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 26 — Not a willing-buyer, willing-seller sale, for a reason outside the other codes marks it non-usable, or the price is a nominal amount.

This class 2 — residential (four families or less) — net assessment sits above the town class-2 average of $645,896.

This town revalued/reassessed for tax year 2026. New assessments are set near true market value, so we treat the ratio as ~100% for this year. Published Chapter 123 average ratio for appeals/statistics is still 91.13% (often still reflecting the prior assessment base).

Flood zone for 26 WASHINGTON ST

FEMA’s flood map places the mapped point for 26 WASHINGTON ST in zone X.

The state’s 10-foot ground scan puts the lowest cell on this lot at 138.1 feet and the highest at 150.4 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 26 WASHINGTON ST

This lot is within the Stage II sewer system. Please verify with the provider.

This lot is most likely on a well because it is outside the mapped public water service area. Please verify.

These lines come from the state’s sewer service areas and public community water areas, read at a point for this address. That point can fall in the street. Being inside a named area means the lot is inside that mapped system, not that a pipe or a meter is on the house. Being outside means the lot is outside the mapped service area, which is usually a septic system or a private well. It is not a hookup record. Please verify with the provider.
