Amendment to the Protection Zone Law of Latvia is studied and compared with the likelihood of the flood risk and development possibilities in the flood risk zones. The study focuses on the case of the Vecdaugava River neighbourhood as the potential flood risk zone in Riga city.

Analizuojami Latvijos Respublikos apsaugos zonų įstatymo pakeitimai, potvynio rizikos galimybės tam tikrose zonose.

Highlights
Definition of the flood risk – the probability of flood and of the potential adverse consequences for human health, the environment, cultural heritage and economic activity caused thereby (Water Management Law 2002).The flood risk problem has become topical due to climate change and global warming, resulting in water level rise in the World Sea
Research results of Ltd PAIC (Rīgas pilsētas... 2010: 10) forecast an increase in the water level rate in Riga city reaching 3.6 mm per year, which is close to that foreseen in the Intergovernmental Panel on Climate Change (IPCC) prognoses
There are a lot of examples in Riga city, where the officials of the city should pay attention to the flood risk problems, especially during and after the storm time
Summary
Definition of the flood risk – the probability of flood and of the potential adverse consequences for human health, the environment, cultural heritage and economic activity caused thereby (Water Management Law 2002). The IPCC scenario A1B predicts an increase of water level with the rate of 4.8 mm per year This is the reason why various countries are changing their legislation related to flood risk (Eiropas Kopienu Komisija 2006). The weather conditions in the North part of Europe are similar to Latvia, European countries next to the North Sea are exposed to high and low tide daily In these territories flood risk may combine with wind storms. Research question: Impact of amendments to the Protection Zone Law of Latvia increasing the allowed index of flood risk in development areas from 1% to 10% on the spatial environment planning of Latvia, Riga city and the Vecdaugava River neighbourhood case
