DRAFTHurunui District<strong>Important</strong> <strong>Natural</strong> <strong>Landscapes</strong>LANDSCAPE ADVICE FOR DISTRICT PLAN REVIEWDRAFT FOR CONSULTATION
PREPARED FOR HURUNUI DISTRICT COUNCIL (HDC)BY BOFFA MISKELL LIMITEDDRAFT REPORT FOR CONSULTATIONMARCH <strong>2013</strong>LANDSCAPE ADVICE FOR DISTRICT PLAN REVIEW
6IntroductionHurunui District Council (HDC) has engaged <strong>Boffa</strong> <strong>Miskell</strong> (BML) landscape planners to provide advice on landscaperelated aspects of their District Plan review. This report has been prepared by BML Landscape Planner Yvonne Pfluger toassist with identification of important landscapes under sections 6(a) and 6(b) of the RMA for the proposed HurunuiDistrict Plan.We have undertaken a preliminary review of the Outstanding <strong>Natural</strong> <strong>Landscapes</strong> (ONLs under RMA s6(b)) currentlyidentified in the Hurunui District Plan as part of a previous stage of work. We concluded that generally the existing areasare appropriate. We understand that the Council may not require a detailed review of all existing Outstanding <strong>Natural</strong>Features and Landscape (ONF/L) boundaries, if they are not intending to change these boundaries unless challengedthrough the review or in response to specific requests in submissions. However, as requested by HDC, we undertook adetailed review of three particular ONF/Ls, namely the identification of Mt Cass as an ONF, the review of the Main DivideONL and a specific boundary review of the south western corner of the Waipara Gorge ONL. The option of undertaking adesktop review of all ONF/L boundaries will be discussed with Councillors at the upcoming workshop.While it is not considered necessary to have identical outlines for ONLs in the region (Regional Policy Statement/ RPS)and districts (District Plans), we noted that the areas are largely aligned in this case and seem to be appropriate whenassessed on a district-wide scale.In addition to this limited ONF/L review, HDC was also seeking advice onnatural character and landscape issues in itscoastal environment to fulfil the requirements under the New Zealand Coastal Policy Statement (NZCPS, 2010). Thisincludes the identification of the coastal environment and an assessment of itsnatural character values in order toidentify the coastal areas that may be considered as having high or outstanding natural character under the NZCPS2010. The areas in the coastal environment identified d as outstanding interms of their natural character are referred to as“Outstanding <strong>Natural</strong> Character Areas” (ONCs).The landscape as we see it today is a product of both natural processes and several centuries of human occupation.Ongoing land use change and constantly evolving agricultural practices reflect economic efficiency and human needsat the time. <strong>Landscapes</strong> are dynamic and will continue to evolve, while both natural and cultural features remain asDRAFTevidence of past processes. While it is difficult to anticipate future land use development and pressures for changein the landscape, it is considered essential to provide for human needs as well as sustainably manage the existinglandscape values. This report helps to identify the sensitivities and values of the Hurunui landscape that require a levelof protection from inappropriate subdivision, use and development. While this does not mean that landscape changein general may be inappropriate in these areas, it is likely that the outstanding landscapes identified in this report aregenerally more vulnerable to extensive human intervention and have lower ability to absorb change than other rurallandscapes.Large-scale land use change, such as development of subdivisions, forestry plantations, substantial earthworks andnative vegetation removal, have an impact on the landscape that extends beyond the immediate surroundings. Theintroduction of man-made elements in the form of structures and the creation of unnatural patterns and lines canlead to degradation of the existing visual quality and landscape/ natural character values, such as intactness of legiblelandforms and native vegetation cover. The district plan aims to manage these irreversible impacts on the landscape andnatural character values within its special landscapes, including ONLs and Coastal <strong>Landscapes</strong> with outstanding naturalcharacter, in a sensitive manner. The findings of this report in relation to landscape and natural character sensitivitieswill inform the review of the relevant rules in the district plan, which provide guidance for potential landscape change.Hurunui District | <strong>2013</strong>
Statutory Context and LandscapeManagementAll landscapes arguably merit some management consideration under the ‘sustainable management’ purpose of theRMA and the requirement to avoid, remedy or mitigate adverse effects of activities on the environment. From a technicallandscape perspective, the purpose of management may be characterised as:a) avoiding the inappropriate erosion of the intrinsic characteristics and qualities that have built up in the landscape overtime through the interplay of natural and cultural processes; andb) enabling development and change to occur that avoids the loss of landscape coherence, diversity and cultural identityand meaning.7SECTION AThis landscape perspective is packaged within the RMA under a number of matters of national importance (RMA Section6) and other matters to which the Council is required to have particular regard (Section 7). The key sections of the RMAthat relate to landscape are: ‘Protection of areas of significant indigenous vegetation and significant habitats of indigenous fauna’ (Section 6(c)) and‘the relationship of Maori and their culture and traditions with their ancestral lands, water, sites, wahi tapu, and othertaonga (Section 6(e)) are also clearly linked to a broad understanding and valuing of landscape.<strong>Natural</strong> features and landscapes that do not meet the criteria for being ranked as “outstanding” can nonetheless qualifyfor protection under other clauses in S.6 or be required to be “maintained and enhanced” either as “amenity values” orpart of the wider “environment” under S.7(c) or S.7(f). Thus, for example, coastal landscapes or rivers or lakes that werenot “outstanding landscapes” would still be required to have their “natural character” preserved under S.6(a), or areas ofindigenous vegetation or habitats of indigenous fauna that were not considered “outstanding natural features” underS.6(b) will require protection under S.6(c).DRAFTLarge areas of the western part of Hurunui District are within DOC ownership, including the Main Divide ONLs (ie withinmajor river valley, mountain ranges and main divide landscape types), but the low land landscapes are predominantly inprivate ownership and potentially vulnerable to change.As part of the District Plan Review, it is recommended that the objectives, policies and rules be reviewed andstrengthened to ensure that an adequate level of protection is provided for the District’s important landscapes. Thehighest level of protection would be warranted for those areas that are identified as “outstanding” under sections6(a) and 6(b) of the RMA, in other words the ONF/Ls and ONCs within the District. It is our understanding that HDC isnot considering the introduction of a second tier landscape protection under S.7(c) at this time. However, we wouldrecommend specific landscape management mechanisms be developed for the Coastal Environment within the district,to meet the requirements of the NZCPS, even though this landscape is generally more modified than the ONCs.Hurunui District | <strong>2013</strong>
8Hurunui Outstanding<strong>Natural</strong> Features and<strong>Landscapes</strong>BackgroundThe findings in the study “<strong>Landscapes</strong> of the Hurunui District” prepared by Lucas Associates (1995) formed thebasis for ONL identification in the Hurunui District Plan. Most areas identified in the study have been carried overinto the formal recognition through the plan. The Conway Flats are the only notable omission. However, boundaryadjustments were undertaken for some of the other areas as part of landowner negotiations and submission/appeal processes.The Regional ONLs identified within the Canterbury Regional Landscape Study Review (BML, 2010) are generallysimilar to those in the Hurunui District Plan. It is to be expected that ONLs between the Region and District are notidentical, as they were undertaken at different scales and within a different context. There is a complex relationshipbetween the status "outstanding" and the scale at which an evaluation is made. District landscape studies areundertaken within the district context and are refined in accordance with the statutory processes for DistrictPlan preparation. It is our understanding that some small differences in boundary outlines are due to individuallandowner agreements following detailed assessments. It is acknowledged thatthe identified Outstanding <strong>Natural</strong><strong>Landscapes</strong> vary in land cover and landscape quality.Methodology for LandscapeRecognitionin the Current Hurunui District PlanIn accordance with the Hurunui District ict Council's background report, “Landscape Values: Literature Review” (1994),the definitions and criteria developed in the Canterbury Regional Landscape Study (1993) were adopted in the1995 “<strong>Landscapes</strong> of the Hurunui District” Report."Landscape" has thus been used to encompass both the physicalexpression of the land and a reflection of the values people place on the land. In the context of the District, foridentification as "outstanding", a landscape would need to have exceptional characteristics or values with regard toat least one of these criteria (see Appendix 2 for definition of those 1995 criteria).DRAFTThese criteria applied for the 1995 Hurunui Landscape Study are a set of values which have subsequently beenestablished and modified by case law over the years, and are known as the ‘Amended Pigeon Bay Criteria’ (egC180/1999 - Wakatipu Env. Society v QLDC). There is now a level of acceptance of their use as an assessmentframework within the landscape planning profession. The criteria used for the 1995 Hurunui Landscape Study arestill applied in today’s context and we therefore consider the assessment methodology remains appropriate androbust.The following criteria are a more recent evolution of those used in 1995, and have been used as a basis to structurethe evaluation of each landscape character type/ unit in relation to this current study:The natural science factorsThe geological, topographical, ecological and dynamic components of the landscapeIts expressiveness (legibility)How obviously the landscape demonstrates the formative processes leading to itIts aesthetic values including memorability and naturalnessTransient values - occasional presence of wildlife; or its values at certain times of day/ yearWhether the values are shared and recognisedIts value to tangata whenuaIts historical association.Hurunui District | <strong>2013</strong>
The values listed above may be grouped as biophysical, sensory and associative qualities and each group requiresparticular management techniques. There are various different ways in which landscapes may be appreciated andwhich may help determine thresholds of quality.In recent decisions (eg EC C387/2011 – PC13 Mackenzie Basin) the Courts have indicated that ‘natural’ in thecontext of landscape identification under RMA section 6(b) does not signify ecological intactness. Modifications toendemic naturalness can still be perceived as natural. Based on findings in case law over recent years, thresholdsfor identifying ONF/Ls have changed, as have landscapes in terms of their qualities.The identification of ONLs in the current district plan was undertaken at a district scale, but mapping accuracy atthe time of preparation of the Hurunui Landscape Study (1995) was lower than what can be achieved nowadayswith modern Geographic Information Systems (GIS). GIS allows the assessor to zoom in and determine a moreaccurate location of landscape boundaries. While broad geographical features have been included in the 1995ONLs which have been mapped on 1:50,000 topographical maps, there is potential for boundary refinement basedon recent aerial photography. It should be noted that the limited ONF/L review provided in this report has onlybeen undertaken as a desktop study, including analysis of GIS data on land cover and aerial photos.9SECTION BStatus of ONFLs in District PlanProposed additions to ONFLsExisting ONFL Operative Hurunui District Plan0 5 10 20 Km° NMap showing ONF/Ls in Hurunui District as proposed following this landscape review. The three areas, where changesto the current Plan are proposed, are shown on the following pages.Hurunui District | <strong>2013</strong>
10Mt CassOutstanding <strong>Natural</strong> Feature/ LandscapeMt Cass is located in the Waipara Basin, approximately 10 km north-east of Amberley. Mt Cass is one of three peaks on adistinctive cuesta landform, an asymmetric ridge of limestone rock outcrops. Totara and Oldham Peak are located alongthe ridge to the northeast. Typical of this type of landform Mt Cass has a steep north-west facing scarp slope and a gentlesouth-eastwards dipping backslope.Mt Cass was not identified as an Outstanding <strong>Natural</strong> Landscape in the Hurunui Landscape Study (Lucas Associates,1995). However, in a decision concerning a wind farm proposal on Mt Cass the landform was considered to be anOutstanding <strong>Natural</strong> Feature (ONF). In the Environment Court hearing considerable and detailed evidence on the questionof whether Mt Cass ridge is an ONF was presented. Between experts there was general agreement on its local significanceto the Waipara landscape. The Commissioner’s view that Mt Cass qualifies as an ONF was upheld in the EnvironmentCourt decision (EC C384/2011) released in 2011. The court concluded that the ridge feature between Mt Cass and TotaraPeak is distinctive within the wider landscape and is an ONF.For the preparation of this report we analysed the EC decision to determine the extent of the ONF for adoption into theDistrict Plan. The following paragraph of the decision gives guidance in relation to the location and extent of the ONF:[323] The Hurunui Commissioners concluded that Mt Cass ridge (that part of the site between Mt Cass and Totara Peakincorporating the limestone platforms, the native woody vegetation and thelimestone escarpment) is an outstandingnatural feature for the purposes of section 6(b) of the Act. 255 Ms Lucas and Ms Briggs agree that there is an outstandingnatural feature at Mt Cass, and that the escarpment is an integral part of the limestone landscape feature, as do the twogeomorphologists. Ms Lucas goes further to include the northern most extent of the ridge terminating at Oldham Peak,thus indicating a larger feature than had the Commissioners.In order to fully understand the extent of the ONF we also reviewed the evidence of the Council landscape witness, whoserecommendations were adopted (Liz Briggs) gs) and her graphic attachment which illustrates indicative outlines for the ONF.In her assessment against section 6 (b) of the RMA (para58-80) Liz Briggs concluded that (Para 73) “the Mt Cass landform,as illustrated and defined in Appendix pendix 2 and Appendix 3 constitutes an Outstanding <strong>Natural</strong> Feature. This is based on:DRAFT feature is of regional significance.”Based on this assessment we identified the extent of the ONF shown in the map on the facing page. On-siteinvestigations to confirm findings are yet to be organised (Site visit with Helga Rigg(Hurunui District Council) and AndrewHurley (Mainpower)).The images above informed the ONF identification, see Liz Briggs' EC evidence (prepared by Lucas Ass.)Hurunui District | <strong>2013</strong>

12Main DivideOutstanding <strong>Natural</strong> Feature/ LandscapeWhile we have not been asked to undertake a detailed review of all existing ONL boundaries, as currently shown in theDistrict Plan, they generally align with the ONLs identified in the Canterbury Regional Landscape Study. However, twoanomalies in the western part of the District were identified, where areas were excluded from the wider ONLs. Theseareas are located:a) around Philosophers Knob within the St James Conservation Area (surrounded by St James walkway) andb) around the headwaters of Hope, Doubtful, Nina Rivers (south of Lewis Pass within Lake Sumner Forest Park andtwo smaller conservation areas).Both of these areas were originally identified as significant landscape areas in the proposed Hurunui District Plan. A reviewof the 1995 landscape assessment (prepared by Di Lucas) was carried out by Allan Rackham of <strong>Boffa</strong> <strong>Miskell</strong> in 1999.This review again identified the Philosophers Knob area as a significant landscape. The Lewis Pass/Lake Sumner area wasnot included in this review. We note that the Wilkinson court decision (Wilkinson v Hurunui District Council C050/2000[2000] NZEnvC 78 (29 February 2000) led to the removal of significant landscape areas from the Plan.Since then these areas have been retired from farming and included in the Department of Conservation (DOC) managedconservation estate. This means that land cover regeneration is occurring in these areas and both their biophysical,sensory and associative qualities have improved since ONLs were identified for the currently operative district plan. Weconsider that these areas are of similar landscape quality in terms of their values and naturalness to the surroundingONLs. We, therefore, recommend that these areas are included into the surrounding ONLs from a technical point of view.While both of these areas are now owned by the Department ent of Conservationand therefore have public conservationland status, we consider additional protection through ONL identificationappropriate.HDC has discussed this matter with DOC (Waimakariri and Nelson/Marlborough Area offices) who have indicatedtheir full support for the inclusion of the areas as ONF/Ls. Smaller additions of DOC managed land have occurred alongthe tops of the Hanmer Range, land retired ed from Hossack Station (north of the upper Lottery River headwaters) andthe southern part of the Ka Whata Tu o Rakihouia Conservation Park around Mt Horrible, which extends into KaikouraDistrict.DRAFTHurunui District | <strong>2013</strong>

14Waipara GorgeOutstanding <strong>Natural</strong> Feature/ LandscapePrior to commencing the review of their district plan, HDC have been requested by Claremont Farms to review theexisting south western boundary of an ONL in the upper Waipara catchment. We have been provided with thecorrespondence between the farm owner and HDC and reviewed the maps attached to his letters. It appears that theproposed QE2 area referred to in the correspondence on the land in question has not been approved yet, as it does notshow in the QE2 GIS database.We reviewed the ONL boundaries in the area and concluded that there is potential for the outlines to be refined. Ourreview resulted in a recommendation to exclude some of the highly modified farm land along Ram Paddock Road. Inour opinion, the key landscape values are provided by the limestone features and the vegetated river bed and gullies(contained by steep limestone cliffs).We recommend the inclusion of the limestone feature as a whole (not just theoutcrop at the top) to ensure that the integrity of the landform is maintained.Furthermore, we also recommend inclusion of several vegetated gullies and limestone cliffs along the Waipara River,some of which are DOC land. While the ONL area may slightly increase overall based on these recommendations, it ismore confined to the gullies and ridgelines and excludes the more intensively farmed flats.As part of reviewing the ONL boundary situation at Claremont Farms, we found, based on our GIS desktop review, thatthere is potential for further ONL boundary refinement in other areas ofthe Waipara/ Weka Pass ONL. We recommendthat this GIS desktop review is undertaken at a scale of 1: 25.000 on aerial photofor the remainder of that area. Thiswould help to ensure that the limestone features are adequately included inthe ONL and some of the intensivelyfarmed areas that do not form part of the landform are excluded. Such desktop review of the boundaries of the ONLsis recommended across the wider District now that more detailed information is available than it was at the time ofdeveloping the current ONL boundaries. This is a matter for further discussion with the Council.We understand that any other potential ONL issues will be addressed through the submission process, which mayrequire further landscape assessment sment work at a laterstage in the District Plan review process.We reviewed the Geopreservation Inventory for the areaand confirmed that three sites adjacent to the identifiedONL that have not been included. We recommendinclusion of the following three Geopreservation Sites inthe ONL (see Appendix 3 for description):31(1)Deans Earthflow complex (between the Deans andWaipara River),2(2)Waipara River Cretatous Paleocene Sequencebluffs on south bank about 0.7km upstream fromLaidmore Station Road crossing, Waipara Riverbetween Doctors Gorge and junction with BirchHollows Stream),Geopreservation sites at the Waipara Gorge.(3)Waipara River Saurian beds (just downstream of siteNo 2 in Waipara River)Hurunui District | <strong>2013</strong>

16Coastal Environment and<strong>Natural</strong> CharacterBackgroundBML was involved in a region-wide coastal assessment project commissioned by Environment Canterbury (ECan) in2011. The ECan project was completed to a first draft stage, which included delineation of the coastal environment(peer reviewed) and the natural character descriptions (not- peer reviewed). While the region-wide study has notbeen finalised and publicly released, ECan has made the work to date available to HDC internally for their district planreview. ECan provided the existing desktop information from the project, including an extensive record of oblique aerialphotographs and data, for further analysis on a district-wide level.The tasks involved in the Coastal <strong>Natural</strong> Character Assessment for HDC were the identification and delineation of thecoastal environment, an assessment of the natural character of the coastal environment and identification of Areasof Outstanding <strong>Natural</strong> Character (ONC, see Policy 13a of the NZCPS). These tasks resulted in an evaluative report andaccompanying GIS maps (see following section) that identify areas of high, very high and outstanding natural character.The ONCs identified in this report are a result of both (1) the extent of the coastal environment and (2) the degree ofnatural character.We would recommend that the evaluative part of the coastal natural character assessment for HDC, including the outlinesof areas of Outstanding <strong>Natural</strong> Character, is reviewed by an external peer reviewer prior to this report being madepublic.New Zealand Coastal Policy StatementThe recent release of the new Coastal Policy Statement (NZCPS 2010) has highlighted the need for identification andmapping of special landscapes occurring curring within the coastal environment. Policies 13 and 14 of the NZCPS (2010) havebeen dedicated to the preservation and restorationof natural character. This includes the identification and protectionof coastal landscapes with high, very high or outstanding natural character . While outstanding natural landscape areashave been addressed in the operative Hurunui District Plan, areas of high natural character have not been specificallyidentified or provided for.DRAFTThe NZCPS 2010 requires councils to assess the natural character of the coastal environment of the region or district, bymapping or otherwise identifying at least areas of high natural character (Policy 13- 1(c)).Therefore, following the release of the NZCPS, an assessment of natural character along the Hurunui Coastline andidentification of areas with high and outstanding natural character was required. It was considered appropriate to (1)determine the inland extent of the coastal environment, (2) determine the degree of coastal natural character presentand (3) identify the spatial extent of any specific preservation or protection ‘zones’ necessary.The Coastal Policy Statement also covers the protection of historic heritage in the coastal environment and highlightsthe need for integrated management not only of historic sites, but also their context. It requires councils to initiateassessment and management of historic heritage in the context of historic landscapes . This matter is dealt withseparately within the District Plan review.Hurunui District | <strong>2013</strong>

18Protection of Coastal <strong>Natural</strong> CharacterSome landscapes that fall within the coastal environment will have natural character that may justify additionalprotection beyond that afforded to other rural landscapes (this will also apply to rivers, wetlands, lakes and their margins).The RMA in s6(a) does not specify a level of quality.Policy 13 of the NZCPS outlines the requirements in relation to the preservation of natural character as follows:(1) To preserve the natural character of the coastal environment and to protect it from inappropriate subdivision,use, and development:(a) avoid adverse effects of activities on natural character in areas of the coastal environment with outstanding (b) avoid significant adverse effects and avoid, remedy or mitigate other adverse effects of activities on natural This highlights that the need for protection from inappropriate subdivision use and development may apply to alllandscapes within the coastal environment but this will also relate strongly to the degree of natural character present. TheONCs provide values that make them “stand out” from the remainder of the coastal environment in terms of their naturalcharacter, and a higher level of protection is therefore warranted.Methodology Coastal <strong>Natural</strong> Character StudyDefining the Coastal EnvironmentThe RMA 1991 does not define ‘coastal environment’. However, to respond to Policy 1 of the NZCPS 2010: ‘Extent andCharacteristics of the Coastal Environment’ it was necessary essary to adopt a definition. Policy 1 recognises that the extent andcharacteristics of the coastal environment will vary from location to location and identifies nine characteristics which maybe included in the coastal environment:a) The coastal marine area;b) Islands within the coastal marine area;c) Areas where coastal processes, influences or qualities are significant, including coastal lakes, lagoons, tidalestuaries, salt marshes, coastal wetlands, and the margins of these; (Study Team emphasis)d) Areas at risk from coastal hazards;DRAFTe) Coastal vegetation and the habitat of indigenous coastal species including migratory birds;f) Elements and features that contribute to the natural character, landscape, visual qualities or amenity values;g) Items of cultural and historic heritage in the coastal marine area or on the coast;h) Inter-related coastal marine and terrestrial systems, including the intertidal zone; andi) Physical resources and built facilities, including infrastructure, that have modified the coastal environment.however, the list does not provide an answer in how to define this environment.Through the development of a methodology to determine the extent of the coastal environment, BML were guided by allof the identified characteristics, although gave particular consideration to item (c) of Policy 1(2) of the NZCPS 2010 ‘wherecoastal processes, influences or qualities are significant’. This, along with the relationship to the accompanying naturalcharacter study provided helpful guidance. All other characteristics of the coastal environment were also addressed in themethodology.The term ‘significant’ is not defined in the NZCPS 2010. Within the context of the RMA 1991 the word is used to addressSection 6(c) matters. In the context of Policy 1(2)(c) of the NZCPS 2010, the study team have interpreted the termEnglish Dictionary.Hurunui District | <strong>2013</strong>
19The seaward extent of the coastal environment extends 12 nautical miles from MHWS and is administered byEnvironment Canterbury. However, whilst Motunau Island is situated in Environment Canterbury's jurisdiction (seawardof the MHWS) it is part of the Hurunui District's responsibility. Although the Hurunui coastline is, for the majority of itslength, generally uniform, specific attention needs to be given to more complex areas, including Gore Bay, river mouthsand areas of bays and beaches.A general rule of thumb is that the inland extent of the coastal environment extends to the first [proximate] significantridgeline inland of the coast, although for flat areas, the boundaries are determined more by landscape character andwhere coastal elements, patterns and processes are still sufficiently significant. The ‘first ridge’ concept has recently beendiscussed in the Mt. Cass Environment Court decision regarding a wind farm proposal:“[320] The Hurunui Commissioners, referring to case law, were persuaded that the coastal environment boundary shouldbe at the dominant landward ridge, which they identified as Mt Cass. We accept that Mt Cass is a dominant ridge andthat glimpses of it can be seen from some parts of the Hurunui coastline. In other cases before the Environment Courta landward ridge has been adopted as a boundary to a coastal environment. However, where a dominant ridge maybe a useful means to identify a coastal environment boundary, such a boundary should be relevant to the coastlineand coastal environment. There is no necessity to identify a dominant ridge in each case, particularly one that may bekilometres away from the coast. In any event we are satisfied that the effects on natural character and landscape wouldnot extend to that area which could properly be considered to be coastal environment of Hurunui.[321] We find that Mt Cass ridge and the dip slope landward of the ridge is not within the coastal environmentand neither is any part of the wind farm. By contending that the coastal environment has an extreme reach, we areconcerned that attention could be drawn from the importance of the coastline and derogate from the focus of section6(a).”Fundamental to this assessment of the Coastal Environment nt is the relevant and accessible data available to informjudgements. This is listed in the Mapping Information on section. The use ofprofessional knowledge of the study teamin relation to the elements outlined within Policy 1 of the NZCPS 2010 was also an essential source of information.Few components listed under Policy 1 have been excluded, whichinclude cultural and historical aspects and benthic/bathometry studies, since limited information was available.The mapping and assessment scale for this task is ‘for thedistrict’.Mapping InformationDRAFTThe scale of the natural character study is critical to the validity of the end results. As outlined earlier, natural characterassessment is scale related and determined by the study brief and to varying extents by the mapping scale of the informationused to determine the outcomes of the project. For this project, the scale is the region, although as describedearlier, mapping is at a district level.SECTION CThe assessment was primarily based on a desktop study and an aerial survey with limited ground-truthing. GIS hasbeen used to systematically map the extent of the Coastal Environment and to map coastal areas. The mapping scaleundertaken for this project is 1:50,000. It is acknowledged that the majority of the data used for this study is at scalesgreater than 1:50,000. The mapping has been undertaken on high resolution aerial images, although presented in thisreport on 1:50,000 topographical maps. Where more intricate sections of the coastline exist, these have been mappedat a finer scale. At these finer scales, GIS allows the viewer to zoom in and assess the exact location of the coastalenvironment. However, extent of the coastal environment and coastal area boundaries in this study were mapped withinthe context of the Canterbury region as a whole and with reference to surrounding broad geographical features, notpaddock by paddock. This broader context should be borne in mind. For a list of GIS information refer to Appendix 4.Hurunui District | <strong>2013</strong>

21The Coastal Environment – Zones of SignificanceBML has developed the following model which has been applied to the Hurunui coastline in order to determinethe Coastal Environment, as interpreted under Policy 1 of the NZCPS 2010. Essentially the Coastal Environmentcontains two zones of significance:The Coastal Environment and the Coastal Context Zone can collectively be referred to as The Coastal LandscapeThe two diagrams (opposite) illustrate the extent of the Coastal Environment and the three zones in two verydifferent types of coastal areas: one a steep coastal area and the second a flat coastal area. The diagrams illustratethat the coastal environment is determined by a variety of factors and changes from one coastal area toanother.SECTION CZone AThis zone includes the CMA and the Active Coastal Interface Zone. The CMA includes the sea,rocks and part of the beach up to the mean high water spring (MHWS) mark and extends outto sea for twelve nautical miles*. The Active Coastal Interface is where the sea is the dominantelement, and the primary or significant influence on landform, vegetation, and perception. TheActive Coastal Interface varies in width, but generally extends inland of the MHWS mark andcomprises the inter-tidal area above MHWS, beaches, lagoons, estuaries and their margins, rockypeninsulas and coastal cliffs.Zone BThe Coastal Significance Zone generally includes the land up to the first coastal ridge or escarpment(with the width of this zone varying depending on the topography environment. This zoneis where coastal processes are significant and may include inland cliffs, settled (or modified)dune lands, farm land, settlements and coastal forests.Both zones contain and exhibit coastal processes, influences and qualities that are significant.Inland, beyond the Coastal Environment, is a third area, where coastal processes, influences and qualities arenot significant but form part of the coastal landscape:Zone CThe Coastal Context is where coastal processes inland of the Coastal Environment have anDRARAFTinfluence on the landscape and would include developed back-dunes which no longer exhibitsignificant coastal processes, coastal plains, and containing hill-slopes. This zone generallyextends inland from Zone B to where coastal influences have sufficiently diminished. It is alsorecognised that some activities occurring within this zone can significantly affect the coastal environment(Zones A and B) either perceptually or physically to varying degrees. The inland extentof Zone C has not been mapped, as it falls outside of the Coastal Environment.*The seaward extent of the coastal environment extends 12 nautical miles from MHWS and is administered by EnvironmentCanterbury. However, whilst Motunau Island is situated in Environment Canterbury's jurisdiction (seawardof the MHWS) it is part of the Hurunui District's responsibility.Hurunui District | <strong>2013</strong>
22Coastal <strong>Natural</strong> CharacterEnvironments with the greatest natural character are those devoid or virtually devoid of human modification andare therefore composed of natural elements appearing in natural patterns and underpinned by natural processes.<strong>Natural</strong> character is not defined in the RMA or in the NZCPS 2010. There are various working definitions of theconcept which are broadly similar and have been used in a number of Environment Court cases. In light of theNZCPS 2010, the definition was also discussed at the first of two workshops convened by DOC in August 2011to discuss potential guidance material in relation to Policy 13 and 14 of the NZCPS. This workshop, attended bylandscape architects, DOC and local authority personnel and other environmental practitioners discussed anddebated the term and its origins. Building on a previous definition from the Ministry for the Environment (MfE), theworkshop confirmed acceptance of the following definition, which is both useful and workable:<strong>Natural</strong> Character is the term used to describe the natural elements of all coastal environments. The degree or levelof natural character within an environment depends on:4. The effect of different types of modification upon natural character varies with context and may be perceiveddifferently by different parts of the community’This interpretation is referenced to varying degrees in Policy 13 of the NZCPS 2010.Within the ‘Long Bay’ Environment Court decision , the court built upon the ‘Outstanding <strong>Natural</strong> Featuresand Landscape’ definition of naturalness outlined within the ‘Wakatipu Environmental Society Incorporated vQueenstown Lakes District Council’ . Although specifically relating to ‘natural’ under Section 6b (of outstandingnatural landscapes), paragraph 135 of the Long Bay decision states the following definition of ‘natural’:‘The absence or compromised presence of one or more of these criteria does not mean that the landscape orcoastal environment is non-natural, just that it is less natural. There is a spectrum of naturalness from a pristinenatural landscape to a city scape, and a ‘cultured nature’ landscape may still be an outstanding natural landscape.’ DRAFTSince the development of the MfE definition, and the ‘Long Bay’ decision, the NZCPS 2010 has come into effectwhich states (Policy 13) that natural character may include:(a) natural elements, processes and patterns;(b) biophysical, ecological, geological and geomorphological aspects;(c) natural landforms such as headlands, peninsulas, cliffs, dunes, wetlands, reefs, freshwater springs andsurf breaks;(d) the natural movement of water and sediment;(e) the natural darkness of the night sky;(f) places or areas that are wild or scenic;(g) a range of natural character from pristine to modified; and(h) experiential attributes, including the sounds and smell of the sea; and their context or setting.Recognising a lack of guidance for the implementation/interpretation of the NZCPS 2010, BML held a two-day inhouseworkshop in early 2011 to develop a consistent approach to natural character assessment and interpretationof NZCPS 2010 terms. At the BML 2011 workshop, it was evident that ecologists’ and landscape architects’ views of‘natural’ and ‘naturalness’ are complementary yet sufficiently different to warrant further clarification. Ecologistsinterpret natural character in terms of indigenous attributes, whereas landscape architects take a broader viewthat can encompass both indigenous and exotic natural attributes. Accordingly, the thresholds differ and a refineddefinition of ‘naturalness’ was agreed as being:Hurunui District | <strong>2013</strong>
23i) Ecological naturalness (indigenous nature); and Through the BML 2011 workshop, participants were able to develop a consistent company-wide assessmentapproach that incorporates both landscape and ecological expertise as well as taking into consideration the ‘MfEdefinition’, case law (including the ‘Long Bay’ decision), and those definitions developed in the NZILA Best PracticeNote 2010 . The assessment approach is based upon an agreed interpretation of key terminology, and includes amethod for determining the inland extent of the Coastal Environment (refer to the Coastal Environment discussionabove) as well as an assessment matrix and evaluation methodology for identifying ‘high’ and ‘outstanding’ naturalcharacter (as required by Policy 13 of the NZCPS 2010). <strong>Important</strong>ly, the BML methodology can be adapted to suitdifferent types and scales of coastal landscapes.SECTION CFor the purposes of this project, the following key points are noted: Limited input on ecological values was provided by BML ecologists. Marine ecology information was providedthrough Department of Conservation publications. That natural character assessment is context and scale related, so that the coastal environment can beperceived as having different levels of natural character at different scales, because the level of detail thatcan be discerned and the dominant attributes that are displayed vary according to the scale at which theyare considered. Similarly, a proposal can have different effects on natural character when the surroundingenvironment is considered at different scales. For the purposes poses of this assessment, the scale assessed is at the That natural character occurs on a modification continuum and describes the expression of natural elements,patterns and processes (or the ‘naturalness’) in a landscape where the degree of ‘naturalness’ depends on: The fact that the highest degree of natural character (greatest naturalness) occurs where there is least The fact that the degree of natural character is fluid and can change over time.DRAFTSignificant rocky reefs occur around the limestone outcrops at Napenape where impressive rock platforms protrude inparallel bands for over 100m from the shore.Hurunui District | <strong>2013</strong>
24<strong>Natural</strong> Character Assessment and Key IndicatorsThe degree or level of natural character has been, for the purposes of this study, ranked on a seven-point scale:Very High (lowest amount of modification), High, Moderate to High, Moderate, Moderate to Low, Low and VeryLow (greatest amount of modification). In accordance with the requirement outlined within Policy 13 of the NZCPS2010, at least areas of high natural character have been mapped. For completeness, all coastal areas have beenmapped according to their degree of natural character (i.e. very low through to very high). The rateable ‘degree’of natural character for each coastal area were obtained by amalgamating the ‘values’ assigned to each of thefive attributes assessed as listed in the table below. The ratings for each coastal area were considered in a districtcontext, therefore an area holding high natural character holds that rating value at a district scale, not at a regionalor national scale.As part of this study, the Hurunui coastline has been divided into 12 coastal areas that share a similar characterand are broadly homogenous. Coastal areas range in length and overall size, depending on type of coastline andvariation of landscape character. Some coastal areas may contain smaller ‘highlights’ such as headlands or rivermouths, but are an integral component of the broader coastal area.Coastal Areas and the Coastal Environment Assessment MatrixIt is acknowledged that there are a number of key attributes that need to be considered when assessing the naturalcharacter of the coastal environment. Through BML’s experience and the interpretation of the NZCPS 2010, thefollowing attributes have been identified which consider/ reference the different aspects of the natural patterns,processes and elements of the coastal environment and the degree e of modification present. All aspects are coveredwithin Policy 1 of the NZCPS 2010 and some further refinement of the list may berequired:WaterAbioticSystems andLandforms[Zone A]. Includes the water body of the CMA (including surf breaks) and landforms withinthe Active Coastal Interface and below MHWS (e.g. rocks, reefs, stacks, channels). Alsoincludes habitats, ts, biota and naturalprocesses within Zone A. This excludes water-bodiesabove MHWS (or those contained within Zone B). Considers the degree of modificationDRAFTFTsuch as changed water courses, earthworks, presence of built structures, (moorings, jetties,marine farms, and navigation structures), and dredging.[Zones A & B.] Abiotic systems, including the degree of activeness of the tide, waves andcurrents as well as wind, landform and terrestrial coastal formation, erosion, river mouthprocesses including sedimentation. Geomorphology, identification of different types oflandforms and landforming processes (e.g. dunes, wetlands) and the physical modificationsto these natural landforms such as built structures, road cuts, earthworks and reclamationworks are also an important component of this attribute.Perceptual &experientialTerrestrial &aquatic(Biotic Systems)Land Cover &Land Use[[Zones A & B]. <strong>Natural</strong> attributes regarding the experience in seeing/feeling/ and perceivingthe coastal environment.

The attribute tablehas been developed to avoid double-counting and to ensure e that the indicators for each attribute are mutually exclusive.There are, however, overlaps between some attributes, tes, which is reflected in the descriptions for each coastal area. Eachattribute has been considered equally, with no weighting applied.The degree of natural character for each coastal area was then assessed, based on an aggregation of the values. Thestudy team acknowledge that not all attributes within each coastal area need to score ‘high’ to hold an overall ratingof high. In some instances a coastal area which rates highly overall, may only have a few attributes holding high or veryhigh ratings. While the study team tried to maintain a high level of objectivity throughout this process, professionaljudgment was involved in the determination of the thresholds. This was based on a rigorous analysis of the dataavailable and a carefully crafted methodology. Whilst in some instances the overall natural character rating for a coastalarea was obvious (i.e.it fell at either end of the continuum), particular consideration arose around areas those areasholding ‘moderate‘ ratings.HIghDRAFTSECTION CFurthermore, Zone C has also been considered, as it is acknowledged that elements within this zone can also affect thenatural character of the coastal environment. No value system has been ascribed to Zone C, only a description.Hurunui District | <strong>2013</strong>
26Outstanding <strong>Natural</strong> CharacterUnder RMA s6(a) it is necessary to determine the existing attributes and extent of natural character and assesshow these will be affected by a specific proposal. This approach is also required under the NZCPS 2010. However,Policy 13 of the NZCPS 2010 also specifically requires that an evaluation is made as to whether the natural characterin the existing coastal environment is outstanding or not (in order to determine whether Policy 13(1)(a) or 13(1)(b) is triggered). Policy 13(1) of the NZCPS 2010 states:(1) (a) avoid adverse effects of activities on natural character in areas of the coastal environment withoutstanding natural character; and(b) avoid significant adverse effects and avoid, remedy or mitigate other adverse effects of activitiesAn area with outstanding natural character may be an area within the coastal environment that is considered tohave high or very high levels of natural character, although it is important to note that the high or very high ratingsdo not equate in themselves to ‘outstanding’.The following definitions were established and agreed at the BML 2011 internal workshop:others in the same study context.‘Outstanding <strong>Natural</strong> Character’: The coastal environment may be outstandingwhere it has high or very high levelsof natural character.It was determined by the study team that outstanding natural character should be assessed separately. An assessmentto establish whether all or parts of a coastal area contains outstanding natural character is undertaken onlywhen all of the attributes, when assessed at an adequate scale andusing adequate data, is assessed as containing‘high’ or ‘very high’ levels of natural character.Of the attributes within a coastal area having ‘high’ or ‘very high’ levels of natural character to be considered ‘outstanding’,they must: ‘exhibit a combination of natural elements, patterns and processes that are exceptional intheir extent, intactness, integrity and lack of built structures (the ‘clutter’ factor ) and other modifications comparedto other areas in the Hurunui District.DRAFTAreas of Outstanding <strong>Natural</strong> Character have been mapped and identified by their extent.The isolated Waiau River Mouth (above) is separated from inland basins by a range of coastal hills in privateownership.Hurunui District | <strong>2013</strong>

28Hurunui Coastal AreasBased on the methodology in outlined in Section C of this report 12 coastal areas with homogenous landscape characterwere identified. The following section provides a description and assessment of the natural character values of each area.Coastal Area 1 : ClaverleyThe northernmost coastal area of the district is broadly defined by the Okarahia Stream, which enters the seaimmediately south of the Haumuri Bluffs, which are part of the Kaikoura District. The coastline is accessible inparts, via the Claverley Road, which terminates at Claverley. The main north railway line extends close to the coastalong this stretch of the district. There are several watercourses that drain the inland hills in this rural coastal area,including Claverley Creek and Waitotaranui where deep incised, bush-clad gullies divide the grassy paddocks.Coastal ContextThe hinterland of this coastal area contains the eastern part of the undulating Hundalee Hills, which are dissectedby SH1. Generally the land cover of the foothills is modified by pastoral use, with some remnants of nativevegetation in the gullies and stream, such as the kanuka and broadleaf vegetation in the Okarahia Stream and OldClaverley Creek catchments.° N0 0. 5 1.5 KmHurunui District | <strong>2013</strong>1:50,000

32Coastal Area 2 : Conway FlatsThe coast between the settlement at Claverley to the north and Sawpit Creek to the south, features the ConwayRiver mouth and lagoon. This area south of the impressive Haumuri Bluffs and headland of Spy Glass Point comprisesmodified lowland farms backing high-energy gravel beaches. This coastal area is predominantly intensivelyfarmed flats which contrast with the natural patterns around the centrally located Conway River mouth.Coastal ContextThe Conway Flats are intensively farmed with a patchwork of improved pastures. The backdrop of the Conway Flatsis dominated by the Hundalee Hills, where the Conway River emerges between Mt Guardian to the north and SkullPeak to the south. The Derek and Limestone Stream catchments on the northern slopes contain large areas of regeneratingscrub, such as kanuka, while the southern hills are generally covered in extensive pastures. Remnants ofnative vegetation can be found in the gullies of the incised Waitotaranui Creek catchment and above the ConwayRiver.

The lagoon at the ConwayRiver mouth is notable for its unusual salt marshcommunity, including a native sedge and raupo, whichfringes parts of the landward margins of the lagoon.A small area of conservation land is designated alongthe Conway River mouth with the remainder of thecoastal plains in pastoral farming uses. The trees liningthe lower Conway and river mouth are predominantlyexotic, in particular willows and wattles form densefloodplain forests along some sections of the banks.Land Cover and Land UseThe gravel beach and Conway River mouth/ lagoon arefree of human modification and structures, howeverthe coastal plains are dominated by agricultural landuses apart from the native vegetation occurring aroundthe river mouth. The majority of the coastal plainscontain paddocks, separated by coniferous shelterbelts.Settlement in the coastal environment is very limited.There are few individual houses near the northern andsouthern extent of the area in proximity to the coast.SECTION DAlluvial flats surround the lower Conway, backed by the Hundalee foothills and raised marine terraces to the northand south.Hurunui District | <strong>2013</strong>
36Coastal Area 3 : Conway TerracesSouth of the Conway River a series of raised marine terraces extends to the mouth of the Waiau River. Theseterraces are dissected by numerous ephemeral streams which drain the steeply rising hill slopes of the HawkswoodRange to the west. The native vegetation contained in these deeply incised gullies is notable and contrasts withthe improved paddocks on the flat elevated terraces. Steep sea cliffs and a narrow gravel beach form the ruggedcoastline.Coastal ContextThe Hawkswood Range, which rises to almost 700 metres in height, separates the Conway coast from the inlandParnassus Basin. Various terrace levels can be distinguished on the eastern slopes of the range between HaumuriBluffs in the north and Waiau River in the south. While the terraces are flat or gently sloping, the hill slopes riserelatively steeply to the west.

92Appendix 2 Definition of Criteria for ONL IdentificationThe criteria for identification of Outstanding <strong>Natural</strong> <strong>Landscapes</strong> applied in the Hurunui Landscape Study (1995, LucasAssociates) were defined as follows:1. NATURAL SCIENCE<strong>Natural</strong> features and landscapes of at least district importance for reasons of the rarity or representativeness of theirparticular landform and landcover. A natural feature may be a landscape feature or an element/component of thelandscape. Under S.6(b) geology and soils are elements of particular focus, as flora and fauna values are also consideredelsewhere in the Act.2. LEGIBILITYThe landscape (or natural feature) of district significance should clearly express past natural and/or cultural processes.Some may have strong historical connotations and a distinctive sense of place.3. TRANSIENTThe natural feature or landscape of district significance providing predictable or regular experience of dimensions ofnature other than landform or landcover e.g. concentrations of wildlife.4. AESTHETIC<strong>Landscapes</strong> (and natural features where applicable) that are of high aesthetic value determined on how memorable theyare, on their naturalness, on their composition (coherence) and on other important aesthetic factors.5. SHARED AND RECOGNISEDThere should be a substantial measure of agreement between professional and public opinion as to the value of naturalfeatures and landscapes, for example as reflected through writings and paintings or through favourite locations to cite orvisit. The presence of existing protected sites is also likely to reflect shared and recognised values.6. TANGATA WHENUADRAFTThe natural feature or landscape identified as having particular district importance to tangata whenua.Appendix 3 Geopreservation Sites Waipara Gorge ONF/LWaipara River Cretaceous-Paleocene Sequence- CanterburySIGNIFICANCE: One of the most complete and well exposed K-T sequences in New Zealand.

The first Land Cover Database (LCDB1) was completedin 2000 using SPOT satellite imagery acquired over the summer of 1996/97. LCDB2 was released in July 2004 and usedLandsat 7 ETM+ satellite imagery acquired over the summer of 2001/02. The new release reports land cover/land usechange for the five-year period between each acquisition of satellite imagery.The Landsat 7 imagery used has been pan-sharpened to 15m spatial resolution then orthorectified using groundcontrol point pairs from ortho-photography to a target r.m.s. (root mean square) positional mapping error of 20m. In areaswith good ground control the Landsat imagery is correct to within 1 pixel. In areas with poor control (typically mountainousterrain) the imagery may have a positional error of two or more pixels.Polygon boundaries have been created using both, automated and manual digitising techniques. Manual digitisingwas undertaken at a display screen resolution of 1:15 000. Cartographically this results in a mixture of “rasterised” andsmooth polygons. This has been retained in the database to remind users of the spatial resolution of the imagery used. Theraster effect becomes noticeable at 1:25 000 and users are advised to use the data at 1:25 000 or smaller scales to avoidvisually having to confront this effect. Given the spatial resolution, ortho-rectification error and scale of manual digitisingof LCDB2, it is good practice to use LCDB2 at a scale of 1:25 000 or smaller, (i.e. 1:50 000).2 Critical sites integrate the conservation values of threatened and representative species and habitats in terrestrial,freshwater and marine ecosystems. They may have a variety of features contributing to their status such as the presenceof representative or threatened species or habitats, connections between high value sites, or that they are a large area ofrelatively intact habitat.Hurunui District | <strong>2013</strong>
