Panattoni Development Company Inc. is adding more buildings to an industrial area on Foothills Boulevard in Roseville, for a project totaling over a million square feet.

Roseville’s planning commission will review a request for a major project permit Thursday for seven buildings on 7601 Foothills Blvd., perhaps best known previously as NEC’s local site.

Tim Schaedler, a regional partner based in Sacramento with Newport Beach-based Panattoni, said he could confirm the proposal. But he said he had no further comment on the project overall.

According to the commission agenda, the seven buildings would range from 401,175 square feet to 34,480 square feet, for a total of 1.08 million square feet. However, three of the buildings, including the largest one, are already built or under construction, according to the agenda. They’re included in the application for consistency with the city’s requirement for a major project permit, for projects of 500,000 square feet or more.

One of those buildings, at 7551 Foothills Blvd., is occupied by Restaurant Depot LLC as a distribution site, while Amazon is working with the city for permits to build a regional distribution center in 28,462 square feet of an existing building. The latter also has an address at 7601 Foothills, for now.

Four unbuilt buildings in the proposal before the commission range from 280,215 square feet to 34,480 square feet. The first and largest building, currently 303,675 square feet, would also grow by another 97,500 square feet.

No tenants are identified in the agenda item. Panattoni would develop the buildings in three phases, with a parking lot built during the first two, and replaced in the last one with a 196,000-square-foot building.

Timing to complete the phases was not spelled out, though work under the major project permit would need to start by Oct. 8, 2022.

Planning staff recommend approval of the permit, with 81 conditions of approval.

Industrial buildings have emerged in recent years as the hottest commercial real estate sector, with explosive growth in e-commerce this year accelerating demand. Many industrial brokers have said newer buildings are especially in short supply, with more firms looking for spaces of less than 100,000 square feet that haven’t been built as much.
