152-505: West Lakes is western suburb of Adelaide , South Australia , within the City of Charles Sturt . Developed in the 1970s as a public - private joint venture , it's noted for its manmade tidal lake and Delfin Island, a residential island set within the lake. It was renamed John Dyer Lake in honor of the former Mayor, John Raymond Dyer OAM, recognizing his significant influence and dedication to

304-481: A masterplanned , mixed-use subdivision on the former Football Park precinct named "WEST". The area bounded by Frederick Road, West Lakes Boulevard, Brebner Drive and Football Park/AAMI Stadium — formerly home to the Crows Shed, a large grass oval, and a grandstand — forms the development site. Housing typology largely consists of townhouses and apartments , deviating from the detached, single-family character of

456-602: A 51,240-seat sports stadium where AFL and SANFL games were played. Demolition of the grandstands and light towers were completed in 2019. The oval itself was left intact, and currently serves as the home training ground for the Adelaide Football Club (similar to Waverley Park in Melbourne ). A Douglas C-47 Skytrain military transport aircraft was owned by the McDonald's adjacent Westfield West Lakes, used as part of

608-514: A belief summed up in a housing poster of the period "you cannot expect to get an A1 population out of C3 homes" – referring to military fitness classifications of the period. The committee's report of 1917 was taken up by the government, which passed the Housing, Town Planning, &c. Act 1919 , also known as the Addison Act after Christopher Addison , the then Minister for Housing. The Act allowed for

760-573: A city or town or to a separate municipality or unincorporated area outside a town or city. Although a majority of Americans regard themselves as residents of suburban communities, the federal government of the United States has no formal definition for what constitutes a suburb in the United States, leaving its precise meaning disputed. In Canada, the term may also be used in the British sense, especially as cities annex formerly outlying areas. In

912-546: A city's expansion, such as Ealing , Bromley , and Guiseley . In Ireland, this can be seen in the Dublin suburban areas of Swords, Blanchardstown , and Tallaght . The history of suburbia is part of the study of urban history , which focuses on the origins, growth, diverse typologies, culture, and politics of suburbs, as well as on the gendered and family-oriented nature of suburban space. Many people have assumed that early-20th-century suburbs were enclaves for middle-class whites,

1064-404: A component of these newly designed suburbs which were booming in population. The television helped contribute to the rise of shopping centers by allowing for additional advertisement through the medium in addition to creating a desire among consumers to buy products that are shown being used in suburban life on various television programs. Another factor that led to the rise of these shopping centers

1216-475: A concept that carries tremendous cultural influence yet is actually stereotypical. Some suburbs are based on a society of working-class and minority residents, many of whom want to own their own house. Meanwhile, other suburbs instituted "explicitly racist" policies to deter people deemed as "other", a practice most common in the United States in contrast to other countries around the world. Mary Corbin Sies argues that it

1368-623: A dry bulk density (density of soil taking into account voids when dry) between 1.1 and 1.6 g/cm , though the soil particle density is much higher, in the range of 2.6 to 2.7 g/cm . Little of the soil of planet Earth is older than the Pleistocene and none is older than the Cenozoic , although fossilized soils are preserved from as far back as the Archean . Collectively the Earth's body of soil

1520-559: A further distance from them. In Japan, the construction of suburbs has boomed since the end of World War II and many cities are experiencing the urban sprawl effect. In Mexico, suburbs are generally similar to their United States counterparts. Houses are made in many different architectural styles which may be of European, American and International architecture and which vary in size. Suburbs can be found in Guadalajara , Mexico City, Monterrey , and most major cities. Lomas de Chapultepec

1672-1006: A high of nearly two-thirds of Calgary CMA residents (67%), to a low of about one-third of Montréal CMA residents (34%). Large cities in Canada acquired streetcar suburbs in the late 19th and early 20th centuries. Modern Canadian suburbs tend to be less automobile-centric than those in the United States, and public transit use is encouraged but can be notably unused. Throughout Canada, there are comprehensive plans in place to curb sprawl. Population and income growth in Canadian suburbs had tended to outpace growth in core urban or rural areas, but in many areas, this trend has now reversed. The suburban population increased by 87% between 1981 and 2001, well ahead of urban growth. The majority of recent population growth in Canada's three largest metropolitan areas ( Greater Toronto , Greater Montréal, and Greater Vancouver ) has occurred in non-core municipalities. This trend

1824-471: A large stand–alone house. In the suburbs, where stand–alone houses are the rule, lots may be 85 feet (26 m) wide by 115 feet (35 m) deep, as in the Chicago suburb of Naperville . Manufacturing and commercial buildings were segregated in other areas of the city. Alongside suburbanization, many companies began locating their offices and other facilities in the outer areas of the cities, which resulted in

1976-417: A larger metropolitan area such as a county, district or borough . In the United States, regions beyond the suburbs are known as "exurban areas" or exurbs ; exurbs have less population density than suburbs, but still more than rural areas. Suburbs and exurbs are sometimes linked to the nearby city economically, particularly by commuters. Suburbs first emerged on a large scale in the 19th and 20th centuries, as

2128-451: A medium for plant growth , making it a critically important provider of ecosystem services . Since soil has a tremendous range of available niches and habitats , it contains a prominent part of the Earth's genetic diversity . A gram of soil can contain billions of organisms, belonging to thousands of species, mostly microbial and largely still unexplored. Soil has a mean prokaryotic density of roughly 10 organisms per gram, whereas

2280-550: A meeting point for those who lived within suburban America at this time. These centers thrived offering goods and services to the growing populations in suburban America. In 1957, 940 shopping centers were built and this number more than doubled by 1960 to keep up with the demand of these densely populated areas. Very little housing had been built during the Great Depression and World War II , except for emergency quarters near war industries. Overcrowded and inadequate apartments

2432-435: A modern home in beautiful countryside with a fast railway-service to central London. By 1915 people from across London had flocked to live the new suburban dream in large newly built areas across north-west London. Suburbanization in the interwar period was heavily influenced by the garden city movement of Ebenezer Howard and the creation of the first garden suburbs at the turn of the 20th century. The first garden suburb

2584-419: A net absorption of oxygen and methane and undergo a net release of carbon dioxide and nitrous oxide . Soils offer plants physical support, air, water, temperature moderation, nutrients, and protection from toxins. Soils provide readily available nutrients to plants and animals by converting dead organic matter into various nutrient forms. Components of a silt loam soil by percent volume A typical soil

2736-409: A new housing development on the 17-hectare former Port Adelaide Wastewater Treatment Plant, adjacent Frederick Road. The area bounded by Frederick Road, the northern boundary of Lochside Drive, the tidal lake, and existing homes on Mariners Crescent, forms the development site. Almost 500 new homes, in the form of townhouses and apartments, will form the development. One of the two heritage buildings on

2888-549: A pH of 9, plant growth is reduced. High pH results in low micro-nutrient mobility, but water-soluble chelates of those nutrients can correct the deficit. Sodium can be reduced by the addition of gypsum (calcium sulphate) as calcium adheres to clay more tightly than does sodium causing sodium to be pushed into the soil water solution where it can be washed out by an abundance of water. There are acid-forming cations (e.g. hydronium, aluminium, iron) and there are base-forming cations (e.g. calcium, magnesium, sodium). The fraction of

3040-507: A phenomenon known as white flight . After World War II, the availability of FHA loans stimulated a housing boom in American suburbs. In the older cities of the northeast U.S., streetcar suburbs originally developed along train or trolley lines that could shuttle workers into and out of city centers where the jobs were located. This practice gave rise to the term " bedroom community ", meaning that most daytime business activity took place in

3192-402: A play area for children's parties. The plane was removed in the late 1990s, and is now being restored privately. Suburb A suburb (more broadly suburban area ) is an area within a metropolitan area which is predominantly residential and within commuting distance of a large city. Suburbs can have their own political or legal jurisdictions, especially in the United States, but this

3344-435: A problem of public order (keeping the unwelcome poorest classes together with the criminals, in this way better controlled, comfortably remote from the elegant "official" town). On the other hand, the expected huge expansion of the town soon effectively covered the distance from the central town, and now those suburbs are completely engulfed by the main territory of the town. Other newer suburbs (called exurbs ) were created at

3496-731: A result of a trade-off between toxicity and requirement most nutrients are better available to plants at moderate pH, although most minerals are more soluble in acid soils. Soil organisms are hindered by high acidity, and most agricultural crops do best with mineral soils of pH 6.5 and organic soils of pH 5.5. Given that at low pH toxic metals (e.g. cadmium, zinc, lead) are positively charged as cations and organic pollutants are in non-ionic form, thus both made more available to organisms, it has been suggested that plants, animals and microbes commonly living in acid soils are pre-adapted to every kind of pollution, whether of natural or human origin. In high rainfall areas, soils tend to acidify as

3648-539: A result of improved rail and road transport, which led to an increase in commuting. In general, they are less densely populated than inner city neighborhoods within the same metropolitan area, and most residents routinely commute to city centers or business districts via private vehicles or public transits ; however, there are many exceptions, including industrial suburbs , planned communities , and satellite cities . Suburbs tend to proliferate around cities that have an abundance of adjacent flat land. The English word

3800-401: A result, layers (horizons) form in the soil profile. The alteration and movement of materials within a soil causes the formation of distinctive soil horizons . However, more recent definitions of soil embrace soils without any organic matter, such as those regoliths that formed on Mars and analogous conditions in planet Earth deserts. An example of the development of a soil would begin with

3952-473: A settled life moved in masses to the suburbs. Levittown developed as a major prototype of mass-produced housing. Due to the influx of people in these suburban areas, the amount of shopping centers began to increase as suburban America took shape. These malls helped supply goods and services to the growing urban population. Shopping for different goods and services in one central location without having to travel to multiple locations, helped to keep shopping centers

4104-412: A soil can be said to be developed, and can be described further in terms of color, porosity, consistency, reaction ( acidity ), etc. Water is a critical agent in soil development due to its involvement in the dissolution, precipitation, erosion, transport, and deposition of the materials of which a soil is composed. The mixture of water and dissolved or suspended materials that occupy the soil pore space

4256-399: A soil determines its ability to supply available plant nutrients and affects its physical properties and the health of its living population. In addition, a soil's chemistry also determines its corrosivity , stability, and ability to absorb pollutants and to filter water. It is the surface chemistry of mineral and organic colloids that determines soil's chemical properties. A colloid

4408-737: A solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three- state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate , relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion . Given its complexity and strong internal connectedness , soil ecologists regard soil as an ecosystem . Most soils have

4560-447: A total duration of 31 years. In 2000, the City of Charles Sturt undertook soil testing in the area of West Lakes surrounding the former Port Adelaide Wastewater Treatment Plant adjacent Frederick Road. Test results indicated cadmium present in the soil, affecting 200 homes. This was largely due to the dispersal of sludge over the land during initial development earthworks in the 1970s. In

4712-573: A total price of $ 10,000. Veterans could get one with a much lower down payment. At the same time, African Americans were rapidly moving north and west for better jobs and educational opportunities than were available to them in the segregated South. Their arrival in Northern and Western cities en masse, in addition to being followed by race riots in several large cities such as Philadelphia , Los Angeles , Detroit , Chicago , and Washington, D.C. , further stimulated white suburban migration. The growth of

4864-472: A valence of two, converts to (40 ÷ 2) × 1 milliequivalent = 20 milliequivalents of hydrogen ion per 100 grams of dry soil or 20 meq/100 g. The modern measure of CEC is expressed as centimoles of positive charge per kilogram (cmol/kg) of oven-dry soil. Most of the soil's CEC occurs on clay and humus colloids, and the lack of those in hot, humid, wet climates (such as tropical rainforests ), due to leaching and decomposition, respectively, explains

5016-553: Is 0.04%, but in the soil pore space it may range from 10 to 100 times that level, thus potentially contributing to the inhibition of root respiration. Calcareous soils regulate CO 2 concentration by carbonate buffering , contrary to acid soils in which all CO 2 respired accumulates in the soil pore system. At extreme levels, CO 2 is toxic. This suggests a possible negative feedback control of soil CO 2 concentration through its inhibitory effects on root and microbial respiration (also called soil respiration ). In addition,

5168-601: Is a distinct European style originating from European influence during the mid-1600s when the Dutch settled the Cape. Houses like these are called Cape Dutch Houses and can be found in the affluent suburbs of Constantia and Bishopscourt . Large cities like Sydney and Melbourne had streetcar suburbs in the tram era. With the automobile, the Australian usage came about as outer areas were quickly surrounded in fast-growing cities, but retained

5320-603: Is a measure of the acidity or alkalinity of the soil. More precisely, it is a measure of hydronium concentration in an aqueous solution and ranges in values from 0 to 14 (acidic to basic) but practically speaking for soils, pH ranges from 3.5 to 9.5, as pH values beyond those extremes are toxic to life forms. At 25 °C an aqueous solution that has a pH of 3.5 has 10 moles H 3 O (hydronium ions) per litre of solution (and also 10 moles per litre OH ). A pH of 7, defined as neutral, has 10 moles of hydronium ions per litre of solution and also 10 moles of OH per litre; since

5472-509: Is a small, insoluble particle ranging in size from 1 nanometer to 1 micrometer , thus small enough to remain suspended by Brownian motion in a fluid medium without settling. Most soils contain organic colloidal particles called humus as well as the inorganic colloidal particles of clays . The very high specific surface area of colloids and their net electrical charges give soil its ability to hold and release ions . Negatively charged sites on colloids attract and release cations in what

5624-411: Is about 50% solids (45% mineral and 5% organic matter), and 50% voids (or pores) of which half is occupied by water and half by gas. The percent soil mineral and organic content can be treated as a constant (in the short term), while the percent soil water and gas content is considered highly variable whereby a rise in one is simultaneously balanced by a reduction in the other. The pore space allows for

5776-424: Is also a net sink of methane (CH 4 ) but a net producer of methane (a strong heat-absorbing greenhouse gas ) when soils are depleted of oxygen and subject to elevated temperatures. Soil atmosphere is also the seat of emissions of volatiles other than carbon and nitrogen oxides from various soil organisms, e.g. roots, bacteria, fungi, animals. These volatiles are used as chemical cues, making soil atmosphere

5928-545: Is also beginning to take effect in Vancouver , and to a lesser extent, Montréal . In certain cities, particularly Edmonton and Calgary , suburban growth takes place within the city boundaries as opposed to in bedroom communities. This is due to annexation and a large geographic footprint within the city borders. Calgary is unusual among Canadian cities because it has developed as a unicity – it has annexed most of its surrounding towns and large amounts of undeveloped land around

6080-925: Is an example of an affluent suburb, although it is located inside the city and by no means is today a suburb in the strict sense of the word. In other countries, the situation is similar to that of Mexico, with many suburbs being built, most notably in Peru and Chile, which have experienced a boom in the construction of suburbs since the late 1970s and early 1980s. As the growth of middle-class and upper-class suburbs increased, low-class squatter areas have increased, most notably "lost cities" in Mexico, campamentos in Chile, barriadas in Peru, villa miserias in Argentina, asentamientos in Guatemala and favelas of Brazil. Soil Soil consists of

6232-556: Is an important characteristic of soil. This ventilation can be accomplished via networks of interconnected soil pores , which also absorb and hold rainwater making it readily available for uptake by plants. Since plants require a nearly continuous supply of water, but most regions receive sporadic rainfall, the water-holding capacity of soils is vital for plant survival. Soils can effectively remove impurities, kill disease agents, and degrade contaminants , this latter property being called natural attenuation . Typically, soils maintain

6384-441: Is an urbanized nation where over 80% of the population lives in urban areas (loosely defined), and roughly two-thirds live in one of Canada's 33 census metropolitan areas (CMAs) with a population of over 100,000. However, of this metropolitan population, in 2001 nearly half lived in low-density neighborhoods, with only one in five living in a typical "urban" neighborhood. The percentage living in low-density neighborhoods varied from

6536-464: Is assumed acid-forming cations). Base saturation is almost in direct proportion to pH (it increases with increasing pH). It is of use in calculating the amount of lime needed to neutralise an acid soil (lime requirement). The amount of lime needed to neutralize a soil must take account of the amount of acid forming ions on the colloids (exchangeable acidity), not just those in the soil water solution (free acidity). The addition of enough lime to neutralize

6688-414: Is called the pedosphere . The pedosphere interfaces with the lithosphere , the hydrosphere , the atmosphere , and the biosphere . Soil has four important functions : All of these functions, in their turn, modify the soil and its properties. Soil science has two basic branches of study: edaphology and pedology . Edaphology studies the influence of soils on living things. Pedology focuses on

6840-401: Is called the soil solution. Since soil water is never pure water, but contains hundreds of dissolved organic and mineral substances, it may be more accurately called the soil solution. Water is central to the dissolution , precipitation and leaching of minerals from the soil profile . Finally, water affects the type of vegetation that grows in a soil, which in turn affects the development of

6992-421: Is dependent on the type of parent material , the processes that modify those parent materials, and the soil-forming factors that influence those processes. The biological influences on soil properties are strongest near the surface, though the geochemical influences on soil properties increase with depth. Mature soil profiles typically include three basic master horizons: A, B, and C. The solum normally includes

7144-801: Is derived from the Old French subburbe , which is in turn derived from the Latin suburbium , formed from sub (meaning "under" or "below") and urbs ("city"). The first recorded use of the term in English according to the Oxford English Dictionary appears in Middle English c. 1350 in the manuscript of the Midlands Prose Psalter, in which the form suburbes is used. In Australia, New Zealand, and South Africa, suburban areas (in

7296-401: Is induced. Capillary action is responsible for moving groundwater from wet regions of the soil to dry areas. Subirrigation designs (e.g., wicking beds , sub-irrigated planters ) rely on capillarity to supply water to plant roots. Capillary action can result in an evaporative concentration of salts, causing land degradation through salination . Soil moisture measurement —measuring

7448-531: Is likely home to 59 ± 15% of the species on Earth. Enchytraeidae (worms) have the greatest percentage of species in soil (98.6%), followed by fungi (90%), plants (85.5%), and termites ( Isoptera ) (84.2%). Many other groups of animals have substantial fractions of species living in soil, e.g. about 30% of insects , and close to 50% of arachnids . While most vertebrates live above ground (ignoring aquatic species), many species are fossorial , that is, they live in soil, such as most blind snakes . The chemistry of

7600-549: Is linked to the mainland by a singular road — West Lakes Boulevard – in addition to two pedestrian bridges. One on the west of the island links Bartley Terrace with Keppel Grove, and one on the east links Lochside Drive to Kerr Grove and Corcoran Drive. The Island Point apartment complex, completed in 1990, is prominently situated at the southern end of the island, and was an early pioneer of high-rise suburban apartment living in South Australia. Freshwater Lake, commonly known as

7752-477: Is more advanced. Most plant nutrients, with the exception of nitrogen , originate from the minerals that make up the soil parent material. Some nitrogen originates from rain as dilute nitric acid and ammonia , but most of the nitrogen is available in soils as a result of nitrogen fixation by bacteria . Once in the soil-plant system, most nutrients are recycled through living organisms, plant and microbial residues (soil organic matter), mineral-bound forms, and

7904-407: Is necessary to examine how "suburb" is defined as well as the distinction made between cities and suburbs, geography, economic circumstances, and the interaction of numerous factors that move research beyond acceptance of stereotyping and its influence on scholarly assumptions. The earliest appearance of suburbs coincided with the spread of the first urban settlements. Large walled towns tended to be

8056-593: Is not always the case, especially in the United Kingdom, where most suburbs are located within the administrative boundaries of cities. In most English-speaking countries , suburban areas are defined in contrast to central city or inner city areas, but in Australian English and South African English , suburb has become largely synonymous with what is called a " neighborhood " in the U.S. Due in part to historical trends such as white flight , some suburbs in

8208-409: Is referred to as cation exchange . Cation-exchange capacity is the amount of exchangeable cations per unit weight of dry soil and is expressed in terms of milliequivalents of positively charged ions per 100 grams of soil (or centimoles of positive charge per kilogram of soil; cmol c /kg ). Similarly, positively charged sites on colloids can attract and release anions in the soil, giving

8360-399: Is the primary linking thoroughfare through the development, extending from Port Road in the east through to Military Road in the west. The thoroughfare was initially planned to cut north-east through the established adjoining suburb Albert Park , however, protests from residents and the local parish resulted in an altered route that utilised (and renamed) part of Clark Terrace parallel to

8512-540: Is very little organic material. Basaltic minerals commonly weather relatively quickly, according to the Goldich dissolution series . The plants are supported by the porous rock as it is filled with nutrient-bearing water that carries minerals dissolved from the rocks. Crevasses and pockets, local topography of the rocks, would hold fine materials and harbour plant roots. The developing plant roots are associated with mineral-weathering mycorrhizal fungi that assist in breaking up

8664-672: The AUKUS are slated to be built for the Royal Australian Navy . Delivery of the first submarine is expected in the early 2040s. In addition to Westfield West Lakes, the suburb is also home to the Lakes Resort Hotel (established in 1985) and the West Lakes Golf Club — one of several within the coastal western suburbs. West Lakes was home to Football Park (also known by its sponsored name AAMI Stadium), which functioned as

8816-572: The FNB ("Soccer City") Stadium and south of the city in areas like Eikenhof, where the "Eye of Africa" planned community exists. This master-planned community is nearly indistinguishable from the most amenity-rich resort-style American suburbs in Florida, Arizona, and California, complete with a golf course, resort pool, equestrian facility , 24-hour staffed gates, gym, and BMX track, as well as several tennis, basketball, and volleyball courts. In Cape Town, there

8968-598: The Gold Coast . Early concept drawings of West Lakes didn't explicitly include a residential island. After initial earthworks and construction formed the island, two additional peninsulas were created through further excavation at the northern and southern tips of the island, resulting in more waterfront allotments. McDonald Grove and Martin Court service the peninsulas at the north and south of Delfin Island, respectively. Delfin Island

9120-594: The Grange railway line . A spur of the Grange railway line was planned to run parallel to West Lakes Boulevard, likely terminating near the shopping centre (currently Westfield West Lakes). This, however, didn't proceed due to financial constraints, and the reserved land was converted into Magarey Grove — a linear tree grove containing 100 spotted gum trees , each dedicated to the first 100 Magarey Medallists . In 2015, property developer Commercial & General commenced work on

9272-648: The Hampstead Garden Suburb . The suburb attracted the talents of architects including Raymond Unwin and Sir Edwin Lutyens , and it ultimately grew to encompass over 800 acres. During World War I, the Tudor Walters Committee was commissioned to make recommendations for the post war reconstruction and housebuilding. In part, this was a response to the shocking lack of fitness amongst many recruits during World War One, attributed to poor living conditions;

9424-490: The aeration of the soil and the ability of water to infiltrate and to be held within the soil. Soil water content can be measured as volume or weight . Soil moisture levels, in order of decreasing water content, are saturation, field capacity , wilting point , air dry, and oven dry. Field capacity describes a drained wet soil at the point water content reaches equilibrium with gravity. Irrigating soil above field capacity risks percolation losses. Wilting point describes

9576-561: The humus form ), the copedon (in intermediary position, where most weathering of minerals takes place) and the lithopedon (in contact with the subsoil). The soil texture is determined by the relative proportions of the individual particles of sand , silt , and clay that make up the soil. The interaction of the individual mineral particles with organic matter, water, gases via biotic and abiotic processes causes those particles to flocculate (stick together) to form aggregates or peds . Where these aggregates can be identified,

9728-403: The inner cities of the U.S. Examples include the banlieues of France, or the concrete suburbs of Sweden, even if the suburbs of these countries also include middle-class and upper-class neighborhoods that often consist of single-family houses . Following the growth of the middle class due to African industrialization, the development of middle class suburbs has boomed since the beginning of

9880-425: The mineralogy of those particles can strongly modify those properties. The mineralogy of the finest soil particles, clay, is especially important. Large numbers of microbes , animals , plants and fungi are living in soil. However, biodiversity in soil is much harder to study as most of this life is invisible, hence estimates about soil biodiversity have been unsatisfactory. A recent study suggested that soil

10032-485: The 1850s and eventually became a component of the Australian Dream . Toward the end of the century, with the development of public transit systems such as the underground railways , trams and buses, it became possible for the majority of a city's population to reside outside the city and to commute into the center for work. By the mid-19th century, the first major suburban areas were springing up around London as

10184-603: The 1930s through 1945, there were 1,450,000 constructed annually from 1946 through 1955. The G.I. Bill guaranteed low-cost loans for veterans, with very low down payments, and low interest rates. With 16 million eligible veterans, the opportunity to buy a house was suddenly at hand. In 1947 alone, 540,000 veterans bought one; their average price was $ 7300. The construction industry kept prices low by standardization—for example, standardizing sizes for kitchen cabinets, refrigerators and stoves allowed for mass production of kitchen furnishings. Developers purchased empty land just outside

10336-434: The 1990s, particularly in cities such as Cairo , Nairobi , Johannesburg , and Lagos . In an illustrative case of South Africa, RDP housing has been built. In much of Soweto , many houses are American in appearance, but are smaller, and often consist of a kitchen and living room, two or three bedrooms, and a bathroom. However, there are more affluent neighborhoods, more comparable to American suburbs, particularly east of

10488-448: The A and B horizons. The living component of the soil is largely confined to the solum, and is generally more prominent in the A horizon. It has been suggested that the pedon , a column of soil extending vertically from the surface to the underlying parent material and large enough to show the characteristics of all its horizons, could be subdivided in the humipedon (the living part, where most soil organisms are dwelling, corresponding to

The island consists primarily of quieter cul-de-sacs within distinct "neighbourhoods", where real estate is generally valued higher than in most other areas of West Lakes. The majority of roadways on the island are named after countries in the Caribbean and Polynesia , as well as other exotic islands such as Corfu and Bali . West Lakes Boulevard

10792-575: The Grand Central Terminal commuter hub that enabled its development. Westchester's true importance in the history of American suburbanization derives from the upper-middle class development of villages including Scarsdale , New Rochelle and Rye serving thousands of businessmen and executives from Manhattan. The suburban population in North America exploded during the post-World War II economic expansion . Returning veterans wishing to start

In 1992, the wider West Lakes project was awarded the inaugural Prix D’Excellence award by FIABCI, the International Real Estate Federation . Upon being announced the winner, West Lakes was described as: the project that produced the greatest synergy from all the real estate disciplines – quality of counselling, appraising, finance, marketing, management, maintenance and community benefits – without losing sight of

11096-476: The U.S., the development of the skyscraper and the sharp inflation of downtown real estate prices also led to downtowns being more fully dedicated to businesses, thus pushing residents outside the city center. While suburbs are often associated with the middle classes, in many parts of the developed world, suburbs can be economically distressed areas, inhabited by higher proportions of recent immigrants, with higher delinquency rates and social problems, reminiscent of

11248-440: The United Kingdom and Ireland, the term suburb simply refers to a residential area outside the city center, regardless of administrative boundaries. Suburbs, in this sense, can range from areas that seem more like residential areas of a city proper to areas separated by open countryside from the city center. In large cities such as London and Leeds, many suburbs are formerly separate towns and villages that have been absorbed during

11400-440: The United States have a higher population and higher incomes than their nearby inner cities. In some countries, including India, China, New Zealand, Canada, the United Kingdom, and parts of the United States, new suburbs are routinely annexed by adjacent cities due to urban sprawl . In others, such as Morocco , France, and much of the United States, many suburbs remain separate municipalities or are governed locally as part of

11552-406: The acronym CROPT. The physical properties of soils, in order of decreasing importance for ecosystem services such as crop production , are texture , structure , bulk density , porosity , consistency, temperature , colour and resistivity . Soil texture is determined by the relative proportion of the three kinds of soil mineral particles, called soil separates: sand , silt , and clay . At

11704-446: The addition of any more hydronium ions or aluminum hydroxyl cations drives the pH even lower (more acidic) as the soil has been left with no buffering capacity. In areas of extreme rainfall and high temperatures, the clay and humus may be washed out, further reducing the buffering capacity of the soil. In low rainfall areas, unleached calcium pushes pH to 8.5 and with the addition of exchangeable sodium, soils may reach pH 10. Beyond

11856-435: The affected properties that measures taken to reduce and prevent cadmium exposure will also work to mitigate PFAS exposure. Sampling of water in the vicinity, including shallow groundwater and lake water, determined that PFAS had contaminated the groundwater. The EPA advised residents to strictly avoid the use of groundwater, and that lake water, tap water and rainwater remain safe. Testing also confirmed that fish caught from

12008-452: The apparent sterility of tropical soils. Live plant roots also have some CEC, linked to their specific surface area. Anion exchange capacity is the soil's ability to remove anions (such as nitrate , phosphate ) from the soil water solution and sequester those for later exchange as the plant roots release carbonate anions to the soil water solution. Those colloids which have low CEC tend to have some AEC. Amorphous and sesquioxide clays have

12160-781: The appellation suburb ; the term was eventually applied to neighborhoods in the original core as well. In Australia, Sydney's urban sprawl has occurred predominantly in the Western Suburbs . The locality of Olympic Park was designated an official suburb in 2009. Bangladesh has multiple suburbs, Uttara & Ashulia to name a few. However, most suburbs in Dhaka are different from the ones in Europe & Americas . Most suburbs in Bangladesh are filled with high-rise buildings, paddy fields, and farms, and are designed more like rural villages. Canada

12312-437: The atmosphere due to increased biological activity at higher temperatures, a positive feedback (amplification). This prediction has, however, been questioned on consideration of more recent knowledge on soil carbon turnover. Soil acts as an engineering medium, a habitat for soil organisms , a recycling system for nutrients and organic wastes , a regulator of water quality , a modifier of atmospheric composition , and

12464-426: The basic cations are forced off the soil colloids by the mass action of hydronium ions from usual or unusual rain acidity against those attached to the colloids. High rainfall rates can then wash the nutrients out, leaving the soil inhabited only by those organisms which are particularly efficient to uptake nutrients in very acid conditions, like in tropical rainforests . Once the colloids are saturated with H 3 O ,

12616-494: The building of large new housing estates in the suburbs after the First World War , and marked the start of a long 20th century tradition of state-owned housing, which would later evolve into council estates . The Report also legislated on the required, minimum standards necessary for further suburban construction; this included regulation on the maximum housing density and their arrangement, and it even made recommendations on

12768-487: The city (then the largest in the world) became more overcrowded and unsanitary. A major catalyst for suburban growth was the opening of the Metropolitan Railway in the 1860s. The line later joined the capital's financial heart in the City to what were to become the suburbs of Middlesex . The line reached Harrow in 1880. Unlike other railway companies, which were required to dispose of surplus land, London's Met

12920-466: The city, installed tract houses based on a handful of designs, and provided streets and utilities, while local public officials raced to build schools. The most famous development was Levittown, in Long Island just east of New York City. It offered a new house for $ 1000 down and $ 70 a month; it featured three bedrooms, a fireplace, a gas range and gas furnace, and a landscaped lot of 75 by 100 feet, all for

13072-717: The city, with the working population leaving the city at night for the purpose of going home to sleep. Economic growth in the United States encouraged the suburbanization of American cities that required massive investments for the new infrastructure and homes. Consumer patterns were also shifting at this time, as purchasing power was becoming stronger and more accessible to a wider range of families. Suburban houses also brought about needs for products that were not needed in urban neighborhoods, such as lawnmowers and automobiles. During this time commercial shopping malls were being developed near suburbs to satisfy consumers' needs and their car–dependent lifestyle. Zoning laws also contributed to

13224-571: The city. As a result, most of the communities that Calgarians refer to as "suburbs" are actually inside the city limits. In the 2016 census, the City of Calgary had a population of 1,239,220, whereas the Calgary Metropolitan Area had a population of 1,392,609, indicating the vast majority of people in the Calgary CMA lived within the city limits. The perceived low population density of Calgary largely results from its many internal suburbs and

13376-565: The development. Today, West Lakes is home to the Westfield West Lakes shopping centre, Woodlake Shopping Centre on Frederick Road, the West Lakes Golf Club, and the Adelaide Football Club training grounds (formerly AAMI Stadium/ Football Park ). West Lakes has an irregular shape and shares borders with Port Adelaide , Queenstown , Royal Park , Seaton and Grange . Adjacent suburbs that also share lake frontage include Semaphore Park , Tennyson and West Lakes Shore . West Lakes

13528-436: The dry limit for growing plants. During growing season, soil moisture is unaffected by functional groups or specie richness. Available water capacity is the amount of water held in a soil profile available to plants. As water content drops, plants have to work against increasing forces of adhesion and sorptivity to withdraw water. Irrigation scheduling avoids moisture stress by replenishing depleted water before stress

13680-455: The era, was heavily influenced by the Art Deco movement, taking influence from Tudor Revival , chalet style , and even ship design. Within just a decade suburbs dramatically increased in size. Harrow Weald went from just 1,500 to over 10,000 while Pinner jumped from 3,000 to over 20,000. During the 1930s, over 4 million new suburban houses were built, the 'suburban revolution' had made England

13832-554: The first suburban districts sprung up around downtowns to accommodate those who wanted to escape the squalid conditions of the industrial towns. Initially, such growth came along rail lines in the form of ribbon developments , as suburban residents could commute via train to downtown for work. In Australia, where Melbourne would soon become the second-largest city in the British Empire, the distinctively Australasian suburb, with its loosely aggregated quarter-acre sections, developed in

13984-507: The focus around which smaller villages grew up in a symbiotic relationship with the market town . The word suburbani was first employed by the Roman statesman Cicero in reference to the large villas and estates built by the wealthy patricians of Rome on the city's outskirts. Towards the end of the Eastern Han Dynasty , until 190 AD, when Dong Zhuo razed the city, the capital Luoyang

14136-516: The following years, the state government recommended various measures to reduce and prevent exposure to cadmium, with funding allocated to implement these on a property-specific basis. In 2020, the South Australian Environment Protection Authority (EPA) was notified of the presence of per- and polyfluoroalkyl substances (PFAS) in groundwater , soils and sewage sludge in the same vicinity. The EPA notified owners of

14288-519: The formation, description (morphology), and classification of soils in their natural environment. In engineering terms, soil is included in the broader concept of regolith , which also includes other loose material that lies above the bedrock, as can be found on the Moon and other celestial objects . Soil is a major component of the Earth 's ecosystem . The world's ecosystems are impacted in far-reaching ways by

14440-419: The highest AEC, followed by the iron oxides. Levels of AEC are much lower than for CEC, because of the generally higher rate of positively (versus negatively) charged surfaces on soil colloids, to the exception of variable-charge soils. Phosphates tend to be held at anion exchange sites. Iron and aluminum hydroxide clays are able to exchange their hydroxide anions (OH ) for other anions. The order reflecting

14592-495: The ideal number of bedrooms and other rooms per house. Although the semi-detached house was first designed by the Shaws (a father and son architectural partnership) in the 19th century, it was during the suburban housing boom of the interwar period that the design first proliferated as a suburban icon, being preferred by middle-class home owners to the smaller terraced houses . The design of many of these houses, highly characteristic of

14744-417: The increased density of older suburbs and the growth of lower density suburbs even further from city centers. An alternative strategy is the deliberate design of "new towns" and the protection of green belts around cities. Some social reformers attempted to combine the best of both concepts in the garden city movement. In the U.S., 1950 was the first year that more people lived in suburbs than elsewhere. In

14896-632: The infiltration and movement of air and water, both of which are critical for life existing in soil. Compaction , a common problem with soils, reduces this space, preventing air and water from reaching plant roots and soil organisms. Given sufficient time, an undifferentiated soil will evolve a soil profile that consists of two or more layers, referred to as soil horizons. These differ in one or more properties such as in their texture , structure , density , porosity, consistency, temperature, color, and reactivity . The horizons differ greatly in thickness and generally lack sharp boundaries; their development

15048-623: The initial development, only single or double-storey homes could be built, with specific areas designated for taller and larger buildings (such as the shopping centre and apartments). In many instances, raft foundations were utilised in order to counteract subsidence and general movement due to the nature of the soil. Housing design during the initial development phase of West Lakes was controlled by land title encumbrances , with Delfin having guidelines in place to dictate acceptable architectural design and external finishes in accordance with their vision for individual neighbourhoods, as well as for

15200-406: The lake remain fit for human consumption, with PFAS levels low enough to not pose a threat. The most prominent feature of West Lakes, aside from Delfin Island, is the large freshwater lake. At the southern end of the lake, an underground inlet duct runs from Inlet Reserve out to shore at Tennyson Beach . At high tide, sea level rises above lake level and fresh seawater is fed into the lake through

15352-771: The large amount of undeveloped land within the city. The city actually has a policy of densifying its new developments. In China, the term suburb is new, although suburbs are already being constructed rapidly. Chinese suburbs mostly consist of rows upon rows of apartment blocks and condos that end abruptly into the countryside. Also new town developments are extremely common. Single family suburban homes tend to be similar to their Western equivalents; although primarily outside Beijing and Shanghai, also mimic Spanish and Italian architecture. In Hong Kong, however, suburbs are mostly government-planned new towns containing numerous public housing estates. However, other new towns also contain private housing estates and low density developments for

15504-551: The largely straight and wide southern portion of the lake was reserved for a 2 kilometre rowing course. Today, it's known as the A.M. Ramsay Regatta Course and is host to the annual Head of the River race. Officially opened on 17 March 1978 and named after the company that developed West Lakes, Delfin Island is a 106-hectare artificial residential island and remains unique in the context of South Australian urban developments — although man-made residential islands appear in places such as

15656-424: The location of residential areas outside of the city center by creating wide areas or "zones" where only residential buildings were permitted. These suburban residences are built on larger lots of land than in the central city. For example, the lot size for a residence in Chicago is usually 125 feet (38 m) deep, while the width can vary from 14 feet (4.3 m) wide for a row house to 45 feet (14 m) wide for

15808-713: The lower-density suburbs on the outskirts of the urban area. The term 'middle suburbs' is also used. Inner suburbs , such as Te Aro in Wellington, Eden Terrace in Auckland, Prahran in Melbourne and Ultimo in Sydney, are usually characterized by higher density apartment housing and greater integration between commercial and residential areas. In the United States and Canada , suburb can refer either to an outlying residential area of

15960-512: The most heavily suburbanized country in the world, by a considerable margin. Boston and New York City spawned the first major suburbs. The streetcar lines in Boston and the rail lines in Manhattan made daily commutes possible. No metropolitan area in the world was as well served by railroad commuter lines at the turn of the twentieth century as New York, and it was the rail lines to Westchester from

16112-429: The negatively charged colloids resist being washed downward by water and are out of reach of plant roots, thereby preserving the soil fertility in areas of moderate rainfall and low temperatures. There is a hierarchy in the process of cation exchange on colloids, as cations differ in the strength of adsorption by the colloid and hence their ability to replace one another ( ion exchange ). If present in equal amounts in

16264-412: The negatively-charged soil colloid exchange sites (CEC) that are occupied by base-forming cations is called base saturation . If a soil has a CEC of 20 meq and 5 meq are aluminium and hydronium cations (acid-forming), the remainder of positions on the colloids ( 20 − 5 = 15 meq ) are assumed occupied by base-forming cations, so that the base saturation is 15 ÷ 20 × 100% = 75% (the compliment 25%

16416-419: The next larger scale, soil structures called peds or more commonly soil aggregates are created from the soil separates when iron oxides , carbonates , clay, silica and humus , coat particles and cause them to adhere into larger, relatively stable secondary structures. Soil bulk density , when determined at standardized moisture conditions, is an estimate of soil compaction . Soil porosity consists of

16568-472: The ocean has no more than 10 prokaryotic organisms per milliliter (gram) of seawater. Organic carbon held in soil is eventually returned to the atmosphere through the process of respiration carried out by heterotrophic organisms, but a substantial part is retained in the soil in the form of soil organic matter; tillage usually increases the rate of soil respiration , leading to the depletion of soil organic matter. Since plant roots need oxygen, aeration

16720-411: The opening of the adjacent regional shopping centre (now Westfield West Lakes). The first inflow of ocean water was unscreened, causing a larger and more diverse influx of marine life into the lake. A large stingray was sighted in the lake, which was incorrectly reported to have been a shark. Due to the lake's intended recreational function, which included swimming and diving, larger marine life — such as

16872-422: The original West Lakes development. In contrast, it is a much denser urban environment that reflects contemporary urban planning practices — namely, smaller block sizes, functional public reserves, and a dominant presence of attached housing. The subdivision also features a City of Charles Sturt library , retail and hospitality precinct, a childcare centre, and an aged care facility . A small ornamental lake

17024-635: The other cations more weakly bound to colloids are pushed into solution as hydrogen ions occupy exchange sites ( protonation ). A low pH may cause the hydrogen of hydroxyl groups to be pulled into solution, leaving charged sites on the colloid available to be occupied by other cations. This ionisation of hydroxy groups on the surface of soil colloids creates what is described as pH-dependent surface charges. Unlike permanent charges developed by isomorphous substitution , pH-dependent charges are variable and increase with increasing pH. Freed cations can be made available to plants but are also prone to be leached from

17176-482: The outskirts of the city were generally inhabited by the very poorest. Due to the rapid migration of the rural poor to the industrializing cities of England in the late 18th century, a trend in the opposite direction began to develop, whereby newly rich members of the middle classes began to purchase estates and villas on the outskirts of London. This trend accelerated through the 19th century, especially in cities like London and Birmingham that were growing rapidly, and

17328-492: The plant roots release hydrogen ions to the solution. CEC is the amount of exchangeable hydrogen cation (H ) that will combine with 100 grams dry weight of soil and whose measure is one milliequivalents per 100 grams of soil (1 meq/100 g). Hydrogen ions have a single charge and one-thousandth of a gram of hydrogen ions per 100 grams dry soil gives a measure of one milliequivalent of hydrogen ion. Calcium, with an atomic weight 40 times that of hydrogen and with

17480-486: The porous lava, and by these means organic matter and a finer mineral soil accumulate with time. Such initial stages of soil development have been described on volcanoes, inselbergs, and glacial moraines. How soil formation proceeds is influenced by at least five classic factors that are intertwined in the evolution of a soil: parent material, climate, topography (relief), organisms, and time. When reordered to climate, relief, organisms, parent material, and time, they form

17632-414: The processes carried out in the soil, with effects ranging from ozone depletion and global warming to rainforest destruction and water pollution . With respect to Earth's carbon cycle , soil acts as an important carbon reservoir , and it is potentially one of the most reactive to human disturbance and climate change . As the planet warms, it has been predicted that soils will add carbon dioxide to

17784-509: The project’s impact on its environment and the quality of life of its occupants and neighbours. A sign announcing the award was displayed at the corner of West Lakes Boulevard and Frederick Road until the 2010s. It was removed around the time earthworks commenced for the WEST subdivision, with its current whereabouts unknown. The development phase of the West Lakes scheme spanned from 1970 to 2001, for

17936-523: The railway. However, World War I (1914–1918) delayed these plans until 1919, when, with the expectation of a postwar housing-boom, Metropolitan Railway Country Estates Limited (MRCE) formed. MRCE went on to develop estates at Kingsbury Garden Village near Neasden , Wembley Park , Cecil Park and Grange Estate at Pinner and the Cedars Estate at Rickmansworth and to found places such as Harrow Garden Village . The Met's marketing department coined

18088-414: The rate of diffusion of gases into and out of soil. Platy soil structure and soil compaction (low porosity) impede gas flow, and a deficiency of oxygen may encourage anaerobic bacteria to reduce (strip oxygen) from nitrate NO 3 to the gases N 2 , N 2 O, and NO, which are then lost to the atmosphere, thereby depleting the soil of nitrogen, a detrimental process called denitrification . Aerated soil

18240-442: The seat of interaction networks playing a decisive role in the stability, dynamics and evolution of soil ecosystems. Biogenic soil volatile organic compounds are exchanged with the aboveground atmosphere, in which they are just 1–2 orders of magnitude lower than those from aboveground vegetation. Humans can get some idea of the soil atmosphere through the well-known 'after-the-rain' scent, when infiltering rainwater flushes out

18392-550: The site will be converted into a pub , forming part of a broader retail and hospitality " high street " within the development. The development came about as the result of a major metropolitan land release and rezoning announcement by the state government in January 2024. The former wastewater treatment site was of particular interest for housing due to its relative proximity to the Osborne Naval Shipyard , where submarines for

18544-441: The soil anion exchange capacity. The cation exchange, that takes place between colloids and soil water, buffers (moderates) soil pH, alters soil structure, and purifies percolating water by adsorbing cations of all types, both useful and harmful. The negative or positive charges on colloid particles make them able to hold cations or anions, respectively, to their surfaces. The charges result from four sources. Cations held to

18696-538: The soil by volatilisation (loss to the atmosphere as gases) or leaching. Soil is said to be formed when organic matter has accumulated and colloids are washed downward, leaving deposits of clay, humus , iron oxide , carbonate , and gypsum , producing a distinct layer called the B horizon. This is a somewhat arbitrary definition as mixtures of sand, silt, clay and humus will support biological and agricultural activity before that time. These constituents are moved from one level to another by water and animal activity. As

18848-420: The soil solution composition (attenuate changes in the soil solution) as soils wet up or dry out, as plants take up nutrients, as salts are leached, or as acids or alkalis are added. Plant nutrient availability is affected by soil pH , which is a measure of the hydrogen ion activity in the soil solution. Soil pH is a function of many soil forming factors, and is generally lower (more acidic) where weathering

19000-402: The soil solution. Both living soil organisms (microbes, animals and plant roots) and soil organic matter are of critical importance to this recycling, and thereby to soil formation and soil fertility . Microbial soil enzymes may release nutrients from minerals or organic matter for use by plants and other microorganisms, sequester (incorporate) them into living cells, or cause their loss from

19152-473: The soil voids are saturated with water vapour, at least until the point of maximal hygroscopicity , beyond which a vapour-pressure deficit occurs in the soil pore space. Adequate porosity is necessary, not just to allow the penetration of water, but also to allow gases to diffuse in and out. Movement of gases is by diffusion from high concentrations to lower, the diffusion coefficient decreasing with soil compaction . Oxygen from above atmosphere diffuses in

19304-430: The soil water solution will be insufficient to change the pH, as the acid forming cations stored on the soil colloids will tend to restore the original pH condition as they are pushed off those colloids by the calcium of the added lime. The resistance of soil to change in pH, as a result of the addition of acid or basic material, is a measure of the buffering capacity of a soil and (for a particular soil type) increases as

19456-433: The soil water solution: Al replaces H replaces Ca replaces Mg replaces K same as NH 4 replaces Na If one cation is added in large amounts, it may replace the others by the sheer force of its numbers. This is called law of mass action . This is largely what occurs with the addition of cationic fertilisers ( potash , lime ). As the soil solution becomes more acidic (low pH , meaning an abundance of H ),

19608-462: The soil where it is consumed and levels of carbon dioxide in excess of above atmosphere diffuse out with other gases (including greenhouse gases ) as well as water. Soil texture and structure strongly affect soil porosity and gas diffusion. It is the total pore space ( porosity ) of soil, not the pore size, and the degree of pore interconnection (or conversely pore sealing), together with water content, air turbulence and temperature, that determine

19760-502: The soil, a complex feedback which is exemplified in the dynamics of banded vegetation patterns in semi-arid regions. Soils supply plants with nutrients , most of which are held in place by particles of clay and organic matter ( colloids ) The nutrients may be adsorbed on clay mineral surfaces, bound within clay minerals ( absorbed ), or bound within organic compounds as part of the living organisms or dead soil organic matter. These bound nutrients interact with soil water to buffer

19912-414: The soil, possibly making the soil less fertile. Plants are able to excrete H into the soil through the synthesis of organic acids and by that means, change the pH of the soil near the root and push cations off the colloids, thus making those available to the plant. Cation exchange capacity is the soil's ability to remove cations from the soil water solution and sequester those to be exchanged later as

20064-471: The stingray — were captured by professional divers and removed. Today, only smaller marine life is able to flow into the lake from the ocean, with designated fishing spots marked around the lake for recreational fishers. Due to polluted stormwater runoff into the lake, it's recommended to avoid prolonged contact with the water (e.g. swimming) for 2–3 days after rain. The boating lake was constructed with an international-standard rowing course in mind, and

20216-409: The strength of anion adhesion is as follows: The amount of exchangeable anions is of a magnitude of tenths to a few milliequivalents per 100 g dry soil. As pH rises, there are relatively more hydroxyls, which will displace anions from the colloids and force them into solution and out of storage; hence AEC decreases with increasing pH (alkalinity). Soil reactivity is expressed in terms of pH and

20368-579: The suburbs was facilitated by the development of zoning laws, redlining and numerous innovations in transport. Redlining and other discriminatory measures built into federal housing policy furthered the racial segregation of postwar America–for example, by refusing to insure mortgages in and near African-American neighborhoods. The government's efforts were primarily designed to provide housing to White middle-class and lower-middle-class families. African Americans and other people of color largely remained concentrated within decaying cores of urban poverty creating

20520-971: The term Metro-land in 1915 when the Guide to the Extension Line became the Metro-land guide, priced at 1 d . This promoted the land served by the Met for the walker, visitor and later the house-hunter. Published annually until 1932 (the last full year of independence for the Met), the guide extolled the benefits of "The good air of the Chilterns", using language such as "Each lover of Metroland may well have his own favorite wood beech and coppice — all tremulous green loveliness in Spring and russet and gold in October". The dream as promoted involved

20672-568: The tidal lake, in addition to its relative position within metropolitan Adelaide. It was formalised under the West Lakes Development Act 1969. Development earthworks commenced in September 1970, with approximately 10 million tonnes of earth shifted to form the tidal lake and create developable land. Due to the suburb being built on reclaimed marshland, particular consideration went into the engineering and construction of houses. During

20824-491: The two concentrations are equal, they are said to neutralise each other. A pH of 9.5 has 10 moles hydronium ions per litre of solution (and also 10 moles per litre OH ). A pH of 3.5 has one million times more hydronium ions per litre than a solution with pH of 9.5 ( 9.5 − 3.5 = 6 or 10 ) and is more acidic. The effect of pH on a soil is to remove from the soil or to make available certain ions. Soils with high acidity tend to have toxic amounts of aluminium and manganese . As

20976-510: The underground pipe, where an automatic hydraulic gate opens. At low tide, that same gate shuts as the lake reaches its highest level, and at the northern end of the lake, an automatic outlet gate opens allowing water to flow through to the Port River . This system results in approximately 410 megalitres of fresh seawater flushing the lake daily. The lake began filling in November 1974, in time for

21128-405: The upper classes. In the illustrative case of Rome, Italy, in the 1920s and 1930s, suburbs were intentionally created ex novo to give lower classes a destination, in consideration of the actual and foreseen massive arrival of poor people from other areas of the country. Many critics have seen in this development pattern (which was circularly distributed in every direction) also a quick solution to

21280-473: The void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining. Resistivity refers to the resistance to conduction of electric currents and affects the rate of corrosion of metal and concrete structures which are buried in soil. These properties vary through the depth of a soil profile, i.e. through soil horizons . Most of these properties determine

21432-553: The water content of the soil, as can be expressed in terms of volume or weight—can be based on in situ probes (e.g., capacitance probes , neutron probes ), or remote sensing methods. Soil moisture measurement is an important factor in determining changes in soil activity. The atmosphere of soil, or soil gas , is very different from the atmosphere above. The consumption of oxygen by microbes and plant roots, and their release of carbon dioxide, decreases oxygen and increases carbon dioxide concentration. Atmospheric CO 2 concentration

21584-461: The weathering of lava flow bedrock, which would produce the purely mineral-based parent material from which the soil texture forms. Soil development would proceed most rapidly from bare rock of recent flows in a warm climate, under heavy and frequent rainfall. Under such conditions, plants (in a first stage nitrogen-fixing lichens and cyanobacteria then epilithic higher plants ) become established very quickly on basaltic lava, even though there

21736-476: The whole soil atmosphere after a drought period, or when soil is excavated, a bulk property attributed in a reductionist manner to particular biochemical compounds such as petrichor or geosmin . Soil particles can be classified by their chemical composition ( mineralogy ) as well as their size. The particle size distribution of a soil, its texture, determines many of the properties of that soil, in particular hydraulic conductivity and water potential , but

21888-467: The wider sense noted in the lead paragraph) have become formalized as geographic subdivisions of a city and are used by postal services in addressing. In rural areas in both countries, their equivalents are called localities (see suburbs and localities ). The terms inner suburb and outer suburb are used to differentiate between the higher-density areas in proximity to the city center (which would not be referred to as 'suburbs' in most other countries), and

22040-410: The wider suburb. Notably, West Lakes was also one of the first urban developments in South Australia to feature underground power and telephone lines. Encumbrances also placed restrictions on the positioning and appearance of external fixtures (such as clotheslines , outbuildings, and TV aerials ) as well as a total ban on front boundary fencing . West Lakes was officially opened on 18 March 1977 by

22192-574: Was allowed to retain such land that it believed was necessary for future railway use. Initially, the surplus land was managed by the Land Committee, and, from the 1880s, the land was developed and sold to domestic buyers in places like Willesden Park Estate, Cecil Park, near Pinner and at Wembley Park. In 1912 it was suggested that a specially formed company should take over from the Surplus Lands Committee and develop suburban estates near

22344-541: Was also constructed as part of the subdivision. Not connected to the aforementioned tidal lake, it relies on mechanical surface aerators for water flow and oxygenation.
