*Geodatabase and its constituent feature classes are projected in NAD 83 Yukon Albers, because the project straddles multiple UTM zones.


MASS MOVEMENT FEATURE DATASET:

Mass_Movement_poly - lateral (2D) limits of existing and imminent, soil and/or rock mass movement geohazards with the potential to impact the highway; includes site- and feature-specific characteristics (field headings defined in Appendix A of report)

Mass_Movement_point - centroids of existing and imminent, soil and/or rock mass movement geohazard polygons (as above); includes site- and feature-specific characteristics (field headings defined in Appendix A of report)

Mass_Movement_LineFeatures - linear features (e.g., tension cracks) associated with the existing and imminent, soil and/or rock mass movement geohazards (as above)


MEANDER MIGRATION FEATURE DATASET:

MeanderEllipses - generalized area of encroachment between channel meander and highway, within which any future impact is most likely

Meander_points - general location of meander-highway encroachment site, for the purposes of overview figures

MeanderBankline_1977 - alignment of tops of channel banks based on georeferenced 1977 aerial photography

MeanderBankline_1989 - alignment of tops of channel banks based on georeferenced 1989 aerial photography
 
MeanderBankline_2013_2014 - alignment of tops of channel banks based on 2013/2014 orthophotography

Meander_Thalweg - estimated alignment of channel thalweg based on specific year of aerial photography

ExistingRiprapExtent - interpreted lateral extent of existing riprap, irrespective of condition, along channel banks immediately adjacent to the highway (at 26 prioritized meander-highway encroachment sites)

ImpactZoneExtent - projected lateral zone of impact due to continued channel/meander migration alongside the highway, without proactive intervention, which represents an estimated lateral extent of required riprap protection (or other stabilization measure)


COMMON FEATURE CLASS:

Field_Sites - locations and basic comments at each field inspection site, with reference to more detailed characterizations where applicable
