Reproductive Company and Friedman's one-sample t-test and analysis of the effect of different dimensions on the realization of regeneretional goals in the laws and by developing the desirable criteria of legal goals based on the views of the professors and Delphi method, content validity of the later rules. The results indicate that measures taken by the redevelopment laws in the Sirus neighborhood have indirectly driven groups of residents to the outskirts of the city.
