CHINA -- Planning Board members unanimously approved a permit Tuesday evening for a new Hannaford supermarket in South China.

Approval comes with numerous conditions. All the conditions have been discussed at previous meetings, and all were accepted by Hannaford representatives at Tuesday's meeting.

The 36,000-square-foot supermarket and a separate 20,000-square-foot retail building will be constructed on the east side of Windsor Road, not far from the Route 3 intersection.

One condition is that Hannaford return to the Planning Board for approval of any proposed businesses in the second building.

Another governs hours when the Hannaford can be open to the public.

The store can operate from 7 a.m. to 11 p.m. , according to the Planning Board, but employees, contractors and vendors may be there at any time. Hannaford has the option to return to the Planning Board to request a change in store hours.

The project includes installation of a traffic light at Route 3 and Windsor Road and other changes to local roadways.

Other conditions require Hannaford to do a traffic impact study within a year after the store opens, and to establish a $20,000 escrow account to pay for any measures needed to mitigate traffic changes caused by the business.

The company has also agreed to conservation easements to protect about 120 acres the company owns behind the store site, east of a stream that divides the property.

Code Enforcement Officer Scott Pierz said there is a 30-day window during which the Planning Board's decision can be appealed.

Mitchell Feeney, one of Hannaford's representatives at Tuesday's meeting, said the company still needs a permit from the state Department of Environmental Protection before ground breaking can be scheduled.

Feeney has said previously that, once all permits are acquired, preliminary site work should take about two months and construction of the building about another nine months. Off-site work, such as adding the traffic light and making other planned changes on Route 3, would be done at the same time as on-site work.

The company also worked with the town's fire chief on where to site hydrants.
