Hello: Have a slow leak inbetween my house shut-off and street shut-off

figure out how to shut the street main off.

IMHO you are taking a great big risk. Bad things happen when the
connection at the curb stop breaks off as you are wrenching on it.

Call the city/utility and explain why you need a shutoff order.
