Volcanic Viewshafts Management Framework Proposed Methodology Applied to Seven Case Studies JUNE 2015 PROPOSED AUCKLAND UNITARY PLAN HEARING 020 - VOLCANIC VIEWSHAFTS VOLCANIC VIEWSHAFTS MANAGEMENT FRAMEWORK PROPOSED METHODOLOGY APPLIED TO SEVEN CASE STUDIES JUNE 2015 PROPOSED AUCKLAND UNITARY PLAN HEARING 020 - VOLCANIC VIEWSHAFTS VOLCANIC VIEWSHAFTS MANAGEMENT FRAMEWORK PART A: IDENTIFICATION The purpose of this stage is to identify the range of potential viewshafts across Auckland and qualitatively capture information about them. The identification process is not concerned with ranking one viewshaft against another, or assessing the potential impact of imposing the viewshaft. It is envisaged that the process of identification is well documented in order to provide clarity for later stages. The methodology for identification of viewshafts to be potentially protected involves consideration of the following factors: 1. Significance of the Individual Cone: • Physical stature: elevation, scale, profile, dominance, legibility • Intactness: topography, form • Character: vegetation cover, land use cover / elements • Social Value & Status: reserves / art / literature / tourism • Cultural / Tangata Whenua Values: pa sites / remnants / commemorative elements. 2. Significance of Origin Point: • Type of View: Transport Corridors (e.g. commuter and main trunk rail routes), Strategic Road Routes (nationally important) / Regional Arterial Road Routes (regionally important), parks & reserves / open spaces / beaches / promenades / sports fields / walkways & cycleways / commercial centres / community centres • Identification and Nature of the Viewing Audience: e.g. static/transient, drivers and passengers of vehicles, pedestrians, passive users (e.g. park), regional community, tourists, reason for being at origin, frequency of use, time spent • Nature of the View: temporality, linear or point or cumulative points • Distractions: Foreground activity, other important views 3. View Quality: • Memorability • Shared Recognition / Recall • Orientation of View: to viewer at Origin Point – focus of view or peripheral • Proximity to Cone: Surrounding context • Clarity of Expression: Demarcation of Cone Relative To Surrounding Terrain / Development (including visual ‘breathing space’ around the cone) • Uniqueness: Visual Catchment Relative To Other Origin Points, context/composition • Contribution to City: Significance, Identity, ‘Gateway’ Values (introduction to Isthmus cone field), Wayfinding, landmark values 4. Cumulative Value: • Visual connection with other volcanic cones (of similar or higher significance) • Visual Connection with other volcanic features of the Auckland Isthmus • Sequential connection: Between viewshafts. 4 Auckland Unitary Plan - Volcanic Viewshaft Management Framework - PART A POTENTIAL VOLCANIC VIEWSHAFT Volcanic Cone Te Ahi ka roa a Raka / Mount Albert / Owairaka Origin Point 340 Mount Albert Road, Wesley (Existing viewshaft: A08) IdentificationPart A Criteria DESCRIPTION EVALUATION OF VALUES OF VALUES 1. Significance of the Individual Cone Physical stature • As the western-most volcanic cone on the Auckland Volcanic Field Mt Albert provides a clear orientation about the western part of the Auckland Isthmus. • Has a height of 135m (ASL) • Comprised of two scoria cones that have been quarried. • Has a wider east/west profile due to the number of cones. Intactness Overall, the base of the maunga is largely intact the top has been extensively modified from quarrying (the top 15m of the cone was removed) and the addition of water reservoirs. Character • Has a modified character. The top of the cone has been levelled (as a result of quarrying and then water reservoirs) and so the maunga has an unnaturally flat grassed top which is now used as sports fields. • Two smaller, older reservoirs were built at the main entrance of the domain. • Vegetation predominantly includes grass and established trees, particularly in the excavated crater. • Dwellings have been built around the base of the cone. Social Value & • Mount Albert is a landmark for Auckland. Status • Quarrying generated decades of persistent (and eventually successful) public protest to stop the quarrying. • Currently used as a recreational reserve and appreciated for its amenity. Reference: Boffa Miskell, 2015 Cultural / Tangata Former pa site and some terracing still visible. Whenua Values 2. Significance of Origin Point Type of View The view is transient, urban view located on a public road (the origin point is located on an arterial road). Identification and As an arterial road, the potential viewshafts can be Nature of the experienced by a broad number of drivers and pedestrians Viewing Audience heading in a westerly direction along Mount Albert Road. Nature of the The origin point is defined by a singular point (but the maunga View can be recognised and appreciated after this point is passed). Distractions • Road and other vehicles. • Pedestrians. • Built form in the foreground and mid ground. 3. View Quality Memorability The limited view of the overall cone makes it difficult to recognise as an important maunga and therefore difficult to appreciate. Distracting elements in the foreground and mid- ground further reduce memorability. Shared For similar reasons above, from this origin point there is not a Recognition considerable shared recognition or recall of the maunga. /Recall Orientation of The maunga is located in direct alignment with the road View corridor. Proximity to Cone The origin point is 2.6km from the maunga. Clarity of Foreground and mid ground elements (comprised of Expression vegetation, built form and road reserve elements such as street lamps) cramp the view of the maunga and blur the distinction of cone form with its surrounding context. Uniqueness This potential viewshaft is not especially unique. Other better quality views pf Owairaka / Mount Albert can be recognised and appreciated from other points along Mount Albert Road. Contribution to The connection between the road name of Mount Albert Road City and the cone itself provide a help orientation/legibility element to the viewshaft but overall, the view is not particularly strong. 4. Cumulative Value Does this potential viewshaft have a visual connection with other: Volcanic cones No. Volcanic features No. Natural features No. Other features No. Sequential Only with other views of Owairaka / Mount Albert connections PRELIMINARY CASE STUDY 5 Auckland Unitary Plan - Volcanic Viewshaft Management Framework - PART A POTENTIAL VOLCANIC VIEWSHAFT Volcanic Cone Maungawhau / Mount Eden Origin Point South-bound lane, Onewa Road Off/On Ramp, SH1 (Existing viewshaft: E10) IdentificationPart A Criteria DESCRIPTION EVALUATION OF VALUES OF VALUES 1. Significance of the Individual Cone Physical stature • The trig point at the top of Maungawhau is the highest point on the Auckland isthmus (196m ASL). • Comprised of multiple scoria cones surrounded by lava fields. • Has a longer east/west profile. • Forms a dominant part of the central Auckland skyline Intactness • The cone has been considerably modified. Pre-European times, the tops and sides of Maungawhau scoria cones were extensively modified to create a pa. Many pits were made for crop storage. • Maungawhau has also been subject to quarrying on the southern (now Eden Gardens) and northern slopes (now Tahake reserve). • The main crater of the southern cone is relatively intact and such a deep and perfectly shaped crater is considered by many as a rare example in Auckland. Character • Has a modified character. • Mixed vegetation: The upper cone is grassed. The mid to lower flanks are comprised of a mixture of vegetation including mature trees. Areas of native bush regeneration exist along the western flanks. • Roads and walking routes. Car park areas at various levels along the procession up to the cone but the main car park is on the top, southern rim of the younger scoria cone. • Dwellings have been built around the lower flanks of the cone. Social Value & • Auckland’s most recognisable cone along with Maungakiekie / Status One Tree Hill and Rangitoto. • Friends of Maungawhau community group Reference: Boffa Miskell, 2015 • Represented in many artwork, literature and music. • Currently used as a recreational reserve and appreciated for its amenity. Cultural / Tangata Former Pa site and features kumara pits Whenua Values 2. Significance of Origin Point Type of View • 800m long, sectional origin point (similar to 30 seconds of viewing) • Origin point is located on the Northern Motorway (100km p/h zone) and is experienced by moving vehicles only. Identification and As a national motorway, the viewshaft can be experienced by a vast Nature of the number of drivers and pedestrians heading in a south along SH1 – Viewing Audience this includes people passing through Auckland. Nature of the Linear viewshaft, off –centre to the left (south) View Distractions • As a driver, the road and other vehicles are the main distraction particularly as the view is off-centre. • Built form along the motorway (such as the Onewa on-ramp/off- ram, signage and lighting) and the built form of the City Centre. 3. View Quality Memorability The view is considered to be memorable. The contrast of the natural landscape of Maungawhau /Mount Eden against the built form of the City Centre and Waitemata Harbour creates a distinct and memorable impression of Auckland. Shared The number of users of the northern motorway and the ease of view Recognition toward the cone would resonate with a wide viewing audience. /Recall Orientation of The maunga is off-centre but easy to view

This is reflected in the UNESCO IGCP Project (# 692. Geoheritage for Geohazard Resilience) that continues to successfully develop global awareness of the multifaced aspects of geoheritage research. Geohazards form a great variety of natural phenomena that should be properly identified, and their importance communicated to all levels of society. This is especially the case in urban areas such as Auckland. The largest socio-economic urban center in New Zealand, Auckland faces potential volcanic hazards as it sits on an active Quaternary monogenetic volcanic field. Individual volcanic geosites of young eruptive products are considered to form the foundation of community Citation: Németh, K.; Gravis, I.; outreach demonstrating causes and consequences of volcanism associated volcanism.

The isthmus not only offered rich volcanic soils, many waterways and inlets, but also a strategic location for trade. Auckland was centered on interconnecting trade routes between the Bay of Plenty, Coromandel, Waikato and Northland.*https://teara.govt.nz/en/tamaki-tribes/page-1 Around 1250 A.D., voyagers on canoes from East Polynesia became the earliest settlers of New Zealand. Among the many canoes, the Tainui canoe pulled ashore at Waitematā Harbour (Auckland Harbour) and its descendants put down roots in the Auckland Isthmus.*https://teara.govt.nz/en/tamaki-tribes/page-1 And by the 19th century, much of the Hauraki Gulf, including the eastern coast of Auckland, was inhabited by the descendant tribes of Marutūahu of the Taninui canoe.
