Construction Starting in Seal Beach

Post Date:03/26/2020


The Orange County Sanitation District is designated as critical infrastructure and essential services, which are imperative during the response to the COVID-19 emergency and will continue to operate.


The Orange County Sanitation District will be starting construction on the Westminster Blvd. Sewer Project taking place in the cities of Seal Beach and Westminster on nearly three miles of regional sewer pipelines. 

Starting Location 

Westminster Blvd. between Seal Beach Blvd. and Bolsa Chica Rd. in the City of Seal Beach.  It is approximately a 2-mile stretch of construction activity before work commences in the City of Westminster starting at Bolsa Chica Rd.

3-62 Starting Location


The first portion of work along Westminster Blvd. between Seal Beach Blvd. and Bolsa Chica Rd. will start as early as the week of April 6, 2020 and last through late 2021.  The project as a whole is anticipated to be completed late 2022.

Scheduled work hours are Monday through Friday, 5 a.m. - 7 p.m.

Some locations will require night work hours and notice will be provided.

*Dates and times are subject to change due to operational factors or inclement weather.

What to Expect

Most work in the Seal Beach city limits will be within the center median. Preliminary construction activities will include widening the roadway, restriping traffic lanes, and installing k-rail to accommodate construction in the center median area.  The bike lane will be closed during the planned roadway paving activities.  

Two lanes of travel in each direction will remain. Expect periodic traffic delays and restrictions reducing the number of open travel lanes during non-peak traffic hours.

Project Description:

The project will replace and reconstruct nearly three miles of the existing sewer force main system consisting of two parallel 36-inch diameter sewer pipelines on Westminster Boulevard between Seal Beach Boulevard and Rancho Road/Hammon Place in the cities of Seal Beach and Westminster.

A force main system are pipes used to move wastewater under pressure by use of a pump station. Force mains are necessary when gravity flow is not sufficient to move wastewater.

This project is within the Western Regional service area.
