We study the Hamiltonian dynamics of a five-dimensional Chern-Simons theoryfor the gauge algebra $C_5$ of Izaurieta, Rodriguez and Salgado, the so-calledS$_H$-expansion of the 5D (anti-)de Sitter algebra (a)ds, based on the cyclicgroup $\mathbb{Z}_4$. The theory consists of a 1-form field containing the(a)ds gravitation variables and 1-form field transforming in the adjointrepresentation of (a)ds. The gravitational part of the action necessarilycontains a term quadratic in the curvature, beyond the Einstein-Hilbert andcosmological terms, for any choice of the two independent coupling constants.The total action is also invariant under a new local symmetry, called "crosseddiffeomorphisms", beyond the usual space-time diffeomorphisms. The number ofphysical degrees of freedom is computed. The theory is shown to be "generic" inthe sense of Ba\~nados, Garay and Henneaux, i.e., the constraint associated tothe time diffeomorphisms is not independent from the other constraints.
