Every street is a section first: a cut through asphalt, soil, pipes, roots, and the ambitions of four decades of planners.
Draw the section and the arguments resolve themselves. A twelve-metre carriageway is a political statement; a two-metre pavement is another. The drawing does not lie about who the street belongs to.
The best studios keep their sections honest — one line for the kerb, one for the tree, and a scale bar that everyone can read.
