Do yo mean if you have land in Kajiado which you intend to subdivide? Any land in Kenya intended for subdivision is fisrst studied by the County planner who determines the width of the roads. If near a busy highway, he/she might ask for it to be 20,25 or 30m wide. If on a small feeder road, it can be 9, 12 or 15 m wide. Lands subdivided previously when there were no planners in govt offices resulted into the 5m wide roads currently seen in rongai and ngong areas.
