Vulnerability Assessment Findings The 100-Year Event and the FEMA Flood Maps expose the most assets within the North Airport Redevelopment Area. The 100-Year Event is not concentrated to one area of the redevelopment area and therefore impacts assets throughout the area. Category 1 Hurricane extents are outside of the redevelopment boundary, but the Category 3 extents impact the southwest corner of the redevelopment area. The area near the intersection of W Hillsborough Avenue and Benjamin Road is the area of highest exposure in the North Airport Redevelopment Area due to the impacts from 100-Year Event, FEMA Flood Maps and Category 3 Hurricane. There are several County maintained roads and the Benjamin pump station which are exposed within this area. Potential improvements for addressing flooding within the North Airport Redevelopment Area include a combination of gray, green and blue infrastructure such as raising roads and adding storage in local and regional stormwater ponds. Improvement strategies should seek to protect or extend the duration from which assets may be exposed. These adaptation strategies and examples are included in Table 16 . Table 16. Adaptation Strategies Intervention Example
Gray • Hardening or raising of infrastructure • Adding storage/capacity • Diverting flows Green • Living shorelines • Bioswales, upflow filters • Landscaping – green roofs, canopy coverage Blue • Passive water parks
Gray, Green & Blue Infrastructure
• Development of adaptation action areas • Identification of resilience overlay zones • Resilience Comprehensive Plan Chapter – Peril of Flood • Duel use transportation systems
Land-use Planning
• Loss avoidance studies • Benefit-cost analyses (GIS based) • Schema development/updates • Assigning condition codes • Assigning remaining useful life
Disaster Planning
Asset Management
• Update of Stormwater Master Plans (frequency based – e.g. every five years) • Attenuation/treatment credits • Land Development Code updates • Personal preparedness campaigns in highly vulnerable areas • Build-a-bucket event • Project prioritization that addresses projects in highly vulnerable areas with highly vulnerable populations
