8 City limit 5% of the City is flooded by a 2 ft rise in sea level. Atlantic Ocean

9 City limit 25% of the City is flooded by a 4 ft rise in sea level. Atlantic Ocean

10 City limit 50% of the City is flooded by a 6 ft rise in sea level. Atlantic Ocean

11 The City of Satellite Beach Sea Level Rise Subcommittee and thereafter the Comprehensive Planning Advisory Board recommended the City Council make changes to their Comprehensive Plan in 2010.

12 Example of changes proposed to the City s Comprehensive Plan in 2010 Future Land Use Policy The City shall continue to monitor zoning regulations pertaining to land east of the Coastal Construction Control Line (CCCL) and enact regulations to achieve a balance of among economic feasibility, potential adverse environmental conditions, and limitation of development in the Coastal High Hazard Area (CHHA) sustainability consistent with the character of the City. Policy 1.2.9a - Post-disaster redevelopment shall be governed by all applicable codes, city charter provisions and standards, in regards to setbacks, off-street parking, and landscaping; and shall decrease future public and private vulnerability to future storms by complying with applicable state and county construction regulations and sea level rise.

13 ?! In March 2013, after nearly three years of debate and revision, the City Council approved amendments to the Coastal Element of their Comprehensive Plan. The focal point of these changes was the establishment of Adaptation Action Areas (AAA) and SLR policies.

14 The Coastal Element of the City s Comp Plan now includes an Adaptation Action Area (AAA) policy designed to: Reduce exposure of human life and property to natural hazards while reducing the cost of flood insurance Permit (re)development only when it shall protect life and property from the effects of coastal erosion, flooding, sea level rise, and damage to environmental systems

15 What s happened since adoption of a AAA policy in 2013? In 2014, FDEP awarded a Coastal Partnership Community Resiliency Grant to the East Central Florida Regional Planning Council that was completed in Project goals included: Identify vulnerable lands that could be included in a AAA Engage the public to help set priorities to increase natural hazard resilience

16 DEP Coastal Partnership Community Resiliency Grant Goal: Identify vulnerable lands that could be included in a AAA (in progress) Coastal Erosion (FDEP) Storm Surge (NOAA) Flooding (FEMA) Sea Level Rise (in-house) Source: ECFRPC

17 DEP Coastal Partnership Community Resiliency Grant Goal: Engage the public to help set priorities increase resilience (completed) Based upon stakeholder input during public events, workshops, and ultimately an on-line survey (Metroquest), resident priorities included (higher to lower priority): 1. Loss of Power/Utilities during storms 2. Coastal Erosion 3. Storm Surge 4. Flooding 5. Sea Level Rise 6. Do Nothing

18 Other Actions 1. Established a Sustainability Board..to create more sustainable, environmentally-friendly neighborhoods by reducing consumption and waste, protecting our environmental assets and accommodating hazards associated with our vulnerable coastal location. (2015) 2. Completed an initial sustainability assessment report to create a starting point or benchmark to measure long term performance of city sustainability initiatives. (2015) 3. Refining select infrastructure maps and metadata (2016) Delineating building footprints and first floor elevations to facilitate more accurate flood damage assessments Updating stormwater conveyance data to facilitate planning and capital improvements to vulnerable infrastructure

19 In summary: Over the past 8 years, here has been significant progress since completion of the City s initial vulnerability assessment that began in Comprehensive Plan has been amended to include AAA policies Community education and outreach is helping identify and prioritize adaptation options Work currently underway to identify AAAs and refine the City s infrastructure database Created a Sustainability Board and completed baseline assessment All of these actions are designed to optimize resilience to natural hazards (i.e., erosion, flooding, SLR) under conditions of a changing climate. The final challenge will be to successfully complete and implement an adaptation action plan.
