City Sewers Completed Construction

Flower Street Replacement Sewer Project

Inspections showed that portions of the Flower Street sewer, built in 1894, had seriously deteriorated. Also, the MTA Blue Line Light Rail track was built on top of the sewer, limiting access to City maintenance crews. The City of Los Angeles Department of Public Works replaced this sewer beginning in February 2006. The new sewer was built under S. Flower Street, west of the MTA tracks, from W. Washington Blvd. to W. Pico Blvd. Workers used open trench and hand tunneling methods to build the new 2,000-foot long sewer.

Crews dug the main trench, position, and connect the sewer pipes during daylight hours. For the safety of the construction crews, other work took place at night and into the early morning hours. This includede reconnecting some of the smaller sewer pipes from adjacent properties to the new main sewer. The contractor and the City kept noise to a minimum during this work.

The contractor’s work plans included many controls to also minimize dust and traffic impacts. Businesses on the west side of S. Flower Street had mostly normal access to their properties. East side businesses also had normal access through the use of their usual alleyway entries off Pembroke Lane. Open trenches along Flower were covered with steel plates that allowed entry to properties and parking during construction. Temporary blockage of these areas did not exceed two hours.
