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.

The stored sale is not used for a change-since-sale figure. SR1A 06 — Sale of only part of the assessed parcel marks it non-usable, or the price is a nominal amount.

Flood zone for 20 JOHANNA FARMS RD

The flood map could not be checked for 20 JOHANNA FARMS RD, because the address did not place a point on the map. Assessment and tax figures on this page are from our own records.

The state’s 10-foot ground scan puts the lowest cell on this lot at 147.1 feet and the highest at 201.8 feet (NAVD88).

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. No zone at this point, or zone X, does not mean the lot will not flood.

Water and sewer for 20 JOHANNA FARMS RD
