Living with the absence- The endless story of ALNA

EDINBURGH COLLEGE OF ART MLA II

HAO PENG MAY 2020 S1804559 OSLO STUDIO . THE ENDLESS SONG OF ALNA

Design Statement

The Endless Song of Alna My site is the longest river in Oslo, Alna.

My project aims to explore what kind of landscape intervention is Alna needs to form A sustainable and sensitive landscape with high ecological and cultural values. This river flows through the Vollebekk area that I planned last semester. Like Vollebekk, Alna has been polluted by the industrial era which enlightens the city’s economy and prosperity. In Vollebekk’s landscape framework, Alna serves as a reopened river, providing extremely high ecological value for the whole outskirt region.

Why Alna?

When I first see Oslo, I did not know what kind of city I would meet. In the early autumn of last year, I finally feel this “Valley of God”. For me, the charm of Oslo is its topography, geology as well as biology. Fjords, water and forests form the basis of Oslo’s landscape. How did I notice Alna? Maybe it was because of the first misunderstanding. In the first field trip, I always subconsciously thought Alna was Aker. These two rivers located so close. Why one is popular, another one is a faded memory? When I started interested in Alna and began to search for information. I found, For years, the Alna was a “forgotten” river in the cityscape, which already existed for thousands of years, long before people settled along its banks. It starts in the Lillo forest, on its flow toward the fjords, the Alna falls 237m and forms the biological and blue-green connections in the cityscape. It passes through a cityscape of contrasts, where you find everything from native forests and diverse natural areas, also fallow the railway line, marking the stratification of society in the city of Oslo. I collected the history of Alna and found that as a forgotten river, Alna was used as a rubbish dump and sewage until the end of 16th century, until 1850, when the industrial era began, the river was hidden, completely forgotten and disappearing generally.

For a fast-growing city like Oslo, “the higher the degree of urbanization, the more fairy tales (the landscape) are withering away”. Alna’s story faded during rapid development and urbanization. From the planning scale of the city, Alna can reduce the pressure of the existing landscape due to urbanization in limited place through the design of the resilient and minimal intervention, and at the same time can regain the natural dynamic to deal with the uncertain climate change in the future.

- Pre Combining the history analysis of Alna, it is not difficult to find that Alna faces more environmental problem than I thought. The first is the loss of natural dynamic, which means Alna face the flooding crisis due to melting snow and seasonal rainfall. Because the shape of Alna is meandering feature, the changing width leads to the inability of store water and hold soil. Secondly, pollution. Unlike the direction of the Aker river, the northeast direction of Alna is almost industrial areas. Most of these industrial buildings were built after world war II, the Vollebekk industrial area established between 1945 and 1975, and the transportation build between 1970 and 1985 all caused pollution to the river. A large section of Alna run in culverts, drainage and landfills that were once planned along the river led to Alna still containing a lot of metal pollution, such as lead, copper and zinc. The last challenge is that there are many invasive plants on both sides of the river, these plants deprived of the possibility of local plant growth. The ecological value on both sides is greatly reduced. Therefore, I think that reopening Alna and bringing it back to the public can show the ecological value of Oslo.

During the analysis process, I also encountered challenges. Because rivers are different from other types of landscapes, the river is flowing and are visible to live. When I started to analyze Alna, I was afraid that the river would be restricted by me. In order to maintain the sensitivity to the river, I looked for various expressions and materials to display and experience the river and the surroundings. In these attempts, I tried cutting the foam board by myself, using clay to shape the dry and cracked ground, using gypsum to sculpt the uneven terrain, using the paper machine to shape the flow of the river and the texture of the mountain forest, and finally learning to use Linocut print to record my experience of the site. Original memories and feelings. I think that each trial process has brought me different inspirations. These production experiences make me feel that the distance between me and Alna is gradually shortening.

-IN

After completing the fieldwork, I need actual information and analysis to provide a basis for the formulation of the Alna strategy. My first analysis is to draw a 1: 3000 Alna. Hand-painting the terrain of Alna is a challenge, because the river is too long, and I struggled for a long time in terms of scale. Finally, the ratio of 1: 3000 was finalized, and the Alna was drawn with 6 A0 collages. In the whole picture, I extracted the ecological and social partition caused by the railway, which mainly formed polluted industrial zone industries. The shape of the contour and the meandering characteristics of the river. Then, the analysis of Mapping is closely related to my clean water strategy, because the design of topography purifies and transportation purify needs to be supported by the analysis of slope, elevation and surface runoff.

Then, the ecological strategy and basic structure are already available. In the whole river, I chose two sections for design. The first section is the Bredtveit area near the north of the Alnsjoen lake area, which is upstream of Alna. According to the existing ecological structure and biodiversity analysis of the upstream, the upstream part does not require many large-scale designs and measures. What is needed upstream is accessibility. The connectivity and accessibility of surrounding schools, churches, and kindergartens can enhance the social and educational value of this section of the river. Ecologically, the upstream is designed to purify the water body at elevation, and this purified water can provide certain services for plant growth in the community. The second river is a Bryn area close to Vollebekk and sandwiched between two industrial areas. The terrain of this area is relatively flat and can prepare for flooding. The pollution of the industrial areas on both sides can combine plants and ecological habitats. To gradually ease. In addition, the east side of this section of the river has an ecologically valuable urban woodland, and the horizontal connection can provide a green environment and more activities for the houses close to the industrial areas on both sides.

Finally, in the detailed design, I gave more consideration to the configuration of the plants. In my workbook, I have my choices for each habitat plant, as well as the hand-painted and characteristic analysis of each species. The drawing and understanding of the project allow me to provide a timeline design for the construction of Alna, ensuring the value that can be achieved in each time.

-OUT Finally, for this design by Alna, my outcome is a sensitive river landscape that can respond to unknown changes. The opened and accessible Alna will return to people’s daily life and become a place where people gather, rest and observe wildlife. Give people a chance to slow down and feel nature and life.

Series 1 “Serendipity”

After returning from Oslo, I tried to use linocut print and watercolour drawings to show the quanlity of the site. In this process, I selected different elements and made the first part of the fieldwork based on my sense of atmosphere.

In the second part, I tried to make models to show the natural elements by using recyclable materials, so I chose paper machine. The paper machine was used to demonstrate Alan’s flow and the texture of the forest.

In the last part, the carved plaster and the projected urban development have created a partition, which is also the huge social isolation and ecological isolation caused by the lack of reflection and consideration in the rapid development of City of Oslo.

First, look at alna from the structure. According to the plan to use alna as an element in vollebekk last semester, alna needs to be connected horizontally and to break the partition caused by the railway to achieve ecological continuity.

My whole concept and Strategy of Alna ,including 3 parts.

The First Part is about river flooding. There are two reasons for the flood problem that Alna is facing. The first is the sudden narrowing of the river, and the second is due to heavy rain. Therefore, in how to use the landscape to make the river more adaptable to flooding, the structure of the river itself is widened, and the use of stones to control different water speeds, so that the characteristics of the river ’s meandering can be maintained. The second is to create different habitats around the river. These habitats must have certain water storage capacity and serve biodiversity. Different designs are made according to different slopes when choosing.

The Second Part is the Strategy of Purifing Water, to realize the alna’s vision of interacting with people’s lives needs to improve water quality first. The first layer is Topography filter layer due to the topography feature, the Second Layer is vegetation Filter Layer focus on the habitats creation and the idea of “ Saving endangered freshwater pearl mussel” creating rich quatic habitats. The last filter layer in bio-wale layer, using to deal with stormwater storage.

The Last Part is the socio-ecological part, using urban framing, boardwalk,etc to increase the accessibility, engagement and educational value.

During 1000-1850, Latrines and waste water polluted the local groundwater, run-off from the local aluminium mining works and tanner’s shops polluted the nearby Alna River. Then, during 1850-1930, the supply of sustainable hydropower from the area’s largest river Alna, Akerselva and Lysakerelva. Until the 1980s, the waterways were considered problematic due to leakages from the sewage system, heavey pollution from emissions and spills. and as obstacles for efficient urban development.

The Alna river rises from 80m to 85m, and to the east is a nearly vertical wood, rising from 85m to 127m, almost a woodland cliif. Huge changes in elevation, along with the railway, formed barriers that made it difficult to access the Alna.

Seasonal Changes Visulization

Oslo, close to the Arctic Circle, is particularly beautiful in winter. People have long known friends with the cold environment, the silvery white earth and the occasionally not so safe roads.

The people of Oslo found different beauty from Oslo in winter.

They saunad beside the fjord and played on the snow-covered slopes. In the winter, upper stream usually covered by ice, and the lower stream is flowing water.

The river bed was exposed from time to time, and the sun hit the stones from time to time. Walking beside alna, enjoying the quiet environment. When the weather is good, people can follow the hiking trail all the way to the Lillo forest, overlooking Alna and Vollebekk.

Spring came very late, and the animals gradually began to wake up. New habitats born on both sides of the middle reaches of alna attracted upstream birds, gradually becoming denser waters and becoming home to invertebrates and fish. Schools and parents around Alna began to take their children to this river environment park, watching dragonflies, butterflies, and river volunteers to observe how freshwater pearl mussels grow. Residents began to cross the woodland and came to the alna morning run, listening to the call of birds.

From March to October, more and more animals can be observed. Snow and rain have gradually raised the water level of alna. People can gradually see more fish swimming along the upstream. The water lily in the water is blooming, and the sides of the river bank are yellow, white and red flowers .

In the early morning, there are animals passing through the forest from time to time. People started playing in the waterfall next to Alna and the established little bath. The river bank with lush vegetation drives away the summer heat.

Freshwater Pearl Mussel

Freshwater pearl mussels spend their adult lives anchored to the river bed, filtering water through their gills and improving the quality of the water for other species.

The freshwater pearl mussel is an endangered species of mollusc, found in clean, nutrient poor low-calcium rivers. They have a fascinating life cycle; their larvae attach to the gills of salmonid fish and ‘hitch a ride’ for up to 10 months of the year.

At around 3-5 years they will have developed gills and will be able to filter free-flowing river water.

(The wildlife trust) The freshwater pearl mussel in the river alna are going to disapper due to the water pollution, the concept here aim to recreat suitable submerged habitat which can save freshwater pearl mussel.

Upstream of Alna, according to mapping analysis, the trees are already very mature, and some of the waterfronts have already taken some measures.

Therefore, the main problem to be solved is accessibility and flooding. Secondly, many kinds of birds can be observed in the upstream, so during the design, we chose to add a number of medium to small semi-enclosed spaces according to the existing terrain, and constructed a series of amphitheaters to provide people with space to communicate . At the same time, there are many residential areas near the upstream, but people in these residential areas cannot easily enter alna, so a new plank road is provided for the people who live. Give people the opportunity to feel Alna.

The upstream and downstream have the responsibility to restore water quality, so the design process is mostly for the creation of ecological habitats and the configuration of plants.

This community was built in 1956, before this area was wooded. The structure and movement of the community has not changed since it was built, but it has passed my field investigation. I found that because of the primitive terrain, the community is very prone to surface water accumulation, and the community can lead to the river. Therefore, in the design of the community, sotrmwater is managed from the directions of delay, store, and filter. And designed some community garden to promote people’s communication. Most of the plants in the community have already matured, so these trees were not damaged during the design process, the original hard was changed to a lawn, and the pond was designed in the terrain depression to match the bioswale at the edge of the building Restructured part of the rainwater treatment method.

Observation Point During the field investigation, I once tried to climb to the highest point of this hillside, but because of the lack of roads and cluttered shrubs, not being able to observe Alna from a different line of sight became my biggest regret in field investigation . From the google map, I saw that there are exposed stones, which surprised me, so after doing a lot of case studies on the observation deck, I hope to be able to design a small place where people who hike can rest and escape the city Wooden platform. When screening different materials, I think that when natural rocks are combined with oak, which changes color with the impact of rain, it can show the art of landscape development in time.
