Gwinnett County commissioners agreed to pay $10 million Tuesday for a Sugar Hill Park.

The county will purchase the 53-acre E.E. Robinson Park, which has baseball and softball fields, tennis and volleyball courts, an amphitheatre, a covered playground, a pavilion and a building for concessions. The sale is expected to close next month.

“Both sides come out winners,” Gwinnett commission chairman Charlotte Nash said. The county is able to expand its parks inventory in an under-served area of the county, while Sugar Hill is able to spend the money it was using to maintain the park in other ways.

Brandon Hembree, a Sugar Hill city councilman, said he did not yet know how the city would spend the extra money. But Gwinnett does a good job managing its parks, he said, and selling it seems like a good partnership. The deal has been in the works for more than a year, Hembree said.

The new Level Creek Park is down the road, and Sugar Hill councilman Curtis Northrup said the two would be the home of the growing Lanier Youth Athletic Association.
