Casalotti Sector A is a dense block of ridges with Mazzalupo, Tenuta di Porcareccina and Cas. Pantanelle named, and a yellow road crossing it from the west.
The northern edge adjoins Ottavia and La Storta, with Suburbio X Trionfale at the top right. A pink line follows the boundary with Castel di Guido, and a note at the right indicates that Sector B continues.
