The Former Camp San Luis Obispo is located five miles northwest of city of San Luis Obispo, California. The Corps of Engineers is investigating and monitoring the former camp through the Formerly Used Defense Sites (FUDS) Program for munitions and explosive hazards that may remain from previous military activity. This page provides information on the Grenade Courts 25 and 26 project, which is part of the Former Camp San Luis Obispo.
The U.S. Army used Grenade Courts 25 and 26 to train soldiers in the use of hand and rifle grenades. The project area encompasses 53 acres in the southeast portion of the Former Camp San Luis Obispo. In 1992, the Corps of Engineers performed a Time-Critical Removal Action on 95 acres that encompassed portions of Grenade Courts 25 and 26 and the Multi-Use Range Complex project area. The Time-Critical Removal Action was performed to identify and remove munitions and reduce an immediate threat posed by munitions and explosives of concern to people who use the area. During the removal, unexploded ordnance items and expended hand grenade fuzes were discovered in the Grenade Courts project area and disposed of.
Today, the project area is located in the El Chorro Regional Park, which is managed by the San Luis Obispo County Parks Department. Visitors to the park can enjoy a variety of recreational activities, such as touring the botanical garden, camping, golfing, hiking, horseshoes, picnicking, softball and volleyball. The grenade courts overlap portions of the park and botanical gardens.
The Corps of Engineers continues to investigate the Grenade Courts 25 and 26 project to determine if additional clearance work is required. A Remedial Investigation and Feasibility Study Report is being prepared, which will provide a characterization of munitions that may remain and an evaluation of potential remedial alternatives for the project.
