The structural point of view which dominated decision makers and decision designers in urban management has been causing a lot of problems. Different cities got closer to the rivers and even a part of the stream have buried in the culverts in cities such as Tehran to maximize the use of the land on the riverbank and the bed. Ideas about the natural elements in the cities have been changed over the time. The emerging of concepts such as green infrastructure and low-impact development rise to the daylighting projects. Daylighting process reagents project that all or a part of the stream, creek or drainage system excavate from underground and open to fresh air and then take steps such as remediation, rehabilitation and restoration can be done for it. The delighted stream can raise property values and investment opportunities, creating public open spaces and reduce maintains costs for buried channels. Dominated structural considering for flood control cause problems for Tehran’s streams and rivers, such as diverting to rigid channel and narrowing channel, over polluting by wastewater entrance, burying beneath covered channel and culverts, concerted bed, diverting from the main direction, etc. Rehabilitating and restoring Tehran’s streams and rivers can reduce problems caused by flood and improve environmental quality too. Based on this regard, there is no legal gap and will not have the financial burden of the municipality in the long-term period so it seems daylighting streams in Tehran can be done as soon as possible.
