1. Is the Concord Naval Weapons Station (CNWS) closed?

The base is divided into two areas: the Inland Area and the Tidal Area. The Inland Area is located in the northeast section of the City of Concord and contains bunkers and limited administrative and testing facilities. The Tidal Area fronts on Suisun Bay and contains a port and industrial buildings used by the Army as the Military Ocean Terminal Concord (MOTCO). The Inland Area was included on the 2005 Base Realignment and Closure (BRAC) list, and the Navy has ceased operations there. Although it is officially closed, the Inland Area will remain under Navy ownership until various Federal regulatory requirements are completed and the property is deemed suitable for transfer. The Tidal Area is not under consideration for closure and remains in operation today, having been transferred from the Navy to the Army.

2. How big is the Concord Naval Weapons Station?

The former CNWS covers nearly 12,800 acres, or approximately 20 square miles. An acre is about the size of a football field.

The Inland Area is approximately 5,028 acres, or approximately 8 square miles.

The Tidal Area is approximately 7,630 acres, or approximately 12 square miles.

This property has been transferred from the Navy to the Army along with 115 acres in the Inland Area. It is currently operated by the Army as the Military Ocean Terminal Concord (MOTCO).

5. What activities are currently occurring on the site?

Although the Navy has vacated the former CNWS and access to the site is controlled, a variety of activities are taking place before land begins to transfer from the Navy to the City. Some activities are related to preparing the site for transfer, such as environmental monitoring, remediation and clean-up. Other activities include cattle grazing and, in parts, autonomous vehicle testing.

6. Who currently owns the former CNWS?

The U.S. Navy owns the Inland Area of the former CNWS. The Tidal Area, plus a small parcel of land adjacent to the Navy’s property, is owned by the U.S. Army.
