Display Field: zone

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This dataset delineates designated evacuation zones within Hillsborough County, modified to exclude the bay as a waterbody. Each zone is uniquely vulnerable to distinct degrees of flooding induced by storm surges, which are caused by ocean waters being propelled toward the shore by the winds encircling a storm. Hurricanes are systematically classified on a scale from 1 to 5, reflecting their wind intensity and potential destructiveness. The criteria for mandating evacuations in specific zones primarily consider the likelihood of storm surge impacts but also encompass other critical public safety considerations, such as access to emergency services, risk of isolation, and exposure to flooding hazards. Furthermore, each zone is assigned a numeric code that reflects the expected severity of storm surge impact it may face, with zones at evacuation level 1 being vulnerable to surges spanning levels 1 through 5. It is essential to note that these evacuation zones are distinct from flood insurance risk zones, which are established by FEMA and illustrated on Flood Insurance Rate Maps (FIRMs). This delineation ensures clarity in emergency planning and response strategies.**Updated March 2024**
