Sharon Caine, U.S. Army Corps of Engineers Sacramento District real estate division chief, is seen here in the mid 1960s while working in the district’s engineering division, civil defense branch. At that time, the district surveyed buildings to determine suitability for fallout shelters. Caine will retire at the end of 2014 after having served the U.S. Army Corps of Engineers for 54 years. Most of that time was spent with the Corps’ Sacramento District.
