This report reviews how stream Crossing designers can account for the effects of climate change in small, remote watersheds by applying publicly available climate information tools — interactive maps that use or summarize projections of climate models that include historical and projection periods. It identifies five applicable tools for B.C., along with three approaches to using them by referencingapplicable professional engineering guidance and climate science developments. To compare tool outputs, the document référé nces a rainfall-regime flood case study location and provides calculations of the variable projections for percentchange to a Q100 event. Accounting for climate change on design floods at local scale requires a high level of professional judgment that includes decisions about which climate information tools to incorporate, interpreting their outputs, and considering climate change uncertainties relative to other uncertainties in historical Q100 calculations.
