Construction Update 5/22/18

There is a lot of activity taking place in the project area right now. Emery and Sons Construction Group (Emery) is now working on installing storm lines on 7th Street and D Avenue, and a water line on 1st Street. NW Natural is also working in multiple block segments on D Avenue to relocate their gas main.

Important Safety Reminders

Safety is by far our first priority. This is an important reminder to vehicular traffic, pedestrians, bicyclists and neighbors: please avoid accessing the active work zones and closed areas during work hours. Construction sites are busy places with lots of moving equipment, open trenches and deliveries of materials. Please use another side street or alley to get to your destination, and abide by the traffic control signage. This is to maintain the safety of all.

LOCAL ACCESS ONLY – What Does That Mean?

You are only considered “local” if you live on the street within the closed area and need to get into the immediate area, not through it. This includes residents who live on the closed street, emergency vehicles, visitors, babysitters, landscape workers, garbage and recycling vehicles or deliveries. Everyone else is considered “thru traffic” (including other neighborhood residents and traffic) and must take another route to get to their destination.

So that everyone stays safe, please obey the signage and allow extra time to get around the neighborhood. If people continue to cut-through the work zones, police will be conducting extra patrols.

Tree and Brush Removal Continues

Crews have started removing some trees, shrubs and brush located in the work zones. This work is now expected to continue for another two weeks. During this time, crews will also trim tree branches that are overhanging into the right-of-way in areas where the contractor needs additional clearance.

NW Natural Gas Relocation

NW Natural Gas is now working on relocating their gas main on D Avenue between 1st and 3rd Streets. This relocation has been slower than originally anticipated. As a result, Emery continues to shift their work plan, as most of NW Natural’s relocation work needs to be completed before the major road reconstruction work can take place along D Avenue.

We continue to coordinate with NW Natural. For concerns or questions regarding this work, including potential temporary gas service shut-offs, please contact Rich Girard on 503-226-4211 or r2g@nwnatural.com.

Major Utility Work Progressing

Last night, Crew 1 finished installing the storm line on 1st Street between D and E Avenues (pictured below). The intersection at E Avenue and 1st Street is now back open, but 1st Street will remain closed between D and E Avenues as a third crew will be working to install the water line. This work is expected to continue for another two weeks.

There will be some minor anticipated water service interruptions (temporary shut-offs for 1 hour approx.). These will take place on 1st Street when crews switch over the water services to the new line. Impacted neighbors will be notified in advance via a door hanger.

Today, Crew 1 is moving to the corner of 7th Street and B Avenue to begin installing the storm line on 7th. The intersection at B and 7th remains open, but the road is closed on 7th Street between B and C Avenues. This work will progress north towards D Avenue over the next few weeks.

Crew 2 is making good progress installing the storm line on D Avenue. They moved across the intersection of 5th Street yesterday, and are now working between 5th and 6th Streets. This one block is closed to through traffic during work hours. Crew 2 expects to be at the intersection of D Avenue and 7th Street by the end of next week, and will continue working west towards 10th through mid-June with rolling temporary road closures.

For more information about the overall work plan, visit our project schedule page.

General Information

Allowed work hours are 7 a.m. – 6 p.m. Monday to Friday. In observance of Memorial Day, there will be no work on Monday, May 28.

With all the work taking place in the neighborhood, please be alert, drive safely, choose another route or plan ahead for travel delays.

As noted, construction schedules change frequently. We will strive to keep residents informed through these regular updates.

Construction Update 5/8/18

Preliminary Work Continues

Emery and Sons Construction Group (Emery) crews have started mobilizing equipment and installing tree protection fencing (shown below) in the right-of-way throughout the project area. This will continue over the next day or so.

Tree protection fencing is required by city code to be installed around trees that are 5-inches or larger in diameter.

Also this week, erosion control and work zone fencing will be installed throughout the work zone on D. These measures will help prevent sediment from washing off the project and clearly delineate the active work area (or “extent of work”) that is expected to be disturbed during construction. Crews will also be installing a 40 ft. long construction trailer at the reservoir site on the corner of C Avenue and 10th Street.

No excavation work or tree removal work can begin until all of the tree protection and erosion control measures are in place, inspected and approved.

Starting tomorrow, Wednesday, May 8, crews expect to begin removing the 49 trees located in the right-of-way which are permitted for removal. Trees will be chipped on-site using a large chipper truck, and hauled off-site for recycling and reuse. Neighbors should expect to see and hear a large chipper truck and crews using chainsaws. Temporary block closures will be in place as crews move through the corridor along D.

The tree removal work is expected to last about two weeks. During this time, crews will also trim tree branches that are overhanging into the right-of-way in areas where the contractor needs additional clearance.

Smaller shrubs and landscaping that is slated for removal and located within the active work area on D will also be cleared and removed. Please note, in March, letters were sent to every property owner along D outlining the extent of work and notifying owners to relocate or move any landscaping or improvements before construction starts.

In preparation for the major utility work, crews will also begin saw-cutting parts of the roadway in the project area.

NW Natural Gas Relocation Continues

NW Natural’s gas relocation work has been progressing slower than originally anticipated. As a result, Emery is now having to shift their work plan, as most of NW Natural’s relocation work needs to be completed before a lot of the major City work to take place along D Avenue.

We continue to coordinate with NW Natural. For concerns or questions regarding this work, including potential temporary gas service shut-offs, please contact Rich Girard on 503-226-4211 or r2g@nwnatural.com.

Emergency Water line Repair Postponed

After uncovering all existing utilities in the intersection at D Avenue and 8th Street city crews discovered that the existing storm line is located closer to the connection point of the water line that needs to be repaired. This means they will have to postpone the repair until after the new storm line is installed and the old storm line is removed from service.

Major Utility Work Starts May 14

Emery plans to have two main crews working throughout the project duration, now starting on Monday, May 14.

The first crew is set to begin on 1st Street at the intersection of D, installing a new storm line and manholes at the intersection then new water and storm pipes up the length of 1st Street to E Avenue.   This work is expected to take about three-four weeks to complete.

While crews are working in the intersection, D Avenue will be closed to through traffic between State Street and 2nd Street and 1st Street will be closed between C Avenue and E Avenue. Once crews progress through the intersection, D Avenue will be reopened at State Street.

There will be some minor anticipated water service interruptions (temporary shut-offs for 1 hour approx.). These will take place on 1st Street when crews switch over the water services to the new line. Impacted neighbors will be notified in advance via a door hanger.

The second crew is set to begin at 4th and D (near the library), installing a new storm line and manholes, and then working towards 5th. Work in this area is expected to take about a week, then crew 2 will likely shift to 7th Street (at B), to install a new storm line. This is dependent on NW Natural’s progress.

During the work near the library, please watch for signage and flaggers to safely navigate through the intersection. D Avenue will be closed to through traffic between 4th and 5th Street. There will also be no on-street parking allowed.

Overall Work Plan (*subject to change!)

The estimated duration for Emery’s underground utility work is about 6 weeks, however, this is subject to NW Natural’s progress. Daily road closures will be in place in the work zones during the majority of the big pipe work. Roads will be open after work hours during the utility work.

Once all the underground utility work is done, the major road reconstruction work will begin and this will result in full (24/7) rolling road closures. For this work, crews expect to start on D Avenue at 1st Street and work west to 10th, then loop back to do the block between State and 1st.

During the major road work, one crew will excavate the road/existing asphalt, rock it back, then move up to the next segment. Concrete crews would then arrive to form the sidewalks/valley gutters/curbs, and move onto the next segment. The next activity would be constructing the stormwater planters, then paving (likely late August). The final activity would be planting the final landscaping and installing the lighting (in the fall).

Full road closures will be needed along D Avenue in order for crews to conduct the work in a phased approach. Emery expects the full closures to be in place for 6 – 8 weeks (possibly starting in mid-late June). During this period, the contractor will maintain north/south access through the intersections of D Avenue at 1st, 4th, 7th and 10th (refer to road closure map below).  The work in the intersections will require flagged traffic at that time.

Residents located in the closure zones will be notified in advance of the full road closures via a door hanger, along with the email updates and website posts.

Construction Update

Gas Relocation

NW Natural’s gas relocation work continues along D Avenue. For concerns or questions regarding this work, please contact Rich Girard on 503-226-4211 or r2g@nwnatural.com.

NW Natural digging a trench to relocate their gasline.

Emergency Waterline Repair

While NW Natural’s crews were recently working through the D Avenue and 8th Street intersection, they discovered an old, cracked 2” water pipe. City crews will begin repairing this portion of pipe in the next week. This will require a full closure of the intersection at 8th Street and D Avenue, during work hours. Access will be maintained for residents that live in the closed area.

Upcoming Preliminary Work

Starting this week, surveyors will begin staking the right-of-way and preparing the project area for major construction.

During the week of April 30, crews will begin bringing in equipment, setting up erosion control and tree protection fencing, trimming tree branches and removing 49 trees located in the right-of-way, which are permitted for removal. Trees will be chipped on-site using a large chipper truck, and hauled off-site for recycling and reuse. Neighbors should expect to see and hear a large chipper truck and crews using chainsaws. Temporary block closures will be in place as crews move through the corridor along D.

Starting the week of May 7, crews expect to begin the major utility work. One crew will begin installing a new waterline on 1st Street, between E and D, and a second crew will begin installing a new stormline in the project area (exact starting location will be determined closer to the date as work needs to be coordinated with NW Natural’s gas relocation and the City’s waterline repair).

Know Before You Go

With the gas relocation work continuing on D Avenue, the water line repair work and our main contractor starting soon, there will be a lot of construction activity taking place in the project area and neighborhood. Crews will be overlapping, but all work will be coordinated.

During work hours, temporary road closures will be in place in the blocks where crews are working. No through traffic will be allowed during work hours in these active work areas, access is only permitted for local residents.

Please be alert, drive safely and plan ahead for travel delays.

Work hours are 7 a.m. – 6 p.m., Monday to Friday.

Please note, construction schedules change frequently. We will strive to keep residents informed through these regular updates.

We appreciate your patience and understanding with the construction.

505 G Avenue, Lake Oswego

There will be a brief presentation at the beginning of the meeting, followed by a question and answer session and an opportunity to meet the project team. We hope to see you there!

Construction

Unfortunately, construction will be disruptive, especially to those nearest the work. The project includes stormwater and waterline installation, roadway demolition, roadway surface preparation and grading, concrete formwork, concrete placement, concrete curing, asphalt paving and significant landscape and irrigation work. This means crews will be in front of each property – particularly along D Avenue – many times over the project duration.

There will be intermittent lane closures, and at times, there will be full road closures. We appreciate all neighbors abiding by traffic control signage and avoiding active construction areas for the safety of all. If you have a special access need we should be aware of, please contact the project us.

For more information about the project details and what to expect during construction, please review the latest newsletter or contact the project team.

Gas Line Relocation Work Starting this Week

Before the City’s main contractor (Emery and Sons Construction Group) starts work later this month, NW Natural will be working in the right-of-way along D Avenue, between State Street and 10th Street, to relocate a gas line. This is to avoid conflicts with the planned project improvements.

NW Natural is expected to start assembling equipment tomorrow, Tuesday April 10, with work beginning on Wednesday or Thursday. While Emery and Sons Construction Group does not anticipate starting work until the first week of May, there may be times where their crews and the NW Natural crew are overlapping in the project area. All work will be coordinated.

Work hours are Monday to Friday, 7 a.m. – 6 p.m. Neighbors should expect to see a small excavator for digging and a drill-rig that will be used to install the new gas line. Lane closures will be in place – please watch for signage and follow flagger directions. No full road closures are planned at this time for the relocation work. Utility contractors will notify residents of any planned temporary service shutdowns.

For more information about the gas line relocation work, please contact Rich Girard at NW Natural on 503-226-4211 or r2g@nwnatural.com

Save the Date: Thursday, April 26 Meet the Contractor Meeting

Last month, Council awarded a public improvement contract to Emery and Sons Construction Group (Emery and Sons) for construction of the D Avenue Improvement Project. Crews expect to mobilize into the project area and start work the first week of May.

A Meet the Contractor Meeting will be held on Thursday, April 26 at the Adult Community Center. We hope you can join us to meet representatives from Emery and Sons and learn more about upcoming construction in your neighborhood.  Stay tuned for more meeting details!

 

 

Design is Complete!

The City and project team recently completed design for the project. We encourage you to view the plans: read more about the final details, view the site plan map of the entire corridor (and the corresponding map legend), or download the detailed drawings for the project.

The project will reconstruct the entire ten blocks of D Avenue from State Street to 10th Street, all within the existing public right-of-way. Additional improvements will also take place on portions of 1st Street, 7th Street, 8th Street, 9th Street and E Avenue.

The design incorporates a much safer way for pedestrians to connect to schools, downtown businesses, the library and other services in the neighborhood. It also helps address significant stormwater issues and rebuilds old, deteriorated underground utilities in this area of the neighborhood.

Sample Cross-Section Rendering of the Final Design

Project Details

The City and project team has worked diligently to include neighbors and stakeholders in the design development and respond to requests or concerns. Two neighbor walking tours, two public open houses, numerous face-to-face meetings and extensive field work helped inform the designs of the project. Many neighbors are excited about the rain gardens, landscaping, sidewalk and overall roadway design.

Thank you to all the neighbors who have participated, shared your thoughts, concerns and ideas on improvements for the project. We appreciate your willingness to be involved and have enjoyed working with each of you to develop the design.

When construction is complete, the road and corridor along D Avenue will look different – the lanes for vehicles will be about the same width, but will have been shifted. Portions of the road alignment will meander with slight curves to allow for a new sidewalk and about 40 rain garden areas necessary to manage and treat stormwater. Parking areas will also be more clearly delineated within the public right-of way.

Sample Cross-Section Rendering of the Final Design

D Avenue Property Owners

If you are a property owner along D Avenue, please watch for a letter arriving in the coming days with information on the final design, a map of the improvements specific to the block on D Avenue where your property is located, and a factsheet about construction.

Meet the Contractor Meeting

With design now complete, the next phase will be construction. A “Meet the Contractor” meeting to introduce the contractor and share information about construction will be scheduled in the next month or so, before work begins. Stay tuned for more information on the meeting date and time.

Construction

Major construction is set to begin this spring and take about a year or so to complete. Most of the intensive construction is expected to occur in summer 2018. Schedules are subject to change.

Unfortunately, construction will be disruptive, especially to those nearest the work. The project includes stormwater and waterline installation, roadway demolition, roadway surface preparation and grading, concrete formwork, concrete placement, concrete curing, asphalt paving and significant landscape and irrigation work. This means crews will be in front of each property along D Avenue many times over the project duration.

There will be intermittent lane closures, and at times, there will be full road closures. We appreciate all neighbors abiding by traffic control signage and avoiding active construction areas for the safety of all. If you have a special access need we should be aware of, please contact us.

We will strive to keep neighbors aware of the ever-changing construction activities through our regular project updates. For more information about what to expect during construction, review the latest newsletter or contact the project team.

Utility relocations along D Avenue

Major construction is set to begin this spring for the D Avenue Improvement Project in the First Addition Neighborhood.

Before the City’s main contractor starts work, several private franchise utility relocations will take place in the right-of-way along D Avenue, between State Street and 10th Street. This work will involve some relocations of gas lines (NW Natural), power poles (PGE) and communication lines (Centurylink) in areas where they conflict with the planned project improvements or need to upgrade their systems prior to the City’s improvement project. Lane closures will be in place – please watch for signage and follow flagger directions. Utility contractors will notify residents of any planned temporary service shutdowns.

More information about the final design plans and construction will be shared in the next few weeks – stay tuned for another email update shortly!

For more information, please contact the project team.

Tree Removal Application for D Avenue

With final design wrapping up, the project team is preparing to submit a tree removal application. Starting tomorrow, neighbors may notice trees being flagged in the right-of-way along D Avenue and signage posted along the corridor (similar to the sign pictured herein)

.

The project design team put forth a great effort in juggling all competing interests, to minimize tree removal and avoid impacts to trees in the corridor. A total of 49 trees have been identified for removal as a result of the final design. Of those, 27 trees will fall under a Type II Tree Removal Application and are required to be flagged in yellow. The remaining 22 are on the City’s invasive species list and will fall under an Invasive Tree Species Removal Application. While the 22 invasive trees are not required to be flagged as part of the application process, these trees will still be flagged in pink.  All trees that have been identified for removal are located within the public right-of-way and mitigation measures will include the planting of 74 replacement trees.

The project team has prepared a comprehensive Tree Protection Plan that spells out what protective measures will need to be taken when the project is under construction.  Measures include a contractor tree protection meeting, tree protection fencing and signage, and identifies specific trees that will require monitoring by the arborist when work is occurring within critical root zones.

Approved trees will not be removed until a contractor is on board this spring.

Final Design Plans

The final plans will be posted on the materials page in the coming weeks. We’ll send an email update once they are posted online. In the next month, letters will be sent to property owners on D Avenue to share the final design related to their frontage.

Construction and ‘Meet the Contractor’ Meeting

Construction is expected to begin this spring, with varying activities taking place throughout the corridor into late fall 2018. Depending on weather and other variables, the final paving and plantings could shift to spring 2019.

Once a contractor is on board, the project team plans to hold a ‘Meet the Contractor’ meeting to share more information about construction, duration, expected impacts and provide an opportunity for neighbors to meet the contractor before work starts in the neighborhood. Stay tuned for a meeting announcement shortly.

For more information, please contact the project team.

Another Informative Open House

On Thursday, October 26, the City and project team held the second public Open House for the project. About 55 people attended the event, providing feedback and comments on the 60% design details for the stormwater, pedestrian and pavement improvements on D Avenue.

The open house included information and graphics on the location of improvements (road, sidewalk, parking, stormwater features) within the right-of-way, landscaping, stormwater management, and general construction issues and schedule.

Thank you to everyone who attended. We appreciate your enthusiasm and participation in the project, and for sharing your thoughts about the current designs for D Avenue.

A meeting summary is available here. If you who were unable to attend the open house, the displays, graphics and boards presented are available on the materials page of the website. Please note, these are not final designs – these are the 60% level.

Using the latest feedback, comments and some additional field information, the project team is now refining the design details. 90% designs are expected to be complete in the next month.

Construction is expected to begin in spring 2018, with varying activities taking place throughout the corridor into late fall 2018. Depending on weather and other variables, the final paving and plantings could shift to spring 2019. Preliminary information about construction, duration and expected impacts is outlined here. More construction information will be shared in the coming months, as the design is finalized.

Next week, on November 7, the project team will be providing an update to City Council.

For more information, please contact the project team.

Brief Lane Closures on D Avenue: Nov. 7 – Nov. 10

Starting on Tuesday, November 7, crews will be conducting exploratory digging (potholing for utilities) along D Avenue, between State Street and 10th Street. This is to help with finalizing design details for the project. Work hours are 7 a.m. – 6 p.m., Monday through Friday. This work is expected to be complete by Friday, November 10.

Brief lane closures will be in place during work hours, as crews work their way along D Avenue. Please watch for flaggers or signage to help direct you around the work zones.
