OUTLINE OF PRESENTATION Introduction Background of the study Problem statement Objectives of the study Area of studyMethodology Data and their sources Materials and their sources Overview of methodologyResults and interpretationConclusions and recommendations
IntroductionBackground of the study
a road- a long narrow stretch with smoothed or paved surface made for travelling by vehicles and carriage between two or more points
A road reserve- a strip of public land between abutting property boundaries specifically gazetted for the provision of public right of way
Encroachment- unlawful entering, gradually and without permission upon the land, property, other possessions or rights of another
Problem statement Many cases of encroachment on
road reserves Increased traffic jams due to reduced
road width Controversy between government
and members of public on issues of encroachment
Encroachment on road reserves interferes with development and maintenance of roads
Objectives of the studyGeneral objective To assess the extent of encroachment
on the road reserve of the study roadSpecific objectives To demonstrate the application of
AutoCAD and GIS in mapping encroachment on road reserves
To develop a road reserve map of the study road
To recommend ways to reduce encroachment on road reserves
Area of study
Area of study(cont’d) Kikuyu-Nderi road is a 4km road found in
Kikuyu Township, Kikuyu constituency which is in Kiambu County.
It starts from Kikuyu town all the way to Sigona near Sigona golf club where it joins Nairobi-Nakuru-Malaba road
It lies within the following graticules: latitudes 0˚22’28.18’’S and 0˚22’36.34’’S longitude 36˚53’53.64’’E and
36˚53’50.05’’E.

conclusionThe following conclusions were made The road reserve of the study road has been
encroached There are sections which are completely
encroached There is road re-alignment whereby the
road has encroached land parcels The most encroached sections are those
with general boundary Sections with fixed boundaries have less
encroachment
Recommendations there is urgent need for action to be
taken on those who have encroached the road reserve
Those affected by road re- alignment to be compensated
All road reserves to be mapped and protected and if possible made available online
Sensitize members of the public about the role of road reserves and the legal implication of encroachment on public land
Update all records dealing with roads such as RIMs and survey plans
