The Girl Scouts are selling Miami-Dade County land to expand Matheson Hammock Park, which will provide a 10-foot-wide nature trail and pedestrian access to the west side of the park, expanding nature-based programming. Up for purchase is a vacant half acre at 9950 Old Cutler Road. The proposed contract is for $415,000 for land that was appraised in February 2016 at $440,000. Added to the county’s cost would be $6,500 for closing the sale. The park, at 9610 Old Cutler Road, is now 462 acres.
