Green Island Logistics Center, formerly called Giovannoni Logistics, is a warehouse and industrial park at Green Island Road and Highway 29 in American Canyon. The city's September 2026 inventory lists two proposed changes from the developer, Buzz Oates. Neither is shown as approved.
The proposed changes
- Lot 2 modification: replace three buildings (503,050 square feet) with two (471,332 square feet). Those figures cover Lot 2 only, not the whole park.
- Lot line adjustment: move an interior parcel line to create a separate lot for Building B.
Background
Barry Eberling reported in the Napa Valley Register on November 18, 2022 that Buzz Oates proposed a 208-acre project near Green Island and Devlin roads. It would have about 2.4 million square feet of warehouses, built in two phases. The Center for Biological Diversity said the plan did not do enough to offset the loss of wildlife habitat. Others questioned the environmental review and traffic.
The city's list also shows a mass-grading application for 70.2 acres of the project. In October 2024, the applicant put it on hold, citing market conditions.
What we don't know
We have not confirmed approval of either change or any current construction. The 2022 report predates the current proposals, and the city list is from September.
How we know (5 sources)
Dated source evidence; the project may have changed since then. An approval does not establish construction or an opening.

The city’s September 2026 inventory lists two changes proposed for Green Island Logistics Center, formerly called Giovannoni Logistics: a parcel adjustment for Building B and a modification replacing three buildings on Lot 2 with two. The modification describes a change from 503,050 to 471,332 square feet; those figures concern the proposed Lot 2 layout, not the entire logistics park. Buzz Oates identifies the larger project at Green Island Road and Highway 29 in American Canyon. These application entries do not establish approval of the changes or current construction. The saved September inventory could not be refreshed during this review.
