A family member has recently moved into a house that has a fairly
steep driveway from the street to the house garage. There is a "drywell"
at the bottom by the garrage door which seems to catch the majority of
rainwater, and street runoff, pretty well, but not all of it. Was
wondering if there's such a thing as, e.g., a rubber strip maybe an inch
or so high that one can place by the garrage doors to divert the water to
the side before it has a chance of entering the garrage ? Does anyone
mfg such an item ? What's it called ? And, how would one fasten the
strip to the asphalt ?
RTV the whole bottom of it, or... ?

Sounds like the pitch of the depression that contains the drain is not
shaped right. I would figure out how to reshape the asphalt to make the
drain work for all rain/flood conditions. A berm or rubber strip would tend
to trip people, and would be a poor substitute for fixing the drainage, or
the location of the drain.
