No person shall stop, stand or park a vehicle within an alley except during the necessary, active, and expeditious loading or unloading of merchandise, supplies or materials. Such loading or unloading shall not exceed twenty (20) minutes. If the stopping, standing, or parking of a vehicle within an alley would prevent the passage of an emergency vehicle or blocks the driveway or entrance to any abutting property, the vehicle shall remain attended at all times. In addition to the issuance of a notice of parking violation, violations of this section may result in the immediate impound of a vehicle that impedes safe passage or poses a threat to public safety.
