Table 15. Adaptation Strategies
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 • Development of adaptation action areas • Identification of resilience overlay zones • Resilience Comprehensive Plan Chapter – Peril of Flood • Dual use transportation systems
Vulnerability Assessment Findings
Gray, Green & Blue Infrastructure
The 100-Year Event and the FEMA Flood are the only scenarios out of the four assessed threats evaluated which expose assets within the 56th Street Redevelopment Area. The 100-Year Event exposes several roads throughout the area, whereas the FEMA Flood exposes a few roads within one concentrated area near Hanna Avenue and 56th Street. Overall, the assets in this redevelopment area have a low risk of exposure. It was determined that the area near the intersection of Hanna Avenue and 56th Street is considered the most exposed within the study area. Potential improvements for addressing flooding within the 56th Street 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 15 .
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
