Which sides of a parcel have road frontage.

Discussion created by clm42 on Apr 10, 2013
Im trying to figure out how to find which 'side' of a land parcel has road frontage. The matter is complicated by our PA not storing true curves when they draw the parcels. Any cul-de-sac is made of hundreds of tiny lines each technically a side of the polygon. Ive converted polygons to lines and split at vertex but I cant figure out of the line fronts a road. I was thinking that if I can flag the segments as road front I could delete the other lines and merger the remaining back into longer lines by parcel ID. Any ideas on how to check this?
