Regenerated Flora and Fauna.

Key Stone Specie

Transect: Highbrook Drive-Otara Creek

Key Stone Species are symbols of diverse ecosystems and healthy bush vitalities. Auckland’s key stone species are tui’s and bellbird’s.

A

Key Stone Specie

Kereru

- Kereru inhabit a wide variety of forest types: podocarp-broadleaf forest, beech forest, second growth native forest regenerating after logging, small forest remnants, and exotic plantations (especially those with a stream and native shrubs and trees). They also occur in farmland shelterbelts, urban parks, and rural and suburban gardens.

Fantail

- Fantails exhibit wide tastes in habitat; while the majority of species are found in rainforests fantails exist in most available habitats from deserts and mangrove forests to highly modified agricultural and urban environments.

Tui

- Tui prefer broadleaf forests below 1500 metres but will tolerate quite small remnant patches, regrowth, exotic plantations and well-vegetated suburbs.

A

Oystercatcher

– Oystercatchers use a wide variety of different coastal habitats. Most commonly sandy beaches, sand spits, shell banks, and rocky shorelines.

Bellbird -

Bellbirds live in native forest and regenerating forest, especially where there is diverse or dense vegetation

Key Stone Specie

Silvereye - Silvereyes may occur

Revegetation –

By re-vegetating Ngati Otara Park it will help prevent further degradation of the land and water. Native vegetation provides shelter, feeding, breeding and roosting site for native animals. Using Flora such as Kauri and Kahikatea will reinstate and improve native vegetation, provide habitat, provide connectivity between remnant vegetation and improve the quality of the soils and creek.

6

Wetlands – Submerged water plants, emergent water plants, surrounding trees and

shrubs all play a number of roles in a wetland to contribute to water purification, flood control and shoreline stability. Wetlands also are considered the most biologically diverse of all ecosystems, serving as homes to a wide range of plant and animal life. Flora in a wetland such as toetoe, clubrush, flax, jointed twig rush, mahoe, nikau etc., provide a food source for native fauna, habitat for invertebrates and they also carry filtration capabilities.

in almost any wooded habitat, especially commercial orchards and urban parks and gardens.

Our design focuses restoring the native flora and fauna to Otara. This will consist of approximately 50 hectares of revegetating native bush to three key areas: Highbrook Park (Pukewairiki crater), Ngati Otara Park and the Contact Energy Site surrounding the lake. Through this revegetation of the site the natural ecological processes will begin to clean up the site while creating a native oasis of flora and fauna that not only benefits the community of Otara but all of Auckland. In addition, a network of walkways and cycle ways will be implemented throughout the design to provide an interactive experience of the patch. A series of wetlands and filtration devices will be installed in the upper estuary to catch the sediment in the runoff from the wider catchment. This will create an Otara that will service the future generations to come as a naturally beautiful, vibrant reserve, a reserve the community will be proud of and will be at the forefront of urban, ecological remediation design.

By removing the weir and restoring the lake to the natural estuary processes through staged implementation, the waterway can become a place that is ecologically healthy and an asset for the local community. Currently Otara Lake is polluted and unusable for the local community.A buildup of contaminated sediments has occurred because of the weir, and it was with this in mind that we approached the problem. By maintaining the weir and lake, remedying this situation will take considerable time and money, which will also require ongoing maintenance costs in the future for the community. Dredged material from the lake is used to create wetlands for filtering polluted runoff as well as a connecting island to Highbrook. Dredged material is also kept and used onsite as a construction material in the form of mudcrete. Contaminated land from the landfill is also capped with mudcrete in order to halt the leeching into the waterway, and planted with native vegetation. We also felt that it was very important to relocate the marae from this contaminated land to the rehabilitated coastal edge in order to create a sense of place and connection to the waterway.

CONCEPTUAL PLAN

KEY 1 - WE PROPOSE FOR THE EXISITNG LARGE SECTIONS TO REMAIN WITHIN THE GREEN HEART OF OTARA. THE UNITARY PLAN PROPOSES THIS AREA TO BECOME INTENSIFIED WITH SMALLER SECTION HOUSING. WE FEEL THESE LARGE SECTIONS SHOULD REMAIN INSIDE THE HEART OF OTARA TO HELP REDUCE THE IMPERMEABLE SURFACE AREA WITHIN THE CATCHMENT. THESE SECTIONS WILL ACT AREA FOR SOAKAGE THIS WILL HELP REDUCE THE EFFECTS OF RUN OFF ON THE LAKE AND DIMINISH THE CARRY ON EFFECTS TO THE LAKE.

THIS IS A POSSIBLE LANDFILL INTERVENTION WHICH COULD BE APPLIED TO THE SITE. THIS IS A CONCEPTUAL PLAN OF A RECREATIONAL SPACE AROUND OTARAS PAST LANDFILL. THE IDEA OF CAPPING THE CURRENT LANDFILL WITH A LARGE UNDERGROUND WALL TO CONTAIN THE LEACHATE FROM THE SPILLING INTO THE SURROUNDING WATERWAYSAND CASUING FURTHER DEGRADATION TO THE LAKE. RE-VEGETATION OF THE LANDFILL SITE WILL HELP CAPTHE AREA AND PREVENT FURTHER SUBSIDENCE. PLANTING IN THIS AREA WILL ALSO HELP REDUCE CONTAMINANTS FROM THE LANDFILL THROUGH THE EFFECTS OF PHYTOREMEDIATION.

2 - TREES WILL BE PLANTED DOWN THE MAIN STREETS OF OTARA. POROUS TREE PITS WILL ALLOW FOR RUN OFF TO BE FILTERED INTO THESE SECTIONS. 3 - POROUS LANES AND STREETS ESTABLISHED THROUGHOUT ADDITIONAL DEVELOPMENTS.

PERSPECTIVE - FROM HIGHBROOK TOWARDS OTARA

PERSPECTIVE - OTARA RD. HIGHBROOK CONNECTION


Otara will become the green heart while the quality of the lake, occupations, housing and green networks increases. We look to propose a green heart concept to Otara where we will intensify the coastal edges with terraced housing and creating an internal catchment where the large lot housing will remain and low impact urban design features will be installed as a filtering system to the lake. We would like Otara to become a link in Auckland’s linear city where a new node of intensification on Bairds Road next to State Highway One will promote amenity and jobs to the area. We propose to squeeze part of the lake by dredging the western part of the lake and placing the sediment on the northern and southern sides. The sediment will be planted to create wetlands and salt marshes as addition to the mangroves, to allow for filtration of the sediments enhancing water quality to create a healthier estuarine ecosystem. A pedestrian bridge will be implemented in to the site where Otara road ends to complete the connection from Ngati Otara Park to Highbrook Park; the walkway will run around the circumference of the lake interlinking with our intensified housing.

O TA RA LAKE + WAT E R WAY S Our proposal is driven by the desire to reconnect the Otara community with their waterway through nature, culture and industry.

We propose a three-part Masterplan that can be completed in stages throughout the next 30 years. Stage One aims to reconnect the Otara community with its waterways by enhancing and restoring the health of the lake and surrounding ecology, through the use of bio-filtration and bio-remediation techniques. Additional to this, we proposed enhancing the existing pedestrian network by connecting the smaller community pockets to the main walkway, completing the shoreline circuit and bridging the estuary between Ngati Otara Park and Highbrook Park. Stage Two involves creating a culture-driven platform for place-making through passive and reflective interventions such as the symbolic rebuilding of Te Puke o Tara mountain and more dynamic community spaces such as the Waka-Ama pontoon, Marae and new community events center. In Stage Three we have integrated industry into our proposal as we believe it is, and will continue to be, an important part of the Otara community. The introduction of a bio-textile farming industry as well as the creation of a new business park will provide an economic boost to the area and become a large source of local employment. Additionally we propose the current Contact Energy holding pond to be refitted as a wetland to filter industrial runoff before it enters the lake.

Otara Creek project design is based on the theme of the ecological cycle, creating a natural river landscape restoration project type. There are multiple nodes landscape along the river for water pollution, and ultimately a “pearl chain� connected by greenways.Among them, the main design points mangrove wetlands, plantations, cattails Park, Maori cultural plaza plots. Mangrove wetlands purify the river, mud and cattails garden plantations silt from the river, so as to achieve the purpose of recycling.

RE-ENGAGE

THE ŌTARA COMMUNITY PROJECT A Local Project with Regional Benefits The two main goals we aim to achieve through our project is the restoration of the degraded stream ecology in the Ōtara catchment and providing employment to the youth. Making up to 58% of the total population, we recognized the youth as Ōtara’s biggest asset. Ōtara lake sits at the bottom of a massive catchment with over 72 kilometers of waterways discharging straight into the lake, bringing with it all the contaminants and sediments from farms to residential and industrial zones. Looking at Ōtara creek, from Sir Barry Curtis Park to Highbrook Park as a test model, we aim to set a template for the entire catchment to help reduce and over the years resolve the problem of the high level of water pollution. By mobilizing young people in the stream restoration project; The Re-engage Project, transfers power to the community to kick-start a movement that will improve the environment, clean up the lake and provide the youth with necessary skills to become stewards of their community.

Introduction Otara lake restoration landscape design is in the North Island of New Zealand South Oakland Otara lake. Otara lake was formed in 1968 and a perennial water storage dams results, Otara Lake is about 50 hectares (ha) in area and receives runoff from a catchment area of approximately 3,500 ha. The construction of the weir and the subsequent changes in the flushing characteristics of the lake has resulted in a number of significant changes in the lake environment. The impoundment resulted in sedimentation within the lake, and the changes in the tidal regime resulted in expansion of mangrove distribution with Otara Lake. Copper, lead and zinc pollutants from light industry to directly or indirectly lead to a decline in water quality of discharged water, land fill leachate increased River pollution.The gap between rich and poor of local residents have led to estrangement, rich region upstream to downstream water dumping causing water of the poor areas getting worse. Our design philosophy is to control pollution, improve water quality to improve Otara lake environment, so as to provide comfort and convenience at the same time to teach the local people to the lake with the local people, preliminary planning in 50 years to let people get rid of the habit of littering, having planting and love Forest Education for adolescent, narrowing the wealth rub board psychological barriers, fundamentally eradicate local environmental problems Otara.This design use the bike trails series "gem chain" to connect the various landscape, places offer training place for people and to enjoy the beautiful scenery.

ethnic groups in the manukau region including otara compared to greater auckland and new zealand as a whole

the otara demographic : The young ones! The 2006 and 2013 census figures confirm Ōtara’s position since the 70’s as NZ’s most ethnically diverse, and youngest suburb, with over half the residents under 25 years. It is a culturally diverse area which demands solutions which take into account the cultural narrative of the area. While it is an easy target for media and others who wish to portray it as the Harlem of the south, even a handful of field trips have exposed us as a class to a strongly committed community. Recent initiatives have had marked success, including Garden to Table and the Ōtara Health Charitable Trust, while others such as the Glenn Family Foundation are also following. The demographic features combined with other possible future trends make this potentially an extremely influential area for Auckland in the years to come, while the high percentage of ownership of houses by Housing NZ means that larger scale interentions are possible with government assistance.

phytoremediation as a solution for otara Phytoremediation is a technology that utilizes plants to remove and degrade contaminants found in soil, groundwater, surface water and atmosphere. Plants have the potential to be useful in wastewater and soil cleanup, due to their ability to evapo-transpirate groundwater, and produce enzymes that help in the degradation of contaminants found in soil and water. Due to the high toxicity of leachate, phytoremediating plants would have to be used as a subsequent process in the treatment of toxins (Granley & Truong.2012) Plants can also be used as a natural rhizomatic cap for a land fill. Through dense production of rhizomatic and capillary roots, hybrid poplar trees have the ability to provide a dense matting that prevents water from penetrating into the core of the land – fill. Natural caps have the potential to replace synthetic caps, by creating a “sponge and pump” system water is discouraged from penetrating the caps. ( Poplar technology)

above: ethnicity in papatoetoe/otara ward as in 2013 census

These systems used in a combination of rain-garden/ swales and wetland interventions has the potential to provide a natural environment for cleansing of leachate but also provides habitat for local wildlife, improved aesthetics of the site, and reduced operational and maintenance costs. By creating a closed loop system that collects the leachate aswell as road runoff that is then applied to the capped landfill, any potential of leachates being deposited in the Otara Lake are prevented.

the catchment

The total area of the Ōtara Creek catchment is 3,487 Ha. According to the Manuakau City District Scheme this is broken into 1363 Ha of Residential (including schools and reserves), 324 ha Industrial, 22 ha Commercial, with 750 Ha remaining for future development. Ōtara Lake is approimately 50ha in size, formed by the addition to the creek of the weir in 1968 (as above). The top of the weir is approximately at sea level; it is over topped around half tide each tidal cycle, allowing water to flow in and out of the lake. With the lake unable to fully flush out both sediment and additional leachates have severly affected the quality of the lake, leading to a loss in lifestyle for the residents -fishing and playing in the water are now a distant memory. Several subcatchments can effect the quality of the lake, predominately Flatbush, but including: Mayfield, Lorien, Glibert, Rongamai, Hillary, Power Station (Hellbays), Spring (Leonard), Kerwin, Lovegrove, Ngati, Ōtara Stream, so any remedial measures potentially have to take into account a large area.

Ōtara already has quite a good area of open space, the issue however may be quality/useability (map inspired by the GIS work of Shayne Noronha)

otahuhu B/ contact energy In 1968 the then NZED opened the Ōtāhuhu A Power Station. While this has been decommissioned the Ōtāhuhu B is still in operation today. Ōtara Lake is a result of the weir used by this power station (or Contact Energy) to control their intage of water, used in the process. Contact cool the water, then once it has reached a certain temperature return it to the lake below the weir. The presence of the weir has led to silt build-up, mangrove growth and other side effects the community feel are undesirable. Contact Energy were signatories of the 1994 Accord, but as yet nothing has happened.

Ōtara is a compact suburb, with less than 1500m from town to lake encompassing retail, education and housing. Hence it has the potential to be an extremely liveable, connected suburb (map inspired by the GIS of Shayne Noronha)

This study concentrated on the connection of Otara in South Auckland to Motutapu Island in the Waitemata Harbour and to the Pacific Islands: physically, culturally and historically. The idea of a new axis and Tamaki connection enabled us to create a strong sense of identity and a new focus for the community. This new axis along Otara Road formed a strong link to Motutapu Island, long held wahi tapu site of the Ngai Tai Iwi. It reconnects the existing city centre to the Otara Lake. The new road intensifies the residential and commercial zones, reinforces cultural diversity and retains education and employment in the area. Ecological improvements will be made through a series of interventions employing phytoremediation to the restore the health of the waterways. Re-appropriation Otahuhu Power Station A will serve as a new culture and arts centre that will raise the profile of Otara and bring valuable investment and interest to the area. By connecting Otara township and the lake to the Pacific, Otara will become the new ecological and cultural centre of South Auckland. This design will inspire the community and create a strong sense of identity and reinforce Otara’s cultural connections.
