This law establishes a hierarchical structure connecting units within a larger system. This is in keeping with some of the pioneering work around hierarchy theory at that time, such as Arthur Koestler\u2019s (1967) <em><span class=\"Body---Book-titles---italics\">The Ghost in the Machine<\/span>\u00a0<\/em> and Lancelot Law Whyte, Albert G. Wilson, and Donna Wilson (1969) (Editors) - <em><span class=\"Body---Book-titles---italics\">Hierarchical structures<\/span><\/em> .<\/p>\n<p class=\"Body\">Since the release of <span class=\"Body---Book-titles---italics\">Ekistics<\/span>, advances in knowledge around ecological systems, complexity theory and hierarchy theory have been more definitively applied to biological structures, as well as cities. These have served to substantiate Doxiadis\u2019 claims.<\/p>\n<p class=\"Body\">With respect to urban structure, nested hierarchies have been a particular focus. Nikos Salingaros, for example, cites <span class=\"Body---Book-titles---italics\">Hierarchy<\/span> as one of the eight interconnected rules or \u201cgeneric principles\u201d of urban form. He states that <em><span class=\"Body---Book-titles---italics\">Hierarchy<\/span><\/em> links many distinct elements at specific scales interdependently (another one of his rules): that is, the relationship is not symmetrical (<a href=\"#Law35\"><span class=\"Laws-highlight---italics--red\">Law 35<\/span><\/a>).<\/p>\n<p class=\"Body\">Salingaros is in good company, from Spiro Kostof who describes cities as \u201c\u2026.locked in an urban system, and urban hierarchy\u201d (Kostof, 1991, p. 38).\u00a0to N.J. Habraken who opens the discussion up to a variety of hierarchies related to settlement. These include, but are not limited to, hierarchies of circulation networks, enclosure, inclusion, and territory.<\/p>\n<p class=\"Body\">Also noteworthy is the work of Serge Salat, who suggests that, in order to create sustainable, resilient cities, three different types of hierarchies must be harmonized: \u201cThe hierarchies of built forms (urban blocks, neighbourhoods, districts, cities), the networks of communication, and the urban services connect these units on every scale and such human activities as living, working, commerce, education, and leisure from so many superimposed hierarchies\u201d (Salat, 2011, p. 29).<\/p>\n<p class=\"Body\">Since this idea a little abstract, a quick example is worth describing. Consider a situation where a town acts as the main centre of a set of lower order (smaller) settlements, while simultaneously serving a larger (higher order) city. NASA\u2019s <a href=\"https:\/\/www.nasa.gov\/mission_pages\/NPP\/news\/earth-at-night.html\"><em><span class=\"Body---Book-titles---italics\">View of the World at Night<\/span><\/em><\/a>, that clearly depicts clustered constellations of settlements, clearly shows these types of hierarchical relationships. Similarly, one could imagine a small, neighbourhood level shop existing at a \u201clower level\u201d than a regional distributor from which it gets its products.<\/p>\n<p class=\"References\">FURTHER READING (full citations found in <a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/back-matter\/bibliography\/\">reference list<\/a>):<\/p>\n\n<ul>\n \t<li><strong>Constantino Doxiadis<\/strong> - <em><span class=\"Body---Book-titles---italics\">Ekistics: An Introduction to the Science of Human Settlements<\/span><\/em><\/li>\n \t<li class=\"References---Bullets\"><strong>Arthur Koestler<\/strong> - <em><span class=\"Body---Book-titles---italics\">The Ghost in the Machine<\/span><\/em><\/li>\n \t<li class=\"References---Bullets\"><strong>Lancelot Law Whyte<\/strong>, <strong>Albert G.

It also presented the work of N.J. Habraken, Nikos Salingaros, and Serge Salat that speak to this concept. Doxiadis elaborates on this by recognizing that, given the complex nature of the co-dependent systems, settlements have a variety of connections \u201cin all directions.\u201d As such, there are a number of possible relationships between elements, some of which may not be hierarchical. This gets even more intricate when secondary and other forces (<a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/chapter\/lawsofsettlements_book_lod_2_development#Law11\"><span class=\"Laws-highlight---italics--red\">Law 11<\/span><\/a>) are considered. Despite the latter, Doxiadis states that generally speaking \u201cany organized activity should follow a pattern of hierarchical connections\u201d (Doxiadis, 1968, p. 307).<\/p>\n<p class=\"Body\">Of particular relevance to this law is Salingaros\u2019 discussion around another one of his \u201cgeneric principles of urban form,\u201d <em><span class=\"Body---Book-titles---italics\">Interdependence<\/span><\/em>. Described immediately after the principle of <em><span class=\"Body---Book-titles---italics\">Hierarchy<\/span><\/em> (<a href=\"#Law34\"><span class=\"Laws-highlight---italics--red\">Law 34<\/span><\/a>), he suggests that elements on different scales do not depend on one another symmetrically. That is, \u201ca higher scale requires all lower scales, but not vice versa.\u201d<\/p>\n<p class=\"Body\">Serge Salat, who builds on the insights of Salingaros, elaborates: \u201cA successful urban web is organized by an ordered fractal hierarchy of connections at different scales. It is connected in multiple ways without being chaotic.\u201d He adds, \u201dIf a hierarchical level is missing, the web is pathological. A hierarchy is often established over the course of history\u201d (Salat, 2011, p. 218). As implied in the latter, time is also a related and important factor (<a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/chapter\/lawsofsettlements_book_lod_2_development#Law14\"><span class=\"Laws-highlight---italics--red\">Law 14<\/span><\/a>).<\/p>\n<p class=\"References\">FURTHER READING (full citations found in <a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/back-matter\/bibliography\/\">reference list<\/a>):<\/p>\n\n<ul>\n \t<li><strong>Constantino Doxiadis<\/strong> - <em><span class=\"Body---Book-titles---italics\">Ekistics: An Introduction to the Science of Human Settlements<\/span><\/em><\/li>\n \t<li class=\"References---Bullets\"><strong>Nikos A.

Many often assume that the creation of a \u2018higher-level order\u2019 ultimately means the destruction of a lower level order, but this is not always the case. The introduction of larger neighbourhood\/regional supermarket, for example, does not necessarily lead to the destruction of all small markets. Although the number of lower order functions may diminish, each order has its own function relative to the scale it is a part of.<\/p>\n<p class=\"Body\">Local corner stores, therefore, serve the needs of inhabitants that cannot effectively be handled by stores or supermarkets located too far from their homes. Simply put: people can walk to them, and this prevents their elimination, despite the potentially elevated cost of products relative to larger regional retailers.<\/p>\n<p class=\"Body\">The birth of the modern supermarket is an interesting case in point, and Doxiadis highlights the fact that when they first appeared, two erred arguments arose. On one hand, advocates of the corner store and the \u201csmall scale\u201d opposed the larger supermarkets, describing them as inhuman. On the other, those in favour of the supermarkets denounced \u201csmall\u201d as obsolete in the face of the automobile city, seeking to eliminate them entirely.<\/p>\n<p class=\"Body\">As stated by Doxiadis, both perspectives were \u201cequally wrong, since there is a hierarchy of functions and communities, and the hierarchical system must function as a whole if the settlement is to function satisfactorily.\u201d<\/p>\n<p class=\"Body\">Even more relevant is the idea of a street hierarchy. The advent of the highway did not see the elimination of all street types below it, although many people tried to do so with unfortunate consequences. As stated by Serge Salat, the latter \u201cinvolved razing the old fabric and inordinately enlarging the urban grid to bring it in line with the major regional throughways. This was the position taken by Le Corbusier, modernism, and the new towns in Frances. We know today that this approach was a failure\u201d (Salat, 2011, p. 191).<\/p>\n<p class=\"Body\">Rare circumstances of large-scale destruction aside, most settlements saw highways simply add another level to the existing types of streets.<\/p>\n<p class=\"Body\">As an advocate of the \u201cfractal city,\u201d Nikos Salingaros\u2019 offers a more contemporary take on Doxiadis\u2019 insight: that settlements must have structural components of all sizes, across all scales, in order to remain healthy.<\/p>\n<p class=\"References\">FURTHER READING (full citations found in <a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/back-matter\/bibliography\/\">reference list<\/a>):<\/p>\n\n<ul>\n \t<li><strong>Constantino Doxiadis<\/strong> - <em><span class=\"Body---Book-titles---italics\">Ekistics: An Introduction to the Science of Human Settlements<\/span><\/em><\/li>\n \t<li class=\"References---Bullets\"><strong>Serge Salat<\/strong> - <em><span class=\"Body---Book-titles---italics\">Cities and Forms: On Sustainable Urbanism<\/span><\/em><\/li>\n \t<li class=\"References---Bullets\"><strong>Michael Southworth<\/strong> &amp; <strong>Eran Ben-Joseph<\/strong> - <em><span class=\"Body---Book-titles---italics\">Streets and the Shaping of Towns and Cities<\/span><\/em><\/li>\n \t<li class=\"References---Bullets\"><strong>Nikos A.

A simple comparison of the local corner store versus the larger neighbourhood\/regional supermarket was described, accordingly. However, in this law, Doxiadis elaborates further by stating that cost-distance and time-distance are important factors contributing to the satisfaction of the inhabitants.<\/p>\n<p class=\"Body\">The role of both of these factors has been analyzed and developed further since the publication of <span class=\"Body---Book-titles---italics\">Ekistics<\/span>. As described within the <em><span style=\"text-decoration: underline\"><span class=\"Body---Book-titles---italics\">Planning and Urban Design Standards<\/span><\/span><\/em>, cost-distance\u2014as opposed to Euclidean distances measured in straight or curved paths\u2014measures distance that \u201cinvolves the least effort in moving across a surface\u201d (American Planning Association, 2007, p. 334). This has been much easier to measure with the development of <a href=\"https:\/\/en.wikipedia.org\/wiki\/Geographic_information_system\">Geographic Information System<\/a> (GIS) softwares that readily allow these calculations.<\/p>\n<p class=\"Body\">Time-distance measures, on the other hand, look at the time required to cross certain distances. These have become particularly important for the management of constructions (tunnels, bridges, etc.) as well as transit travel (i.e. transport schedules representing bus locations along transit routes).<\/p>\n<p class=\"Body\">As eloquently described by Jarrett Walker in <em><span style=\"text-decoration: underline\"><span class=\"Body---Book-titles---italics\">Human Transit<\/span><\/span><\/em>, it is worth mentioning that, although travel times are important for good transit design\u2014and are often cited for proposed transit lines\u2014the issue of frequency is equally critical.<\/p>\n<p class=\"Body\">The uses of both types of measures aside, it is clear that each continues to play an important role in shaping the distribution of activities, uses and spaces within a settlement.<\/p>\n<p class=\"References\">FURTHER READING (full citations found in <a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/back-matter\/bibliography\/\">reference list<\/a>):<\/p>\n\n<ul>\n \t<li><strong>Constantino Doxiadis<\/strong> - <em><span class=\"Body---Book-titles---italics\">Ekistics: An Introduction to the Science of Human Settlements<\/span><\/em><\/li>\n \t<li class=\"References---Bullets\"><strong>American Planning Association<\/strong>, <strong>Frederick R.

To start, in order to better understand the intent of this law, the term \u201cphysical texture\u201d must be defined. Interestingly, Doxiadis failed to provide a specific explanation of the term within <span class=\"Body---Book-titles---italics\">Ekistics<\/span>. Instead, he alluded to it by explaining \u201ctextural forces\u201d that acted on human settlements. Within his book, \u201cphysical texture\u201d referred to the spatial relationships and distribution of physical elements across the terrain.<\/p>\n<p class=\"Body\">Although it is not described as such, the idea of physical texture is related to the idea of a settlement\u2019s \u201cgrain\u201d\u2014something that has a more targeted definition. Described by Kevin Lynch as one of the four basic aspects of physical form (alongside <span class=\"Body---Book-titles---italics\">size, density<\/span>, and <span class=\"Body---Book-titles---italics\">shape<\/span>), <span class=\"Body---Book-titles---italics\">grain<\/span> is typically divided into fine and coarse. The former refers to settlement fabrics that have smaller blocks, narrower buildings and, hence, sharper (\u201cfiner\u201d) divisions. In contrast, the latter refers to environments that have broader, larger-scale differences. Think medieval towns (fine grain) versus typical North American suburbs (coarse grain).<\/p>\n<p class=\"Body\">Given that settlements range in size\u2014from villages to large cities\u2014grain can only be measured across specific scales, with larger settlements being composed of neighbourhoods of varying grain, for example. As such, Doxiadis\u2019 \u201cphysical texture\u201d of a settlement refers to the mix of fine and coarse grain elements.<\/p>\n<p class=\"Body\">With this in mind, Doxiadis suggests that a settlement\u2019s physical texture is dependent on its scale (neighbourhood, town, metropolis, etc.) as well as the smaller component (what he calls <span class=\"Body---Book-titles---italics\">Ekistic modulus<\/span>) from which is it logically composed. This is best described through an example: a house (the scalar unit) is composed of rooms (smaller component). So, large rooms beget large houses. Similarly, Doxiadis puts forth the idea that small cities are composed of city blocks and, if the latter is large, the texture of this city is large.<\/p>\n<p class=\"Body\">Interestingly, he also notes that the smaller component is, itself, dynamic in response to the scale of the settlement. So, if a small city grows to a large city, its city block component gets too small to define its texture, requiring a corresponding jump to groups of blocks or \u201csuperblocks\u201d.<\/p>\n<p class=\"Body\">Clearly, a certain degree of subjective judgment is required to define what constitutes the proper smaller component unit relative to the scale of settlement. This is addressed a little more in <a href=\"#Law39\"><span class=\"Laws-highlight---italics--red\">Law 39<\/span><\/a>. However, the idea that the texture of settlement is based on the dynamic interaction of scale and smaller component units remains powerful when thinking about the structure of a built environment. It also reminds us of Anne Vernez Moudon\u2019s insights highlighted in<a href=\"#Law33\"> <span class=\"Laws-highlight---italics--red\">Law 33<\/span><\/a>: that the building\/house is a basic cell of the city while the lot is basic cell of the neighbourhood.<\/p>\n<p class=\"References\">FURTHER READING (full citations found in <a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/back-matter\/bibliography\/\">reference list<\/a>):<\/p>\n\n<ul>\n \t<li><strong>Constantino Doxiadis<\/strong> - <em><span class=\"Body---Book-titles---italics\">Ekistics: An Introduction to the Science of Human Settlements<\/span><\/em><\/li>\n \t<li class=\"References---Bullets\"><strong>Kevin Lynch<\/strong> - \u201c<em>The Form of Cities<\/em>\u201c, From Scientific American 190, no 4., 1954<\/li>\n \t<li class=\"References---Bullets\"><strong>Yuri Artibise<\/strong> - <em><span class=\"Body---Book-titles---italics\">Urban Fabric: The Form of Cities<\/span><\/em> - <a href=\"http:\/\/yuriartibise.com\/urban-fabric\/\"><span class=\"Link-blue\">http:\/\/yuriartibise.com\/urban-fabric\/<\/span><\/a><\/li>\n \t<li class=\"References---Bullets\"><strong>Anne Vernez Moudon<\/strong> - <em><span class=\"Body---Book-titles---italics\">Built for Change: Neighbourhood Architecture in San Francisco<\/span><\/em><\/li>\n<\/ul>\n<h1 id=\"toc_marker-5-4-8\" class=\"Law-\"><strong><span class=\"Law-Number\"><a id=\"Law39\" href=\"\"><\/a>39.<\/span> The texture of a human settlement changes as its dimensions change.<\/strong><\/h1>\n<p class=\"Body\">The major contributors as to what defines the texture of a settlement\u2014scale and its smaller component unit\u2014were addressed in <span class=\"Laws-highlight---italics--red\">Law 38<\/span>. But as discussed, the choice of the \u201csmaller unit\u201d was left open. This law addresses the latter in a more definitive way as Doxiadis describes how the house, a group of houses or city block may be a good unit for the texture of a small city. For larger cities, however, these units are too small and therefore require reconsideration. He states: \u201cThe texture of larger human settlements should change when the population of a settlement grows from say 100,000 to one million, since the settlement is unable to operate efficiently with a texture of small blocks\u201d (Doxiadis, <span class=\"Body---Book-titles---italics\">1968, p. 309<\/span><span style=\"text-decoration: underline\"><span class=\"Body---Book-titles---italics\">).<\/span><\/span><\/p>\n<p class=\"Body\">He continues, describing that in order for settlements to remain healthy, they must reshape themselves accordingly, adjusting to the new conditions. The addition of new major arteries to allow for more efficient flows of people and goods through the settlement is an example of how a settlement might accommodate growth and change. According to Doxiadis, a failure to evolve and transform\u2014via its own inertia (<a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/chapter\/lawsofsettlements_book_lod_3_extinction#Law19\"><span class=\"Laws-highlight---italics--red\">Law 19<\/span><\/a>)\u2014results in an inappropriate texture.<\/p>\n<p class=\"Body\">Anthony E.J. Morris\u2019 historical description of ancient Rome in <em><span style=\"text-decoration: underline\"><span class=\"Body---Book-titles---italics\">History of Urban Form Before the Industrial Revolution<\/span><\/span><\/em> speaks well to this issue, as he highlights the struggles inherent to the functioning of a city that was born from the growth of the small villages that coalesced into a single urban area across lower terrain. Citing challenges including increased flooding, disease and pollution, he points out that Roman planners, architects and engineers were constantly struggling to cope with the city\u2019s natural and historical context. He states: \u201cAdd to these natural problems the planning constraints that resulted from preceding generations\u2019 attempts to overcome them\u2026and it is by no means surprising that ancient Rome, like so many large modern urban centres, was incapable of being comprehensively restructured.

This law establishes a hierarchical structure connecting units within a larger system. This is in keeping with some of the pioneering work around hierarchy theory at that time, such as Arthur Koestler\u2019s (1967) <em><span class=\"Body---Book-titles---italics\">The Ghost in the Machine<\/span>\u00a0<\/em> and Lancelot Law Whyte, Albert G.

These have served to substantiate Doxiadis\u2019 claims.<\/p>\n<p class=\"Body\">With respect to urban structure, nested hierarchies have been a particular focus. Nikos Salingaros, for example, cites <span class=\"Body---Book-titles---italics\">Hierarchy<\/span> as one of the eight interconnected rules or \u201cgeneric principles\u201d of urban form. He states that <em><span class=\"Body---Book-titles---italics\">Hierarchy<\/span><\/em> links many distinct elements at specific scales interdependently (another one of his rules): that is, the relationship is not symmetrical (<a href=\"#Law35\"><span class=\"Laws-highlight---italics--red\">Law 35<\/span><\/a>).<\/p>\n<p class=\"Body\">Salingaros is in good company, from Spiro Kostof who describes cities as \u201c\u2026.locked in an urban system, and urban hierarchy\u201d (Kostof, 1991, p. 38).\u00a0to N.J. Habraken who opens the discussion up to a variety of hierarchies related to settlement. These include, but are not limited to, hierarchies of circulation networks, enclosure, inclusion, and territory.<\/p>\n<p class=\"Body\">Also noteworthy is the work of Serge Salat, who suggests that, in order to create sustainable, resilient cities, three different types of hierarchies must be harmonized: \u201cThe hierarchies of built forms (urban blocks, neighbourhoods, districts, cities), the networks of communication, and the urban services connect these units on every scale and such human activities as living, working, commerce, education, and leisure from so many superimposed hierarchies\u201d (Salat, 2011, p. 29).<\/p>\n<p class=\"Body\">Since this idea a little abstract, a quick example is worth describing. Consider a situation where a town acts as the main centre of a set of lower order (smaller) settlements, while simultaneously serving a larger (higher order) city.

It also presented the work of N.J. Habraken, Nikos Salingaros, and Serge Salat that speak to this concept. Doxiadis elaborates on this by recognizing that, given the complex nature of the co-dependent systems, settlements have a variety of connections \u201cin all directions.\u201d As such, there are a number of possible relationships between elements, some of which may not be hierarchical. This gets even more intricate when secondary and other forces (<a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/chapter\/lawsofsettlements_book_lod_2_development#Law11\"><span class=\"Laws-highlight---italics--red\">Law 11<\/span><\/a>) are considered. Despite the latter, Doxiadis states that generally speaking \u201cany organized activity should follow a pattern of hierarchical connections\u201d (Doxiadis, 1968, p. 307).<\/p>\n<p class=\"Body\">Of particular relevance to this law is Salingaros\u2019 discussion around another one of his \u201cgeneric principles of urban form,\u201d <em><span class=\"Body---Book-titles---italics\">Interdependence<\/span><\/em>. Described immediately after the principle of <em><span class=\"Body---Book-titles---italics\">Hierarchy<\/span><\/em> (<a href=\"#Law34\"><span class=\"Laws-highlight---italics--red\">Law 34<\/span><\/a>), he suggests that elements on different scales do not depend on one another symmetrically. That is, \u201ca higher scale requires all lower scales, but not vice versa.\u201d<\/p>\n<p class=\"Body\">Serge Salat, who builds on the insights of Salingaros, elaborates: \u201cA successful urban web is organized by an ordered fractal hierarchy of connections at different scales. It is connected in multiple ways without being chaotic.\u201d He adds, \u201dIf a hierarchical level is missing, the web is pathological. A hierarchy is often established over the course of history\u201d (Salat, 2011, p. 218). As implied in the latter, time is also a related and important factor (<a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/chapter\/lawsofsettlements_book_lod_2_development#Law14\"><span class=\"Laws-highlight---italics--red\">Law 14<\/span><\/a>).<\/p>\n<p class=\"References\">FURTHER READING (full citations found in <a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/back-matter\/bibliography\/\">reference list<\/a>):<\/p>\n<ul>\n<li><strong>Constantino Doxiadis<\/strong> &#8211; <em><span class=\"Body---Book-titles---italics\">Ekistics: An Introduction to the Science of Human Settlements<\/span><\/em><\/li>\n<li class=\"References---Bullets\"><strong>Nikos A.

Many often assume that the creation of a \u2018higher-level order\u2019 ultimately means the destruction of a lower level order, but this is not always the case. The introduction of larger neighbourhood\/regional supermarket, for example, does not necessarily lead to the destruction of all small markets. Although the number of lower order functions may diminish, each order has its own function relative to the scale it is a part of.<\/p>\n<p class=\"Body\">Local corner stores, therefore, serve the needs of inhabitants that cannot effectively be handled by stores or supermarkets located too far from their homes. Simply put: people can walk to them, and this prevents their elimination, despite the potentially elevated cost of products relative to larger regional retailers.<\/p>\n<p class=\"Body\">The birth of the modern supermarket is an interesting case in point, and Doxiadis highlights the fact that when they first appeared, two erred arguments arose. On one hand, advocates of the corner store and the \u201csmall scale\u201d opposed the larger supermarkets, describing them as inhuman. On the other, those in favour of the supermarkets denounced \u201csmall\u201d as obsolete in the face of the automobile city, seeking to eliminate them entirely.<\/p>\n<p class=\"Body\">As stated by Doxiadis, both perspectives were \u201cequally wrong, since there is a hierarchy of functions and communities, and the hierarchical system must function as a whole if the settlement is to function satisfactorily.\u201d<\/p>\n<p class=\"Body\">Even more relevant is the idea of a street hierarchy. The advent of the highway did not see the elimination of all street types below it, although many people tried to do so with unfortunate consequences. As stated by Serge Salat, the latter \u201cinvolved razing the old fabric and inordinately enlarging the urban grid to bring it in line with the major regional throughways. This was the position taken by Le Corbusier, modernism, and the new towns in Frances. We know today that this approach was a failure\u201d (Salat, 2011, p. 191).<\/p>\n<p class=\"Body\">Rare circumstances of large-scale destruction aside, most settlements saw highways simply add another level to the existing types of streets.<\/p>\n<p class=\"Body\">As an advocate of the \u201cfractal city,\u201d Nikos Salingaros\u2019 offers a more contemporary take on Doxiadis\u2019 insight: that settlements must have structural components of all sizes, across all scales, in order to remain healthy.<\/p>\n<p class=\"References\">FURTHER READING (full citations found in <a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/back-matter\/bibliography\/\">reference list<\/a>):<\/p>\n<ul>\n<li><strong>Constantino Doxiadis<\/strong> &#8211; <em><span class=\"Body---Book-titles---italics\">Ekistics: An Introduction to the Science of Human Settlements<\/span><\/em><\/li>\n<li class=\"References---Bullets\"><strong>Serge Salat<\/strong> &#8211; <em><span class=\"Body---Book-titles---italics\">Cities and Forms: On Sustainable Urbanism<\/span><\/em><\/li>\n<li class=\"References---Bullets\"><strong>Michael Southworth<\/strong> &amp; <strong>Eran Ben-Joseph<\/strong> &#8211; <em><span class=\"Body---Book-titles---italics\">Streets and the Shaping of Towns and Cities<\/span><\/em><\/li>\n<li class=\"References---Bullets\"><strong>Nikos A.

A simple comparison of the local corner store versus the larger neighbourhood\/regional supermarket was described, accordingly. However, in this law, Doxiadis elaborates further by stating that cost-distance and time-distance are important factors contributing to the satisfaction of the inhabitants.<\/p>\n<p class=\"Body\">The role of both of these factors has been analyzed and developed further since the publication of <span class=\"Body---Book-titles---italics\">Ekistics<\/span>. As described within the <em><span style=\"text-decoration: underline\"><span class=\"Body---Book-titles---italics\">Planning and Urban Design Standards<\/span><\/span><\/em>, cost-distance\u2014as opposed to Euclidean distances measured in straight or curved paths\u2014measures distance that \u201cinvolves the least effort in moving across a surface\u201d (American Planning Association, 2007, p. 334). This has been much easier to measure with the development of <a href=\"https:\/\/en.wikipedia.org\/wiki\/Geographic_information_system\">Geographic Information System<\/a> (GIS) softwares that readily allow these calculations.<\/p>\n<p class=\"Body\">Time-distance measures, on the other hand, look at the time required to cross certain distances. These have become particularly important for the management of constructions (tunnels, bridges, etc.) as well as transit travel (i.e. transport schedules representing bus locations along transit routes).<\/p>\n<p class=\"Body\">As eloquently described by Jarrett Walker in <em><span style=\"text-decoration: underline\"><span class=\"Body---Book-titles---italics\">Human Transit<\/span><\/span><\/em>, it is worth mentioning that, although travel times are important for good transit design\u2014and are often cited for proposed transit lines\u2014the issue of frequency is equally critical.<\/p>\n<p class=\"Body\">The uses of both types of measures aside, it is clear that each continues to play an important role in shaping the distribution of activities, uses and spaces within a settlement.<\/p>\n<p class=\"References\">FURTHER READING (full citations found in <a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/back-matter\/bibliography\/\">reference list<\/a>):<\/p>\n<ul>\n<li><strong>Constantino Doxiadis<\/strong> &#8211; <em><span class=\"Body---Book-titles---italics\">Ekistics: An Introduction to the Science of Human Settlements<\/span><\/em><\/li>\n<li class=\"References---Bullets\"><strong>American Planning Association<\/strong>, <strong>Frederick R.

To start, in order to better understand the intent of this law, the term \u201cphysical texture\u201d must be defined. Interestingly, Doxiadis failed to provide a specific explanation of the term within <span class=\"Body---Book-titles---italics\">Ekistics<\/span>. Instead, he alluded to it by explaining \u201ctextural forces\u201d that acted on human settlements. Within his book, \u201cphysical texture\u201d referred to the spatial relationships and distribution of physical elements across the terrain.<\/p>\n<p class=\"Body\">Although it is not described as such, the idea of physical texture is related to the idea of a settlement\u2019s \u201cgrain\u201d\u2014something that has a more targeted definition. Described by Kevin Lynch as one of the four basic aspects of physical form (alongside <span class=\"Body---Book-titles---italics\">size, density<\/span>, and <span class=\"Body---Book-titles---italics\">shape<\/span>), <span class=\"Body---Book-titles---italics\">grain<\/span> is typically divided into fine and coarse. The former refers to settlement fabrics that have smaller blocks, narrower buildings and, hence, sharper (\u201cfiner\u201d) divisions. In contrast, the latter refers to environments that have broader, larger-scale differences. Think medieval towns (fine grain) versus typical North American suburbs (coarse grain).<\/p>\n<p class=\"Body\">Given that settlements range in size\u2014from villages to large cities\u2014grain can only be measured across specific scales, with larger settlements being composed of neighbourhoods of varying grain, for example. As such, Doxiadis\u2019 \u201cphysical texture\u201d of a settlement refers to the mix of fine and coarse grain elements.<\/p>\n<p class=\"Body\">With this in mind, Doxiadis suggests that a settlement\u2019s physical texture is dependent on its scale (neighbourhood, town, metropolis, etc.) as well as the smaller component (what he calls <span class=\"Body---Book-titles---italics\">Ekistic modulus<\/span>) from which is it logically composed. This is best described through an example: a house (the scalar unit) is composed of rooms (smaller component). So, large rooms beget large houses. Similarly, Doxiadis puts forth the idea that small cities are composed of city blocks and, if the latter is large, the texture of this city is large.<\/p>\n<p class=\"Body\">Interestingly, he also notes that the smaller component is, itself, dynamic in response to the scale of the settlement. So, if a small city grows to a large city, its city block component gets too small to define its texture, requiring a corresponding jump to groups of blocks or \u201csuperblocks\u201d.<\/p>\n<p class=\"Body\">Clearly, a certain degree of subjective judgment is required to define what constitutes the proper smaller component unit relative to the scale of settlement. This is addressed a little more in <a href=\"#Law39\"><span class=\"Laws-highlight---italics--red\">Law 39<\/span><\/a>. However, the idea that the texture of settlement is based on the dynamic interaction of scale and smaller component units remains powerful when thinking about the structure of a built environment. It also reminds us of Anne Vernez Moudon\u2019s insights highlighted in<a href=\"#Law33\"> <span class=\"Laws-highlight---italics--red\">Law 33<\/span><\/a>: that the building\/house is a basic cell of the city while the lot is basic cell of the neighbourhood.<\/p>\n<p class=\"References\">FURTHER READING (full citations found in <a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/back-matter\/bibliography\/\">reference list<\/a>):<\/p>\n<ul>\n<li><strong>Constantino Doxiadis<\/strong> &#8211; <em><span class=\"Body---Book-titles---italics\">Ekistics: An Introduction to the Science of Human Settlements<\/span><\/em><\/li>\n<li class=\"References---Bullets\"><strong>Kevin Lynch<\/strong> &#8211; \u201c<em>The Form of Cities<\/em>\u201c, From Scientific American 190, no 4., 1954<\/li>\n<li class=\"References---Bullets\"><strong>Yuri Artibise<\/strong> &#8211; <em><span class=\"Body---Book-titles---italics\">Urban Fabric: The Form of Cities<\/span><\/em> &#8211; <a href=\"http:\/\/yuriartibise.com\/urban-fabric\/\"><span class=\"Link-blue\">http:\/\/yuriartibise.com\/urban-fabric\/<\/span><\/a><\/li>\n<li class=\"References---Bullets\"><strong>Anne Vernez Moudon<\/strong> &#8211; <em><span class=\"Body---Book-titles---italics\">Built for Change: Neighbourhood Architecture in San Francisco<\/span><\/em><\/li>\n<\/ul>\n<h1 id=\"toc_marker-5-4-8\" class=\"Law-\"><strong><span class=\"Law-Number\"><a id=\"Law39\" href=\"\"><\/a>39.<\/span> The texture of a human settlement changes as its dimensions change.<\/strong><\/h1>\n<p class=\"Body\">The major contributors as to what defines the texture of a settlement\u2014scale and its smaller component unit\u2014were addressed in <span class=\"Laws-highlight---italics--red\">Law 38<\/span>. But as discussed, the choice of the \u201csmaller unit\u201d was left open. This law addresses the latter in a more definitive way as Doxiadis describes how the house, a group of houses or city block may be a good unit for the texture of a small city. For larger cities, however, these units are too small and therefore require reconsideration. He states: \u201cThe texture of larger human settlements should change when the population of a settlement grows from say 100,000 to one million, since the settlement is unable to operate efficiently with a texture of small blocks\u201d (Doxiadis, <span class=\"Body---Book-titles---italics\">1968, p. 309<\/span><span style=\"text-decoration: underline\"><span class=\"Body---Book-titles---italics\">).<\/span><\/span><\/p>\n<p class=\"Body\">He continues, describing that in order for settlements to remain healthy, they must reshape themselves accordingly, adjusting to the new conditions. The addition of new major arteries to allow for more efficient flows of people and goods through the settlement is an example of how a settlement might accommodate growth and change. According to Doxiadis, a failure to evolve and transform\u2014via its own inertia (<a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/chapter\/lawsofsettlements_book_lod_3_extinction#Law19\"><span class=\"Laws-highlight---italics--red\">Law 19<\/span><\/a>)\u2014results in an inappropriate texture.<\/p>\n<p class=\"Body\">Anthony E.J. Morris\u2019 historical description of ancient Rome in <em><span style=\"text-decoration: underline\"><span class=\"Body---Book-titles---italics\">History of Urban Form Before the Industrial Revolution<\/span><\/span><\/em> speaks well to this issue, as he highlights the struggles inherent to the functioning of a city that was born from the growth of the small villages that coalesced into a single urban area across lower terrain. Citing challenges including increased flooding, disease and pollution, he points out that Roman planners, architects and engineers were constantly struggling to cope with the city\u2019s natural and historical context. He states: \u201cAdd to these natural problems the planning constraints that resulted from preceding generations\u2019 attempts to overcome them\u2026and it is by no means surprising that ancient Rome, like so many large modern urban centres, was incapable of being comprehensively restructured. At best, there could only be piecemeal \u2018town-patching\u2019 measures\u201d (Morris, 1979, p. 42).<\/p>\n<p class=\"Body\">As a counterpoint to Rome, Georges-Eug\u00e8ne Haussman\u2019s radical reorganization of Paris\u2019 urban fabric in the mid-19th century\u2014widening streets and connecting monuments across the existing fine-grained city\u2014demonstrates the accommodation of a new texture within an existing city, in response to its growth. The addition of a new scale of street and pubic space added to Paris\u2019 hierarchy of streets. As argued by Serge Salat, this augmented \u201cits capacity for adaptation, and its versatility\u201d through grafting a new scale of the city to the older smaller ones \u201cwithout eliminating them\u201d (<span class=\"Laws-highlight---italics--red\"><a href=\"#Law34\">Law 34<\/a>&#8211;<a href=\"#Law35\">35<\/a><\/span>) (Salat, 2011, p. 79).<\/p>\n<p class=\"References\">FURTHER READING (full citations found in <a href=\"https:\/\/pressbooks.bccampus.ca\/settlement\/back-matter\/bibliography\/\">reference list<\/a>):<\/p>\n<ul>\n<li><strong>Constantino Doxiadis<\/strong> &#8211; <em><span class=\"Body---Book-titles---italics\">Ekistics: An Introduction to the Science of Human Settlements<\/span><\/em><\/li>\n<li class=\"References---Bullets\"><strong>Anthony E.J.
