Updates on Construction on Exshaw Creek Flood Protection Project

Update October 16, 2019

A potential safety concern was identified from a steep slope above the east side of the pedestrian bridge and walking path. In order to mitigate the safety concern from rocks falling onto the walking path, a small amount of the berm will be trimmed down at the south end. A few trees will need to be removed near the top of the berm. The goal is to reduce the safety risk while taking a minimalist approach to the berm trimming and tree removal.

The Articulated Concrete Block (ABC) mattresses have been arriving and this part of the project is now moving forward.

The pedestrian bridge is expected to arrive and be installed in late October.

Update October 11, 2019

The new pedestrian bridge is scheduled to arrive and be installed the week of October 21st. This bridge, and connecting gravel pathways on the east and west sides of the creek down to Highway 1A, should provide a nice trail loop for residents of Exshaw. 

The grading elevation of the Lafarge property adjacent to Windridge Road is now mostly complete. 

Other than the ACB (articulated concrete block) mattresses, the project is on schedule and activity is starting to wind down.

Update October 3, 2019

Two of the major components of the project are nearing completion:

1) The debris retention structure, which is located at the far north (upstream) end of the project area, is nearly complete. This structure is designed to stop trees and large boulders from being swept further downstream during a flood. 

2) The concrete abutments for the pedestrian bridge have been constructed. The bridge is scheduled to arrive in late October.

The delivery of some of the ACB (articulated concrete block) concrete mattresses has been delayed by several weeks, due to manufacturing delays. This is the only component of the project that is behind schedule.

A landscaping plan has been completed for the 7.5 meter wide strip of Municipal Reserve that lies between the Lafarge property and the sediment basin (on the east side of the creek). We will be sharing this landscaping plan with the public on Monday, October 7th from 2-6 pm at the MD office. 


Update September 23, 2019

Two major milestones were completed in the last week:

1) The concrete pilings for the debris retention structure were poured.

2) The concrete abutments for the pedestrian bridge were poured.

The delivery of some of the concrete mattresses has been delayed by several weeks. The implication of this delay to the timing of completion of the project is not yet clear.

A landscaping plan has been completed for the 7.5 meter wide strip of Municipal Reserve that lies between the Lafarge property and the sediment basin (on the east side of the creek). We will soon be announcing  a date for a public information event to share the landscaping plan.

Update September 12, 2019

The project continues at its busiest, with several subcontractors on site. We expect another month at this level of construction activity.

Thank you to the residents of Exshaw for their continued co-operation and patience during construction

Update September 4, 2019

Fortis will be moving a couple power poles near the highway 1A bridge next week - watch for construction signs and flag persons.

The material screening is back on schedule and should be completed by mid-September. Thanks to the residents of Windridge Road for your patience as we complete this important task.

Update August 29, 2019

We are approaching the end of month 5 of the Exshaw Creek project. Thanks to the hard work and good management of Devcon (the main contractor) and Golder (the engineer) the project is still on schedule. We anticipate the major components of the project will be completed by the end of October.

The next 6 weeks will be the busiest of the project, with installation of the ACB (articulated concrete block) mats, construction of the pedestrian bridge, moving two Fortis power lines and installation of the debris retention structure. For some project components, work will continue 7 days/week to ensure the project is completed on time.

Update August 23, 2019

Since the Exshaw Creek project started on April 1st, ~470,000 liters of water have been used for purposes of dust mitigation! We would like to thank Devcon for their ongoing diligence to minimize dust from the construction project.

Update August 14, 2019

There are two items that are slightly behind schedule: screening of the native material to produce bedding material, and installation of the ACB (articulated concrete block ) mats. The delays were caused by screener mechanical problems and late arrival of the ACB mats. In order to catch up, the contractor will be working on these two activities 7 days/week for the next 4-6 weeks.

Update August 9, 2019

Construction activity is now ramping up in the area between Highway 1A and the Bow River. As a result, there will be an increase in construction traffic in this area, so please watch for construction vehicles and flaggers. There may be some brief delays.

The area between the bridges has not been fenced off due to Right Of Way limitations, and we ask all residents to please stay out of this area, for obvious safety reasons. 

If you have any questions, concerns or comments please contact Doug Fulford at 403-493-0314.

Update August 1, 2019

The focus of the project is now moving further downstream, to the area south of Highway 1A. As a result, the construction area south of Diamond Drive has now been fenced. The trailhead, sign and garbage bin have been relocated slightly east of the project limits, south of Diamond Drive, so that trail users can still access the Bow River.

The area between the bridges has not been fenced off due to Right Of Way limitations, and we ask all residents to please stay out of this area, for obvious safety reasons.

Major activities in the next month include completion of the gas pipeline move, raising two power lines and installation of concrete blocks downstream of the sediment basin. Placement of rip-rap armouring continues throughout the project area, and excess material continues to be hauled to Lafarge.

If you have any questions, concerns or comments please contact Doug Fulford at 403-493-0314.


Update July 26, 2019

The Exshaw Creek project continues to proceed as scheduled.At this point, the MD would like to take a moment to recognize the following:

Our contractor,Devcon, and project manager, Golder, for keeping the project on track and on budget.

The Government of Canada and Province of Alberta for funding contributions.

Lafarge for the contributions of materials.

In addition, the MD would like to thank the residents of Exshaw for their continued co-operation and patience during construction.

Update July 17, 2019

The project is starting to reach the exciting stage, as it really starts to take shape. The armoured channel, sediment basin and weir, which together provide the majority of the flood protection, are now visible. 

Update July 10, 2019

Nothing new to report. We are approaching the halfway mark and the project is still on schedule.

Update July 3, 2019

The project is now slightly ahead of schedule, since heavy creek flows have been infrequent and short lived. Construction activity is going to increase for the next 3 months, as additional subcontractors arrive to construct the debris retention structure, install Articulated Concrete Block mats, move a gas pipeline, raise a powerline and construct the new pedestrian bridge. Speaking of the pedestrian bridge, a decision has been made to change from a concrete bridge to a steel bridge. Aside from being slightly cheaper, the steel bridge has the advantage of being 0.5 meters wider (2.0 meters v.s 1.5 meters), which means more room for bridge users to pass each other. The steel bridge will look similar to the one across Cougar Creek just upstream of Highway 1. 

With each day, the level of flood protection for Exshaw is increasing. Channel armouring is nearly complete as far downstream as the construction trailer and the large sediment basin is currently being excavated.

If you have any questions, concerns or comments please contact Doug Fulford at 403-493-0314.

Update June 26, 2019

The Exshaw Creek project remains on schedule, however the one task that is falling behind is the screening of material. The screener is the machine that separates the different sizes of material from the native material in the project area. Certain sizes of the screened material are used as a bedding layer between the native ground material and the rip rap. With the screening operation falling behind, there is a risk that the whole project could fall behind and be extended beyond the scheduled completion of late October. In order to stay on schedule, the screener will be running on Sundays, if required, for the next several weeks to enable the contractor to catch up on the supply of bedding material. Having said that, the contractor may be working reduced hours for the coming long weekend.

Happy Canada Day everyone!


Update June 21, 2019

The project continues to proceed on schedule. We have been fortunate that recent rainfalls have helped control the  dust, but last week's rain/snowstorm caused some delays from heavier flows in the creek. With significant rain in the forecast, it is possible that further delays could be experienced in the coming week. Devcon has stopped working on dismantling and armouring  the east bank for the time being to ensure that the hamlet of Exshaw is protected in the event of a heavy rainfall.


Update June 14, 2019

Nothing new to report for week 11. The project is still on schedule.


Update June 7, 2019 

The Exshaw Creek project continues to progress on schedule and on budget. This is already week 10! 

Residents on Windridge Road have raised concerns about dust coming from the construction site.  It is not possible to complete a construction project of this size without creating some dust. Devcon has done a great job of using their water truck to minimize the impact of dust to Exshaw residents.  However, dust will blow during dry windy conditions. We expect dust to become more of a problem in July/August when we enter the dry season. We are exploring additional dust mitigation measures, but it will not be possible to completely eliminate dust blowing from the construction site. 

The water flow in the creek is being diverted to the west side of the creek, so that work can begin on the east bank. The large stockpile of class 3 rip-rap you see is for armouring the east bank of the creek. The east side of the creek bank will be dismantled and rebuilt in 30m sections, to ensure that the hamlet of Exshaw is not left unprotected during the spring run off.


Update May 30, 2019 Exshaw Creek Construction Update

The weather continues to cooperate and good progress is being made. A different material screener was brought on site this week. This screener is intended to be quieter and more durable. Also of note is that the old yellow pedestrian bridge will be moved off site early next week.

Our goal continues to be to complete the project on time, on budget and to provide high quality flood protection for both Lafarge and the residents of Exshaw.

Update- May 24, 2019 Exshaw Creek Construction Update


Construction progress for Exshaw Creek continues to be good and is moving along. The weather has co-operated and the flows in Exshaw Creek continue to be low.

The hauling of riprap started on May 06, 2019. The work has been focused on the placement of Class 4 riprap along the West (Lafarge) Berm. After the west side is complete, the Contractor will remove the riprap from the east side and reconstruct the berm with Class 3 riprap. The re-construction of the east berm will be completed in small stages to minimize the risk to the residences should there be an unexpected sudden flow in Exshaw Creek. The Contractor has the required equipment on site to place riprap on the berm as required to ensure the continued protection of the residences.

Excavation continues for the sediment pond and construction of the east berm. The Contractor has widened and deepened Exshaw Creek from the old (yellow) pedestrian bridge to the Highway 1A bridge to provide the safe passage of water through the construction site. The widening of the creek has limited the extent which the sediment pond can be excavated until the freshet (run-off) has passed.

The excavated material was used to construct the material stockpile along Windridge Road. The screener/sorter started operation on May 13, 2019 in the laydown area across from Windridge Road. This machine is noisy and dusty, and it is estimated to be required to operate until the end of July to produce the required material for the Project. The contractor has extended the berm on the north side as far as possible to minimize the noise to the condominiums. A water truck is on site and continues to spray water within construction site to minimize the dust. The contractor has also watered Windridge road to minimize the dust from the haul trucks. This is the most unpleasant parts of the Exshaw Creek project, and we apologize for the noise and dust. 

Thank you in advance for your understanding. When this project is complete, the residents of Exshaw will be significantly better protected from flooding from Exshaw Creek.

Questions or concerns please contact Doug Fulford, Director of Flood Recovery, at 403-493-0314.


Update- May 16, 2019 Exshaw Creek Construction Update


Construction on Exshaw Creek will cease for the May long weekend. Devcon Inc. will be shutting down this Friday, May 17th at 7:00 p.m. No construction will take place Saturday, Sunday and Monday. Work will commence again at 7:00 a.m ,Tuesday,  May 21. Construction staff will be monitoring the site over the weekend.


Update- April 25, 2019 Exshaw Creek Construction

 

Construction progress for Exshaw Creek has been good and is moving along. In general, work on the creek will initially be focused at the upstream end of Exshaw Creek and continue downstream over the course of the project. 

A material screener/sorter will soon be starting operation in the laydown area across from Windridge Road. This machine is going to be noisy and dusty, and will be operating until at least July. This is likely to be one of the most unpleasant parts of the Exshaw Creek project, and we apologize in advance for the noise and dust. 

**All attempts will be made to minimize dust and to complete this part of the project in the shortest time possible.**

Thank you in advance for your understanding. When this project is complete, the residents of Exshaw will be significantly better protected from flooding from Exshaw Creek.

Questions or concerns please contact Doug Fulford, Director of Flood Recovery, at 403-493-0314.


April 1, 2019

The M.D. of Bighorn is proud to announce that construction of the Exshaw Creek flood protection project will begin the first week of April 2019. This project will provide significant flood protection for the residents of Exshaw.

With the project about to begin, we would like to remind the residents of some important safety and other considerations with respect to the project:

  • The Contractor is Devcon Inc.
  • Construction will be starting on April 01, 2019 and will continue through October 2019.
  • Beginning on April 01, 2019, the west side of Windridge Road will be closed to parking.
  • Construction hours will generally be 7am – 7pm Monday through Saturday. There will occasionally be days when construction activity continues until 10pm.
  • A temporary steel panel fence will be installed to isolate the construction area and will prevent access to the construction area. Only construction personnel with proper personal protective equipment (PPE) which includes steel toed safety boot, high visibility vets, hard hat, safety glasses and hearing protection and a Contractor safety orientation will be allowed onto the work site.
  • The existing Exshaw Creek pedestrian (yellow) bridge will be removed as part of the construction project. The Exshaw School has been notified of the bridge closure. All pedestrians will be required to cross Exshaw Creek using the Hwy 1A bridge. A pre-cast concrete bridge will be constructed to replace the existing pedestrian bridge and is anticipated to be open for use by the Public in late October 2019.
  •  The construction area will be inherently dangerous with large machinery working, and the area should be avoided by the general public.
  • Due to safety concerns at the Lafarge Plant, off road transport vehicles will not be able to access the Lafarge quarry from the construction site. Rip-rap will be transported using highway trucks accessing the construction site from the Lafarge Plant using HYW 1A and the south portion of Windridge Road.
  • The construction project is going to be very noisy:
    • A gravel screening machine will be used to produce materials required for the Project from the excavated creek bed material.
    • Trucks will be hauling rip-rap to the site from the Lafarge Plant. The trucks will be dumping the rip-rap at various locations around the construction site.
    • Heavy equipment will be used for the creek excavation, construction of the berms and placement of the granular material and rip-rap bank armoring.
    • Piling equipment will be used to install the large steel components for a debris trash rack.

Updates of the progress of construction will be posted on the MD’s website and other social media.
