What about the sand that will be tracked into the dorms?

It’s a fair question — and perhaps the biggest downside to the Atlantic City Gateway Project that celebrated another milestone last week with the topping-off ceremony for the six-story building that will be the ultramodern, millennial-in-mind workplace of South Jersey Gas, one of the two anchor tenants of the project.

The other is the satellite campus of Stockton University, which will offer classrooms and dorm rooms for college students.

Hence the sand — and the host of other college-age issues that come with dorms.

But to say that’s a negative for the project is to find reason to criticize work whose potential positive impact on the region cannot be overstated.
