Dollar damages are aggregated to the County Boundary from the census block level outputs. USACE SUM_FC_DL_EAD Future Conditions Depreciated Losses Expected Annual Damages Double 8 38 8 Future Condition (with sea level rise) expected annual damages are damages expressed as a monetary value that occur in any given year if all AEP event probabilities and magnitudes were spread out equally over time. Dollar damages are aggregated to the County Boundary from the census block level outputs. USACE Sand_Balance_50yr Sand Balance 50 yr (cy) Double 8 38 8 The 50-year sand balance in cubic yards in the county. The sand balance calculation is: Sand Balance = Sand Need – (Proven/Potential Offshore area volume + 50 yr RSM volume). USACE PercentSandNeedAvailable Percent of Sand Need Available Double 8 38 8 The Percentage of Sand Need Available is the ratio of sand available (offshore sand sources and RSM sources) to the sand needs for each county. If this percentage is greater than 100%, it indicates a sand surplus; if less than 100%, a sand deficit is identified.

USACE Tier1_EC_MedHigh_Risk_Places Tier 1 Existing Conditions Medium to High Risk Places Double 8 38 8 The number of Medium to High Risk census places within the county for existing conditions identified in the SACS Tier 1 Risk Assessment. Medium and high potential risk was used as a cutoff for High Risk Places as depicted in the SACS Main Report. USACE Tier1_FC_MedHigh_Risk_Places Tier 1 Future Conditions Medium to High Risk Places Double 8 38 8 The number of Medium to High Risk census places within the county for future conditions (with sea level rise) identified in the SACS Tier 1 Risk Assessment. Medium and high potential risk was used as a cutoff for High Risk Places as depicted in the SACS Main Report. USACE Tier2_EC_MedHigh_Risk_Places Tier 2 Existing Conditions Medium to High Risk Places Double 8 38 8 The number of Medium to High Risk census places within the county for existing conditions identified in the SACS Tier 2 Economic Risk Assessment. USACE Tier2_FC_MedHigh_Risk_Places Tier 2 Future Conditions Medium to High Risk Places Double 8 38 8 The number of Medium to High Risk census places within the county for future conditions (with sea level rise) identified in the SACS Tier 2 Economic Risk Assessment. USACE ProvenPotentialBorrowAreas Proven and Potential Offshore Borrow Areas Estimated Volume (cy) with Confidence Factor Double 8 38 8 Total estimated offshore borrow area volume with confidence factor for proven and potential offshore borrow areas for the County. Proven areas are defined as resource areas with beach-quality sand whose thickness and lateral extent have been fully determined through design-level geotechnical data and in most cases are permitted. Potential areas are defined as resource areas with beach-quality sand whose existence has been verified through preliminary geotechnical and geophysical data (with vibracores approximately one mile apart). Thickness and/or lateral extent has been preliminarily determined. USACE Estimated50yrRSM Estimated 50-yr RSM Volume (cy) Double 8 38 8 The estimated volume in cubic yards available for the County from Regional Sediment Management beneficial use dredging opportunities for 50 years. USACE SandNeed_50yrContingency 50-yr Sand Need Volume (CY) with +55% Contingency Double 8 38 8 The estimated volume in cubic yards of sand needs for 50 years for the entire county with a 55% contingency. The 55% contingency is comprised of three components 1. 10% - 30% dredge inefficiency (sand left in the borrow area) 2. 5% - 15% placement losses (dig-to-place losses) 3. 10% - 25% future project performance, including sea level rise impacts. While the sediment needs calculations incorporates past events, the 50-year needs calculation does not forecast either erosion or damage from a given future storm or the effects of sea level rise.
