CONTEXTAuckland is New Zealand’s largest city, commercial centre and home to a third of the population. It is the dominant commercial focus of New Zealand with its large domestic market, infrastructure, port and airport, commercial expertise and diverse manufacturing and industrial base. It is also one of the fastest growing cities in Australasia. Alongside this growth is a growing demand for business, housing and a consequent increase in our use of infrastructure and natural resources. Growth and development provide new opportunities and make Auckland an exciting and vibrant place to live. However, if not managed well, growth can affect the health and amenity of our natural and physical environment that we value highly.

Home to just over 6000, Karaka is traditionally a rural district, with only around 2000 homes that inhabit the area today. A young population with a median age of 38, Karaka is best known for its production of thoroughbred horses and sales that attract buyers from all over the world. Currently the area is being used as farmland, this is due to its highly fertile soil, flat open spaces and ecologically rich environment producing high quality stock and exports. Before the forming of the Auckland super city, Karaka was part of the Franklin district about 30mins from central Auckland. Surrounded by the Manukau harbor and boarded by Weymouth to the north, Karaka has the potential for a substantial urban development.

With the urban sprawling pattern that Auckland is going through, Karaka is in an optimal place to develop. Taking inspiration from other rural developments like Flatbush and the Albany transport hub, Karaka can be transformed into an example urban development, showcasing innovation and ecological planning. Planning a site that is at its forefront of modern thinking and accessible to all forms of public transport, creating a community that can set a standard for Auckland’s progression.

CHOSEN SITE FOR DEVELOPMENT

SITE CONTEXT

SCALE: 1:40000

An increase of 1 million people is said to sprawl into Auckland over the next 30 years, which will require a total of 400,000 dwellings. The key focus is not solely on where we pinpoint our dwelling allocations, but also on integrating the existing qualities of the landscape with the developed zone to create a co-existing system.

With consideration to the landscape character, it is important to use varied housing densities in order to control the urban impact within Karaka. For our development proposals, we have chose a section of Karaka West that incorporates the different intensities of housing (high, medium, low), as well as the integration of ecological systems and permeable open spaces. The 60hA chosen site acts as a link between the industrial core and the proposed connection to Weymouth, adapting the main flow of traffic through the Karaka as an urban subdivision.

KEY

Slope > 15°

SLOPE

SCALE: 1:5000

The slopes greater than 15° have been retired. These areas will not be a logical place to carry out urban development. However, from looking at the retired slope areas we can see that the focused extent is mainly flat surrounding Urquhart road, allowing for development across a majority of the area based on the GIS data collected. These slopes could however accommodate a number of vegetation species and be the basis for a re-vegetation scheme.

RIVERS AND STREAMS

KEY

River

SCALE: 1:5000

Within the focused extent only 2 streams intersect the site towards the edge. It is ideally logical to retire around these existing spaces as vegetation that is used to secure the steep banks. It is important to filter our systems naturally through vegetation so that Karaka as a sub-division will continue to promote the ethical water management.

WATER FLOW

SCALE: 1:5000

The existing flow direction pattern shows run-off being discharged towards the east and west flanks of Urquhart Road. There is a greater impact of water run-off towards Northeast, East, Southwest and South because of the current topography of chosen site. Flow accumulation shows the collective zones as to where run-off is being stored in relation to the aspects of flow direction. It would be a logical idea to retire most of the surrounding land nearby the flow accumu-lation zones and potentially re-vegetate surroundings.

WATERSHED AND BASIN

SCALE: 1:5000

A drainage basin is an extent or an area of land where surface water from rain and melting snow or ice converges to a single point, usually the exit of the basin, where the waters join another water-body, such as a river, lake, reservoir, estuary, wetland, sea, or ocean. There are 4 main drainage basins that exist within the focused extent. The edges of these basins construct a diagrammatic layout of the water shed. Run-off is not contained within the site and is dispersed towards the east and west.

According to the aspect analysis of the chosen site, South, Southwest, West (247.5-292.5), Northwest (292.5-337.5) and North (337.5-360) are the most dominant throughout. Pockets of Flat, North (0-22.5), Northeast and East are spread adjacent to the rest of the classes. Usually north-facing houses get sun most of the day mainly at the front compared to south-facing houses. From an ecological perspective, north-facing houses are more energy efficient as well.

VIEWSHED

SCALE: 1:5000

The views depicted from the GIS data were from a 2 meter level which is an approximate view from a human per-spective, and an optimum height of 10 meters from the peak of high density dwellings. It is clearly established most of Karaka can be viewed from a 10 meter height covering patches of landform. However from the 2 meter height mostly landform within the same horizon level or lower can be viewed.

A 10 and 2 meter height view from the Medium density shows areas which can be viewed within the focused extent. The 2 meter height view is much restricted due to existing raised topography surrounding the marker, which is situated over a 23 meter high landform. Where as the 10 meter view within medium density also has a minimal restricted view.

KEY

Development of the location resides of high, medium and low densities, which integrate proposals of hydrology and vegetation to a sustainable design outcome. The high-density comprises of two 110 square meters housing approximately for apart-ment style living within a 630 square meter lots. The high-density housing is developed on an optimum scale of 3 stories apartment style living to house a high count of people. Between the high and medium-density zones are a number of retail for the residents to utilize. This was the ideal location to accommodate a small scaled retail due to the main core, located further down south consisting of large scaled retail and amenities to serve the residents of Karaka. Medium density contains 180 square meters of housing per 400 square meter lots. In the middle of medium and low-density is a potential for a development of schooling. This is located facing Urquhart road. The medium and high-density follow the Traditional Subdivision Pattern model and carry out its fundamental characteristics. Furthermore low density holds 330 square meter houses within approximately 800 square meter lots. The purpose of creating a cluster development proposal is to accommodate the increasing population of Auckland, following the core objective of the Unitary Plan.

Each lot has been integrated with sufficient private owned parking space, with additional section of street parking for visitors. The street parking is roughly 2.3 metres by 5 metres per parking.

Note: The exiting building footprints established on the image are not the final amount. The image is used to show a variation between high, medium and low-densities.

CIRCULATION: PEDESTRIAN + CYCLE + ROADS

FOOTPATHS

ROADS

The footpaths are relatively between 1-2 meters wide benefiting sufficient space for pedestrians. Footpaths also accommodate cycle ways and create a circulation within the community due to overlapping of footpaths. Further use of cycle means can also be carry forward to road space bearing in mind not to hinder the traffic.

During the development phase of constructing a new road layout, was based on the previous analysis of hydrology flow, slope, aspect and watershedcs and particularly contours. The main roads were designed at an approximate width of 16 meters excluding footpaths, allowing an adequate space for street parking. The roads are double lane to accommodate heavy traffic flow especially through main arterial roads (Urquhart Rd), due to a wider connection through Weymouth via a causeway link to Karaka.

HYDROLOGY

Hydrology systems

KEY

Hydrology within the focused extent is a key element, which shapes the land and its future development. Based on the analysis of the current condition of flow accumulation, flow direction and watersheds; the new proposal of hydrology systems have been placed in relation to the analysis to carry out functions of a clean water management system, to capture storm water runoff, to mitigate erosion and increase biodiversity within surrounding hydrology patches. This specific design allows a further approach towards preserving agriculture and its topography in relation to retaining clean hydrology. Pockets of hydrology systems have been incorporated within the design for its various purposes to achieve a better sustainable outcome.

The vegetation patches run throughout the site to increase biodiversity amongst the different densities and create a more liveable atmosphere. The big ecosystem patches follow the perimeter of the site retiring the surrounding land due to 2 streams which intersect the site. The inner core of the large native forest planting culminates a minor wetland and riparian planting zone to filter storm water runoff into the proposed hydrology systems and increase irrigation within the area. Pockets of vegetation have been integrated within the land for amenities and benefit various purposes. The open space can be used as shared space for a range of activities.

Wetland/Riparian planting:- Apodasmia similis (Oioi)- Baumea articulate (jointed twig rush)- Carex germinate (cutty grass)- Elocharis acuta (spike rush)- Phormium tenax (Harekeke flax)- Caprosma robusta (karamu)

The second stage development process of Karaka consists of an ethical approach towards three key impressions such as LIUDD (Low Impact Urban Design), Traditional Subdivision Pattern model and preserving agriculture in relation to the hydrology connectivity of the chosen site.

The 60 Ha site establishes a relatively flat landform as per the analysis. The chosen site is a land for potential urban development to house thousands. The design proposal is showcases the different density zones within the site accommodating apartment style living housing (within high-density) to large plot sizes (within low-density). The proposal aims to integrate ecology within the community to increase biodiversity and enhance a sustainable hydrology system in relation to it. The new road and footpath structure accommodate sufficient area for peak traffic flow, where as the footpaths are designed for pedestrians and cycle ways to generate circulation within each density zones. The sustainable urban sprawl within Karaka is the outcome of the Unitary Plan’s objective.

SHAYNE’S PROPOSAL

19


The focused extent of development displays high, medium and low density living conditions. As proposed in the growth strategy, the 200m2, 3 level apartment style building footprints contained within a 600m2 lot-size accommodates a higher quantity of people as well as parking spaces, shared accessibility and private gardens. The proximity to high quality retail within the core located south of this area creates no demand for dense retail within the zone. With minimal hospitality services (e.g. cafes), these amenities contribute to a beneficial living condition. The layout of these high density building footprints create an optimum space where land can be productively used.

At 250m2 housing, medium density dwellings sit within a 600m2 where 2 houses share a driveway and but still consist of their own private garden and living space. The Traditional Subdivision Pattern has influences the design of this density zone and has created the layout structure of housing and spaces. Private parking has been integrated within each lot size along with public parking spaces on streets. The idea is to reduce the number of roads introduced on site, and create a more permeable urban space in terms of hydrology. Within medium density, the concept of creating a livable space is introduced with accessibility to schools and public open spaces. The allocation of small retail zones contributes towards the list of the community’s amenities and aids the sustainability of urban lifestyle within the area.

In the low density area, dwellings have been placed within large 800m2 lots. The large green spaces within the lots alongside the patches of housing contribute towards a relaxed lifestyle away from the intensities created by the urban lifestyle. Private parking has been integrated within the lot size for each dwelling. Public street parking is available, although the low density environment would expect minimal long term vehicle interaction. In terms of impact on the land, the Low Impact Urban Design and Development model drives the concept of this zone and ensures a positive living environment, not only for humans but also for vegetation and fauna.

RoadsThe proposal of the bridge connection to Weymouth createvs a new form of traffic flow through Karaka West. Urquhart Road accommodates the main flow of traffic flow through the specified site with links to other roads leading to several areas of the residential subdivision as well as the wider context of the Karaka West Coast, Karaka North, Weymouth and Karaka Lakes. With single lanes roads, wider roads provide on street parking, with spaces for vegetated medians. These wider roads also allow for cycle ways to be implemented in order to avoid negative interactions. Analysis of water flow direction, water flow accumulation, slope, aspect and watershed influence the movement of vehicles on site and create a web of connections within the landscape.

Cycle + PedestriansSufficient space is allocated for footpaths adjacent to roads that allow pedestrians to access several areas of the site. These pathways are roughly 1.5 – 2m wide, which provide a safe space away from traffic for pedestrians to travel. The roadside pathways create links through several other pathways through parks and reserves where experiential journeys create optimum spaces for people to enjoy the natural beauty of the landscape. These pathways are also accessible by cyclists. Due to many connecting roads, a circulation through the community is creating within the landscape for pedestrians and cyclists.

HYDROLOGY

The GIS analysis of hydrology patterns on site creates an understanding of water on site and the areas it flows to. Information about the landform implicates the allocation of water management systems on site. The concept is to allow the existing topography to direct water off the roads and slow the process of water run off. Rain gardens are allocated to allow rainwater runoff from impervious urban surfaces to be absorbed into the ground. These rain gardens will dramatically cut down on the amount of pollution reaching creeks and streams. Native plants within these gardens are ideal as they do not require fertilizer and are tolerant of the climate, soil and water conditions while also attracting local wildlife such as native birds. Root systems will enhance infiltration and improve soil permeability and provide moisture redistribution. Through the process of transpiration, these rain gardens will also return water vapor to the atmosphere. It is important to implement ethical ways to manage water within the proposed urban setting.

VEGETATION AND OPEN SPACESWith 2 streams intersecting the sites boundary, these areas have become the wetland/riparian zones within the site. The wetland/riparian zones bring a high level of biodiversity to the site with a variety of plant species, as well as fauna species due to is secure habitat qualities. These riparian zones also work to reduce pollutant entering the Manukau Harbour, and increase the stability of the steep banks. The concept of this riparian area is to implicate a self-sustaining planting system that requires minimal human management due to the application of ecological understanding of species distribution. The ecosystems qualities bring many interrelationships within the site that positively impacts the land.

Within the densities a series of parks and reserves contribute towards the high percentage of permeable surfaces within the area as well as create spaces for recreation and leisure. Revegetation of native species within these areas will increase the diversity within the whole site and create a positive environment for living.

MASTER PLAN

The increasing population of Auckland creates a demand for a growth strategy and has driven the concept of allocated densities within Karaka. As stewards of the land, preserving and managing ecological significance is a key concept of this proposal. While creating spaces for recreation and leisure, the several parks and reserves on site contribute towards a high percentage of permeable surfaces within the urban context. While the traditional subdivision layout creates the basic layout of medium density housing, a high level of ecology is integrating into the area. The increase in population drives the development of housing, but it is important to remember that we need to create places that are livable and most importantly sustainable. Large areas, such as schools, contribute to the high percentage of permeable surfaces in the area, as well as providing for the community. A network of cycle ways and pedestrian focused paths produce a flow of movement through the site, exploring the different layers of housing densities while creating an ecological journey through diverse species of vegetation. The combined zones create a livable space where people of all ages can access and benefit within the site. The idea of an ecologically sensitive urban development proposal is to continue our urban culture, knowing that we can live smarter and more efficiently without dramatically impacting the land. With specific consideration to ecology of hydrology and natural systems, the layout of this 60hA site creates a healthy living condition for the community and sets an ethical model to base the development of Karaka on.

VAUGHAN’S PROPOSAL

Amenities have been provided to accommodate the inhabitants and public space set aside to provide all functions needed of a growing community. The highway that runs through the site enables the ability to connect this community easier to the rest of Auckland, bringing in people and foot traffic into the area. In my opinion, Karaka has the potential to become an example of modern Landscape Architecture thinking, focusing on the protection and enhancement of ecosystems even with the introduction of urban development.

VEGETATION, OPEN SPACES AND DENSITY ZONES

The open spaces can also be reffered to as shared spaces within each density zone. The revegetation which can be established at the perimeter of the site are mainly retired land due to existing hydrology restraints intersecting the 60 Ha site. A storm water retention pond has been placed further south of the site to retain runoff from mainly surrounding streets. The open spaces adjacent to the large ecosystem patches are utilized specially by residents of Karaka for recreational purposes and other activites.

Densities and cadastral’s were calculated in a dwelling per hectare ratio of standard densities. This with the inclusion of the subdivision models gave me the ability to keep to a natural looking area that has the ability to accommodate the increase of population whilst helping to aid the ecology of the area.

Low DensityMy low-density sections are at a plot size of 1452 sq/m. This accommodates 12 dwellings per hectare for a population of around 40 people.

Medium DensityMedium density sections are your typical suburban suburb. These plot sizes are at 363 sq/m, this density can accommodate 25 dwellings per hectare with a population of around 82 people. As this is your standard density, I have allocated medium density with the most plot sizes. Allowing to maintain a low impact model.

High DensityFor high density I took examples from new developments scattered over Auckland. I tried to centralize high-density development around areas with a slope to allow for grey water to be filtered. High density will have the most impervious surfaces so I located it in an area where water runoff can be controlled and filtered before returning into the estuary. This is why I have put my storm water retention pond in the center of this development. High density is on a plot size of 528 sq/m with 40 dwellings per hectare. As a group we decided to make high density as 3 story apartment buildings with 1 dwelling per floor. By setting our high density at a restricted height, we can control the amount of dwellings built and population, which will be around 132 people per hectare.

SCALE: 1:5000

27

MASTER PLAN

My plan is the combination of 2 different subdivision strategies. First is a low impact subdivision, which focuses on leaving open space and limiting your amount of impervious surfaces. The second is a conservation sub division, which focuses on buffering ecological systems and bush and improving the quality of those ecosystems through sustainable design. I tried to stick true to this by allocating all my bush areas first; I worked backwards focusing on ecological areas to protect and which land best-suited development. I can use the slope to control storm water runoff into a retention pond. This pond will have multiple filtration plantings in place to help improve water quality before the water is released back into the estuary.

I also allocated a sizeable amount of land to be turned into reserves or open green space. I feel this is important for this sub division, as I want to protect the character of the site. For this to be done, bush land and open parks need to remain, instead of concreting the area. My roads were all designed around the contours of the site as well as the allocated bush areas, this was to keep a more natural look through curves instead of having multiple perpendicular roads.

LOGAN’S PROPOSAL

29


High density lots (40 dw/HA) feature 3 story apartment style buildings. The space around the buildings have not been designed to supply large back yard areas because the arrangement of these lots allow them to always face natural amenities (the open spaces are the buildings back yards). The surrounding vegetation breaks the high density in to zones to steer away from building domination around all areas of Karaka to create a unique style of living. The largest intensity of high density living is along the main Rd (Urquhart Rd) and diffuses breaking up in to smaller zones featuring colder sack arrangements and single lot depth.

Medium density living features an arrangement of roads and lots that supply frequent amenities and open spaces. Ally ways of green space provide for cycling short cuts and weekly market spaces. Most lots will back onto public space allowing for a range of prices for houses. The arrangement of lots and open space direct the water run off towards the roads and down a gentle slope towards the vegetation before it enters the ocean. Most surfaces in medium density zones are penetrable surfaces to encourage a rural feel and help with drainage.

Low density living is at 12dw/HA and allows for larger building foot prints and a pricier style of living. These lots are on the outskirts but still keep central to the main road. All roads in these zones are gravel surfaces that support swales to direct water flow. Living in low density features a lot of green space and most of the sections back on vegetation. The lots in these zones decrease in intensity as they move away from the road and turn in to single lane roads/driveways.

KEY

Footpaths

Cycle Ways

My site features one main Rd (Urquhart) that will be the core route for the bulk of the transport that will be used in Karaka. All other roads are residential streets that support housing on both sides with 2-3 lots deep (maximum). The residential streets all follow ridgelines and flat spots in the site to allow for minimal water flow obstruction. Most roads feature footpaths on both sides to encourage the walking factor on this relatively flat site. A main cycle route is also provided that weaves Off roads and into public spaces, providing the shortest route and also safe as it is not running parallel to roads.

HYDROLOGY

KEY

Hydrology

The idea behind the hydrology on my site is that it is as free flowing as possible. Strategically placed roads along ridgelines allow for limited water flow obstruction there for minimal flooding. I have placed treatment ponds at the base of each sub catchment and one by the main Rd were there is consistent water accumulation (according to GIS data). The idea of the mixed planting with treatment ponds is for the vegetation to act as a belt at the start of the ridge lines so that all water run off passes through some kind of vegetation and into the ponds allowing for maximum filtration before entering the Manukau harbor. The lay of the land is quite flat featuring shallow rolling hills so to allow for direction in the flow of water, I have allowed for swales to be on the sides of roads and parallel to main cycle paths. Everything flows down hill and the arrangement of building footprints and roads supports that.

KEY

I have re-vegetated along all the steep slopes of my site that are mostly located on the fringe of my border. The planting of this follows a successional pattern (planting starts small then progresses into larger species and finally into bush before meeting the ocean. The planting allows for maximum filtration of water runoff and fingering strands provide for natural like zones within the living environment. The distance between major planting is close enough to support the idea of metapopulation and provide an ideal living environment for bird life and other wild life. The planting will ensure for a positive ecological footprint that balances out the housing footprint and creates a balanced living environment.

KEY

All roads and lots have been placed strategically to limit the amount of water build up and erosion. All roads follow along the ridgelines of the sub catchments in this 60HA zone to allow for storm water and rain water to flow naturally with minimal disturbances. Vegetation increases as it gets closer to valleys and significant dips in the land to create a gate for water run off. These gates filter run off water before they enter the ocean to promote a cleaner ecological living environment.

To promote a rural living atmosphere, I have allowed for areas (within medium densities) to support local produce and horticultural services. An increase in vegetation breaks up the intensity of housing and creates natural amenities and limited movement of land form will keep the rolling hill factor of Karaka.
