complexity of urban areas
B. Scarce resource
C. Health & Safety
D. Equity
E. Adaptability

G. Guidance

5. A. Interconnectedness and complexity
The ‘development process’ in urban areas has to be influenced by urban planning
because it has
interconnectedness and
complexity in its components.

6. A. Interconnectedness and complexity
today population is large and technology is complex
 producing many at the same time complex sectors (service, manufacturing &
industry, trade and urban agriculture)
This means
and decision in one sector affects many other sectors requiring urban planning
interventions.

7. A. Interconnectedness and complexity

Drive through (traffic)
Who lives in (housing)
Kind of jobs generated (economy)
Natural environment
Social Services
Education
health
Police
Fire protection
Recreation
Decision
to develop affects

8. A. Interconnectedness and complexity
The high level of
interconnectedness between different
sectors also require ‘systems that
span many communities urban
planning interventions.

9. B. Scarce resource
The market cannot be trusted to produce rational and
efficient land use system
Urban land is a scarce resource and needs stewardship
to balance the claim of one interest group against
another by urban planning.
This avoids economic, social, environmental and
physical chaos/disorder.

10. C. Health & Safety
Planning sets rules and standards
Limit overcrowding
Sets level for adequacy and capacity
of utilities (access to health institution,
pure water……)
construction regulations
Rules for environmental degradation

11. D. Equity
Planning sets the stage for equitable distribution
of resources which means it
Avoids privilege and exclusion between the
society /regardless of race, age, gender, social
status/ regarding access to urban resources
specially land /spatial inequalities

12. E. Adaptability
Establish regulations and controls to
adapt to urban development and its
consequences
E.g. adapting the new expansion
environment of the city because of
social disconnection like community
organization Idir, Mahiber, equb

13. F. Conflict resolution
Resolve conflicts between competing objectives and uses through control and
regulatory framework
E.g. the conflict between Residence and industries

14. G. Guidance
Direct the development
and growth of urban centers
in efficient way
‘a key role of the planning system is to
enable the provision of homes and
buildings, investment and jobs in
such a way which is consistent with
the principles of sustainable
development. It needs to be positive in
promoting competitiveness while being
protective towards the environment and
amenity.
(DTLR quoted in Syms Paul,2007)

15. 2. Urban Planning Classification

16. Urban planning classification
Terminologies
Statutory
Done or required by statute/ law
Zoning
To categorize by characteristics or use (Oxford Dictionaries,
2009)

17. Urban planning classification
Major planning type
A. Master planning (MP)
B. Structural planning (SP)
C. Strategic planning (St.P)
D. Local Development planning (LDP)

18. A. Master Plan
 Started in the early 1940s
 Grand/ large plans in scale
 In preparation few selected participate (elite based)
 It doesn’t give room for abuse/corruption.
 Are Static: difficult to change on demand
 Statutory /backed by law/
Addis Ababa Master plan(Greenery)

19. A. Master Plan
Comprehensive Planning of the urban physical pattern: Land
use ,road networks and transportation routes of cities
Three important factors of this planning type are
 Inclusion of all land area subject to the planning or
regulatory jurisdiction
 Inclusion of all subject matter related to the development
of the city
 A long time horizon above 20 years

20. B. Structural plan
Structural planning
 Also called ‘guide planning’ or ‘framework planning’
 is a framework to guide the future development including
land use patterns,
areas of open space,
infrastructure
transportation links
 socio-economic
 housing development
 urban redevelopment
 environmental
industry zone

21. B. Structural plan
Structural planning
Comprehensiveness; cover the whole area of the urban center
Long term perspective; contain time horizon(10-20 year)
Not static, Dynamic, Flexible can be updated on demand
Efficient, effective and realistic
Participation and equitable
LDP of Dejach Wube Sefer(Taye,2019)

22. B. Structural plan
Structural planning
Comprise one or more maps, plans or diagrammatic representations of the
proposed layout, features, character and links for areas
The maps or plans not detail
The maps, plans or representations are usually supported by text

23. C. Strategic planning
It is an instrument of managing changes through the following three steps
i. Diagnosis: Analysis the existing situation
ii. Vision: Identify where we wish to be in the future
iii. Strategies: How to get /arrive to the defined vision

24. C. Strategic planning
Realistic not idealistic
It plans the future
Adaptable to changes: modification
Participation, bargaining, share decision making
Includes not only physical planning but also urban development management
more typically 3-5 years

25. D. Local Development planning
 Statutory or non-statutory planning
 Deal with detail planning issues (2D/3D)
 zooms out the general structure plan
 Based on area specific policies such as:
a. upgrading,
b. renewal,
c. new land development and
d. conservation areas

26. D. Local Development planning
medium term development 5-10 years. It indicate
 Zoning the use types, building height and density
 Local streets and layout of basic infrastructure
 Organization of transportation system
 Housing typology and neighborhood organization
 Green space ,open space ,water bodies
 proposals of key socio-economic measures,
 Implementation strategies, regulations,
 Standards & norms LDP of Dejach Wube Sefer(Taye,2019)

27. What is City plan?
It is an instrument with which urban planning can
identify a decision and thus
intervene in the development process
It is an organized way of
Finding city’s needs
Creating vision
Setting goals and objectives

34. 3. Approaches to the city planning process

35. Approaches to the planning process
There are five approaches
1. Vision driven
2. Goal driven
3. Trend driven
4. Opportunity driven
5. Issue driven

36. Vision driven
• Setting overarching goal that controls the whole
process
• In preparing plans sticking to a single approaches
oversimplifies the planning process.
• Therefore it is important to blend two or more of the
approaches to meet specific planning needs

37. Goal driven
 Establishes long range goals
 The goals guide the rest of the planning process
 The goals based on public participation
 goals framed by planning body or governing body
 Establishing long range goals is complex requiring sophisticated
management

38. Trend driven
 Projecting population and land use trends in to future
 Use this projection for planning
 Technical not participatory
 Trends are not reliable they may change
 Thus not an ideal approach as core planning process
 Useful point of reference for other planning approaches

39. Opportunity driven
 Assessing future based on opportunities, strengths and constraints
 Based on citizen participation

40. Issue driven
 Identification of critical issues and focusing planning efforts
on these issues
 Broadly participatory
E.g supply of water vs electricity/road

41. 4. The planning process

42. The planning process
The planning process has four steps
A. Initial phase
B. Preliminary phase
C. Decision phase
D. Follow-up phase

43. A. Initial phase
 Decision to plan and commit resources
 Information gathering such as qualitative and quantitative inventory
/survey of
 land uses
 Infrastructure
 Economic base
 Population
 Natural environment

44. B. Preliminary phase
Identification of what changes should occur and what should stay the same
 Trend analysis / population, land use
 Problem identification
 Problem analysis
 SWOT analysis
 Development of goals and objectives
 Public involvement
Vision: set of ideas how the community should change

45. C. Decision Phase
 Identification of alternative solutions
 Selection of solution and plan of action
 Approval
 Implementation

46. D. Follow up Phase
 Monitoring and feedback
 Benchmarking/standared: setting measurable targets such as
• land supply,
• road improvement,
• number of jobs
 Assess the progress toward the benchmarks
 Adjustment of solution

47. Information resources for planning
Human resources
 Community volunteers tell us about realities of local situation
Published data
 Census results
• Population, family income, housing
 Health statistics: Births ,deaths etc
 Education
 Business activity
• Resources
• Environmental quality

48. Information resources for planning
Visual data
 Areal photographs
 Google earth maps
Base maps
 housing
 Land use
 Community facilities
 Transportation
 Flood prone areas
 Soils
 topography
