SAN DIEGO, CALIFORNIA — U. S. NAVAL SUPPLY DEPOT FUEL FACILITY 

 AND THE U. S. NAVAL STATION 



Ak^ . 01 Location of the Test Stations and Test Boards 



Test "boards of the panel type were installed on July 1?^ 19^^> 

 at the U. S. Naval Fuel Annex (changed to U. S. Naval Supply Depot 

 Fuel Facility in 19^7) and on August 5> 19^^, at the U. S. Naval Repair 

 Base (nov the U. S. Naval Station) in San Diego Bay, at San Diego, 

 California. The first of these, designated hy the symbol USNSD-1, 

 vas Installed at the northern end of the T-shaped Fueling Pier at the 

 Fuel Facility. The second, designated "by the symbol USNSD-2, was 

 installed on the south side (outhoard end) of the south Mole Pier at 

 the N?ival Station. As all piles used in waterfront structures at 

 this Station are either concrete or treated Douglas fir, it was Im- 

 possihle to locate the test "board adjacent to untreated piling. 



Because of disintegration of the test "boards and extreme high 

 tides during the last week of June 19'*-6, "both "boards were lost. On 

 account of the severity of the marine "borer attacks at these locations, 

 it was requested that the new "boards of 4-panel series "be installed 

 so that the panels would be submerged on a ^-month: "basis Instead of on 

 the 8-month "basis which was "being en?)loyed . Thfese were Installed 

 in August at the Fuel Facility, and proha'bly in July at the Naval 

 Station. The operatloia of these test "boards- is "being continued and 

 the results of these tests have "been summarized to the end of 19^7. 



A14-5 . 02 Hydrographic Data 



1. USNSD-1 (U. S. Naval Supply Depot Fuel Facility) The depth 

 of water where this test "board was installed was 29 ft; the tidal range 

 was 10.28 ft (from -2.12 to -8.l6); the velocity of the current was 

 unknown. The temperatiire of the water at the time of installation was 

 66° F, and the water was clear with the exception of the occasional oil 

 pollution caused by fueling activities. 



2. USNSD-2 (U. S. Naval Station) . The depth of water where 

 this test board was Installed was 17 ft; the tidal range was 10.28 ft 

 (-2.12 to /8.l6); the water was quiet. The temperature of the water 



at the time of Installation was 72° F. Pollution was said to be negligible, 

 the water being clear. However, the surface of the water subsequently 

 was variously reported to be clear, slightly oily, not too dirty or 

 oily, and with an oily, dirty, dark color and traces of oil. On August 

 7, 19^6, it was reported that marine growths were "blooming." 



Further data on the te3]5)erature and salinity of the water at this 

 location are given in the following tables.
