NJ Hazard Vulnerability Dashboard

What this is

The planning-facing twin of the parcel flood risk dashboard. Same parcel backbone, different question: instead of a single-hazard finance lens, this screens every parcel against current flood, future flood and sea-level rise, and storm surge, and scores vulnerability with a transparent framework —

V = 0.45·E + 0.30·S + 0.25·C

exposure, sensitivity, and consequence-context, each visible in the parcel profile so a planner can see why a score landed where it did.

Why build both

Running the two projects on one parcel core is the point: the same data backbone powering two genuinely different decision products, one for underwriting and one for mitigation prioritisation. The second project consumes the first’s artifacts under a documented contract rather than reimplementing parcel ingest — a third implementation of the same ETL would be the failure mode, not a milestone.

Two commitments constrain the design. Every output is labeled screening for prioritisation, never a determination. And “not screened” — a parcel outside a scenario’s data footprint — is carried as its own state, distinct from “not exposed”, because collapsing the two would quietly turn missing data into good news.

Weights are locked at the framework’s starting values with a mandatory calibration check before publication: if well-documented high-risk municipalities do not rank in the top quartile under flood scenarios, the discrepancy gets written up rather than the weights getting nudged.
