Summary: We show that every topological $k$-graph constructed from a locally compact Hausdorff space $\Omega$ and a family of pairwise commuting local homeomorphisms on $\Omega$ satisfying a uniform boundedness condition on the cardinalities of inverse images may be realized as a semigroup crossed product in the sense of Larsen.
