  The aim of the paper is -in accordance with the goals of the research team called „ Sustainable Integrated Settlement And Regional Planning” within the project EFOP-3.6.1-16 – to compile a comprehensive expert material on smart city. In accordance with my personal assignments within the teamwork, I studied first of all how sustainable urban water management issues are managed in the corresponding smart city documents, how the smart city concept which is evidently one possible way of sustainable urban development involves the strategy of sustainable stormwater management along with the elements of green infrastructure which are the inevitable segment thereof. The basis of the study were Hungarian official methodological guides and one university textbook published so far in the topic. Contrarily to the expected results the two notions of smart city and sustainable urban water management are not harmonized despite their common overall goals.  Therefore I make a few suggestions in order to harmonize to some extent the criteria and indicators developed for the two notions - smart city and sustainable urban water management including green infrastructure - promoting sustainable cities. The overall goal is to ensure that green infrastructure is not neglected while smart cities are realized.

  As urbanization accelerates, parking lots lead to stormwater runoff and localized flooding due to impervious layers and inefficient drainage. This case study evaluates stormwater management strategies across four parking lots in Debrecen, Hungary, to propose effective retrofitting solutions. The methodology combines visual site assessments with a comparative analysis of global best practices identified in the literature. Findings suggest integrating Green Infrastructure (GI) and Low Impact Development (LID) principles into parking lot design can enhance infiltration and significantly reduce surface runoff. Key recommendations include utilizing nearby vegetated depressions and replacing conventional concrete slabs with permeable surfaces. Beyond the flood avoidance, these strategies aim to reduce pressure on the local sewer system and minimize puddle formation.

  Green infrastructure measures improves the quality of surface and subsurface waters along with increasing the water balance on the town level. The aim of the study is to estimate the potential runoff quality improvement by applying stormwater BMP-s along traffic roads in the town. This is of high priority in the aquifer protection area where runoff water may infiltrate into the aquifer carrying pollutants from the surface. Estimations are applied: first we determine the surface of traffic roads, then estimate the quantity of different kinds of pollutants accumulated on the surface and thirdly we estimate the expected performance of the applied green infrastructure elements based on findings in the literature. We determine the impervious urban surface area associated with transport-related functions within the protected drinking water recharge area using GIS technic using orthophotos. We estimate the expected reduction of runoff pollution assuming that stormwater BMP-s are applied in the area. The overall goal is to make the significance of diffuse pollution more obvious and enhance drinking water protection through taking diffuse pollution into consideration.
