Water Act Article 82

Land lying within the line of a waterway management plan or the scope of land line may be requisitioned by the government according to law after the authority-in-charge submits its plan to the superior authority for approval and public announcement. As to such land not requisitioned, the authority-in-charge may restrict its use for the purpose of flood control.The land lying within the line of a waterway management plan or the scope of land line, when promulgated, shall be subject to a regular and comprehensive review by the authority-in-charge. The authority-in-charge, however, may conduct timely revision or amendments in case there is a drastic change to the waterway caused by natural disaster.In case that private land or existing dike land becomes unusable because they have been announced by the authority-in-charge, based on paragraph 1 above, as falling within the line of a waterway management plan or the scope of land line for installing flood-control facilities or for other waterway management projects such as river cutoff or expansion of river cross sections, the authority-in-charge may requisition the land if necessary.Private land located in river areas which has become unusable due to reasons specified in the preceding paragraph may apply for transfer of plot ratio if the land is located within the scope of an urban plan already approved by the authority-in-charge but has not yet been requisitioned. In this case the transfer of plot ratio should be administered in accordance with the rules specified in Article 83-1, paragraph 2 of the Urban Planning Act, including the methods to determine the transferable plot ratio, the location of the receiving land base, the maximum plot ratio for the receiving land base, the method of transfer and administrative procedures, etc.The formula for the plot ratio transfer shall be established collaboratively by the Ministry of Interior Affairs and the Ministry of Economic Affairs.
