Q

characteristics of the CBD

A

Vertical zoning- shops and services occupy lower floors of building
low residential population- high rent; some luxury flats
absence of manufacturing - few specialised activities e.g. newspapers
concentration of offices- central location needed for clients and workforce
multi storey development- high land values encourage buildings to grow upwards
pedestrianisation- limited movement of vehicles; made shopping safer but some town centres have lost character
comprehensive redevelopment- extended into inner city causing conflict with residents; shift centre of cbd causing businesses to decline
concentration of retailing- dept stores and high threshold stores occupy the centre; specialist shops occupy less accessible sites
