18-17: Jefferson Street Area Reconstructions

Project Location

This project will reconstruct Jefferson Street from 119th Avenue NE to 104th Court NE.

Project Description

Improvements include spot repair/replacement of concrete curb and gutter and sidewalk, storm drainage improvements, spot sanitary service repair, raw water interconnect, spot water main repair, asphalt surface replacement, traffic control signage, and appurtenant construction.

The project year breakdown is as follows: 2019-Construct Jefferson Street from 112th Avenue to 119th Avenue. 2020-Construct Jefferson Street and 104th Court from 104th Court to 112th Avenue.

The project will fully reconstruct Jefferson Street with new pavement and concrete curb and gutter and additional storm sewer infrastructure at select locations. Watermain work will be generally limited to hydrant replacements, curb stop repairs and replacement of select watermain valves. No sanitary sewer work is anticipated. The street will remain the same width and configuration as it currently is. The general construction process is as follows:

The existing pavement surface will be ground up into gravel and existing curb and gutter (if present) will be removed. Spot sections of damaged or settled sidewalk will be removed.
Underground utility work will be constructed where planned.
The gavel road base will be graded and shaped and new concrete curb and gutter will be poured along with replacement of removed sidewalk sections.
After the concrete curb and gutter has cured, the first layer (base course) of the new bituminous street surface will be paved.
The second layer (wear course) of the bituminous pavement will be paved.
Boulevards will be restored and sodded.

It is the goal of the project to keep access available at all times for those residents and businesses that take direct access off of the project streets but the road surface will be gravel during most of the project. During some of the underground storm sewer work, short term closures of a block long portion of the street during the day may be needed. There may be short term delays for access to or from your driveway or on the road where you may have to wait for the construction equipment to pass by. During curb and gutter installation and driveway apron replacement, there will be a period of days where residents will not be able to access their driveways and all parking must be done on the street. Residents will receive notification prior to any driveway closures. The project is anticipated to take approximately four months to complete.
