Rehabilitation of the Oak Creek 2450-millimeter (96-inch) Storm Drain, a Cast-in-Place Concrete Pipe System, Riverside County, California

In 1988 the Oak Creek Storm Drain, a 2450-mm (96-in.) diameter concrete pipe, was designed and constructed as part of a subdivision development in Murrieta, California. The pipe was specified as reinforced concrete pipe (RCP) with a cast-in-place concrete pipe (CIPCP) alternative as allowed by Riverside County Flood Control District specifications. The contractor chose the CIPCP alternative because it was more economical. The site soils were classified as compressible alluvials over weathered bedrock with some groundwater. The geotechnical engineer specified removal of the alluvials, placement of a subdrain, and replacement of the removal with engineered fill. The contractor excavated and constructed the specified subdrain and then excavated for the CIPCP construction. The contractor did not excavate and remove all the alluvial materials within the CIPCP structural envelope. This resulted in a soil environment not competent for CIPCP construction. Expectedly, after backfill, the pipe experienced structural cracking with some displacement. This paper describes the rehabilitation investigation, design, and construction that restored the existing pipe to function as designed for the expected service life.
