The south half of the roadway has a complete layer of pavement!
Today the remaining portion of the eastbound lane was paved along with the 222nd Pl SE intersection approach. Vehicles can once again drive the whole length of the project on pavement; while there is some underground work still remaining, enough has been completed that roadway grading can continue. Crews will now be focusing their effort on the north half of the roadway to get the remainder of the roadway paved. In the next few weeks the roadway is going to see significant change. Starting Monday, September 16 crews will begin pulverizing the existing pavement and placing the rock base layer for the new roadway. Once the pavement is placed, traffic will drive on the new pavement will while work continues on the north half.
228th Intersection Construction - was schedule to take place in August, but has been delayed to address an underground utility conflict and focus on getting the rest of the road ready for a new layer of pavement before the rainy season hits.
The following is a summary schedule of active work (subject to change due to weather and typical construction issues that often arise).
Roadway Grading - Grading for curb, sidewalk and pavement on the north half of the road will continue through November. A layer of pavement will be placed on the north half in early December.
Sidewalks - Work to place the decorative sidewalk in the Town Center area will begin in late November.
Stormwater - Most of the storm water system has been installed.
Traffic Control - Hours of construction work are typically Monday to Friday 7:00am to 5:00pm. During these hours flaggers will be controlling traffic through the construction zone. Depending on the construction work there will be times with significant travel delays. Please plan accordingly and consider using alternate routes during hours of construction. We recommend driving around the project during hours of work as travel delays due to construction activities will be ongoing and the roadway is quite rough due to all of the construction work.
Construction Schedule - The chart below shows the general anticipated timeline and progression of work. There are many moving parts to the project and work activities may sometimes happen out of sequence due to the need to work around unforeseen issues that could not have been anticipated, e.g. hidden subsurface objects, locally varying soil conditions, weather, etc.
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.

The preliminary project estimate is $13,250,000. This includes cost for construction, engineering, and right-of-way. Cost to underground overhead utilities has not yet been determined.
*In August of 2015, the City applied for a Transportation Improvement Board (TIB), Urban Arterial Program Grant to assist with funding this project. TIB selected this project for funding November 2015. As part of the grant requirement, funding for the project must be certified by November 20, 2016, and construction is expected to begin in 2017 or sooner.SE 4th 2015 TIB UAP Application.pdf
On June 7, 2016 - the project team provided City Council with an update on the project design. City Council recommended that a public meeting be held prior to continuing with final design.

November 2016 Project Update
Project design is at 60 percent complete and has begun the right-of-way acquisition and environmental permitting processes. The following file is a copy of the draft Right-of-Way plans.
September 2017 Project Update
Project design is complete and ready to be advertised for construction. We are currently waiting for the US Army Corps of Engineers to complete an environmental permit review and working on the completion of a few remaining few remaining acquisitions for the necessary road right-of-way. Once these items are complete the project can be advertised for construction. We are anticipating that this will occur by November 2017.
February 2018 Project Update
Construction bids are currently being requested for the project. Bids are due to be opened on February 21st. 2018. Construction activities are anticipated to start mid-Spring of 2018 and go through Spring of 2020. Copies of the construction plans are available at Builders Exchange.

Sammamish Plateau Water will be installing sanitary sewer along SE 4th St as part of this road improvement project. The proposed sewer extending to the north and south will be built separately as development occurs. A conceptual sewer plan has been developed by SPW. For additional information regarding the water and sanitary sewer utilities, please email SPW's project manager, Jackson Dove (email@example.com) or call him at (425) 392-6256.
