks – the majority of the proposed earthworks are considered to
be reasonably straight forward and should happen quickly with completed surfaces being
progressively stabilised as the design contours are achieved;
Doc # 9728472
Page 19

Control vehicle/machinery usage – restricting speed on site, locating haul roads appropriately,
stabilising haul routes if necessary, covering trailers and ensuring all vehicles are clean prior to
exiting the site;

Monitoring dust risk – close monitoring of weather forecasts to anticipate any dry/windy conditions
and programming works appropriately over these periods to minimise dust mobilisation;

Dust suppression – provision of watercarts on site to suppress dust in the event that dry/windy
conditions are anticipated. Suitable water supply options are available at the site for this purpose;

Contingency dust control – ceasing works or application of immediate dust suppressant products
including polymer, hydroseed or similar as required;

Targeted dust control – intensification of dust control methods when working in proximity to any
sensitive receivers.
I consider that provided the proposed dust mitigation measures are implemented as per the DMP
discussed above then the potential adverse effects of dust discharges will be temporary and no more
than minor. I have included a condition in the attached consent to this effect.
6.1.3
Exotic Weed Invasion
The proposed earthworks and vegetation clearance will provide conditions for invasive weeds to
become established on exposed surfaces during and after construction. Machinery brought onto the
site to undertake earthworks and vegetation clearance could potentially carry plant matter and/or
seeds, which could result in the introduction of new weed species in the area. This is a potential
detrimental impact as weeds may threaten the ecological integrity of the surrounding indigenous
vegetation. I recommend that all machinery brought onsite is first cleaned to remove any plant matter
and/or seeds. I have proposed a condition of consent in the attached certificate regarding washing of
machinery. On this basis, I consider that the risk of exotic weed invasion will be adequately avoided.
6.1.4
Cultural and Archaeological Effects
As previously described, there are no registered archaeological sites located within the proposed Stage
2/3 development area. Nonetheless, the historic discovery of bodies during construction of the Mormon
Temple and references to a maori village having been located within the vicinity of the site creates the
potential for further discoveries during site development. Thus, it is considered appropriate that should
historical artefacts or koiwi be discovered over the course of the proposed earthworks activities,
appropriate procedures and protocols are followed including notification of local iwi and the New
Zealand Historic Places Trust and ceasing all works in the vicinity of the discovery until they have been
removed.
Furthermore, local iwi group Ngati Mahanaga have been consulted extensively throughout the previous
development stages and for the current stage of works with no specific cultural or spiritual concerns
being raised.
Waikato Regional Council has standard consent conditions relating to circumstances where unidentified
archaeological sites are discovered. I consider that these conditions will ensure that appropriate
procedures/protocols are followed. In the event that previously unidentified archaeological sites are
discovered and not covered under the HNZ General Authorisations, there may be requirements for
further General Authorisations imposed by the HNZ. The inclusion of these conditions does not
preclude the use of other protocols if agreed between the applicant and iwi, however, they do provide a
minimum standard to be followed.

6.1.5
Catchment Hydrology and Water Quality Effects Post Development
Urbanisation, development of greenfield site areas and the way in which stormwater management is
incorporated into the design of developing catchments, will significantly influence catchment hydrology
in the post development situation. Essentially it is the loss of pervious surface area and the piping of
stormwater to surface waters that result in reduced rates of groundwater infiltration and recharge, and
greater volumes of runoff being discharged from developed catchments. These changes often result in
the lowering of groundwater tables, extreme dry and wet weather flow fluctuations in surface waters,
and an overall limiting effect in the ability of surface waters to support aquatic life.
In addition to these effects, increased stormwater volumes and peak rates of discharge can result in
adverse flooding hazards, stream channel scouring and erosion and diminished receiving water health
through reduced ecosystem viability, habitat availability and downstream sedimentation effects. These
effects are particularly common in urban catchments that have inappropriately designed stormwater
management systems, or no particular management system (the widespread historical situation in
existing urban catchments).
Stormwater runoff from roads and impervious areas are known to contain contaminants such as metals,
hydrocarbons and sediment. A number of these contaminants, if allowed to enter the environment, will
accumulate in the sediments of the receiving environment and may reach levels that are toxic to biota.
The highest potential source of contaminants from roading surfaces are heavy metals and hydrocarbons
from tyre/brake wear, exhaust fumes and fuel/lubricant leaks onto road surfaces. Other catchment
contaminants can include gross pollutants (i.e rubbish) and sediments from associated development and
sports fields as well as nutrient input from gardening/landscaping activities and possible sewer
overflows/illegal connections. As contaminants often become attached to sediment particles, removal
of suspended sediment provides partial treatment of stormwater.
As discussed in Section 2 of this report, the applicant is proposing to manage stormwater in accordance
with the document titled ‘Sub Catchment Integrated Catchment Stormwater Management Plan (SMP)December 2015’ included within Appendix G of the AEE.
Environmental Engineer Ms Megan Wood (Wainui Consulting Ltd) has undertaken an assessment of the
stormwater management design on behalf of Waikato Regional Council and provided a comprehensive
analysis of the proposal below (technical report dated 19/12/16 doc ref# 9727592).
Water Quality
Ms Wood has reviewed the proposed water quality treatment design and considers that with the
inclusion of sedimentation tanks, 80% wetland planting and storage of the full water quality volume, the
wetlands are considered to have been designed to provide water quality treatment in accordance with
TP10.
Water quantity
The SMP has included modelling of the pre and post development runoff scenarios for the entire site.
Due to the relatively developed nature of the pre-developed scenario, the proposed re-development
activities do not result in significant increases in total impervious surfaces above which were currently
there, hence attenuation requirements for the re-development proposal are not significant. The
proposed stormwater management measures result in a net reduction in flows to the Tuhikaramea
Stream when comparing post to pre-development scenarios for the 2, 50 and 100 year ARI events.
Channel erosion
Generally the channel forming flows are the smaller, more frequent rain events like the 1.5 and 2 year
ARI events. The impacts of development are generally from higher peak flows and longer duration of
peak flow. The hydrographs for the Koromatua Stream catchment have been compared for the pre and
Doc # 9728472
Page 21
post development conditions at the Tuhikaramea Road culvert outfall (section 7.2 of the Temple View
SMP). Comparison indicates little change in the hydrographs, with the modelled peak flow reduced and
the overall peak flow duration estimated to increase by 0.5hr – which does not constitute a significant
increase.
Analysis
Hydrologic and hydraulic models have been developed by the applicant using EPA SWMM-5 a USEPA
software package that allows dynamic wave routing for reticulated system design and estimating the
effectiveness of water quality treatment devices. The applicant has used SWMM to estimate and route
stormawter flows, size reticulation, and to develop the outlet characteristics and storage relationship of
the four ponds.
Ms Wood considers the SMP demonstrates that the overall effect of the proposed site re-development
on the hydrology of the Koromatua Stream downstream of Tuhikaramea Road is less than minor.
6.1.6
Hydraulic Effects of Bridge/Boardwalk Structures
If not appropriately designed, bridge/boardwalk structures have the potential to hinder flows during
flood events, causing water to back up behind the structures leading to flooding of upstream and
surrounding land. However, as discussed the applicant owns all the surrounding land and therefore any
adverse effects of flooding would all be on the applicant’s land.
Ms Wood has also undertaken an assessment of the structures in terms of their potential hydraulic
effects which is discussed below.
Boardwalk
As previously discussed, the boardwalks have been designed to overtop during larger catchment flow
events without posing any significant impediments to the low gradient catchment flows.
The boardwalk has been designed to have a deck level only just above the normal stream flow levels.
The boardwalk comprises pile structures, a deck level and steel balustrades at stream crossing points
which could present impediment to catchment flows resulting in backwater flooding effects and
potential damage occurring to the structure and the stream/pond.
The stream crossing points are the main location where issue could arise, this is at three locations. The
application states that the deck level has been set at RL36.5m, only 0.5m above typical flow levels. At
this level the structures are located within the 2 year flood levels and have been observed to be
inundated twice during the 2016 winter period. The balustrades extend 1m above deck level hence
could capture debris.
The applicant advises the boardwalk design engineers have confirmed that the structures have been
designed in accordance with best structural engineering practices with deep pile and secure fixings to
avoid structural damage or mobilization of components during flood events.
The boardwalk has been designed to allow for overtopping during flood events. The applicant notes
that there are several upstream farm culverts which would throttle flows before they arrive at the site.
Hence during flood events, flood flows which exceed channel capacity would already occur as wide
spread, low velocity inundation of the surrounding pasture as flows back up behind the various instream
structures or channel blockages. This type of flood progression is unlikely to cause damage to the instream structures. The applicant also notes that debris flow is unlikely due to the upstream land uses.
Based on the information provided by the applicant, Ms Wood considers that the potential hydraulic
effects associated with the boardwalk are considered to be no more than minor.
Doc # 9728472
Page 22
Bridge
The bridge has a clearance above the predicted 100 year ARI flood level of 40mm. Ideally a larger
clearance would be provided above the 100 year flood level to allow for debris flow, however in the
case of this site, it is a fairly small upstream catchment comprising predominantly farm land hence
debris shouldn’t be too much of an issue. The bridge will be a private asset and if any problems
manifest the applicant will need to manage them.
As noted in the application previously the stream was piped for 250m, hence the daylighting of the
stream and provision of a bridge is a significant improvement on the pre-developed stream condition.
Based on the information provided by the applicant, Ms Wood considers that the design of the bridge
structure is considered acceptable.
6.1.7
Ecological Effects of Bridge/Boardwalk Structures
The constructed bridge/boardwalk structures are located within the recently constructed stream
channel section which previously combined either a straightened drainage channel or piped channel
section. As part of the previous Stage 1 works, the applicant ‘day lighted’ this channel section by
replacing it with a large on-line pond structure which is subject to extensive riparian planting to
maximise both landscape and habitat values resulting in significantly enhanced ecological values than
the pre-development drainage system.
The new pedestrian bridge structure is elevated well above stream flows with plantings extending
directly up tot eh bridge on all channel sides. The boardwalk structures include piles directly within the
flows at approximately 1.5 m spacings. However the structures are not considered to be creating any
adverse effects upon stream ecological values with fish passage being maintained through the site and
with the entire stream channel area upstream and downstream of the structures being subject to
riparian plantings.
Koromatua Stream Enhancement
The applicant is currently proposing a number of future enhancements of the Koromatua Stream
catchment which will include:



Stream enhancement works in two separate stages: Stage 1 - Lake Koromatua to Legacy Park,
1.5km, 2017 and Stage 2 – Tuhikaramea Road to Wood Road, 1.2km, timing TBC;
Channel modifications including floodplain cut outs, bank battering and realignment to increase
channel morphology/sinuosity;
Installation of channel habitat enhancement and erosion protection measures such as root
wads, woody debris and artificial habitat enhancement measures; and
Riparian planting and fencing to maximize channel stabilisation and habitat values.
It’s noted that the upper portion of the stream in the vicinity of the proposed wetlands has mature trees
located along its banks. Removal of these trees will result in some effects to the watercourse. The
applicant is recommended to consider opportunities to keep some of these mature trees along the
stream’s length and include them in the riparian planting plan as they provide a good level of shade and
habitat.
There is a grove of young kahikatea trees on the Temple View side of the proposed borrow pit area. At
the time of the WRC site visit it was thought that these trees would be removed as some re-contouring
would be undertaken in this location. It is recommended that the applicant considering keeping these
kahikatea trees, or if they are to be removed that they are planted elsewhere on the site.

It is understood that some funding has been approved by WRC to contribute towards the stream
enhancement works with the applicant funding the balance of works associated with the design and
implementation.

Policy Statements, Plans and Regulations
6.2.1
National environment standards
As of June 2010 there are five NES’s that have come into effect - the National Environmental Standards
for Air Quality (where various standards have been in effect since October 2004); Sources of Human
Drinking Water; Electricity Transmission Activities; Telecommunication Facilities; and Assessing and
Managing Contaminants in Soil to Protect Human Health. Only one NES is relevant to this application.
National Environmental Standard for Sources of Human Drinking Water
In terms of the stormwater discharge activity associated with this consent process, I have reviewed
WRC’s Smart Maps database and can confirm there are no registered drinking water supplies
immediately downstream of the location of the proposed discharge activity.
6.2.2
Other regulations
There are no other regulations considered relevant to this consent process
6.2.3
National policy statements (including NZ Coastal Policy Statement)
National Policy Statement for Freshwater Management 2014
The Freshwater Management NPS has policies and objectives that direct local government to manage
water in an integrated and sustainable way while providing for economic growth within specified water
quality and quantity limits. The NPS requires regional councils to develop standards to safeguard the life
supporting capacity of water bodies, with the objective that water quality will be maintained or
improved. This will involve protection of high quality water bodies and implementation of methods to
improve degraded water bodies. In the interim, when considering consent applications regional councils
must have regard for any effects (actual or cumulative) that contaminants contained in the discharge
may have on freshwater and fresh water ecology. The principle of adopting best practicable options in
order to minimise effects is included in the decision making process under this policy.
As the discharge consent sought is considered to be a minor activity, it is my opinion that should the
application be granted, it will not be contrary to the Freshwater NPS.
The NZ Coastal Policy Statement is not relevant to this application.
6.2.4
Regional Policy Statement
The RPS is a high-level broad-based document containing objectives and policies the purpose of which is
to provide an overview of the resource management issues of the region and to achieve integrated
management of the natural and physical resources of the Region.
Key issues in the RPS relating to this proposal are the state of resources (Issue 1.1), effects of climate
change (Issue 1.2), managing the built environment (Issue 1.4), and the relationship of tangata whenua
with the environment (Issue 1.5). There are a number of overlapping objectives under each of these
relevant to this proposal. These are listed as follows:
 Integrated management of natural and physical resources (Objective 3.1);
 Decision making (Objective 3.3);
 Health and wellbeing of the Waikato River (Objective 3.4);

I consider that the application is consistent with the objectives and policies of the operative Regional
Policy Statement.
6.2.5
Regional Plan
The Waikato Regional Plan (“WRP”) is operative. The purpose of regional plans is to help the Council
carry out its functions under s30 of the RMA.
Section 3.1.2 – Water Resources Objective
The management of water bodies in a way which ensures:












that people are able to take and use water for their social, economic and cultural wellbeing
net improvement of water quality across the Region
the avoidance of significant adverse effects on aquatic ecosystems
the characteristics of flow regimes are enhanced where practicable and justified by the
ecological benefits, and otherwise maintained
the range of foreseeable uses of ground and surface water are protected
inefficient use of the available ground and surface water resources is minimised
an increase in the extent and quality of the Region’s wetlands
that significant adverse effects on the relationship tangata whenua as Kaitiaki have with
water and their identified taonga such as waahi tapu, and native flora and fauna that have
customary and traditional uses in or on the margins of water bodies, are remedied or
mitigated
the cumulative adverse effects on the relationship tangata whenua as Kaitiaki have with
water and their identified taonga such as waahi tapu, and native flora and fauna that have
customary and traditional uses that are in or on the margins of water bodies are remedied or
mitigated
the management of non-point source discharges of nutrients, faecal coliforms and sediment
to levels that are consistent with identified purpose and values for which the water body is
being managed
the natural character of the coastal environment, wetlands, and lakes and rivers and their
margins, (including caves) is preserved and protected from inappropriate use and
development
ground water quality is maintained or enhanced and ground water takes managed to ensure
sustainable yield
Doc # 9728472
Page 25


shallow ground water takes do not adversely affect values for which any potentially affected
surface water body is managed
concentrations of contaminants leaching from land use activities and non-point source
discharges to shallow ground water and surface waters do not reach levels that present
significant risks to human health or aquatic ecosystems.
Section 3.2.3 Management of Water Resources
Policy 4: Waikato Region Surface Water Class
Section 3.5.3 Discharges
Policy 1: Enabling Discharges to Water that will have only Minor Adverse Effects
Policy 7: Stormwater Discharges
Section 4.2.2 – River and Lake Bed Management:
According to section 4.2.1 of the WRP, the use, erection, reconstruction, placement, alteration,
extension, removal or demolition of structures in, on, under or over the beds of rivers and lakes
may:
 adversely affect bed stability water quality, aquatic habitats, migration of fish, flow
regimes and natural character of river and lake beds
 increase the risk of flooding or obstruct navigation
 adversely affect the relationship tangata whenua as Kaitiaki have with their taonga, such
as waahi tapu, native flora and fauna and access to customary fisheries.
Consequently, objective 4.2.2 of the plan states that these activities must be managed in a
manner that:
 produces a net reduction in the adverse effects of the destabilisation of river and lake beds
 does not have adverse effects on water quality, flow regimes, aquatic ecosystems and
wetlands that are inconsistent with Water Management Objective 3.1.2
 does not obstruct fish passage for trout and indigenous fish to complete their life cycle
 protects natural character of river and lake beds
 there is no increase in the adverse effects of flooding
 avoids obstruction to navigation
 remedies or mitigates adverse effects of existing structures on the relationship tangata
whenua as Kaitiaki have with identified taonga, such as waahi tapu, native flora and fauna
and access to their customary fisheries
 avoids significant adverse effects of new structures on the relationship tangata whenua as
Kaitiaki have with identified taonga, such as waahi tapu, native flora and fauna and access
to customary fisheries
 remedies or mitigates cumulative adverse effects on the relationship tangata whenua as
kaitiaki have with their identified taonga, such as waahi tapu, native flora and fauna and
access to their customary fisheries.
Section 4.2.3 – Policy 2
The plan promotes the sustainable management of structures in relation to rivers and lakes with
the Policy 2 'Management of Structures':
Doc # 9728472
Page 26
Control through resource consents the use, erection, reconstruction, placement, alteration, extension,
removal or demolition of those structures in, on, under or over river and lake beds that:
(a)
cause or accentuate the significant adverse effects of destabilisation of the beds and banks of rivers
and lakes, or
have the potential to cause significant adverse effects on water quality, flow regimes and aquatic
ecosystems in a manner that is inconsistent with the policies in Section 3.2.3 of this Plan, or
occur in natural state areas as identified in the Water Management Class Maps of this Plan, or
obstructs fish passage for trout and indigenous fish, or
may cause significant adverse effects on the natural character of river and lake beds (including
caves), or
increase the adverse effects of flooding on neighbouring properties, or
cause obstruction to navigation, or
cause significant adverse effects on the relationship tangata whenua as Kaitiaki have with river and
lake beds, or
cause cumulative adverse effects.

In my opinion the effects of the outlet structure on the environment are likely to be no more than
minor (see section 6 of this report). On this basis I consider the proposal to be consistent with the
policies within the WRP, providing the outlet structure is installed and maintained in accordance
with the conditions recommended in this report.
Section 5.1.2 – Accelerated Erosion Objective
“A net reduction of accelerated erosion across the Region so that:









soil productivity, versatility and capability is maintained
there are no adverse effects on water quality, aquatic ecosystems and wetlands that are
inconsistent with Water Management Objective 3.1.2
there is no increase in the adverse effects of flooding or land instability hazards
accelerated infilling of lakes, estuaries, rivers, wetlands and cave systems is avoided and the
rate of infilling of artificial watercourses, excluding structures designed to trap sediment, is
minimised
significant adverse effects on the relationship tangata whenua as Kaitiaki have with their
identified ancestral taonga such as ancestral lands, water and waahi tapu are avoided
cumulative adverse effects on the relationship tangata whenua as Kaitiaki have with their
identified taonga such as ancestral lands, water, waahi tapu are remedied or mitigated
significant adverse effects on natural character and ecological values associated with land
and the coastal environment including dune systems is avoided
there are no adverse effects on air quality that are inconsistent with Air Quality Objective
6.1.2, Objectives 2 and 3
damage to property and infrastructure is avoided
in particular in High Risk Erosion Areas….”
Section 5.1.3 Accelerated Erosion
Policy 1: Managing Activities that Cause or Have the Potential to Cause Accelerated Erosion and
Encouraging Appropriate Land Management Practices
Policy 2: Use of Regulatory and Non-Regulatory Approaches of Management for Soil
Disturbance/Vegetation Clearance Activities in High Risk Erosion Areas.
Policy 3: Promote Good Practise.

Regional and Local Air Management
Objective
2:
No significant adverse effects from individual site sources on the characteristics of air quality beyond
property boundary.
The objectives and policies of the relevant sections of the WRP outlined above have been considered
and assessed within the assessment of environmental effects carried out within section 8.1 of this
report. This assessment has determined that based on the implementation of best practice erosion and
sediment controls and dust management, the proposed activities will not result in any adverse
environmental effects which are more than minor. In this respect it is considered that the proposed
activities will not compromise values associated with water resources and air quality or result in
accelerated erosion as outlined within the above objectives and policies and thus the proposed activities
are considered to be consistent with the provisions of the Waikato Regional Plan.
The Proposed Waikato Regional Plan Change 1 – Waikato and Waipa River Catchments (Healthy
Rivers), has been publicly notified and therefore came into effect on 22 October 2016 and must be given
regard to. I consider that the proposed mitigation measures to manage TSS are consistent with the
policies and objectives of the proposed Plan Change.
In assessing this application I have given regard to the above objectives and policies of the WRP. I
consider that this proposal is consistent with the WRP, provided that the recommended consent
conditions and requirements of the relevant rule are complied with.

Other Matters
Waikato-Tainui Environmental Plan
The Waikato-Tainui Environmental Plan provides a background to, and identifies key, resource based
issues for Waikato-Tainui. The plan sets out Waikato-Tainui’s vision statement for environmental and
heritage issues and key strategic objectives such as tribal identity and integrity, including “to grow our
tribal estate and manage our natural resources.” The plan is designed to enhance Waikato-Tainui
participation in resource and environmental management.
I have assessed this proposal against the objectives and outcomes within this plan and overall I consider
that the proposal is consistent with this Iwi Environmental Plan.
Overall, having assessed the environmental impacts of the activity, it is my opinion that the activity does
not compromise the aims and objectives of the Waikato-Tainui Environmental Plan.

2012
6.4.1 Vision and strategy
As of 24 September 2010 Waikato Regional Council, in addition to any requirement specified in the
RMA, must have particular regard to the vision and strategy (Schedule 2 of the Settlement Claims Act).
These Acts apply to applications relating to the Waikato River; or activities in the catchment that affect
the Waikato River.
Doc # 9728472
Page 28
The Vision and Strategy is the embodiment of the settlement act, and seeks to restore and protect the
health and wellbeing of the Waikato River for future generations. The sections of the Vision and
Strategy for which I have had particular regard in terms of this activity are:
a) the restoration and protection of the health and wellbeing of the Waikato River;
e) the integrated, holistic and coordinated approach to management of the natural, physical, cultural and
historic resources of the Waikato River;
g) The recognition and avoidance of adverse cumulative effects, of activities undertaken both within the
Waikato River and within its catchments on the health and wellbeing of the Waikato River;
h) The recognition that the Waikato River is degraded and should not be required to absorb further
degradation as a result of human activities;
i) The protection and enhancement of significant sites, fisheries, flora and fauna;
k) The restoration of water quality within the Waikato River so that it is safe for people to swim in and take
food from over its entire length;
The Vision and Strategy forms part of the Proposed Waikato Regional Policy Statement and is given
effect through the plans administered by Regional and territorial authorities along the river. The
settlement also provides for joint management agreements between Waikato-Tainui and the local
authorities; participation in river-related resource consent decision-making; recognition of a WaikatoTainui environmental plan; provision for regulations relating to fisheries and other matters managed
under conservation legislation and an integrated river management plan.
I have included conditions on the attached schedule which aim to maintain the quality of water and to
avoid remedy or mitigate any potential adverse effects on the Waikato River and its tributaries.
Having given regard to the Waikato-Tainui Raupatu (Waikato River) Settlement Claims Act 2010, it is
considered that the proposal is consistent with the Vision and Strategy document.
6.4.2 Customary activities
There are no customary activities relevant to this consent process.
6.5
Protected Customary Rights and/or Customary Marine Titles (Marine and Coastal Act 2011
(Takutai Moana))
The application does not fall within an area where a customary marine right has come into effect or a
protected customary rights order is sealed.
6.6
Relevant Part 2 Considerations
Part 2 of the Resource Management Act 1991 details the matters that must be considered for the
sustainable management of natural and physical resources including matters of national importance,
other matters, and the Treaty of Waitangi.
The proposed activity has been considered in the context of the matters outlined in Part 2 of the
Resource Management Act 1991 and in my opinion the activity does not compromise any of these issues
and therefore the overall purpose of the Act.

Discussion/Conclusions
Bloxam Burnett & Olliver Ltd has made application for resource consents on behalf of the Church of
Jesus Christ of Latter Day Saints to authorise earthworks and vegetation removal, diversion and
discharge of stormwater, and to construct bridge structures in association with the redevelopment of
the former Church College Campus in Temple View, Hamilton at or about map reference NZTM 1796326
E 5811649 N.
Doc # 9728472
Page 29
The main potential adverse environmental effects associated with the proposed works are considered to
be:







Water quality effects from sediment discharges during earthworks;
Local air quality degradation from dust discharges;
Exotic weed invasion;
Archaeological and cultural effects.
Catchment hydrology and water quality and quantity effects from stormwater discharges post
development;
Hydraulic effects of bridge/boardwalk structures; and
Ecological effects of the bridge/boardwalk structures.
However, for the reasons outlined in section 6.1 of this report, I am satisfied that these adverse effects
can be avoided, remedied or mitigated such that the adverse environmental effects associated with the
works are likely to be minor.
The overall proposal has been assessed in respect to their consistency with the objectives and policies of
the Regional Council’s policies and plans, and the statutory provisions of the RMA. It has further been
considered in accordance with sections 104B and 104C of the RMA which has regard to the
determination of applications for discretionary or non-complying activities and restricted discretionary
activities. Provided the activities are undertaken in accordance with the application for consent and
subsequent supporting documentation, and the recommended consent conditions in the attached
Resource Consent Certificates, I consider that they will not be inconsistent with Council’s policy and
plans, or the statutory provisions of the RMA.
For these reasons I recommend that consents be granted subject to the consent conditions in the
attached Resource Consent Certificates.

Waikato Regional Council’s internal guidelines for consent duration.
Monitoring
The Waikato Regional Council has a statutory obligation under section 35 of the RMA (1991) to monitor
the effects of resource consents being exercised it its region. Waikato Regional Council staff and/or its
authorised agents will therefore monitor the proposed activities throughout the term of consent.
With regard to the soil disturbance activities, it is recommended that the applicant ensures that all
erosion and sediment controls at the site are regularly inspected and in good working order prior to, and
Doc # 9728472
Page 30
immediately after rain events, and that these controls are maintained to achieve optimal sediment
capture efficiency at all times.
It is recommended that the consent holder undertakes regular monitoring and maintenance of the
stormwater system (inclusive of all stormwater management devices, and in particular the wetland
ponds) to ensure optimum stormwater treatment is achieved at all times.
With respect to the wetland ponds and the drain diversion riparian enhancement, it is recommended
that ongoing maintenance of planted areas is undertaken to ensure plants become well established and
replaced when needed.
All costs associated with monitoring are recovered from the consent holder on a reasonable and actual
basis.

for in Condition 15 hereof, where they have been caused by the stormwater diversion and
discharge activities authorised by this consent.
Advice Note: Stormwater diversion and discharge activities in conjunction with urban land-use,
can adversely affect flood potential by either limiting the rate at which stormwater drains from
a catchment, or by increasing the rate and volume of discharge to downstream catchments.
Whilst such effects are the subject of this consent, it is also recognised that ‘levels of service’ for
flood alleviation in urban catchments are established by territorial authorities through separate
statutory procedures and community consultation. The ‘levels of service’ that are established
between the territorial authority and the community are not the subject of this resource
consent.
15. As soon as practicable after becoming aware of any of the adverse effects of the nature
specified in Condition 14 that are more than minor, the consent holder shall submit a report
to the Waikato Regional Council in relation to the adverse effects. As a minimum, the report
shall include:
a.
b.
Doc # 9728472
A description of the adverse effects;
A description of the cause of the adverse effects;
Page 45
c.
d.
An explanation of any measures taken to remedy or mitigate the adverse effects,
the outcome of those measures, and whether further measures are necessary and
reasonably practicable;
If no measures have been taken in accordance with (c), a description of any
reasonably practicable measures that could be taken to remedy or mitigate the
adverse effects and a recommendation as to whether those measures are
necessary.
The consent holder shall liaise with the Waikato Regional Council with a view to determining
any reasonably practicable measures which should be taken to remedy or mitigate the adverse
effects.
Advice Note: Separate resource consents may be required to undertake remedial or mitigation
works. The consent holder is advised to obtain all such consents at its sole expense, prior to any
works being undertaken.
Stormwater Quality and Receiving Environment
16. The consent holder shall manage the stormwater network to avoid as far as practicable and
otherwise minimise, the discharge of any substance that is likely to cause the production of
conspicuous oil, or grease films, scums or foams, or floatable suspended materials in
stormwater receiving water bodies after reasonable mixing.
17. The consent holder shall manage the stormwater network to avoid as far as practicable and
otherwise minimise, the discharge of suspended solids and any other substances that are
likely to cause the following effects in stormwater receiving water bodies after reasonable
mixing:
a.
b.
c.
Conspicuous changes in colour or visual clarity;
Increases in suspended solids concentrations by more than 10 percent;
100 grams per cubic metre suspended solids concentrations or greater.
Advice Note: For the purposes of this condition, the suspended solids discharge parameters
referenced above shall only apply to the post development stormwater discharges authorised
by this resource consent and do not apply to the earthworks activities which are authorised
under a separate land disturbance resource consent.
18. The consent holder shall manage the stormwater network to avoid as far as practicable and
otherwise minimise, the discharge of hazardous substances in concentrations that are likely
to adversely affect aquatic life, or the suitability of water for human consumption after
treatment. Where a question arises as to whether the concentration of any particular

application of the Microbiological Water Quality Guidelines for Marine and Freshwater
Recreational Areas (MfE, 2003), or any other technical publication approved in advance by
the Waikato Regional Council in a technical certification capacity.
20. The consent holder shall manage the stormwater network to avoid as far as practicable and
Doc # 9728472
Page 46
otherwise minimise, discharges that are likely to adversely affect aquatic ecosystems and
cause the following effects in the downstream watercourses of the Koromatua Stream
Catchment after reasonable mixing:
a. Dissolved oxygen levels to fall below 80% of saturation;
b. pH to fall below 6 or exceed 9;
c. Suspended sediments to smother benthic organisms;
d. Undesirable biological growths;
