This photo is an aerial photograph shows the Ripley Arnold project.  Clarkson was the Chief Architect with five associate architects: Whithers, Geren, Pelich, Crane, and Hedrick.  The Fort Worth Chamber of Commerce has this information about the project:

"Fort Worth’s first public housing development, completed in 1940, was named to honor Major Ripley Arnold, commanding officer of the Fort on the Bluff overlooking the Trinity River that became Fort Worth (1849).  Six local architects designed the apartments in 1938 to provide affordable housing for low-income white tenants. Butler Place, several blocks east, was built at the same time for African-American residents. Funding for the 252 modernistic brick and concrete dwellings came from the United States Housing Authority and the sale of City of Fort Worth Housing Authority bonds. Twenty-eight new homes were added in 1962. Units were racially integrated in the 1960s and air conditioning was added in 1996. Ripley Arnold Place was sold in 2001; its proceeds provided seed money for mixed income developments in neighborhoods throughout the city. This new housing created better environments for residents and their families."

The Ripley Arnold Housing project has now been demolished.  The Butler Place Project is still in use and was listed on the National Register of Historic Places in 2011.

From the National Register:

“The Butler Place Public Housing Project was one of fifty-two Public Works Administration low-income housing projects built in the United States. The complex is significant for the manner in which its architectural design and site organization expressed the social ideals and planning standards of the period, in compliance with strict federal Public Housing Administration guidelines…

Modernist design principles stressed form and function, rejected superfluous ornamentation, and incorporated a philosophy of social change. Consequently, these principles were employed in some of the first federally funded public housing projects such as the Carl Mackley Houses in Philadelphia in 1935, and Cedar Springs Place in Dallas, which was constructed in 1937. Wiley G. Clarkson and associate architects also applied these modernist ideals at the Butler Place and Ripley Arnold housing projects in Fort Worth in1939. Their organization to provide an open atmosphere of light and air also found inspiration in the Garden City Movement. According to Judith Johnson’s The Art of Architecture: Modernism in Memphis 1890–1980, these design principles were based upon the theory that a housing project is not merely a collection of dwelling units, but that it provides the basis for a way of life for its inhabitants within the planned framework of a neighborhood…

At Butler Place, the brick veneer buildings were designed in a stripped or minimalist adaptation of the Colonial Revival style, which was popular for domestic architecture in the United States in the early twentieth century.”
