SE 4th Street Improvement Project

180612 Tree Clearing (1).jpg

Project Update:

June 15, 2018

The SE 4th Street landscape is changing.  Crews are clearing the "footprint" of the new roadway.  It will look significantly different.  The old sixty feet of road right-of-way currently seems narrow since the only hard surface is the twenty feet of pavement and only had room for cars.  The new road right-of-way will be approximately seventy feet wide and will have space for people, bicycles, and cars.

The roadway clearing is expected to run most of July.  Utility Trench installation will be starting in the 218th Ave SE and SE 4th St intersection soon after the clearing work begins.  Flaggers will be directing traffic through a shared lane during this work.

Below are two conceptual images of what SE 4th St will look like once complete. The upper image represents the commercial area in the Town Center.  The other represents the westerly portion of the project which has an urban residential quality. (The photo above was taken June 1, 2018.)

Summary

The SE 4th Street Improvement Project is a critical component to support the City's Town Center plan. It will develop SE 4th St between 218th Ave SE and 228th Ave SE into a multi-modal corridor to meet concurrency requirements and provide increased opportunity for access and development within the core mixed-use area.

The existing road consists of two travel lanes with narrow shoulders and no sidewalk. The proposed road will be developed to include two travel lanes, a center turn lane or median, bike lanes, planter strips and sidewalk. This project will also coordinate the installation of upgraded Sammamish Plateau Water and Sewer District utilities with the roadway construction.
