karaka

_ context

Karaka is a small rural area of Auckland, New Zealand. Formally part of Franklin District, under the authority of the Franklin District Council it is now part of Auckland City. It is primarily a rural town associated with horse studs as well as dairy and sheep farming. In recent times, some of the pastoral land has been subdivided into expensive residential plots. Traditionally the economy of Karaka was dominated by agriculture with Brink’s NZ chicken originating in Karaka. However in recent times with the move to lifestyle blocks the majority of residents commute to Auckland for employment. With the NZ Bloodstock Karaka Sales Complex located in Karaka, thoroughbred studs have become increasingly important to the local economy with Westbury Stud and Haunui Farm both located in Karaka. Three public primary schools are located in karaka, Karaka School, Te Hihi School and recently opened Hingaia Peninsula. As well as one private coeducational secondary school, Strathallan. Public secondary education is provided in the nearby towns of Papakura and Pukekohe. Karaka is the location of the thoroughbred yearling sales at NZ Bloodstock Karaka Sales Complex. The Karaka Sports Park provides a local sports ground as well as bar and kitchen facilities; there are also a few small restaurants in the area. The Pukekohe Golf Club is located within the Karaka area bordering Pukekohe.


zoning

_ project one

The constraints and other issues explored by the contextual and land suitability analysis can be approached as positive factors rather than negative constraints by considering how the areas which should not be developed could be otherwise utilised to achieve ecological goals and create high quality, resilient living in Karaka. For example: Areas where there is a high concentration of south facing aspects and/or slopes over 15 degrees are to be retired from development and re-vegetated. River banks and areas with complex catchments are to be extensively ecologically buffered to a minimum of 50m on either side of the existing water pathways. This will help to reduce land erosion and allow greater room for any future changes in water flow direction or fluctuations in river levels. All coastal areas, 100m from the high tide line are also to be retired from the development. This will help protect the development from the threat of sea level rise and provide full public access to the coastline. Some larger areas close to the harbour are to become open public space to help retain the character of these areas. Existing roads will be retained and the southern link road will enter the development through a ‘green gateway’. This will present the development as an ecologically driven design and indicate to both residents and visitors that you are entering an area with high stewardship values.


bio-sphere reserve

_ project one

This goal introduced us to the concept of a Bio-sphere Reserve Plan, which seeks to treat the entire area as a single system and therefore promote integration of natural systems and human development across the whole landscape. We also propose that each residential block and each catchment area should have its own community storm water plan and ecological treatment system at a range of scales. This will help instil stewardship values and encourage knowledge and value of local ecosystem services. In this design we must also acknowledge that each new resident will have an ecological footprint that exceeds the sustaining ability of the development. However we argue that by having a higher density of people than has previously been typical of Auckland subdivisions we are retaining more space elsewhere in the development and in the wider region for other land uses, such as agriculture or native forest, which could help offset these impacts. Additional to this, we have proposed that instead of having low density lifestyle blocks in the development, there will be large areas of land allocated solely to agricultural production and thus providing direct resource support to the high and medium density developments. This could take the form of farmers markets or other local produce stores.


aspect When considering the best place to build the new development, the direction of the slope that is to be developed must also be considered. North facing slopes are the best as they get sun for the majority of the day, giving potential buildings on these slopes a more desirable and healthier environment. South facing slopes are associated with colder buildings that only get sun during the middle of the day and are therefore less desirable for building on.

South Facing Land


slope Karaka has a topography that is dominated by gentle rolling hills sloping towards the coast, which are easy to build upon. However, within the site there are a few areas where the gradient of the land exceeds a 15 degree angle in which would therefore not be desirable for development. These bits of land have been put aside for public space.

Slope >15degrees


view points View points are placed on the development site to show what you will be able to see from a particular location on site. These will help to decided which places are suitable for putting buildings in, paralytically the buildings which are multilevelled.

water flow Currently, most of the watercourses in Karaka run through farmland and are subject to agricultural run-off and stock impacts. There are multiple rivers in a single catchment area, all of which flow either into the Karaka estuary or directly into Manukau Harbour. During rainfall events the water on the development will fall and be collected in particular areas of the development.

catchments Karaka has several different catchment areas, a few of which cross over the boundary given for the site development. This means that for any storm/waste water (or other runoff) treatment and management plan is to be successful it will need to extend to the whole catchment basin, not just the areas within the development boundary. This particular site only has one major catchment that covers the entire site, including area outside of the development boundary.

Water Catchment


sub catchments The development site consists of three different sub-catchment areas, all with different levels of capacity. This will mean that when development is constructed on site these particular catchments will need to be considered in the placement of buildings and other infrastructure. The level of water in these catchments will vary depending on the types of rainfall.

Low Medium High


land use capability Within the site boundaries the soil quality is uniform, with a good level of fertility across the majority of all the land. Therefore, the development’s agricultural landscapes can be situated almost anywhere across the site and still maintain and high level of productivity.

Soil Quality Type 2


existing vegetation There is little or no significant areas of native vegetation within the Karaka area. However, there is a dominance of mangrove communities in the coastal areas which help catch erosion and stop sediment getting in the estuary.

Mangroves


contours The site in which is to be developed does not have a large amounts of contours present as the site is reasonably flat. The majority of the slopes present on the site are down towards the coastal edge and in the central section of the site. The highest point present on the site is 16 metres above sea level with the lowest being 0 metres on the coastal edge.

Site Contours


constraints From the analysis of the abiotic and biotic factors that have shaped Karaka and in considering how these factors may influence the location and form of the proposed development, we are able to determine the areas where development would be inappropriate or undesirable. Factors such as south facing pieces of land have been put aside as land that would not be desirable to build on. All slopes that are greater than 15degrees that are considered as inappropriate to build on have also been set aside.

Land that is not suitable for building


build-able From the analysis of the abiotic and biotic factors that have shaped Karaka as well as considering the development constants, we are able to show the land which is considered the most appropriate and desirable land to develop. These bits of land include sites that have a slope smaller than 15degrees, as well as West, North and East facing blocks of land.

Land suitable for building

hard infrastructure

_ zoning

There will be two types of densitys present on the Karaka development. The first of the densities will be a high dendity zone. This will consist of buildings 5-8 stories in heigfht with 15o of these buildings being 14 stories in height. This zone will be a mixed use area with comercicial areas on the lower levels of some buildings (ideally the lower two levels) with the remaining space being residential. The second area will be a low high density zone. These buildings will be no higher than 3 stories and will be all residential housing.

_ karaka

The Karaka Development will be designed with people in mind; this will ensure that there is a vast number of public walkways, cycle ways and parks. Cars will not take priority on the site. The overall development will consist of two parts; one being a low-high density area for mainly residential use, being no more than 3 stories, and the other area being a high density area for residential and commercial use, with the majority of buildings ranging from 5-8 stories with a number reaching 14 stories high. The roofs of the buildings will consist of 50% green roofs and 50% photovoltaic panels, ensuring that electricity can be produced on site and water is collected for use in the buildings.


hard infrastructure

_ buildings

All buildings on the site will be constructed from environmentally friendly materials and locally sourced. With the environment in mind and ecology being important all the buildings will have green walls as this will help to soften the look of the buildings and provide an ascetically pleasing look. The buildings on the development will have either a green roof or a roof covered in photovoltaic panels. Ideally it will be a 50/50 mix of green roofs and photovoltaic panels. The green roofs will help to control rainfall with 66% of water falling on the roof being transpired, and the photovoltaic panels will help to produce electricity for a portion of the buildings in the development. Water will be collected from all buildings and be reused internally for flushing toilets and washing machines.

Buildings


hard infrastructure

_ circulation

The development has been designed for people and not cars. The main way of getting around the development site is by foot or bicycle. There are a large amount of wide footpaths and cycle lanes that circulate the entire site. This will help to ensure flow and easy transportation opportunities. To ensure the use of the footpaths and cycle lanes there is minimal parking on the roads. As cars do not take priority on the development there are only five main roads present. The main central road and four loop roads.

Footpaths Roads


green infrastructure

_ stormwater

Stormwater is an important part of the development, as there is no way around it and is something that must be dealt with. Swale’s and rain gardens will be installed between and along side all roads and footpaths to treat run off. There will also be storm water ponds and rain gardens though out the development for water treatment and containment from all the buildings and other infrastructure.

Stormwater


green infrastructure

_ vegetation

With the new development being constructed on the coastal edge of the Karaka site, the regions around the back of the development, including the central part of the development will be re-vegetated with natives. This will provide an enriched ecosystem and have the new development nestled on its outer edges.

Vegetation


green infrastructure

_ open space

There will be vast amounts of open space though out the development. All of this space will be publicly owned land and will weave its way though the buildings as well as going down to the coast. It will consist of open park land, courtyards and patios, sports fields and courts as well as fruit trees and public gardens not only for flowers but for vegetables as well. Also present will be storm water ponds and rain gardens weaved into the landscape. Some of these will create small ponds and lakes for the enjoyment of the public.

Open Space


karaka What is an Eco-City? An Eco-City is an ecologically healthy city. Eco-Cities are places where people can live healthier and economically productive lives while reducing their impact on the environment. They work to harmonize existing policies, regional realities, and economic and business markets with their natural resources and environmental assets. Eco-Cities strive to engage all citizens in collaborative and transparent decision making, while being mindful of social equity concerns. Eco-city development integrates vision, citizen initiative, public administration, ecologically efficient industry, people's needs and aspirations, harmonious culture, and landscapes where nature, agriculture and the built environment are functionally integrated in a healthy way.

_ eco city

Ecological Security Clean air, and safe, reliable water supplies, food, healthy housing and workplaces, municipal services and protection against disasters for all people. Ecological Sanitation Efficient, cost-effective eco-engineering for treating and recycling human excreta, grey water, and all wastes. Ecological Industrial Metabolism Resource conservation and environmental protection through industrial transition, emphasizing materials re-use, life-cycle production, renewable energy, efficient transportation, and meeting human needs. Ecoscape (ecological-landscape) Integrity Arrange built structures, open spaces such as parks and plazas, connectors such as streets and bridges, and natural features such as waterways and ridge-lines, to maximize biodiversity and maximize accessibility of the city for all citizens while conserving energy and resources and alleviating such problems as automobile accidents, air pollution, hydrological deterioration, heat island effects and global warming. Ecological Awareness Help people understand their place in nature, cultural identity, responsibility for the environment, and help them change their consumption behaviour and enhance their ability to contribute to maintaining high quality urban ecosystems.


transportation

_ bridge

A new bridge will link Karaka and Weymouth and be constructed. The new access road connecting Karaka with Weymouth will help to ensure good traffic flow in and around the Karaka area and help to ease traffic pressure points such as the Papakura on-ramp. The bridge will consist of a two-four lane road way which will include bus lanes. There will also be large pedestrian footpaths and cycle-ways on each side of the road. There is also the possibility for a future rail link to be put on the bridge but only if the population requires it.


transportation

_ ferry

In addition to the new development, a new ferry crossing will be put in place to help ease traffic congestion and provide a better public transport system. A key stop for the ferry will be the new Karaka development, the stop will located next to the new Karaka bridge. With the new Manukau Harbour Ferry running every half hour each weekday, computers will be able to gain direct access to Auckland Airport and Auckland CBD via the Onehunga to Britomart train line.
