The project consists of the construction of a new stormwater pump station and support structure at an undeveloped city owned site, located at the approximate location of 560 Washington Avenue South, adjacent to the Green River at the southeast corner of Washington Avenue South and Hawley Road in Kent, Washington. Surface features to be constructed include, the pump station, submersible pumps, variable frequency drives, wet-well, gravity discharge structure, the pump station control panel, shelter, paving, fencing, and landscaping. The project also includes the installation of underground facilities including stormwater conveyance piping, catch basins, and other underground structures to facilitate the construction of the new stormwater pumpstation as well related sanitary sewer relocation work and pavement restoration. As part of the pump station discharge piping, the contractor will be required to excavate into and restore the Hawley Road Levee. This work on the levee shall not occur during flood season. The project will also include all related temporary dewatering, erosion control, and work zone traffic control.

Due to supply chain considerations, the City has procured some of the pipe to be used in this project for installation by the selected contractor.
