Frequently Asked Questions

General FAQs

Impacts of November 2021 Flood

What immediate emergency response measures were taken during the November 2021 flood?

The city conducted rapid dike inspections, channel dredging, bank armoring, and installed HESCO baskets with the help of the Merritt Fire Department and Canadian Armed Forces.

What resources were available for residents recovering from the November 2021 flood?

The City of Merritt, in collaboration with provincial and federal agencies, provided resources and support for recovery efforts, including financial assistance, reconstruction guidelines, and mental health services.

Flood Mitigation Plan

What is the Flood Mitigation Plan?

In January 2022, the creation of a Flood Mitigation Plan was awarded to engineering firm Associate Engineering.  The Province of BC awarded Merritt a total of $329,000 to prepare this plan.

This workplan involved the following 5 phases:

  1. Hydrotechnical Analysis
    • Building a model of the total water flows of both the Nicola and Coldwater watersheds during multiple return periods
    • Incorporating potential climate change effects on future flood events
    • Modelling the effect of these water flows on inundation expectations in the City of Merritt using a HEC-RAS 2D model and a Digital Elevation Model.
    • Generating potential flood mapping of various areas
  2. Flood Impacts and Economic Assessment
    • Using the 2021 Merritt event, the 2018 Grand Forks event, and other flood events to predict potential impacts of future flooding in Merritt using depth-damage analysis
    • Evaluating infrastructure, property, and socio-economic impacts
  3. Environmental and Cultural Assessments
    • Performing a corridor-wide Environmental Overview Assessment (EOA)
    • Performing a corridor-wide Archaseological Overview Assessment (AOA)
    • Phase 1 Environmental Contamination Assessment
  4. Flood Mitigation Options Assessment
    • Using the modelling generated, develop a range of options for flood mitigation infrastructure
    • Options examined were wide, from “what happens if nothing is done”, rebuilding existing dikes, building new setback dikes, river channel dredging, and managed retreat scenarios
    • During the process, multiple open houses were held, Indigenous Engagement sessions, community input opportunities, and extensive consultations with elected Council on an area-by-area basis.
  5. FMP Finalization
    • Based on the work done, a conceptual plan for each at-risk area was created and the final plan used a range of options rather than relying on a single strategy
    • The final Flood Mitigation Plan is intended to be built and operated as a cohesive system

In November 2022, this final Flood Mitigation Plan was adopted by City Council.  This finalized document was given to the Merritt Flood Mitigation Team as a guiding and enabling document.

How is the infrastructure in the plan funded?

No single source is able to fund the $130-$160 million required for the complete build-out of the Flood Mitigation Plan.  Additionally, the expense of this program would not be feasibly supported by the tax base within the City of Merritt.

However, a future flood event similar to the November 2021 event would be expected to incur well over $200 million in disaster response and recovery costs to multiple levels of government, so Merritt elected officials have been strongly messaging senior government that it is wiser to pay to protect rather than recover.

One of the initial and primary tasks assigned to the Flood Mitigation Team is breaking the overall Flood Mitigation Plan into separate discrete projects that will qualify for the limited and competitive funding that is currently available from senior government.

To date, multiple projects have been funded through the Province of BC’s Disaster Risk Reduction grant stream, Provincial Disaster Financial Assistance, Federal Investing in Canada Infrastructure funds, and several off-program funding sources.

One of the large grant programs identified was the federal Disaster Mitigation and Adaptation Fund.  In 2024, under advisement from the Federal and Provincial governments, the City spent significant amounts of time and funds to apply for this program.  Unfortunately, the City was denied access to funds under this program.

During the November 2021, Minister Bill Blair visited Merritt and promised that the federal government would help Merritt build protections against future funds.  Merritt staff and elected officials continue to advocate to the federal government for reconsideration under the DMAF program, or direction for another funding source to make good on this promise.

Indigenous Engagement Plan

Why do we have an Indigenous Engagement Plan?

Indigenous engagement is crucial in British Columbia, especially given the province’s unique history, geography, and legal landscape. BC is home to a diverse range of Indigenous Nations with deeply rooted connections to their lands, cultures, and communities. Many of the lands where construction projects take place are unceded, meaning Indigenous rights to these lands were never formally surrendered or extinguished through treaties. This adds an additional layer of responsibility for municipalities and other project leaders to engage with Indigenous communities.

Indigenous peoples have inherent rights, including the right to self-determination, control over their lands, and protection of their cultural practices. Engaging Indigenous communities helps ensure these rights are respected and upheld, in alignment with national and international standards like the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP), which BC has committed to implementing.

Engaging early and meaningfully with Indigenous communities helps foster strong relationships based on trust and respect. This can help avoid conflicts, delays, or misunderstandings during the project and create long-term partnerships that benefit both parties.

Indigenous communities offer valuable insights into local ecosystems, cultural practices, and sustainable resource management. Their input can help improve the social, environmental, and economic outcomes of construction projects, leading to more responsible and well-rounded developments.

By integrating Indigenous perspectives, respecting their rights, and ensuring that their voices are heard throughout the process, municipal construction projects in BC can move forward in a way that is legally compliant, ethically responsible, and more likely to succeed.

What is the Flood Mitigation Indigenous Engagement Plan (IEP)?

The IEP was built together with the 6 Nicola Valley Indigenous bands, and started with a single question.  “How can we work together to build better communication and relationships?”

The Indigenous Engagement Plan answers this question through several information sharing commitments, based on what we heard from our surrounding partner communities and land rights-holders.  These commitments reflect our desire to engage early and often, provide predictable two-way communication, and ensure honest and transparent efforts are made to receive and integrate input into projects during the planning stage.

This IEP applies to all projects undertaken by the Merritt Flood Mitigation Team, while also building pathways and relationships with City of Merritt staff and elected officials and all Nicola Valley bands.

What Indigenous Communities are included with the IEP?

  • Coldwater Indian Band
  • Cook’s Ferry Indian Band
  • Lower Nicola Indian Band
  • Nooaitch (Noo-eye-ch) Indian Band
  • Shacken Indian Band
  • Upper Nicola Band

How are projects communicated with the Bands?

The Indigenous Engagement Plan outlines specific and repeatable engagement opportunities for each individual project.  While additional engagement opportunities may be added on certain projects, these specified engagement points were identified after significant discussion with Nicola Valley bands.

Flood Risk and Prevention

Where can I find information about potential flood inundation zones within the City of Merritt?

The City of Merritt has a currently-underway project to provide risk-based mapping to residents.  This project is outside the scope and authority of the Flood Mitigation Team, and is being undertaken as a joint project between the Emergency Program Coordinator and the Department of Public Works.  Expect additional information on this initiative from the City of Merritt in 2025. 

What steps is Merritt taking to prevent future flooding?

The comprehensive Flood Mitigation Plan adopted by council in 2022, once fully built out, is expected to protect City residents and infrastructure from a future 1-in-200 year flood.

The City of Merritt has received Provincial funds to establish a temporary Flood Mitigation Team, with the responsibility to find funding and execute this plan.

You can view the Flood Mitigation Plan online here.

What are the key components of the Flood Mitigation Plan for Merritt?

The Flood Mitigation Plan identified 7 different strategic areas where flood mitigation infrastructure is required.  After community and indigenous consultation, specific protection measures were evaluated on a multi-criteria analysis using 5 specific areas.

FMP key components

The ending plan consisted of a variety of flood mitigation methods, including: dike rebuilding, new dike building, pump stations, river dredging, moving infrastructure, and managed retreat. 

 

What long-term changes are expected in Merritt's hydrologic regime due to climate change?

Updated maximum river levels are due to two different factors:

  1. An increased understanding of the Coldwater River watershed.
    • Additional hydrological engineering has increased our understanding of potential flow rates in the Coldwater River.
    • Infrastructure was initially build to withstand a 1-in-200 year flood of approximately 130 cubic meters per second of flow.  Updating understanding has increased this 1-in-200 year event to 376 cubic meters per second.
  1. Updated climate change predictions to comply with Government of BC regulations.
    • All new engineering of flow rates on rivers in BC needs to contain an adjustment for climate change.  While this is not an exact science, several engineering firms have produced reports indicating a range of potential increases in flow rate.  This has resulted in an additional 29% being added to the potential 1 in 200 year flow rate.

These two factors combined have seen the need to increase our infrastructure to accommodate a flow rate of 490cms. 

This large variance from the pre-2021 value of 130cms means that any dikes that would be permitted by the province would need to be substantially higher and wider, or alternatively they would be set back further from the river, allowing more space for flooding.

Property and Insurance

How will the Flood Mitigation Plan affect property values and insurance in Merritt?

While the plan aims to reduce flood risk and enhance safety, property values and insurance rates may be influenced by new floodplain designations and the implementation of mitigation measures.

Does the City of Merritt have any plans to buy properties in the potential inundation zone of the Coldwater River?

This diking system will be built as a setback dike, which will require additional land along the Coldwater River.  Part of the funding for the project includes full and partial acquisitions for certain properties along the river.

These property acquisitions have been costed and planned by a third party, and all discussions and purchases will be conducted by a third party, not directly by City of Merritt staff.

If you have any questions regarding how your property may be directly affected, please email floodmitigation@merritt.ca, include your name, address and questions.

potential inundation zone of the Coldwater River

Technical Information

Did Merritt have any flood mitigation infrastructure prior to the November 2021 flood?

On the Coldwater River, the City of Merritt is the owner of 2 provincially regulated dikes, with Dike 129 on the West side of the river, and Dike 130 on the East side of the river.

Unfortunately, during the 2021 flood event, the majority of this infrastructure was washed away. The Province of BC has not allowed the rebuilding of this infrastructure on the current alignment, so an alternative alignment will need to be used for much of this diking in the future.

Answers to Frequently Asked Questions Merritt Flood

What peak flow rate was previous infrastructure designed for?

When constructing registered dikes, the Province of BC Diking Authority requires structures to be built to withstand a 1-in-200 year flood. Modern convention has required the Engineer of Record to add an extra amount to account for future climate change to this total. This modelling indicates a total water flow expected in a flood period, expressed as a number of Cubic Meters per Second (CMS).

The most recent analysis was done by BGC Engineering, and a draft copy was made available in 2021, shortly before the flood. This report indicated a 1-in-200 year standard of 154 CMS, and a 1-in-500-year expectation of 163 CMS.

This compares closely to previous studies done. The Province of BC had previously estimated a 1-in-200-year level of 138 CMS, and a 1-in-500-year level of 148 CMS. Even further back, the Nicola River Floodplain Mapping project in 1988 indicated a 1-in-200 year flow of 148 CMS.

Infrastructure existing along the Coldwater was built to the existing standards and engineering knowledge at the time. For example, the Middlesboro Bridge was built in 1974 and built to a standard of under 150 CMS.

Dike 129 and 130 were initially constructed as temporary flood protections after an ice jam flood in the early 1970’s. Subsequent ice jam and other flooding events occurred on the Coldwater River, and these dikes were rebuilt and realigned multiple times over the intervening decades.

The flow levels these structures were designed for varies based on the construction, but generally they were designed for extreme flow rates between 120 CMS and 150 CMS.

What peak flow rate occurred during the November 2021 flood?

The short answer is that we don’t know for sure as the flood event broke all the gauges, but the best guess is 320-400 CMS.

Significant research was done by multiple agencies after the flood event, using a variety of engineering techniques from rainfall analysis, volumetric studies, and even video water-speed analysis.  Coldwater River flow estimates from the BC River Forecast Center, Canadian Hydrographic Service, multiple engineering firms, and even an academic paper initially indicated flows from 180 CMS to 450 CMS, which was later refined to 320-400 CMS.

Additional Questions

We have learned that Merritt has had past floods in the eighties and nineties and now the recent one: why haven't the dikes been brought up to standard, and when can we expect them to be done?

The Flood Mitigation Team is worked closely with engineers and other professionals to investigate the most effective way to rebuild important infrastructure and created the Flood Mitigation Plan. In the meantime, the dikes are expected to be able to manage the anticipated spring run-off.

Is the City of Merritt considering dredging the Coldwater or Nicola Rivers?

Rivers fall under provincial jurisdiction and we understand that the province is considering this option and is in the process of balancing various considerations.

Will the City be purchasing homes for those who do not want to rebuild?

There is no identified funding for such purchases. The City of Merritt encourages homeowners not to delay rebuilding and repairing their homes.

We're eager to move forward with rebuilding our basement, fence, or replace our doors, but we're hoping to get clarity from the city first.

Weather

Is the City still monitoring the weather?

Yes, the weather and river flow forecasts continue to be monitored by the City and Province

What role does climate change play in the November 2021 flood, and how is it being addressed in future planning?

Climate change has been identified as a significant factor, contributing to more extreme weather events. The Flood Mitigation Plan incorporates climate change projections to ensure resilience against future conditions.

What is the difference between flood watch and flood warning?

Warning: river levels have exceeded bank-full or will exceed bank-full imminently, and flooding of areas adjacent to the rivers affected will result.

Watch: river levels are rising and will approach or may exceed bank-full. Flooding of areas adjacent to affected rivers may occur.

Dike FAQs

Ownership and Inspection

Are dike condition inspections happening, and why are they important?

The DMA requires dike inspections to occur on a yearly basis.

In addition to being a legal requirement, these dike inspections are critical to inform preventative maintenance and potential issues with dike construction.

Design and Construction

Will the dikes change?

The Flood Mitigation Plan does indicate significantly different structures and locations required to provide protection of residents and critical infrastructure.  This is due to substantially increased expected flow rates, and significantly different minimum requirements for dike construction. 

For example, the previous dikes were constuctred decades ago, but new dikes are required to have a 4 meter wide access way to the entire dike structure, which substantially increases the footprint required.

What are the lengths of each dike in the Coldwater River?

Funded Diking Sections
C-EPA N Dike 407 = 270m
C-EPA Claybanks = 190m

Unfunded Diking Sections
C-EDR Dike 129 = 1.56km
C-EDR Dike 130 = 1.34km
C-EPA Middlesboro P1 = 90m
C-EPA Middlesboro P2 = 135m
C-EPA Middlesboro P3 = 550m
C-EPA Godey = 740m

Previously Funded Bank Stabilization
Fir Ave Bank = 120m

Why do we need to cut down the trees to build a dike? Don’t the trees help to contain the river?

Natural shorelines, formed by the river itself, rely heavily on vegetation to stabilize the banks. This method works only in areas where the river has much room to meander side to side. This decreased shoreline stress would allow vegetation to quickly regrow and reinforce any sections that might erode when a tree falls, keeping the area stable even during high water levels.

In contrast, man-made dikes function differently. In Merritt, with narrow river corridors running through town due to often unchecked shoreline development over the expansion of the City since its inception, there simply isn’t enough space to support a natural river flow in all areas.

This is why our diking system is necessary.

Unfortunately, if there were tree’s rooted in or near the rock structure of these dikes, it would pose a significant risk. When a tree falls, it will pull part of the dike structure with it. With the confined spaces and the new reality of high water flows, this can and will lead to a breach, resulting in flooding and damage to the community once again.

It’s difficult for our team each time a tree is removed. The Flood Mitigation, Design, Environmental and Engineering teams look at all the options for each section to minimize environmental impact both in the water and on the shoreline with all of our projects.

What is the Procurement Process for Projects?

The City will generally conduct a quote or competition process for procurements, in accordance with its purchasing policy, to ensure that the City achieves best overall value. Most procurements for this project are anticipated to exceed the thresholds* of the New West Partnership Trade Agreement (NWPTA); which is a trade agreement between the Provinces of British Columbia, Alberta, Saskatchewan and Manitoba; and are therefore required to be conducted through open public competition (e.g. a publicly-advertised Request for Proposals or Invitation to Tender process).

One objective of the NWPTA is to promote open and free trade among Canada’s Western Provinces, meaning that the City must provide equal treatment to all companies that bid such public competitions, regardless of whether such companies are considered local or not.

That said, companies that are based locally will often have an inherent advantage of lower costs to reach the site, and the City actively encourages local companies to engage with procurements issued by the City.

Local companies may contact the Flood Mitigation Team to gain updates on potential procurement windows for the project and are advised to register on BC Bid (https://www.bcbid.gov.bc.ca) where companies can receive certain notifications. When the City issues a public competition which exceeds the NWPTA thresholds*, it will be advertised on BC Bid and the competition details will include full instructions on how a company can register and participate in the competition. A contact person is also provided for each competition in case a potential bidder has questions on how to submit a proposal.

*Note: Under NWPTA, public competition is required >$75k for goods/services, >$200k for construction.

I want to get a job on one of the projects, how would I do that?

In accordance with the City’s Purchasing Policy and requirements of the New West Partnership Trade Agreement (NWPTA); most contractors that work on the project will be selected through open public competition, to ensure that the City achieves best overall value. 

The City will often recruit a ‘general contractor’ for construction, that will in-turn likely contract with ‘subcontractors’ and suppliers.  Individuals that are interested in working on the project may wish to seek out firms that are likely interested in participating in the project either as a general contractor or subcontractor/supplier. 

Due to requirements for open public competition under NWPTA, and under a typical City agreement with contractors; the City cannot influence contractor hiring and recruitment decisions, however the City will be able to provide a list of companies that register for most competitions and local individuals may contact these regarding job opportunities.

Pathways and Flood Risk

Will there be new pathways constructed on the dikes?

The tops of the dikes will be incorporated wherever possible in a Active Transportation Plan for the city of Merritt. More information can be found on the City of Merritt website here.

Additional Information on the City of Merritt’s Official Community Plan (OCP) is available here: https://www.merritt.ca/ocp/

Project FAQs

Dike 129/130 Program

What is the Dike 129 / 130 Program?

The Dike 129 / 130 Program is a key component in Merritt’s comprehensive Flood Mitigation Plan, which identifies multiple dike projects aimed at reducing flood risk throughout the community.

Specifically, the Dike 129 / 130 Program focuses on constructing and upgrading dikes along critical sections of the Coldwater River to enhance flood protection and improve the overall resilience and safety of Merritt.

Voght Wells and Dike Breach

Why is this program necessary?

The City of Merritt had protective diking structures prior to the 2021 Atmospheric River Event (ARE) but they were destroyed during the event. These structures were built to withstand up to 130 cubic meters per second of water.

The 2021 ARE saw volumes between 320 and 400 cubic meters per second. Current engineering predicts a new 1-in-200-year flood of 490 cubic meters per second, which puts 1,144 additional houses in the updated flood zone.

New construction must be certified to a 1-in-200-year standard, so Merritt was not able to build back the pre-existing dike and would need to build new structures to accommodate 280% more water. Engineering this sort of upgrade and finding land to put the new diking on is a significant and unique challenge, and Merritt has been working closely with the Province of BC since the 2021 ARE to solve this challenge.

This project will dramatically lower the risk of future flooding in Merritt, allow protection of homes and critical infrastructure, provide resident financial and personal security, and allow Merritt to truly move on from the devastating 2021 flood.

Where will the new dikes be located?

The structures funded under this announcement run from the newly constructed Middlesboro Bridge down to the confluence of the Nicola and Coldwater Rivers.

These structures will be significantly more resilient than the prior diking and will also be constructed in a more ecologically sensitive manner. Priority has been given to building setback dikes, which is possible in approximately 70% of the 2.9km of diking. Therefore, the river will only touch the diking structures during periods of high water.

During much of the year, this project will provide ‘room for the river’. This project will also increase riverside habitat, public recreation space, and decrease maintenance costs compared to a typical waterside dike.

Specific diking footprints will be updated as the project progresses into detailed engineering, and flood.merritt.ca will always have the most up-to-date information on this project.

Dike 129/130 Project

Does this solve all of Merritt’s diking needs?

This announcement covers a large portion of the diking system, but not all of it. The council-adopted 2022 Flood Mitigation Plan contains 4.9km of diking and 390 meters of bank stabilization on the Coldwater River.

This announcement allows the building of 2.9km (60%) of the system. Importantly, this section of diking is anticipated to be the most complex to build and provides significant city protection from future Coldwater River flooding.

An additional 0.46km (10%) of the diking has already been funded by other Provincial funding sources.

This leaves a further 1.5km (30%) of diking along the Coldwater that is not yet funded. The City will continue to work with Provincial sources but will especially be looking towards the Federal Government for assistance on the remaining components of the diking system.

What is the cost of this program and what does it include?

The $60 million announcement includes the costs of detailed engineering, land acquisition, environmental and archeological studies, dike construction, and environmental offsetting costs.

Who is funding this program? Is this Provincial funding or Federal funding?

This funding is provided by the Government of British Columbia, through the Ministry of Emergency Management and Climate Readiness. Please refer to the associated Press Release located here.

This $60 million is being provided by the Province of BC to Merritt. While the federal government promised aid in rebuilding and mitigation during the 2021 event, federal funding has been absent since that time.

Direct federal contribution has been limited to $2.3 million for the STUWI(x) project. The City of Merritt applied for the federal Disaster Mitigation and Adaptation Fund, but was rejected from this program, and no other direct federal funds have been received.

How long will this program take?

The City of Merritt is thankful to have completed the vital Public Works diking project in fall 2024 and is using the information gathered from that project to inform the larger Dike 129 and Dike 130 Program.

Based on this experience the initial estimated timeline for completion is 4 to 6 years, but this may change as design and construction planning progress. While still in early stages, the project has completed key studies, including conceptual work, costing, and environmental assessments. It now moves into the construction planning phase, with timelines to be released as work advances.

One key challenge is the short allowable work window on the Coldwater River, which is limited to just 11 days per year. Progression and completion of this project will depend on permitting authorities granting permission to work outside this window. Additionally, very few diking projects have been completed in BC over the past five years, creating uncertainty in planning timelines.

For updates, follow along on our Social Media Presence on LinkedIn, Facebook and on our website: flood.merritt.ca

When will construction begin?

The Flood Mitigation Team is responsible for moving the conceptual plan into a construction plan, and then constructing the diking funded in this announcement. This requires detailed engineering and permitting from multiple government bodies that takes from 4-8 months to approve. In addition, the allowable work window on the Coldwater is only 11 days during the summer unless the regulators choose to extend this window.

Construction start and timeline will mostly depend on what is permissible by the regulatory bodies.

As the detailed construction planning and engineering progresses, more timeline details will be made available. For updates, follow along on our Social Media Presence on LinkedIn, Facebook and on our website: flood.merritt.ca

How will Indigenous communities be involved?

The City of Merritt Flood Mitigation Team, together with our surrounding Indigenous partners, have developed a BC-leading Indigenous Engagement Plan (IEP), with a full time Indigenous Engagement Manager who is responsible for implementing this plan.

This IEP is available in its entirety at flood.merritt.ca

Indigenous Engagement Plan (IEP)

Will property owners be affected?

This diking system will be built as a setback dike, which will require additional land along the Coldwater River.  Part of the funding for the project includes full and partial acquisitions for certain properties along the river.

These property acquisitions have been costed and planned by a third party, and all discussions and purchases will be conducted by a third party, not directly by City of Merritt staff.

Contact with potentially affected landowners will occur in 2 stages.

  • Spring 2025 - A letter will be sent out to all potentially affected landowners advising of the potential impacts. Engineering and acquisition staff may be available at this point, but as the final footprint is not set, financial compensation information will not be provided.
  • Fall 2025 – The third-party property acquisition team will contact the landowner to discuss details of the acquisition as the final footprint becomes clearer. All inquiries and discussions will be held at arms-length from the City.  This third-party team will ensure compensation occurs in a fair and timely manner and is in accordance with all applicable laws and standards.

Additionally, as this is a large construction project, many properties and streets will experience temporary construction disruption.  This is anticipated to be the largest project in the history of Merritt, so some patience with construction crews and noise will be needed by us all.

If you have any questions regarding how your property may be directly affected by the Dike 129/130 Project, please email floodmitigation@merritt.ca, include your name, address and questions.

If my property is part of the acquisition, how much will I get?

The final dike footprint will need to be confirmed through a multi-month engineering process, and only after this point will the land acquisition footprint be finalized.  Until that time, compensation offers will not be available.

As per the previous question, potentially affected landowners will be notified shortly, and will be advised of next steps and timelines for valuation and offers on properties.

How can residents support the program?

Residents can support by:

  • Attending public engagement sessions
  • Staying informed and sharing project updates

Is this increased work going to make housing even more challenging in Merritt?

This project is anticipated to significantly alleviate housing challenges within the City of Merritt. Prior to the 2021 event, there were 130 houses in the anticipated floodplain.  Revised engineering after the event indicated 1,274 were in the new floodplain, meaning densifying, building, permitting, and all housing activities are extremely difficult in that area. 

While the ideal plan would be to re-locate all these houses, this is over 35% of the housing stock in Merritt and in addition to the billions of dollars in cost, Merritt does not have developable land to move people to.

Having no flood protections in that area at all meant stagnating neighborhoods and a lack of housing investment.  This protective diking will give homeowners the security and confidence to rebuild homes and will help preserve the very limited building area available for Merritt housing.

Who will own and maintain these new dikes?

The City of Merritt is a registered diking authority, and under Provincial law the city must take ownership of these dikes and maintain them to standards specified in the Dike Management Act.

Reducing maintenance costs was one of the key considerations in the 2022 Flood Mitigation Plan, and the specific dike design has been done to ensure maintenance requirements are lower than traditional diking.

What will be the elevation of these new dikes?

The new diking elevation will vary depending on the location due to the slope of the river and the amount of setback but will be between 0.3m and 1.8m meters higher than the previous diking.

How will rainwater and snowmelt get into the river if there are dikes in the way?

The 2022 Flood Mitigation Plan specifies 2 pump stations to ensure stormwater is conveyed appropriately. 

The first and largest of these is located near the Middlesborough Bridge and is already funded by the Government of BC. 

The second pump station is located near the end of Canford Avenue, and City staff continue to look for funding for this station.

Will the dikes increase risks to downstream property owners?

Eliminating downstream risk transference was a key consideration in the conceptual plan.  The City of Merritt has worked extremely hard to make a flow velocity reduction area before water leaves the City. 

This is the STUWI(x) project, which is funded and underway. 

The STUWI(x) project involves naturalizing 5 hectares of land at the confluence of the Nicola and Coldwater Rivers, ensuring that Merritt diking will not cause increased velocity and flood risk downstream.

What’s happening with Princeton, are they getting support?

The City of Merritt recognizes that each community's flood recovery journey is unique.

While we are committed to supporting regional recovery efforts, we are not able to speak to the specific progress or circumstances of other communities.

I understand you are on top of getting funding for this section of dike, and it is likely to be funded soon. But, is there any specific engineering reason for funding and constructing sections 129 and 130 before the Middlesboro section?

No specific engineering reason.

The path to funding the Dike 129/130 project is different than the C-EPA Middlesboro Phase 1.

Dike 129/130 were existing dikes prior to the flood, and this is actually a ‘rebuilding’ project, although the need to build higher and wider means they will look much different.

The C-EPA Middlesboro P1 section is a brand new dike, and senior government funding opportunities for projects like this are extremely competitive and far more difficult to find and successfully win.

Was it more of a priority to get funding for dikes 129 and 130 over the Middlesboro and Houston sections? If so, what was the reason for that?

The 2022 Flood Mitigation Plan calls for approximately 5km’s of diking work, and several hundred meters of bank protection.

This plan is intended to work as a system, and will only provide full protection when it is 100% complete.

The City of Merritt applied for federal and provincial funding sources for the entire project, but no senior government supported and funded the entire system at once. Additionally, the City of Merritt is not in a financial position to execute this plan alone. Therefore, the Flood Mitigation Team has been working to execute the entire plan in smaller sections, based on current grants and funding sources.

So the priority at this point has been based on whether the project could be funded by senior government.

If another rare flood event were to happen, would the areas neighboured by the unbuilt Middlesboro dike be subject to flooding, or would dikes 129 and 130 protect the entire river in some way?

The protection from Dike 129 & 130 will only serve as protection in that area of the City.

Dike 129 & 130 are part of the 2022 FMP operates as a system, and the Team is working hard to find funding to achieve 100% protection.

Until full completion of the FMP, all other exposed areas would have to be protected by the emergency response capabilities of the City and EMCR. This would include emergency flood protection measures like sandbagging, gabion baskets, and other temporary emergency flood protection methods.

There's a sharp bend at one point in the Middlesboro section of dike on the river. Does that present increased danger of flooding?

The shape of the 5km of overall diking was designed by hydrological engineers and approved by council in the 2022 Flood Mitigation Plan.

As individual sections of dike are funded and built, the hydrological modelling is updated and more detailed engineering is completed.

This may result in changes to the final design of the dike compared to the initial conceptual model, if they are recommended and endorsed by the Engineer-of-Record for the project.

It’s important to note that bends and structure in the river serve to decrease the velocity of the river, lessening the destructive power downstream.

This trade-off between deceleration and efficiently moving water through is modelled and signed off by the Engineer of Record for the diking system.

C-EPA Claybanks Dike Project

When is the anticipated starting date of the dike project? How long is the construction period expected to last, and how will that affect seasonal visitors?

The dike construction is anticipated to begin in June of 2025.

The construction period is expected to last approximately 6-7 month, depending on weather and site conditions.

Seasonal visitors will experience disruptions due to construction activity during peak travel months, but efforts will be made to minimize impacts.

When is the RV Park opening for the 2025 Season?

Early May; watch the Claybanks RV website for their reservation portal to open.

Will the RV Park be open during Dike construction?

Yes, 22 fully serviced public reservable sites will be available, with a limited portion of the RV Park remaining open during construction.

Access will be maintained throughout, and any changes or detours will be clearly communicated in advance to ensure a smooth experience for visitors.

Will the construction reduce RV park occupancy or deter tourists? Will there be any temporary physical barriers or changes to the RV park layout?

Some guests may choose alternate accommodations due to on-site dike construction, which could temporarily affect occupancy.

Temporary fencing and signage will separate construction areas from the RV park, but the park layout will still obtain a perimeter road to ensure vehicles and trailers can safely navigate to their reserved spots.

Will any amenities or recreational access in or around the RV park be restricted during construction?

Identified green spaces adjacent to the construction zone may be temporarily inaccessible for safety reasons.

All other core amenities within the park will remain operational.

What is the current condition of the park?

Please refer to the photos on the Claybanks website  for an update on the park’s current recovery progress.

While key infrastructure has been restored and is fully operational, the natural regrowth of trees and grass is still in its early stages.

With ongoing dike construction nearby, we anticipate it may take 2–3 years for the Claybanks RV Park to return to its pre-flood condition.

Will construction activities increase dust, noise, or air pollution in the RV park?

Yes, there will unfortunately be an increase in dust and noise levels during active construction hours.

Dust control measures (e.g., water spraying, erosion control) and noise mitigation practices will be in place to limit the impact on nearby areas.

Will RV park guests experience disruptions due to noise, vibration, or construction traffic?

Yes, significant disruption is expected.

Construction vehicles and equipment will generate daytime noise and vibrations. Traffic patterns near the park entrance will also be affected during specific phases of the work.

Will construction affect utilities such as water, power, or sewage systems connected to the RV park?

No significant disruptions to utilities are anticipated.

Any planned interruptions will be communicated in advance and scheduled during off-peak hours wherever possible.

Are there risks of construction debris, heavy machinery, or restricted access creating hazards for RV park residents?

Safety is a top priority.

Barriers, fencing, and clear signage will be used to prevent access to hazardous areas.

Construction zones will be physically separated from public access routes.

What safety measures will be in place to separate construction areas from the RV park?

The site will use fencing and posted signage to delineate work areas.

Construction crews will adhere to strict safety protocols, and site supervisors will be on hand to monitor boundaries and public safety.

What are the hours of the dike construction operations?

Typical construction hours will be from 7:00 AM to 7 PM, Monday through Saturday.

No work is expected on Sundays or statutory holidays unless otherwise required.

Will the RV Site pricing be reflective of work happening next door?

Unless advertised on the Online booking system, regular pricing will remain in effect.

Are there refunds available if the work is too loud and dusty?

We understand that the dike construction will be disruptive; however, refunds will not be available due to the high demand, and the clear communication of the RV Parks current recovery state.

We appreciate your patience as this work is essential to safeguarding our community from future flooding.

How do I book online?

Reservation Links will be here: https://www.claybanksrv.ca/

Will there be park attendants onsite?

Where is the Sani-dump?

The Municipal Sani dump is located across the road from the Claybanks RV park.

Note: Each one of our available sites is a fully serviced site.

What hours are bathrooms/showers available?

8am-10pm, Bathrooms and showers will be cleaned mid day.

C-EPA Middlesboro Phase 1

What is the C-EPA Middlesboro Phase 1 Project?

All projects marked as “C-EPA” are in the “Coldwater – Expanded Protection Area”.

This is brand-new infrastructure that didn’t exist before the 2021 flood, rather than the projects related to rebuilding the pre-existing infrastructure.

C-EPA Middlesboro Phase 1, marked in red on the below map, continues the upgraded diking upstream past the in-progress C-EPA Claybanks Project. These two projects will tie in together and provide integrated and systematic flood protection in a flood-vulnerable area of the City of Merritt.

C-EPA Middlesboro Phase 1 Project

 

Why is this project necessary?

Prior to the 2021 Atmospheric River Event (ARE), all flood modelling and protections on the Coldwater River were done with a water flow level of 130 cubic meters per second.  The Nov 2021 ARE saw 320-400 cubic meters per second, and the new flood modelling and protection standard is 490 cubic meters per second.

This means that areas of the City that were not previously in the flood inundation zone, are now at risk and the pre-existing flood protections need to be built to accommodate more flow.

The North bank of the Coldwater River upstream of the Middlesboro bridge is one of these newly at-risk areas and requires new flood infrastructure to protect the residents in this area. 

The City of Merritt has very limited tax dollars available for these large and complex projects, so the project is being built in a phased approach as senior government funding is available.

On February 3rd 2023 the Government of BC awarded Merritt a $2 million grant to build the C-EPA Claybanks Dike.  This new C-EPA Middlesboro Phase 1 project, will continue this diking and get the City of Merritt closer to the completion of the 2022 Flood Mitigation Plan.

Where will the new dike be located?

In the below image, the new diking will be located in the red shaded area.

This is on the North bank of the Coldwater River, upstream of the Claybanks RV Park, between Garcia St and McMillan St.

C-EPA Middlesboro Phase 1 Project

Who is funding this project?

This project is fully funded by the Province of BC, through Emergency Management and Climate Readiness BC.

Modern dikes are large and complex projects, requiring significant engineering, permitting, and earthmoving.

The City of Merritt does not have the municipal tax base to support these critical safety projects, so the Government of BC has stepped in to provide assistance.

Is there any federal funding of this project?

This project is 100% funded by the Province of BC. No federal funding has been provided to the City of Merritt for this project.

How long will this project take?

This project will begin engineering and final design immediately.  One key challenge is the short allowable work window on the Coldwater River, which is limited to just 11 days per year. Progression and completion of this project will depend on permitting authorities granting permission to work outside this window. Additionally, very few diking projects have been completed in BC over the past five years, creating uncertainty in planning timelines. 

This project is currently slated for the summer 2026 construction season, but as noted above, many complexities are required to be solved before then.  Therefore, an alternative construction schedule is being prepared with the earthworks being done in the summer 2027 season.

How will Indigenous communities be involved?

The City of Merritt Flood Mitigation Team, together with our surrounding Indigenous partners, have developed a BC-leading Indigenous Engagement Plan (IEP), with a full time Indigenous Engagement Manager who is responsible for implementing this plan.

This IEP is available in its entirety at flood.merritt.ca

Indigenous Engagement IEP

Will property owners be affected?

Property owners that may be potentially affected will be contacted directly to discuss next steps.

Contact with potentially affected landowners will occur in 2 stages.

  • Spring 2025 - A letter will be sent out to all potentially affected landowners advising of the potential impacts. Engineering and acquisition staff may be available at this point, but as the final footprint is not set, financial compensation information will not be able to be provided.
  • Fall 2025 – The third-party property acquisition team will contact the landowner to discuss details of the acquisition as the final footprint becomes clearer. All inquiries and discussions will be held at arms-length from the City.  This third-party team will ensure compensation occurs in a fair and timely manner and is in accordance with all applicable laws and standards.

Additionally, as this is a part of the overall Flood Mitigation Plan (FMP) project, many properties and streets will experience temporary construction disruption as construction unfolds.

If you have any questions regarding how your property may be directly affected by the Project, please email floodmitigation@merritt.ca, include your name, address and questions.

How can residents give feedback on this project?

The Merritt Flood Mitigation Team can be reached at floodmitigation@merritt.ca, or at flood.merritt.ca/contact-us

Fir Ave Bank Stabilization and Coldwater Projects

What are the Fir Ave Bank Stabilization and Coldwater Projects?

The Fir Ave Bank Stabilization and Coldwater Project in Merritt is a flood mitigation initiative aimed at reducing flood risks and restoring natural river function along the Coldwater River to ensure healthy river diversity and fish habitat.

The scope of the project:

  1. Fir Avenue: This area experienced bank erosion during the severe flooding in 2021, leading to accelerated property erosion. The project involves riverbank stabilization to create a flood-resilient corridor while allowing the river more natural space to flow.

Overall, the project aligns with Merritt’s broader Flood Mitigation Plan, integrating community safety, environmental restoration, and long-term climate resilience.

Hesco Baskets

What is the Hesco Baskets Project?

During the 2021 Atmospheric River, many temporary flood mitigation works were put in place.

Among these were temporary riprap dikes, bank stabilization measures, and temporary Hesco baskets.

Many of the Hesco baskets were placed on private property during the flood. These baskets are designed for short term use, and thus after 3 years it is likely they are not providing the full protection as designed. The preference of the City is to keep these baskets in place until permanent diking solutions are funded and constructed.

However, given that they are on private property and there is no State of Local Emergency in place, the City is able to remove them at the landowners request.

These removals have been completed at some places already, and have been documented.

STUWI(x) Naturalization Project

What is the STUWI(x) Naturalization Project?

The STUWI(x) project, located at the confluence of the Coldwater and Nicola Rivers in Merritt, BC, is a transformative community-led initiative focused on restoring and reimagining a vital natural landscape while honoring Indigenous knowledge and stewardship.

At its core, STUWI(x) is about creating a dynamic partnership with representatives from all six valley bands and a community member from the City of Merritt to collaboratively restore the river confluence, which has been deeply impacted by colonization and urban development.

This project goes beyond simple restoration by prioritizing the integration of traditional ecological knowledge with contemporary science, ensuring that the restored area is not only resilient to future floods but also revitalizes the cultural and environmental significance of the rivers.

The plan includes acquiring properties in the floodplain, removing man-made structures, and rehabilitating the landscape to support natural processes and Indigenous land-use practices that have sustained the region for millennia.

With a focus on reconciliation and genuine collaboration, STUWI(x) empowers Indigenous voices in all phases of the project, from conceptual design to implementation.

The steering committee, composed of diverse community members, will lead the decision-making process, supported by engineers, ecologists, and knowledge holders. This approach ensures that the project reflects the aspirations and values of the local Indigenous communities while fostering an inclusive environment where all voices are heard.

The envisioned outcomes could range from creating naturalized floodplains and backchannels for salmon spawning to establishing flood-mitigation features that work harmoniously with the landscape.

Public access will be preserved, encouraging community engagement with the restored site. By weaving together Indigenous perspectives, ecological restoration, and flood management, STUWI(x) stands as a model for how communities can work together to build resilience, honour cultural heritage, and heal the land.

Who are the Engagement Participants?

The southern British Columbia interior and Nicola Valley are home to Nleʔkepmx and Syilx Nations and the City of Merritt resides within their traditional, ancestral and unceded territories.

The City is committed to engaging with all interested Communities, formally and informally on the STUWI(x) Naturalization project (as of September 24, 2024).

Voght Street Pump Station

What is the Voght Street Pump Station Project?

The Voght Street Pump Station is a crucial piece of infrastructure that will help manage stormwater during extreme weather events.

While dikes prevent river water from flooding into the city, they also create a barrier, preventing rain and stormwater from draining back into the river.

This new pump station will ensure efficient water flow, reducing the risk of localized flooding.

This City of Merritt pump station project will proceed once dike alignments are confirmed, and engineering work can begin.
