COBB COUNTY - A final public hearing on the River Line Master Plan will be conducted Tuesday night, and county commissioners could adopt it then.

The plan addresses land use, preservation and recreation planning for an area in South Cobb bound by the Chattahoochee River and Buckner Road and encompassing eastern portions of Veterans Memorial Highway and southern portions of Oakdale Road.

The purpose is to give the area a definitive character, much like Vinings and Mableton, by creating more neighborhoods and attracting more businesses.

Karen Barton of the Chattahoochee Industrial Business Association said the public meetings started out contentious, but have been more productive since the business community has been included in them.

"No one in the business community was represented on the steering committee, so that was a very big problem for us," Barton said. "But we're working together now, and we support the approval of this plan. I said it two months ago, and I'll say it again - we're not going anywhere."

On the regular agenda, the board will be asked to approve an amendment to the Memorandum of Understanding with the city of Kennesaw for a $6 million increase in cost for the Jiles Road reconstruction project.

The city will pay 40 percent, up to $2.4 million, and the county will pay the remainder. Cobb Department of Transportation Director David Montanye said the original estimates, done in 2004, are outdated.

"After Hurricane Katrina, the cost of asphalt more than doubled," Montanye said. "We also underestimated the right-of-way costs, and didn't scope this project back like we did some others. But we are using the savings we are incurring from other projects to fund it, and this is just a safe estimate, so the full $6 million may not be needed."

Montanye said that the total project should be completed at the end of 2010 and could total $26 million.

The board is also expected to approve the naming of the new Community Development office on Powder Springs Road as the Henley Vansant Wing, in honor of the former county Planning and Zoning Commission chairman.

Vansant worked with the county's zoning for 20 years before his death in July 2006 at age 83.

"Henley was a true gentleman who was a very steady voice as the county witnessed tremendous growth," Chairman Sam Olens said. "In addition to his service to the county, he worked with countless nonprofits and was thoroughly loved by this community. We had thought about other avenues of honoring him, but none of them had the direct correlation that the community development center does."
