1. Introduction
Urban and regional planning involves the preparation of different types of plans at multiple levels to guide development in an organized and systematic manner. Since development occurs at different spatial scales—from large regions to local neighborhoods—planning must also be structured in a hierarchical framework. This hierarchy ensures that broader development strategies at higher levels guide more detailed plans at lower levels.
The hierarchy of plans establishes a logical relationship between regional planning, sub-regional planning, city planning, sector planning, spatial planning, and detailed local planning instruments such as town planning schemes. Each level of planning provides a framework for the next level, ensuring that development decisions are consistent with broader goals and policies.
In India, planning legislation and urban development policies generally follow a hierarchical structure in which national and regional policies influence city-level and local planning initiatives.
2. Concept of Hierarchy in Planning
The hierarchy of plans refers to the arrangement of planning documents at different spatial and administrative levels, where each level provides guidance for the plans prepared at lower levels.
Higher-level plans focus on broad strategies and policies, while lower-level plans provide detailed implementation guidelines.
The hierarchy generally follows the order:
- Regional Plan
- Sub-Regional Plan
- Sector Plans / City Plans
- Spatial Plans
- Town Planning Schemes
This structure ensures coordination between various planning levels and helps maintain consistency in development policies and land-use decisions.
3. Regional Plan
A Regional Plan is the highest level of spatial planning within a specific geographical region. It provides a broad framework for the development of large areas that may include multiple cities, towns, and rural settlements.
Regional planning focuses on balanced development across the region and aims to reduce disparities between different areas.
Objectives of Regional Planning
- Balanced regional development
- Efficient use of natural resources
- Coordination between urban and rural areas
- Development of transportation and infrastructure networks
- Protection of environmentally sensitive areas
Key Components of Regional Plans
Regional plans typically include:
- Regional land-use patterns
- Major transportation corridors
- Industrial and economic development zones
- Environmental conservation areas
- Distribution of urban settlements
Regional plans often guide the development of metropolitan regions, industrial corridors, and regional infrastructure networks.
4. Sub-Regional Plan
A Sub-Regional Plan is prepared for a smaller area within the broader region defined by the regional plan. It provides more detailed planning strategies and policies that align with the objectives of the regional plan.
Sub-regional planning ensures that development strategies are tailored to the specific characteristics and needs of smaller areas within the region.
Functions of Sub-Regional Plans
- Translate regional planning policies into more specific proposals
- Address local development issues within the region
- Coordinate development among towns and rural areas
- Identify growth centers and development corridors
Sub-regional plans often focus on areas such as districts, metropolitan zones, or clusters of towns.
5. Sector Plans
A Sector Plan is a detailed planning document prepared for a specific sector or zone within a city. Cities are often divided into several sectors or planning zones to facilitate efficient management and implementation of development plans.
Sector plans translate the proposals of master plans or development plans into detailed land-use and infrastructure guidelines.
Features of Sector Plans
- Detailed land-use planning
- Infrastructure planning for roads, water supply, and utilities
- Provision of social infrastructure such as schools and parks
- Building regulations and development controls
Sector plans are commonly used in planned cities and urban development projects to ensure organized growth at the neighborhood level.
6. Spatial Plans
A Spatial Plan focuses on the spatial organization and distribution of land uses, infrastructure, and activities within a defined area. It provides a visual and physical representation of development proposals.
Spatial planning integrates land-use planning, transportation systems, environmental protection, and economic development into a coordinated framework.
Objectives of Spatial Planning
- Efficient land-use allocation
- Integration of transportation and land use
- Sustainable urban development
- Protection of natural resources
- Creation of well-organized urban environments
Spatial plans often include maps and diagrams that illustrate land-use patterns, infrastructure networks, and development zones.
7. Town Planning Schemes
A Town Planning Scheme (TPS) is a detailed local planning instrument used for the implementation of development plans. It focuses on the development or redevelopment of specific areas within a city.
Town planning schemes are particularly used for land readjustment, infrastructure provision, and orderly urban development.
Features of Town Planning Schemes
- Redistribution and reorganization of land parcels
- Provision of roads and public infrastructure
- Allocation of land for public facilities such as parks and schools
- Regularization of irregular land development
Town planning schemes help convert broad planning proposals into practical and implementable projects.
Importance of Town Planning Schemes
- Facilitate systematic urban development
- Improve infrastructure provision
- Ensure equitable distribution of land
- Support implementation of master plan proposals
These schemes are often used in developing urban areas where land needs to be reorganized for planned development.
8. Relationship Between Different Levels of Plans
The hierarchy of plans ensures that planning decisions are coordinated across different scales of development.
For example:
- Regional plans provide overall development strategies for large areas.
- Sub-regional plans translate these strategies into more specific policies for smaller areas.
- Sector plans and spatial plans provide detailed planning guidelines within cities.
- Town planning schemes implement these guidelines at the local level.
This hierarchical structure helps maintain consistency between broad planning policies and detailed development actions.
9. Importance of Hierarchical Planning
Hierarchical planning offers several advantages for urban and regional development.
1. Coordinated Development
It ensures that development decisions at local levels are consistent with regional and national goals.
2. Efficient Resource Allocation
Resources such as infrastructure investments and land development can be planned strategically across different spatial levels.
3. Improved Governance
Hierarchical planning helps coordinate the activities of multiple government agencies and planning authorities.
4. Effective Implementation
Detailed local plans and town planning schemes enable practical implementation of broader development strategies.
10. Conclusion
The hierarchy of plans is an essential framework in urban and regional planning that organizes planning activities across different spatial scales. Regional plans provide broad strategies for large areas, while sub-regional plans translate these strategies into more specific policies. Sector plans and spatial plans provide detailed planning guidelines for cities, and town planning schemes enable the practical implementation of development proposals at the local level.
This hierarchical planning system ensures coordinated and systematic development, efficient use of resources, and effective implementation of planning policies. By linking large-scale regional strategies with local development actions, the hierarchy of plans plays a crucial role in achieving balanced and sustainable urban and regional development.
