475 E San Francisco Avenue

The property at 475 East San Francisco Avenue (SF Avenue Property) is approximately 1.5 acres in size. It is located approximately three blocks east of State Highway 101 and one mile northeast of the former Remco Hydraulics Facility. Its closest neighbors include residences and a lumber mill and storage yard.

Remco Hydraulics, Inc. (Remco) conducted gun barrel manufacturing on the SF Avenue Property for the U.S. Government from June 1973 to June 1978. The property usage history follows:

• Prior to 1960, the property was used by the neighboring lumber mill for storage.
• From the early 1960s to 1966, watercraft toilets were manufactured on the property by Microphor, Inc.
• From June 1973 to June 1978, Remco manufactured 90 mm and 105 mm recoilless rifles for the U.S. Government.
• Some time after 1978, a fire destroyed the southern portion of the warehouse.
• No information was found regarding activities at the SF Avenue Property from 1978 to 1991.
• From 1991 until 1999 the property was used for recycling of household products such as glass, plastics, and paper products.
• From 1999 to the present, the property has been used for the storage of gardening supplies.

Remco's manufacturing activities included: machining of raw metal with lathes, milling machines, and a broaching machine; quality control inspections; and rifle assembly without the firing mechanism. No chrome plating was conducted at the SF Avenue Property.

In 2001, the Willits Trust started investigating the property, resulting in numerous reports documenting site conditions and a 2004 risk assessment report. Based on this work, the RWQCB issued a 'No Further Action' designation letter in March 2008 indicating that no additional work or remediation is required at this property.

Further information regarding these activities can be found on the Document Depository.
