Alpharetta is seeking public input on proposed development of an 80-acre site at Ga. 400 and Old Milton Parkway, formerly known as Prospect Park. North American Properties, the new owner, has submitted its proposal for "Avalon," calling for retail, office, hotel and residential uses with additional parcels set aside for future sale or development.

Formal public hearings are scheduled for early March before the Planning Commission, but the city wants residents to weigh in at its Open City Hall Website, http://alpharetta.ga.us.
