A Study on the Possibilities and Institutional Burdens of the Use of Underground Space as a Substitute of Land Surface

1. CONTENTS (1) RESEARCH OBECTIVES A Study on the Possibilities and Institutional Burdens of the Use of Underground Space as a Substitute of Land Surface aims to provide future directions for an institutional improvement and alternatives for executive policies in terms of vitalizing underground development in multi-dimensional and network formation. (2) RESEARCH METHOD Quasi-experimental analysis: literature review and comparison with various criteria related to the right of land ownership and use right both of the national and international perspectives. (3) RESEARCH RESULTS Examinations of the various criteria related to the right of land ownership and use right both of the national and international show that foreign nations, such as Germany, Switzerland, United States of America, have run an unique spatial limits of the right of land ownership. That is, these nations admit only a limited right of land ownership based on the existence of economic feasibility produced from the underground due to the possession of the land, while our nation has no clear criteria for these matters. In addition, examinations of the right of underground development and used in our nation show that there exist some theoretical conflict over the dividen easement in underground development. 2. RESULTS Based on the results of the examinations of the study we propose three different institutional improvement directions. First, we concluded that it is necessary to coordinate existing regulations related to the spatial limits of the right of ownership in terms of the use of underground space. Second, it is necessary to mediate existing regulations of the limit of depth to land for providing appropriate compensations and encouraging underground development. Finally, it is necessary to mediate current calculation method and implementation process of the multi-dimensional impediment rate from the comprehensive planing perspectives. 3.
