1. This Regulation prescribes the content and type of the information to be provided in the preliminary flood risk assessment (hereinafter - assessment), the flood hazard maps, the flood risk maps and the flood risk management plan, as well as the additional information to be included upon updating the referred to documents.

II. Content and Type of Information to be Provided in the Assessment

2. The State limited liability company "Latvian Environment, Geology and Meteorology Centre" (hereinafter - Centre) shall carry out an assessment on the basis of the information available regarding layout of bodies of surface water and their hydrological and morphological characterisation, topographical plans and maps of adjacent territories, data on the planned (permitted) use of the area specified in the spatial plan, studies on the impact of climate changes on occurrence of floods and other corresponding information.

3. The following shall be included in the assessment:

3.1. a map of the river basin district including the catchment areas and borders of bodies of surface water (rivers, lakes or coastal areas), their topography, as well as the current and planned (permitted) use specified in the local government spatial plan;

3.2. a description of the floods which have occurred in the past and which had significant adverse impacts on human health, the environment, cultural heritage and economic activity or repetition of which would cause serious adverse effects, if measures for the prevention thereof are not implemented, a description of the extent and conveyance routes of such flood, as well as an assessment of the adverse impacts they have entailed;

3.3. a short analysis on the potential adverse consequences of future floods on human health, the environment, cultural heritage and economic activity, in addition to the information referred to in Paragraph 2 of this Regulation also taking into account the characteristics of the particular area subject to flood risk, the flooding areas specified in accordance with the Protection Zone Law - natural flood retention areas, the effectiveness of existing hydrotechnical flood defence structures, the position of populated areas and areas of economic activities;

3.4. textual and graphic flood risk analysis, also including agricultural polders and territories adjacent to hydroelectronic power stations and showing in the map such conclusions made regarding areas, in which flood risk exists or may occur.

[20 March 2012]

III. Content and Type of Information to be Provided in Flood Hazard Maps and Flood Risk Maps

4. The Centre shall prepare flood hazard maps and flood risk maps in digital form at certainty of scale no less than the certainty of local government spatial plan scale.

5. In the flood hazard maps the Centre shall indicate the areas subject to flood risk and a flood risk scenario:

5.1. floods with a low probability - extraordinary, extreme floods repeating once in 200 years or less often;

5.2. floods with a medium probability - floods repeating once in 100 years or less often;

5.3. floods with a high probability - floods repeating once in 10 years or less often.

6. The Centre shall indicate the following information in flood hazard maps for bodies of surface water, adjacent areas of which are subject to flood risk, regarding each flood risk scenario referred to in Paragraph 5 of this Regulation:

6.1. the size of the area subject to flood risk;

6.2. the average water depth or water level in the body of surface water;

6.3. where appropriate, the average water flow velocity or the relevant water flow.

7. The Centre shall indicate the potential adverse consequences of floods for each of the flood risk scenarios referred to in Paragraph 5 of this Regulation, taking into account the following parameters:

7.1. the indicative number of inhabitants potentially affected;

7.2. type of economic activity of the area potentially affected;

7.3. installations, in which the Category A polluting activities specified in Annex 1 to the Law On Pollution are carried out and flooding of which may cause environmental pollution or have adverse impact on human health;

7.4. the protected areas specified in the Water Management Law - water bodies which contain recreational objects or bathing waters, specially protected nature territories, as well as sources of water, which are used or are planned to be used for extraction of drinking water by more than 50 natural persons or in which the average amount of water extraction exceeds 10 m3 per day;

7.5. other significant information on the particular body of surface water - flood defence hydrotechnical structures and hydrotechnical structures regulating water level, areas where floods with a high content of transported sediments and debris floods can occur, as well as information on other significant sources of environmental pollution.

[20 March 2012]

8. The Centre shall prepare flood hazard maps for coastal areas, which are sufficiently well protected from the impact of floods, and areas, which overflow due to the rise of groundwater or during incessant rain, only for the flood risk scenario specified in Sub-paragraph 5.1 of this Regulation.

IV. Content and Type of Information to be Provided in the Flood Risk Management Plan

9. In conformity with the requirements specified in the Water Management Law, the Centre shall determine flood risk management objectives for areas, in which flood risk exists or may occur, for all the flood risk scenarios referred to in Paragraph 5 of this Regulation in order to reduce the flooding risk, the potential adverse impacts of floods on human health, the environment, cultural heritage and economic activity, as well as draw up a flood risk management plan (hereinafter - plan). The plan shall include measures for achieving such objectives, and it shall be integrated in the river basin management plan.

[20 March 2012]

10. Upon developing flood risk management objectives and plan, the characteristics of the catchment area of the particular body of surface water, the potential extent and conveyance routes of floods, the areas naturally retaining floods, for example, natural flood-lands, the environmental quality objectives specified in the river basin management plan in accordance with the Water Management Law, the management and use of areas subject to flood risk (including soil and water), the textural and spatial data of the spatial plan and of the information system of the Immovable Property State Cadastre, the environmental protection, the water transport and port infrastructure objects, as well as the approximate costs of the measures intended for achieving flood risk management objectives and the anticipated results thereof shall be taken into account.

[20 March 2012]

11. The plan shall cover all aspects of flood risk management, including preventive and preparedness measures that are directed towards prevention or reduction of flood risk, including flood forecasts and early warning systems. In selecting measures, controlled flooding of particular areas during floods and the preservation or restoration of natural regime in wetland areas, as well as other measures, which promote sustainable land use in the potentially flooding areas, may also be provided for.
