Urban Land Value (Leaving Cert Geography): Revision Notes
Urban Land Value
Urban land values demonstrate significant variation across different areas of a city. Understanding these patterns helps explain why certain land uses locate where they do and how cities develop their characteristic spatial structure.
What determines urban land values?
Land values in urban areas are fundamentally shaped by two key factors: proximity to the Central Business District (CBD) and accessibility. The CBD represents the economic centre of the city, making land closest to it the most costly. As distance from the CBD increases, land values generally decrease, creating a predictable spatial pattern.
Bid rent refers to the maximum amount that individuals or businesses are willing to pay for land in a particular location. This concept helps explain how land values are determined through competition between different users.
The bid rent curve
The bid rent curve illustrates how different land uses compete for space at varying distances from the CBD. This curve shows that retail activities can afford to pay the highest rents close to the city centre, followed by manufacturing, and then residential uses. Each land use has a different ability to pay rent based on the profits or benefits they can generate from that location.
The curve demonstrates why we see distinct zones of land use radiating outward from the CBD - each activity locates where it can afford the rent whilst still operating profitably.
Retail and commercial land use
The most valuable location within the CBD is known as the Peak Land Value Intersection (PLVI). This represents the single most expensive piece of land in the entire urban area, typically found where major transport routes converge and pedestrian traffic is heaviest.
Peak Land Value Intersection (PLVI) is the area with the greatest commercial value, usually located at the heart of the CBD where accessibility is at its maximum.
Large department stores and major retail chains occupy these prime locations because they can generate sufficient revenue from high customer volumes to justify paying premium rents. These businesses often construct multi-storey buildings to maximise their use of expensive land.
Moving away from the CBD, shops tend to become smaller because they cannot afford the same high rents. With reduced accessibility and lower passing trade, businesses further from the centre experience decreased revenues, making high bid rents unsustainable.
Office locations
Office-based businesses follow different locational patterns compared to retail activities. Since offices don't depend on passing pedestrian traffic to the same extent as shops, they can afford slightly less accessible locations whilst still benefiting from CBD proximity.
Many offices locate on upper floors of buildings within the CBD or around the edges of the central area. Professional services such as law firms, accountants, and medical practices often choose these locations because they need to be accessible to clients but don't require ground-floor shop frontages.
Industrial land use patterns
Manufacturing and industrial activities have undergone significant locational changes over recent decades. Historically, many industries were located near the CBD, but modern industrial requirements have pushed these activities towards urban peripheries.
Contemporary factories require large sites for production, storage, and distribution facilities. Such extensive land areas are more readily available and considerably more affordable on the outskirts of cities. Additionally, industrial activities benefit from locations close to ring roads and motorways, which provide efficient access for freight transport whilst avoiding congested inner city areas.
Real-World Example: Industrial Location Patterns
The Sandyford Industrial Estate in south Dublin exemplifies this pattern, offering modern industrial facilities with excellent transport connectivity. Some industries have also located in renewed urban areas, such as the Dublin Docklands, where former industrial sites have been redeveloped for new economic activities.
Suburban land values
As urban populations expand, suburban areas experience increased development pressure and rising land values. The most valuable suburban land typically occurs where major transport links intersect, as these locations offer convenient access to the city centre.
Independent commercial areas, sometimes called multiple nuclei, develop in these well-connected suburban locations to serve growing local populations.
Examples of Suburban Commercial Development
Blanchardstown and Liffey Valley demonstrate how the presence of skilled workers has made these areas attractive for both residential development and modern industrial estates, including facilities in Sandyford and Santry.
The increasing concentration of skilled workers in suburban areas creates a positive feedback effect - better amenities attract more residents, which increases land values and justifies further investment in infrastructure and services.
Remember!
Key Points to Remember:
- Land values are highest in the CBD and decrease with distance from the city centre
- Bid rent explains how different activities compete for land based on what they can afford to pay
- The Peak Land Value Intersection (PLVI) represents the most expensive land in the urban area
- Retail activities can pay the highest rents and therefore locate closest to the CBD
- Modern industry prefers suburban locations due to space requirements and transport accessibility
- Suburban land values increase where major transport routes meet, creating secondary commercial centres
