Bethlehem's older neighborhoods have mature trees planted decades ago along narrow streets, many of them now taller than the houses beside them. Large trees on small lots are exactly where removal gets complicated: there's little room to drop sections, so crews rely on rigging, and sometimes a crane parked on the street.
If a tree sits between the sidewalk and the curb, it may be a street tree under the city's control rather than yours, and the City of Bethlehem should be contacted before anyone cuts it. Bethlehem also spans both Lehigh and Northampton counties, so the contractor needs to know your exact address to sort out any permits. In your request, mention how close the tree is to the house and wires, and whether a vehicle can get into the yard. It saves an extra visit.
