The regression-based SMCs included in this dataset are used to describe approximate and continuous relationships between watershed area and floodplain width. These are intended to be a starting point for planning purposes only, with refinement occurring through project design. <\/div>

<\/div>
The regression relationships are based on watershed specific floodplain (valley bottom) data; however, given the approach, they will not account for human-made structures or local geomorphic variability. They are not to be construed or used as a regulatory tool.  Further, floodplain and valley bottom widths within urban areas that reflect the broader geomorphic floodplain are inherently difficult to ascertain; therefore, the linkage between topographic data and floodplain widths in channelized streams is limited and will require refinement over time.<\/div>", "portalUrl": "" }
