Planning Framework: Urbanisation, Charters, the Constitution, Programmes and the Hierarchy of Plans
2. International charters and mandates for planning
These instruments are not Indian law. They supply the vocabulary and the targets that national policy and plans borrow, so for each one know the year, the place and the single idea it carries.
| Instrument | Year, place | Core idea | Use in planning |
|---|---|---|---|
| Athens Charter (CIAM) | 1933; a congress held aboard a ship from Marseille to Athens; published by Le Corbusier in 1943 | The functional city: dwelling, work, recreation and circulation as four functions kept apart by zoning | Source of strict single-use zoning in master plans |
| Charter of Machu Picchu | 1977, Peru | Critique of Athens: rigid separation of functions ignores people, culture and context; asks for integrated, flexible planning | Supports mixed use, community and cultural identity |
| Habitat I | 1976, Vancouver | First UN Conference on Human Settlements; led to a UN human-settlements body, now UN-Habitat, in Nairobi | Put shelter and settlements on the global agenda |
| Habitat II | 1996, Istanbul | The Habitat Agenda: adequate shelter for all and sustainable human settlements in an urbanising world | Shelter and local governance |
| Habitat III, New Urban Agenda (NUA) | 2016, Quito | Sustainable urban development through social inclusion and ending poverty, inclusive prosperity and opportunity, and environmentally sustainable, resilient growth | Current global urban framework, for about twenty years |
| Agenda 2030, SDG 11 | 2015, UN General Assembly | 17 goals; Goal 11: make cities and human settlements inclusive, safe, resilient and sustainable | Targets on housing, transport, participatory planning, heritage, disaster risk, green and public space |
| Paris Agreement | 2015 (COP21); in force 2016 | Hold warming well below 2 °C above pre-industrial levels and pursue 1.5 °C, through nationally determined contributions | Urban energy, buildings, transport and adaptation |
| Sendai Framework | 2015, Sendai | Disaster risk reduction for 2015–2030 | Risk-informed land use and resilient infrastructure |
Earlier milestones: the Stockholm Conference of 1972 (the first UN conference on the human environment), the Brundtland Report of 1987 (sustainable development as meeting present needs without compromising the ability of future generations to meet theirs) and the Rio Earth Summit of 1992 (Agenda 21, with Local Agenda 21 asking cities to draw up their own sustainability plans).
3. Planning as a State subject: the Seventh Schedule
Article 246 and the Seventh Schedule divide legislative power into the Union, State and Concurrent Lists. Town planning is not a named entry. Planning is a State matter because the State List holds the subjects it is built from, and the Union shapes it indirectly through the Concurrent List, national policy and funded schemes.
| List | Subject | Why it matters |
|---|---|---|
| State | Local government: municipal corporations, improvement trusts, district boards and other local authorities (Entry 5) | Creates and regulates urban local bodies and trusts |
| State | Public health and sanitation (Entry 6) | Sanitation, conservancy, hospitals |
| State | Land: rights in or over land, land tenures (Entry 18) | Tenure, land revenue and records |
| State | Taxes on lands and buildings (Entry 49) | Property tax, the main municipal tax base |
| Concurrent | Economic and social planning (Entry 20) | Plan-making by Centre and States |
| Concurrent | Acquisition and requisitioning of property (Entry 42) | Land acquisition law |
| Concurrent | Transfer of property other than agricultural land; registration of deeds and documents (Entry 6) | Sale, lease and registration |
| Union | Cantonments, railways, national highways, major ports, airports | Land and systems a State cannot plan alone |
On a Concurrent subject, a State law repugnant to a Union law is void to the extent of the conflict unless it has received the President’s assent (Article 254). So the Ministry of Housing and Urban Affairs and the Town and Country Planning Organisation (TCPO) advise, circulate model laws and guidelines, and fund missions; each State enacts its own planning law, and that is why the Acts differ.
4. The 73rd and 74th Amendments and the Twelfth Schedule
The 73rd and 74th Constitutional Amendment Acts (in force in April and June 1993) made local government a constitutional tier. The 73rd inserted Part IX (panchayats, Articles 243–243O) and the Eleventh Schedule of 29 matters. The 74th inserted Part IXA (Articles 243P–243ZG) and the Twelfth Schedule of 18 matters, for municipalities.
| Article | Provision |
|---|---|
| 243Q | Three types of municipality, notified by the Governor: Nagar Panchayat (area in transition from rural to urban), Municipal Council (smaller urban area), Municipal Corporation (larger urban area); factors include population, density, revenue, share of non-farm employment and economic importance |
| 243R | Seats filled by direct election from wards; persons with municipal knowledge may be nominated without a vote; State law may give MPs and MLAs membership |
| 243S | Wards Committees in municipalities with a population of three lakh or more |
| 243T | Reservation: SC and ST seats in proportion to population; not less than one-third of all seats, including the women’s share of SC/ST seats, for women; chairperson offices as State law provides |
| 243U | Five-year term; fresh election within six months of a dissolution |
| 243W | State law may endow municipalities with powers to prepare plans for economic development and social justice and to perform Twelfth Schedule functions |
| 243Y, 243ZA | State Finance Commission reviews municipal finances every five years; State Election Commission conducts municipal elections |
| 243ZD | District Planning Committee: consolidates panchayat and municipal plans into a draft district plan; at least four-fifths of members elected by and from the elected members of the district panchayat and the municipalities |
| 243ZE | Metropolitan Planning Committee for areas of ten lakh or more: draft development plan for the whole metropolitan area, including coordinated spatial planning; at least two-thirds of members elected by and from municipal councillors and panchayat chairpersons |
| Group | Matters |
|---|---|
| Planning and land | Urban planning including town planning (1); regulation of land-use and construction of buildings (2); planning for economic and social development (3) |
| Infrastructure and services | Roads and bridges (4); water supply for domestic, industrial and commercial purposes (5); public health, sanitation, conservancy and solid waste management (6); fire services (7); public amenities such as street lighting, parking lots, bus stops and public conveniences (17) |
| Environment and amenities | Urban forestry, protection of the environment and ecological aspects (8); parks, gardens, playgrounds (12); cultural, educational and aesthetic aspects (13) |
| Social and welfare | Safeguarding the interests of weaker sections, including persons with disabilities (9); slum improvement and upgradation (10); urban poverty alleviation (11) |
| Regulatory and civic | Burials and cremations (14); cattle pounds and prevention of cruelty to animals (15); vital statistics including registration of births and deaths (16); regulation of slaughter houses and tanneries (18) |
5. Town and Country Planning Acts and related laws
Planning law is State legislation, so each State has its own Act: a Town and Country Planning Act, a Regional and Town Planning Act or a Development Authority Act. The Bombay Town Planning Act, 1915 was India’s first planning statute and introduced the town planning scheme; later examples are the Delhi Development Act, 1957, the Maharashtra Regional and Town Planning Act, 1966 and the Gujarat Town Planning and Urban Development Act, 1976. TCPO circulated model planning laws to the States, the first in 1960 and a revised one in the 1980s, which States adopted in differing measure.
- Declare a planning or development area and constitute a planning or development authority.
- Survey, then prepare a regional or development plan; publish the draft, invite objections and suggestions, hear them and obtain State Government sanction. The sanctioned plan is statutory.
- Control development: none without permission. “Development” means carrying out building, engineering, mining or other operations in, on, over or under land, or making a material change in the use of any building or land.
- Provide implementation tools: town planning schemes or land pooling, acquisition, betterment levy and reservation of land for public purposes.
- Enforce and hear appeals: penalties, demolition of unauthorised development, appeals, and periodic review and revision of the plan.
Planning also meets other laws: the Environment (Protection) Act, 1986 with its impact-assessment and coastal regulation notifications; the Forest (Conservation) Act, 1980 (renamed in 2023 as the Van (Sanrakshan Evam Samvardhan) Adhiniyam); the Ancient Monuments and Archaeological Sites and Remains Act, 1958; the Real Estate (Regulation and Development) Act, 2016; and the Street Vendors (Protection of Livelihood and Regulation of Street Vending) Act, 2014. For the National Capital Region, the National Capital Region Planning Board Act, 1985 provides a Regional Plan to which the plans of the participating States are to conform.
6. Policies and programmes for planning in India
Because the Constitution leaves cities to the States, the Union steers through missions: centrally sponsored schemes that give money on conditions. When a programme appears in an exam, ask what it delivers, who selects the cities, and what the money is linked to.
| Programme | Purpose | Design logic |
|---|---|---|
| JNNURM (2005) | Better infrastructure and governance in selected cities, and basic services for the urban poor | Two main submissions: Urban Infrastructure and Governance, and Basic Services to the Urban Poor; each city prepares a City Development Plan and project reports; Centre, State and city sign a memorandum committing to reforms, so grants are reform-linked |
| Swachh Bharat Mission (Urban) (2014) | End open defecation; household, community and public toilets; solid waste management | Outcome-focused, with behaviour change and a city ranking; a second phase began in 2021 |
| Smart Cities Mission (2015) | Core infrastructure, a clean environment and a decent quality of life through smart solutions | Area-based development (retrofitting, redevelopment, greenfield) plus pan-city solutions; about 100 cities chosen by competition; each city implements through a Special Purpose Vehicle (SPV) |
| AMRUT (2015) | Basic urban services: water supply, sewerage and septage management, storm-water drainage, non-motorised transport, green space and parks | City-wide coverage in about 500 cities; State Annual Action Plans; service-level benchmarks and reforms; support for GIS-based master plans; a second phase, AMRUT 2.0, from 2021 |
| HRIDAY (2015) | Heritage-sensitive infrastructure and services in selected heritage cities | Heritage-city development plans, focused on the historic core and the amenities for residents and visitors |
| PMAY-U (2015) | “Housing for All” in urban areas | Four verticals: in-situ slum redevelopment using land as a resource, credit-linked subsidy, affordable housing in partnership, and beneficiary-led construction or enhancement |
| DAY-NULM | Urban livelihoods: skills, self-employment, support to street vendors, shelters for the urban homeless | Targets the incomes and shelter of the poor rather than assets; NULM began in 2013 and was renamed in 2016 |
National policies set direction: the National Urban Transport Policy (2006, favouring people over vehicles), the National Urban Housing and Habitat Policy (2007), the National Urban Sanitation Policy (2008), the National Mission on Sustainable Habitat (2008, under the National Action Plan on Climate Change) and the National Transit Oriented Development Policy (2017).
7. Types and hierarchy of plans
Plans form a hierarchy: each level fixes a frame inside which the next, more detailed level must fit. Going down, the area shrinks, the detail rises and the time horizon shortens.
| Plan | Area and horizon | Content | Status |
|---|---|---|---|
| Perspective plan | Whole settlement or region; long horizon, usually 20–25 years | Vision, goals, growth strategy and broad investment directions; not a land-use map | Mostly a non-statutory policy guide |
| Regional plan | District, metropolitan or inter-State region | Settlement pattern, regional land use, transport and utility networks, protected and natural areas | Statutory where the Act says so; the NCR Regional Plan under the NCRPB Act |
| Development plan (master plan) | Planning area of a city or town; about 20 years with periodic review | Land-use zoning, circulation, infrastructure, social facilities, density and development control regulations | Statutory, sanctioned by the State |
| Zonal or sector plan | One zone or sector of the city | Land use by parcel, local roads, facility sites and densities within the master-plan frame | Statutory or part of the plan, as the Act provides |
| Local area, layout and detailed plan | Neighbourhood, project or scheme; months to a few years | Plots, streets, open space, facilities and services; the basis for building permission | Sanctioned by the planning authority |
| Town planning scheme | A small area inside the planning area, where land is readjusted | Reconstituted plots, roads and amenities; largely self-financing | Statutory under the State Act |
| Annual plan | One year | Programme and budget: projects drawn from the plan, with phasing and finance | Executive and financial, not spatial |
Beyond spatial plans there are strategic and sector plans: the City Development Plan of JNNURM, comprehensive mobility plans, sanitation and disaster plans. They are not land-use plans but must be consistent with the development plan. After the 74th Amendment the Metropolitan Planning Committee prepares the draft development plan for a metropolitan area and the District Planning Committee consolidates the panchayat and municipal plans of its district.
- Base map and surveys, then analysis and projections.
- Goals and alternative proposals; choice of a preferred concept.
- Draft plan, public notice, objections and hearing; State sanction.
- Implementation by zoning, development control, projects and schemes; monitoring and periodic revision.
8. URDPFI, settlement classes and the logic of norms
URDPFI, the Urban and Regional Development Plans Formulation and Implementation Guidelines, 2014, issued by the Ministry of Urban Development with TCPO, replaced the UDPFI Guidelines of 1996. They are guidelines. They set out the types of plan and the plan-making process, planning for different geographies (hill, coastal, metropolitan and other regions), norms and standards, and implementation tools such as town planning schemes and land pooling. States adopt and adapt them; the National Building Code of the Bureau of Indian Standards and State building bye-laws govern the building itself.
Classification of settlements. Settlements are classed by population: small, medium and large towns, million-plus cities, metropolises and megacities. The class matters because plan type, facility standards and land-use mix depend on size. In the usual indicative structure, as a city grows the share of land for transport and communication rises and the residential share falls.
9. Land-use, facility and density arithmetic
Land-use norms are shares of the developed (developable) area, by the standard classes: residential, commercial, industrial, public and semi-public, recreational, transport and communication, and agriculture and water bodies. Deduct first the land that cannot or should not be developed (hills, water bodies, green belt, hazard zones), then apply the percentages. Worked example: planning area 5,000 ha; 30 per cent non-developable gives 3,500 ha developable; a residential norm of 40 per cent gives 1,400 ha and a commercial norm of 3 per cent gives 105 ha.
Facility norms give a population threshold per unit, an area per unit and a catchment radius, arranged by the planning-unit hierarchy: housing cluster, neighbourhood, community or sector, zone, city. A primary school and local shops serve a neighbourhood; a college or a hospital serves a zone or the city. Worked example: a 50 ha neighbourhood at a gross density of 300 persons/ha holds 15,000 people; with one dispensary per 5,000 people it needs 15,000/5,000 = 3 dispensaries; at 0.2 ha each that is 0.6 ha, 1.2 per cent of the neighbourhood.
Density. Gross density = population ÷ total area of the planned unit (plots, roads, open space and facilities). Net residential density = population ÷ area under residential use alone. Net is always the larger. If residential plots are 40 per cent of a layout and the gross density is 200 persons/ha, the net density is 200 ÷ 0.4 = 500 persons/ha.
Key takeaways
- Urbanisation is a rising urban share (level = U/P); urban growth is the rise in urban numbers. The level rises only if urban growth outpaces rural growth (URGD > 0), and reclassification adds to the urban count without migration.
- Census of India: statutory towns plus census towns (5,000 population, 75 per cent of male main workers non-agricultural, 400 persons/km²); Class I begins at one lakh.
- Athens 1933 (four functions) against Machu Picchu 1977 (its critique); Habitat I Vancouver 1976, II Istanbul 1996, III Quito 2016 (New Urban Agenda); SDG 11 for cities; Paris Agreement 2015.
- Planning is a State subject through local government, land and public health; the Union acts through the Concurrent List, TCPO and missions. The 74th Amendment gave Part IXA (243P–243ZG), the Twelfth Schedule of 18 matters, wards committees at three lakh, and DPC and MPC.
- Programmes: JNNURM is reform-linked; Smart Cities is area-based with an SPV; AMRUT is city-wide basic services; PMAY-U has four verticals; SBM-U is sanitation and waste.
- Plans run perspective, regional, development (statutory), zonal or sector, then layout and detailed, with an annual plan for money. URDPFI is guidance, not law; norms apply to the developable area; net density = gross density ÷ residential share.
Practice questions (20)
Attempt each one before opening the answer. Every explanation names the tempting wrong option as well as the right one, because that is where marks are lost.
Which set of conditions defines a census town in the Census of India?
Show answer
Answer: B — Population of at least 5,000, at least 75 per cent of male main workers in non-agricultural work, and a density of at least 400 persons per km²
The three Census tests are a population of at least 5,000, at least 75 per cent of male main workers in non-agricultural work, and a density of at least 400 persons per km². A place with a municipality is a statutory town whatever its size, so a municipal board is not a census-town test; and the variants with 50 per cent and 1,000 per km² mix in thresholds the Census does not use.The functional city of the Athens Charter (1933) was organised around which four functions?
Show answer
Answer: A — Dwelling, work, recreation and circulation
The Athens Charter of CIAM named dwelling, work, recreation (leisure) and circulation as the four functions of the city and asked that they be kept apart by zoning. The conservation variant is tempting because heritage features in later charters, but it is not one of the four.Which pairing of an international milestone with its main idea is correct?
Show answer
Answer: C — Charter of Machu Picchu (1977): a critique of the Athens Charter’s rigid separation of functions, asking for integrated, people-centred planning
Machu Picchu (1977) criticised Athens for ignoring people, culture and context. The New Urban Agenda came from Habitat III in Quito in 2016, not from Habitat I; the Habitat Agenda of adequate shelter for all came from Habitat II at Istanbul in 1996; and disaster risk reduction is the subject of the Sendai Framework, whereas the Paris Agreement is about climate. The Habitat III pairing is the tempting one because it mixes a real agenda with the wrong conference.Which of the following can raise the recorded urban population of a district between two censuses even if no one moves from a village to a town?
Show answer
Answer: A — Natural increase among existing urban residents; C — Reclassification of a large village as a census town; D — Extension of a municipal boundary to take in adjoining villages
Births over deaths in towns, reclassification of a village as a census town and a boundary extension all enlarge the urban count with no rural-to-urban movement. Return migration to villages does the opposite, lowering the urban population; it is the one item that does not raise it.Which of the following statements about the New Urban Agenda and related global mandates are correct?
Show answer
Answer: B — The New Urban Agenda was adopted at Habitat III in Quito in 2016; C — SDG 11 aims to make cities and human settlements inclusive, safe, resilient and sustainable; D — The Paris Agreement seeks to hold the rise in global temperature well below 2 °C above pre-industrial levels
The New Urban Agenda (Quito, 2016), SDG 11 and the Paris Agreement temperature goal are stated correctly. The Sendai Framework (2015–2030) is about disaster risk reduction, not housing finance.In 2001 a district had 4 lakh urban and 16 lakh rural residents; in 2011 it had 6 lakh urban and 18 lakh rural residents. The rise in its level of urbanisation, in percentage points, is ____.
Numerical answer — type the value.
Show answer
Answer: 5
Level in 2001 = 4/(4 + 16) = 20 per cent; level in 2011 = 6/(6 + 18) = 25 per cent; the rise is 5 percentage points. The urban population grew by 50 per cent, but that is urban growth, not the change in the level of urbanisation.A region’s total population grew from 25 lakh to 29 lakh between two censuses, while its urban population grew from 5 lakh to 7 lakh. Its urban–rural growth differential (urban growth rate minus rural growth rate), in percentage points, is ____.
Numerical answer — type the value.
Show answer
Answer: 30
Rural population = total − urban: 25 − 5 = 20 lakh, then 29 − 7 = 22 lakh. Urban growth = 2/5 = 40 per cent; rural growth = 2/20 = 10 per cent; URGD = 40 − 10 = 30 points. Using the total growth of 16 per cent in place of rural growth would give 24 instead.A town had a population of 1,75,000 in 2011 after a decadal growth of 40 per cent over 2001. Its population in 2001 was ____.
Numerical answer — type the value.
Show answer
Answer: 125000
P₂ = P₁(1 + g), so P₁ = 175000/1.4 = 125000. Subtracting 40 per cent of 175000 would give 105000, which is wrong because the growth was a percentage of the 2001 population, not of the 2011 one.Which statement best describes where the power to legislate on town planning lies under the Seventh Schedule?
Show answer
Answer: D — There is no separate entry; States legislate through local government, land and public health, and the Union acts through Concurrent subjects, policy and funds
The Seventh Schedule has no entry titled town planning. State power over local government (Entry 5), public health and sanitation (Entry 6) and land (Entry 18) carries it, while Concurrent entries such as economic and social planning and acquisition of property, together with funded missions, give the Union an indirect role. The 74th Amendment moved no Union entry to the States, and a Concurrent entry for planning would let Parliament override State Acts, which is not the position; a total bar on the Union is wrong because of the Concurrent subjects and the spending power.The Twelfth Schedule of the Constitution, linked to Article 243W, lists how many matters for municipalities, and which matter opens the list?
Show answer
Answer: C — 18 matters; urban planning including town planning
The Twelfth Schedule has 18 matters and opens with urban planning including town planning, followed by regulation of land-use and construction of buildings. The figure 29 belongs to the Eleventh Schedule for panchayats, which opens with agriculture; pairing 29 with urban planning mixes the two schedules.Which statement about the District Planning Committee (Article 243ZD) and the Metropolitan Planning Committee (Article 243ZE) is correct?
Show answer
Answer: B — At least four-fifths of a District Planning Committee and at least two-thirds of a Metropolitan Planning Committee are elected from the elected members of the local bodies concerned
The Constitution requires not less than four-fifths of a DPC and not less than two-thirds of an MPC to be elected by and from the elected members of the municipalities and panchayats concerned. The version with the fractions swapped is the usual slip; the committees are built on elected local representatives, not on nominated officials or legislators alone.Which of the following are provisions of Part IXA of the Constitution, inserted by the 74th Amendment?
Show answer
Answer: A — Wards Committees in municipalities with a population of three lakh or more; C — A State Election Commission to superintend and conduct municipal elections; D — A term of five years for a municipality, with fresh elections within six months of dissolution
Wards Committees (Article 243S), the State Election Commission (243ZA) and the five-year term with elections within six months of dissolution (243U) are all in Part IXA. Article 243W only permits a State to endow municipalities with Twelfth Schedule functions by law; nothing is transferred automatically.Which description matches the design of the Smart Cities Mission?
Show answer
Answer: A — Area-based development (retrofitting, redevelopment or greenfield) plus pan-city solutions, in cities chosen by competition and run through an SPV
Smart Cities Mission combines area-based development (retrofitting, redevelopment, greenfield) with pan-city smart solutions, selects about 100 cities by competition and has each implement through an SPV. The city-wide basic-services description is AMRUT, the reform-linked memorandum is JNNURM, and the subsidy and slum-redevelopment description is PMAY-U; the JNNURM description is the tempting one because both missions involve reforms.A State finds that most of its towns above one lakh population lack piped water, sewerage and storm drains. It wants every household in all of them covered, not a showcase district in a few cities. Which programme logic fits best?
Show answer
Answer: D — AMRUT-type city-wide basic services through State Annual Action Plans and service-level benchmarks, because the need is network coverage
The need is trunk and distribution networks across many towns, which is what a city-wide basic-services mission such as AMRUT is designed to fund, with State action plans and service-level benchmarks. Smart Cities concentrates resources on a selected area of a few cities and its pan-city solutions are mostly information systems layered on existing networks, so it does not provide universal pipes and drains, however modern it sounds.Which of the following were verticals of PMAY-U (Housing for All, 2015)?
Show answer
Answer: A — In-situ slum redevelopment using land as a resource; D — Beneficiary-led individual house construction or enhancement
The four verticals were in-situ slum redevelopment, a credit-linked subsidy, affordable housing in partnership and beneficiary-led construction or enhancement. Compulsory acquisition of vacant land resembles the old land-ceiling approach, and free serviced plots for every household was never a vertical.A city’s perspective plan, development plan and annual plan are compared. Which statement is correct?
Show answer
Answer: B — The perspective plan is long-range and usually non-statutory, the development plan carries legal force, and the annual plan turns projects into a one-year budget
The perspective plan is a long-horizon vision and strategy, normally a policy guide; the development plan, sanctioned under the State Act, is the document with legal force; and the annual plan is the short-range programme and budget, not a land-use map. Reversing the status of the first two is the usual error, and calling all three statutory land-use plans ignores that only the development plan and its zonal and layout detail are spatial and binding.A neighbourhood of 80 ha has a population of 16,000, and half of its area is under residential plots, the rest being roads, open space and facilities. Its gross density and net residential density, in persons per hectare, are respectively:
Show answer
Answer: A — 200 and 400
Gross density = 16,000/80 = 200 persons/ha. Residential area = 40 ha, so net residential density = 16,000/40 = 400 persons/ha. The reversed pair is tempting but impossible, because the net density is always at least the gross density.Which of the following are true of a statutory development plan under a State Town and Country Planning Act?
Show answer
Answer: A — It zones land use and carries development control regulations; B — Its draft is published and objections are heard before the State Government sanctions it; D — It can be reviewed and revised after sanction as the Act provides
A development plan zones land, carries development control rules, is sanctioned after notice, objections and hearing, and is reviewed periodically. It is State law and cannot bind another State’s authorities, since planning is a State subject.A planning area of 3,000 ha has 20 per cent of its land non-developable. The norm for residential use is 45 per cent of the developable area, and 10 per cent of the residential land is to be reserved for EWS housing. The residential land available for non-EWS housing, in ha, is ____.
Numerical answer — type the value.
Show answer
Answer: 972
Developable area = 3000 × 0.8 = 2400 ha; residential = 2400 × 0.45 = 1080 ha; EWS reserve = 108 ha; non-EWS residential = 1080 − 108 = 972 ha. Applying 45 per cent to the whole 3000 ha would wrongly give 1350 ha before the reserve.A neighbourhood of 60 ha is planned at a gross density of 300 persons/ha. The norm is one primary school per 4,500 people, each needing 0.4 ha, and one dispensary per 6,000 people, each needing 0.1 ha. The total land for primary schools and dispensaries, in ha, is ____.
Numerical answer — type the value.
Show answer
Answer: 1.9
Population = 60 × 300 = 18,000. Schools = 18,000/4,500 = 4, needing 4 × 0.4 = 1.6 ha. Dispensaries = 18,000/6,000 = 3, needing 3 × 0.1 = 0.3 ha. Total = 1.6 + 0.3 = 1.9 ha. Using the area of 60 ha as if it were the population would give nonsense, so convert area to people first.
