Abstract: 

A major issue in urban areas is the expansion of slums coupled with poor city planning. One of the areas encountering these challenges is Hit City, where the economy, society, services, environment, and other domains are significantly impacted. The research intends to utilize the AHP method as it serves as an excellent approach for selecting the best strategies to tackle slums. The present research used a clear and detailed method to look at several important factors, such as urban data, services and infrastructure, the economy, the environment, ownership, and how well it fits with the main plan, roads, and the costs of solutions. This helped check if the decisions were consistent and led to a final ranking of options: development, regulation, and removal. We assessed these criteria on a scale from 1 to 10, evaluating their relative comparisons and significance. The research results showed that these aspects are different from each other. The Al-Maamoura neighborhood got the highest score of 5. 92, and the chosen solution to manage it was the best one. In the Al-Farouq neighborhood, the analysis found major problems with the buildings and their design. As a result, it was proposed that all items be cleared away and individuals relocated to a different location. The study suggested 5 areas to improve, 6 areas to set rules for, and 1 area to get rid of.

1. Introduction

The issue of informal settlements and encroachments is one of the most prominent challenges facing infrastructure development projects and the provision of decent housing for every citizen [1, 2]. One of the most significant negative impacts of informal settlements is the weakness of infrastructure and the absence of proper urban planning [3, 4]. Residents of these areas suffer from a lack of access to sanitation facilities, clean water sources, electricity, poor ventilation, and other services due to the unnatural living conditions in their areas, as well as the lack of basic services [5, 6]. Consequently, these areas suffer from environmental pollution, deteriorating health conditions, and widespread social problems such as crime and unemployment [7].

Informal settlement development policies have diversified in developing countries to address the informal housing crisis. The removal-upgrading-regulation approach is one such policy [8, 9].

The Analytical Hierarchy Process (AHP) is an effective tool for multi-criteria analysis to support decision-making [10]. It provides a decision-making procedure that presents the problem through a hierarchical structure. Based on the qualitative judgment of experts and users, it relies on pairwise comparisons to prioritize alternatives and provide an overall ranking [11, 12].

2. Literature Review

Alam and Mondal [12] discuss the sanitation issue in Khulna City, which is considered the largest city in Bangladesh, with 8.14% of its total area being slums and suffering from poor sanitation facilities. Even the efforts made by the government and NGOs to improve this service do not meet the minimum requirements. This research aimed to evaluate the quality of urban sanitation services in railway slums using the Customer Satisfaction Index (CSI) to assess the gap between the reality and expectations of railway slum residents. An analytical hierarchy was used, and it was found that the satisfaction level is average. Through this methodology, the research was able to provide a clear understanding of residents' satisfaction with sanitation services, which would lead to improvements in the performance of municipalities in providing their services [13].

Dewi et al. [13], in their research, addressed the environmental and sanitation problems caused by slums. The Tangerang Municipality is planning to relocate slums in the Sisadan Riverside area and offers several alternatives to solve this problem: either relocating residents to housing in another area, maintaining their locations on the riverbank but offering alternative, simple apartments, or not relocating them and providing them with the services they need. Several criteria were established for this, including cost, technology, and acceptable environmental impact. The AHP was used to help make the best decision [14]. Figure 1 represents the research methodology.

Figure 1. Research methodology

Salari and Madrazo [14] use desk research to identify the causes and characteristics of slums, as well as the Analytical Network Process (ANP) to analyze the relationship between the SDGs and slum characteristics. A case study using the Slum Upgrading Program (SUP) utilizes cities such as Medellín, Colombia. The results of the ANP methodology demonstrate the SDGs most closely related to slum sustainability, which planners and decision-makers should consider in future planning. This is particularly true given that most cities face similar challenges, including the massive expansion of slums, a result of various factors that vary from city to city worldwide. These growing numbers of slums lead to several problems, including deteriorating air quality and poor and inadequate services. In fact, slums pose a significant obstacle to achieving the SDGs due to the lack of access to safe drinking water, inadequate sanitation, and the lack of services provided by cities. Currently, due to the large number of slum dwellers and the resulting social, economic, and environmental problems, slums remain a persistent problem worldwide [15].

Previous studies were reviewed to identify the research gap, which can be summarized as follows:

  1. Planning decision-making is crucial to managing slums and achieving sustainable cities. Making the right decision affects the success of planning policies in achieving a better quality of life for residents. Therefore, urban planners need analytical tools to help them make the most appropriate decisions for the future of cities.
  2. Most of the reviewed research was devoted to studying one of the service sectors of cities, some of which discussed the issue of sanitation, and some of which discussed the issue of drinking water. The planning decision-making regarding dealing with slums was not addressed, and this is natural, as the work of the tool differs according to the standards and alternatives that are proposed, in which the current research was able to use this tool for the purpose of making the planning decision in the most appropriate procedure related to slums in the city of Hit, and it has also not been studied previously within local studies.
  3. This research presented the appropriate solution for each informal area in the city of Hit (development, organization, or removal) and a detailed roadmap that includes the required implementation procedures based on seven criteria (urban data, services and infrastructure, economic data, environmental study, property and compatibility data, road data, and solution cost assessment).

Approximately 30% of the Hit city area consists of informal slums. These slums typically consist of dilapidated buildings, limited access to water, electricity, and sewage facilities, while facing high poverty levels, minimal incomes, and worsening ecological problems. Most previous studies have only looked at one part of slums, linking them to just one type of service, without thinking about the bigger picture of planning. Hit has not been looked at before because most research has been about bigger cities. The purpose of this article is to address a research shortfall by identifying the most effective approach to tackle this problem.

3. What is AHP

An analytical approach through this method relies on a hierarchical progression from the goal to the alternatives [16].

The analysis depends on several features, including building a hierarchical model and making comparisons between criteria and alternatives [17, 18]. Mathematical equations are also used to deduce the weights of criteria and alternatives, then reduce the ambiguity in the comparisons. After that, the process of merging quantitative and qualitative data is carried out [19, 20].

3.1 Generation of a hierarchical model

3.1.1 The proposed model - First level (Main objective)

  • Selecting the optimal alternative for treating informal settlements.

3.1.2 Second level (Criteria)

Criteria may be extracted from available data sets, combined, and grouped into main and subcategories. For example:

Urban criteria: These are derived from data such as area, age of informal settlements, urban fabric condition, accessibility, height ratio, population density, etc.

Legal and ownership criteria: These include types of tenure, encroachment type, compliance with basic design, availability of basic services, and legal framework.

Infrastructure and road criteria: These include street width, street expansion potential, parking spaces, public transportation network, sewerage coverage, water, and electricity.

Economic criteria: These include average population income, land prices, unemployment rates, and investment potential.

Social criteria: These include age structure, education levels, crime rates, and social ties.

Environmental criteria: These include pollution types, sources, impact on public health, and the presence of green spaces.

Cost and economic feasibility of solutions: These are based on the estimated cost of the solution, compensation costs, implementation timeline, and potential sources of funding.

3.1.3 Third level (Alternatives)

Alternatives can typically include:

Complete slum clearance and resettlement.

Development and improvement of slum areas (architectural and service rehabilitation).

Regulatory or legal solutions, such as legalization and modification of the basic design.

A combination of measures (such as partial development + partial resettlement).

The alternatives may vary depending on the nature of each slum area. Some areas have features that make their development more economically attractive, while others require partial or complete removal.

4. Methodology

4.1 Steps to implement AHP in Hit

4.1.1 Information from the city of Hit

Information from the city of Hit was obtained through a combination of fieldwork and select official sources. A questionnaire was given to 30 experts, including urban planners and engineers from relevant organizations, to find out which criteria are most important. The sample was conducted intentionally. The experts are special because they know a lot about the problems in the slums of Hit. Talking to local planning officials also made the information more trustworthy. The questionnaire was tested with a group of experts to make sure the questions were clear. Consistency ratios were used in comparisons with the AHP method to confirm that the results are trustworthy. Defining the goal, criteria, and alternatives.

Objective: Specified as "selecting the optimal alternative for addressing informal settlements."

Criteria: Determined as mentioned above. At this stage, it is useful to conduct a preliminary analysis of data (such as tables for urban, legal, road, service, economic, social, environmental, and cost elements) to determine the most important criteria to be included in the AHP model.

Alternatives: Determined according to potential measures for addressing informal settlements.

4.1.2 Building the hierarchical structure

A hierarchical structure is drawn starting from the top (the goal), followed by the main criteria (which may branch into sub-criteria if necessary), and ending with the last layer of alternatives.

4.1.3 Pairwise comparisons

  1. Comparisons of standards among themselves:
  • Decision makers (experts, engineers, planners, and official bodies) conduct binary comparisons between criteria: Is the urban or environmental criterion more important? Is the environmental or economic criterion more important? etc.
  • Values are usually assigned on a scale of 1 to 9 or similar, with higher numbers indicating greater importance.
  1. Comparisons of alternatives within each criterion:
  • After determining the weight of each criterion, the alternatives are evaluated according to that specific criterion. For example, under the "cost" criterion, which alternatives are less expensive? Which are more expensive?
  • The same process is repeated for the remaining criteria (social, environmental, urban, etc.).

4.1.4 Calculating relative weights

  • Based on the pairwise comparison tables, mathematical methods (such as comparison cells, taking averages of algebraic multipliers, or calculating the eigenvector) are used to derive the weight for each item.
  • The consistency ratio (CR) is checked to ensure the reasonableness of the judgments. If the CR is high (greater than 0.1), the assessments should be re-examined.

4.1.5 Prioritize and draw conclusions

  • After determining the weights for each criterion and the weights of the alternatives within each criterion, the results are combined to obtain a priority or score for each alternative.
  • The alternatives can then be ranked from most preferred to least preferred.

4.1.6 Linking to tables and detailed data

In the current case, comprehensive tables have been prepared for each informal settlement in the city of Hit. The contents of these tables can be used to assess the following criteria, for example:

  1. Urban Standards: Taken from tables (area, urban condition, rate of demolition, urban fabric, ease of communication, etc.).
  2. Legal and Ownership: Taken from tables (types of possession, type of violation, property classification, legal framework, etc.).
  3. Roads: Taken from tables (average street width, condition of entrances and exits, availability of public transportation, etc.).
  4. Services and Infrastructure: Taken from tables (sewage, water, electricity, communications, educational and health services, etc.).
  5. Economics: Taken from tables (average income, land prices, unemployment rate, job opportunities, etc.).
  6. Social: Taken from tables (age structure, education levels, crime rate, etc.).
  7. Environment: Taken from tables (type of pollution, its sources, green spaces, environmental risks, etc.).
  8. Solution costs: Taken from tables (estimated cost, implementation period, high/medium/low economic feasibility…).

Using this information, a comprehensive AHP model can be created that incorporates the criteria most influential in the decision. The more accurate and detailed the data, the more reliable the results.

5. Practical Application of the Hierarchical Analysis Methodology of Random Logic in the City of Hit

5.1 Defining the goal, criteria, and alternatives

Main objective:

Selecting the optimal alternative to address each informal area in the city of Hit, taking into account all multiple aspects (urban, services and infrastructure, economic, environmental, ownership, and compatibility with the basic design, roads, and solution costs).

5.1.1 The seven standards

  1. Urban Data
  2. Services and Infrastructure
  3. Economic Data
  4. Environmental Study
  5. Property Data and its Compatibility with the master plan
  6. Road Data
  7. Solution Cost Evaluation

The three alternatives:

development

organize

removal

5.1.2 Convert data to numerical scores (on a scale of 1 to 10)

Given the diversity of indicators (some quantitative and some qualitative), the team developed conversion rules for each indicator so that each item translates into a score from 1 to 10. Below are brief examples of the computational steps using data from each region, and we will later explain a detailed example for a specific region (for example, Al-Bakr Al-Gharbi neighborhood).

  1. Urban data - Indicators include
  • Area: Converted using the formula.

$Area\ degree =\frac{Area}{Highest\ value\ of\ area\ between\ regions} * 10$  

The largest existing area is Al Maamoura (2,086,181 m²).

For Al-Bakr Al-Gharbi neighborhood: $Area\ degree=\left(\frac{664.626}{2,086,181}\right) * 10 \approx 3.19$

Age of slums: Age score = (age of area / highest age) × 10

The highest age is 40 years (in Al-Bakr Al-Gharbi neighborhood). In Al-Bakr Al-Gharbi neighborhood: 40/40 × 10 = 10.

Urban fabric condition: To be transformed according to expert assessment; please see Table 1.

Table 1. Condition of U.F according to expert assessment

Densely Scattered with Orchard Areas

Irregular with Orchard Areas

Scattered

Gathered

= 3

= 4

= 5

= 8

In Al-Bakr Al-Gharbi neighborhood: "gathered" = 8

Ease of connectivity: All areas have a "medium" text value; we give them a score of 5.

Presence of open spaces: This is viewed from a flexibility perspective. If the answer is "yes," we give a low score (e.g., 3) because its presence alleviates the problem of overcrowding. If the answer is "no," we give a score of 8, indicating the absence of natural alternatives. In the Al-Bakr Al-Gharbi neighborhood: "no" → 8.

Presence of green areas: Same principle; all "no" are given 8.

Height rating: All areas are built on "one story"; we give them a neutral value of 5.

Condition of construction materials: “Clay and stone” = 8 (indicating low quality compared to stone only, which is given 5).

In Al-Bakr Al-Gharbi neighborhood: "Clay and stone" = 8

Population density: “High” = 8, “Medium” = 5, “Low” = 3, and “Very High” = 9.

In Al-Bakr Al-Gharbi neighborhood: “High” = 8

The simple average of all indicators within the urban dataset is then calculated; for example, for the Al-Bakr Al-Gharbi neighborhood: (3.19 + 10 + 8 + 5 + 8 + 8 + 5 + 8 + 8) / 9 ≈ 7.02.

The same conversion procedure was repeated for each area; Tables 2-8 summarizes the final results.

  1. Services and infrastructure

The authors transform indicators such as the availability of sanitation, water, electricity, communications, education, health and commercial services, waste management, infrastructure coverage, and infrastructure readiness.

Example: If it is “available,” we give it 8; “not available” = 3; “weak” = 5. In Al-Bakr Al-Gharbi neighborhood:

sewer = "no" → 3; water = "available" → 8; electricity = "available" → 8; connections = "unavailable" → 3; Educational services = "Not available" → 3; and so on. Then we calculate the average of all the indicators in this group.

For example, the average for the Al-Bakr Al-Gharbi neighborhood is ≈ 4.7.

  1. Economic data

Indicators: Land price (converted by dividing by the highest price, which is 250,000 dinars), average income (medium = 5, low = 3), unemployment rate (medium = 5, high = 3), job opportunities (weak = 3, existing = 8), and investment potential (all “limited” = 3).

For example, for Al-Bakr Al-Gharbi neighborhood:

Land price = 50 → (50/250 ×10 = 2); Average income = Medium → 5; Unemployment = Medium → 5; Job opportunities = Poor → 3; Investment = 3 ; Average = (2+5+5+3+3)/5 = 3.6.

  1. Environmental study

Indicators: Pollution type, pollution level, pollution sources, pollution impact, green spaces (if the value is numeric, we use a normalization process; for example, the highest value is 27,133, converted to 10), empty spaces (the highest value is 120,000, converted to 10), environmental risks, the presence of mitigation measures, and environmental activities.

For example, for Al-Bakr Al-Gharbi neighborhood:

Pollution type = "None" → 10; Pollution level = "None" → 10;

Pollution sources = "None" → 10; Pollution impact = "None" → 10;

Green spaces = 0; mpty spaces = 60,000(60,000/120,000 × 10 = 5); Environmental risks = "None" → 10;

Mitigation measures = "Not available" →3; Environmental activities = "Not available" → 3;

Average ≈ 6.78

  1. Property data and design compatibility

The indicators here include design compliance (compliant = 10, non-compliant = 3), availability of basic services (yes = 10, no = 3), and population (converted by dividing the value by the highest value, which is 10,000).

For example, for Al-Bakr Al-Gharbi neighborhood:

Design compliance = 10;

Availability of services = "no" → 3;

Population = 1960 → (1960/10,000 × 10 = 1.96);

Average = (10 + 3 + 1.96)/3 ≈ 4.99

  1. Road data

Indicators include: The presence of curbs (if "yes", a low score such as 3 is assigned, and if "no", a low score of 10 is assigned), the hierarchy of the street network, the average street width (e.g., "6–10" is converted to 8), the possibility of expansion (possible = 8, limited = 5), the presence of parking spaces (yes = 10, no = 3), the width of pedestrian walkways (if 0, a low score of 0), the lighting condition (clear = 8, limited = 3, non-existent = 0), the position of entrances and exits (clear = 8, unclear = 3, not available = 0), and the public transport network (available = high value, not available = 0).

For example, for the Al-Bakr Al-Gharbi neighborhood:

Presence of curbs = "yes" → 3;

Gradation = "medium" → 5;

Average width = "6–10" → 8;

Expandability = "Possible" → 8;

Parking = "No" → 3;

Pedestrian Width = 0;

Lighting Condition = "Limited" → 3;

Entrances = "Unclear" (we give it a score of 3);

Public Transport Network = "Not Available" → 0;

Total = 33, Average = 33/9 ≈ 3.67

  1. Solution cost evaluation

The evaluations here are based on qualitative cost data, where "high" is converted to 3, "medium" to 5, and "low" to 8, taking into account economic feasibility (high = 10, medium = 5, low = 3) and timescale (urgent = 10, unspecified = 5).

For example, for the Al-Bakr Al-Gharbi neighborhood (the proposed solution in the cost data is "development"):

Infrastructure improvement cost = "high" → 3;

Service cost = "medium" → 5;

Economic feasibility = "medium" → 5;

Implementation time = "unspecified" → 5;

Average = (3 + 5 + 5 + 5)/4 = 4.5

6. Calculating the Final Weight of the Alternatives for Each Area

Assuming the expert committee has decided to distribute the relative weights of the criteria as follows (total 100%):

Urban data: 15%

Services and infrastructure: 15%

Economic data: 15%

Environmental study: 10%

Property and compliance data: 20%

Road data: 10%

Solution cost assessment: 15%

The final score for each area is calculated as follows:

Total = (Score 1 × 15 + Score 2 × 15 + Score 3 × 15 + Score 4 × 10 + Score 5 × 20 + Score 6 × 10 + Score 7 × 15) / 100

For example, for the Al-Bakr Al-Gharbi neighborhood:

Urban data: 7.02

Services: 4.70

Economy: 3.60

Environment: 6.78

Property: 4.99

Roads: 3.67

Costs: 4.50

Calculation: 7.02 × 15 = 105.3

4.70 × 15 = 70.5

3.60 × 15 = 54.0

6.78 × 10 = 67.8

4.99 × 20 = 99.8

3.67 × 10 = 36.7

4.50 × 15 = 67.5

Total = 105.3 + 70.5 + 54.0 + 67.8 + 99.8 + 36.7 + 67.5 = 501.6

Final result = 501.6 / 100 = 5.02

Calculated in the same way for each region. Table 9 indicates a summary of the final results (combined scores on a scale of 10).

A development solution is recommended for: Al-Bakr Al-Gharbi, Al-Bakr Al-Sharqi, Al-Murtafa'a, Beit Rabie, and Al-Mashtal/2.

• A regulatory solution is proposed for: Al-Bakr Al-Shamali, Amina, Al-Mashtal, Ibn Sina, Al-Maamoura, and Al-Basa'ir.

• In the case of Al-Farouq, data indicates the presence of fundamental property and design violations, making the optimal solution.

Removal with resettlement according to a compensation program.

Table 10 shows the final score for each informal settlement in the city of Hit, derived from the AHP analysis, the proposed solution (development, regularization, or removal), and a detailed roadmap including the required implementation measures based on seven criteria (urban data, services and infrastructure, economic data, environmental study, property and compliance data, road data, and solution cost assessment).

Urban Factors: Conduct a thorough architectural survey to document the condition of buildings and the urban fabric and identify sectors in need of renovation. This will include updating detailed plans and redistributing plots in a cohesive manner to ensure the cohesion of the urban fabric.

Services and Infrastructure: Renew water, electricity, and sewage networks using smart monitoring and maintenance systems. Establish local service centers to provide educational, health, and commercial services at strategic points within the neighborhood.

Economic Factors: Launch support and financing programs for local investors to renovate buildings and modernize.

Commercial activities: Organize development campaigns to improve local income and stimulate small-scale economic activities.

Environmental Factors: Conduct a comprehensive environmental assessment to identify the potential for creating new green spaces and tree planting, and implement projects to establish public parks and recreational areas to enhance air quality and environmental sustainability.

Ownership: Review property records, document owners' rights, and correct any legal irregularities. Activate property dispute settlement mechanisms in cooperation with judicial authorities and raise awareness among residents.

Road Factors: Modernize the internal road network, improve lighting, and install safe pedestrian crossings. Develop the neighborhood's entrances and exits to better connect it to the main transportation network.

Solution costs: Prepare a detailed feasibility study to estimate the total development cost and identify funding sources (bank loans, government support, private partnerships).

7. Discussion

According to Alam and Mondal [12], the researchers explored the less affluent sectors of Khulna City and gathered residents' opinions on the effectiveness of the sanitation services available to them. Dewi et al. [13] explored several methods for transporting individuals within a town in Indonesia, concentrating on the associated costs and environmental effects. Salari and Madrazo [14] explored the relationship between the ANP and the SDGs in the context of slums, emphasizing a worldwide approach instead of a localized view.

While these studies hold significance, they concentrated primarily on a limited number of topics such as services, environmental concerns, or social issues. A majority of earlier studies have concentrated on major cities in Asia and Latin America, neglecting the unique characteristics of medium-sized cities such as Hit that face different social challenges and economic realities. This research is special because it uses the Analytical Hierarchy Method (AHP) in a combined way based on seven important factors: urban, service, economic, environmental, ownership and plan fit, roads, and solution cost. To facilitate an exact evaluation of distinct choices in an area that earlier studies have not examined.

8. Conclusions

Based on data analysis and application of the Analytical Hierarchy Method (AHP) on the seven criteria (urban data, services and infrastructure, economic data, environmental study, property data and compatibility with the basic design, road data, and solution cost assessment), the following is evident:

  1. Variation in indicators between Neighborhoods: The results reveal clear differences in indicators between informal settlements. Some areas, such as Al-Bakr Al-Gharbi and Al-Murtafa'a, score higher in urban and economic data, indicating development potential to modernize infrastructure and stimulate economic activity. In contrast, areas such as Al-Bakr Al-Shamali and Ibn Sina score lower, reflecting the need for careful regulatory intervention to control the urban fabric and resolve property issues.
  2. Variation in environmental aspects: Environmental performance varies significantly. Some areas (such as Beit Rabie) scored high in the environmental study, while others (such as Al-Mashtal and Al-Mashtal/2) scored low. This calls for specialized environmental interventions to enhance green spaces and reduce environmental risks.
  3. Importance of property data and compatibility with design: The results of the property data assessment show significant variation. Some areas, such as Al-Maamoura, achieve high compatibility with the urban plan, while others suffer from low compatibility scores, highlighting the importance of implementing effective property dispute resolution mechanisms and correcting land registry data. 4. Impact of Solution Costs: The costs of specific solutions were evaluated based on precise criteria (such as the cost of infrastructure improvement, economic feasibility, and implementation timeframe). It is noted that solution costs vary across regions, which influences the selection of the optimal solution. Some regions require low-cost regulatory intervention, while others require comprehensive development investments.
  4. Identifying the optimal alternatives: Through a final aggregation process using the relative weights assigned to each criterion, the following solutions were recommended:

o Development Solutions: In areas with good urban and economic potential, such as Al-Bakr Al-Gharbi, Al-Bakr Al-Sharqi, Al-Murtafa'a, Beit Rabie, and Al-Mashtal/2, where infrastructure can be improved and urban plans modernized while stimulating investment.

o Regulatory Solutions: Recommended in areas with urban fabric disturbances and property issues, such as Al-Bakr Al-Shamali, Amina, Ibn Sina, Al-Maamoura, and Al-Basaer, with a focus on reorganizing uses and implementing dispute resolution mechanisms.

o Procedural Solution – Demolition with Resettlement: This is the optimal option in the case of Al-Farouq neighborhood, where data shows significant property and design violations that require the removal of violating buildings and the implementation of a comprehensive compensation and resettlement program.

9. Recommendations

Based on the analysis results, the article recommends a detailed implementation roadmap that takes into account all seven criteria, as follows:

  1. Forming a specialized supervisory committee:

o Establishing a committee comprising urban planning experts, representatives from government agencies, the private sector, and representatives from the local community.

o Using geographic information systems (GIS) to update and monitor field data periodically.

  1. Implementing development solutions in appropriate areas (such as Al-Bakr Al-Gharbi, Al-Bakr Al-Sharqi, Al-Murtafa'a, Beit Rabie, and Al-Mashtal/2):

o Urban Structure: Conducting accurate architectural surveys to redraft detailed plans and distribute plots in a cohesive manner.

o Services and Infrastructure: Renovating water, electricity, and sewage networks using smart technologies, and establishing local service centers to provide educational, health, and commercial services.

o Economic Support: Stimulating local investment through financial support programs and investment incentives, and implementing development campaigns to enhance economic activity.

o Environmental Aspect: Implementing projects to create public parks and plant trees, while improving waste management to reduce pollution.

o Property Data: Reviewing property records and settling legal disputes through transparent mechanisms.

o Road Network: Upgrading the internal road network, improving pedestrian paths, and installing Modern lighting systems.

o Cost and Financing: Preparing a detailed feasibility study to estimate costs and identify various financing sources (such as bank loans, government support, and private partnerships.

  1. Implementing regulatory solutions in areas that require urban fabric control (such as Al-Bakr Al-Shamali, Amina, Ibn Sina, Al-Maamoura, and Al-Basaer):

o Regulating uses: Redistributing buildings and dividing areas into small administrative units to improve oversight and regulate uses in accordance with the official plan.

o Settling property: Implementing expedited regulatory procedures to resolve real estate disputes and update legal ownership data.

o Developing infrastructure: Improving vital facilities on a limited scale while updating the road network and traffic signals, without the need for comprehensive interventions that may require significant investments.

o Community engagement: Holding periodic workshops and meetings with residents to raise awareness and coordinate efforts among various entities.

  1. Implementing building demolition and resettlement procedures in critical cases (such as Al-Farouq neighborhood):

o Gradual Demolition: Preparing a detailed report to identify and classify urban violations, then implementing the gradual demolition of the violating buildings in coordination with judicial authorities.

o Resettlement Program: Developing a comprehensive program that includes appropriate financial and housing compensation for affected residents, in addition to re-planning the area after demolition in accordance with the city's master plan.

o Legal Follow-up: Providing legal and administrative support to ensure the rights of all parties and strictly enforcing regulatory procedures.

  1. Performance monitoring and evaluation:

o Adopting a periodic evaluation system to measure the impact of implemented solutions on improving urban, economic, and environmental indicators.

o Updating data and using modern analytical techniques to ensure continuous improvement and modifying implementation plans as needed.

In short, this detailed roadmap enables decision-makers to formulate a comprehensive implementation program that responds to the needs of each informal settlement in the city of Hit, ensuring sustainable and equitable urban development while taking into account environmental, economic, social, and legal aspects.
