Option 1
Go by the water dept or local municipal water supply and get a meter 1/2 union with threads on the outlet. Install short brass nipple and threaded ball valve. Cut the old mess out with the curb stop turned off and thread on the new with the ball valve open. Rebuild down stream as you wish.
Option 2
You have threads to the left of that 90 just below the failed ball valve. See option 1 and don't worry about the 1/2 union.
Before I attempted either of these, I'd make sure of three things.
1. I know how much water is still gonna come through that pipe.
2. All the downstream fixtures have been drained, and toilets flushed.
3. The nearest floor drain is not stopped up!
Option 3
This is the one I like the best. Dig up that defective curb stop and replace it. Then replace all those stupid gate valves with good quality ball valves.
This last option is in the best interests of your client. Anything less than this and they're just asking for a problem down the road. With my luck, it would be sooner than later.

Flanged gate valves provide robust bidirectional isolation for critical piping systems across countless industrial applications. However, not all gate valves are created equal when it comes to performance, safety and longevity. There are several crucial factors to evaluate upfront before specifying and purchasing these valves.
From understanding how does a flanged gate valve work? to determining the optimal materials and design configurations, making informed decisions upfront ensures your valve meets operating demands. Overlooking details can lead to premature failures, safety risks and unplanned maintenance down the line.
Key Considerations Before Purchasing Flanged Gate ValvesHere are some of the most important considerations to work through with your flanged gate valve manufacturer and representatives:
