Development of urban market spatial for highest and best use of land productivity and sustainability

No less than 40% of around 70 traditional retail markets in Surabaya are located in the downtown area where the economic value of the location is high, but not being optimally utilized. Sustainable planning can be achieved if the area is not only able to stand and grow by itself but also contributes to the economic growth of the region and the surrounding trade.
