Sewer System Improvements M, Phase 2

A project to end chronic basement & surface flooding

Construction Schedule—Updated May 23, 2017

Phase 2 is being constructed by KLB Construction and is expected to be completed by June 2017. Restoration and cleanup will occur May through June. The restoration work will cause some on-street parking restrictions.


: Please see attached notice about on-street parking restrictions beginning May 30. Notice regarding Final Paving Schedule and Map (PDF)

Restoration work (street or alley paving, sidewalks, ADA curb ramps, landscaping or lawn repair etc.) will generally be done on an ongoing basis during the remainder of the project.  The schedule is subject to adjustment based on weather conditions, or other unexpected complications. Residents will be notified in advance of street or alley paving activities and related vehicle access and parking restrictions. Drivers and pedestrians should be alert for traffic control signs and flaggers throughout the project area.

Address Basement Flooding Problems

The primary objective of Sewer M phases 1 and 2 are to address chronic basement flooding problems mainly in the vicinity of Colby and Hoyt avenues and 15th Street but also in other locations nearby. New storm drainage pipes are being extended and catch basin inlets constructed at most intersections throughout this project. This new storm drainage network effectively separates stormwater runoff from the sewer collection system. In addition, the City is asking homeowners to disconnect rain gutter downspouts from their side sewer pipe wherever possible. Learn more about the downspout disconnect program.

Replace Old Sewers

In addition, many existing sewers, manholes, storm drain structures and side sewers in this area are very old and deteriorated or undersized and should be replaced soon. Most of these collection sewers are located in alleys.

Control Combined Sewer Overflows (CSO)

An existing CSO pipe at 15th Street and Grand Avenue that periodically conveys excess wet weather flows from the neighborhood collection sewers to Port Gardner, was damaged by a landslide that occurred in the December 2012 to January 2013 timeframe and needs to be abandoned. The City will be replacing that CSO pipe and another old pipe at 14th Street by constructing a new utility bridge at 16th Street extending across the Burlington Northern Santa Fe rail yard and West Marine View Drive. Several pipes will be installed on the bridge to convey stormwater, combined sewer overflows and pumped sewage from the marina area. The utility bridge will also have improvements for pedestrian use.

Community Project Liaison

The City of Everett is providing a full-time construction/community project liaison (CPL). This person will be the primary contact person responsible for addressing the needs of residents, businesses, etc. affected by the construction project activities. The CPL's role is intended to provide a single, responsive point of contact for the public who will be readily accessible by telephone or in person during normal business hours and during all hours of work throughout the duration of the project.
