Planning and zoning commissioners unanimously voted to rezone large chunks of Bayport Park and Lake Townsen Preserve to conservation status.
The recommendation now goes next month to county commissioners, who are the last word on zoning issues.
Planning Commissioner Robert Widmar said the move is more consistent with the zoning already in place.
Unless overruled, the move would place more than 127 acres of Bayport Park from residential-agricultural zoning to conservation.
The conservation designation is consistent with the planned, long-term public use and management objectives for the property, according to planning staffers. It would retain and preserve the land, its resources and wildlife habitats.
The conservation category is also "consistent with the county's zoning definitions, comprehensive plan policies and other environmentally sensitive land properties," a staff report said.
The planning board's actions would also place some 83 acres of Lake Townsen into the conservation category.
Lake Townsen is located north of Lake Lindsey Road and east of Lingle Road.
