It seems like this is the case, and part of the road is spelled Kuckup and part is spelled Kuchup. 

Looking at the Oregon state GIS for this area, it's quite odd. For example, Hollywood Blvd cuts across the grass and connects to Kot-Nam Road, which is clearly not the case on any imagery.

It also has a number of other discrepancies which make me not want to trust it for updating the road names here. I think unfortunately unless we get more data, a survey will have to be done on the street names (if there are signs), or someone will have to contact the city.
