Landscape planning for urbanisation
All the world's cities are growing - and the quality of urban design
in the new areas is deeply depressing. In large measure the problem
results from entrusting the design of each component to specialists
- without any serious attention to design of the space between buildings
('the outdoor landscape'). Highway engineers design roads, builders
and architects design houses and apartment blocks, manufacturers design
industrial sheds. Then, at the end of the day, one might commission
a gardener to green-up the space between buildings, with ghastly results.
If you want your city to have good open space between buildings, and
on top of buildings, then landscape plans should precede urban development.
The principle applies on greenfield sites and in urban renewal and regeneration
projects.
Manifestly, we want access to clean air, sunshine, beautiful cities,
sparkling rivers, ancient woods, gathering places in which to encounter
other people. Landscape planners should focus on public goods and EID
(environmental impact design). They should be plural in spirit and forward-looking
in practice. This requires knowledge and information. With clear objectives
for guidance, as beacons guide ships, we can respond to contexts and
prepare plans which reflect the diverse wishes of diverse groups.
With imagination and skill, land uses can be integrated. Single-use
planning is generally bad planning. It causes side-effects and public
goods to be neglected, so that the land uses fall into disfavour and
then decay. In this chapter, I have aimed to take a long view of the
urbanisation process. While it proceeds, communities should found new
settlements which conserve the existing landscape and create new public
goods. Planning is required - but not too much of it.
At the start of the twentieth century, when optimistic reformers first
argued the case for 'planning', they were confident that state control
would produce a better world, with social justice, green parks, housing
set apart from industry, towns ringed by fields, sunny streets, dung-free
roads and hygienic disposal of other waste products. By the end of the
twentieth century, some of the dreams had been realised and others had
become nightmares. The new cities had dirty rivers, polluting roads,
dreary parks, ugly scenery and dangerous footpaths. The City of Dreadful
Night became the City of Dreadful Day.
Planning was part of the problem. In the Soviet Union, government planning
produced grim totalitarian cities dominated by wide roads and high blocks,
set far apart. In the United States, government planning took the form
of over-investment in roads, rigid land use zoning and under-investment
in public space. Western Europe compromised between these extremes,
keeping its ancient town centres but surrounding them with a mix of
Soviet and American planned development.
The author of London's best plan, Patrick Abercrombie, argued that:
When two or three buildings are gathered together, there arises the
question of their relationship to each other; when a road cuts across
an open stretch of country, there is its relation to the landscape;
when a piece of Land is enclosed, the question of the boundary lines
occurs, and the decision as to the use to which it is put or the manner
in which it is divided up. All these are examples of Town and Country
Planning (Abercrombie 1959 edn: 11).
Like other modernist planners, he was too hasty in arguing from some
to all. Twentieth century planning rested on an invalid argument form:
Some actions by land users affect other land users All actions which
affect other land users require planning Therefore all actions by land
users require planning
To logicians, this is known as the fallacy of the undistributed middle.
I prefer the following, valid, argument: Some actions by land users
affect public goods All actions which affect public goods require planning
Therefore some actions by landowners require planning
Landscape planning can produce settlements which are rich in public
goods. We should, as Nan Fairbrother said, make new landscapes for our
new lives (Fairbrother, 1970:8).
Urbanisation requires planning. Finding a good site is the hardest task.
Settlements need parents. Good decisions rely on good information. Topography
comes first. Heed the wisdom of the ancients! Parks rely on contexts.
Earthmoving provides great opportunities. Streams should be treasured.
owns need lakes. Towns need community forests. Roads can spoil towns.
'All public' is just as bad as 'all private'. Planning housing areas
for a single aspect of the public good tends to produce an unnacceptable
degree of uniformity. Planning commercial projects like fried eggs disregards
the public good. Noxious industries require special zones. Other types
of industry do not.
Public Open Space (POS)
Landscape planning and environmental impact design (EID) The physical
types of open space presently designed are astonishingly limited: the
swimming beach, the roadside picnic area, the woodland with "nature
trails", the grassed park dotted with trees and shrubbery, comprise
the conventional range. (Lynch 1972)
Great civilisations allocate open space to public and non-productive
uses. Historically, this has included gardens, temple compounds, ceremonial
grounds, outdoor markets, social places, gymnasia for exercise and recreation,
burial grounds, hunting and wildlife reserves. All this land is now
classified by planners as 'public open space', because the land is accessible
and unbuilt. It is a term which ignores the distinction between parks
and greenways. Parks are for protection [Fig 4.1]. Greenways are for
movement. The reasons for making 'public open space' are multifarious.
Lynch, as quoted above, was right to protest that 'the physical types
of open space presently designed are astonishingly limited'.
Public parks The park is dead. Long live the park.
Commons There always have been public rights in land and there always
should be. Municipal parks They were one of the great social inventions
of the nineteenth century. Squares and plazas Urban squares started
as markets and many should continue to have a commercial role. Public
gardens Cities need gardens and parks, not 'garks' Village greens Good
planning is more important than good design National parks in towns
Some parks need more-than-local funding. National parks in the country
Country areas of key importance to a nation should be given the protection
of national park status.
Private pleasure grounds Private enterprise is good at providing pleasure
Festival parks Nations love festivals, especially when they are in parks,
but the money will be squandered if an after-use is not planned before
the festival-use. Greenway function They should be 'green' in the environmental
sense and 'ways' in many senses. Greenway history and typology Ceremonial
avenues Boulevards Parkways Park belts Park systems Green belt Green
trails Environmental greenways Greenway character In terms of character,
greenways should have many colours. Open space management Greenways
can supervene on other land uses, like happiness on the face of youth.
A green web Public open space should radiate public goods.
