Predominant Soil Types

Margate fine sandBoca fine sandOkeelanta muckPaola fine sand

Eastern Palm Beach County features poorly drained sandy soils with high organic content near the coast, while the western Everglades Agricultural Area (EAA) contains deep muck soils (Histosols) that subside when drained. The sandy soils have moderate-to-rapid permeability but are underlain by a shallow limestone aquifer that limits vertical drainage.

May through October delivers approximately 75% of the annual 63 inches, with August and September being the wettest months. Tropical systems can dump 10-15 inches in a single 24-hour period.

Typical West Palm Beach Drainage Solutions

French drain systems with exfiltration trenches for residential properties
Swale-and-berm systems for properties in low-lying eastern communities
Retention and detention ponds for commercial and subdivision developments
Pump-assisted drainage in areas where gravity outfall is limited by canal levels

County Requirements

Palm Beach County Drainage Engineering Notes

Palm Beach County's Fill and Grading Ordinance (PB-O-128) is one of the strictest in Florida — any fill placement that could alter surface water flow patterns requires a permit with engineer-stamped grading plans. This regulation directly impacts residential drainage projects because even minor regrading of yards requires professional engineering documentation.

The western portion of Palm Beach County lies within the Everglades Agricultural Area, where centuries of peat and muck deposits create unique drainage challenges. These organic soils subside at a rate of approximately 1 inch per year when drained, meaning drainage systems must be designed to accommodate ongoing elevation changes over their service life.

Environmental Considerations in West Palm Beach

Lake Worth Lagoon and Loxahatchee River are impaired water bodies requiring enhanced water quality treatment for all stormwater discharge

Projects near the Arthur R. Marshall Loxahatchee National Wildlife Refuge face additional federal review requirements

SFWMD's C-51 basin criteria apply to most eastern county drainage projects

Saltwater intrusion into the Surficial Aquifer is a concern for deep exfiltration trench design

Permit Timeline for West Palm Beach Residential building permits: 2-4 weeks. SFWMD General Permits: 30-60 days. SFWMD Individual ERPs: 90-180 days.
