108th Street Project Overview
108th Street between Burt and Decatur has multiple driveways and is steep in some locations. The proposed project would improve safety, drainage and pedestrian connectivity issues by constructing a new roadway crosssection, storm sewer improvements and ADA-compliant ramps, trail and sidewalks in the area.
The 108th Street improvement project, while described as being between Burt Street on the south and Decatur Street on the north, may consider improvements between Mill Valley Road and Decatur Street.
The purpose of this project is to enhance safety for all modes of travel with the primary goals listed below.
Enhance grades and intersection sight distances
Reduce crashes
Enhance bicycle and pedestrian accommodations
Enhance access and drainage
Roadway Alternative #1

The first alternative would reconstruct 108th Street as a 2-lane roadway with curb and gutter. New sidewalk and multi-use trail would be constructed as well. These improvements would fit inside of existing right-of-way but may require some grading into private property.
Roadway Alternative #2

The second alternative would reconstruct 108th Street as a 3-lane roadway with curb and gutter. Again, new sidewalk and multi-use trail would be constructed as well. These improvements would also fit inside of existing right-of-way but would require some grading into private property.
A third alternative, not shown, would include a combination of the 2-lane and 3-lane alternatives in different locations along the corridor, based on traffic operations and safety considerations.
Roadway Cross-Section Evaluation
All three alternatives were evaluated based on the criteria shown on the screen. A full circle means the alternative best met the criteria, whereas an empty circle means the alternative was rated fair. This type of analysis is used to determine the alternative that most appropriately meets the project goals. Note that public and stakeholder input are one of the screening criteria considered in the decision-making process. Your feedback is needed and will be incorporated into this Evaluation Matrix for the final evaluation.
Alternatives Screening Summary - Corridor Cross-Section
Intersection Alternatives
Intersection control is another consideration for this project. Two intersection types are discussed below.
Roundabout Intersection
A roundabout could be constructed at this intersection, and potentially at other intersections in the corridor, calming traffic through the area, enhancing bicycle and pedestrian crossings, and enhancing overall safety for the intersection.
Traditional Intersection
The Burt Street intersection could be reconstructed to improve traffic operations and safety. Shown here is a traditional two-way stop-controlled intersection, where 108th Street/Avenue is the through movement.
Intersection Evaluation
Research shows that roundabouts provide a 35% reduction in total crashes and a reduced vehicle delay when compared to stop controlled and signalized intersections. Roundabouts also provide fewer pedestrian/vehicle conflict points. The safety and traffic flow of roundabouts are important to consider.

108th Street Project Schedule
We are currently in the preliminary design phase, with final design anticipated to begin fall of 2020, Right-of-Way anticipated to begin in 2021 and construction to occur in spring of 2022. Additional public meetings will be held during final design and prior to construction beginning.

Oakbrook Channel Repair Project Overview
The Oakbrook Channel has degraded over time, resulting in major streambank erosion and stability concerns. The area around the channel has been compromised, including sanitary sewer lines and power transmission line poles. There are also multiple private storm drain outfalls along the channel and the City is working with owners to develop solutions. The proposed project focuses on the downstream channel beginning near Seward Street and the tributary channel perpendicular to 108th Street near Charles Street.
The Oakbrook Channel Repair Project focuses on the main channel downstream of the recently completed Phase I Project, and the tributary channel perpendicular to 108th Street near Charles Street. Stabilization and restoration measures are needed to mitigate the remaining unstabilized portion of the Oakbrook Channel.
This project is being proposed to provide stabilization and restoration measures needed to mitigate severe erosion issues adjacent to 108th Street and Charles Street. This is a separate project, which could be constructed in conjunction with the 108th Street project, dependent on future funding.
The goal is to enhance channel stability, protect critical infrastructure, protect public and private property, and accommodate multi-use features for recreation, multi-modal transportation, and environmental benefit, where possible.
Oakbrook Channel Issues/Solutions
Severe degradation of the channel has prompted previous repair projects. However instability in the connecting channel sections still presents a threat to critical infrastructure, including public and private property as well as the function of the Oakbrook Channel system as a whole.
