What does b4 zoning mean?

The B4 zone hopes to promote a 'live-work' environment by providing for higher density residential development integrated with a range of retail, business, light industrial and community uses. The revitalisation of the Kirrawee town centre is dependent on the integration of development in this zone. The B-4, Central Business District is intended to provide an area for the focus of the city, in which the full range of commercial and business uses may locate in a limited area of high intensity uses, with the appropriate forms of physical development at a high density.
