The City of Helsinki can be seen administratively as a complex system and hierarchy, in which communication on sea level rise related issues is transferred from e.g. science to planning or technical infrastructure decisions to the city planning department...

The Vulnerability Assessment in Itä-Uusimaa was carried out by interviewing local and regional experts. The qualitative approach and theme interviews suited the meaning well since the topic is still quite new for many stakeholders. Also the development of the Vulnerability Assessment was easier because of the direct feedback...

The institutional coping capacity in Itä-Uusimaa is rather high. Local experts generally work closely together and have already established communication channels. This co-operation concerns the flood risk of today, not the future sea level rise...

The new Land Use and Building Act in Finland came into force in the year 2000. According to this Act more power was given to the local level and public participation in the planning process was emphasised...

The three different mean sea level surface height scenarios (high, medium and low case) for the Baltic Sea released by the SEAREG project for Itä-Uusimaa are: high - a sea level rise of 70-75 cm, medium - a rise of 20-25 cm and low – a drop of 22-27 cm due to the dominating land uplift up to year 2100...

Although having a long shoreline with countless islands, Helsinki lies on a relatively high elevation, thus in general being less susceptible to coastal flooding...

The winter storm of 8th-9th January 2005 served as a good example on the vulnerability of Helsinki in case of a storm surge. As the sea level reached a new record-height, a wide range of actors both had to show their abilities on minimizing the damage on a short-term basis and to engage themselves on a discussion on the lessons learned...

The topography of Helsinki in general makes the city little vulnerable towards flooding. Only few low-lying areas will experience a notable higher flood risk due to sea level rise...

In Helsinki sea level rise came first into discussion in 1989. As a result the lowest elevation level in Ruoholahti residential area was set to from 2 to 3 meters when newly built up in the 90's...

Finland has a border of 1100 kilometers in the Baltic Sea. The coastal waters are quite shallow and there are numerous islands, especially on the South-Western archipelago that alone has over 17 000 islands. Some 37% of the Finnish coastal shoreline is built up, mainly by summer cottages. (Granö et al., 1995.)..

This research employed spatial analysis tools in Geographic Information System (GIS) to evaluate the spatial extent of future flood prone areas in the two case study Cities Porvoo and Loviisa. A sum operation was run in the raster calculator to generate a flood prone area analysis with digital elevation model (DEM) and sea level results of the Regional Climate Model (RCM) as source data. ..
