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 cross section, 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, actually considered improvements between Mill Valley Road and Decatur Street.

Project Goals:
- Improve grades and intersection sight distances
- Reduce crashes
- Improve bicycle and pedestrian accommodations
- Improve access and drainage
How Decisions Were Made
Multiple criteria evaluated:
- Safety
- Traffic flow
- Pedestrian / bicycle compatibility
- Minimize property impacts
- Adjacent projects
- Multiple stakeholder meetings and public comments
108th Street Preferred Alternative
Future vision for 108th Street.
Click on the Image to begin playing the video. If you would like to pause the video at any time, please hover over the bottom of the video window and click on the pause button.The preferred alternative is a three-lane section—one through lane in each direction with a center turn lane—through most of the corridor.
The preferred alternative also includes roundabouts located at Mill Valley Road, Burt Street and North Mill Road intersections. A new 10-foot-wide trail is located to the east and new sidewalks will be built on the west side of 108th Street, connecting to Horizon and Lee Valley parks. Three new protected pedestrian crossings will be located generally between Nicholas Street and Franklin Street. Multiple bus stops, intersection lighting and new storm sewer will be located throughout the project area.

108th Street Construction Phasing
In general, construction of the project would begin on the south end and continue north. The extent, duration and timing of each phase will be developed during final design and shared prior to the beginning of construction.

Oakbrook Channel Project Overview
Click image to enlarge
The Oakbrook Channel Outfall Repair focusses on the main channel downstream of, and including, the recently completed Phase I Project, and the tributary channel perpendicular to 108th Street near Charles Street. Channel instability has the potential to impact adjacent public and private infrastructure resulting from continued channel degradation, channel widening, and channel migration.
Project Issues:
- Channel degradation
- Channel widening
- Migration near power lines
- Storm sewer outfalls compromised
Stabilization and restoration measures are needed to mitigate the remaining unstabilized portion of the Oakbrook Channel. The goal is to improve channel stability, mitigate storm drain outfall erosion, all while coordinating with the 108th Street Project.
Project Goals:
- Rehabilitate and restore the stream channel
- Protect adjacent infrastructure
- Develop implementation plan
- Coordinate with 108th Street Project
Oakbrook Channel Schedule
Oakbrook Channel Alternatives
- Alternative A
- Alternative B
- Alternative C
- Alternatives D and E
Alternative A incorporates a low bed profile (near existing bed profile elevations) and reduces the need for cross vanes except in the Oakbrook Upper Reach. In the Upper Reach, four sets of cross vanes (3-4 cross vanes each) would accommodate the change in bed profile. Channel geometry would be modified to accomplish a stable slope.
Access to intermediate features would be difficult due to overall top width, proximity of nearby features, and property ownership. Access limitations would be similar to the existing condition. Sanitary sewer infrastructure along the south side of the Tributary Channel would need to be relocated or protected.

| Alternative A | |
|---|---|
| OPPD TRANSMISSION LINE | Realign stream and adjust side slope near this feature |
| OAKBROOK PARK | Realign stream and adjust side slope near this feature |
| SANITARY SEWER LINE | Relocation or protection required |
| ADJACENT PROPERTY | Structural measure required to maintain clearances for apartment building |
| CHARLES ST. OUTFALL | Remains in place |
