Engineering and design plans for the Thurmond Tanner Parkway extension are in the final stages of approval.

Stan Brown, Oakwood city manager, said Oakwood City Council approved engineering and environmental details Monday for the road extension which will connect to Mundy Mill Road.

Brown said the Department of Transportation could begin work on the project in September.

The City Council also established sewer rates for city sewer customers on Winder Highway and Martin Road, as well as potential city sewer customers on the planned railroad sewer line system.

Brown said Oakwood will implement an initial sewer rate for those customers that will cover the city’s cost in using Flowery Branch sewer services and for new sewer lines yet to be laid. Brown said the base charge is set for $38.18 for the first 2,500 gallons of sewer service and $11.94 for every additional 1,000 gallons.

The City Council also modified two zoning conditions for Madison Retail and the Royal Lakes neighborhood to allow for a sign at the subdivision entrance and a golf cart path on the property.
