Symbolize polygon using 7 fields

Hello -

I have a building layer that has 7 fields indicating the depth of flooding for each modeled design storm (1-yr, 2-yr, 5-yr, 10-yr, 25-yr, 50-year, and 100-yr). I would like to symbolize the layer based upon which design storm a building first begins to flood (depth>0). So for example, if depth at the 1-year <=0, depth at the 2-year<=0, but at the 5-year depth>0, then it would be symbolized as "5-Year". The symbology categories would be: 1-year, 2-year, 5-year, 10-year, 25-year, 50-year, 100-year. Is it possible to do something like this using an arcade expression without creating a new permanent field in my layer? I am working in Pro 3.3 and will publish the service to Portal.

Thanks in advance.

Leila

You can certainly use Arcade for this. Check out the function When:

return When( $feature['1-year'] > 0, '1-year', $feature['2-year'] > 0, '2-year', $feature['5-year'] > 0, '5-year', $feature['10-year'] > 0, '10-year', $feature['25-year'] > 0, '25-year', $feature['50-year'] > 0, '50-year', $feature['100-year'] > 0, '100-year', 'No Value' )

Conditions evaluate in order, so by checking which field is greater than 0 in this order, as soon as one of the conditions evaluates as true, it returns the corresponding string.
