Johns Creek officials are working to bulk up the city’s park system.

The city council Monday night approved plans for purchase of an approximately 20-acre tract adjacent to Medlock Bridge Road and stretching from Johns Creek Parkway to East Johns Crossing.

The city said the purchase price is just short of $140,000 per acre.

A city spokesman said the land buy would increase total city parkland to 360 acres and would provide recreational space in the north central park of the city, which is identified as underserved in the Recreation and Park Strategic Plan.

A final site plan and development timetable hasn’t been sketched out.
