SP 2302 Planning Theory II
Level II – Semester 4
LECTURE 1
ORIGIN OF PLANNING PROCESS
Types of Planning Theory
Normative Planning Theory:
• Normative theories explain the city form in terms of norms and values
Planning Theory I
which had been followed by the people when they designed a city.
1. The Cosmic City Model
2. The Machine City Model
3. The Organic City Model
Substantive Planning Theory
• Explains the growth and development of cities.
• City as a historic process
• City as a people's production of spaces
• City as a socio-spatial process
• City as an economic center
Procedural Planning Theory
Planning Theory II
• Focuses on planning procedure.
• Procedural Planning theories explain how planning is done and the
planning process and how practice of planning should be done.
• Alternative approaches to planning
• Introduction to strategic planning
• Types of plans
• Policy framework for the convergence of local authority functions &
the plan
• Planning methodology as a systems view in integrated planning
ORIGIN OF PLANNING PROCESS
1. The story of the origin of planning process has to start with the
arrival of town planning to Sri Lanka.
2. The present formal town planning system of Sri Lanka arrived
during British rule, to address “URBAN PROBLEMS” such as
overcrowding, Poor Sanitation , Poverty, Health Problem, etc.
3. In order to address these problems, British imported 2 acts to Sri
Lanka.
1. Housing & Town Improvement Ordinance 1915
2. Town & Country Planning Ordinance1946 .
THE ARRIVAL OF TOWN PLANNING TO SRI LANKA
BRITISH RULE IN SRI LANKA [1815 – 1948]
• During British, Colombo had 3 Zones:
• Fort - British lived
• Pettah - Portuguese & Dutch lived
• Outer Pettah - Ceylonese lived
• Colombo Harbour was built in 1860s
Harbour
was built
• The fortifications were destroyed in 1860s
1869 to connect the Fort to the city.
Outer Pettah
• Due to lack of land within Fort, Britsh
Pettah
residences were shifted to Cinnamon Fort
Garden
THE ARRIVAL OF TOWN PLANNING TO SRI LANKA
BRITISH RULE IN SRI LANKA [1815 – 1948]
• Due to lack of land within Fort, Britsh
residences were shifted to Cinnamon
Garden
• High class British residences moved
to Kollupitya and Bambalapitiya
areas.
• The low income Ceylonese moved to
the old houses of British in Pettah and
Fort and railway warehouse Colombo Municipal
Council
(1865)
• “DECLINE OF PETTAH”

mentioned that,
“All cities should have a
Comprehensive Development Plan”
Accordingly, the below Development Plans are
made for Colombo city:
Patrick Geddes Plan – 1921
Clifford Holiday Plan – 1940
Patrick Abercrombie Plan – 1949 Colombo
Colombo Master Plan Project – 1978 Municipal Council
Colombo Metropolitan Regional Structure Plan (CMRSP) 1998 (1865)
City of Colombo Development Plan – 1999

Requirement for the Module:
Every one must have a soft copy or hard copy of any Development
Plan that is prepared at the Department (by the Senior Students for
their Academic Project)
Origin of Planning Process
Planning in 1940s & 1950s
Planning was concerned with the production of plans
which gave a detailed picture of a desired future in a
certain number of years.

Origin of Planning Process
Planning in 1960s -
British pioneer planner Patrick Geddes introduced a simple
sequence of action:
Survey Analysis Plan
The existing situation would be surveyed;
Analysis of the survey to find out the actions that needed to be taken;
The plan would embody these actions.
Planning in Late 1960s
Finding out the possible actions and evaluating them to find the
most suitable action.
This led to the Concept of Systems Planning
Origin of Planning Process
The Concept of Systems Planning
“Rather than producing new knowledge, it is important to
re-organize the existing knowledge”.
Cities were viewed as complex interacting systems .
(social, economic, biological and physical systems)
The different parts of the city system can be separated, and
the interactions between them can be analyzed.
Then, by introducing appropriate control mechanisms, the
behaviour of the city system can be altered in specific
ways, to achieve certain objectives.

BUT, ITS IMPORTANT TO UNDERSTAND THE SYSTEMS WORK AS
A WHOLE.
Origin of Planning Process
Planning Process
Based on this understanding,
the programmatic diagram of the planning process was set out
by three leading British planners of the Systems Planning :
Brian McLoughlin,
George Chadwick
Alan Wilson
Planning Process
Planning Process of Brian McLoughlin
Urban Planning: A Systems Approach
Planners need a practical framework for their actions.
Decision to adopt planning
Formulation of goals and objectives
Identification of possible actions to achieve
the goals and objectives
REVIEW
Evaluation of possible actions by reference
to costs/benefits
Selection and implementation of the most
suitable action through public investment

Strategy formulation
How do we collect data about a place?
• By visiting the place (Field Visits)
• Preliminary Visit
• Spending Full Day in the area
Primary Data
• Observe day and night activities
• By surveying and recording of field information
• About how the place functions?
• How the place is organized?
• Activity patterns, land uses, issues
• Casual discussion with local residents
Secondary Data
• By reviewing secondary sources about the place
• Resource Profile of the Place
• Historical records
• Previous development plans and projects
• Newspaper articles about issues
Collected data must be converted into SPATIAL INFORMATION
Pedestrian Movement Pattern
Collected data must be converted into SPATIAL INFORMATION
