A post office called Palmetto has been in operation since 1868. Samuel Sparks Lamb is considered the "Father of Palmetto," having surveyed and plotted the city at its outset and donated several plots of land. He owned a general merchandise store in town. Samuel Sparks Lamb was from
Clarke County, Mississippi, and arrived in the area near the
Manatee River in 1868 establishing Palmetto. The city received its name from the
palmetto trees near the original town site. Palmetto was first incorporated in May 1893 as a village, with its first mayor being P.S. Harlee. Palmetto was reincorporated as a city in 1897 and in the following years grew. In 1902 with the arrival of the railroad, the center of town moved from the waterfront to the
Seaboard Air Line train station, served by the
Sarasota Branch from
Turkey Creek near
Plant City through Palmetto to "
Bradentown" and Sarasota. By 1921, the
Atlantic Coast Line Railroad was operating a
Tampa Southern Railroad Branch from Tampa to Palmetto and "Bradentown". Compiled during the late 1930s and first published in 1939, the
Federal Writers' Project's
Florida guide listed Palmetto's population as 3,043 and described it as:{{Blockquote A
dolomite mine existed in Palmetto on the
Manatee River from the 1950s to 1974. Several failed attempts were made to redevelop the property. In 1974, the property was almost sold for residential development, but the company backed out due to the
economic recession that was occurring. In 1978, a proposal was made to create a residential community on the site. The site's master plan contained a nationwide motel chain with a restaurant, high-rise apartments along the Manatee River, single-family houses, and a shopping center built around a lake created from mining activities. The former dolomite mine site was bought by WC Riveria Partners. It was then redeveloped in 1998 as Riveria Dunes, a residential community with a marina, townhouses, and homes. ==Geography==
