Land Use Outreach - Land Use Inquiry: Parcels Intersect zones along their boundary?

[LaurenLee]

Is there any way to have the zone look up ignore zones that only touch the boundary when it intersects. (I won't espouse that my topology between my parcel layer and zoning layer is perfect, but it has been adjusted recently). It makes it confusing to the public to see multiple zoning designations appear in the results. 

Something in the configuration? An arcade expression? Any ideas?

I would use Arcade to bring the zoning into the parcel popup, that's what we do. And we run the intersection based on the parcel's centroid, to avoid the edges.

var zoning = FeatureSetByName($map, 'zoning')

var xs = Intersects(
  Centroid($feature),
  zoning
)

if ( Count(xs) > 0 ) {
  return First(xs)['zoning_code']
}

 Mind you that a centroid may not actually be within a parcel if the shape is goofy. You can also do a negative buffer, like Buffer($feature, -10) to get a "shrunken" parcel, but that takes a bit more processing, where a centroid is nice and fast.
