ABSTRACT The need for enhancing utilization of a public transport interchange has come into realization as a means of making public transport interchanges more user oriented than purpose oriented. This realization is geared towards addressing the needs of the end user of public transport interchanges with regard to human scale, landscape elements, landscape quality, mobility or connectivity and the environmental quality of public transport interchanges. The syokimau transport interchange is currently designed to provide basic function of facilitating movement, boarding and alighting in a railway terminal. Therefore providing great potential for landscape oriented interventions. The proposed syokimau transport interchange is deemed a vital solution to the status quo as regards utilization at the interchange. As such, this report seeks to define the problem and further the practicability of the proposed solution in terms of economic viability, constructability and social-cultural viability. The author was inspired by the need to uplift the diminished quality of utilization of public transport interchanges. The study thus investigated the prevailing elements of landscape design and how they relate to utilization of space by the end users of a public transport interchange. In chapter three, this report will seek to address the environmental impacts anticipated during and after the execution of the project. Case study analysis will be dealt with in the fourth chapter and finally the guiding design philosophy which will be highlighted by supporting concepts.

1.1.0 Introduction. Normally, public transport interchanges in Kenya have been designed concentrating on the basic concepts of civil design that are aimed at delivering the basic functions of transport interchanges, which is facilitating movement. This downplays other vital roles that a public transport interchange ought to perform in order to yield satisfactory utilization trends and requirements to its end user, for instance the environmental quality and aesthetics. Often time, landscape design comes as an afterthought since focus is majorly geared towards design of indoor interchange building, vehicular circulation and consequently this result in disregarding pedestrian connectivity and pedestrian experience within the interchange. Also social activities at the interchange are also neglected. It is therefore imperative to enhance utilization of public transport interchanges, here envisaged to be achieved through landscape design. This indeed will serve to be a welcoming gesture to every end user of the interchange. Introducing landscape elements will provide necessary convenience and enhance user experience at the interchange, while at the same time having other social joints for instance eateries and trade areas will ensure multiplicity in utilization of public transport interchanges.

1.2.0 Problem statement. Problems faced in most urban areas around the world are not unique to any. They are mostly as a result of the city’s morphology. Efficient operation of any urban transport interchange is central to development of any city. There is a widespread reliance on vehicles for public transport, but even more need for rail transport to providing mobility within an urban area. However, most transport interchanges have been constrained to the basic use of movement from point A to point B, thus being underutilized. The Syokimau Transport interchange is one of the stations developed under the Nairobi Commuter rail project. Located in a growing middle income residential area, the station serves over 2500 users each day (nation.co.ke); however the station 3


Re-thinking Public Transport Interchanges

Syokimau Public Transport Interchange

currently is underutilized due to non-provision of complementally activities. The station is only used by commuters to catch the train to and from their work and does not serve the surrounding neighborhood. A transport interchange is a complex system of interrelated functions requiring constant movement of people, goods and vehicles (GRAVA, S. 2003.The Syokimau transport interchange is located in the outskirts of Nairobi, adjacent to the Jomo Kenyatta international airport (JKIA). Failure to address utilization of the transport interchanges will result to detrimental effects on city’s environment: increased air and noise pollution due to the increased delays at the station, severe traffic congestion, which not only causes delays, but also increased fumes and noise. Traffic congestion also increases health risks of road users and residents. Currently one of the efforts that have been made in related studies looks at an integrated terminal design approach to the specific means of transport and conveyance of users from one point to another with no interrelation of the spaces. Therefore, this study will look at how to effectively and efficiently address an integrated transport hub to the problem through landscape design by creating connectivity and interrelation of various spaces at the Syokimau transport interchange. A transport interchange is an urban open space. It is important to take cognizance of this, and consequently address it as such, and therefore this project seeks to increase the level of use. This will be envisaged to be expressed through landscape design. The careful arrangement and provisions of landscape elements will enhance its correct use, consequently creating the facilities dignity. The landscape elements will not only resolve spatial and civil design conflicts but also will enhance aesthetics and aid in mitigation of environmental problems.

1.5.0 Project Justification. A public transport interchange is an urban open space and therefore it would be very important to take cognizance of this and consequently address it as such. This is currently envisaged to be expressed through landscape design. The careful provision of landscape elements will enhance its utilization. Use of landscape elements will result into enhanced user experience. Planting as an element of the landscape will aid in mitigation of environmental problems such as pollution, excessive winds, and high temperatures in addition to enhancing aesthetics. Pedestrian access and circulation is not adequate at the syokimau transport interchange and this discourages users to even momentarily stop at the interchange for other purposes such as recreation and business activities and in this result to underutilization. The proposed syokimau transport interchange will deliver a fully integrated circulation system with a special consideration to the pedestrian as a user and also as a commuter. The result will be reflected with an increase in utilization. The aspect of landscape design to solve underutilization at syokimau transport interchange comes at a time when Kenya is envisioning 2030 development goals and therefore this means that this project proposal will be a part and parcel of the expected deliverables come 2030. Once implemented, the proposed interchange will also generate revenue from activities at the interchange.

1.6.0 Project Viability. 1.6.1 Economic Viability. The development is projected to be sourced mainly from The Kenya Railways Corporation and the Government of Kenya through the ministry of transport and infrastructure and investment partners to the project.

7


Re-thinking Public Transport Interchanges

Syokimau Public Transport Interchange

Thesis Programming 2016

Revenue is envisaged to be sourced from charges to parking facilities, social activities such as sports and recreation, advertisements and renting of trading facilities thereby reducing the cost of external funding. 1.6.2 Cultural Viability. The project seeks to run parallel with the faced paced livelihoods of the urbanities. This will be achieved through applying the principle of multi-use such that the interchange becomes sustainable one stop shop. The project also seeks to address social spaces provision. Currently, there are temporary social activities that include sports and recreation at syokimau transport interchange that are utilized by mostly the locals around the interchange. This project will result to expansion of these social spaces into elaborate and functional spaces that can be appreciated by the end users. The proposed syokimau transport interchange is a development that will attract higher population and therefore comes in handy with urban culture. This will be envisaged through promoting spaces that promotes such culture, for instance space for graffiti and sculptures and sports such as skating.

1.7.0. Project Constructability. 1.7.1. Material The choice of material will be informed by the effect the designer seeks to achieve. This project will seek to address contemporary trends in the urban setting and therefore adopting materials that express the notion of the future as well as addressing environmental sustainability through use of recycling, re-using, and reducing negative environmental impacts. The choice of material will also be affected by the availability of the materials. Some proposed materials will include but not limited to; brick, slate, steel, concrete, wood, glass and PVC, scrap metal and other recycled materials.

Planting material will also be selected to suit function for instance aiding in mitigation of environmental problems such as heat through shading, wind and noise control, storm water, given that syokimau transport interchange lies in a hot and dry climate. Some of the plant plants to be used for this project include Mellaleuca linarifolia, andAcacia xanthophloea. 1.7.2. Technology .Existing workforce will be sourced from the relevant authorities that include the ministry of transport and infrastructure and the Nairobi city county. Sustainable locally sourced materials are going to be adopted for this project.The craftsmanship adopted for the project is envisaged to be easily sourced from within the local Kenyan context. 1.7.3 Professional Skill. The project will be overseen by a committee of professionals comprised of Project managers, Landscape Architects, Architects, Engineers, Quantity surveyors, Construction managers among others who will be deemed necessary. 1.7.4 Labor. The project will source its labor from the surrounding syokimau community. This will be in line with empowering communities through employment especially the youth. This will also see that the project is in line with vision 2030 which aims to improve the quality of life to the Kenyan citizen.

1.8.0. Project Sustainability. 1.8.1 Environmental Sustainability. It is likely that the proposed syokimau transport interchange will majorly be composed by hard landscape, therefore creating the opportunity for rain water harvesting which will be used for maintenance of the landscape, water features, and other activities that require water. Rain water will also be harvested from roofs and canopies. 9

Syokimau Public Transport Interchange

Thesis Programming 2016

The proposed syokimau transport interchange will adopt renewable sources of energy so as reduce expenditure thus ensuring sustainable development. The renewable source of energy will include tapping of solar energy since the area experiences long hours of the day with high temperatures. The project will also exploit wind energy to supplement other sources of energy. Garbage collection and recycling regime is also advised in order to achieve environmental sustainability. Recycled materials will be used for purposes such as construction or public art. 1.8.2 Social cultural sustainability. The inclusion of social spaces within the interchange will ensure utilization through human interaction and therefore opportunity for revenue generation. Sporting activities such as skating, market places and eateries will generate revenue thus ensuring economic sustainability. The interchange as a public open space will serve to provide a platform for healthy urban culture through art and conveniences provided within it.

Where Ct = net cash inflow during the period t Co = total initial investment costs r = discount rate, and t = number of time periods A positive net present value indicates that the projected earnings generated by a project or investment (present) exceeds the anticipated costs (present). Generally, an investment with a positive NPV will be a profitable one and one with a negative NPV will result in a net loss. This concept is the basis for the Net Present Value Rule, which dictates that the only investments that should be made are those with positive NPV values. Year

The winning contractor will be invited by the client and their consequent acceptance will warrant the signing of the contract and reaching to an agreement. This will be the precursor to the handing over of the site to the contractor.

The estimated time for the pre-contract period is 30 weeks. 2.9.2 Post Contract Stage This will be the process of actualizing the project on site. The contractor will commence construction after occupying the site. He will complete the works as stipulated in the contract documents to the satisfaction of the Landscape Architect who will be the lead consultant. It is expected the contractor will carry the work regularly and diligently. The post contract management will be consultants, team duty. The estimated time period for the post contract per is 46 weeks, with an additional 13 weeks for the Defects Liability Period.

3.0 ENVIRONMENTAL IMPACT ASSESSMENT. This section deals with impact assessment (EIA), the definition of terms, importance of EIA ,key features of EIA, EIA as a planning tool ,EIA process, EIA Methods ,environmental guidelines and standards ,assessment of impact of the proposed project and checklist.

41


3.1.0 Introduction. The goal of EIA is consistent with the overall goal of the Ministry of Transport and Infrastructure and Kenya’s Vision 2030. Environmental Impact Assessment is a tool for environmental conservation and has been identified as a key component in new project implementation. According to section 58 of the Environ mental Management and Coordination Act (EMCA) No.8 of 1999 second schedule 9 (1), and Environmental (Impact Assessment and Audit) regulation, 2003, new projects must undergo Environmental Impact Assessment. The Report of the same must be submitted to National Environment Management Authority (NEMA) for approval and issuance of relevant certificates. This was necessary as many forms of developmental activities cause damage to the environment. The EIA for the Syokimau Transport Interchange will be conducted in accordance with the Environmental Management and Coordination Act (EMCA) of 1999. The methodology adopted for this includes checklists, interviews with users of site and critical observations as well. For the purposes of this project, the EIA process will seek to; •

Predict environmental consequences of the Proposed Syokimau Transport Interchange

Identify negative and positive impacts of the project.

Plan for measures to mitigate adverse effects and maximize on the benefits of the project.

Inform planners, decision makers and stakeholders on the effects of the development.

3.1.1 Definition of terms. Environment: Refers to the physical factors of the surroundings of human beings including land, water, atmosphere, climate, sound, odor, taste, the biological factors of animals and plants and the social factor of aesthetics and includes both the natural and the built environment EMCA, (1999).


Re-thinking Public Transport Interchanges

Syokimau Public Transport Interchange

Thesis Programming 2016

Impact: Refers to any change in the physical-chemical, biological cultural and socio-economic environmental systems that can be attributed to human activities to human activities relative to alternatives under study for meeting a project need Canter, (1977).

Assessment: It involves the use of systematic and interdisciplinary approaches, methods and procedures to ensure presently quantified environmental amenities and values are given appropriate considerations in decision making along with economic and technical considerations Canter, (1977).

Environmental impact assessment: means a systematic examination conducted to determine whether or not a program, activity or project will have any adverse impacts on the environment EMCA, (1999).

Methodology: This involves the careful study of the proposed project site, and the possible impact s of the project as observe from previous similar projects. Impact methodologies provide an organized approach for predicting and assessing the impacts of a certain project. The methodology should be relevant to ensure the environment is protected and little or no negative impact on the environment is experienced now or in the future.

3.1.2 Importance of EIA 1. Carry out an investigation on environmental baseline status of the site. 2. Present information on impact alternatives 3. Present the results of EIA in any way that it can guide in informed decision making during the design process. 4. Present mitigation measures for the environmental baseline status of the site area. 5. Provide a description of the activities to take place at the proposed site.

3.2.0 Steps in the EIA Process. There a six basic steps in the process of conducting an Environmental Impact Assessment. This process will also guide the EIA for the proposed Syokimau transport interchange.. 1. Environmental screening 2. Scoping and preparation of the terms of reference (TOR) for conducting EIA and other related studies. 3. Preparation of an EIA report and project appraisal. 4. Implementation of the project 5. Monitoring and evaluation.

3.3.0 Project Background. 3.3.1 Scope of the Study. The scope of the assessment covered in this study involved impacts that directly or indirectly associate with construction and operations of the proposed Syokimau transport interchange. This include circulation systems, drainage systems, social activities such as sports and recreational activities, enhancement of parking facilities, shade structures, signage and other associated structures, planting zones with planting buffers and open grounds for trade activities and exhibitions. The assessments of the aforementioned works will result to a comprehensive Environmental Impact Assessment Study report. 3.3.2 Objective of the study. The objective of this study is to establish the environmental impacts of the proposed syokimau transport interchange.

4.0 DESIGN PHILOSOPHY AND CONCEPTS

66


Re-thinking Public Transport Interchanges

Syokimau Public Transport Interchange

Thesis Programming 2016

4.1.0 The Urban Radial Melt The Syokimau transport interchange is envisioned to be a transport hub that attracts users for more than just transportation. It shall also be a hub that serves the neighborhood, therefore making it a converging point of users and a diverging point for services to the neighborhood. Legend Users Activities

4.2.0 Concepts The urban radial melt is supported by the following concepts. 4.2.1 Placemaking Placemaking is a design and planning concept that capitalizes on the local community’s assets, inspiration, and potential, ultimately creating good public spaces that promote people’s health, happiness, and wellbeing. Placemaking stresses the value of what already exists in the neighborhood, ranging from shops and services to community expertise. This strategy for designing urban spaces is strongly influenced by residents.

Figure 9. Placemaking

68


Re-thinking Public Transport Interchanges

Syokimau Public Transport Interchange

Results of such planning are usually more functional, contextual and inclusive. Some physical attributes of spaces that characterize successful places include human scaled amenities and clever uses of vegetation. These spaces tend to generate a greater sense of ownership among the community rather than top-down designs implemented without consultation. 4.2.2 Shared Space. Shared space is a design concept for public spaces that promotes removing the separation between modes of transport in order to create more pedestrian friendly environments. The idea of removing ground markings for traffic, which are painted in the name of safety, seem counter intuitive at first, but the result is more eye contact, slower speeds and heightened awareness.

Figure 10. Concept of the shared space

69


Re-thinking Public Transport Interchanges

Syokimau Public Transport Interchange

Thesis Programming 2016

It will be therefore imperative to create awareness and educate all drivers using the interchange and also to control speed on within the interchange through an integrative design so as to achieve this concept.. The study also shows that the more familiar people are with shared spaces, the more likely they will be in favor of such features in their city. Therefore, the first shared spaces will require considerable work from all parties involved. With an initial success, subsequent shared spaces may come much easier.

4.2.3 Style. Because public spaces such as bus stops affect the daily lives of many, the styles of these elements are important. From survey results, it is shown that most people prefer public spaces that are backdrop-like, that blend in with the surroundings and do not seek attention. The general public likes patterns of conformity and order more than design professionals. These preferences speak to the desire of people for a more integrated travel experience that benefits from the latest advances in design but also has a relatively conservative look that maintains its attractiveness over time. In addition, it is important to not be carried away by over urbanizing spaces, for there are many factors of lower density developments, such as long views, that are conducive towards active transportation. Other principles such as Crime Prevention Trough Environmental Design are also popular in the field of public space design (Alliance Against Crime, 2011; Saraiva & Pinho, 2011).

4.3.0 Other supporting concepts 4.3.1 Planning concept This relate to the hierarchy of organization of activities with the main activity as a transportation interchange where activities such as recreation will serve to enhance the utilization. The design will seek to ensure mobility especially by addressing pedestrian needs. Multiplicity in utilization will also be adopted.

4.3.2 Economic concept The project incorporates income generating activities such as trading sheds, eateries, sports and advertisement boards. 4.3.3 Form concept This will be with regard to creation of legibility and iconic precinct at the interchange. The forms will be in line with a resolved theme to create unity. 4.3.4 Environmental concept The design, through use of more green areas shall strive to mitigate environmental problems. Also sustainable materials shall be used, collection, treatment and re-use of storm water shall be done so as to ensure environmental sustainability.
