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.

Flood zone for 757 ST RT 15 S

The flood map could not be checked for 757 ST RT 15 S, 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 929.8 feet and the highest at 982.8 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 757 ST RT 15 S

The water and sewer maps could not be checked for 757 ST RT 15 S, because the address did not place a point on the map.
