    widen bridge vs detention

    a concrete bridge is widened with one more lane, and Reviewer comments we should consider about mitigation (detention) due to increased impervious area, but we don’t agree with it because this is a dry bridge (crossover) and the land (road under this bridge) is developed. What do you think?
