Martin County was created in 1925 with the northern portion coming from St. Lucie County and southern portion coming from Palm Beach County. It was named for John W. Martin, Governor of Florida from 1925 to 1929.
When the county was created, the western contour followed the shore of Lake Okeechobee, as did the borders of Glades, Okeechobee, and Hendry counties. Palm Beach County had historically claimed all of the surface of the lake as part of its area, to its benefit for the distribution of state and federal highway funds. The state representative of Martin County, William Ralph Scott of Stuart, initiated a bill to divide the lake among its adjacent counties, creating a more equitable distribution of state funds for road creation and maintenance. All bordering counties confirmed the justice of this change and supported its ratification, with the exception of Palm Beach County. Representatives from Palm Beach County later presented Representative William Scott with a jug of water, signifying "all the water Bill Scott left Palm Beach County." The jug is in the possession of Stuart Heritage.

According to the U.S. Army Corps of Engineers, the Martin County Shore Protection Project includes nourishment of approximately 3.75 miles of beach extending from the St. Lucie County line south to the Stuart Public Beach Park in Martin County. Included in the project is restoration of the primary dune and a 35-foot-wide protective berm. The renourishment interval for this project is every 7 years. 
The last renourishment of the Martin County Shore Protection Project was completed in May 2013 and included a Flood Control and Coastal Emergency component due impacts incurred with the passage of Hurricane Sandy in 2012. The next renourishment event is scheduled for 2019. 
The estimated total cost of this project is $69.9 million, $32.5 million of which is to be paid for by the U.S. Federal Government. In Fiscal Year 2015, no funding was appropriated to the project by the U.S. Congress. In the Fiscal Year 2016 U.S. President's Budget Request to the U.S. Congress, no funding dollars was requested for the project.
