1. STUDENTS’ SUSTAINABILITY SUMMIT – 2008 UNIVERSITY OF REGINA, REGINA - CANADA 11 TH -16 TH MAY 200 The Ecological City Plan; Integrated Concepts For Infrastructure Upgrading In Slum Settlements, The Case For Kibera, Kenya BY: Arch. ALALA N. WILLIS

9. Kibera slums, Nairobi - Kenya

11. An Overview; Kibera is the largest informal settlement in Nairobi and covers approximately 225 hectares and lies along a railway line. It has an estimated population of 500,000 with a density of 2000 per hectare. With 95% of the residents as tenants, the slum lacks a functioning infrastructure network Water supply; Only 11.7% of household have connections to piped water Sanitation, Drainage and Refuse Collection 95% lack adequate infrastructure facilities. Underground sewerage is totally absent. Transport, Access and Energy supply. Kibera lacks designed roads. There are informal footpaths and most earthen roads are too narrow or are blocked by garbage. Land Use Impacts. Land Use governance and design is totally absent. Community facilities for example lack in these slums.

14. Kibera Informal Settlement Existing Conditions, proposed railway lines, link and housing units highlighted The Slum Networking Proposal

15. Major infrastructural systems: Railway line, proposed Southern Bypass and link Road, Ngong River and Nairobi Dam

16. Major natural Drainage systems

17. Figure Ground comparison of Kibera housing clusters, immediate environs and Infrastructural systems

18. Identify key infrastructural system and create plots that can be sold and the income used to improve the infrastructural systems within the slum. Drainage channels to be cleared as well.

19. Introduce green corridors, drainage systems and transportation networks

20. Final Build-out consists of 3-4 storey commercial and residential properties creating a boundary around traditional Kibera housing clusters

21. The Sector Study Approach.

22. Figure ground of existing conditions: The Ngong River restricted the growth of the informal settlement to the south. The Settlement turns it back to the River using it as a dumping ground for solid waste and sewer for gray water

25. Introduce major transportation network, as far as possible following the existing systems.

27. Final Build-out; Expected 3-4 Storey Commercial and residential properties, creating an edge for the housing clusters within the settlements
