Spatial domainPima County
AbstractErosion hazard setback areas derived from the washes layer. Washes where buffered based on CFS value. Areas of constructed channel are limited to channel width.
Known errors/qualificationsThis layer should be considered only an estimate of the Erosion Hazard Setback, actual setback distances are measured from the top of bank.

Maintenance descriptionThe automated script performs the following steps:
1)Erase wash lines in constructed channels and federal lands.
2)Buffer wash lines by the erosion hazard setback value defined in the wash layer.
3) Merge constructed channels from the Drainage Maintenance layer.
4)Convert to raster and back to polygon in order to dissolve the resulting feature class.
