It is a tool for addressing overspill parking from neighboring population centers (such as a shopping center, office building, apartment building, transit station, stadium, or central business district).
The area has an approximate population of 10,000 people and has a distinctly modern residential character stemming from its history as a postwar overspill estate.
This is reflected in increased property valuations, and slightly higher spending than in 20th century overspill estates which tended to line the estuary.
Overspill parking is commonplace near shops, schools, hospitals, sports grounds and train/metro stations and at other locations that attract people and vehicles.
