BACKGROUNDThe residential area of Treasure Island was originally used as a parking lot during the Golden Gate International Exposition from 1939 through 1940. Following the establishment of Naval Station Treasure Island, the area was developed for bunker storage of munitions and other materials, vehicle and equipment storage, recreational playing fields, and disposal and burning of waste. Beginning in the 1960s, the area was developed into housing for Navy personnel. Naval Station Treasure Island was operationally closed in 1997. In 1999, at the request of the City of San Francisco, the Navy leased the majority of the former military housing to the City. The City then worked with several affordable and market rate housing providers to rent the units to residents.

In 2007, the Navy discovered radiological objects while removing contaminants from solid waste disposal areas along the outer perimeter of the residential area. Since 2007, the Navy removed several buildings and concrete foundations in preparation for further removal of the known solid waste. In March 2013, the California Department of Public Health conducted a radiological survey of the roads and open spaces within the residential neighborhood, covering areas outside the solid waste disposal areas. In the fall of 2013, the Navy conducted additional comprehensive surface surveys of the roadways, carports, open spaces and backyards of all residences. The preliminary results of these surveys were reported at the February 2014 Restoration Advisory Board meeting and the Navy will release comprehensive reports on the surveys later this year.

RADIOLOGICAL SURVEYSBeginning in June 2014, the Navy, in close coordination with the California Department of Public Health, will be conducting radiological surveys inside the ground floor of residences. This survey will collect data representing the area under the concrete foundations. This survey will focus on the ground floors of every residence (including garages and storage lockers) and will allow the Navy and the State of California to verify everyone’s safety.

WHAT IS THE PROCESS?The surveys will be conducted by a radiological technician who will survey the floors of the residences, garages, and storage lockers. The technician will use a survey meter (see photo) to cover all the surface area of the ground floor rooms in each residence. Another trained team member will record the data. To allow for the complete floor area to be surveyed, teams will carefully move large furniture and other items that would otherwise prevent the collection of data. In most cases, this may mean moving furniture a few feet to allow access to that portion of the floor. In some cases, furniture will be temporarily moved outside the residence. Moving blankets and plastic sheeting will be used for protection of residents’ property. All of this will be done in the presence of a field team supervisor. Housing service provider representatives and Navy personnel will also be on site. Residents are welcome to be present during the surveys.

Surveys will be conducted using the Ludlum Model 193-6 – a highly sensitive portable gamma radiation survey instrument. The instrument will detect if there are any radiological materials or items painted with radium paint below the building foundation.

A total of six separate survey teams will be working at Treasure Island to complete the surveys as efficiently as possible. All surveys are anticipated to be completed within four months. Each residence may take from 2 to 4 hours to survey. It is possible that some residences will take longer. For residences with garages, it will be necessary to have access to the garage and driveway for efficient, temporary moving of items. The second floors of all residences will not need to be surveyed.

WHAT CAN RESIDENTS DO TO PREPARE?• Please secure any pets upstairs or in backyards on the day your residence is

scheduled. This will allow the team to complete the survey quickly and safely and ensure the safety of your pet.

• Secure your valuables • Box up fragile and breakable items that you do not want movers to handle• Move items upstairs if possible – upstairs areas will not require surveying• Discuss the surveys and this fact sheet with other household members

including children • For garages and storage lockers: Organize material in boxes so it can be

safely moved

RESULTSAt the completion of the radiological survey, all furniture and personal belongings will be returned to their original locations within the residence. The Navy will process survey results within two weeks from the date of the scan and then provide the results to the Treasure Island Development Authority (TIDA) for distribution. In order to accurately process the survey results, the information must be thoroughly reviewed and validated in coordination with the California Department of Public Health. It may be possible that survey results will be available before the two week period and if that is the case, the results will be provided to TIDA earlier.

SCHEDULESurveys will be conducted between the hours of 8:00 am and 5:00 pm, Monday through Friday. No weekend work or work on holidays will be conducted.

Surveys are currently scheduled to begin on June 12, 2014 and continue through September 2014. Residents will be informed of the date their residence is scheduled for the survey. A Work Notice will be sent to each residence two weeks before the survey. This notice will list a timeframe for your residence to be surveyed. The Navy will coordinate final scheduling with TIDA and the housing providers. An additional notice will be provided to each residence a minimum of 24-hours before the survey. It is your right and your choice to be present during the survey. A representative of your housing provider will also be present during the survey.

FOR MORE INFORMATIONContact the following Navy representative with site-related questions or concerns:

The Ludlum Survey Meter is a portable detector that is designed to detect gamma radiation. Gamma radiation is similar to the type of radiation used for X-rays. This type of detection equipment can identify the type and level of radiation down to very small levels.
