There is urgent need for uniform, integrated legislation to deal with planning. There is indeed little in the planning legislation that is comprehensive, and, much is left to the operator's discretion.

In addition to these legal aspects, Nairobi has to contend with the following problems which arise from failure of the planning function:

1. Development has been disorderly, which accounts for the unplanned, haphazard distribution of human settlements with their incongruous mixture of activities.
2. Too much employment is concentrated in the City centre and the industrial area, out of all proportion to other parts of the city. This has grave strategic implications.
3. Unplanned and un-serviced human settlements have expanded enormously. About 55 percent of Nairobi's population now lives in such areas.
4. Congestion in the City Centre and the industrial area has created gigantic problems of traffic congestion and environmental pollution.
