Erosion 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/Qualifications: This layer should be considered only an estimate of the Erosion Hazard Setback, actual setback distances are measured from the top of bank.
Spatial Domain: Pima County
Maintenance Organization: RFCD
Maintenance Description: The 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.
Maintenance Frequency: Quarterly
