Abstract

The future water management needs decentralization of facilities, diversity of technology and integration of management to overcome the waste of financial resources and increase in scale of facilities that occurred from centralized water management. In addition, citizen's environmental awareness and participation is important because all infrastructure installed in the watershed where citizens live should have the function of water management. Therefore, the research was performed by investigating the citizen's recognition about urban environment와 LID application to analyze citizen's perceptions and analyze the feasibility and possibility of LID application. The LID awareness of citizens was about 59%, but only about 46% of citizens agreed on the extension of application. However, after contacting LID photographs and information, 90% of respondents agreed on the application of LID, and 94% of respondents were able to distinguish between grey infrastructure and LID infrastructure. Citizens appeared to have a tendency to recognize green spaces as multi-functional LID infrastructure or green infrastructure. If citizens recognize multi-functional LIDs only as landscapjng area, it will be very difficult to extend the LID on the city areas. Therefore, for the extended application of the LID facilities, it is necessary to use public relations strategy to utilize the results and visual data on the actual effect verification. In addition, as every social infrastructure is formed in watershed where citizens live, it is necessary to plan and manage the infrastructure through governance with citizen participation.

과거 물관리는 하천 중심으로 사업이 진행되면서 단일 기능의 집중형 물관리였다. 미래 물관리는 집중형 관리로 인한 시설의 대규모화를 극복하면서 재정의 낭비를 줄이고 다양한 부가 기능을 유도할 수 있도록 시설의 분산화, 기술의 다양성, 관리의 통합화가 필요하다. 또한 시민이 살고 있는 유역에 설치되는 모든 사회인프라가 물관리의 기능을 가져야 하므로 시민들의 환경인식과 참여는 중요하다. 따라서 본 연구에서는 시민들의 도시환경과 LID(Low Impact Development) 적용에 대한 인식을 조사 및 분석하여 LID 적용에 대한 타당성과 가능성을 분석하기 위하여 수행되었다. 시민들의 LID 인지도는 약 59%로 조사되었으나, 확대 적용에서 대해서는 46%만 동의하였다. 그러나 실제 LID 사진 및 정보를 접한 후에는 90%가 확대적용에 동의하였으며, 94%가 회색인프라와 LID 인프라를 구별할 수 있는 것으로 나타났다. 시민들은 녹지공간을 다기능의 LID 인프라 또는 그린인프라로 인지하는 경향이 있는 것으로 조사되었다. 시민들이 다기능을 가진 LID를 경관으로만 인지하는 경우 향후 LID의 확대 적용에 장애가 될 수 있기에 특화된 교육과 홍보 전략이 필요하다. LID의 확대적용을 위해서는 실질적 효과검증에 대한 결과물과 시각적 자료를 활용하는 홍보전략이 필요하다. 또한 모든 사회인프라가 시민이 살고 있는 유역에 조성되는 것을 고려할 때 향후 시민이 참여하는 거버넌스 구축을 통한 인프라의 계획 및 관리가 필요하다.
