This research aims to analyze the "parklet" and "plaza" generated by the Pavement to Parks Program in U.S. San Francisco and to consider the main point in the case of planning, designing and using a street as a place for people's exchange and stationary. It become clear that the half of streets which parklet and plaza are installed have characterized by concentration of neighborhood shops and have the location which public access is easy to obtained. The design of parklet and plaza has attained pedestrian friendly and desirable amenity for people. And also it is the design as inclusive public space which people can continue to stay without interference mutually. The parklet as public space and the sidewalk seat in front of the cafe is articulated and both parklet and plaza serve as open space which includes people's various activities. In addition, sustainable design here assumes not to maintenance-free and durability of initial condition but to frequent maintenance and repair. It also become clear that the purpose of plaza project is the making people's place on the street and the purpose of parklet project are street beautification and to put the rest space. As for the plaza, the temporary one is built first and then improved in full-scale. And it is the issue that not only a control of the undesirable use such as crime prevention but also a promotion of the desirable use such as an event. As for the parklet, the maintenance issues for each cases, such as a cleaning, a burden of the repairing cost in a hardware, and so forth. It can be summarized in the problem of fund. It is considered that the pavement to parks program create a place of human-centered on the road. Seating space of parklet is designed so that many and unspecified persons may not carry out mutual interference but may continue to stay, and also to be a inclusive humane space on the street. The installer of parklet and plaza has been recognized as a host rather than maintenance administrator. Although maintenance of a parklet is managed by the shops in front, it is not use for commercial. Design and use of parklet and shops are separated. Although the parklet manual shows the guideline of its location criteria and design elements, the its design is diverse, in particular, the part of user interface. It would say that parklet create a public open space on the street in the user's point of view. In parklet and plaza design, priority seems to be given to humane and desirable amenity over the durability that assumes the repair and frequent maintenance. It is thought that this design offers comfortableness. Event use, safety, and aesthetic are contributed to comfort for people, too. The process of temporary plaza improvement promotes sympathy and agreement formation of a local community with verification of their various subjects through its experimental introduction. By trial and error, it enables the design which gives priority to atmosphere or creativity over durability. It is thought that these two points offer the process of both the publicness in a user viewpoint and the people's comfortableness.
