Abstract
The authors of the article integrate legislative, cognitive-behavioural, and construction approaches to green infrastructure in the context of urban engineering involving green space as a fundamental attribute of quality of life. They briefly introduce the ideas of ideal cities of the geniuses of antiquity, Marco Vitruvius Pollio, Leonardo da Vinci, and Thomas More. The main focus is on the legislative issues of green infrastructure, particularly concerning the activities of local authorities. They perceive green infrastructure as an institute with a multi-beneficial meaning, within the framework of administrative science understood as a public interest incorporating a range of partial issues from the primary interest of environmental protection, economic development of settlements, promotion of public and mental health, social issues, and sports.
