Dear Ms. Nelson,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located Formerly Classified Harbor Defense Files, 1918 - 1945 in the Records of the Office of the Chief of Engineers (Record Group 77) that includes records pertaining to Roosevelt Roads in Box 128. We also located General Correspondence with Districts, 1941 - 1945; Formerly Security Classified Subject Files, 1940 - 1945; and Correspondence with District and Other Field Offices, 1923 - 1942 that include records relating to the Puerto Rico Engineer Office. For the series that are arranged according to the War Department Decimal File System, we suggest that you begin by looking under the decimal file number 230 - Civilian Employees. For more information, please contact the National Archives at College Park - Textual Reference (RDT2) at email@example.com.
In addition, we located Civil Works and Military Construction Projects, 1899 - 1950 and Correspondence Relating to Civil and Military Construction Projects, 1941 - 1950 in Record Group 77 that may include relevant files.

If you know the name of an engineer that was employed by the U.S. Army Corps of Engineers as a civilian employee, we suggest that you request a copy of his Official Personnel File (OPF). OPFs and medical information for individuals who worked for the U.S. government in a civilian capacity before 1952 are in the custody of the National Archives at St. Louis (RL-SL). Please email RL-SL via email at email@example.com and include the full name used during Federal employment, date of birth, Social Security Number (if applicable), name and location of the employing Federal agency, beginning and ending dates of Federal Service. For more information, the web site is https://www.archives.gov/st-louis/opf.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2, RE-NY, and RL-SL. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your research!
