One element of contention not related to the restaurant concession is the inclusion of a single line of street trees, spaced apart, along the north side of the plaza. The inclusion of trees was made possible without reducing the usable gathering space of the plaza by the simultaneous decision to remove a painted median strip, that had separated eastbound and westbound traffic along 17th Street, thus increasing the northern limits of the plaza by several feet. The "temporary" metal rails, welded together to make a continuous fence along the north side of the site, were removed as part of the renovation of the plaza. A double line of trees along 17th Street had been planted years earlier as a monument to victims of the Armenian Genocide.
