Strategy
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
Vulnerability Assessment Summary Findings
Gray, Green & Blue Infrastructure
The 100-Year Event and the Category 3 Hurricane expose the most assets within the Palm River redevelopment area. The flooding caused by SLR is isolated to areas along East Bay which does not expose many assets. Combining SLR and surge protection was not performed for this assessment but is recommended to be completed to better understand future threats. The southeast area of the Palm River redevelopment area was determined be the most exposed area within this project boundary due to the number of assets and the frequency they were found to be exposed to flooding. There are eight pump stations and two schools in this area that were all determined to be exposed during the Category 3 Hurricane. Potential improvements for addressing flooding within the Palm River Redevelopment Area include a combination of gray, green, and blue infrastructure such as integrating living shorelines, 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 20 .
• Development of adaptation action areas • Identification of resilience overlay zones • Resilience Comprehensive Plan Chapter – Peril of Flood • Dual 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
