The company develops its land for a variety of uses including residential neighborhoods, hotels, apartment communities, leasable commercial space, office buildings and medical facilities among others.

Over time, properties in other parts of the state were sold as the Company began to focus on strategic land holdings in Northwest Florida.

In 2010, Northwest Florida Beaches International Airport (ECP) opened on 4,000 acres of land donated by The St. Joe Company.

In 2014 The St. Joe Company sold more than 380,000 acres – to AgReserves for $562 million, retaining strategic land holdings concentrated in Northwest Florida.

The St. Joe Company’s current total land holdings in Northwest Florida (including areas outside of the Bay-Walton Sector Plan) is about 171,000 acres.

The 50-year Bay-Walton Sector Plan gives legal rights for The St. Joe Company to develop more than 170,000 residential dwelling units, more than 22 million square feet of retail, commercial and industrial space and more than 3,000 hotel rooms on lands it owns within Bay and Walton Counties.

The hotel's location in downtown Panama City, Florida is undergoing a rebuilding process after sustaining significant damage during Hurricane Michael in 2018.

Fish and Wildlife Service to protect sensitive species including the red cockaded woodpecker, flatwoods salamander and gopher tortoise.

In Walton County the St. Joe Company donated the land at 7800 US Hwy 98 in Miramar Beach where Ascension Sacred Heart Hospital Emerald Coast was built, and helped create a STEAM School named “The Magnet Innovation Center” on land and with facilities previously used as the company’s corporate offices at 133 S. Watersound Parkway.

The staunchly segregationist Ball was du Pont's brother-in-law and also affiliated with the Florida Democrat political group known as "The Pork Chop Gang".

[citation needed] The Apalachicola Northern Railroad had extended its network from Chattahoochee to Port St. Joe, Florida, in 1910, hoping to take advantage of increased shipping trade through the Panama Canal.

Du Pont purchased the struggling railroad, and made plans to use the infrastructure to build a paper mill, leading to the foundation of the St. Joe Company.

Du Pont drew up elaborate plans for the development of his mill town as "The Model City of the South", but died before it could be completed.

The company invigorated the local economy following the Depression, employing thousands at its paper mill, but wreaked havoc on the environment.

St Joe Paper also clear-cut millions of acres of old growth forest, engaging in silviculture to replant the areas with slash pine.

[23] After the dismantling of the paper mill, the St. Joe Company was back in town in 2008 to unveil a $344 million plan for the former mill site that was similar to Alfred du Pont's idealized Southern town – an integrated city with upscale residential districts, entertainment venues, a thriving port, and a diverse economy.

St. Joe received negative publicity for their south Florida sugar cane business from labor unions and environmental groups, including by Cesar Chavez of the United Farm Workers.

[29] As a result, the company cut its workforce, exited the homebuilding market and sold its office holdings[30] which included the corporate headquarters built in 2003.

In the late 1900s, St. Joe began to sell timber land in rural areas after deciding to focus on community and commercial development.

[32] On March 18, 2010, the company announced plans to relocate their corporate headquarters to a site near the Northwest Florida Beaches International Airport when their lease expired in 2011.

The company's largest shareholder, Fairholme, disagreed with management's asset development plans and sought to replace certain board members.

[34] In 2013 St. Joe Company sold 382,834 acres to AgReserves in Bay, Calhoun, Franklin, Gadsden, Gulf, Jefferson, Leon, Liberty and Wakulla counties.

The idea of the airport received hostility from some local taxpayers (56% opposed it in a non-binding referendum) that funded the project and environmental groups that sued St. Joe six times.

[37] Residents pointed to the fact that St. Joe already had a 50-year, 100,000-acre development plan based on the airport and quotes such as "Silicon Valley was in the middle of nowhere ...We think we can do the same thing."

[36] St. Joe owns about 78,000 acres (320 km2) of land in the area surrounding the new airport site, and has announced plans to build 5,800 homes and 4,300,000 square feet (400,000 m2) of commercial space.

[33] During construction even light rainfalls created mudslides that washed sediment into the surrounding wetlands with a decline in water quality as a result.

For example, in the year ending June 26, 2012, the airport had 47,604 aircraft operations, average 130 per day: 47% general aviation, 23% military, 16% airline, and 15% air taxi.
