Volunteers from the U.S. Army Corps of Engineers partnered with the Waikiki Improvement Association, the Hale Koa Hotel and other concerned citizens to participate in the Waikiki Beach Clean-up on April 27 as part of Earth Day 2013. Approximately 20 volunteers from the Punahou Junior ROTC program (which includes cadets from other area high schools and some home-schooled students) and Corps’ employees and family members joined forces to clean up the beach and berm area and plant decorative plants donated by the Hale Koa Hotel at the Corps’ Pacific Regional Visitor Center (RVC) at Fort DeRussy in Waikiki. Altogether about 50 volunteers participated. The RVC is located on the second floor of historic Battery Randolph at Fort DeRussy. Battery Randolph is listed on the National Register of Historic Sites and is one of 16 coastal fortifications built by the Corps between 1906 and 1917 for the protection of Honolulu and Pearl Harbors.
