Coastal High Hazard Stakeholder Meeting
October 15 @ 6:00 pm - 8:00 pm
Coastal High Hazard Area (CHHA) refers to the parts of St. Petersburg that are defined as below the elevation of the Category 1 storm surge line. This is established by a Sea, Lake, and Overland Surges from Hurricanes (“SLOSH”) computerized storm surge model from the National Weather Service. The model estimates storm surge heights resulting from historical, hypothetical, or predicted hurricanes by considering the atmospheric pressure, size, forward speed, and track data.
The CHHA has existed since 1985. The definition and applicable standards have changed several times – in 2006, 2010 and most recently 2016. The most recent changes have led to a major expansion of the CHHA – it now includes approximately 25 square miles or 41% of the City. The CHHA impacts key employment centers such as parts of the Innovation District, Skyway Marina District, and Gateway area.
The City of St. Petersburg is considering changes to the planning regulations that would allow safe and reasonable increases in residential density within the CHHA, while also leading to a higher standard of construction that is more resilient to storm surge, mitigates for service and infrastructure needs during and immediately following a major storm event, and enables safe re-occupation as quickly as possible following an evacuation. They are looking at the standards that the county and state have in place already, as well as best practices from cities such as Norfolk, Virginia.
This stakeholder meeting is being hosted by the City of St. Petersburg.
