[I've never dealt with sod before]

The city just sodded the strip between our front sidewalk and the curb
and the part of our front lawn that they destroyed while working on our
street.

They're coming by twice a day to water the sod, but I suppose they'll
stop doing that in a while.

Once the city stops, how often and for how long should I be watering?

It appears that the strip between the sidewalk and curb was too narrow
for the roller that they used on the rest of the sod.

OK to walk on it, or terrible mistake to do so?

Anything I can or must do to have a chance of this stuff taking?
