Kettleby Road Reconstruction

From May 5th to May 7th (3 days), the contractor will be installing the asphalt splash strip on the South side of Kettleby Road.

Residents and visitors are asked to NOT park along the South side of the road during these days (i.e. along the curb when driving East toward Keele St.).

The Kettleby Road Reconstruction project is expected to resume on April 2nd (weather-dependent).

Residents can expect construction crews in the area daily to complete the road paving, driveway and landscaping works.

Important

A 1/2-day road closure is planned for April 8th at the Kettleby bridge to replace the existing guiderail. Detour and Road Closed signage will be displayed on Jane Street and Keele Street. Emergency services, mail delivery and waste collection staff have been notified.

The Township is requesting residents and visitors to Kettleby to avoid parking on the street from November 26th to November 29th

As part of the road reconstruction project, the rollover curbs will be installed this week. For the contractor to work as efficiently as possible, please refrain from parking on the street during these dates. (November 26, 27, 28, 29)

Street parking will continue to be available outside of the construction area (as currently permitted).

We apologize for the inconvenience and appreciate your cooperation.

Please be advised that Kettleby Road will be closed to through traffic on November 9th and 10th.

The Township uses best efforts to keep the road open during the weekends. However, due to unforeseen circumstances, the road must remain closed this weekend for safety purposes. Construction will resume on Monday November 11th.

The access points are:

• All properties West of (and including) #355 Kettleby Rd must use Jane Street
• All properties East of #355 Kettleby Rd must use Keele Street

We apologize for the inconvenience

The Township of King and the contractor for this project, Graham Bros. Construction, will be hosting a Meet-and-Greet for residents to ask questions and introduce staff from Graham Bros.

Details:

When: Thursday September 19, 2024 (7:00 pm to 8:30 pm)

Where: Christ Church Hall (292 Kettleby Rd)

Light refreshment and coffee will be served

Important

This is NOT an official Township event and is strictly for information purposes only. Residents are encouraged to attend, however, design or scope of work changes will not be considered. Residents are reminded to contact the Township for information throughout the course of this project.

In response to feedback from the community, the road design has been revised with minor change to the storm sewer, such that rollover curbs will be installed throughout the entire project on both sides of the road. While this is not the Township standard, consideration can be provided, given the historic character, narrow right-of-way and to accommodate the demand for street parking. The asphalt snow storage strip must remain to facilitate snow-clearing operations.

Other comments received:

Reinstate original road alignment

The change in road alignment is negligible. Minor shifting of the centerline was required to limit impacts to private property.

Ensure vibration tolerances are set at levels for stone and mortar foundations and dug well structures

As posted previously, the vibration criteria will follow the widely-adopted City of Toronto standard which includes lower tolerance for heritage properties.

Also reminder to residents to book a pre-condition survey with dBA Services.

Property owners within the project limits of the Kettleby Road Reconstruction can now book a pre-condition survey with the contractor's vibration specialist (dBA Services Inc.)

The full notice is in the Documents section on this page. This will also be hand-delivered to each property.

Important Information

Residents must book the pre-condition survey directly with dBA Services. If an appointment is not booked, NO SURVEY WILL BE DONE. If residents do not book a survey, it will be documented as such with the understanding that potential damage claims will likely be denied.

Please refer to the full notice for more details

The Work

King Township will be proceeding to reconstruct a 720 m segment of Kettleby Road between Kettleby Bridge on the west and the eastern limit of the community. The work will be completed by Graham Bros. Construction Limited. As part of the project, the Township is requiring that the contractor be responsible to retain a vibration engineer to monitor vibration during construction.

To help ensure that the contractor implements a proper vibration mitigation plan including vibration monitoring, King Township has retained HGC Engineering, a leading consulting engineering firm specializing in noise, vibration, and acoustics, to develop recommendations for the contractor to follow. See below for background information concerning construction vibration, an overview of typical criteria, and a summary of the monitoring plan.

Construction Vibration and Criteria

During road construction, vibrations can sometimes be felt by nearby residents. These vibrations, while typically minor, can raise concerns of potential effects on building structures. The sources of vibration during the project are most likely to be during the excavation of the current road surface and during the compaction of the granular roadbed.

Internationally recognized construction vibration guidelines have been in place for decades, most notably in European jurisdictions, where criteria have been developed to avoid cosmetic damage like cracking in structures. Locally, one of the most detailed documents that contains specific vibration criteria is the City of Toronto By-Law number 514, which has been informally adopted by many surrounding regions. Under this by-law, where a construction project will involve activity with a potential for vibration impact at off-site structures, a preliminary vibration assessment must be undertaken identifying a vibration Zone of Influence (ZOI), and a vibration monitoring plan must be developed. The by-law also requires supplementary preconstruction condition surveys of surrounding structures that are in the ZOI.

For vibration affecting structures, the use of peak particle velocity in units of millimeters per second (mm/s) is most common, with the vibration frequency described in units of cycles-per-second or Hertz (Hz).

The specific vibration criteria applicable at neighbouring structures, stated as the Prohibited Construction Vibrations in the by-law are shown in the table below.

City of Toronto By-Law “Prohibited Construction Vibrations”

Two additional points are worth mentioning. First, it is common for more stringent criteria to be applicable at sensitive or heritage-listed buildings. Second, cautionary vibration limits are recommended for use in monitoring, which include a factor of safety, beyond which greater care should be taken in proceeding with construction activities to help ensure that the prohibited vibration levels are not exceeded.

Vibration Monitoring

1. The potential vibration Zone of Influence (ZOI) for excavation and compaction activities on the Kettleby Road Reconstruction project is predicted to extend up to 12 meters from the perimeter of the road reconstruction. As such, several properties along the perimeter of the project are at least partially located in the vibration ZOI.
2. Three automated vibration monitors are to be installed, one at the closest building to the roadworks in each of three representative sections along the project corridor.
3. Automated vibration monitors will be fixed in place to the concrete foundation or slab, inside or on the exterior of the buildings at a point closest to the road construction.
4. The monitors will be equipped with wireless modems and configured to automatically notify site personnel and the municipality in the event of vibration exceeding 80% of the limits presented above (60% for heritage-listed buildings).
5. Vibratory compaction is to be minimized in areas adjacent to buildings, where practical, and should the cautionary vibration criteria be exceeded, lower energy settings, thinner lifts, and lighter equipment should be implemented as necessary.
6. Pre-construction condition surveys of buildings and structures located within the ZOI are also required and these are being arranged by the contractor.

IMPORTANT DATES:

Thursday August 29^th at 11:59 PM – Deadline to submit any questions or comments on the vibration monitoring background and process. Questions can be directed to Colin Parks – Project Manager (contact information below)

September 3^rd to September 13^th – Tentative window where the contractor will conduct pre-condition home surveys. Residents will be given a minimum of 48-72 hours notice to make an appointment with the consultants. These notices will be hand delivered to each property. The Township strongly encourages residents to partake in these surveys. If residents do not allow access to the home, it will be documented as such with the understanding that potential damage claims will likely be denied.

Hydro One has completed the majority of the tree trimming and digging holes for the new poles. Crews are expected to be in the area throughout July to install new hydro infrastructure (poles, transformers, anchors, support cables, etc.). Residents will be notified of planned power outages during these works.

To protect everyone’s health and safety, it is imperative that residents DO NOT interfere with Hydro One during utility work. There will be heavy machinery working around high voltage power lines.

Questions or concerns about the utility work can be directed to:

Vibration Monitoring

Please note that NO ROAD CONSTRUCTION will start until the vibration engineer has completed their pre-condition assessment. There will be educational material sent in advance about the pre-condition assessment process, how vibrations will be monitored, the various vibration thresholds, and the claim process for any damages. Residents can expect preliminary information to be sent in the coming weeks.

The Township would like to thank everyone who attended the Public Information Centre to learn more about the Kettleby Road Reconstruction project. Your participation is appreciated and we value your feedback to keep the community engaged throughout the process. See the summary below on the comments/questions/concerns raised at the PIC:

Purpose of this Project

The current (and previous) Road Needs Studies identifies Kettleby Road as having a “Poor” condition rating. Meaning, it currently sits in a state of disrepair that is not favoured by the level of service that should be provided and requires complete reconstruction as soon as possible. Repaving of the existing road is not feasible due to the deteriorated underlying structure and requiring an approach to improve drainage.

Keeping the road in the current condition increases maintenance costs, Township insurance premiums, likelihood of accidents and the risk of drainage impacts can decrease property values.

Tree Trimming & Removals

The current design significantly reduced the amount of trees/shrubs/etc. that need to be trimmed or removed compared to earlier plans. Both Hydro One and the Township have designed the utility and road layouts to save as many existing trees as possible. The only removals are direct conflicts with power lines or proximity to construction works where survival is unlikely. Tree Protection Zones will be placed around nearby trees and the contractor will be required to Hydrovac or airspade when excavating around roots. Where root pruning is required, it will be done under the direction of an ISA Certified Arborist and backfilled as soon as possible.

New Tree Plantings and Restoration Works

The final restoration following construction will include planting of new trees to compensate for the ones being removed. We are currently drafting a Planting Plan to find locations where new trees can be placed. This will be shared with residents when ready. The request for hanging flower baskets will be included in the 2025 beautification program.

Vibration Monitoring

It will be the contractor’s responsibility to retain a vibration engineer when the Township awards the project. Residents can expect educational material and will be able to ask specific questions about the vibration monitoring process. When a vibration expert is brought onboard, one of the first steps will be the Pre-Condition Assessment to document the current state of building foundations. We will provide at least 2 weeks notice to ensure residents can provide access to their homes.

Traffic Calming

A speed assessment will be completed following construction. If warranted, traffic-calming measures will be implemented in the community. These may include: speed humps, bollards, speed cameras, and/or designating the area as a Community Safety Zone.

Curbs

The Township requires barrier-style curbs for all new urbanized road construction. These provide better storm drainage by containing runoff within the roadway. They also serve as a deterrent so vehicles park entirely on the road without encroaching onto the boulevard. The Township will review the engineering and safety aspects of localized rollover curbs.

On-Street Parking

Residents and visitors will still have the option for on-street parking (i.e. at the curb) following construction. Kettleby Road does not have year-round parking restrictions, however is still subject to Township Parking By-law (2005-36) which includes no street parking on any Township road from 2:00 AM – 6:00 AM (Nov 1 to April 15). New or modified parking restrictions will be considered during the traffic calming review.

Signage and Access During Construction

Access to properties will be maintained throughout construction. Other signs and measures include:

• Detour signs on Keele & Jane in both directions that Kettleby Road is under construction
• Contract sign at both ends with contractor/engineer contact info
• Digital message board at both ends to be updated throughout construction with message that Dorio’s is Open
• York Region Police paid duty officers during first few days of construction
• Standard construction signage for traffic control/safety

Communication Plan

Residents can expect to receive a project update at least every 2 weeks or more frequently as major milestones. Updates will be sent using the SpeaKing page distribution list and major milestones will be posted to Township social media channels. Property owners will be contacted individually if there are specific impacts to private property.

Guide Rail at Bridge

While this area is not part of the construction project, the Township will review the guiderail placement and pedestrian safety comments.

Next Steps

• June 21 – Project posted to the Township’s procurement website for contractors to bid
• Ongoing – Design refinements with engineer from PIC resident feedback
• June-July – Hydro One utility work (pole relocations, forestry work, moving lines)
• August – Anticipated start of road construction
