The Orange County Sanitation District has requested our help in obtaining feedback about a major construction project coming to our area in 2020.  The project is called the Western Regional Sewer Program.  The section impacting our neighborhood will make improvements to two parallel sewer lines along a two-mile stretch of Seal Beach Blvd/Los Alamitos Blvd. from just north of the I-405 freeway to Katella Avenue in the cities of Seal Beach and Los Alamitos. Also being repaired is the sewer on Katella Avenue from Oak Street to Lexington Drive. About 65 manholes will also be replaced or rehabilitated

The sewer lines suffer from corrosion and must be fixed to extend their service life. Once fully repaired, the lines will remain operational for another 50 years. Your input on this survey is important to helping make the construction as easy as possible on the community.  For more information about the project and to assist OCSD in planning, please take a few minutes to take a community survey at
