Here is the legal definition of a "driveway" in CA:

There is no requirement that there be curb cuts or anything else to be called a driveway.
All that section 22550(e) does is define when it can be cited and what helps define a driveway in an unincorporated area where it is less like to find clear curb delineations.
22500. No person shall stop, park, or leave standing any vehicle
whether attended or unattended, except when necessary to avoid
conflict with other traffic or in compliance with the directions of a
peace officer or official traffic control device, in any of the
(e) In front of a public or private driveway, except that a bus
engaged as a common carrier, schoolbus, or a taxicab may stop to load
or unload passengers when authorized by local authorities pursuant
to an ordinance.
In unincorporated territory, where the entrance of a private road
or driveway is not delineated by an opening in a curb or by other
curb construction, so much of the surface of the ground as is paved,
surfaced, or otherwise plainly marked by vehicle use as a private
road or driveway entrance, shall constitute a driveway.
490 is a definition, 22500 is enforcement.
Many municipalities (like mine) have a good number of curbs that are rounded. There is no difference between the curb in front of my house and the curb at the end of my driveway. The difference is that my driveway is clearly paved from the garage to the street. In this instance the OP will have a defense if he/she can show that the driveway was not all that obvious. If it is clearly a driveway to a reasonable person, then the OP will likely lose his/her appeal. If it looks no different than the front yard, then he/she might prevail.
Note that 22500(e) does not require that the city has to approve the area as a driveway, only that it is a place of private ownership used for vehicular travel by the owner. if the city has a zoning ordinance or code regulations against such a driveway, that can be raised as a separate issue.
So, for the OP to prevail, he/she needs to take copious photos and try to convince the hearing officer or panel that the driveway was not clearly designated as such. Unfortunately, as the OP has not contested the tow within the 10 day window, receiving compensation from the city for the tow may be difficult if not impossible. But, who knows.
