Alverson Stormwater Separation Project
A project to end chronic basement & surface flooding
The project is located in the Northwest neighborhood. The work includes construction of a separated storm drainage collection system that will convey stormwater flows to detention ponds on the Legion Memorial Golf Course site. A schematic of the proposed storm drain system is shown in the Project Area map. Alverson Stormwater Separation project is Phase 3 (the final phase) of a project formerly called "Northwest Neighborhood Stormwater Separation (NWSS) Project." The project is now divided into three parts:
- Legion Golf Course Stormwater Detention Project
- North Wetmore Stormwater Separation Project
- Alverson Stormwater Separation Project
Construction started on the new storm drainage network in May of 2018 in the North Wetmore Stormwater Separation project area. The Alverson project will tie into the pipe installed by the North Wetmore project and will complete the stormwater separation work for the upstream portion of the network, along Alverson from 5th Street, to Grand Avenue and 9th Street.
Property owners in the vicinity of the Alverson project are encouraged to redirect their property's drainage to the new storm drain system. If you would like to discuss reconnecting to the new system or other drainage issues in the vicinity of the project, please contact the City's Project Manager shown to the right.
The City completed preliminary planning to define sewer and drainage system improvements needed for elimination of basement flooding and surface flooding in the area of Alverson, Grand, Rucker, Hoyt, Colby and Wetmore between 4th and 10th Streets and at Everett Community College Rainier Hall. The study determined that a new separate storm drainage network should be constructed in this area – similar to the work done in the nearby Sewer M area to the south, however, no sewer replacement is needed.
Although these improvements are primarily to minimize or eliminate basement and surface flooding, they will also help the environment by reducing combined sewer overflows into the Snohomish River. The project will benefit from the collaboration of several stakeholders: City of Everett (Public Works), City of Everett Parks/Legion Memorial Golf Course and Everett Community College.
