Fukuura, Yugawara is the fishing village in Manazuru peninsula. The place has a unique landscape, a lot of stairs, stone retaining walls, narrow alleys and high-density housing. However, due to falling birthrate and aging in this area, depopulation is progressing.
As method, we define stairs and retaining walls as a part of elements on the street. Furthermore, the fishing village on the mortar-shaped slope is selected as a research subject. In such topography, redevelopment is extremely difficult due to complex alleys and the form of topography. To study the relationships between components and the street structure, it is considered important for utilization of the existing street.
The purpose of this study is to clarify (1) the characteristic of shape of stairs and retaining walls by actual measurement survey. Then, it investigates (2) “the route from the road to a house” and “the network of flow line” on the mortar-shaped slope.
Results are summarized in the following statements.
1）a. The dimension of width of stairs is independent from difference in topography and distribution.
b. In the west side slope and the east side, there is an evident difference of the shape of the retaining walls.
2）a. Fukuura does not have a network of flow line using the whole topography of the mortar-shaped slope because the flow line on the west side slope and the east side are independent.
b. The flow line of invading two-wheeled vehicle that connect between the road and a house has an important role for the semilattice network of flow line on the east side slope.
In conclusion, this research suggests possibility of “the flow line of invading two-wheeled vehicle” as a method of street utilization.
