The "Liberty State Park Protection Act"; establishes Liberty State Park Advisory Committee and requirements concerning DEP actions related to Liberty State Park.

The protected interior area of Liberty State Park was reduced from 235 acres to 215 acres. Of that 215 acres, only 165 acres are designated for natural restoration with science-based flood resiliency habitats, while 50 acres are now allocated for active recreation sports facilities per the DEP's 2025 Master Plan.

A new legislative finding (subsection i) was added describing the August 2025 DEP Master Plan for Liberty State Park, noting it resulted from over five years of public engagement and is compatible with the public consensus for a Central Park-type park.

The list of approved small-scale commercial activities no longer includes 'uses identified in the management plan,' removing that open-ended category since the management plan requirement was eliminated.

The requirement for DEP to finalize a management plan for Liberty State Park within five years of enactment was deleted entirely. This is because DEP has already issued its 2025 Master Plan, which the bill now references and acknowledges in a new legislative finding.

The requirement for DEP to develop a map depicting Liberty State Park within one year of enactment was deleted, along with all references to the now-eliminated management plan throughout the bill.

The description of what visitors enjoy at the park was substantially reworded: visitor count increased from five million to six million; 'peacefulness and passive recreational opportunities of green open space' was replaced with 'green, free, urban open space for varied passive and unstructured active recreational opportunities, in addition to the dozens of acres of structured active recreation facilities'; and 'family picnic areas' became 'playgrounds, picnic areas.'

The advisory committee seat previously held by the chair of the Jersey City Environmental Commission was replaced with the head of Jersey City Together (a community organization), shifting representation from a government body to a civic group.
