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.

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 92.46% (often still reflecting the prior assessment base).

Flood zone for 105 W DEWEY AVE

FEMA’s flood map did not respond for 105 W DEWEY AVE. 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 645.6 feet and the highest at 789.5 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.

This lot is within the Wharton WD water system. Please verify with the provider.

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.

Assessed value & ratio history

Parcel assessed nets come from MOD-IV year files (2023, 2024, 2025, 2026). Town average ratios are from Abstract / Chapter 123 when available — implied equalized = assessed ÷ (ratio ÷ 100).

Tax year Assessed net Avg ratio Implied equalized Assessed Δ Equalized Δ
2023 $16,700,000 89.75% $18,607,242 — —

2026 $21,000,000 100.00% $21,000,000 +10.5% -1.4%

2024: Published average ratio exceeded 100%; New Jersey treats that as 100% for equalization.

2026: 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 92.46% (often still reflecting the prior assessment base).
