This created a desperate need for black housing in the city, so home builders worked with the Dallas Negro Chamber of Commerce (today the Dallas Black Chamber of Commerce) to stir up activism to get developments built.
[3] The largest proposal was a 3,000 acres (12 km2) community along the Trinity River, 5.5 miles (8.9 km) northwest of downtown that blacks ultimately rejected due to its proximity to the "riverbottom."
In 1953, the group donated US$216,872.93 to the Dallas Citizens' Interracial Association to purchase a 233 acres (0.94 km2) site for Hamilton Park.
It contained a shopping center, a park, a twelve-grade school (later made six-grade), 742 single-family homes and an apartment complex.
[3] Hamilton Park's prime location is at the SE portion of what is now the High Five Interchange or the intersection of North Central Expressway (US 75) and I-635 attracted interested in 1985 — that year, a developer proposed to purchase part or all of Hamilton Park for high-rise buildings but residents opposed the proposal and it fell through.
