Westside The Westside has grown in recent years as developers search for expansive alternatives to some of the city’s more crowded regions. Because it still contains a lot of untapped potential, the Westside can still be marketed as a community that offers the tranquility of country living. A lot of diverse investment has crept into the Westside in recent years. The largest Westside development since Argyle Forest in the 1970s, that will take years to build out, is OakLeaf Plantation, which has come to life on 6,400 acres of unspoiled land adjacent to the Jennings State Forest, which has 20,000 acres. Straddling parts of both Clay and Duval counties, OakLeaf has caused officials to plan for new public safety services and new schools to meet future growth in this Development of Regional Impact or DRI. Another factor that is sure to contribute to growth in the Westside is the manufacturing sector at the Cecil Commerce Center, the former Cecil Naval Air Station, which is quickly becoming a hub for aerospace companies.
