St. Johns County Soil & Drainage Profile
St. Johns County features poorly drained flatwoods Spodosols across most of the mainland with well-drained dune sands along the coast. The county's rapid development is converting large tracts of flatwoods to residential use, requiring comprehensive stormwater engineering for each new subdivision.
June through September delivers approximately 55% of annual rainfall. St. Augustine averages 51 inches. Nor'easters from September through March can produce significant rainfall with coastal flooding.
Typical St. Augustine Drainage Solutions
- Master-planned community stormwater networks for Nocatee and World Golf Village-area developments
- Retention pond systems meeting SJRWMD criteria for new subdivisions
- Historic district-compatible drainage for St. Augustine properties
- Coastal drainage with nor'easter and hurricane surge protection
St. Johns County Drainage Engineering Notes
St. Johns County is Florida's fastest-growing county by percentage, with master-planned communities like Nocatee and Shearwater transforming thousands of acres of pine flatwoods into residential neighborhoods. The engineering challenge is designing stormwater systems that handle the dramatically increased runoff from impervious surfaces while maintaining the character of the natural landscape that attracted residents in the first place.
Historic St. Augustine — the nation's oldest city — presents unique drainage challenges. The narrow streets, historic structures, and sea-level location make conventional stormwater management impractical. Drainage solutions must be compatible with historic preservation requirements while still providing effective flood protection for properties that are centuries old.
