Field tips

Land outside a subdivision

Before you lean on the lines
Parcel lines are drawn for taxes, not measured on the ground, so a tree line near Steelton can sit a few yards off the line on screen. Records update in batches, so a fresh transfer around Highspire may not show yet.
Where the recorded documents are
