The Summit County Commission, in a split 2-1 vote, gave the discount retailer the green light to expand its 72,000-square-foot operation to 115,000 square feet.

The bigger store will include grocery.

The Snyderville Basin Planning Commission had previously approved the conditional-use permit for the expansion with the caveat that increased traffic from the enlarged store could be mitigated.

The realignment and expansion of Landmark Drive that is nearing completion at Kimball Junction will meet that condition, said Commissioner Bob Richer.

"The road project mitigates and improves traffic flow for all businesses in the area." Among other things, Wal-Mart paid a $145,000 traffic-impact fee.

Commissioner Sally Elliot cast the lone dissenting vote because she said the planned 74-square-foot sign for the building would be too big.

Smaller businesses in the area are restricted to signs no larger than 30 square feet. But a formula based on exterior facades for larger buildings allows increased signage.

"I just felt 30 square feet was more appropriate," Elliot said.
