i dont see how a strainer will particularly help your situation. seems to
me it will just catch more twigs and leaves and clog faster.

seems better to divert the water someplace else completely if possible.

I have a 3" drain on my driveway next to the house which takes rainwater
and
puts it back into the city's sewer system. During stormy weather the drain
has a tendency to slow down or stop because of bits of twigs, leaves and
other debris start to accumulate around it. If this happens it's possible
that my garage floor gets flooded because a small lake starts to form
around
the drain. I've heard of laundry sink strainers can help. Do they make
this
in a 3" size? How else could I fix this problem?
