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

This bill changes how municipalities calculate impervious surfaces for parks in the Highlands preservation area. It specifies that all municipal parks within a single town should be treated as one property (not individually) when measuring impervious surface percentage against the 3% limit. The calculation excludes Highlands open waters and solar panels from the impervious surface count. This directly affects municipal park development projects in the Highlands region, making compliance with the 3% limit easier by allowing combined park area calculations.
