El Paso County's second poor farm, known as the El Paso Poor Farm, was established here in 1915. John O'Shea, a wealthy farmer and businessman whose farm was nearby, assumed operation of the farm. His wife, Agnes O'Shea, was in charge of the residents. John O'Shea died in 1929, and the couple's daughter, Helen O'Shea Keleher, came from her home in San Antonio to operate the farm with her mother. The farm was scheduled to be closed in 1929, but, with the troubled times of the Depression era, its population grew. Renamed "Rio Vista Farm," the poor farm hosted a variety of public welfare programs beginning in the 1930s. It operated under the Texas Transient Bureau and later the Federal Works Progress Administration. A temporary base for a Civilian Conservation Corps unit in 1936, the farm continued to shelter hundreds of homeless and destitute adults and children. From 1951 to 1964, the farm was used as a reception and processing center for the Bracero Program, which brought Mexican laborers to work in the lower valley of El Paso and other agricultural areas in the U.S. New Federal welfare programs and state law reduced the population of the poor farm to four, and it was closed in 1964. Unlike other Texas county poor farms, Rio Vista followed a familial rather than institutional model, accepting neglected and abandoned children in addition to the adult indigent population. In later life, Helen O'Shea Keleher cited the fifty years she spent with the more than four thousand orphans and neglected children of the Rio Vista Poor Farm as her proudest accomplishment.

The land in this area was once part of a Republic land grant awarded to pioneer William Grigsby. The Dallas Consolidated Electric Street Railway Company bought twenty acres of the property in 1903, and in cooperation with developers Oliver P. Bowser and William H. Lemmon built Oak Lawn Park. Weekend visitors and prospective land buyers paid five cents to ride the streetcar to the park, which offered a variety of recreational activities. The City of Dallas purchased the park with its native trees in 1909.

In 1928, the Dallas Southern Memorial Association (DSMA) began plans for the placement of a statue of Robert E. Lee in the park. Executed by Canadian sculptor A. Phimister Proctor, the bronze statue was unveiled on June 12, 1936, by President Franklin D. Roosevelt. The park's name was changed to Robert E. Lee Park, and two years later, in a cooperative effort by the DSMA, Park and Recreation Board, and the Federal Works Progress Administration, a two-thirds scale replica of Arlington Hall, Robert E. Lee's home in Virginia (now a part of Arlington National Cemetery) was constructed.

Throughout its history, this park has provided a place of recreation and relaxation for Dallas citizens. It remains one of the city's most popular attractions.

In September 1921 the flooding of the San Antonio River reached as high as eight feet in the center of the city. Loss of lives and property damage were high, and prompted city officials to take action to prevent a recurrence. The Olmos Dam was built and a city engineering report recommended filling and paving the river bend. Protests from the City Federation of Women's Clubs and the San Antonio Conservation Society convinced municipal leaders to view the river as an asset to be preserved.

San Antonio architect Robert H.H. Hugman (1902-1980) developed beautification plans for the river area including walks, foot bridges, landscaping, and retail shops. In 1929 Hugman, W.P. Drought, and city leaders helped Congressman Maury Maverick, Mayor C.K. Quin, and Jack White develop support that led to a Federal Works Progress Administration (WPA) grant to fund the project. In 1938, Hugman was hired as the project architect and Edwin P. Arneson as the project engineer. By 1941 the River Walk was completed.

During the 1960s voters approved a bond for improvements including extending the walk to the convention center. A source of pride for San Antonio, the River Walk is one of its most unique attractions.

The land and springs around this site made it a favored camping site for local Indian tribes for centuries before the Spanish discovered it. Raids, drought and conflict led the Spanish to abandon the area in 1756. The Mexican State of Coahuila and Texas granted a colonization contract to Robert Leftwich in 1825. Conflicting contracts were granted to Stephen F. Austin and Sterling C. Robertson. George W. Glasscock, Sr. (1810-1868) purchased the land while speculating for Thomas B. Huling and Company. In 1839 Glasscock received two headrights including this land as part of his share of assets when the company dissolved.

The site had become a popular gathering place for settlers when Sam Houston spoke here in 1859. It became known as "The Fairgrounds." Large annual fairs, reunions and religious revivals drew crowds from surrounding areas. The county's first public hanging took place here in 1886. Williamson County Old Settlers' Association, formed in 1904, used the area for annual gatherings, eventually leasing 33 acres and building reunion structures. Helen Glasscock, the widow of George Glasscock, Jr., sold the site to I.M. Williams in 1912. A devastating flood in 1921 swept away the fairgrounds.

Georgetown citizens requested that the city buy the site from the Williams family and name it San Gabriel Park in 1933. Under the direction of R.E. Ward, the city improved the park in the 1930s and 1940s. A river wall, low water crossing, large building and rest rooms were erected with funding and labor from the Federal Works Progress Administration. Rodeo pens, sports fields and further land acquisitions continue to ensure that the park provides recreation and shelter for area citizens.

In 1885 a two-story frame structure was built on this site and served as the first free public school in Jacksonville. It was destroyed by a tornado in 1890. A three-story brick building was erected here in 1910-12. Known as the East Side School, it served elementary and secondary students at different times until 1939. After decades of use for school purposes, the hillside stood bare until 1940. In that year a sports stadium, known as the Tomato Bowl, was begun by the Federal Works Progress Administration and the Jacksonville Independent School District.
