Sewer System Improvements “M” Project
Construction: Phase 1 Construction to begin soon. See Notice.
The project area is generally west and south of Providence Regional Medical Center, Everett (PRMCE) with boundaries as follows: north at 10th Street, west at Grand Avenue, south varies between 17th and 19th streets, and east varies between Colby and Rockefeller avenues. The total project area consists of approximately 30 city blocks or 112 acres and is almost exclusively single family residential neighborhoods and all within the NW Everett Neighborhood.

Address Basement Flooding Problems:
The primary objective of this project is to address chronic basement flooding problems in the vicinity of Colby and Hoyt avenues and 15th Street. This map shows addresses in the project area that were flooded during the August and September 2013 rain storms.
New storm drainage pipe would be extended and catch basin inlets constructed at most intersections throughout this project. This new storm drainage network would effectively separate stormwater runoff from the sewer collection system. Work would be done by open-cut methods. In addition, the City will be asking homeowners to disconnect rain gutter downspouts from their side sewer pipe wherever possible. Click the link for more information on disconnecting downspouts.
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. Approximately 12,000 feet of old combined sewer main and 500 side sewers could be replaced by this project. Most of these collection sewers are located in alleys. Work would be primarily by open-cut methods.
Streets that are impacted by the construction work are likely to be replaced with full-width asphalt paving including new curbs and sidewalks where necessary. Some streets may be patched and overlayed. Alleys will re-paved with full-width asphalt. Click the link to view an exhibit showing the proposed restoration work for the Phase 1 project.
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 replaced. 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. The utility bridge will also have improvements for pedestrian use.
Public Information and Relations:
The City anticipates holding a neighborhood open house meeting in January 2015 to present information about the Phase 1 project and address questions from the residents of the project area prior to construction. Mailings will be sent out announcing meetings and furnishing updated information.
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.
