1989 Volume 44 Issue 1 Pages 1-16


The writer investigated the dissolving process of a flood prevention cooperative in frequently inundated area from the viewpoint of flood prevention imposition system. The author took the case of the Tsurumi River Flood Prevention Cooperative. She analyzed and considered its flood prevention expense. The consequences are as follows: 1. In the imposition system, the dues were collected from many objects which were classified into three ranks according to their flood risk. However the objects were integrated into two kinds and the rate became uniform, because flood risk dwindled on account of river improvement works. 2. Many people migrated to the river basin considered the dues of the cooperative as the dual payment of tax and most of them did not pay the dues. Since the due payer became less year by year especially after 1965, revenue of the cooperative became to depend highly on subsidies from local governments. 3. Major expenditure of the cooperative changed from managing cost to guarding expenses and reserve funds, because urbanization caused the increase in floods. Consequently the cooperative became unable to maintain itself financially and was dissolved. It was reorganized as "the Flood Prevention Association" run by subsidy from the municipality. The factors behind these phenomena were rapid urbanization, river improvement works and change of dwellers sense on flood prevention.
