Bylaws of Tehran detailed development plan were approved last year and its implementation has started from the beginning of the current Iranian calendar year (started March 21, 2012). It is a strategic document for urban management in Tehran and a basis for all plans in the city.

Tehran SAMA quoted Hadi Ayyazi, deputy mayor, as saying that the plan should have been implemented in 1970, but it was postponed due to problems such as high immigration to cities, high oil prices in 1972-77 and the Islamic Revolution (1979). Another plan was proposed in 1992 which was mothballed later.

He added that Tehran's comprehensive plan was formulated and notified by the government, Tehran Municipality, Tehran Islamic City Council and consultant engineers in 2008 and obliged Tehran Municipality to formulate the detailed plan whose implementation has started in the current year.

Javid, deputy mayor for town planning and architecture, said the plan uses international experiences and divides Tehran into residential, mixed, working and green areas which amount to 55 areas. Based on the plan, 39 percent of Tehran is residential, 10 percent is mixed, 28 percent is workplace and 21 percent is green spaces.

Ayyazi then added that the plan is available to citizens at www.tehran.ir which has been offered on the website to prevent possible monopoly on information related to the plan.
