Garza developed a new method of reinforced concrete construction that had been utilized in his landscape designs for Chapultepec Forest in Mexico City. Prior to his exile "for political troubles" he conducted experiments with the Garza System at the Colonia de "El Imparcial" outside of Mexico City [now Colonia Clavería], that were witnessed by other architects and engineers and later published -- along with a New Orleans residence he designed -- in Building Review (New Orleans, June 1922). He patented his system in the United States on 2 August 1921.
Less than a month after applying for LAA membership, Garza died. He was buried in St. Louis Cemetery No. 3.
