Robert H.H. Hugman drawings, San Antonio River Walk, San Antonio, Texas, 1938-1939
This record group contains 63 working drawings (1938-1939) showing Hugman's Plans for the Improvement of the San Antonio River (Paseo del Rio), Fourth Street South to Villita Street, San Antonio, Texas.
Hugman began work on the design for the project in 1929 in an effort to save the river from being paved over as a flood prevention plan. Completed in 1941, the project spanned 21 blocks of downtown San Antonio and has served as a model of success in urban planning.
