Propose a Model of Urban Landscape Management Deal with City Vandals : A Case Study of 20 th District of Tehran

Vandalism is one of the hidden results of the rise of modernism that appearance of this phenomenon can be seen in city centers, schools, sports club, etc. in abundance. And today in urban communities is considered as a serious problem that compromises safety and security of urban communities. Destruction of the urban landscapes by the vandals and loss of interests of citizens in the case of the city face that creates confusion and chaos of urban landscape is not a new problem. And at least in the last three decades considered by the social activist groups and NGOs, environmental scientists, artists, city managers and ordinary people directly and indirectly. It exists convergence and consensus on the desirability of merging the face of the city and reducing urban landscape and urban landscapes as part of a person's identity and is known aspect of human existence. The purpose of this article is providing a model of urban landscape management in dealing with urban vandal from the perspective of residents and administrators. Using existing literature, beginning some management indicators to assess the effects of mining and based on required data were collected through questionnaires from district 20 in Tehran. Study, methods that fits the type of data model is used SWOT and statistical methods to analyze data without parameters. The results show that the effects of vandalism in the considered area were been and can be customized according to the features and functionality and urban potential in this area and by applying strategic planning, according to the aforementioned factors and in the shadow of integrated management sustainable development in order to reduce the effects of destruction in this region. It also seems to be the best kind of theory about urban management in the region, a new theory or system. And in 20 District management model in order to deal with urban vandalism attention to the planners and policy makers in different dimensions is considered. As well as monitoring and planning should be limited to the initial phase and policies But also in the design, implementation and maintenance of urban spaces, urban furniture, etc. should also be considered And in this respect also must be careful.


Introduction
All societies with different extents in some way involved with aspects of urban vandalism and negative consequences of this damage.Daily life of every citizen in dealing with behavioral manifestations associated vandalistic behaviors.The existence of such a threat to public property in the city, in some form for many citizens is sensible.Guards beings for places such as subways or warnings and signs in public places in order to avoid polluting the environment or to inform the graffiti etc. suggests that these areas coveted by the vandals and their damaging behaviors.All of these behaviors damaging to the institutions of this property and places, that they are responsible for the preparation and maintenance, financial losses and reproduction costs of repair, replacement and cleaning is involved.Including corporate institutions that have entrusted this responsibility at the macro level are municipalities and the organization, acting on behalf of Vandalistic damage and repair costs considerably.In fact, a large part of the increased budget that can be spent on development, construction and beautification of the city, always vandalistic measures to eliminate the offset is assigned.However, the costs that have been created generally compensate by the taxes that will be collected from people.In fact, the people indirectly bear the costs of repair and replacement of public facilities.Confusion face of the city and appearing more chaos in the urban order and reduction of the security feeling of the citizens in the wake of a turbulent life in urban space are another dimension of objectivity adverse effects vandalistic measures in urban areas.An example of a survey report states that the destruction of public property in Tehran Costs incurred in 1594 destroyed the public telephone system in 1388, 63.45 billion Rials.According to an official at the telecommunications company on the basis of studies conducted approximately 30% of the public telephones in the country imposes losses amounting to billions Rials in government spending.He added that every month approximately 8800 damages and 800 cases of theft in connection with public telephones are recorded.(E-books citizenship customs, 2009, p9) To understand the causes of these behaviors can be partially to prevent or control of it.These behaviors may be influenced by another parallel social problem is the feeling of oppression and injustice that sense of deprivation is linked to the problem.That sense of economic deprivation, social and services.Perhaps this dissatisfaction with municipal service delivery with the destruction of public property by citizens as a protest or express their anger with each other.(Mohseni Tabrizi, 1374. 19) 20 th District (Rey) is the southernmost urban area in the municipality of Tehran.Due to some factors, such as damaging and abandoned buildings inside the city, narrow streets, Being abandoned of more buildings, long-term buildings damage and ... this area is today one of the most important centers of the incidence of vandalism.That every year causes a lot of damages, including the destruction of public property, destruction of urban furniture, destruction of school property, historic buildings and ... that has hidden and known results and impacts across the 20 th District.According to the above explanation this study attempts to determine the different types of economic deprivation, social exclusion and also how much the denial of civil service tends to affect vandalism.

Theoretical Foundations
Increasing urbanization and urban spaces because of their inherent variability that is associated with, leads to the spread of social harms.Something that has been experienced in many countries.Problems and damage caused by urbanization in the developing countries of much higher dimension and the thriving cities of these countries the problem is more severe.(Ghaqeleh, Kalhor, 1389, 15) On the other hand machine civilization that followed today by development of industrial cities densely populated neighborhoods, lifestyle changes, weakening social cohesion, failures and hidden psychological complexes and suppressed desires and failed aspirations and exacerbate feelings of helplessness, frustration,, disability and abuse is brought, has other consequences.And the growing rebellion of people, especially the younger generation against repressive social realities and external forces.In cities due to population density, moral density, different cultures, values diversity, competition, individualism and collective morale and cohesion to overcome the mechanical and organic solidarity, separation, alienation, diversion and isolation of the individual from society and societal norms manifesting anomic conditions over the rural areas is evident.The existence of informal settlements in the towns borders, dark streets and under bridges, streets and squares geometric shapes, ways unauthorized access to highways, tall buildings and high density too, are abandoned half-built buildings and dilapidated, uncontrolled urban development, including the causes of crime today.(Abdullah Puri, 1390, 5) At the societal level in the form of mass opposition protests and riots occur and such behavior when they became the characters, creates vandalism and related human damages.Vandalism is one of the hidden results of the rise of modernism that appearance of this phenomenon can be seen in city centers, schools, sports club, etc. in abundance.And today in urban communities is considered as a serious problem that compromises safety and security of urban communities.Flacks (Flacks, 7, 1971) Depending on the application and purpose of the classification of different types Vandalistic behavior can be based on location (city, village, forest, etc.), scope (cultural, political, ...) combined agents (individual or collective), motivated action (entertainment, protest, approved the acquisition in the group) and other aspects divided.Criminological research into vandalism has found that it serves many purposes for those who engage in it and stems from a variety of motives.Sociologist Stanley Cohen describes six different types of vandalism: 1. Acquisitive vandalism (looting and petty theft).
2. Tactical vandalism (to advance some end other than acquiring money or property -such as breaking a window to be arrested and get a bed for the night in a police cell).
3. Ideological vandalism (carried out to further an explicit ideological cause or deliver a message).
6. Malicious vandalism (damage caused by a violent outpouring of diffuse frustration and rage that often occurs in public settings).
From a social perspective vandalism could be classified in five groups: avarice, tactical, avenger, recreation and hostility.
Destruction of the urban landscapes by the vandals and loss of interests of citizens in the case of the city face that creates confusion and chaos of urban landscape is not a new problem.And at least in the last three decades considered by the social activist groups and NGOs, environmental scientists, artists, city managers and ordinary people directly and indirectly.It exists convergence and consensus on the desirability of merging the face of the city and reducing urban landscape and urban landscapes as part of a person's identity and is known aspect of human existence.According to Prushansky part of the personality of every human being makes his individual identity is the place where he identifies with it and identify the others.In fact, the quality of the physical environment on the quality of work life and social and mental health has a direct effect.
It is suggested that for each of the role-related identities of an individual, there are physical dimensions and characteristics that help to define and are subsumed by that identity.In addition, there is a general place-identity for each individual which reflects his or her unique socialization in the physical world.Review of different doctrines and theories about the environment and landscape shows urban landscape is two-dimensional that its main dimension is human and personal and social behavior in the environment.On this basis we can say environmental and urban space management regardless of behavioral indexes is impossible.Also review of books and comments of masters of urban design and architecture like Lynch, Rappaport and Aplyard and criteria lay down by Ian Bentley and his colleagues can be used as criteria and indexes in order to verify the local identity and sense of belonging of citizens to the places and spaces where considered Criteria such as mean, diversity, richness, personalization capabilities (Sense of belonging) covering a wide range of human relationship with the made environment and according to these criteria are effective in reducing vandals behavior and vandalism.(Municipal monthly magazine, 1383, 11) Paintings exhibited in galleries, ancient furniture and antiques in museums, monuments and religious sites, Statues installed in squares and public places houses, haunted, parks and public gardens, passages lights, seats for buses and subways, library books, public telephones, urban furniture , spaces and public facilities and bombings aimed at the destruction of public property, destruction of natural persons and legal facilities, destruction of school property, demolition of traffic signs and traffic signs and dozens of other topic of destruction are issues that the damage or failure of them was caused by vandalism and are destroyed.In the meantime, studies and experiences of experts, reflects the importance of the issue of vandalism in various aspects of Iranian society (Mohseni Tabrizi, 1374., 19) Mr. MostafaPour (Director of Studies and Planning Social Affairs and Cultural Center in Tehran) in the first special session entitled "Vandalism in Tehran," said in the last 20 years, maintenance costs of Tehran are 5 trillion Tomans, But now half the cost of Tehran Municipality are maintenance costs that half of this amount will be spent on repairing vandalism damages.However, despite the provision and codification of façade criteria and preparation of design studies and urban landscape of roads and urban spaces in Iranian cities in recent decades, so far indexes and measures of social psychology and human characteristics and behavior of beneficiaries are not emphasized so much in the urban landscape and has been hidden from the eyes of planners and urban designers.
In the study of urban landscape design too much emphasis on framework -functional goals and lack of attention to the mental, emotional, cultural and behavior needs of citizens been evident, so that due to the lack of attention to place identities and citizens' fixation, vandal active presence in urban spaces, abnormal social behavior and destruction of urban landscape has been increasing....Over the years and recent decades Tehran has had staggering growth and the bulk of the immigrants of the country have accumulated in this city.Urban population concentration has led to accumulation and concentration of urban problems.Tehran 20th District is located in the southern part of the metropolitan area, and because some features have been one of the main centers for immigrants that today have the high population density.Today this area is one of the most important centers of the incidence of vandalism.That every year causes a lot of damages, including the destruction of public property, destruction of urban furniture, destruction of school property, historic buildings and ... that has hidden and known results and impacts across the.For an instance it affected on the quality of urban life in the 20 th District.And an increase in aggression and violence in cities not only in effective in low working efficiency and general use the studied area, even affect in the increasing of fear feeling and unrest and abnormalities.In this area there are the same and indigenous social structure, the structure of the old worn, population density and moral density, some different cultures, deviation and separation from society that different economic classes are located.Due to the different characteristics of social and economic in region of "Shahr -e-Ray" and existence of new and old natural -historical spaces and views in this region and also seeing the effects of vandalism in the face and body of roads and buildings, this area can be a good case study for study and research on urban management, urban landscape against the vandals, so that we can extend these studies to other parts of Tehran.This study tries to answer these questions by conducting a systematic review and precise and finally propose a model of efficient management of the urban landscape.

Research Method
This research in terms of target is an applied research group, the methodology based on the explanation -survey and includes a two-stage survey to examine and describe the documents and analysis.
In the first stage with the help of library studies and documents, the theoretical framework and the hypotheses have been prepared and in order to assess (accept or reject) the hypothesis with the help of survey and analytical methods of determination (experimental) they are tested.Explanatory method refers to methods and studies seeking to find cause and effect relationships between different variables.In the relational hypothesis the independent variable (x) is usually one of the causes of the characteristics of the dependent variable (y).In this study, data collection is done using field methods, library, questionnaires and interviews with people and related officials.For this purpose, direct referring to statistical and using the information of cities, comprehensive information for the study was provided and then completed through questionnaires, interviews and field studies mentioned.According to the purpose of the study in case of urban management model against city vandals, 20 th District in Tehran, statistical society includes citizens, vandals and managers.Since the statistical society in this study, is 20 th District in Tehran urban residents, managers (16-24 years) are as the studied population.For urban residents (16-24 years) using the Cochran formula was conducted to determine the sample size.Therefore the numbers of citizens in the 20 th District, 382 civilians have been obtained.Because the number of vandal was not identified in the studied area, adjustment formula was used to determine the sample size.As a result, 322 people were identified as resident sample size.For city managers, due to the limited number of them, used the method of referendum.In this study, to analyze the data, SPSS software and statistical methods including correlation test, Chi-square and SWOT analysis model are used.

The Studied Area
Tehran 20 th District is limited from north to Azadegan Highway and 16 th District, from west to BeheshtZahra (the main cemetery of Tehran) and 19 th District, from east to DolatAbad St, Bibi Shahrbanu Mt, and TaghiAbad road and 15 th District, from south to south villages and territory of "Shahr-e-Rey".This area is located about 1,050 meters above sea level, and passes it Darabad, Darband, Tochal and Sorkhehesar rivers.Based on the new division of Tehran Municipality, Tehran Metropolis is divided into 374 neighborhoods.Meanwile 20 th District, has 21 neighborhoods.This area encompasses ancient city of Rey that the origin of one of the earliest origins of civilization in Iran near Cheshmeh-Ali's resignation.20 th District (Rey) is the most southern urban area of Tehran Municipality.The criterion action surface of Municipality is 2264 hectares.Rey weather is mild and dry.Within 20 th District up to 2394.3 hectares, a wide range of territory (over 25%) is residential zone.Although most residential applications located in residential zone but, in the mixed zone, the activities of the conservation and only residential are deployed.The vastitude of residential use in the region is 622 hectares which a large part of it (along with the road network and services) is located in a residential zone The average household size of mentioned district is equal to 3.3 people in the same year and the ratio of 14-year old population to the total population is equal to 2.35 percent.The sex ratio (number of males to females) in the region is equal to 1.03 that this figure is lower than the sex ratio of the city (1.04)About 58.7 percent of the population in this region are married that is more than the average of the city (57.2).In this region dependency rate (the ratio of employed people to the total population) is equivalent to 3.26 persons and it's more than the 2.96 dependency rate in the city.Illiteracy rate in the region is 9.6 percent more than the rate of illiteracy in the city (6 percent).During the ten-year period from 1375 to 1385, about 9.6 percent of residents have entered the neighborhood.The unemployment rate in the region (8.3%) and higher than the city (7.5 percent) The percentage of the active population in the region is about 83.3% less than the percentage of active population (about 41.5 percent).7-fold classification of spatial organization and typology of functional structure in 20 th District has been proposed.It should be noted that the boundaries of these lines matches with regional and national documents identified areas detailed plan.The above-mentioned categories are as follows: 1. the old buildings 2.construction industry 3.historic -religious buildings4.greenspace 5.Passages 6.agricultural structure 7.residential buildings According to the Supreme Council for Planning Architecture a surface equivalent to 98 hectares of old buildings (third kind) three conditions are throughout 20 th District that need urgent and immediate intervention.On the other hand, based on studies other problematic and old constructions in addition to 98 hectares in this area are as follows: 1.Old and organic buildings in the area around the shrine of Hazrat AbdulAzim (AS) in the space of 144 hectares that some parts of it have been identified in the map of Supreme Council for Planning and Architecture.
2. Old, problematic, residential and manufactory buildings is located near the historical and valuable area in Cheshmeh Ali and Tuqrul Tower in the space of 91 hectares that this area has also part of the old buildings that have been identified in the map of Supreme Council 3. Old and problematic construction (workshop and industrial) in the northwest and the Javanmard Ghasab Alley in 231 hectares area.The map of Supreme Council only small parts of Javanmard Ghasab Alley has been identified.However, in the industrial area at the north of this region due to the lack of residential areas, it does not exist any aging buildings in the map of Supreme Council.While the industrial area to in north of this region is one of the very old buildings and structures within the area is abandoned, Moreover, it has much potential to develop the area south of Tehran.Among the main characteristics of these constructions in the urban vandalism can be contributed to the following items: 1-Monuments destroyed and abandoned inside the region.
2-Narrow streets, more abandoned buildings, long-term damage of buildings to the facial tissue.Industrial and workshop in texture with an area of 489 hectares Rey range is included.
Industrial and manufactory buildings in Shahr-e-Rey is an area about 489 hectares.This area is in the north and DolatAbad District and West Shahid Rajai Blvd and parts of the neighborhood Alaeen on the highway Tehran -Varamin.Concentration of industrial activities, car repair, etc. in the area of the salient features of the studied area.In the historical -religious region existence of Abdul-Azim shrine (AS) as well as monuments such as Tugrul Tower, Cheshme-Ali and the tomb of Ibn Babawayh has Outstanding Tourism Property.According to this historical -tourism of this region with an area of over 230 hectares is spread around historical monuments.Green spaces with a total area of 250 hectares mainly in the northwest and northeast parts of their range.Existence of sports and recreational spaces in regional parks has increased the boom and population of these spaces.Now one of the issues that can affect an increased incidence of vandalism in these spaces can be mentioned the following: 1-Lack of proper lighting at night 2-Creating a cozy and quiet corners in the parks The passages in this report are first-degree commercial and arterial streets.This range is in the centrality of Shahr-e-Rey Sq and streets and Fedayeen Islam St, Zakariya Razi St and also encompasses Ibn Babawayh.In fact, this range is also the communication route between the city's historic cores.Existence of commercial spaces, pedestrian presence in these spaces during the day and lack of social supervision at night due to the closure of shops is characteristic of this region.Mainly agricultural land in 20 th District and the neighborhood of Estakhr and Nafarabad are located in the southern area.There are barren lands and abandoned at the edge of the area that is considered as a property.About 1,000 hectares from construction dedicated to residential construction.The construction boom in the region and increasing building density in recent years has added to the population of the region.According to the detailed plan there are sufficient per capita services at a local level that is one of the strengths of the residential construction.
The important point in relation to this building in the neighborhood with green spaces and industrial area that due to inadequate public supervision for the construction of residential buildings, as well as vandalism and destruction oriented perspective is influenced.According to the researches and, as the map shows the number 4, the most vandalism occurs in the residential constructions, outdoors and industrial constructions.Acquisitive vandalism usually occurs in the industrial constructions.According to the conclusion of researcher and experts' view, The reason for this is unrelated to the lack of social control spaces, especially at night, and the lack of a sense of belonging from tradesmen and employees in this area to their business environment.Also in residential construction and green spaces, play vandalism has a high percentage.At first glance, this phenomenon can be regarded to the presence of young people in these areas and the need for recreational and energizing activities.Because this opportunity based on sports and recreational capita in the area is low and especially in the old construction and the lack of perspective in these areas per capita can be seen in vandalism and appearance of per capita deficit can be seen in these regions from vandalism view.In the following showed dominant vandalism map in each of the seven areas of Space Agency.As it is obvious on the map, ideological vandalism, play vandalism and acquisitive vandalism are the highest density and the percentage of replicates in Rey.As shown in Figure 3 play and ideological vandalism have high percentage of building in 20 th District.In fact, the main problem in residential and history -tourism buildings and green spaces of in vandalism view is play or ideological vandalism and sometimes acquisitive vandalism.The map indicates that as much as we move from the residential area to the industrial area, in fact we move from vandalism diversity and the birth of vandalism view toward avarice and vindictive vandalism and the statistics this type of urban vandalism increases.Following the distribution map of vandalism seen in 20 th District are presented.In this map, based on the vandalism number of each quintuplet groups (acquisitive, play, ideological, vindictive and tactical vandalism) cases have been recorded and is formulated in the form on below map.As is clear in Figure 4 vandalism statistics in the residential buildings and green space area is higher than in other spaces.Also, the minimum vandalism statistics is owned agricultural land and its surrounding area.It can be attributed to a lack of grounds for acts of vandalism, because of lack of urban walls and the lack of urban furniture in this area not provided enough time to vandalistic acts.According to maps of the spatial structure as well as the dominant type of vandalism in each of the areas and buildings identified in 20th District The results can be derived from these maps are analyzed and presented in the following field observations.Monitoring of community and a sense of belonging in the environment has a direct correlation with the incidence of vandalism.Depending on the prevalent type of vandalism in the industrial area that is vandalism of avarice, compared to common recreation vandalism in the old and residential construction, it can be concluded that if the sense of belonging to the building and also social control over urban spaces increase, will influence to vandalistic actions and leads them from vandalism avarice to ideological and recreation vandalism.The level of social control in urban areas directly linked to decreasing the amount of vandalism.According to the rate of vandalism in the historicaltourism and residential area than vandalism rates in industrial areas it can be stated if the level of social control in urban areas increased, the rate of vandalistic actions may decrease There is a reverse relationship between the quality of construction and the repetition of vandalistic acts.In other words, as the quality of urban spaces better and aesthetically is more desirable, vandalistic acts will be seen less.By comparing the abandoned spaces inside the old buildings and new residential areas in the studied area, it can be concluded spaces that had the lowest level of quality of have had a greater number of vandalistic acts.As well as the spaces with appropriate urban furniture and higher quality had less vandalism With regard to the comparison of residential areas with each other it seems that there is indirect proportion between economic level of resident families and the price of land against urban vandalism.In fact, with increasing economic status of urban households, there are fewer vandalistic actions in the area of household's residence Indirect ratio between the quality of the buildings built and urban vandalism in urban area are in the 20 th District.In fact, in the old empty buildings, there are abandoned spaces and dilapidated buildings.These spaces and buildings are suitable place for vandalistic acts such as graffiti, fires, collecting garbage and....While in these regions, areas that are more appropriate in natural status, there is less vandalistic acts.

The Results and Consequences
In order to present the pattern of the city view against vandalism: case study: 20 th District of Tehran Studying the 4 factors (SWOT) in reducing problems and improving the situation is necessary.After studying the 20 th District of Tehran and getting people`s ideas, the following has been made.According to the questionnaires these solutions are presented: first the inner and outer items have been studied through SWOT and then people`s opinion are presented.Via people`s ideas and city management these findings are shown on social financial cultural and management point of view.These are as shown beneath according to the reduction of vandals: Based on this analysis, can be proposed a the following as the most important challenges of urban management in "20 th District of Tehran" in dealing with different aspects of urban vandalism: • Failure of crisis management

•
The presence of disabled and weak people in urban spaces According to the proposals in the field of urban management in different dimensions and using SWOT analysis is tried to provide priority and optimized strategies in different dimensions.For this purpose, using SWOT analysis on different aspects of the strategy is provided.It should be noted in order to provide optimal strategy In addition to considering the views of the people and officials SWOT table parameters in each dimension is concerned.In order to prioritize strategies and to obtain optimal strategies in each dimension of the design and planning action is strategic evaluation using Qspm techniques.In this method, Internal and external environment of studied area in each of the social, economic, framework and management aspects, is examined.As a result of the 4 strategies presented in the SWOT matrix (offensive, defensive, compliance and contingency Strategy) strategic priority will be identified in any dimension.
In this part internal and external factors which is obtained from the social dimension is evaluated in table .....The economic dimensions of the internal and external factors that are obtained from the evaluation are shown in Table 7.According to the study's results ,they're familiar with comments of Ian Bentley and his colleagues, Jane Jacobs, Huber, fairness -Control Fisher and Baron, Janleng, David Chapman and anomie theory of family.In general, urban management should be coupled with proper planning and proper management in order to develop the area and to reduce vandalism.The sustainability of development in the region leads to the balance of the city in all aspects of economic, social and cultural fields.Therefore due to the facilities, capabilities, urban potential in this area and by applying strategic planning based on these factors and in the shadow of integrated management, achieve sustainable development in order to reduce the effects of destruction in the region.It also seems to be the best kind of theory about urban management in the region, is modern theory or a systematic theory.Reports and studies about vandalism often have proposed solutions based on their findings to intervene in the matter that can be mentioned strategies in them, generally categorized in four areas Also, in the most sources, been emphasized to the two important steps: strengthen knowledge and specialization in face to the issue.

Strategies to Reduce the Effects of Vandalism
The first step: Strengthening vandalism knowledge is known as a small crime which can be a background to bigger crimes and from this point of view, dealing with is a significant need for the development of society and neglecting it will leave irreparable effects.A serious obstacle for the deal with this phenomenon, weak statistics and researches in this field.Plan to reduce vandalism we need to know the criteria such as size, intensity, amplitude, frequency and diversity of sabotage.And that destruction has taken place in what areas (health, leisure, environment, services, education, sports, etc.)One of the few comprehensive studies in this area was Mr. Mohseni (1374) in the metropolitan area of Tehran that was done by the municipality and the Institute for Social Studies and Research of Tehran University.Other research is limited, inconsiderable and periodic.In short, the phenomenon is not known; deal with it would be meaningless.Reduce the problem of vandalism in case of complete identification needs the firm determination of authorities and macro decision-makers of community and activity and appropriate intervention of cultural, technological, educational, educative and welfare functions.Given the priority strategies identified and presented on various aspects as well as chi-square test variables, we can be proposed a management model in "20 th District" in order to deal with urban vandalism.In this model attention to designing and policy in various aspects is considered.Also monitoring and planning should not be limited to the initial phase and policies but should be considered in the design, implementation and maintenance of urban spaces, urban furniture, etc. and in this respect also to be noted.On this basis, and considering the explanations of urban management requirements mentioned in the theoretical foundations.Range of measures in urban management in the issue of vandalism in this study, divided into three-level structure.
Before execution: Including policy and planning Execution: Including locating and installing street furniture and other design elements environment Maintenance: the preservation and restoration of urban furniture, urban spaces and removal design defects and failure.The strategies presented in social, economic, framework and management classified in three steps.

Figure 1 .
Figure 1.Location of 20th District in TehranIn 1390, the population of 20 th District based on stats of the Statistical Center of Iran was the equivalent of 340,861 people.The average household size of mentioned district is equal to 3.3 people in the same year and the ratio of 14-year old population to the total population is equal to 2.35 percent.The sex ratio (number of males to females) in the region is equal to 1.03 that this figure is lower than the sex ratio of the city (1.04)About 58.7 percent of the population in this region are married that is more than the average of the city (57.2).In this region dependency rate (the ratio of employed people to the total population) is equivalent to 3.26 persons and it's more than the 2.96 dependency rate in the city.Illiteracy rate in the region is 9.6 percent more than the rate of illiteracy in the city (6 percent).During the ten-year period from 1375 to 1385, about 9.6 percent of residents have entered the neighborhood.The unemployment rate in the region (8.3%) and higher than the city (7.5 percent) The percentage of the active population in the region is about 83.3% less than the percentage of active population (about 41.5 percent).7-fold classification of spatial organization and typology of functional structure in 20 th District has been proposed.It should be noted that the boundaries of these lines matches with regional and national documents identified areas detailed plan.The above-mentioned categories are as follows: 1. the old buildings 2.construction industry 3.historic -religious buildings4.greenspace 5.Passages 6.agricultural structure 7.residential buildings
