Great photo! Good to see this attempt being made.
It was spec'ed to be a White Pine; which it clearly is not.
Appears to be in the range of 35ft tall, a bit less that spec'ed but a very good size.
I believe so, yes.
Keep in mind, I don't have the change order; and I'm looking at a bald, needle-less tree.
The only other one that looks vaguely similar is Bald Cyprus tree.
The base doesn't look right to me for that, so I lean Dawn Redwood.
The easy way to tell the difference is whether the needles are opposite or alternate..........but that doesn't work when they're bald!

Personally, I question that choice; likely more resilient than White Pine would have been; but I'm inclined to think a Swamp Hardwood such as Silver Maple or Swamp White Oak might have been a safer choice (and better looking in winter).
But I digress, I hope it does really well.
Both species needles turn red to burnt orange in the fall, before dropping just like deciduous trees.
Both have only limited tolerance for salt.....but can handle some spray.
