Understanding Smart Growth savings

Land use patterns affect the costs of providing public infrastructure and services such as roads, water, sewage, garbage collection, school transport and mail delivery. Various studies show that these costs tend to increase with sprawl (dispersed development outside existing urban boundaries), and can be reduced with Smart Growth (compact, planned development within existing urban boundaries).The smart growth theory criticizes the phenomenon of urban sprawl and indeed it focus on optimal utilization of infill urban land to the indiscriminate use of marginal urban areas.The methodology of this research is analytical and descriptive. THIS PAPER Summarizes estimates of Smart Growth savings. Therefore, first review the definitions of urban growth, sprawl pattern and smart growth theory will be presented and then review the specifics and their position in sustainable urban development. And finally achieve the strategies to remove the municipal casts of sprawl and Implementation Principles and strategies of smart growth theory in order to access the sustainable city.The results of this study show that cities always must provide the sustainability for ecosystem. With accession of global crisis of energy shortage, rising economic costs of households, Financial and economic crisis of governments and also a huge waste of time and energy in sprawl development, the smart growth pattern is a model that has practical answer to all these factors.
