Planning Strategy to address the urban sprawl challenge– Urban infill Flashcards
what is Peel@3.5million
The State Government’s Perth and Peel@3.5million initiative aims to guide the growth of the Perth and Peel region into a compact, consolidated, and connected city that can accommodate 3.5 million people by 2050.
The plan builds upon the vision of Directions 2031 and Beyond and focuses on changing housing development patterns through long-term infill measures to create a consolidated city.
what are urban consolidation principles
Urban consolidation principles are outlined, emphasizing well-designed, higher-density developments that consider local context, natural environment, and changing demographics.
what does urban infill mean
Urban infill involves developing within existing urban areas, including disused industrial sites, under-utilized properties, and vacant buildings, to make better use of developed areas and reduce housing spread on the city’s edge.
what does the plan proposes
The plan proposes that 47% of the additional 1.5 million people expected by 2050 will be housed through urban infill within established areas, mainly within the inner sub-region of Perth.
what are R codes
R-Codes are regulations indicating the density of dwellings allowed on a certain land size; higher R-Codes allow for greater density. They were introduced in the 1970s and have evolved to suit area characteristics.
what is infill development dominanted by
Infill development is dominated by high-density apartment projects and ‘build and replace’ developments where one dwelling is replaced by two, leading to increased density but potential challenges in local amenity, transport infrastructure, and affordability.
what are the environmental inpacts
Smart urban infill can reduce environmental impacts by limiting land clearing and habitat fragmentation.
Since 2010, there’s been a 40% reduction in land clearing on urban fringes.
Despite the benefits, only 47% of the target infill development was achieved in 2020, leading to more dwellings on the urban fringe than in infill areas.
what are some environmental issues with infill
Many infill developments have been criticized for poor design, decreased privacy, and reduced canopy cover.
These design flaws in infill areas can amplify environmental impacts despite the strategy’s intent.
economic factors
Implementing the strategy can save the government $94.5 million per 1,000 lots developed in inner urban areas, given the reduced infrastructure costs.
Businesses can potentially see increased revenue due to enhanced productivity from reduced congestion.
Urban infill can decrease long-distance work trips by about a third, reducing daily trips from 400,000.
Infill near key centres and train stations encourages residents to live and work locally, minimizing travel needs
Despite these advantages, urban infill hasn’t increased housing affordability due to limited housing diversity
social factors
Urban infill can offer affordable housing options but should enhance area quality, amenity, and value for community sustainability.
A comparison exists between densely populated Tuart Hill which has experienced much background infill and the affluent coastal suburb of City Beach
Early and active public engagement can address concerns and clarify the vision of infill developments.
what are some social concerns with infill
There’s community opposition in Perth, fearing infill might deplete green spaces and remove the unique character of suburbs.
Concerns also include increased traffic, parking issues, and potential property value drops, especially in western suburbs like City Beach and Nedlands.
livability factors
Liveability examines a community’s quality of life in relation to its natural and built environments.
The debate in Perth leans towards “infill good, sprawl bad.”
Background infill has brought varied liveability results, especially in middle-ring suburbs 5-15 km from the CBD.
Traditional infill projects, with long driveways and fewer trees, have been met with industry and community resistance.
