The article discusses the possibility and perspectives of using the reclaimed artificial areas in the coastal zone of marine estuaries for the sustainable development of urban infrastructure and creation of modern architectural ensembles with the background of green economy using the example of Lakhta-Center on the northern coast of the Neva Bay (St. Petersburg, Russia). The geo-ecological stability of underwater and coastal landscapes of the coastal zone of the Neva Bay is analyzed using side scan sonar. The environmental sensitivity of coastal ecosystems is estimated. The received data can be used on practice for planning the construction work and for the development of the infrastructure of urbanized coastal zone of the Neva Bay. The general geo-ecological situation in the observed area is rather stable. The coastal zone has good perspectives for the development of a sustainable urban infrastructure against the backdrop of the green economy. The special attention should be paid to migration of birds and fish, who are using the North Lakhta coast as a temporary refugium during Spring and Autumn migrations. An effective solution from both environmental and economic points of view could be the organization of the Nature Conservation Reserve, which is spatially associated with the Lakhta Center zone. Such type of the complex using of the coastal zone could be a good example of the spatial planning in the environmentally sensitive area.

The paper presents important criteria for human health estimation in urbanized industrial areas. On the contrary, environmental and economic conditions are successfully identified on the basis of population’ elemental status. Cause-effect relations between micro and macro element consumption (lack or abundance) and public health in North-West Federal District of the Russian Federation have been established using the open press sources. Data capturing and visualization are made. Spatial digital maps presenting element consumption for non-personalized groups as well as their main disorders are obtained. The environmental situation in urbanized regions should be used to make future modeling possible for the purposes of a green economy. The paper demonstrates there al picture of availability of macro and micro elements, their lack or abundance. Maximum disease cases per 1000 people appear in the Republic of Karelia, and minimum is in the Leningradskaya Oblast. In practice, mercury abundance is a stimulating agent for most disorders of different origin, which primarily, for example, neoplasms and leukemia. Monitoring and correction of chronic toxic metal exposure at the individual and population levels can significantly reduce expenses on educational and medical services, increase labor efficiency.
