This study proposed the future directions of waterside maintenance through residents’ awareness of the waterside as a residential environment based on their evaluations of apartment house formed in the Tokyo Waterfront Area, where the population has sharply increased with rapid residentialization. Then, this study drew the elements of the improvement of the waterside based on the accessibility to the waterside through the factors enhancing satisfaction with it. In addition, as the maintenance of the waterside based on ‘Waterside Satisfaction, ’ this study verified the validity of the elements of improvement drawn for the enhancement of accessibility to the waterside.
1) Awareness of waterside as a residential environment
In all generations, concerning the waterside as a residential environment, ‘Importance Evaluation before Residence’ was higher than the average while ‘Performance Evaluation after Residence’ was lower than that. Through this, it was found that the waterside would be the element preferentially needing improvement of ‘Residential Environment Elements’ commonly among all the generations.
2) Factors enhancing satisfaction with waterside
It was found that the factors enhancing ‘Waterside Satisfaction’ differ depending on the generations. In Young Generation, the increase in ‘Visit Count’ was related to ‘Waterside Satisfaction.’ In Middle Generation, the decrease of ‘Time Distance’ was related to ‘Waterside Satisfaction.’ In Old Generation, the decrease of ‘Time Distance’ and the increase in ‘Visit Count’ were related to ‘Waterside Satisfaction.’
3) Maintenance of Waterside base on ‘Waterside Satisfaction’
As for the maintenance of Waterside based on ‘Waterside Satisfaction, ’ this study conducted a survey on the validity of the enhancement of accessibility to the waterside with the opening of ‘Walk-through’ that shortens ‘Time Distance’ to increase ‘Waterside Satisfaction’ and the promotion of ‘Waterside-open’ that increases ‘Visit Count.’ As a result, it was found that the opening of ‘Walk-through’ and the increase in ‘Waterside-open’ had validity for enhancing the accessibility to the waterside. It turned out that in all target areas, the increase in the average Int.V with both the opening of ‘Walk-through’ and the increase in ‘Waterside-open’ was higher than the increase in the average Int.V with the opening of ‘Walk-through’ and the increase in the average Int.V with the promotion of ‘Waterside-open.’
Conducted the following discussions based on the above analysis results.
In all households living in apartment houses in the Tokyo Waterfront Area, the waterside as a residential environment is one of the elements preferentially needing improvement, and maintenance to enhance satisfaction with the waterside is required. In addition, in the maintenance of the residential environment to enhance ‘Waterside Satisfaction, ’ since Young Generation and Old Generation are related to the increase in ‘Visit Count, ’ it is effective to stimulate the promotion of the chance to visit the waterside by ‘Waterside-open’ that places a usable waterside near a residential area. Also, since Middle Generation and Old Generation are related to the reduction of ‘Time Distance, ’ an improvement that shortens the travel range to the waterside by ‘Walk-through’ is effective. Also, through an analysis based on the Space Syntax theory, it was found that ‘Walk-through’ that shortens ‘Time Distance’ to enhance ‘Waterside Satisfaction’ and ‘Waterside-open’ that increases ‘Visit Count’ enhances the accessibility to the waterside. Especially, the simultaneous maintenance of the opening of ‘Walk-through’ and the promotion of ‘Waterside-open’ would enhance the accessibility to the waterside from all target areas.
