Scope of the urban sprawl challenge Flashcards
describe the extent of urban sprawl
Perth is ranked among the world’s most liveable cities and holds the record for the longest suburban sprawl globally.
The metropolitan area includes the Peel region and is divided into 33 Local Government Areas with over 350 suburbs.
The urban boundary stretches from Two Rocks in the north to Dawesville in the south, with a drive of about two hours from end to end.
describe the growth of urban sprawl
Population and size of Perth have more than doubled since the 1970s, with a population increase of over 400,000 between 2010 and 2022.
Recent projections suggest a population of around 2.4 million by 2031 due to COVID-19’s impact, aiming for over 3.5 million after 2050.
Growth has been prominent in southeast, southwest, and northwest corridors, driven by areas like Ellenbrook, Baldivis, and Forrestdale.
describe Dwelling density and block size
High-density areas are concentrated in central northern suburbs, reflecting urban consolidation policies.
Dwelling sizes have reduced significantly, with lot sizes dropping from 626-709 sqm in 1999 to 399 sqm in 2022.
Increased density in greenfield areas has led to the decline of Australian backyards, impacting suburban density distribution.
Despite some progress, Perth’s expansion into natural and agricultural lands poses challenges for infrastructure and amenity improvement.
what is Urban sprawl
refers to the outward spread of typically low density residential and uirban development on the periphery of urban areas.
what is greenfield development
development that occurs on the undeveloped land in an urban or rural area that has been used for either agriculture or has evolved naturally
Urban consolidation
the process of increasing the density of housing and land use within a developed area, with the aim of reducing the need to develop on the fringe areas if a city.
urban sprawl of perth
Perth comes as low density detached dwellings and greenfield development on the urban fringes. Although elongated, semi stellate urban form, which has developed predominately along the coastline and transport corridors , offers lifestyle opportunities and lower construction coasts to residents.
