INTRODUCTION Project Background

As the global population increases from around 7 billion currently to 9 billion by 2040 the world will see widespread urbanization, conurbation, and formation of megacities. The rate at which this process is occurring is ever increasing and as such urban planning and solutions to problems require new tools for effective intervention. This project was an introduction to both existing theory on urban analysis and growth as well as to methods of analysis. For these methods we selected the Grasshopper plug-in for Rhino as our software of choice.

INTRODUCTION Arrival City Selection

The country of Nigeria lies in the crook of Africa, and is home to many different regions and climates. This project specifically focuses on the coastal city of Lagos, found in the state of Lagos. It is the second largest city in Africa, both in size and population. As a coastal nation and city, Lagos thrives in a symbiosis between the water, the people and the landscape. The city of Lagos is faced by several major issues: a lack of infrastructure, constant flooding, and a serious issue with pollution. These issues all have a different cause and effect relationship with each other, and the study of these things eventually will lead to the suggestion of a prototype to “solve” some of the problems. The lack of infrastructure affects several aspects of the city and the population in Lagos, from the inefficient waste management system that exists to the lack of quality road ways. Though the State is tasked with the pick-up and disposal of waste and sanitation, the system does not work outside of the “planned” areas of the city, and sometimes not even there. When it is picked up, the waste is taken to the main sanitation site in the northern portion of the mainland or the smaller secondary sites found around the mainland and on the eastern portion of Lagos Island. Due to the proximity of these waste sites, residents of undeveloped areas are often forced to dispose of their waste in the rivers, Lagoon or the surrounding landscape, damaging the environment, the water sources and their settlements. Due to the nature in which the informal settlements often crop up in, they lack the infrastructure that is found within the city itself, though this is not an issue only in these areas. They lack paved roads, electricity, sewage systems, plumbed water, and the like.

Lagos State


This map of Nigeria shows the city of Lagos as the “Arrival City”, a concept that explains the sudden and extreme boom in population that is happening in numerous cities across the world. Here, it shows the city of Lagos as the migratory destination for numerous villages scattered across the state of Nigeria. These people move out of their villages and travel towards the city in hopes of finding better lives for themselves and their families. They are often forced to seek out work in the city due to conditions in their home villages, which limits their ability to raise and support families.

MAPPING INTRODUCTION

To begin, the research was focused on information and data from the city of Lagos and the surrounding areas that was predominant and easily accessible. Early information was often taken from satellite images of the area, which allowed for the identification and mapping of things considered important – like the informal settlements which dot the landscape. Also considered was what a “buildable slope� might be considered, and though it was decided that <15* was acceptable, it was also discovered that this does not apply to Lagos and the flat topography found in the area (where the majority of slopes in the area were <6*).

image 1 During the 15th century, more than millions slaves and people are exported and imported to Lagos due to the unique geographic position, sitting on the edge of Africa and connecting the US, Europe, South America and Middle East. Lagos then rapidly turns into a massive populated city by shaping the city itself. Within the state, cities keep breaking down and forcing to the south coast.

The next point of emphasis was the water that surrounds the city and general area, found in the Lagoon and its two main rivers, the Obo and Obun. The Lagoon is subject to tides, the rivers which empty into it, as well as the rain run off that reaches it. The constant flooding in the area is a direct result of these factors, combined with the flatness of the topography. It is also important to discuss the pollution levels of the Lagoon and rivers, due to the lack of infrastructure found in many areas of the city, as well as the heavy industrial areas that are located there. Other preliminary concepts and directions that were studied during this phase included: surrounding land use, road types, the flora and fauna found in the area, construction types and the like.

MAPPING COMPLETE ROAD NETWORK

The road networks became a very important aspect in the study of the flows in the city of Lagos. The study evolved from the organization of roads based on levels of connectivity (from highways, to major roads, to minor roads, and continuing on down), to the study of the “block” and how it and the spaces that it created were organized. Based on the “Streets & Patterns” reading by Stephen Marshall, the image 1 blocks were then organized further into types (of the A-D variety).

MAPPING TRANSPORTATION

This map shows the major transportation routes and stops throughout the city of Lagos, and the immediate surrounding area. The dashed line represents the major bus routes through the city, and although these are not the only routes that exist within the transportation system, they are the “main” routes. Also shown, as black boxes, are the main bus depots. Not included are the numerous stops found along the route, and other routes. The three ports are marked at the bottom of the page, and the larger airport is marked towards the middle of mainland Lagos. This is important, because it shows the disconnect that occurs outside of the dense city center, where most of the informal living settlements arise. There are transportation routes that go near some of the larger slum areas, but they are not afforded the same kind of access as the other image 1 “planned” parts of the city. Airport

WATER DEPOTS & WALKING DISTANCES

This map is a diagrammatic representation of the water depots found in the greater Lagos area, and their direct routes. Each circle represents a distance from a central point, which is the water depot, as a diameter. This distance is being considered a casual walking distance, at ½ a mile. As some of the depots are close to each other, their walking distances overlap and create a larger circle. The routes depicted by the dashed lines are the simplified version of the actual routes that water would take, if it were being piped through the system and to Lagos Island. This is important, due to the fact that the “safe” water available in the city is often piped in. For 11% of the population, it is piped > 1km, and for the other 89% of the population it is piped < 1km. It is thought that only 60% of the city population has access to “safe” water.

Walking distance to individual water depots

FLORA & FAUNA Nature has a large impact in every community, both in beneficial and detrimental ways. By mapping the dispersion of usable resources (such as trees, and shrubs), there could possibly be some benefit seen to the community surrounding those areas. We concurred that this should be represented better.

MAPPING MAKOKO & FLOODING

The rivers in the area of Makoko are notorious for their tendency to swell with water and flood over the banks, due to the lack of slope found in the topography. This combined with the lack of water run off and road maintenance allows the water to run rampant, and use road ways as channels to run further in-land.

TYPICAL INFORMAL HOUSING SETTLEMENT CONDITION After enough time and difficulty with dealing with large file sizes mapping within the entire city an assessment of the informal housing condition served as a waypoint for our continued analysis.

Image 1 As Lagos expands the space available within the city decreases and rent prices escalate. Government continues to push out squatters and illegal housing. The result is that arrival cities fill up the areas between the “cracks� with informal housing. These communities are typically set back from the street, area smaller, more randomly organized, and of poor quality materials.

image 1

Image 2 The crisis is further escalated as these few spots that many people settle into are areas that were open because they were less desirable. They are prone to flooding, are often locations of garbage dumping, and are less accessible. The positive side of this is that these people are the strong-willed, the brave, and the resourceful. This results in subcultures that thrive on innovative small business ventures that make the most of the resources available. Solutions to quality of these communities start with supporting this subculture. LEGEND

MAPPING ROUND II

When quickly gathering data for the city as a whole proved more challenging than our schedule allowed we quickly moved on to the next stage by narrowing our focus to Ilado Island to the South of Lagos.

20


LAND USE

The focus led to the mapping of how the land was used throughout the localized region of Lagos, primarily focusing on Tin Can Island, Snake Island and Ilado Island. For the combined area, the mapping consisted of Industry, Dense Vegetation, Light Vegetation, Developed Land and Exposed Soil. The purpose of this mapping process was to locate areas that are appropriate for expansion, which would include the Low Vegetation and Developed Land as important considerations.

MAPPING FLOODING DISTANCES

The only real difference found between the flooding on the mainland and the flooding on the island lies in the fact that the island is completely surrounded by water. The rivers flood annually, and in the instance that they rise 3 or more feet, almost all of the coastal settlements would be displaced and damaged.

image 1 This diagram map shows the amount of the island that would be covered if the river were to flood 1 foot, 2 feet image 1 or 3 feet.

RAIN RUN OFF

Due to the lack of topography found across the city of Lagos and Ilado island, the rain has little option to “run off� the land and into the rivers. This causes the water to pool across the Island, which can become quite hazardous due to the lack of infrastructure also found on the island. The combination of the flooding and the water pooling seriously restricts the amount of buildable area found.

INDEXING INTRODUCTION

The next phase, Indexing, evolves from the previous phase by studying the relationships between the different groups of information that were mapped. The focus of the project then turns to the informal housing areas known as Makoko (on the coastal side of the mainland) and Ilado Island (found south of the mainland). In these villages, the water continues to play an important role in shaping the clusters and the infrastructure found there. Seen in both areas and other spaces across Lagos, the flooding determines the gradient of housing types and the hierarchy of social standings. Between the flooding, swamp lands and dense city fabric, the desirable building areas are extremely limited. Access between Ilado island and the mainland is limited to a single dock and the ferry system, as well as personal docks and boat use, both of which cluster on the northern central side of the island. This further effects the building zones on the island, as one must live within walking distance of the coast to have access off the island. At present, this has heavily affected the flow on the island. This concept can be seen in the paths across the island, and the alleys that carve out the villages.

26


BUILDING PROXIMITIES TO RIVER The areas of the Island which contain the highest density of informal settlements are extremely close to the rivers and other forms of water. Due to this proximity, the housing is in danger of being damaged or destroyed by the flooding. Entire sections of the villages are washed away on a semi-regular basis, requiring the inhabitants to start over and rebuild. Due to this, it was decided that immediate proximity to the river is not necessary.

image 1 image 1 This diagram map of the island represents the proximity of the buildings to the river, and grades their distance by safety. image 1 POOL HEIGHT

<500ft

500-600ft

HOUSING DENSITY The high density of the informal housing clusters on the island causes the residents of the area to be tightly packed together. Due to this, any incident (fires, floods) effect many buildings in the area, instead of just singular units.

INDEXING DISTANCE TO PUBLIC SPACES

The study of how and why people settle the way that they do evolved to include the consideration of the spaces that are formed by those settlements. These kinds of spaces that are created could serve a public function, like town squares, markets and other kinds of open public spaces where people could gather. Across the island, the proximities of buildings and residences to these necessary open spaces were measured. Everything that was considered a close distance was within <100 feet, while anything too far away was >500 feet.

DISTANCE TO MAIN DOCK As the dock and Ferry route is the main way off and onto the island, it acts as an “anchor point” for the island. The informal villages expand from this point and the closer the proximity, the better the land. Due to the size of the island, most of the villages are within moderate walking distance. This excludes the northern point, which is somewhat segregated from the rest of the communities on the island.

Contour Elevation Gradient and Relative High Ground

By creating a contour gradient from the high to low point this forms another way of analyzing the favorable higher ground on the island.

INDEXING NEIGHBORHOODS

The study of neighborhoods evolved as a consideration of how and why people settle as they do, considering tendencies. The self-organization that occurs on the maps shows this type of patterning which leads us to surmise that like settles with like, to form these communities within communities. The lines between the “geometric center� of each block represents the proximity to one another, and shows the relationship that exists there.

INDEXING POPULATION GROWTH ON ILADO ISLAND

Without accurate population data, the growth rate of Ilado island can be measured by the developed and developing areas. The boundaries of the developed areas were traced from the satellite images shown from 2000, 2006 and 2013 to form a growth rate that were then averaged to a yearly rate and represented on the map.

INDEXING CONSTRUCTION TYPES

To derive usable construction type information, satellite imagery were traced of all the buildings on the island. The next step was to distinguish between observable variations of construction types. Categories were decided as follows: Thatched and old metal roofs (which were difficult to distinguish between) Metal roofs Newer metal roofs Buildings under construction The differentiation between building areas were then converted to circles image 1 of the same area as their base building contour. This makes it easier to compare the sizes between buildings.

The construction type by building area can be used to distinguish multiple social hierarchical settlement patterns. The construction type may be based on time since establishment, distance from resources or distance from major roads. Construction types per region have trends which indicate the typical social status of the inhabitants, and where people will tend to settle upon arrival to the island. Notable trends include the following: Higher quality homes tend to be in longer established, further from the coast, and further from easily accessible resources. There is a greater quantity of thatched or metal roofs in the northeast corner, which also has the nearest proximity to the coast.

Within each informal housing cluster, blocks were estimated based on the distance between houses and what was surmised could be considered an “alleyway� or path. Shortest Walk was used to draw from the center of each block to the main target of each individual section.

MESHING INTRODUCTION

So far, the processes completed could all be considered “layers” for the final portion of this study. Mapping arose from the collection of data, and Indexing arose from the combination of those maps. Meshing revolves around the same additive concept and process, because the combination of certain groups of information allows us to make informed decisions about the island, and draw conclusions that would not normally be possible or realistic. These conclusions include the understanding of what could now be considered “buildable” areas on the island, based on the information that is being combined. The idea behind this phase for our group was to create three separate mini-meshes from each section of study (Environmental, Flows and Programs). The final step is to combine these mini-meshes into a final mesh, to achieve the final “buildable” areas.

MESHING FLOWS, GROWTH, and BLOCKS

This index was used to draw out the relationship between flow routes blocks and settlement growth patterns. This is combined with the concept of village cluster expansion as a “flow� in its own sense, and how it represents the movement of a community and how the individuals make their spaces within that community.

OVERLAYS FOR MESH

This mesh differs from the others by taking land use into account as well as community gather points to distinguish between optimal and less optimal but still desirable zones for expansion. It also indicates the existing developed regions that are at risk and could benefit from built up terrain. Finally it shows areas that already have a buffer from flooding of mangrove trees or forest.

CONCLUSION

After the completion of the Meshing phase and the “Final Mesh”, the areas that were shown to be available for development were taken under consideration for the next phase of the project. The next phase involves the development of a prototype intervention, which would then take under consideration the major site influences, whether they be positive or negative. Essentially, the goal is to design a “solution” to the issues that were raised in this study while considering the locale and population and their needs. The main driving goals include the development of a sanitary and safe living conditions, while fostering the density and community aspects that are already found in the village clusters on the island. Continuing to consider the construction typologies found in the area will create a image 1 cultural cohesion, while allowing the new arrivals some control over the construction of their own homes.

MODEL Explanation

Our model ran into many complex problems that required a simple solution. The goal of the model was to, in three dimensions, model the overlay of indexes and weave the areas. In this process we need a transparent material that would be cut able yet rigid. The resultant material was 0.10” Acrylic that was originally in an 8’X4’ sheet that we had assistance from Ace Hardware in the cutting process down to 1’X2’ pieces. This was then ran through the laser cutter to shape to Ilado Island and the water off site. The next problem was supporting the layers, as such we needed a base and risers and supports. In this we used 3/4” plywood and 1/4” Steel weld wire that was originally in a 6’ length that was cut down to 8 ½” lengths. The plywood was cut from a 2’X4’ sheet into two 1’X2’ pieces that were laminated together and planed smooth on the edges. The steel was cut with a dremel and vice then ground smooth on the edges and rounded on one point for the ease of sliding our meshes over. The Spacers were achieved using 5/16” inner diameter brass pipe that was cut to a 1 ½” length with a torsion cutter. This came up with a problem in itself. The cutter would crimp the ends of the pipe making it to narrow to fit over the rod. The resultant solution was to slowly cut the pipe and grind out the bevel.

56

The process from there was to create a blank maquette of our mesh and to drill holes through the first layer of acrylic. As Adam and Cody started, it became apparent that the pins we were to use for the model were too small for the holes we had drilled, and we needed to fill and glue the pins in place. Another problem arose when we tested glues on a broken piece. The Super glue from Hodgins frosted the acrylic when it dried, was hard to stop from spreading but was the quickest to dry. Tacky glue proved to be the thickest material that would hold the pin upright, however it took 30 minutes to dry and was not adhered to the pin. We tried acrylic glue, however the dry time was the longest, it was the thickest and easiest to stand up a pin in, yet it was hard to get into our drill hole and do cleanly. The answer was for us to use Tacky glue. This was a long arduous process that we worked through. After Adam and Cody’s layer was finished the idea was presented to heat the pins and melt them into the acrylic. This was the best option. As the remaining meshes were made, less problems arose with the melting process. The threading is all that was remaining. And that went smoothly.

REVIEW MIDTERM PRESENTATION

Overall Analysis of Part I:

REVIEWER’S COMMENTS

Mesh Depth There is evidence of in depth index analysis, but a failure to translate much of that information into the resulting meshed geospatial information layer.

Darrin Griechen We were telling and not showing. Too long spent on each slide. Groups of images not clear for graphics. Diagrams of design criteria would be helpful.

Graphics While graphics were for the most part consistent there were several failures including the black backgrounds and rainbow colored diagrams which reflects a failure to communicate clearly as a team for consistency and quality.

Steve Austin Mapping is a way to represent data geographically how you want it to be seen.

Connection of Information Context was not shown in some instances. Transition from Makoko to Island not well detailed in presentation.

60

John Abell How can you refine your presentation without restarting: Puposcuity would help, showing evidence and then how you reached it. Since you used grasshopper show how you got what you did. Use of hierarchy could be better. Show your insights. Don’t leverage the presentation beyond the data. Show what is unique and what you are building on. Discuss how this is innovative. Discuss the difference between how you map different types of information.

ASSESSMENT OF CURRENT CONDITIONS

1 ACCESS TO WATER Through our analysis we determined what seemed to be the model for this regions settlement expansion and further on attempt to propose a hybrid that builds on this expansion in a culturally relevant way, considering people’s experience, and in an optimize way, considering inhabitant’s tendencies. We describe the current settlement method as the bottom up expansion of a mostly un-selfconscious society. This means it is primarily not well thought out but based on a set of a few definable rules. We measured the current condition of each of our three observed primary factors and for optimization used the average of each category as a limit instead of an average so that each image 1 condition will be significantly improved in our proposed hybrid network for expansion.

INTRODUCTION ASSESSMENT OF CURRENT CONDITIONS

2 ACCESS TO PATHS

3 CONNECTIVITY

Access to paths was assessed to determine the average distance to paths per area and per construction type in each area. This allowed us to both make culturally relevant moves for zoning as well as have a value for desired accessibility as a parameter. Connectivity While we have the resources for measuring connectivity methodically using a grasshopper definition from Configurbanist we have yet to perform this assessment. Rather with the time available we resorted to a quicker method where we simply based connectivity based on shortest paths and on balanced block placement for optimized access and direct routes. 1 mile

RULES ACCESS TO WATER

From our analysis we decided to constrain development to within 500ft of water. We can increase access to more area by adding an inlet(s).

TENDENCY 70% within 500ft 80% within 600ft 87% within 700ft Tend to expand along waterfront

RULE DEFINITION Growth should be planned to have buildings within 500ft of water. Canals should utilize existing water flow paths connecting standing water to shore or be based on 500ft rule. image 1 Distance to water image 2 Inlets increase the perimeter shore line and allow more buildings to be near water

ACCESS TO PATHS

This tendency a basic characteristic of settlement in general and is still a determining factor in this situation.

TENDENCY Major Paths seem to be formed near the shortest path between clusters and important points. New Buildings tend to be build along these paths near existing buildings.

DESIGN OPTIMIZATION COMPLETED BALANCED NETWORK

The dashed blue lines indicate proposed inlets to increase accessibility to water and form a central hub as a market center for the island. The inlets would be built about 40ft wide with maximum 100ft width and would be located along existing low spots where water pooling and flooding is already a problem.

DESIGN OPTIMIZATION SITE SELECTION RATIONAL

Based on previous analysis and from reading Frei Otto’s book Occupying and Connecting the tendency is for expansion to occur along major routes and for crossings to be centers of new emerging nodes. With an inlet allowing access to water this central hub becomes a focal point of the island.

PROTOTYPING INTRODUCTION

At this point we have followed an intervention strategy to subdivide and selectively alter the landscape based on a hybrid between rules we derived from observing the adaptive tendencies and optimization by means of technology. In this selectively altered region we selected an area that has a variety of situations so we can show a how a solution for the problems that arise from a bottom up expansion are better with zoning. At the end of this we propose an architectural typology that meets the intent of our larger scale intervention in being contextually relevant, of local construction type, and alleviates known problems.

Our logic in deciding locations and densities of buildings was based on attractors which we categorized as strong, medium, and weak attractors. Strong attractors include intersections of major roads, and major roads along the waterfront. Medium attractors included the waterfront and intersection major and minor roads. Weak attractors were the minor roads and intersections of two minor roads.

This is a diagram describing our process of following a pattern of settlement based on tendencies we observed in the bottom up expansion while in this case there was a prior balanced network established that was then populated instead of the two occurring simultaneously. It is not a precise description of exact moves the people would make and feel accustomed to but based on an algorithmic definition of how this population expands.

PROPOSED MODIFICATIONS We are proposing a few alternative strategies of construction that are still within the typology found on the island so it is familiar and able to be continued. The double layder of finish one interior and one exterior is not normally how the informal housing is built. We beleive the structures will last longer, be more inviting with an interior finish, and it provides a layer of shading and then a thermal break.

ARCHITECTURAL PROTOTYPE DESIGN By creating a protruding main dock with direct access to the main path the population has a direct access to trade and transport goods. The market structure is like a waterfront display for quick and easy trading while it has connection to the community and to the main routes and secondary routes.

MODEL Explanation

As a display model for our proposal we decided to represent the design as we did in our design at various scales and levels of detail. Since the neighborhood and buildings are simple massings we left them as such in the model and used plexiglass for the buildings that were outside of the focus area. The plexiglass is trasparent as the buildings are currently non existent and they are the same material as the base as they are peripheral. We then used mdf that was sanded and spray painted to represent the where we were proposing an architectural prototype be designed. Challenges we faced included dealing with creating an accurate cut for the taskboard to fit into the waffle mold. Also to bond the plexiglass we ended up melting them together. Taskboard is also very absorbent so drawing the contours and paths was not as clean as we would have liked.

CONCLUSION

This project suceeds in creating a culturally comforatable, contextually responsive, problem solving intervention. Our primary weak point was an underdeveloped final prototype and diagrams explaining its interaction and design. It is important to understand that there could have been many outcomes that would be successful within the same strategy of intervention but this describes a typological solution to increase connectivity, access to water, and access to paths. We lacked translating the specificity of our analysis phase into the design phase in some areas. In retrospect we would have been more descriptive in our intervention process and incorporate those analyses. Further developement will also include creating better renderings and descriptive diagrams of the process. We have discussed significantly more about the design than we are able to show here which we plan to continue detailing after this semester.
