<ul><li><p>BIO FILTRATION CONNECTION</p><p>Helena Downey</p><p>Stage two of the Tamaki River Project. I have chosen to focus on issues relating to water quality. </p><p>1) To prevent further contamination. </p><p>2) To enhance water quality. </p><p>3) To educate the public regarding the issue. </p><p>4) To aim for overall increased sustainability/resilience throughout a selected area. Achieved in cooperation with the education through design theory. </p><p>OTAHUHUHELENA DOWNEY</p><p>Scale 1:50,000</p></li><li><p>Working with Megan Carbines, a marine sci-entist at Auckland Council has lead me to gain further knowl-edge about the marine life with-in the Tamaki Estuary and the huge ecological role they play.Research shows that New Zealand green shell mussels </p><p>are present in the waters in various areas throughout the river. Auckland Council use mussels to carry out a Con-taminant Monitoring Pro-gramme where they test for metal contaminants such as Arsenic, Cadmium, Chromi-um, Copper, Lead and Zinc. </p></li><li><p>tamaki rivercontamination E n h a n c i n g w a t e r q u a l i t y a n d p r e v e n t i n g f u r t h e r c o n t a m i n a t i o n b e i n g m y p r i m a r y o b j e c t i v e , I i d e n t i f i e d k e y a r e a s o f c o n t a m i n a t i o n .</p></li><li><p>e d u c a t i o n t h r o u g h d e s i g n</p><p>A concept which relies not entirely on the design itself, but the people who interact with it. By explaining the reasoning behind the design and what the positive effects are, people are more likely to have an appreciation towards it. In this case my aim is to educate the public </p><p>into why Tamaki Estuary is contaminated, how they can help prevent further contamination and what the positive effects my design will have. Placement of design is important for this concept to have effect. </p></li><li><p>before after</p><p>seas i de parkoutset</p><p>Seaside Park, Located on the banks of Tamaki River is a four-year transformation of a contaminated landfill into a wildlife haven. The design included a man-made reef and protective rock barrier, wetland area, an emphasis on water quality within the estuary, wildlife refuge, newly planted flora, walking tracks, recreational playing fields and a new stormwater retention basin. The 17.6 ha park is a highly visible and well-used amenity area and </p><p>an important recreational facility. Combining the location of Seaside Park offering its excellent coastal location, amenity values, residential housing, sporting facilities and overall public friendly park space with the identified contaminated area sitting north of the park, where Otahuhu Creek and Tamaki Estuary meet. This offers the perfect opportunity for me to build on the Education through design concept.</p></li><li><p>ota</p><p>hu</p><p>hu</p><p> po</p><p>rta</p><p>ge</p><p> history</p><p>Portage Road</p><p>pr i o r 1 840The Otahuhu portage, connecting the Waitemata and Manukau harbours, and the Waiuku portage, connecting the Manukau Harbour and Waikato River, enabled travel between Northland and the interior of the North Island. According to a plaque on the corner of Portage Road and Mt. </p><p>Wellington highway, this road is the shortest road in the world connecting two oceans (Pacific Ocean via Waitemata Harbour and Tasman Sea via Manukau Harbour). In ancient times, it was a track where Maori dragged their canoes between each harbour.

A rough estimation can be made to distinguish the amount of water being filtered per day. A standard mussel rope setup of this length would contain 4000 m of dropper line more or less with an aver-</p><p>age water depth of 5 m. Assuming we have 4000 m of line with the standard 150 mussels per m. That allows each rope to hold 600,000 mussels. Multiply that with 18 columns and you get 10,800,000 mussels in total. With each mussel fil-tering 360 L of water per day the total amount adds up to</p><p>3 , 8 8 8 , 0 0 0 , 0 0 0 Lo f w a t e r f i l t e r e d p e r d a y</p></li><li><p>o p p o r t u n i t i e sThese mussel structures would require maintenance in terms of laying the ropes, monitoring and replenishing stocks as natural mortality diminish the population. There is a newly established mussel recycling plant set in Nelson, Marlbor-ough. This plant removes any contaminants and converts the </p><p>shells into organic feedstock and fertilizer, creating the po-tential for shells to be transported there. Some research is developing, which looks at the use of mussel shells to be used in stormwater pits to absorb contaminants from as a form of treatment. Potentially shells could be used for this also.</p></li><li><p>3 m</p><p>Buoys</p><p>1-1</p><p>0 m</p><p> dep</p><p>endin</p><p>g o</p><p>n </p><p>wat</p><p>er d</p><p>epth</p><p>Water levelMussel ropes 0.2 m thick</p><p>1 m Sea floor</p><p>Supporting rope</p><p>c o m p o n e n t s</p></li><li><p>n z s o u r c e d e q u i p m e n t</p></li><li><p>Bibliography Amputch, A.

The 4-lane road infrastructure (Ti Rakau)seems to have one of the strongest impacts on its surroundings due to its scale and heavy traffic. There are numerous conclusions that there is no sense of living within commercial/industrial ar-eas and I propose on developing an idea to overcome peoples perspective over commercial/industrial areas by pro-viding an urban based projects for a more enhanced living conditions. There are many problems to consider, how-ever the primary aim is to counteract the on-going pollution caused from stormwater run-offs caused from roads, buildings etc. I feel that, by introducing low impact environmental urban designs with stormwater treatments, the current on-going deterioration will remain manageable and ultimately peoples immediate perception over these areas will hopefully change them to utilize all proposed designs as an enjoyable environment.</p><p>Living up new spaces</p></li><li><p>Context</p></li><li><p>Gray, unwelcoming, low vibrant, short of significant ecological beneficial vegetation and lack stormwater treatments are some of few that I en-countered throughout my site visit on East Tamaki, Pakuranga. As I mentioned earlier, the site lacks in what a successful environment would be able to provide and support the wants/needs of an individual. Rain gardens, swales, living walls (facade walls), retention ponds, business parks and many more implications can be introduced throughout the chosen site to ultimately accommodate both ecology and social aspects. Meas-urements, Site visits, GIS desktop research and further refinements are some of many primary tasks that I would need to consider. My site visits consist of capturing all possible opportunities that the site may offer for future implications and doing so, I could then make assumptions based on the information I gather during these site visits.</p><p>Site Visit Problem</p></li><li><p>Site Visit Potentials</p><p>All these images speak for themselves. These moderately narrow strips of open, flat yawns are ideal for development and it was unfortunate to find these patches of land underutilized with only standard, non-significant species of vegetation planted in low quantities.</p></li><li><p>Site Visit Potentials</p><p>Here are few snapshots of a potential business park where retention ponds, swales and other stormwater treatments can be used to implement an educational purpose on local members of business employees. I am hoping that within time, people are inspired and willing to take on a more environmental approach.</p></li><li><p>GIS Analysis Chosen site + Land use</p><p>Compiling GIS data and analysing their attribute/values can highly influential the overall outcome of a design project. A successful design requires full attention on various opposing constraints and limitations that may affect the design. </p></li><li><p>GIS AnalysisSurrounding vegetation + Open space</p></li><li><p>GIS AnalysisBuilding footprints + Road infrastructure+ Imprevious surfaces + 1meter contour lines</p></li><li><p>GIS AnalysisHydrology + Wastewater Flow+ Manholes + Elevations</p></li><li><p>As the first LEED Gold certified mixed-use industrial building, this 212,000 sq ft facility includes 18,000 sq ft of office space and common area, a 26,000 sq ft training center and a 135,000 sq ft warehouse with a 33,000 sq ft mezzanine.</p><p>Completed in October 2001, the project is based on energy efficient, sustainable design using recycled materials, non-toxic products and certified wood. This specific building consist low impacting environmental designs to address any on-site polluted run-offs as well as neighboring addresses. Honda has proven that a commercial building can be en-vironmentally friendly and energy-efficient while supporting normal business activities. </p><p>Stephen Epler Residence Hall is located at the southwestern corner of Portland State University. The building was designed with sustainable components focusing on inte-grating new technologies to get the greatest benefit from the sites wind, rain and stun characteristics. One of the design goals was to make stormwater management interesting and engaging for students and residents of the building. This is a very important factor to consider. By encouraging people to experience some of the process in which the storm-water treatment works, this will have a special influential effect on people, hopefully changing their perception over East Tamaki. The design consists of visible stormwater systems on an open courtyard. The rainwater is guttered through and directed to multi-ple planter boxes, this is where filtration processes initiates.</p><p>Case StudyPortland + Gresham</p></li><li><p>Landschaftspark is a public park located in Duisburg Nord, Germany. It was designed in 1991 by Peter Latz, with the intention that it work to heal and understand the industrial past, rather than trying to reject it. This case study is more of a reference of how and what can be achieved despite being in an old rusty industrial area. The vibrant atmosphere of on-going events, recreation and public activities keeps the park resistant. Given time, I am hoping that my site can take on this notion of approach.</p><p>Case StudyLandschaftspark in Duisburg Nord, Germany</p></li><li><p>Proposed plan design</p></li><li><p>Major proposed design 1Streetscape</p></li><li><p>Perspective Streetscape</p></li><li><p>Major proposed design 2Business park</p></li><li><p>Perspective Business park</p></li><li><p>STORMWATER TREATMENTOTARA CREEK RESTORATION</p><p>-Ji hoon Park-</p><p>In our research in part 1, We have noticed some serious ongoing pollution problems that have been identified through our research in Tamaki estuary. Untreated storm-water and expansion of development &amp; earthwork was the major problems that was increasing the level of pollution and chemical concentration in the water around the Tamaki estuary. Due to on-going development and expansion of population, impervious space is increasing and is causing serious and various stormwater problems worldwide. This is a serious issue that will continue to grow and therefore, will need to be addressed immediately. Without a well-designed stormwater treatment solution, we will end lose majority of our usable waterways and ecology. The Otara creek is a great opportunity for development as it is surrounded by mostly the residential areas and is easy to access.</p><p>Through the site visits and research it was easily noticeable of how badly the site was being misused by the surrounding community which shows the level of awareness concerning basic environmental issues and their values of the local community.</p><p>By looking into series of GIS maps of the site and several case studies worldwide that are deal-ing similar problems, I will be able to find a solution that is suitable for the Otara creek.</p><p>Otara creek was predicted as a creek that is most likely to be seriously polluted around 2060 with many illegal sewage spillways and thereby high concentration of chemical levels. By providing adaptable solution for this site will bring more attention and awareness from the local community and will be able to expand the project further around the upper Tamaki estuary due to its outcome.</p><p>The image from one of the article concerned about the illegal dumping of wastes in the water.</p></li><li><p>GIS MAPSMap 1.
