Flood hazard maps should be used in land use planning to identify areas prone to flooding( should not be developed), and in order to assess relevant risk-reducing measures if it is impossible to avoid development.
Guidelines 2-2011 Flaum- og skredfare i arealplanar (Flood and avalanche risk in land use planning) describe how safety requirements for structures specified in the Regulations on technical requirements for building works (TEK 17), section 7-2 can be fulfilled in spatial planning.
When dealing with detailed zoning plans, division proceedings and processing building applications, it is necessary to take the limited accuracy of the flood hazard maps into account. In-situ measurements of elevation should be checked and compared to the calculated water levels.
If development is planned in areas prone to flooding, it is recommended to add a safety margin to the calculated water levels to take uncertainty in the data into account.
