(Richmond, IN)--The plan to add residential housing to a 19-acre area just south of Walmart in Richmond took a major step forward Monday night.  Richmond Common Council, by a 5-2 vote, approved rezoning for the area that is bordered by South 37^th to the east and Backmeyer Road to the south.  Several council members had expressed concern over traffic impacts – particularly on Backmeyer.  The developer’s commitment to fund a traffic study played a role in Monday night’s passage.
