6. I I The rcle\'ant City Vicw Ohjl;.'Ctivcs arc complied wilh :IS follows:• Objl;.'Ctive I TIle filling of the gully will enable the eompllct, orderly and connecled residential
dcveloplJlcntto occur in lhe suburb. Presently Ihe lund is lying in waste and unable to be usedfor the intended purpose ohesidential development.
• Objective 2 The future residential developmcnt to occur uft.,:r the filling of the gully willenable the provision of security of supply for services to the Abhy Road and Woodgate Counrl;.'Sidences which arc currently servie.,:d by dend end mains.
• Objective 3 The filling of the gully will enable wnnectivilY to the existing roading pattern aspun of the future residential dcvc1npmellt. Prc.<;clltly Abby Rond is a dead end road tenninatingwithout any manoeuvring area. This situation has already resulted in Council incurringadditional costs in lhe reconstruction of II vehicle crossing damagl;."(! by heavy vehicles using 11when turning around. By not filling of the gully this will prevent the cumplction of the roadingpattern for the development which has been intended for the past 20 years and prevent anychance of connectivity.
• Objcctive 5 The filling of the gully will enable the continuation of the high quality residentialdevelopment on land loned for that purpose and reduce the need lilr expansion into productivefarmland on the outskins of the City. It will also eliminate an unsightly situ:ltion of abandonedland that is not bcing utilised for any purpose.
• Objective 9 The filling ofthc gully will ensure that a coordinated approach occurs for thefuture n..'Sidcntial development of the area. No such approach can occur ifthc gully is not filkd.
• Objecti\,c 1\ The filling of the gully will cnsure that good urban dl;.'Sign lor all integratedde .... elopment for the future rcsidenlial in the arC:l con occur. No such design can occur if thegully is not filled.
• Objective 19 The filling of thc gully will eliminate all existing nalural hazards without creatingan)' new ones.
6.12 All assessment on rclevantmattcrs to Pan 2 of the Resource Management Act is provided as follows:• The proposed subdi .... ision and filling ofthc gully arc in lIecordance with s5 ofthc Act by
enabling the developmenl of tile land in geneml accordance with the objectiVes and policies ofthe District Plnn while cre:lting ad ....erse effects thut ure no more than minor or of a Icmpomrynature only.
• There is full compliance with the rele....ant mailers identili...-d in s7 oflhe Act as:(a) KaitiaicitlUlga. The lilling of the gully will not have any impact upon the adjoining lnnd
in panieular the Reserve and well ensure that the current situation of Wel;.'<is andundesirable plants left 10 grow on the land will bc removed.
(all) The ethic of stewardship. The land in its current state is unusable and not providing abenefit to anyone. Once the gully is filled It provides an opportunity for efficient usc ofthe land for residential development.
(b) The eOicit..-nt usc and managellll:nl natural and physical resources. Filling ofthe gullywill enable the usc of land which otherwise will be unusable.
(ba) TIle efticiency of the end usc of energy. Not applicable.(c) The maintenance and enhancement of amenity values. As lhe gully does not presently
have an amenity \'alue with the \\Iork lhnt has already been prcfonncd and the gorse etcthat is growing on it. the filling of it will remove the unsightly viC\\Illnd cflllbic highquality houses to be l.'Slablishl.:<1 ill the future. The filling will not affect any view thatany adjoining property may have of the adjoining reserve.
(d) Intrinsic values of ecosystems. TIle existing gully docs not have any intrinsic values.(f) Maintcnance and cnhancemcnt of the quality of the environmcnt. The existing gully is
detrimental to the existing environment due to the growlh of weeds, gorse etc. Filling ofthe gully will eliminate all of lhese issucs while nOI alTecting the adjoining reserve.
131
(g) Any finite churacteristics of ontuml aod physical resources. Filling or the gully willensure utilisation of presently unusable land, thereby reducing the need for urbanexpansion onto produetivc rural hmd.
(h) 11te protection ortlle hahitut oftmut and salmon. Not applicable.(i) The eR"ccts of climate change. Not ;lpplieah1c.0) The benetits to be derivcd from the usc and development ohenewable encrgy. Not
applicuble.
None orlhe aOO\'e mailers have a specific relevance to the eXlCnsion of Abby Road or the creation ofLot 523. both of which arc in accordance with lhc Objectives and Policics of thc District Pilln.
Overall the proposal achie\'t.'S the sustainable management purposes of the Resource Management Act1991.
6.13 In granting a landusc consent for the filling of tile gully. Horizons Regional Council has: dt.·(:rncd thatthere are not any affected panies and th,1t consent is not required from any neighbour. This funherreinforces the conlention that there arc not any afft."Ctt.-d par1it.'S and thaI any fonn of notification is notrequired
6.14 It is considered tbat the proposed subdivision and filling of thc gully does not crcale uny effeels beyondthe property boundaries. Any effects from the construction of the mading Bnd filling or the gully nrc ofalemporary nature only, arc no marc than minor and no greater that those allowetl for penlliucdactivities. Therefore it is considered thaI as tht.'TC arc not any nffectt.'d ponies for which COOSt.'t11 could berequired from. that neighbours consent is oot required. nor is any fonn of notification required.

This report;
Identifies the extent of investigative reqlJirements under Palmerston North City Council (PNCC)
policy documentation;
Provides an assessment of the currentiy available and precedent information;
Summarises the results and conclusions of the site investigations completed to date; and
addition~1 testing currently being lJnderta~en,
Provides proposed earthworks construction methodologies in relation to the guily fill1ng works.
1.2 Background
A resource con~entl for filling the "Abby R.o~d Gully" site was i~sued by the PNCC on 11 May 2007. The
resource consent ref~r~nc~s th~ original sit~ investigation and design report by D~vid Napier ~nd
A~sociates',
Astart was made on the consented wor~s in 2007(2008, by stripping out the head of the gully,
underta~ing an engineering inspection of th~ sit~ preparationl, a design and sp~cilication for the
proposed filling works', and the installation of SUb50il drains and stormwater and sediment control
wor~s. The works then IJpsed outside the consented period for completion, until iate 2015, when the
site was rest ripped and a smail amount of fill was placed from earthworks involved in the extension of
Johnstone Drive.
The gully filling earthworks are shown in the Pirie Consultants' Plans attached to this report as Appendix,.

1.3 Previous Geotechnical Report
The geological conlext of sile is well described In the David Napier and Asscciatei lid Report r41 Speciflt
Ilemi of note are the conte~1 with reipect 10 seismic risk, geomorphology, and site ~pecific
characterislics.
The report nOles Ihree faults In relatively close pro~jmity 10 lhe ~;te; a south·WeillO north·eaSllnaetlve
fault located along the base 01 the Tararua Ranges some 3km NE of the site, a north·west to $Outh-.east
Inactive fault running perpendicular 10 the Tararua Ranges and located some <I km soul II-west of the
site, and lhe most signiflCanl - the Wellington faull running south·wesllo north·east along the eastern
side of the Ta/aNa Ranges and localed some 8 km Irom the slle. \1 Is Iherefore concluded Iha! all
earthworks must be designed and evaluated for a moderate degree of seismic loading.

The slle geomorphology Is taken from sheel 11 Dannevirke 01 the DSIR geologkal map lor New Zealand
110250,000 scale. This describes the terraces as OSb: sand and gravel, with some lacustrine silt and clay
deposits; commonly overlain by three loess/paleosol couplets and a tephra. SOils Information Is taken

Tokom~rusilt loam on the adjacent terraces. Both soils ~re described as loess with poor intern~1
drainage characteristics.
A walkover survey of the he~d of the gully iderttilied the proposed Ii II ~ re~ ~s beirtg ~pproxim~tely 260
m lortg and 60 m wide. The gully floor was wet ~Iong most of the length with an undulating b~se
providing a series of small dams. A check of the gully sides did not reveal any obvious springs or seepage
elevated ~bove the gully floor further there were no marsh grasses located in the gully floor Indic~ting
moisture was not a prominent feature.
Samples were take~ from exposed soil a~d submitted for laboratory testing to determi~e the
earthworks piJrameters: existing and optimum moisture content and maximum dry density, The tests
determined that existing moisture wntent was approximately 17%, optimum moisture content for
maximum wmpoctor density was approximately 24% i.~. significantly wetter of natur~l, and the
maximum achievabie dry density under standard compaction was in the range 1.5 to 1.S t/m3.
Based on the existing soils and me~sured strength parameters the emb~nkmentat the head of the gully
fi[1 area w~s designed with a gradient of one in three, assumed sail weights of lSkN/m3 for the
foundation Jnd 18.5kN/m3 for the wmpacted fill material and assumed cohesion of zero and thi value
012S".
A safe setback distance for proposed buildings from the edge of the embankment slope at the end of
the fill section of the gully was assessed at 7m for an assumed maximum fill depth of 8m at the
embankment end. Subsoil drainage in the base of the gully was proposed via a 400 x 400 mm trench
containing a minimum 110 mm diameter he~vy duty flexible subsoil pipe laid in filter m~terial, (pe~
metJI and filter cloth).
Emba~kment construction fill was proposed at 300 mm ma~imum friliayer with moisture content within
the range +2-4% of optimum a~d achieving at least 9S% of maximum dry density as per NZS4431:19B9
Code 01 Practice for Earth FiiI for Residential Development. Fill not to be placed on any surface steeper
than one in 10, (i.e. the gully sidesL which are to be benched.
The report also proposed that the fill area be post consoildated with a 2 m depth of surplus material
placed over the site for 12 months to provide an effective 33 kPa loading, and any settlement of the site
TO be accurately monitored with survey levelling.

B~sed on Table 1 and Figure 4 above the worst c~se scenario for the proposed earthworks land
designation is uodevelopable for the Abby Road Gully. Therefore, the "undevelopable" land requires a
geotechnical report covering slope stability assessment for the front face.
1.5 Additional Soils Information
The existing information avall<lble for the site includes the following sources: The Slope Stability
As,essment undertaken for Stage fie Landcnre New Zeaiand Land Resource loveotory {NZLRI) maps, a
study conducted by Cowie in 1964' which ideotifies typical soil profil~ io the area, and a geote~hni~al
assessmeot report of aoother subdivision ill the area by Opus. In this sectioll illform~tioll from these
sour~es is summarised and discu,sed in respect to this report and proposed earthworks.
NZLRI m<lps provide inform<ltion on: slLp ilnd erosion potenli<l I, rock type, soli type and slope. Thes~
milps show that the Abby Road Gully steepen, to a negative gradient (down to 2S degrees but averages
around lS degrees) on the gully sides. The slip and erosion potential is negligible on the flat areas but
slight in the surrounding gullies. The rock type has been classified as loose sedimentary rocks with
overlying silts. clays and sands.
The soil profile i, re,ogllised <IS Perch-gley PilUie which occur in sites that are periodically saturated in
winter <lnd spring <lod dry out in the summer. The presence of perched water tables on impermeabie
subsurface layers is not uncommon'.
The stlJdy by Cowie" was on a site close to that of the proposed earthworks (within ca. 2,Skm). It
suggests that the soil profile ,an be 'hara'terised <IS: it I~yer of Aokilutere loess greater than 2m thick,
overlying a 3m thick I<lyer of plilstic c!ily with concretions, followed by a layer of dune sand. The source
dat;:, in comparison with the site loc;:,tion is shown in Figure S below.

The Opus report' noted sever<lll<lndslide scraps <lre evident on the site slopes but the identified
landslides are shallow and not expected to create ha~ards for the earthworks. Opus analysed the
stability of the site slopes and concluded that the site had adequate stability for the proposeddevelopment,
The e~isting information summarised above is gener<llly consistent and nllows some conclusions to be
drawn when interpretntion the site investigation and survey data:
The soil strata are likely to consist of silts, clays and sands with sands being found lower in the
strata than silts and clJYs. SoH is of Palik stratification and often satu rated in winter and spring
months but dry in the summer, presence of perched water tables could be common.
Bed rock may be located quite deep into the strata and river gravels are to be expected, below
the lo~s:; I ash layers.
An intermittent layer of Aokautere Ash could be prese"t in some locations.
There Is a slight slip and erosion potential recognised for the site,
Effective shear resistances of the loess: and sand I gravel layers could Ii~ somewhere between 29
- 36 and 3S - 42 degrees respectively.

2 Site Investigations and Design
2.1 Scala Penetrometer Testing
Site investigations conducted or supervised to date by NZET ltd have comprised aseries of SCalapenetrometer tests along the Abby Road Gully main axis. and gathering of soil samples for
characterisation of geotechnical parameters. This was to assess both the foundation strength and likelycompressibility and the deg'ee of compaction of the (minor depths) of rill plilced to dille.
The location of the soil testing and SCala penetrometer test results are shown In ligures 6 and 7below.

4 Slope Stability Assessment
Aslope stability assessment is required as part of this geotechnical report under tile Tokin and Taylor'
policy document produced for the PNCC (refer to section 1.4l. The aspects of the slope stability
assessment to be induded in this section are as follows:
A review of the precedent inform;3tion in rel;3tion to m;3jor slope ;3nd ground f;3ilure,
The det;3ils ;3nd results of slope st;3bility modelling using the computer software package Oasys
Siope,
A sensitivity based risk analysis required due to the variance in soii parameters and potential risk
to loss of life and damage to property, ~nd
Definition of a safe slip bound~ry as a result of the above which defines the safe setback
distances from the edge of the front face I embankment slope of the Abby Road Gully
4.1 Precedent Information
The e~isting site information discussed in section 1 suggests that the proposed e;3rthworks ~rea possess
,orne ,lip and ero,ion potential; however, this section is concerned primarily with the potential for
major slope slip and ground failure causing damage to property ~nd loss of life. The sources of
precedent information analysed mainly consist of historic aerial im;3ges, for changes in landform" and
enquiries with the PNCC and local knowledge (e,g. former owner, and Contractor).
Analysis of existing aeriai imagery suggests th;3t the Abby Road Guliy, has remained a relatively stable
and unchanged landform between 1968 and 2013. The observations from the aeriol imogery are
confirmed by the walkover survey.
Although the slope stability assessment completed for Stage 6C found several shallow ,eated localised
slumps in the PNCC r<~serve gully to the west. This is expected as the erosion and slip potential for the
PNCC reserve western gully W;3S significantly higher given the slightly weaker soil strength parameters
and the formation of a lake [n the bottom of the BU[ly.
Enquiries with PNCC staff, Tony McGlynn (Subdivision Engineer) and Steve McNichol1 (Compliance), onthe 26'" of August 2013 identified that PNCC were not aware of any major slope and ground failure
issues In the wider Aokautere area.

4,2 Slope Stability Modelling
Based on the topography shown in the 2007 design documents, (Abby Road Plans - David Napier
Report), preliminary slope stability analyses were undertaken u,ing the Oasys 2 dimensional analysis
programme which analyses for a slip circle or slope failure. The analysis was on the embankment slope
grade of 1 vertical to 3 horizontal and 11m total vertical height. Three soil strength options were
considered; 80, 100 and 120kPa. Note that the proposed fill materi;,ls compacted as proposed should
achieve;, reliabl~ str~ngth in excess of 120kPa. The analysis used a conselVative horizontal load seismic
coefficient of 0.3g, with no vertic;,1 component.
Results are tabulated as table 3 and the graphical analyses shown as figure 13 below,

Table 3. Slape sIaM/tv analysis far three soil strength options - embankmenl slope 1:3.
For buildings;, desirable FOS is in excess of 1.3, wherea, for roads typically 1.1 is considered aCCi!ptable.
At the current slope of 1:3, the critical section is also not at the embankment i!dge but around 15m
back, although construction right to thE! i!dgE! would not be desirable for other reasons.
NZET's experience with the site soils in the general area is that they are typicaily as represE!nted by the
historical analytical results (AppE!ndi)( C), from samples taken from the other side of the Johnstone Drive
Gully, and fill st;,bility at the proposed or modified depths and embankment slope grades with similar
soils should be readily achieved.

5 Conclusions and Recommendations
5.1 Abby Road Gully Filling
With the proposed filling method of vertical compaction in horizontal layers, the most likely form of
mass instability / failure would be a cla,5ical slip circle.
Following the receipt of the ,oil test results for the ~ctu~1 sDil to be lJsed to fill the guliy, (yet to be
selected). a further slope analysis and recommended set back distances from the top of the proposed
embankment slope will be modified / confirmed. Subject to confirmation from that testiog the
coostruction recommendations given in the Napier Report ~re considered to likely be ~ppropriate_
constructioo control ~nd verific~tioo is recommended via;
Wetting ~s required, completion of comp~ction ~nd testln~ of the relatively smallthickoess of
mat~rial alr~ady laid, (effectively one iayer)
Ongoing soil compaction at the recommended water content range and I~yer thickness likely -4
+2% of optimum mc ~nd 200-300mm thick layers, s~mple, to be independently tested at thO!
rate of 1 sample per working daySc~l~ penetrometer / CIO!gg Hammer testing of prepared subgr~de on 10m grid per layer to be
undertaken at the end of each day's filling, testing by contractor's t:onsultant
Soil density testing by Nucle<lr Oensometer at the rote of 4 tests per 600mm, testing by
independent l<lborotory, required level >95% NZ standard_
Recording and submission of all results.
Soils outside specification to be reworked and retested
Monitoring of the filled gully for settlemeot for 24 months minimum from the completion of the
earthworks,
Fill to be certified with a report and 2A Certificate.
The site soils are sensitive to high water conteF'lt and erosion. it is recommended that future
development comply geoerally \\lith the following documents:
PNCC Paimerston North Residentiai Design Principles and Guidelines - Geotechnical
Con,ider<ltion5 for the Aokoutere Area, May 1996,
NZS 4404:2010 Lond development and subdivision infrastructure

All stormwater generated from buildings and signifi~ant Iwrdstand areas Of) the developed fill

gully, well away from the gully slope.
All new cut and fill slopes and bare ground should be re-vegetated as soon as practicable and
such vegetation should be maintained.
Property owners of sections bordering on the embankment slope should be provided with il
brochure summarising restrictions on activities whi~h may 5timulate erosion near the edge.

Abby Road Subdivision of lot 523 - Site Contamination Status
The National environmental standards for contaminated sites 20III, require that sites whicharc known to have been occupied by activities on the HAIL list, or other sites on whichsimilar activities arc known to have occurred should be investigated to an appropriutestandard commensurate with thc activity",
The fuct thut an activity or industry appears on the list docs not l11e31l th3t hazardoi.lssubstances were used or stored on all sites occupied by that activity or indust!)'. nor that a siteof this sort will have hazardous substances present in the bnd. The list merely indicates thatsuch activities and induSlries are more likely to use or ston: hazardous Sllbstances andtherefore there is a greater probability of sile contamination occurring than othcr uscs ornetivities. Conversely, an activity or industry that docs not appear on tbe list does notgllaruntee such a site will not be contaminated. Each case must be considered on its merits.considering the infonll<ltion at hand.
In applying the list, it must be remembered that particul<lr activities are u small part of apanicular indust!)', with the activity generally localised within larger sitcs. For c;-;ampkanimal dip sites arc listed, but fanning is not. This is becausc dip sites are only a small part ofn farm and fanning, and in geneml, do not have a high potcntial to sprcad contamination overthe completc farm. Therefore, the possibility of contamination will oilly be for a part of theland.
Thc regulations require <Jctcrminations and investigations 10 be undertaken by anappropriately experienced and qualified contaminated site practitioner. Stu Clark CP Eng husbeen investigating and reporting on contaminntc-d sites sinc~' tile mid 1980's, has reported andreviewed numerous siles and is considered an appropriate person.
A 2013 NZET report undertaken on thc nearby Lot 691 DP4075S0, Stage 6C - Aokautereincludcd site tcsting as there was a holding paddock where dipping I animal reme<Jy treatmentcould have occurred. In that report samples were taken and came back with 110 contaminantstlmnd.
A later NZET repon on stage (j.1 C of the subdivision land involved sampling as the farmhOllse and sheds were thought to have been used for storing fann chemical supplies. Someminor contamination was found but mostlikcly related to historical paint removal from thehouse.

NZET have now been asked to eOlTIment on the likely eon1l!minatcd ~itc status I need forinvestigation of the land associated within the proposed Abhy Road Gully filling and creationof lot 523 at the end of Abby Road.
Anecdotal evidence is that this land has always been in gnlzcd pasture. Recent and olderaerial photographs support this. Accordingly. in my professional opinion, there is no reasonto infer any likelihood of crllltamination and not nccd to invcstigate this site further.

1. Introduction
My name is Angela McArthur. I am a landscape architect and a registered member of the NewZealand Institute of landscape Architects.I have been requested by Pirie Consullants Ltd Palmerslon North on behalf Aokautere Land HoldingsLtd, 10 undertake an assessment of visual effects lor the proposed earthworks application to fill theAbbey Road Gully as part of the Stage 6F2 Woodgate Subdivision, Aokaulere.
In order to do this assessmer11 report I visited the site and general Aokaulere Development area on21 March, 2016.
This report sets out to describe, evaluate and assess the landscape and visual effects of the propos,,1against requirements of the Palmerston North City District Plan and relevant RMA malters
2. Background and Proposal
The proposal is to carry out the bulk earthworks first consented to in 2007 alld approved underPalmerston North City Council Resource Consenl Decision RM 2466. This consent has 1101'1 iapsed.The currenl proposal is to carry out earthworks in general accordallce with that lapsed consent asshown in the aUached plans and reports.
Detalis of the curren! proposal are shown on plans 2043/137 prepared by Pirie Consultants LId. datedMay 2016. The proposal is 10 carry out earthworks to fill the upper section of Abby Road Gully beyondthe PalmerSlon North City Council owned reserve; alld to creale one additional lot within theResidential Area. II is anlicipated that this proposal to fill the gully will be completed within a 5 yeartime frame.
The proposed maximum depth of fill is 11m above tile boltom of the original gully. The tolallenglh ofgully to receive fill material is 260m. The maximum widlh of fill Is 75m.
The site is located within residential land in the Aokautere Development Area, The gully is shown onPN City District Plan, Map 10,1 as 'Undevelopable Land'. This designation is assigned because ofpolential difficulties to develop the land sa!ely due to slope instability and earthwork requirements.
No reference is made to the protection of landscape or visual amenity values associated with thegully. The site is within the residential zOlle and shown on PNCC general Planning Map 23.
This purpose of this report is to assess the landscape and visual effects of the consent application.
3. Site Character
The proposal site is within the upper reaches of a local guliy. The gully below the site Is a now areserve owned by PNCC since 1994. The reserve within the lower gully has improved ecologicalvalues due to the planting of local indigenous species and creation of a weiland area.
Viewpoint 3 shows the general area where the existing gully meets the reserve.
Above the site the gully has been filled in the paslto develop house lots wflhin Abby Road, WoodgateCourt and Johnstone Drive as part of the Pacific Drive residential area, Viewpoint 1 sho\'ls theproperly at 5 Woodgate COLJrlthat abuts the gully.

The proposal site (within the gully) shows signs of variable land modification and some fill is alreadyplaced in the gully. Earlhworks have previously occurred as part of the expired resource conseflt.Significant amounts of fill have been placed \0 create existing lots surrounding the upper gUlly area.(see Viewpoints 1-3 ). Subsoil drainage work has already been completed to comply with
geotechnical requirements for the earthworks.
No significant vegelation is found within the site. Land cover comprises weed species such as gorseand rank gr.:lSS (Viewpoints 1, 3), The extension of Abby Road is proposed to cormsct 10 JOhnstoneDrive, Earthworks for the extension of Johnstone Drive have begun but are currently notoccurring. However this work is nol part of this appiication,
The visual character found is both, established and emerging residential developmenl within PacificDrive residential area, Areas of established housing within lhe Pacific Drive area are residEmlial in
scale and form.
Due 10 the flat topography residentlai araas closa to lhe site have limited views of undeveloped areas.Outlooks ala ganaraily restricted to the streetscape wilhin property frontages and to boundary fencesand vegetation within local properties.A few properties edging lafld located at top of the existing gullyhave restricled views over the proposal site afld beyond.
The flatural character of the area is open and nat. The dominant landform is flat river terrace and landuse in the pasl has been pastoral. The network of local gullies found within flat terraces is a m.turalfeature of the area. The general area has been described as an 'elevated flat' within Landscape Unit14 in lhe Palmerston North Landscape Inventory'. The landscape unit includes the general area of thePacific Drive community. The gully is a landscape feature not unique within the area and has adegree of similarity to many parts of the unit. The landscape unit is also described as haviflg variable
to low sensitivity to change.
The dominant land use found now within lhe Aokautere Development Area is residential withassociated land designated by council for recreational use, roads and reserve areas.
4. Assessment of Landscape & Visual effects
Methodology
Landscape assessment within the context of this report is used in a broad sense to encompass thegeneral meaning of assessment and ways of looking ai, descrlbir1g, and evalualing the landscape, Adistinction is made between lar1dscape effects, which derive from char1ges to the physical landscapeand how it is experienced ( perceived values), and visual effects that relate to changes that arise fromthe composition of available views. people's response to changes to the landscape. and the overalleffects with respect to visual amenity.Tile assessment of landscape effects in this context is primarily concerned with visual effects onneighbours as lhe landscape characler is defined by the recent subdivision in the area and will remainunchanged. The effects of this proposal; filling the upper section of the remaining gully are iimitad tothe visual effecls, the receptor(s} and the magnilude of these effects.
The methodology used to assess visual effects involved looking at the physical catchment andcharacler lhal would be exposed to visual change. The following scale has been adopted tocategorise the polential impact of visual change from representative viewpoints.

A number of viewpoinls are chosen from localions surrounding the proposal site thai are significant inlerms oflhose seen as potentially mosl affected.
While il is recognised that filling lhe gully to provide opportunity for new housing and roads couldpotenlially increase Ihe magnitude of visual impacts, lhe scale and lype of effects would essentially bethe same as that which already exists in the wider neighbourhood, Consequently there is negligiblechange to lhe visual amenity or "haracter in relalion to lhe wider environment, Further the site iszoned for residenlial development and anticipated for this activity.
The land is zoned for residenlial development and Ihe dominant land use in the area is residen1ial.While Ihe gUlly network has been recognised within lhe Aokaulere flal terraces as a natural featurethere is no special reference to protecting this section of the gully, Provision has been made to controlstorm water as a resull of filling lhe gully. The inclusion of a [ower gully as council reserve will offsetthe loss a remaining natural, but significantly mOdified feature.
Overall landscape effects are considered iow to moderate. While the proposal to fill the upper gullywill change lhe physical landform, the significance of these changes are low due 10 Ihe level ofmodification already carried out within the site; lhe pasl filling of upper seclions of the gully and thelack of ecological values remaining.
The visibility and nature of visual effects may detract from, conlribute to or nol subslantially changethe character overoll of lhe existing environment. The visual effects of any development will alsodepend on the viewpoint; the locations of the viewing audience and whether the view is transilory orstalic,
The lower baller of the proposed fill has been designed to integrate easily to resemble a naturallandform, Any significanllandscape effeels remaining after fa planling the lower baller will be low andeffects nol uncharacteristic of similarly designed earthworks for new housing found in the surroundingarea.

fb) Avoid earthworks that materially impart an ti,e landscape and visual values asoocjated wil!! the

Landscape and Visual Impact effects
The landscape effects of filling the gully are reslricted directly to the gully and effects on Ihe reservebelow. The proteclion of the gully \lIithin the council reserve area will help to offset any losses oftandscape value withinlhis section of the gutly. However the site has limited lal1dscape valueremaining dlle to past modifications to the landform and vegetation. Fill malerial has already beenplaced. Generally the site is degraded; the dominant land cover is weed species such as gorse andrank grass.
Subsoil drainage work is already completed in accordance with geotechnical requirements. Anyadverse landscape effects remaining after restoring the tower batter with planting witl be low and notuncharacteristic 01 earthworks already completed for new housing in the surrounding residential area.
The visual impact of filling the gully and future residenli(ll development will be low due to thesurrounding f1altopography and existing low qU(llity of the site, Views from the existing residentialarea are domin<lted by more distant view 10 the hills. The visual impact of filling the gully will benegligible to low.

Effects on adjoining properties including amenity values
Landscape Effects on adjoining properties are limited to:
• A change in land cover due to removal of weedy vegetation now preSBrlt within the edges of thegully.
• A change in ground level due to filling the gully to match the flat ground found within Ihe wider area.
Once the gully is filled the anticipated visual impact would be pretty much the same as belore,however there is potential for improvements once weed species are removed and the area restoredwith grass and new planting within the lower baUer. Once developed for residential hOUsing lhe viewwill change.
Visual Effects on adjoining properties are limited to:
• A small number of properties located around Ihe edge of the upper guliy {within Abby Road,Woodgate Court and Johnstone Drive} that have no or restricted views over the gully.
These properties which have been identi~ed earlier in this report as potentially affected howeverhaving Iimiled views in lhe direction of the gully due to Iiat sile topography, the single level form ofhousing and 1,Om high boundary fences that abut the edge 01 the gully.The dominant ouUook from these properties is currently distant hills that make up the foothills ollhe
Tararua range.
The guliy has not been identified as 'an outstanding natural feature or contributing to an outstandinglandscape' in the PNCC district plan or any other relevant document In iI's present stage the site isloVi iandscape and visual amenity value.
This scaie of earthworks is anticipated to facilitate the construction of the future road and reSidentialsubdivision anticipated in the Aokautere Development Area_
6. Summary & Conclusion
in summary, established housing within the Pacific Drive mea is residential in scele and form. Due tothe flat topography residential areas close to the site have limited views of undeveloped areas,Outlooks are generally restricted to Ihe street and property lrontages, boundary fences and vegetation
within local properties.
Any adverse landscape and visual effects of filling the upper section remaining of the Abby Road gullywill be oflset by the:
• Design of the batter \0 resemble a natural landform.• Planting of the batter proposed that will help integrate the site with the reserve below.
• Opportunity to improve ground slabilily below existing properties adjacent to the top of thegully_
• Provision made for access 10 the reserve from future resider'ltial development.• Future extension of Abby Road and connection to Johnstone Drive.• Limited number of receptors to views into and across the gully.
• Restricted nature of the view from properties identi~ed as potentially affected.
• The stormwater drainage occurring from adjoining properties is unaffected by the filling.

Overall the visual impact of filling the gully will be 101'1 due to the affects being less than minor on alimited number of people and the significance of this view lor lhose affected. Properties potentiallyaffected have limited views in the direction of Ihe gully due to flallopography surrounding the gullyand lhe single level form of existing housing. Boundary fencing currently abutting the gully edge alsoblacks out potential views for existing properties surrounding the top 01 the gully.
A timeframe of 5 years is proposed to complele earthworks to fililhe gully and restore new groundlevels for future residential subdivision anticipated on the land,
In conclusion the effects arising from the proposal are similar to those ,mticipated in the OperativeDistrict Plan. It is therefore concluded that this earthworks proposal carl be absorbing irlto the widerurban area and that the loss of visual amerlity for existing residents will be less th;;ln minor.

1. Application
1 '! BackgroundThe appli~ant, Aokautere Land Holdings Ltd, has applied to undertake earthworks for a subdivision
located off Johnstone Drive, Aokautere, Palmerston North, This application also requires a subdivision
and land use consent from Palmerston North City Council.
In addition to this resource consent which is required under the One Plan 2014, additional consents are
required from the Palmerston North City Council. The applicant will not be able to commence physical
works as authorised by this consent, until the relevant consents have been granted by the City Council.
A site visit with Pita Kinaston, Compiiance Monitoring Team Leader, Stuart Standen, Compliance
Monitoring Officer, and Fiona Morton, Consultant Planner was undertaken in late Mar~h 2016.
1 2 Application Dr:scriptjOtl
On 1 March 2016, Pirie Consultants Ltd, on behalf of the applicant, Aokautere Land Holdings Ltd applied
for a land Use Consent, to undertake earthworks (land disturbance) exceeding 2,50011')' on the Johnstone
Drive subdivision site to complete a cut and fill sequence. The 'wt' component of the works will result in
the continuing formation of the Johnstone Drive road, with the 'fill' component O~Cllrring in the neorby
Abby Road gully.
Section 6.1 of the application clearly states that it is not intended that there will be any fill material
imported to the site. However an email received on 14 May 2016 identified that other sour~es of fill may
be obtained the adjoining properties of lot 1 DP 464570, Lot 98 DP 330144, Lot 1003 DP 4900n and Lot
1021 DP 494066.
No term was sought in the application, but on 14 April 2015, the applicant modified the application and
sought a ten year term.

2. Assessment
~.I SectioIl104(1}(a} Environmeof<7/ EffectsSection 104(1)(a) of the R.esource Management Act states that when considering an application for a
resource consent the consent authority shall have regard to any actual and potential effects on the
environment of allowing the activity. The following actual and potential adverse effects have been
considered:
Location, nature, scale and timing of the activity;
erosion and sediment effects,
soil conservation and stability; and
potential adverse effects on watercourses.
While the application states all runoff will comply with the visual clarity standards of Schedule E of the
One Plan, it does not elaborate on how this is to be achieved. The application states that any adverse
effects will be temporary and limited to within the property boundaries.
When the application was first lodged in March 2016, no E&SCP draft or otherwise was induded. A
section 92 request was made on 15 March 2015, which in particular, requested that an Erosion and
Sediment Control Plan was prepared to Greater Wellington guideline standard and provided to the
Regional Council. A draft E&SCP was received on 7 April 2015. This was reviewed by Stuart Standen,
who considered that plan did not meet tfle Greater Wellington guidelines. Consequently a revised E&SCP
was received on 10 May 2016. This draft was reviewed again by Mr Standen, Mr Standen has indicated
that version 1 of the Draft E&SCP also does not meet the Wellington Guidelines because the sediment
retention ponds (SRP's) Ilave been proposed to be si~ed at 0.5 percent and batch dosed, rather than
having floc blo(;ks permilnently installed on the SRP. Section 51 (g) of the Wellington Guidelines states
that only SRP's with permanent fJoc blocks installed can be sized down to 0.5 percent of the contributing
catchment.
While the draft E&SCP v1 does not meet the Wellington Guidelines, a final E&SCP will need to be
submitted for certification as part of the recommended conditions of consent. On-site management of
erosion and sediment effects ,lI1d potential adverse effects on watercourses will then be managed
throullh the implementation of certified Erosion and Sediment Control Plan (E&SCP), It is anticipated that
the applicant wiil build on the draft document submitted as part of the s92 request and amend as
required in order to manage the effects associated with this application.
In addition to the controls and measures undertaken in the (E&SCPl, the applicant will need to regrass
and stabilise areas of bare earth as soon as possible following the completion of each sequence of works
i.e. at the end of each construction season. As long as the works are undertaken in accordance to design
standard, in accordance with a certified Erosion and Sediment Control Plan (ESCP), and In accordance
3

with the recommended conditions of consent the overail site stability should improve a, a result of the
works.
