Nobody answers
What Nobody Confirms
Two questions, asked properly and repeatedly, closed. This page exists because a desk that hides its failures cannot be believed about its successes.

The two
Whether a roof stays free. No lot will commit covered ground in advance. The replies are versions of subject to availability, which is a reasonable position for a lot and a closed door for a reader.
Whether anyone is there at night. No lot will state a staffing level in writing, because a written staffing level becomes a duty on the night somebody is ill.
What would have to change
For either to open, an operator would have to agree in writing to a service level for holds placed through a third party, and then keep it. That is a commercial arrangement this counter does not have and is not close to having, and any site claiming otherwise about the same city is describing something worth checking.
If one ever does, the line moves from the empty square to the filled one, the date changes, and corrections records the move. Until then the squares stay empty.
Why not simply remove them
Three reasons, in order of weight.
Because the questions do not go away. A reader who is not told will ask at a gate at five in the morning, which is the worst possible moment and the one where an addition is most likely.
Because the six answerable lines depend on it. A worksheet where everything is answered is a feature list. The empty squares are what make the filled ones evidence rather than marketing.
Because it sets the honest ceiling. No parking desk in this city can promise a roof or a night watch. A site that implies either is describing a service nobody sells, and a reader comparing sites deserves to know where the real ceiling is.
The words that follow from this
Because these two are closed, this site uses no word from the safety family about any ground, anywhere, in any form, including in a caption or a heading. The trade's required phrase appears once, as a lot's own quotation about its own boundary, on the perimeter line.
Eight of the nine flags on the claims sheet are marked not stated for the same underlying reason: no agreement with any operator exists, so nothing about an operator's ground, staff or terms can be promised from here.
What you can still decide on
The six answerable lines, and they are enough for a real decision: what a lot says about its boundary, what pattern its shuttle runs, what happens after a clearance run, what an extra day costs, what the quote contains, and when each question stops being answerable.
