As of June 2020 
Phase: Design

The City has begun work to reduce flooding along NE 148th Street between 12th and 15th Avenues NE. The project was placed on hold in 2016 due to a delay in grant funding from the Washington State Department of Ecology (Ecology). Long-delayed funding is now available.

Design is scheduled for completion in 2020. Construction is planned for 2021.

Currently we are working on:

  • Finalizing project design.

Completed work includes:

Overview and History

Storm runoff on NE 148th Street between 12th and 15th Avenues NE flows to a single catch basin mid-block.  This catch basin has no outlet pipe and is easily overwhelmed. Frequent stormwater ponding occurs within large areas on both sides of NE 148th Street.

This project will improve drainage on this block. Groups of new stormwater facilities will be installed along both sides of the street. These infiltration facilities will capture runoff, store it below ground, and allow it to naturally soak into the soils below. Some of the facilities will have “rain garden” plants at the surface. Others will have hard surfaces which allow for a vehicle to continue parking above. 

Allowing runoff to soak into the ground is one alternative to sending it away within a pipe. If instead a new outlet pipe was used to fix this drainage issue, that pipe would flow into nearby Little’s Creek.  Stormwater runoff from roadways is dirty and scours away the creek during storms. Little’s Creek already has problems with pollution and erosion from runoff, and a new pipe would only worsen things. We wanted to try a solution at this location which would both fix the drainage problem while protecting the creek.

Project pre-design and design was funded by a Stormwater Capacity Grant from the Washington State Department of Ecology. Construction will be largely funded by a SFAP Green Retrofit Grant from the Washington State Department of Ecology.
