Abstract
The minimization of life cycle cost is important subject of social infrastructure management. The life extension by preventive maintenance is generally carried out. In population decline ares, it is not necessary proper measures. The life extension lead to renewal of facilities with smaller scale which adapt to decreased population. In contrast it means to continue to use current excessively large facilities which require large maintenance cost. On top of that, per capita cost becomes high due to population decline as renwal investment is postponed. These issues were examined through a case study.
