Understanding the city’s flood zones is crucial for residents, property owners, and businesses, as it directly impacts safety, insurance, and future development.

Delving into the Flood Zone Map: A Visual Guide to Risk

The St. Petersburg flood zone map, developed and maintained by the Federal Emergency Management Agency (FEMA), serves as a vital tool for understanding flood risk. This map divides the city into various zones based on the likelihood of flooding from different sources, including:

• Coastal Flooding: Rising sea levels and storm surges driven by hurricanes and tropical storms pose significant threats to coastal areas.
• Riverine Flooding: Heavy rainfall or dam failures can cause rivers and streams to overflow, inundating nearby properties.
• Urban Flooding: Poor drainage systems, inadequate infrastructure, and rapid development can lead to localized flooding in urban areas.

Understanding the Zones:

The flood zone map utilizes a standardized system with different designations, each indicating varying levels of flood risk:

• Special Flood Hazard Area (SFHA): This zone encompasses areas with a 1% chance of flooding in any given year, commonly referred to as the "100-year floodplain." Properties within this zone are considered high-risk and require flood insurance for mortgage financing.
• Zone X: Areas outside the SFHA, typically considered low-risk, but still susceptible to flooding.
• Zone AO: Areas subject to inundation from coastal flooding, typically within the 100-year floodplain.
• Zone AE: Areas within the 100-year floodplain, subject to inundation from riverine flooding.
• Zone AH: Areas within the 100-year floodplain, subject to inundation from both coastal and riverine flooding.
• Zone A: Areas within the 100-year floodplain, with the specific flood hazard not yet determined.
