Abstract: The study presents approaches to designing of the Automated Control Systems (ACS) for management of the environmental safety of the local urban areas (the natural environment of which has a significant effect on the human health and activities). The operation of such ACSs is based on the synthesis of the intelligent environmental monitoring and intelligent support of the decision-making process. There have been proposed the structural model of the ACS subsystem implementing the functions of the decision support and the method of performing the integrated (complex) assessment of the existing and forecast environmental situation on the territories under consideration. The implementation of such ACSs will promote to the development of the modern cities based on the principles of biospheric compatibility, increase in the efficiency of managerial decisions in the area of environmental safety and as a result to the improvement of the human life quality.
