How the ratio works: New Jersey towns often assess below full market value. The average ratio (Director’s / Chapter 123) estimates what percent of true market value the town’s assessments represent. Implied equalized value ≈ assessed net ÷ (ratio ÷ 100). Example: assessed $187,600 at 55.89% ≈ $335,700 equalized. Tax bills still use assessed value × the general tax rate — not the equalized figure.

These figures are estimates. The zone and any flood elevation come from FEMA’s flood map at a point for this address, and that point can fall in the street. The high and low come from the state’s 10-foot ground scan of the lot outline. A cell can catch a ditch, the street, or the edge of the lot. They are not a survey and not an insurance rating. A licensed surveyor measures the ground and the building. The town floodplain administrator, or a licensed engineer, confirms what the zone means for this lot.
