San Francisco's tightly packed 43 square miles makes curbside parking tough. As in all big cities, th downtown is heavily striped and metered. Parking garages are expensive, and double-parking is widespread.
Now, one city official is proposing a way to jar loose more residential spaces. Supervisor Carol Ruth Silver wants to eliminate prohibitive zones.
''I have surveyed my own block,'' Supervisor Silver said, ''-- with a tape measure, too -- and found enough extra off-limits space for five more parking spaces.'' She is encouraging all San Francisco residents to do the same thing and report their findings to City Hall.
