Sustainable urban infrastructure, also called sustainable municipal infrastructure in Canada, is an infrastructure that facilitates a place or regions progress towards the goal of sustainable living. Attention is paid to technological and government policy which enables urban planning for sustainable architecture and initiatives that promote sustainable agriculture. According to the College of Engineering and Applied Science of the University of Colorado Denver, urban infrastructure refers to the engineered systems (water, energy, transport, sanitation, information) that make up a city. Challenges resulting from increasing population growth generated a need for sustainable infrastructure that is high performing, cost-effective, resource-efficient and environmentally-friendly.〔(【引用サイトリンク】url=http://www.ucdenver.edu/academics/colleges/Engineering/Programs/Civil-Engineering/DegreePrograms/SpecialtyAreas/Pages/SustainableInfrastructure.aspx )〕 ==Aspects== Roadside and urban infrastructures such as signposts, bollards and street furniture are prone to impact from vehicles and damage resulting in ever increasing costs associated with maintenance. " ''We are in the midst of global infrastructure crisis. Infrastructure worldwide is deteriorating and needs to be replaced or enhanced. Existing public funding sources are inadequate to meet the need, but the problem is more than money — What we believe is required is a broad, robust infrastructure life cycle perspective''." Deloitte Research. Closing the Infrastructure Gap. Washington, D.C., Deloitte Research. New self-healing technology protects surrounding paving and foundations from damage when items of infrastructure are impacted, reducing maintenance and improving the sustainability of urban developments. Self-healing developments result in Zero waste and Zero landfill from maintenance on items of urban infrastructure for the life of the development. According to the United States Environmental Protection Agency, the planning process of sustainable design can lead to the development of a community that is ecologically, economically, and socially sustainable.〔(【引用サイトリンク】url=http://www.epa.gov/greenkit/sustain.htm )〕 The design emphasis for a sustainable urban infrastructure is on localization and sustainable living. The aim is to reduce individual's ecological footprint according to the principles of sustainable development in areas with a high population density. The criteria for what can be included in this kind of urban environment varies from place to place, given differences in existing infrastructure and built form, climate and availability of local resources or talents. Generally speaking the following could be considered sustainable urban infrastructure: * public transport networks * Distributed generation and integrated energy demand management initiatives and programs * high efficiency buildings and other development constraints such as only permitting the construction of green buildings and sustainable habitats with energy-efficient landscaping. * connected green spaces and wildlife corridors * Low impact development practices to protect water resources. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sustainable urban infrastructure」の詳細全文を読む スポンサード リンク
