Urbanization is a probable global phenomenon through the expansion and densification of urban centres challenging the emergency fire service which is an essential public service for sustainable growth. Urban centres are experiencing an incremental rise in fire incidences vulnerably causing significant loss of life and property threatening sustainable development. Adequate provisions of fire service facilities are essential to ensure sustainability through life safety, property protection, continuity of operations, environmental protection, and heritage conservation. With the aim to assess sustainable urbanization with the adequacy of fire service provision, interpretations of benchmark assessment BMA are essential to identify the substantial service gaps for up-gradation in the fire service facility. The study assessed fire service availability, proximity, and service area gap using geoinformation technology adopting the GIS tool combined with statistical analysis contexting the case of the typical urban centre of Nagpur city. Response distance approach through Euclidean distance method is adopted along with the network analysis for the evaluation of the actual service area to assess spatial accessibility. Correlation analysis of response distance between the coverage area and the population size through periods fulfills the globally accepted response distance measure of 3 km. Normalization evaluation with ranking assessed the suitability of fire service provision within the city. The application of BMA methodology has the potential to estimate the deficit for the entire country at a fast pace with immediate implications, helping efficiently upgrading the NDMA requirement to build urban resilient infrastructure and in accord with Smart City Mission.
