assignment/short description

The city of St. Petersburg, with 5 million inhabitants, is located in the delta of the Neva River at
the eastern edge of Neva Bay. The city is nearly annually affected by floods (storm surges)
initiating from the Baltic Sea, which travel eastwards through the Gulf of Finland, to Neva Bay,
and finally inundate the city.
Since 1992, the city of St. Petersburg has been eager to complete the partially constructed
St. Petersburg Flood Protection Barrier. The Ministry of Finance of the Russian Federation has
requested the European Bank for Reconstruction and Development (EBRD) to participate in the
funding of this project. As part of the feasibility study of the project, the EBRD required an
Environmental Impact Assessment (EIA) to be conducted. A NEDECO consortium with Deltares /
Delft Hydraulics as leading partner, together with the Finnish Environmental Institute, was
selected to conduct the study.
