鹤见川流域范围内城市化区域所占比例为80％，由于对土地的更新利用，洪水径流量增加。受上述因素影响，当前河道整治规划的修订工作变得十分迫切。采用诸如开辟当地蓄水区之类的非工程措施，使该流域摆脱经常性的洪水侵害。在开发流域内的蓄洪滞洪效用，鼓励增大地方结合现有防洪的有利条件合理使用土地方面作了诸多努力。
The area of urbanization in the Tsurumi River Basin accounts for 80% of the total. Due to the renewed use of the land, flood runoff has increased. Affected by the above factors, the current revision of river regulation planning becomes very urgent. Non-engineering measures, such as the opening up of local water storage areas, are used to free the basin from recurring floods. Many efforts have been made to develop the utility of flood storage and detention and to encourage more land to be used rationally in combination with the favorable conditions of existing flood control.
