This paper presents a Proposed Method for Dolomite Land Hazard and Risk Assessment for characterising the potential stability of dolomite land, which is based on the Method of Scenario Supposition proposed by Buttrick and Van Schalkwyk (1995). The Proposed Method considers risk as well as hazard and reviews the classification of sites in terms of Dolomitic Area Designations as defined in the National Home Builders Registration Council's Home Building Manual (NHBRC 1999). The Proposed Method requires the evaluation of site geological conditions, provides a deductive framework within which professional judgement must be exercised, and offers a tool for the quantification and management of development risk. The provisions of the Housing Consumer Protection Measures Act (Act 95 of 1998) for the management of risk relating to housing development on dolomitic land are also presented.
