Facing Reality on a Finite Planet

I have written this in response to an article I read by Alan Berger, a landscape architect who co-directs the Norman B. Leventhal Center for Advanced Urbanism at MIT. The title was, “Cities Are Not as Big a Deal as You Think”.
He advocates an approach called “bioregionalism,” which treats cities and suburbs as a holistic system. The following are a few quotes from his article that have stimulated my response below.
1)      Seto says, “What’s very clear is that we need a language and a finer-grain differentiation of different types of urban life and urban ecosystems, …”

2)      “…for 50 years, people talked about suburbs as distinct from the city,” he says. But as cities and suburbs have changed and blurred together, that distinction no longer makes sense.
3)      Looking across the many different ways that countries define urban in the UN data, Seto says, “‘urban’ suggests a higher quality of life, higher standards of living, and more opportunity for the people who live there.” In developing countries particularly, urban denotes a place where people have access to jobs, running water, electricity, and other municipal services.
4)      That’s a much more basic definition of urbanity than a place with skyscrapers and subways. And when you think about “urban” in that context, it throws the spotlight on how many people are still not living with those basic amenities.
RESPONSE

Mr. Berger’s holistic system contains urban, suburban, and rural areas are that are phyla within a Built Domain that is expanding to accommodate growing populations. The expansion is forming a metastasizing pattern we refer to as sprawl across the face of a planet that is its source of life. Each phylum contains Shelter, Movement, Open Space, and Life Support Divisions in quantities that distinguish one from the other. The Shelter Division in all phyla is served by movement, open space, and life support; but the Movement Division is a servant that dominates its patrons.
Focusing on the distinction between urban, suburban, and rural areas overlooks the threat that is facing us. The Built Domain currently attempts to shelter growing populations in a sprawling, pathogenic pattern that is slowly consuming our source of life - The Natural Domain. In other words, there are two competing worlds on a single planet; and The Natural Domain does not compromise with ignorance. We have been given the responsibility to define symbiotic survival; and discussing the distinction among urban, suburban, and rural areas in the Built Domain overlooks the threat we can now see with satellite photography. I’m not arguing that the topics are irrelevant. In fact, our knowledge is extremely limited at the present time. I’m arguing that the results will produce tactical concepts without the adopted policy, strategy, and goals required to effectively battle an enemy that we refuse to acknowledge. Keep in mind that we were told to be fruitful and multiply at a time when it was a world without end, Amen.
I related to quote (1) because it seeks what I have produced for the Shelter Division of the Built Domain in three books over a lifetime of effort. These books have contributed the language and fine grain differentiation needed to guide the cellular contents of sprawl toward symbiotic solutions. My last book, The Science of City Design, needs to be reorganized and rewritten to simplify its message; but it contains everything needed to begin the search for intelligence that is the foundation for successful leadership direction. The reader could also benefit from a cloud-based collection of spreadsheet applications that would make the pages interactive and far more useful to research efforts.
Our traditional approach has focused on shelter, movement, open space, and life support projects. Our ability to survive and multiply is forcing us to focus on the aggregation of projects on a finite planet. Our leadership success to date is reflected by the sprawl and contamination we now contemplate from space. Our leadership ability will only improve when we recognize a threat and improve the language, policy, strategy, goals, objectives, and tactics adopted in response. It appears that our current strategy is to infect other host planets with parasitic policies that ignore symbiotic reality.

Elected and Appointed City Planning and Design Decisions


WHAT DO PLAN COMMISSION AND LOCAL ELECTED OFFICIALS KNOW ABOUT DEVELOPMENT?
– Pete Pointer

The question above has stimulated my response. The concept of reasonable men/women governing with opinion will continue to apply when there is limited knowledge to guide leadership decisions. The concept has been borrowed from a judicial system that has always struggled to replace opinion with science. City planning and design are in the same boat. These decisions affect populations and the planet but are based on popular, political, and special interest opinion. It’s like planning to free Europe and the Pacific Rim from tyranny in a town hall with no policy declaration, general staff, goals, intelligence, strategy, objectives, military training, or successful tactics; but with plenty of conflicting opinion and unrestrained behavior. Initiatives such as affordable housing, land use compatibility, bedroom suburbs, urban renewal, and so on are internal urban issues that have distracted attention from a threat that has only become visible with the use of satellite photography.  

The result of our focus on internal urban and suburban objectives has produced metastasizing sprawl across the face of our planet. Sprawl is a disease. It is a pathogenic product of limited awareness; and of mistaken opinion based on the belief that annexation is a solution to population growth on a world without end. Amen. It is a threat that requires an appropriate response based on a new scientific language and decision-making organization that can mobilize and correlate the diverse art and science interests involved. 

In my opinion, the only policy with enough scope to address sprawl will involve city planning and design that is capable of correlating the diverse interests associated with the production of shelter, movement, open space, and life support for growing populations within the urban and rural phyla of a Built Domain that is geographically limited to protect its source of life - The Natural Domain. In other words, the policy must become a declaration of symbiotic survival based on a new language and science of city design.

I have written two essays on my blog and on LinkedIn entitled, “The Least a Smart City Should Know” and “Open Space Metrics” for those interested in pursuing this train of thought.

Open Space Metrics


“Can the lessons of European squares be translated into metrics?”

Pete Pointer



Metrics will evolve from the measurement, comparison, and evaluation of many existing conditions when a consistent method of calculation is adopted. In my opinion, measurement must take the two and three-dimensional characteristics of any study area into account. I suggest that we look beneath appearance to begin with, and measure a project area in acres that includes the buildings surrounding the space. The entire set of measurements would include:



Total project area in sq. ft. and acres: TPA

Total building cover in sq. ft. and acres: BCA

Gross building area in sq. ft. and acres: GBA

Social pavement area in sq. ft. and acres: SOPA

Service pavement area in sq. ft. and acres: SEPA

Unpaved social open space in sq. ft. and acres: UPA



NOTE: In order to find gross building area around the piazza, all buildings would first be converted to building mass. (Mass is an imaginary envelope that encompasses all architectural detail.) Mass would be divided into horizontal slices at 12 foot or 3.658 meter vertical intervals. The area in each of these slices would be added to find gross building area. This includes the campanile.



The following calculations would be based on the previous measurements (SF=sq. ft.; AC=acres):



Shelter capacity SFAC = GBASF / TPAC

Shelter capacity percentage SFAC% = GBAC / TPAC

Impervious cover percentage IMP% = (BCAC + SOPAC + SEPAC) / TPAC

Intensity% = (GBAC + SEPAC) / TPAC



The intensity percentage suggested above is a simplified version of the universal intensity calculation I have suggested in my book. The formula for this intensity index is:



INT = SFAC * IMP% / 10,000



The equation says that the shelter intensity present in a project area, and imposed on a surrounding area, is equal to the shelter capacity in the project area times the impervious pavement percentage planned or present divided by 10,000. The use of 10,000 is introduced to make the universe of intensity options manageable and presentable in a single table of relative intensity. This table is included as Table 1.
