Local Market

Jacksonville's port and logistics sector, military base complex (Naval Station Mayport, NAS Jacksonville, Blount Island Command), and active suburban residential and commercial growth create diverse civil engineering demand across Duval and surrounding counties.

Climate & Engineering Conditions

Zone 1A; Jacksonville's extensive wetland and floodplain network means SJRWMD ERP coordination is required for most commercial development sites; the St. Johns River floodplain constrains development in large portions of Duval County; Atlantic coastal proximity requires wind and flood zone consideration.
