The Sandy Springs City Council has voted to pay $450,000 for the 23rd property acquired to date for the proposed Hammond Drive widening; and directed an engineering consultant to prepare additional visuals of a future Hammond Drive for a public information open house to be held this fall.

The council approved a purchase agreement for a single-family home and its roughly 0.5-acre lot at 660 Hammond Drive. The sellers of the house, which dates to the 1950s, are John M. Bernhardt, Steven Jackson Bernhardt, and Susan Bernhardt Holliday, according to the sales contract.

The council also approved a $47,500 change order to have Gresham Smith and Partners develop enhanced visualizations, such as oblique aerials and a video animation sequence, of the Hammond Drive Corridor Design Project. These will “aid in communicating the proposed design concept to the public,” Public Works Director William H. Martin Jr. said in an agenda memo to the council.

Under its original contract of $237,985 and a previous, $12,000 change order, Gresham Smith was charged with developing standard corridor graphics, such as corridor plans and typical sections, for the open house, Martin said.
