The Santa Clarita Planning Commission will consider Westfield’s request for changes to the Valencia Town Center mall to accommodate a Walmart grocery store, when the commission holds its first regular meeting of 2013.

A Walmart Neighborhood Market would be the Arkansas retailer’s fifth store presence in the Santa Clarita Valley, which already sports three regular Walmart stores and one Walmart-owned Sam’s Club membership outlet.

Development plans were initially slated for commission review in October, but mall owner Westfield Town Center Venture LP wasn’t ready to go.

Now it is. Westfield intends to put the grocery store into a vacant, 30,399-square-foot space in the Patios section of the  mall, and Westfield is asking the city to let it redesign the vehicular entry at Valencia Boulevard, the parking lot south of the Patios, and the parking lot south of Sears.

It’s also seeking approval for new shopping cart return areas, an elevated loading dock, and architectural changes to the outside of the building.

The commission will hold a public hearing on the plans Jan. 15 starting at 6 p.m. at City Hall, 23920 W. Valencia Blvd.

At the same meeting, commissioners will reconsider a request from AT&T Mobility to erect two new cell-phone towers inside Canyon Country Park.

Plans call for the replacement of two existing, 22.5-foot-tall light poles with two new light poles that would be topped with cell phone antennas at a total maximum height of 36 feet.

The new poles and a new trash enclosure would be contained within a single structure that’s intended to match the look of other structures in the park.
