Project Overview

Updated December 20, 2017

Environmental Services will begin building your 53 new green street planters in the Argay Terrace Neighborhood in January 2018. The project also includes moving some water pipes, replacing some stormwater inlets and re-constructing some intersection sidewalks and ADA ramps.

When it rains in this neighborhood, water flows over streets, drains into the stormwater system and flows to the Columbia Slough, carrying pollution with it. The green street planters are built next to sidewalks to clean and filter the stormwater before it enters the slough to protect water quality, reduce the risk of basement backups, and help control stormwater runoff during heavy rain events.

Waterline Relocation Schedule

Early January 2018 through the end of February 2018

Environmental Services is coordinating with the Water Bureau to relocate waterlines that will conflict with some green street construction. Residents will be notified if water service will be interrupted. This schedule may change due to a variety of reasons, including conditions underground, weather, subcontractor schedules and availability of materials.

The map below shows where crews will be working.

At this time there is no detailed construction schedule showing sequence of work locations. The city’s contractor will provide notice to adjacent properties before construction begins in each area.

What to Expect During Construction

Expect minor traffic delays, traffic control signage, and flaggers as needed within each work area. For more information, please visit the What to Expect During Construction section of
