Burlington Greenway: Bike Path Rehabilitation Project

2016-Phase1b-Map-SM

CLOSURES & DETOURS

  • Beginning Tuesday, September 6, there will be limited access from the Skatepark to North Beach as contractors prepare for full shutdown

  • On September 12, 2016 at 7am the path will close to ALL traffic from the Skatepark to North Beach

Details: The Burlington Bike Path will be closed to all traffic from just north of the Skatepark to North Beach beginning Monday, September 12, 2016 at 7am. Closure will remain in effect through the fall construction period, and may reopen in November.

Additionally, access to Texaco Beach will be closed from the south (still accessible via North Beach) and there will be NO ACCESS to the Bike Path from the former Burlington College property trails nor any other trail access between the Skate Park and North Beach. Plan your route accordingly.

Burlington Parks, Recreation & Waterfront was able to delay the closure from the scheduled date of September 4, thanks to cooperation from bike path contractor S.D. Ireland. BPRW acknowledges the inconvenience, reminds riders that full reconstruction does require full closures, and thanks users for their patience.

Detour: From the south, please detour using Depot St. to North Avenue and from the north, use Institute Road to North Avenue.

Burlington Greenway Just Got a LOT Greener!

Phase 1b of the Burlington Bike Path Rehabilitation is the largest public ‘depaving’ project the city has ever seen!

600 tons of asphalt and 800 tons concrete – relics from the waterfront’s industrial past – have been removed to date, with significantly more slated for removal later in the project. But it’s not only what we are taking away, it’s what we are adding… rich topsoil will take the place of formerly paved areas, which will support the growth of 126 new trees and 167 new woody shrubs, plus thousands of perennials. BPRW will also be managing the natural growth occurring on the site, fostering the establishment of countless naturally seeded species like red oak that have been discovered and protected during the construction project. Take away the paving, add good soil and vegetation, and you’re left with an ecologically improved site that is more capable of absorbing stormwater runoff, has a higher potential for sequestering carbon and reducing the urban heat island affect and is a richer environment for plants, animals and humans alike!

Less concrete, more clean topsoil!

RECENT PROGRESS

The Project Heads North While Building Out the South

The broken and undulating asphalt of the Texaco to North Beach sections of the path are no more ! Our contractor has completed the removal of the asphalt paving in this stretch and has evaluated the sub-base underneath. Guess what ? There’s very little of it, and in some cases none. As you recall, it’s all about the sub-base, the substantial layer of compacted gravel that underlies all paving, providing a stable, well-drained foundation for hard surfaces.  The new bike path will have a new sub-base that will help to lengthen the lifespan of the path.

Asphalt is removed from the old path in the area just south of North Beach, revealing very little or no gravel sub base.

Work on the drainage course and railroad era stone culvert continues in the area between North Beach Campground and Lakeview Cemetery. Stone armoring in the ravine to the east of the path has been completed, and 8’ of silt removed from the entrance to the culvert. While that area dries out, our contractor has turned their attention to the lake side, and is making repairs to the headwall of the culvert’s outfall and reinforcing the stone armoring of this slope. We are using a combination of plant material and stone to ‘bioengineer’ this slope, making it more resilient to the ravaging affects of high water and wave action. Additionally, we are doing work to intercept and slow stormwater upstream.

The outfall of the North Beach stone culvert has partially collapsed and will be repaired in conjunction with bike path rehabilitation.

Pause Places 2 & 3 continue to come together !  The forms of the substantial foundation that will serve as the base for beautiful stone steps and sitting blocks leading from the edge of the bike path to the water’s edge have been removed and prepared for their stone finish. At Pause Place 3, our contractor has completed the concrete frost wall that forms the inside edge of the decked platform. Work is nearing completion on the stone reinforcement of the side slopes that allow proper grades for an ADA compliant walkway leading to Texaco Beach from Pause Place 3.

Full Closure Expands Work Area and Facilitates More Work In Less Time

With the path fully closed, our contractor is working on multiple fronts to complete the project as efficiently as possible. As the demolition and rip rap crews have moved to the north end of the project, concrete and carpentry crews have replaced them in the southern portion of the project. With foundation work on the deck overlook at Pause Place 3 nearing completion, framing should begin soon on this focal point of the new mini park. Two more exposed aggregate pads for exercise equipment and bike racks will be installed before the end of the month. Our contractor is aiming to begin paving portions of the bike path itself by the beginning of October. Work to repair the failing lakeshore slopes below Lakeview Cemetery should be completed in the same time period, along with engineering upstream to intercept stormwater coming off the cemetery.

Soils in the former railroad corridor along North Beach and the cemetery have been pre-characterized and will be hauled off site and properly disposed of. We have worked closely with our design engineer, soils consultant and the Vermont Department of Environmental Conservation to minimize excavation through this area to keep our costs low and disposal to a minimum.

Concrete work and the framing for the overlook deck at Pause Place 3 will continue in the middle section of the project and before the end of the month our landscape subcontractor will begin planting the 100’s of new trees and shrubs that will help restore the ecology of this site while providing a beautiful and resilient environment for the community to enjoy.

RECENT PROGRESS

Pause Place Progress, Shoreline and Stormwater Repair, Gearing Up for Shutdown

Finish materials are starting to be installed! Beginning with Pause Place 1 at the south end of the project. exposed aggregate concrete pads are being installed that will serve as the platforms for the new UVM Medical Center Fitness Stations, bike racks and benches. Just up the lakeshore at Pause Place 2, the forms are coming off the subtantial foundation that will serve as the base for beautiful stone steps and sitting blocks leading from the edge of the bike path to the water’s edge. Finally, at Pause Place 3, the mini park at the former Texaco Beach, all of the helical anchors that will support the wood deck structure are in place, and our contractor has excavated for the frost wall that will form the inside edge of this platform. Work also began on the stone reinforcement of the side slopes that allow proper grades for an ADA compliant walkway leading to Texaco Beach from Pause Place 3.

Full Path Closure Starting Monday, 9/12/2016, Allows Our Contractor to Make Efficient Progress Through the Narrow Confines South of North Beach

As work continues on the drainage and slope failure near North Beach Campground, the full closure of the path between the Skate Park and North Beach allows our contractor to advance efficiently to the north removing old path pavement, evaluating the condition of the sub base underneath, and excavating for the new, wider path.  Just like the industrial past at the Urban Reserve, the railroad history through this tight corridor has left us with a legacy of various urban soil issues. Soils through this area have been pre-characterized and will be hauled off site and properly disposed of. We have worked closely with our design engineer, soils consultant and the Vermont Department of Environmental Conservation to minimize excavation through this area to keep our costs low and disposal to a minimum.

Thank you in advance for your patience as we close section 1B of the path for this next portion of the project. We know you’ll love the finished product and it will be well worth the short term inconvenience.

New Alignment Base Marches North, Pause Places Take Shape, and Helicals Get Driven
The substantial base — a sandwich of geotextile fabric, compacted coarse sand and gravel –is advancing northward towards Texaco Beach. It will eventually be hidden, but it’s crucial to the longevity of the path surface. From there it will rejoin the existing alignment as it heads towards North Beach. Along its western edge, three new pause places are taking shape. A massive concrete foundation, will soon support a beautiful set of granite steps and seating blocks leading down to the water’s edge adjacent to the dog park. Further to the north at pause place 3 (Texaco Beach), innovative helical pilings (like plastic drywall anchors but much, much bigger) will provide support to the deck overlook structure at the NW corner of this new mini park.  Using these helicals, as opposed to traditional concrete footings, allowed us to cause less disturbance to the soil, helping us preserve more trees, drastically reduced excavation of urban soils, and saved us money. Work also continued on excavation and filling of planting pits with nutrient rich topsoil/compost mix.
Check out this cool video of Helicals being installed. We’ve been watching it here in the Planning office!

Things Really Get Rolling as Next Stretch of Path Is Removed and Prepared for Widening and Paving

The next two weeks will see a substantial increase in activity and scope on Phase 1b. Crews will get started on framing the structure and installing the concrete knee wall that will support and provide the edge for the wood deck structure at the heart of pause place 3. Trees and shrubs will be planted in the Urban Reserve portion of the project, and work expands northward as the old path is removed from Texaco Beach to North Beach, and an area of slope failure and excessive sedimentation is repaired adjacent to Lakeview Cemetery. Remember to plan ahead for the closure of this entire section on September 12 beginning at 7am. We are sorry for the inconvenience and know you will appreciate the new and greatly improved path next season!

Update: 8/25

The elevated grade at Pause Place 3, the mini park that will be the heart of this stretch of the bike path, is nearly complete and the vision for this space is starting to take shape. To the south, Pause Place 2 is also coming together, with the concrete footing for the granite stairs and seating blocks that will provide access to the water at this spot, being poured earlier in the week.  Additionally, planting pits filled with nutrient rich topsoil/compost mix, are being prepared throughout the site.

2-Week Look Ahead:

Preparation of planting pits continues in anticipation of planting a portion of the woody trees in shrubs in September and October. Work will continue at Pause Place 2 in preparation for the installation of granite steps and seating blocks during the ideal low water conditions of autumn. With industrial piping now removed, installation of geotextile fabric, sand and gravel base material for the new bike path will continue towards Pause Place 3. Innovative helical foundation anchors, designed to support the deck overlook at Pause Place 3, will be augured into place at the beginning of September. Once the anchors are in place, S. D. Ireland will install a curved footing & frost wall to support the east side of the deck that abuts the new path at the oval. Additional construction crews will then be mobilized to construct the deck and install the railings.

Update: 8/18

Our contractor continues moving fill material to Pause Place 3 (Texaco Beach area), which is now approaching final grade. Underground stormwater infrastructure was installed, which will help transfer storm runoff without compromising the new bike path. Shoreline armoring throughout the project was completed, and importing of topsoil and compost is ongoing. Work has started on the installation of a concrete foundation for the stone steps and sitting blocks at Pause Place 2. Locations for new tree and shrub plantings have been finalized and staked, and our contractor will begin to excavate the planting pits in those areas and fill them with a mix of topsoil and compost. Additionally, SD Ireland completed repair of the access ramp between the Bike Path/Campground and the North Beach Access Road, removing rough asphalt paving and installing compacted gravel fines for a short term solution. The plan is to pave that path when the rest of the project gets paved in late fall 2016.

2-Week Look Ahead:
Establishing final grade at Pause Place 3 will continue, along with the installation of stone stair treads and sitting blocks, followed by a metal railing. The contractor will continue to push north with path sub base from the staging area towards Texaco Beach. Work will continue on removal of industrial remnants (concrete, asphalt, pipes) as progress continues on what may be the largest de-paving project in the city.

Overview: Bike Path Rehabilitation Project

The Burlington Bike Path is an 8-mile route from Queen City Park Road to the Winooski River, and it is Burlington’s most popular amenity.

  • It links six major waterfront parks along with the Burlington High School, central waterfront district and many other local attractions.
  • The bike path is essential for meeting alternative transportation goals, health and wellness of residents, and supports the tourism industry. It has an estimated 150,000 users annually.
  • The bike path was built 27 years ago and is not constructed to today’s standards.

The objective of this project is to rehabilitate the Burlington Bike Path to update it to current multi-use path standards to serve its ever increasing use, to increase resiliency, and to ensure it withstands the test of time to continue serving Burlington residents and visitors. The Bike Path Rehabilitation Project proposes the rehabilitation of the entire 8 mile path. This project will be a phased effort with full preliminary design for the entire length of the path that began in July of 2013. Phase 1 of the project consists of Phase 1a, encompassing the length of the path from Perkins Pier to Penny Lane, and Phase 1b, encompassing the length of the path from Penny Lane to North Beach. Phase 1a of the Burlington Bike Path Rehabilitation project was completed in 2015 and included improvements in alignment, signage and landscaping from Perkins Pier to Penny Lane. Phase 1b of the project began in June 2016 and will update and realign about one mile of the path from the Andy A_Dog Williams Skatepark to North Beach.

Estimated Phase 1b construction costs: $2.4M
Prime Contractor: S.D. Ireland
Owner: Burlington Parks, Recreation and Waterfront
Resident Engineer: EIV Technical Services
Designer: Vanasse Hengen Brustlin (VHB)

Funding Sources: Tax Increment Financing (TIF), Fiscal Year 2016 Capital Improvement Program resources, Penny for Parks funding, support from the Bike Path Maintenance and Improvement Fund, and private philanthropy from the Parks Foundation of Burlington.

 

The Burlington Bike Path Phase 1b project will include the construction of three new pause places.

The pause places will provide more recreational opportunities, including new fitness equipment provided by UVM Medical Center. Path rehabilitation through the Urban Reserve will have a new alignment that bringing users closer to the lake. The first two pause places will be located adjacent to the new dog park and create access to the lake, fitness equipment, bike racks, and wayfinding. The third pause place has been designed as
a “pocket-park” with a new deck providing views of both the lake and City, as well as ADA access to the beach. The completed project will improve accessibility, add bike racks, and include the planting of over 150 native and cultivated varieties of trees and shrubs. Vegetation improvements will provide shoreline stabilization, place-making and landscaping along the bike path.

Closures

Path users should expect brief closures of the path for the crossing of construction equipment. The dog park within the Urban Reserve and the Phase 1b construction site will be closed this summer. It will reopen in 2017 as a restored dog park with new fencing, gates, signage and improved water access. After Labor Day, the second part of construction from the Urban Reserve to just south of North Beach will require a full path closure. A detour through the North Beach Campground to North Avenue and down Depot St. is planned for path users. Access to the path by the Sailing Center and Skatepark will remain open.

Timeline

Construction of Phase 1b will last through this December 2016 with landscaping completed early in the spring of 2017
