Tree Top Lane Sidewalk

In 2024, the City started design on new pedestrian improvements along Tree Top Lane, from Overlook Drive to Fernwood Drive. Throughout the design process, the City gathered community input through open houses, one-on-one meetings, and surveys to inform the final designs.

Shaped by feedback from the community, available roadway space, and technical analysis, designs were completed in spring 2025. 

Final Design Details

The recommended Tree Top Lane design expands pedestrian comfort and safety with a 6.0-foot wide sidewalk built from the current curb out away from existing properties between Overlook Drive and Fernwood Drive. Constructing the sidewalk “curb out” within the existing roadway preserves trees and minimizes impacts to driveways, utilities and stormwater management, significantly reducing project costs and construction timeline. The road will be re-striped to only allow vehicle parking along the east side of the roadway adjacent to the new sidewalk.

Improvements at a glance:

• Preservation of existing trees
• 1,300 feet of new concrete sidewalk
• Five new or improved ADA-compliant curb ramps
• Four new or improved crossings at Overlook Drive, Tree Top Way, and Fernwood Drive

*Feedback referenced represents the preferences of neighbors who shared their input during the design process.

Project Updates

Thursday, November 13, 2025

Major construction is complete on the new sidewalk, however, some outstanding items remain and will need to take place in spring 2026 due to the weather (temperature and rain). These items include:

• Permanent striping of the Overlook/Tree Top crosswalks.
• Fixing the yellow centerline stripe on Tree Top Lane.
• Permanent striping of the new speed bumps.

In the meantime, the contractor will be installing some temporary striping/stick and stomps to help identify the speed bumps on Tree Top. They will also be removing any remaining equipment from the site until they return in the spring.

Friday, September 19, 2025

The contractor has indicated they will be working on the speed bumps along Tree Top next week and have requested no parking ON the Tree Top speed bumps Monday-Friday. They will put up no parking signs in the areas needed near the speed bumps.

The remaining clean up and punchlist work, including the landscaping restoration and permanent striping on Tree Top is scheduled for Friday, October 10, when school is out for the day. Their landscapers will need access so they’ll be putting out no parking signs for that day.

Tuesday, August 26, 2025

• For residents on the sidewalk side, your mailbox will be permanently reinstalled this Friday with new posts!
• On Friday, crews will also remove the stripe in the middle of the street, place temporary striping/stick and stomps for the new center lane, and install no parking signs on the west side of Tree Top Lane. These will be temporary until the permanent signs can get installed next month and the permanent striping will also be scheduled for next month.
• Parking will only be allowed on the sidewalk side as we want people to park, get out of their vehicles and use the sidewalk, and not have to cross two lanes of traffic to get to the pedestrian facility. This is the same design that occurred for the new sidewalk on Boca Ratan Drive, in the Forest Hills neighborhood.
• A landscape company will be scheduled in the coming weeks to backfill the backside of the sidewalks and do cleanup work, including adjusting sprinklers etc.
• Unfortunately, there is still work taking place on Overlook. Due to unforeseen utility issues and PGE delays, we may have to finish some of the sidewalk, utility reconnections, and final paving in that area when school is back in session. Work hours and any impacts to traffic on Overlook will be limited to 9 am to 3 pm to minimize interruptions to school traffic.

Tuesday, August 12, 2025

Crews are making solid progress with the new sidewalk on Tree Top, and should be finished pouring the bulk of the concrete today.

This Thursday, 8/14 crews will be paving the sawcut portion of the roadway between the new sidewalk and existing asphalt on Tree Top. Access to everyone’s driveways should be restored by Friday 8/15 after the paving is complete and the driveway concrete has finished curing!

This Thursday and Friday, crews will also be demolishing the south side of Overlook between Meadowlark and the church. Next week they will begin forming the curbs, gutter and sidewalk, followed by concrete pouring mid-next week.

Tree Top is expected to be back open to two-way traffic early next week. 

Tuesday, August 5, 2025

Crews are making great progress with the new sidewalk on Tree Top Lane, from Overlook Drive to Fernwood Drive! Last week curbs were poured all the way from Overlook to Fernwood. 

Tomorrow, crews plan to pour the driveway aprons along Tree Top Lane, and next week pour the new sidewalks! In addition, next week crews also plan on forming and pouring the new sidewalk and curbs along Overlook Drive, between Meadowlark and the church. 

Tree Top Lane is currently one-way northbound only, between Overlook Drive and Tree Top Way during the sidewalk construction work. A detour is in place on Tree Top Way. This is expected to be in place through August 18. 

Monday, July 14, 2025

This week, crews are mobilizing their equipment, setting up erosion control and tree protection fencing, surveying, and sawcutting the asphalt on Overlook and Tree Top.

The contractor does intend to focus their major sidewalk work over the next month or so on the missing sidewalk segment on Overlook (between Tree Top intersection and the church), the curb ramps at the intersection, and also the sidewalk on the upper section of Tree Top (between the Overlook intersection and reservoir site). Major excavation and prep work for these new curb ramps and sidewalks is expected to start the week of July 21. The goal is to have these two segments completed in time for when school resumes.

Trees that are permitted for removal on Overlook and Meadowlark should be removed in the next couple weeks, please watch for lane closures and tree removal specialists as this work takes place.

Major construction work on the remainder of Tree Top (lower section) and Meadowlark is expected to take place in September. However, schedules are subject to change.

Please watch for lane closures /and or flaggers. Access will remain open for residents, emergency services, mail, and garbage collection. The project team will coordinate any driveway reconstructions or mailbox relocations with impacted residents in advance.

Thursday, July 3, 2025: Construction Starting in Mid-July

On Tuesday, July 1, City Council approved a public improvement contract with Turney Excavating Inc. for construction of the new sidewalks on Meadowlark and Tree Top. 

Residents may have noticed crews in the project limits today, marking utilities along the pavement, driveways and work areas with paint. These paint marks will come off over time. Turney is indicating they would like to start with preliminary work as early as late next week, including setting up their equipment, erosion control, and tree protection fencing. This could be followed by some tree removal along Overlook and Meadowlark.

Once we meet with the contractor early next week we will share more of an update on work schedule, but they are likely to focus their first phase along Overlook Drive and the upper section of Tree Top, with a goal of completing these sections before school resumes.

What to expect during construction:

• Work hours are 7 am – 6 pm, Monday to Friday. Some Saturday work may take place 8 am – 6 pm.
• Expect lane closures or flaggers during work hours with traffic shifted. Any road closures will be posted in advance.
• Access will remain open to residents within the work zones, emergency services, mail, and garbage collection.
• During work hours, expect brief delays, dust, vibration, and noise from activities and equipment.
• Underground utilities will be marked on the street and in the right-of-way with paint. Wooden stakes may also be placed in some areas within the project area.
• Some trees that have been permitted for removal will be removed at the beginning of the work.
• Steel plates may be placed, and equipment will be stored on the street or in the right-of-way.
• On-street parking may be restricted at times in the work zone.
• The project team will coordinate any driveway reconstructions or mailbox relocations with impacted residents in advance.

Schedules are subject to change.

February 2024: Preliminary Work Starting Soon!

In the coming weeks, underground utilities will be marked in the City’s right-of-way so the design team can begin with their initial survey and geotechnical investigation efforts. Crews may be taking photos, surveying the area for elevation and locations of utilities, mapping and accessing the health of trees, undertaking geotechnical investigations, and gathering other information to inform the early stages of design work and future construction. Most of the preliminary work is expected to take a few weeks to complete, although some follow-up visits throughout 2024 may be needed.

Neighbors may notice the following:

• Survey crews will be conducting field work predominantly in the public right-of-way, but at times, may need to access private properties to verify property corners and monument markers. Our survey consultant will mail out right-of-entry letters to all affected property owners.
• A few intermittent lane closures may occur during the daytime while crews conduct exploratory drilling and surveying. Flaggers or signage will direct drivers or assist local neighbors with access.
• Trees may be flagged during survey work. We will be looking at how to minimize impact to trees and will have an arborist working with the team.
• Underground utilities will be marked on the street with paint. Paint marks will disappear over time.
• Wooden stakes with flags might be left at some places along the project area. These may indicate the public right-of-way, drainage issues, or other considerations. Please do not remove or adjust the stakes.
