Moizari River, a tributary stream of Izari River in Eniwa City, used to be a rich creek where salmon spawned. The river improvement construction was done from the 1950s straightening the river course and using the triple-phase method to keep the nearby farms away from floods, but the succeeding rapid city development lowered the flood control safety level. In 1986 the river improvement was restarted, which was certified in 1990 as the second “Hometown river model project” in Hokkaido. Various nature-based methods were introduced with the theme of “waterfront with no makeup,” integrating the river with nature and greenery. River-walk has also been prepared as a part of human-nature symbiotic city development.
