One of the most important measures to reduce the risk of natural and natural-technological disasters is the engineering-geological mapping of the city area, carried out in accordance with a group of geological factors such as topography, formulation and properties of rocks, hydrogeological conditions, geodynamic processes development, etc. On the territory of the city of Novocherkassk as well as in other areas of urban settlements in the Rostov region, the active development of devastating processes associated with the extensive spread of clayey soils with low values of high strength characteristics and high water cutting groundwater arrays, caused by both natural active processes and technogenic influence. After the research conducted, it was decided that the area of the city of Novocherkassk is divided into zones of geological risk. Thanks to the mapping of the territory, it is allowed to make the right architectural and planning decisions and exploit it with well-executed investments, with security requirements.

Abstract: preventing the formation of ice on roofs and gutters of buildings appears to be socially and economically significant goal, requiring efficient and effective decision-making. Roof and gutters heating has the potential to avert the loss of life and vehicles damage due to falling icicles. The costly package of measures of manual cleaning of roofs, which often leads to unscheduled repairs of roof , gutters and facades of buildings is thus not needed. A competent choice of the way of heating is able to provide positive social and economic benefits for the city and must be done according to the availability of specific types of energy resources ... The article justifies the applicability of water heating system that runs in both automatic and manual control. Such systems allow the use of heat supplied by CHP local boiler or gas compact heater.

In this article the territory of the city of Rostov-on-Don is considered and engineering-geological conditions for the purpose of construction of buildings and constructions on a monolithic base plate of small laying are analysed. The schedule of dependence of the limit module of deformation on pressure under a base sole is constructed. The analysis of engineering-geological conditions in the city of Rostov-on-Don is made, and also the map and the chart of distribution of the average module of deformation in his territory are made.

Keywords: the average module of deformation, extreme draft of a subfoundation, pressure under a base sole, a monolithic base plate

To preserve the historical integrity of the city it is necessary to use individual approach to reconstruction in strict accordance with the rules of land use and development. Analysis of the housing stock the Central part of the city of Rostov-on-don was produced using data from the monitoring of its technical condition and showed that the Central part of Rostov-on-don residential buildings of old buildings, low rise and an unsatisfactory technical condition, proves the need for a comprehensive reconstruction. Over the past five years in the Central part of the city the construction of high-rise buildings in area of historic buildings, leading to disruption of its historic appearance.

For formation of favorable tourist image of the Rostov region it is necessary to pay special attention to an ecological situation in the region. The technique of organizational and technological actions for elimination of negative influence of factors of environment and to increase of recreational appeal of the territory is developed. Its application will allow to increase investment appeal of the territory in general, and also to improve quality of life of the population and to increase a tourist stream. Results are presented in the form of the tables and electronic cards constructed in the environment of ArcGIS ESRI. Use of GIS of technologies allows to supply the investor with necessary information on investment appeal of certain territories for an arrangement of tourist and recreational zones. Results of the carried-out work will allow to estimate any territory, to carry out the analysis of the received results and to receive a real picture in research of this or that territory.
