The rapid economic growth has been accompanied by the phenomenon of urban concentration of population, which has drawn external expansion to develop the suburbs to cover such phenomena. Cities have been faced with many number of middle-class residents who moved to the new suburb areas from the existing urban areas to the new suburb areas, on the other hand the proportion of low-income and aged people who still remained in the area with low economic power has been relatively increased, which finally resulted in a slumming area with having occurred various crimes as well as having become the housing and living environment obsolete. In order to improve the slum areas, urban maintenance projects such as redevelopment and reconstruction were carried out, but the those were only focused on improvement of the physical environment that did not reflect the characteristics of the resident area, which has been destroyed the history and locality of the region.
As an alternative to solve the problems of existing urban maintenance projects, urban regeneration projects, which is revitalizing cities by taking into consideration not only the physical environment but also the economic, social and cultural environment, have emerged. It is the way of improving and managing the aging living environment with gradually improving the environment and restoring the local community that runs by residents themselves.
This study is compared and analyzed residents'' awareness toward the alley environment in the area where the alley garden was constructed or it was not by targeting the residents'' area of Bisan 2/3-dong which has been evaluated as a success area of the urban regeneration project by creating alley gardens led by the residents. For the purpose of this, a survey has been conducted and the improvement plan was proposed according to the result.
If we look at the current status of Bisan 2/3-dong first, there are eleven Alley Gardens with planted herbaceous flowers and flower pots provided by individuals along the alleyways including so-called ''The First Alleyway of the Garden'' that was the origin of alley garden in that area and there are 22 Themed Gardens more including a Watermill Garden, an Eve Garden, and a Tunnel Garden using illegal garbage dumping place and squatting space. In addition, flower-shaped lighting lamps and lanterns made by residents have been installed as part of the project for making ''Happy NALMAEGOL'' as well as improvement in floor pavement, fence maintenance and murals have been made up. In case of non-constructed area, franchise-featured streets are in the progress of construction focusing on Seobu local market.
As a result of analyzing the residents'' awareness about the alley environment, there was no significant difference in the composition of the respondents such as the sex ratio, as a result of examining the residents'' awareness about the composition of the alley garden for the 125 respondents from the constructed area, 96% of them showed a high agreement for the creation of alley garden, and the reason why they agreed such was the beautiful and pleasant alley was. It was found that providing flower pots and individual gardening were the most common methods of participation.
As a result of analyzing the importance of the components of the alley environment, the importance of safety related items such as lighting facilities, CCTV, floor pavement, and vacant house maintenance was highly evaluated in both the constructed and non-constructed area. There was no significant difference in importance between the two areas.
Satisfaction with the alley environment was found to be high in the amount and types of lighting facilities and herbaceous flowers in the constructed area, while satisfaction with handicraft workshop and resting facilities and public parking lot was low.
On the other hand, the non-constructed area was evaluated as a lower rating than that of constructed area in all items, and the overall satisfaction from those who were in the constructed area was also higher than that in non-constructed areas. As a result of analyzing the settlement and the sense of community according to the alley environment, it was analyzed that the residents of the constructed area, who had positive minds on alley environment with the alley garden, gave higher evaluation than that of residents in non-constructed area.
Based on the above results, this study is to propose as follows; The first is construction of resting facilities and parking spaces utilizing vacant houses; The second is to secure the safety in the alleyways; The third, it is necessary to improve the overall environment of the alleys in the non-constructed area as well as constructing the alley garden using like herbaceous flowers.
This study has its meaning to have suggested the improvement plan of the alley environment by analyzing the current status of the alleys and the residents'' awareness in the both residential areas - garden constructed area and non garden constructed area - of Bisan 2/3-dong. In addition, it can be also judged as a basic data for alley garden construction in other areas.
