Summary:

Due to the fact that the Expropriation Law numbered 2942 is insufficient in practice

and there is no related regulation in Turkey, easement expropriation is implemented by the

Supreme Court decisions. It is difficult to keep track of these decisions made for each new

situation, and this process requires time and labor. Also, the factors affecting property value

and their degrees of effect are not clear. Since every expert calculates the easement price

according to the criteria s/he chooses, grievances occur.

In this study, a standard effect-value model which determines the easement cost given

to the property owner due to High Voltage Transmission Lines (HVTL) has been developed.

Factors defined in the model were determined as a result of; the literature review, interviews

with local and foreign real estate appraisers, national and international surveys, Supreme

Court decisions and expert reports, and the evaluations based on judges and lawyers. The

weights of these factors were calculated using the Analytical Hierarchy Process (AHP). The

model was created by integrating weight values. The interface software of the model was

made using Node.js, Electron, TypeScript, React, Ant Design and Webpack. The model was

tested with sixty expert reports collected from various provinces. The rate of error in expert

reports was found to be at least 0.38% and at most 84.98%.

This thesis is the first study examining the effect of HVTL on property value and

presenting an effect-value model to determine the easement price objectively and

simultaneously in Turkey.
