These Professional Practice Guidelines – Legislated Flood Assessments in a Changing Climate in BC were commissioned by the British Columbia (BC) Ministry of Forests, Lands, Natural Resource Operations, and Rural Development (MFLNRORD). They were written to guide professional practice for flood assessments, identify the circumstances when Risk Assessments are appropriate, and emphasize the need to consider climate change and land use changes in such assessments. MFLNRORD and Engineers and Geoscientists BC assembled a team of specialists from government and the engineering and geoscience community to prepare and review these guidelines. The goal is that the application of these guidelines will result in consistent and comprehensive Flood Assessment Reports being submitted to government authorities.
