Polygons of proclaimed Landslip Areas in Tasmania, with reference to the Statutory Rules (government orders) under which these areas were declared. The Tasmanian Government has declared A Landslip and B Landslip areas (otherwise known as Proclaimed Landslip Areas) in parts of Tasmania under the authority of the Mineral Resources Development Act 1995 (sections 161A- 161D). These proclaimed areas are designed to prohibit or restrict building and other activities in particular areas of unstable land, as specified under the Building Act 2000 (Part 10 Division 1). In essence A Landslip areas are those where no more development is allowed, while B Landslip areas allow development with strict controls designed to protect the stability of both the underlying B Landslip area and adjacent A Landslip areas. Declaration of these areas is not undertaken regularly and only a relatively small number of areas exist, compared to the much greater area of land that can be considered as potentially unstable. Proclaimed Landslip Areas are proscriptive zones and quite different to advisory zones, such as those shown on the susceptibility maps in the Tasmanian Landslide Map Series.
