  48. SETTLEMENT IN THE PHILIPPINES
  49. Pre-colonial Times SETTLEMENT IN THE PHILIPPINES - Like other cities in the world the earliest Filipino communities developed out of the need for their inhabitants to band together. - They were formed for security, or to be close to critical resources like food and water. Most of the earliest towns were by the coast for the fisherfolk or were where there was abundant agricultural land for the farmers. - The community unit was the barangay, consisting of 30 to 100 families.
  50. The Spanish Colonial Times Settlement Planning in the Phils. Laws of the Indies - In 1573, King Philip II proclaimed the Laws of the Indies that established uniform standards and planning procedures for colonial settlements. - These laws provided guidelines for site selection, layout and dimensioning of streets and squares, the location of civic and religious buildings, open space, cultivation and pasturing lands, and even the main procedural phases of planning and construction.
  51. Settlement Planning in the Phils. - The Plaza Complex- a result of several ordinances of the Laws of the Indies. - The plaza is surrounded by important buildings such as the: Catholic church Municipal or town hall Marketplace and merchant’s stores Elementary school The homes of the “principalia” Other government buildings
  52. Settlement Planning in the Phils. Intramuros - The walled city of Manila - 1.2 sq. KM in area; perimeter is 3.4 KM - home of the Spanish (except for the Friars & the high ranking officials) - decentralization occurred and settlements were built in Malate, San Miguel, and Paco, among other areas
  53. Settlement Planning in the Phils. The American Period The American Agenda - guide urban growth and physical development - put more emphasis on other values such as sanitation, housing, and aesthetic improvements. Daniel Burnham - Architect / planner who designed Chicago, San Francisco, and parts of Washington D.C.
  54. -Brought in to design Manila and the “summer capital” of Baguio Luneta
  55. Settlement Planning in the Phils. - Designed with grand avenues and a strong central civic core Burnham’s Design for Manila - Included a civic mall to house national buildings (only the Finance & Agriculture buildings were built) - Fronted Manila Bay like most Baroque plans fronted a large body of water
  56. Settlement Planning in the Phils. - On July 31, 1903, by virtue of Act No. 183, the city of Manila was incorporated Manila as the first chartered city - Manila encompassed Intramuros, and the towns of Binondo, Tondo, Sta. Cruz, Malate, Ermita, Paco, and Pandacan. - The population then was 190,000 people
  57. Settlement Planning in the Phils. - Quiapo- the illustrado territory; the enclave of the rich and powerful. Also the manifestation of folk religiosity. The Arrabales Growth of Manila - Binondo- the trading port developed by the Chinese and Arabs - Sta. Cruz- the main commercial district with swirls of shops, movie houses, restaurants, etc. - San Nicolas- also a commercial town built by the Spanish with streets of “specialized” categories (i.e. ceramics, soap, etc.) - Sampaloc- centered on two churches (Our Lady of Loreto and Saint Anthony of Padua). Also known as the first “University Town”.
  58. Settlement Planning in the Phils. Later Suburbs - San Miguel (Malacañang)- where rest-houses were built for the Spanish government - Malate- the early “summer resort” of wealthy and cultured Filipinos. Then became the first fishing and salt-making town - Ermita- early tourist belt (red-light district) - Paco- first town built around a train station - Pandacan- town built by the Americans for Oil depots
  59. Settlement Planning in the Phils. Further Suburbanization Quezon City as the new capitol city -In 1939, Commonwealth Act No. 457, authorized the transfer of the capitol to an area of 1572 hectares -A master plan of Quezon City was completed in 1941 by Architects Juan Arellano, Harry T. Frost, Louis Croft, and Eng. A.D. Williams - “City beautiful” plan reflected the aspirations of an emerging nation and the visions of a passionate leader
  60. Settlement Planning in the Phils. -In 1946, a search committee was formed to find a new site Constitution Hill -a 158 ha area in the Novaliches watershed was selected and called Constitution Hill and National Government Center -The three seats of government were to form a triangle at the center of the complex -It included a 20 hectare civic space referred to as the Plaza of the Republic
  61. Settlement Planning in the Phils. Philippine Homesite and Housing Corporation - Precursor of the National Housing Authority Philamlife Homes - icon of middle class suburbanization - Built homes for the masses (“the projects”, i.e. proj.4, proj. 6, etc.) - Master Plan designed by Architect and Planner, Carlos P. Arguelles, based on suburban developments in California with modifications BLISS (bagong lipunan sites and services) - Walk-up developments for government sector
  62. Settlement Planning in the Phils. Metro Manila Central Business Districts - Manila CBD- this traditional CBD is a center of business and commerce, has a population nucleus, and seats the national government - Makati CBD- a business, financial, commercial, convention, and recreational center of the Metropolitan Region covering an area of 979 hectares. Begun by the Ayala conglomerate in 1948. - Ortigas CBD- another business, financial, convention, shopping, and recreational node. Developed by the Ortigas conglomerate in the 1950s, it’s present configuration fully developed only in the late 80s. The area covers 600 hectares.
  63. Settlement Planning in the Phils. - Cubao CBD- developed in the 1960s by the Araneta Family, Cubao was intended as an alternative business center in the Eastern side of the metropolis. This 37 hectare property now reflects more of a bazaar economy, though plans are now being developed to convert the area to a more modern commercial and recreational center. - Emerging CBDs Fort Bonifacio Global City- 500 ha of prime land Boulevard 2000- 1167 ha of reclaimed land to revive Manila as a city of commerce and tourism Filinvest Corporate City- joint venture of government and private sector. Accessible to industrial estates and technological parks
  64. KEVIN LYNCH
  65. Kevin Lynch’s Images of the City Physical elements that create the image of the city
  66. Paths Kevin Lynch’s Images of the City - Channels along which the observer moves - Predominant element for many person’s image - Other elements are arranged and related through paths - Strong paths are: easily identifiable have continuity and directional quality are aligned with a larger system - Spatial extremes highlight paths
  67. Kevin Lynch’s Images of the City Edges - Linear elements not used or considered as paths - Lateral references, not coordinate axes - May be barriers or seams - Not as dominant as paths but are important organizing features visually prominent continuous and impenetrable to cross movement - Strong edges are: - Edges can be disruptive to city form
  68. Kevin Lynch’s Images of the City Districts - Medium to large sections of a city, conceived of as two-dimensional - Observer can mentally enter “inside of” - Recognizable as having some common, identifying character - Dominance depends upon the individual and the given district
  69. Kevin Lynch’s Images of the City activity and use building types and detail inhabitants (ethnic or class) - Physical characteristics have a variety of components physical characteristics (topography, boundaries, age, etc.)
  70. Kevin Lynch’s Images of the City Nodes - May be thematic concentrations - Points, strategic spots by which an observer can enter - Intensive foci from which observer is traveling - Junctions and Concentrations - Directly related to the concept of paths and the concept of districts
  71. Kevin Lynch’s Images of the City Landmarks - Point references considered to be external to the observer - Physical elements that may vary widely in scale - Unique and special in place of the continuities used earlier - Sequential series of landmarks as traveling guides
  72. IAN BENTLEY
  73. Permeability Ian Bentley’s Responsive Env’ts - Places must be accessible to people to offer them choice - Public and private access must be complementary - Physical and visual permeability depends on how the network of public space divides the environment into blocks - There is a decline in public permeability because of current design trends Scale of development Hierarchical layout Segregation
  74. Variety Ian Bentley’s Responsive Env’ts - Variety offers users a choice of experiences - Variety of experience implies places with varied forms, uses, and meanings - Developers and planners are more concerned with economic performance and easier management, than with variety - Variety of uses depends on three main factors: range of activities possibility of supply extent to which design encourages positive interactions - Variety also depends on feasibility: economic, political, and functional
  75. Legibility Ian Bentley’s Responsive Env’ts - Degree of choice depends on how legible it is: how layout is understood - Legibility is important at two levels: physical form and activity patterns - Legibility in the old days: important buildings stood out - Legibility of form and use is reduced in the modern environment - Separating pedestrians from vehicles also reduces legibility - Legibility is strengthened by Lynch’s physical elements of the city
  76. Robustness Ian Bentley’s Responsive Env’ts - Environments which can be used for many different purposes - There must be a distinction between large scale and small scale robustness - There are three key factors that support long term robustness: Building depth Access Building height - The design of small scale robustness depends on extra factors hard and soft spaces active and passive spaces
  77. Visual Appropriateness Ian Bentley’s Responsive Env’ts - Visual Appropriateness focuses on details - A vocabulary of visual cues must be found to communicate levels of choice - Interpretations can reinforce responsiveness by : supporting the place’s legibility supporting the place’s variety supporting the place’s robustness
  78. Richness Ian Bentley’s Responsive Env’ts - The variety of sense experiences that users can enjoy - There are two ways for users to choose from different sense experiences focusing their attention on different sources of sense experience moving away from one source to another - The basis of visual richness depends on the presence of visual contrasts
  79. Ian Bentley’s Responsive Env’ts - The sense of motion: gained through movement - The sense of smell: can not be directed - The sense of hearing: user has limited control - The sense of touch: voluntary and involuntary - The sense of sight: most dominant in terms of information input and is the one easiest to control
  80. Personalization Ian Bentley’s Responsive Env’ts - allows people to achieve an environment that bears the stamp of their own tastes and values - makes a person’s pattern of activities more clear - Users personalize in two ways: to improve practical facilities and to change the image of a place
  81. Ian Bentley’s Responsive Env’ts - Personalization comes in two levels: Private Public - Personalization is affected by three key factors: Tenure building type technology - Users personalize as an affirmation of their own tastes and values and because they perceive existing image as inappropriate
  82. Ian Bentley’s Responsive Env’ts permeability: designing the overall layout of routes and development blocks variety: locating uses on the site legibility: designing the massing of the buildings and the enclosure of public space robustness: designing the spatial and constructional arrangement of individual buildings and outdoor spaces visual appropriateness: designing the external image richness: developing the design for sensory choice personalization: making the design encourage people to put their own mark on the places where they live and work Putting it all together…
  83. URBAN FORM AND FUNCTION
  84. Urban Form and Function LandformTopography Relationship with Nature cities within nature cities and nature nature within cities
  85. Urban Form and Function Shaperadiocentric- a large circle with radial corridors of intense development emanating from the center rectilinear- usually with two corridors of intense development crossing the center; usually found in small cities rather than in large star- radiocentric form with open spaces between the outreaching corridors of development
  86. Urban Form and Function ring- a city built around a large open space linear- usually the result of natural topography which restricts growth; may also be a transportation spine branch- a linear span with connecting arms
  87. Urban Form and Function sheet- a vast urban area with little or no articulation articulated sheet- a sheet accented by one or more central clusters and several subclusters
  88. Urban Form and Function satellite- constellation of cities around a main center constellation- a series of nearly equal sized cities in close proximity
  89. Size & Density Urban Form and Function - physical extent – measured in KMs across, or center to outskirts, or square KM - density formulas- number of inhabitants with respect to physical size; can be computed in several ways: number of people per sq. KM or hectare number of families per block (residential density) number of houses per sq. KM or hectare amount of building floor area per section automobile population, Floor Area Ratio (FAR), etc.
  90. Urban Form and Function Routes - outlying routes - approach routes
  91. Urban Form and Function Urban Spaces -Urban spaces- well-defined public streets; plazas, parks, playgrounds, quadrangles, etc.
  92. Urban Form and Function Architecture - scale - character/ theme - grain/ texture
  93. Urban Form and Function Details- traffic signs, billboards, store signs, etc. - sidewalks, street furniture, urban landscaping, pavers, etc. - street vendors, traffic enforcers, entertainers, etc. - ethnic background, social class, sex, etc. - activities
  94. Urban Form and Function Movement- pedestrian - vehicular - channelization
  95. Urban Form and Function City Functions Economic Defense and Protection -A basic and continuing function. The city acts as producers and marketplaces -Locating cities at strategic points is important for the exchange of goods -Historic urban functions of the city, though quite obsolete at present -Cities were once built to withstand sieges from migrating tribes, or frequent raids from enemies
  96. Urban Form and Function Worship and Government Transportation -The prime function of the city throughout history -Cities were built around temples, shrines, and pyramids in ancient Egypt, Greece, and Rome -Greatly influences the location of cities since they are dependent on geography -New means of transportation have enabled people to live in much larger more spread out cities -The medieval cathedral was the center of the city, as were renaissance palaces and castles
  97. Urban Form and Function Education and Culture Housing -Cities have always been the seat of academy and scholarship and is a continuing function -Due to the diversity of people, ideas, jobs, etc., the city is seen as an educator. -The largest and simplest function of a city -Through the years, housing functions of the inner city have shifted to outlying areas -Ancient theaters, religious festivals, city beautification, etc. is a reflection of cultural pride.
  98. URBAN MODELS
  99. Urban Models Concentric Zone Theory - the geographer E.W. Burgess - includes transition zone for eventual CBD expansion - has some deficiencies but simplicity has stood the test of time
  100. Urban Models Sector Model- the economist Homer Hoyt - developed under the premise that other uses grow with the CBD - consistent with the observation that most cities grow in the direction of the higher income
  101. Urban Models Multiple Nuclei Model - by Chauncy Harris & Edward Pullman (geographers) - uses do not evolve around a single core but at several nodes and focal points - recognizes that different activities have varying accessibility requirements
  102. Urban Models Urban Realms - by James Vance - presents the emergence of self-sufficient sectors - independent urban realms brought by the impact of the automobile
  103. URBAN DESIGN CONTROLS
  104. Urban Design Controls Floor Area Ratio -the proportions between the built area and the lot area also referred to as ‘Plot Ratio’ Floor Space Index (FSI) -established by dividing the area of the total floor-space of the buildings on any by the site area, including half the area of any roads adjoining it
  105. Urban Design Controls Land Use Planning and Zoning - Defined as the legal regulation of the use of land - An application of the police power for the protection of the public health, welfare, and safety Incentive Zoning - allowing builders and developers more space if they provide certain desirable features and amenities such as plazas, arcades, and other open spaces Cluster Zoning - Creating special zoning policies and regulations for medium to large sized controlled developments - Allocating types of uses based on growth patterns
  106. Urban Design Controls Urban Design Guidelines - building heights - setbacks - building bulk - Architectural character
  107. Urban Design Controls Environmental Impact Statement - for large projects developers are required to outline possible effects of the project on the environment. The outline includes the following: Description of the project Description of existing environments (physical, social, economic, historical, and aesthetic) Impact on the environment (conditions evaluated) Adverse environmental effects Alternatives to proposed action taken Long range impacts Irreversible and irretrievable communities of resources likely to result from implementation of proposed project
  108. Urban Design Controls Environmental Preservation Conservation, Restoration & Adaptive Reuse - Conservation- a term used interchangeably with preservation but having the rather more positive connotation of adaptation of parts of buildings while retaining the essential spirit of the original conservation area—an area containing a group of buildings of special architectural or historical significance, which a Local Authority may designate. - protecting the environment from urban growth by restricting development in certain areas, especially in sensitive areas such as wetlands, coastal areas, and mountain environments
  109. Urban Design Controls - Urban Renewal- a general term to describe the idea of consciously renewing the outworn areas of towns and cities; covers most aspects of renewal, including both redevelopment and rehabilitation “The process of cleaning slum areas which are economically & physically beyond repair, rehabilitation areas where houses & neighborhood facilities can be restored to come up to health, safety, & good living standards, & protective measures in order to prevent enrichment of undesirable influences” – (exam question)
  110. Urban Design Controls - Adaptive Reuse- converting old, usually historic buildings, sections of, or entire districts to new uses other than their original purpose. In many U.S. cities adaptive reuse is encouraged by special tax incentives - Rehabilitation- term used to describe the idea of repairing, redecorating and in some cases converting, existing structurally sound property to a standard compatible with modern requirements of amenity and health
  111. Urban Planning Terms -Invasion- a type of urban ecological process defined as the entrance of a new population and / or facilities in an already occupied area -Centralization- an urban ecological process in city land use patterning referring to an increase in population at a certain geographic center - Gentrification- improving the physical set-up and consequently affecting the market for previously run-down areas -Block-boosting- “forcing” the old population out of the area because of social or racial differences
  112. EMERGING THEORIES
  113. Emerging Theories Planned Unit Developments - sometimes referred to as cluster zoning - used in areas that are being intensively developed for the first time - ordinary zoning regulations can be suspended for this particular property - usually consists of a variety of uses, anchored by commercial establishments and supported by office and residential space
  114. Transit Oriented Developments • Most TODs place residents within 600 to 700m of transit stations. • This is equivalent to an average walking time of about 5 minutes. Transit Oriented Developments - a mixed use community with an average 670 meter distance of a transit stop and commercial core area. TODs mix residential, retail, office, open space, and public uses in a walkable environment, making it convenient for residents and employees to travel by transit, bicycle, foot, or car.
  115. Transit Oriented Developments • Allows residents to have easy access to transit stations, lessening dependence on the automobile. • Boosts transit ridership and revenue • With TOD, the city and the transit system “meet in the middle”
  116. Transit Oriented developments - Urban TOD- are located directly on the trunk line transit network: at light rail, heavy rail, or express bus stops. They should be developed with high commercial intensities, job clusters, and moderate to high residential densities
  117. Transit Oriented Developments - Neighborhood TOD- on a local or feeder bus line within 10 minutes transit travel time (no more than 3 miles) from a trunk line transit stop. They should place an emphasis on moderate density residential, service, retail, entertainment, civic, and recreational uses.
  118. Transit Oriented Developments • The local street system should be recognizable and interconnected, converging to transit stops, core commercial areas or open spaces • Streets must be pedestrian friendly • Street and Circulation System
  119. Emerging Theories Distribution of TODs- TODs should be located to maximize access to core commercial areas without relying solely on arterials. TODs with major competing retail centers should be spaced a minimum of 1 mile apart and should be distributed to serve different neighborhoods. When located on fixed rail transit systems, they should be located to allow efficient station spacing

  126. New Urbanism Hierarchy of Spaces The Region - urbanism, defined by its diversity, pedestrian scale, public space & structure of bounded neighborhoods, should be applied throughout a metropolitan region regardless of location. - The entire region should be designed according to similar urban principles. ( Region, City, Neighborhood, District, Block, Street )
  127. New Urbanism The neighborhood, the district, & the corridor - these three are the fundamental organizing elements of New Urbanism neighborhoods are urbanized areas with a balanced mix of human activity districts are areas dominated by a single activity corridors are connectors and separators of neighborhoods and districts

Their proper configuration and placement relative to each other determines the character of each settlement
  129. New Urbanism The Context of New Urbanism - The neighborhood has a discernible center or a focal point - Most of the dwellings are within a five-minute walk of the center, an average of roughly 600 to 700 meters (2,000 feet)
  130. New Urbanism - There is a variety of dwelling types - There are mixed uses - Streets within the neighborhood are a connected network, preferably a grid pattern, which disperses traffic by providing a variety of pedestrian and vehicular routes to any destination
  131. New Urbanism - There are small playgrounds near every dwelling – not more than 200 meters away.

New Urbanism -An elementary school is close enough so that most children can walk from their home. - The streets and sidewalks are covered with rows of trees and other landscaping elements that provide shade to pedestrians and an overall pleasant environment - Parallel parking will also be allowed along the streets, with trees in between each designated space
  133. New Urbanism - Sidewalks are wide, at least 3.0 meters, and will be free from dangerous obstructions except for landscaping elements and street furniture that will invite pedestrians to sit. - Storefronts are also built close to the sidewalk, with wide window openings and visible entrances that are inviting to the pedestrian
  134. New Urbanism -Buildings in the neighborhood center are placed close to the street, creating a well-defined “outdoor room”. - Prominent sites at the termination of street vistas or in the neighborhood center are reserved for civic buildings.
  135. New Urbanism - Parking lots and garage doors rarely front the street. Parking is relegated to underground, to multi-level structures, or to the rear of buildings, usually accessed by alleys.
  136. New Urbanism - In areas with bodies of water of significant size, buildings will be built facing the water, rather than having the water in its backyard
