Riverside was Miami's first subdivision west of the Miami River. The area came to be called “Riverside” for its location next to the Miami River. Mary Brickell platted the Riverside subdivision. The most important developers of the areas were the Tatum brothers, creators of the Lawrence Estate Land Company subdivision which represented a large segment of Riverside. They came to Miami from Dawson, Georgia in the late 1890s. The Tatum brothers’ advertisements characterized the area as “The Beautiful Ridge” owing to its verdant, elevated terrain close to the river. In an advertisement appearing in 1906, J.H. Tatum and company exhorted Miamians to “buy a lot in Riverside”, especially since “the electric trolley line will be completed through (Riverside) in 90 days and the price of all lots will be increased 50%”. The Tatum’s sold lots in Riverside, in 1904 for $300 to $350. The area during its early history contained many elegant two story frame homes. As the second and third decade of the 20th century unfolded, many of the newer homes were bungalows.
