Vulnerability Functions

The paper presents commonly used methodology for assessing damage of water supply networks after a seismic event. The methodology relies on deriving and applying so-called vulnerability function. An overview of the existing vulnerability functions is given together with parameters, primarily related to soil deformations, which are influencing the assessment. Also, a critical review of the possibility of their use is given. Finally, by using two approaches, the estimated number of damages, with associated repair costs, is given for the water supply network of the City of Petrinja after the earthquake on December 29, 2020. With a total of 3 800 new damages, it is estimated that the total repair costs are around HRK 28 million. The accuracy of these estimates should be verified after detailed collection and processing of relevant data in accordance with the given guidelines.

The paper deals with the issue of charging local authorities with the costs of realisation of the provisions contained in local spatial development plans in Wrocław (Poland). Considering the planned spatial development in the area of the city Wrocław, the urbanisation costs that are chargeable to the municipality budget were identified. The economic effects of preparing areas designated for development in the residential programme offer were analysed. The paper provides an analysis of the cost of realisation of investments that belong to own duties of the municipality, including the cost of building municipality roads, sewage and water supply networks, arranging public greenery and purchasing land for public investments. The analyses were performed within the administrative borders of the city.  The prognosed costs of the realisation of local spatial development plans demonstrate significant expenditure that Wrocław has to incur for the construction of sewage network and municipal roads. Additionally, the development of new areas will require the city of Wrocław to take over the real properties on which public goals are planned to be realised. One should thoroughly consider the actual need for new investment areas in the city. Demographic forecasts demonstrate that the areas designated for development significantly exceed the demand.
