The following regulations on permitted and required accessory off-street parking spaces are adopted in order to provide parking spaces off the streets for the increasing number of people driving to work in areas outside the high density central areas, to relieve congestion on streets in industrial districts, to help prevent all-day parking in residential and commercial areas adjacent to manufacturing areas, and to provide for better and more efficient access to and from industrial establishments within the City, and thus to promote and protect public health, safety, and general welfare.
