HSR building restriction area inquiries system are based on "Guidelines for Non-urban Land Use Category Change" by Ministry of Interior.
According to the distance from inquired land location to HSR routes, inquired results can be divided into 3 categories. Official inquiry and reply processes are as follows:
1. If the inquired land is not located within the administrative areas where HSR passes by, reply should indicate that such inquiry can be omitted due to land is located in the administrative areas listed in Appendix 1/ "Conditional Development Regions"/ Note 7 of the Guidelines. The result is replied via post.
2. If the inquired land is located within the administrative areas where HSR passes by, further query is required. By registering road section and land no. of the inquired land on "Cadastral Data Network System, Ministry of Interior", the land location can be displayed (with relative position to HSR). If the distance between land location and HSR exceeds 60m, the location is not within the HSR building restriction range.
3. If the inquired land is located within the administrative areas where HSR passes by, further query is required. After registering on "Cadastral Data Network System, Ministry of Interior" and cannot directly determine whether the distance exceeds 60m, the next step is overlapping the cadastral map of the applicant and the HSR building restriction cadastral map. The map-overlapping result is then replied to applicant via post.
This action in advance can not only reduce risks of possible construction safety issues that might occur but can also consider potential impacts beforehand for constructions that are near HSR routes. BOHSR will play the role as HSR competent authority and continue to implement such inquiry and reply procedures to enhance prevention measures and maintain HSR structural and operational safety.
