Revises notice requirements for certain local land use hearings to at least 21 days.

S 3657 requires at least 21 days' notice for certain local land use hearings in New Jersey, increasing the current 10-day requirement. It affects municipalities holding hearings on land use ordinances (like street changes or property assessments) and property owners whose land may be impacted by these decisions. The bill mandates that written notice be mailed to affected property owners at least 21 days before the hearing, instead of the previous 10-day period. This change applies to hearings on development applications, street improvements, and other land use matters that require public notice.
