Modifies method of calculating impervious surface percentage for municipal parks in Highland preservation area.

This bill changes how municipalities calculate impervious surfaces (like paved areas) for public parks within New Jersey's Highlands preservation area. Currently, parks must keep impervious surfaces under 3% of each individual park's area. The bill allows municipalities to combine all their municipal parks into one "lot" for this calculation, meaning the total impervious surface across all parks must stay under 3% of the combined park area. This adjustment makes it easier for towns to develop or maintain multiple parks without violating the 3% limit on each separate park. The change specifically excludes open waters and solar panels from the impervious surface calculation.
