Expect more big trucks on the move in Deltona.

Another huge building is now under construction, just across the road from the Amazon fulfillment center.

The million-square-foot high-cube warehouse will be the centerpiece of I-4 Logistics Park, which is part of the greater Portland Industrial Park, now anchored by Amazon and bisected by North Normandy Boulevard.

I-4 Logistics Park is to be a 128-acre industrial complex that will also include two 500,000-square-foot buildings. The project includes outparcels for retail stores or restaurants.

An Atlanta developer, Seefried Industrial Properties, is the owner of the new building, as well as the Amazon complex.

As for the future occupant of the enormous building being constructed, no names have been mentioned, but Deltona Acting City Manager John Peters said he has heard of three parties that may be looking at moving in. Completion of the new building is several months away.

In nearby DeLand, another industrial project may be on its way. DeLand Tech Park is a 143-acre industrial and business park planned for construction near the intersection of State Road 472 and Interstate 4 on DeLand’s south side.

DeLand Tech Park was approved by the DeLand Planning Board July 20.

A chunk of the project will be two buildings, each smaller than Amazon’s more-than-1,000,000-square-foot fulfillment center. If approved by the DeLand City Commission, the buildings will be 750,000 square feet and 500,000 square feet, respectively.
