The Mushroom Express facility is a five acre parcel of privately held fee land that is located within the exterior boundaries of the federal Rincon Indian Reservation in San Diego County, California. The non tribal facility has functioned as a mixed use commercial site for a number of years. Mushroom Express operated as a produce transportation and mushroom growing business. The parcel contained two 17,500 concrete block buildings for mushroom growing operations and one of the structures also contained several apartments. In addition, the owner leased open space to several tenants for truck/trailer storage, equipment storage and a separate towing/impound business.
The site was devasted by the 2007 Wildfire event and is currently being evaluated by EPA.
