Special Overlay Zones

Tampa Bay / Boca Ciega Bay Coastal Zone
Trigger: Properties draining to Tampa Bay or Boca Ciega Bay (virtually entire city)
Restriction: Enhanced water quality treatment to support Tampa Bay estuary; nutrient reduction BMPs; Boca Ciega Bay is an Aquatic Preserve with stricter protections
Flood Zone / Coastal High Hazard Area
Trigger: Properties in FEMA VE, AE, or coastal high hazard zones (significant portion of city)
Restriction: Elevated construction; coastal setback requirements; no fill in floodway; sea level rise considerations in stormwater design

Design Manual

Manual Name
SWFWMD ERP Applicant's Handbook Volume II / City of St. Petersburg Engineering Design Standards

Jurisdiction Notes

St. Petersburg occupies a peninsula between Tampa Bay and Boca Ciega Bay, meaning virtually all stormwater eventually reaches estuarine waters. The city's flat terrain and high water table make wet detention the dominant BMP approach. Sea level rise is an increasing factor in stormwater system design.

Remember: These local requirements are in addition to the FDEP state construction permit. Both must be satisfied before breaking ground.
