Regional sewer pipeline rehabilitation on the Newport Blvd. Sewer Project is underway.  Continue reading for more information.

This month, three pits will be excavated (two on Newport Blvd. and one on Short St.).  The pits are being excavated down to the existing regional sewer pipeline located under the roadway.  Sections of sewer pipeline will be rehabilitated from pit to pit using the cured-in-place pipe method which will require around-the-clock activities.

Starting November 5, southbound Newport Blvd. will be reduced to 2 lanes when work takes place for pit excavation.   

Starting November 13 for about two weeks, Short St. will be closed at Newport Blvd.  Detours will be via Finley Ave.  The Short St. closure is necessary due to the location of one of the excavation pits. 

During the week of November 13, nearby residents and businesses will notice 24/7 work taking place for cured-in-place pipe construction activities.  There will be continuous lane closures to accommodate the work.  A liner is inserted into the pipeline and cured with hot water for a period of 36-hours.  Once the liner has been inserted, work cannot be interrupted in order to properly cure the liner and complete the work, requiring continuous work hours.  Work will occur through the night and extend through the weekend.  There will be two separate locations for 24/7 work, lasting approximately 2-3 days at each location.

There will be an increase in noise and activity.  Some noticeable equipment during cured-in-place pipe include a scaffold tower (see photo above), water boiler, generators, and lights.  Lights, when in use, will be directed away from windows to minimize the effect to our neighbors.  Read the latest construction alert distributed to nearby residents and businesses. 

Major construction efforts are anticipated to be completed by the Thanksgiving weekend, with restoration work completed in December before the holidays.

In addition to OCSD's sewer project, the City of Newport Beach is near completion of water line construction on Short St.  The City anticipates final street paving to occur after the holidays.   

North of PCH

The cured-in-place pipe activities that recently took place to rehabilitate an existing sewer pipeline was successful.  Construction work continues along the shoulder of northbound Newport Blvd. near Industrial Way.

Upcoming manhole rehabilitation work will take place in the City of Costa Mesa starting in December.

Project Description:

The Newport Blvd. District 6 Trunk Sewer Relief construction project will replace an existing 60 year old regional sewer pipeline with a larger sewer pipeline to increase the sewer flow capacity and reduce the risk of spills.  Construction will take place along Newport Blvd. between Pacific Coast Highway and Industrial Way in the City of Newport Beach and Pomona Ave and 17th St in the City of Costa Mesa.  

Additional work will take place along Newport Blvd. near Via Lido (not shown on map).
