To all: a bit more on this topic while it's brought up...

Additions, renovations, sewer lines, and other projects can definitely throw a wrench into your garden machine.

It's best to have a bail-out plan in place for the plants, to determinte what could/couldn't/should/shouldn't be saved or moved. Determine how you would move things around in emergency fashion. Consider what's possible: direct transplant or temporarily store? Save any pots over the years you think might help with this. Burlap and large trash bags can also help if tied around root balls. Newspaper linings can help with water retention. Once again, have shady locations ready, as sun will dry dug-up plants in one or two days. If transplanting, get balls of clay off the roots, and water the exposed root ball thoroughly, as you'll notice some rootballs are already somewhat dry in-ground from drought. Add 4-5" of water to the new hole before you start back filling. Add water again halfway through the back fill. Then once full, tamp the soil further in with your feet (EVENLY - too much pressure on one side and the plant will tilt) and then level it again with more soil and repeat. Water just a bit one more time, and mulch it all over. This should be enough water to keep the tree or shrub going for up to a few weeks without much further watering, even in the heat.

Regarding sewer lines, it's EXTREMELY important (especially for new or recently new homeowners) to have yours mapped out and camera'd completely so you know what condition it's in and exactly where it runs. You can lose an entire back yard if your line has to be dug up and replaced. Just having back-hoes, trucks, and excavators can flatten everything in your yard within an hour or two. Once you know where your line runs, keep deep-rooting trees AWAY from the pipes. Over time roots can destroy or completely block the pipes. Get LINE INSURANCE from your gas company if available - $15 bucks a month on your bill can cover replacement of your sewer line, which usually runs from $2000-$10000. If end up facing bills of this magnitude, a few plants will be the least of your worries.

Lastly, if people need to use any part of your property for municipal work, DEMAND they not do so without a something such as a court order, AND/OR make sure they will furnish the cost to replace anything damaged by equipment. And if anyone happens to wreck on your property, their auto insurance SHOULD pay for landscape replacement costs.
