In trying to determine the total contiguous stream length per landowner, I dissolved parcels by parcel owner name attribute and intersected these dissolved parcels with streams. However, dissolving by parcel owner doesn't include parcels located across the street (right-of-way) when 'Create multipart features' is unchecked since they don't share common edges; and when I do check 'Create multipart features', it creates the desired result across the street but also includes piecemealed parcels per owner that are spread out in space which are not considered contiguous. I was even thinking of modeling this somehow in Spatial Analyst. I'm using ArcGIS 10.1 with a basic license. Any ideas of how to achieve the desired result?
