Everyone acknowledges the fact that good management is one of the necessary and sufficient conditions for urban development programs. The theoretical pattern of urban governance that is in Endeavour to configure the best ways of urban management refers to a process that decisions and power enforcement take shape in it and is a place that the government, citizens and the private organizations interact with each other. Since the city of Tehran has different classes (affluent and poor), so it is expected that urban governance indicators be executed by the same way in the management of neighborhoods. In this respect, this paper examines the state of neighborhood management in three neighborhoods such as affluent (Velenjak), medium (Alestom), poor (Ismail Abad) neighborhoods in Tehran, to be good indicators of eight urban governance. The type of this research is descriptive- analytical and assessment and questioning tools from the group of experts. The sample size is equal to 60 questionnaires (three groups of 20 people in affluent, average and poor neighborhoods).the method of Sampling was also simple random sampling. The derived data were analyzed in SPSS software using MANOVA statistical tests, One-way ANOVA analysis within groups, post hoc LSD test and single-sample T-test. The results show that the factor of class is not affecting the good urban governance and we haven&rsquot found any significant difference among different classes of neighborhoods. The results also show that Alestom neighborhood in respect of good governance indicators is in rather medium condition, in the Velenjak neighborhood, participation, fairness and transparency indicators are low and the other indicators has been reported as moderate and, ultimately, in Ismail Abad neighborhood, all indicators except indicator of consensus (consensus) are low.

The questions of centralization and decentralization arise in every polity. The constitution or the practice or both have to settle how much of policy making is to be decided by the central government and by component bodies. By and large liberalism and decentralization tend to go together while authoritarianism tends to be associated with centralization. The constitutional model which is generally regarded as bringing about the largest amount or decentralization is federalism. This is said to sonstitute a half way house between confederacies (where component units dominate)and unitary states (where the center dominates) In its classical form at least , federalism stipulates that there have to be two independent levels of government (the centre and upper level component bodies (often named states) each of these levels has the right to decide on matters falling within its own sphere. There are difficulties in practice especially with respect to the constituent power and to the fields allocated to each level. Federalism must be based on a rigid constitution there has to be s supreme court protecting the independence of the two levels of government there has to be a second chamber defending the rights of the component bodies at the central level.yet there are variations in the extent to which the component bodies are protected and generally in the extent to which there is decentralization. On the one hand federal states are becoming more centralized on the other centralization cannot go beyond a given point without leading to gross inefficiency and perhaps to a break up of the regime as the communist experience showed. Partly for this reason there is a degree of convergence between federal and unitary states. Federalism is also associated with efforts to bring together independent states but this has occurred in a smell number of polities only. Attempts at achieving closer cooperation between states has led more commonly to confederacies, such as the Unites Nations. The European community or European :::union::: has innovated by forming a type of association labeled supranational which is intermediate between the confederal and the federal models. There is innovation in that developments take place gradually with new fields beings progressively covered new structures being set up and new member states joining. The problems of centralization and decentralization have exercised the minds of many in relation to many types of organization : both efficency and freedom appear to be at stake . federalism succeeded in a number of contexts but it is not the panacea which some suggest it is it is also so diverse that one has to refer to federalisms rather than to federalism . what is at stake is the need to find an equilibrium between the two extremes of over centralization and break up. Given the large number of situations in the contemporary world one should look for a variety of solutions and for a continuous evolution of the models which have hitherto been proposed.

Cities have been consisted of many eroded textures. The renovation designs have been provided due to many problems the residents face with. These designs are not always successful. Lack of specific pattern or enough experience regarding the intervention in the eroded textures and no suitable and enough attention to the public cooperation are some of the reasons of these designs failure. Therefore, this paper attempts to investigate the intervention in the eroded textures with an overall insight to the experiences of some countries. Paying attention to the social, cultural and economic status of the residents, providing the required infrastructures, paying attention to the ownerships, and promoting the public cooperation level are the important indices in most of the renovation designs. The purpose of the present research is to study the role of renovation and reconstruction in the world`s eroded textures descriptively. The experience of other countries have different ways of modernizing the social, economic, cultural and especially provided in partnership with samples being analyzed and then a series solution is given in the form of recommendations.
