• We use geomorphic surveys to quantify the differences between restored and nonrestored streams, and the difference between streams restored for market purposes (compensatory mitigation) from those restored for nonmarket programs. We also analyze the social and political‐economic drivers of the stream restoration and mitigation industry using analysis of policy documents and interviews with key personnel including regulators, mitigation bankers, stream designers, and scientists. Restored streams are typically wider and geomorphically more homogenous than nonrestored streams. Streams restored for the mitigation market are typically headwater streams and part of a large, complex of long restored main channels, and many restored tributaries; streams restored for nonmarket purposes are typically shorter and consist of the main channel only. Interviews reveal that designers integrate many influences including economic and regulatory constraints, but traditions of practice have a large influence as well. Thus, social forces shape the morphology of restored streams. Key Points: Restored streams are different Market streams are different Stream restoration design is a social process
