   (c)   During the existence of the emergency, no person shall park or cause to be parked or permit to remain parked or shall abandon or leave unattended any vehicle on any street or portions thereof located within the City except such person, resident, owner or operator of a vehicle, having a residence abutting any street, parklane or alley having a width of twenty-five feet or less and providing no driveway facilities.
   (d)   Provided, however, that vehicles may be parked for a period of not longer than fifteen minutes for actual loading or unloading of passengers or property, and that snow removal equipment is not being operated on such street and that no other ordinance, prohibition or proclamation, restricting parking is violated thereby.
   (e)   Any motor vehicle parked in violation of this section is hereby declared to be a public nuisance and may be removed from the street and impounded at such place as may be directed by the Mayor, Commissioner of Engineering or Traffic Coordinator at the cost and expense of the owner thereof.
   (f)   No liability shall attach to the City or to the officer ordering the removal and storage of such vehicle in violation of this section or for damage caused thereto or resulting therefrom, and any person towing or storing the vehicle at the request of any member of the Police Department shall have a lien on the vehicle for the towing and storage charges incurred, such towing charges to be set by the Board of Control pursuant to competitive bidding.
