Purpose – The purpose of the paper is to provide a robust and simple methodology for disaster risk management officials to assess the total disaster risk posed by dolomite in urban areas of South Africa. Design/methodology/approach – In order to develop the methodology the basic principles of disaster risk assessment, incapsulated in the notation R¼H V, was applied to provide a vehicle to quantify hazard and vulnerability aspects related to dolomite risk. Specifically existing knowledge on inherent dolomite risk classes (hazard component) was aligned to issues of vulnerability (in this case ageing water infrastructure) to attain a total dolomite disaster risk score for a specific area. Findings – The results from the practical application of the method indicated that the proposed dolomite risk assessment methodology is not only robust but easy to comprehend and to apply. The simplicity of the method also allows for easy integration into existing urban planning and integrated development planning process. Originality/value – The creation of the method not only provides a much-needed tool for assessing the total disaster risk posed by dolomite in urban areas but also adds value to the entire urban and community development process.
