His administration also sold the original Teatro Colón to the Banco de la Nación Argentina, proposed construction of a new lyric theater at the current Congressional Palace site, surrounded by a grand plaza with four diagonal avenues, and prioritized wider avenues and new green spaces as public health measures to combat frequent epidemics. His contributions to Buenos Aires were later commemorated through the naming of Villa Crespo, a neighborhood that honors his legacy.
