These environment stories from 2018 could give us hope

By

Climate science reports released in 2018 all pointed to impending catastrophes unless humankind can pull off some miraculous reversal of climatological trends and its own bad behavior.

In just the last year, huge wildfires raged out of control, Antarctica lost three trillion more tonnes of ice, extreme heat waves warned of an eventual Hothouse Earth by 2040 and droughts and intense storms have become commonplace. Climate change could even cause a global beer shortage.

But not all the environment news in 2018 was depressing. There was good news to savor, some of it originating right here at home.

Comox Valley

The Comox Valley Lands Trust is purchasing a 55-acre parcel at the top of Morrison Creek, and announced plans to eventually acquire and conserve the waterway’s entire 550-acre headwaters. This is important for a variety of reasons: Morrison Creek has lively and thriving aquatic life, including several salmon species, it feeds the Puntledge River and the K’omoks Estuary and it’s the only stream in the valley whose headwaters remain intact (undeveloped) and pristine.

The Cumberland Forest Society is currently negotiating to preserve another 93 hectares (230 acres) of the Cumberland Forest, mostly wetlands and key riparian areas along Perseverance Creek. Since it formed in 2000, the society has conserved 110 hectares (271 acres).

On Dec. 19, the Comox Valley Lands Trust announced that Father Charles Brandt had signed a covenant to conserve his 27-acre Hermitage on the Oyster River. The covenant means the property “will be protected in perpetuity for the benefit of all things wild.” Brandt has told Decafnation he intends to donate his property to the Comox Valley Regional District as an undeveloped public park.

In a process mired in missteps and lawsuits, the CVRD finally denied an application by the 3L Development company that would have created more urban sprawl, increased long-term infrastructure liabilities for taxpayers and despoiled a critical area. But an outstanding lawsuit means this story isn’t over.

The Partnership for Water Sustainability in BC and the Brooklyn Creek Watershed Society completed an Ecological Accounting Process document, which shows the value of the waterway to the Town of Comox for stormwater conveyance. It’s the first EAP in BC on a creek flowing through multiple jurisdictions, and shows how all stakeholders must have a common goal in order to prevent the death of another fish-bearing stream.

Many of the candidates who sought public office this fall — and most who were elected — endorsed the passage of new development policies that permit and encourage infill development. This is important to minimize urban sprawl, and maximize utilization of existing infrastructure, thus preserving more rural areas and natural ecological systems.

Thanks to Breathe Clean Air Comox Valley, more people know the serious health hazards of poor air quality caused by particulates in smoke from wood burning devices. And local governments are responding with bands on wood burning devices in new homes and incentives to eliminate or upgrade existing ones.

The sad sight of a mother orca carrying a dead calf around for weeks, as if to show humans what tragedies they are inflicting on the Earth’s other inhabitants, has sparked some positive change. Just not in BC, yet. Gov. Jay Inslee struck a task force that has recommended steps for orca recovery and the governor has earmarked over a billion dollars for the plan, which includes a ban on whale-watching tourism.

British Columbians got a sniff last summer of what climate change means for our future. One of the worst wildfire summers blanketed the south coast with smoke, haze and hazardous air quality. And with summers getting hotter and drier (it’s not just your imagination), wildfires will increase. It’s another step — albeit an unfortunate one — to wider spread public acknowledgement of climate change and the urgency of initiatives to maintain and improve our air quality.

The NDP government adopted a climate action plan this year calls for more electric vehicles and charging stations, requires all new buildings to be net-zero energy ready by 2032, diverts organic waste and other recyclables from landfills, while boosting the carbon tax and producing more hydroelectric power. It’s been criticized as being “just talk” and not going far enough, but the plan at least provides a blueprint for future climate action policies provincially and federally.

Global

Green energy is on the rise around the world. We had the largest annual increase in global renewable generation capacity in 2017 (most recent data), accounting for 70 percent of all additions to global power capacity. New solar photovoltaic capacity outsripped additions in coal, natural gas and nuclear power combined. As of 2016, renewable energy accounted for 18.2 percent of global total final energy consumption (most recent data), and modern renewables representing 10.4 percent.

The Organization for Economic Cooperation and Development thinks that global economic growth has peaked. They worry about the slowdown, but it’s good news for the planet. That’s the view of the new Degrowth movement, a theory that first world countries should plan for economic contraction in order to achieve a just and sustainable world.

Carbon emissions are declining, according to BP’s statistical review of world energy. Ukraine showed the greatest decline in 2017 of around 10 percent, due to dramatic reduction in coal usage. Unfortunately, Canada was one of the worst nations (22nd). Canada actually increased emissions by 3.4 percent, contributing the ninth largest share of carbon dioxide into the atmosphere behind China, the US and Japan.

Community-based renewable energy projects lead the way in reducing greenhouse gases both in Canada and around the world. Scotland’s Community and Renewable Energy Scheme (CARES) provides communities, businesses and other organizations advice and funding to create local and community energy projects. And, even the province of Alberta has a Community Generation Program for small-scale ventures into wind, biomass, hydro and solar.

And here’s a video that shows more reasons for hope. The question is, are we moving fast enough? And what more could we do?

Courtenay’s controversial Sixth Street Bridge: Whose idea was it?

The idea for a pedestrian and cycling bridge at Sixth Street originated about 40 years ago and followed a roller coaster ride to completion. It might have never been built without the persuasive pleading from Downtown businesses in 2019. An effusive thumbs up from mayoral candidate Manno Theos might have helped, too.

Will Manno Theos win Courtenay in vote split? And are these candidates using AI?

What’s going on in this year’s local government elections? More candidates. More women candidates. Another possible vote split in Courtenay to favor the underdog. Many long-time veterans still hanging on. Fake social media posters and other trolls. And suspicions surfacing of plagiarism or AI use in candidate statements. Looks like a wild four-week ride. Buckle up!

Overwhelmed by so many candidates? Just vote for the ones you know and like

For many Valley residents, it’s difficult and time consuming to gather the necessary information to make thoughtful selections in municipal elections. And paid trolls and fake posters on social media pages make it even more difficult. Public candidate forums help, but there is a simple solution for frustrated voters

“Liberal Rush” tricked voters in NDP ridings and exposed an electoral system flaw

Despite the positive big picture outcome, this election exposed a glaring vulnerability within our electoral system. And that vulnerability caused otherwise smart people to forget how our Canadian parliamentary system actually works. Namely: We do not have a proportional representation form of government. But there is a simple solution.

No boil-water advisories in Cumberland

No boil-water advisories in Cumberland

While Courtenay and Comox residents suffer through another boil-water advisory this week, clear and drinkable water flows freely in the Village of Cumberland.

For Cumberland Mayor Leslie Baird that fact alone justifies her council’s decision to not join the Courtenay-Comox water system. But she also likes to point out that the village will save millions of dollars for its taxpayers.

Because while those other Comox Valley elected officials search for the financing to build a $110 million water filtration plant, Cumberland has already received a $4.9 million grant to fund the $6 million first stage of its long-term water quality and supply system improvement plan.

Joining the Courtenay-Comox system would have cost Cumberland taxpayers $26.7 million upfront and annual operating costs of $600,000.

Bringing their own system up to current provincial standards will cost $6 million now (80 percent funded by the provincial Clean Water, Wastewater fund), another $6.5 million for further improvements through 2066, and annual operating costs of $255,000.

It was a clear-cut financial decision, Mayor Baird said, and it provides the village with water security for the next 50 years.

How the water system works

Cumberland Manager of Operations Rob Crisfield said the village’s water supply comes from five lakes in two separate watersheds — Allen Lake in the Perseverance Creek watershed, and Hamilton, Stevens and Henderson lakes and Pond. No. 2 in the Cumberland Creek watershed.

The five lakes in two watersheds that comprise the Cumberland water supply. The village has a license for future use of Vanwest Lakes.

A deep well drilled in Coal Creek Historic Park opened in 2013. It adds a groundwater supply to the watersheds’ surface water sources.

The system operates on nine water licenses, some issued as early as 1897, and serves Cumberland and everyone in the Royston water service area. The village owns all of the land around the lakes, but not all of the land in the watersheds.

That means the system is less susceptible to harmful logging practices in terms of the turbidity issue that plagues the Courtenay-Comox system. Cumberland has not issued any boil-water advisories.

However, some of the infrastructure in the hills above the village is more than 100 years old. While it’s been maintained well, many upgrades are necessary and underway.

Henderson Lake has the lowest elevation of the four lakes in the Cumberland Creek watershed, so its outflow makes the connection to the village’s water supply. It merges with a line from Allen Lake.

Where water lines from the two watersheds come together, the water is treated with chlorine. It then descends down to Cumberland via a single, one kilometer long 300 mm diameter pipe, before splitting again into two main trunk lines servicing different parts of the village.

What’s happening now

The village is installing a second “twinned” 300 mm pipe so it can regulate the flow from each watershed based on the amount of water stored in the lakes. That work should finish in mid-December.

Future work will include adding a new facility that will provides both UV and chlorine treatment. It will also switch from chlorine gas to sodium hypochlorite, which poses fewer risks for operators.

The village will also construct two new reservoirs to increase water storage capacity. One will go out to tender in the spring, along with the new UV treatment facility. The second reservoir will be built by the year 2040.

Sediment washing into Comox Lake through Perseverance Creek after a major rain event in 2014

Crisfield said the village will repair and replace some of its dams, most importantly the Pond No. 2 dam, which failed in December of 1972, causing a washout of the Henderson Lake dam. Both the Henderson dam and No. 2 dam were rebuilt in 1973, with a spillway out of Cumberland Creek watershed and into Perseverance Creek.

It was this spillway that undercut a kilometer-long 50-foot high bank during a major rain event in 2014. The ensuing slide washed sentiment, including clay particles, into Perseverance Creek and ultimately into Comox Lake, the source of drinking water for Courtenay and Comox. Following the slide, a the Comox Valley Regional District issued a boil-water advisory for Courtenay-Comox residents that lasted 49 days.

Crisfield said other dams will get either seismic stabilization, such as Stevens Lake did in 2014, or be completely rebuilt over time to meet the Canadian Dam Safety Guidelines in future years.

How residents benefit

When all the projects are completed, Cumberland and Royston will have a secure supply of water through 2066 that meets B.C. Drinking Water Guidelines. The more reliable and controllable system will reduce risks to human life, the water supply and the environment from a major earthquake.

The village was able to lift its moratorium on development in 2014 after opening the Coal Creek deep groundwater well.

It will surprise some that Cumberland is the fastest growing community in the Comox Valley. According to the 2016 Census statistics, the village grew by 5.6 percent to 3,600 residents. That beats Courtenay, Comox and all three regional districts, which each grew by 4.7 percent.

It’s even more surprising that during that same period of growth, Cumberland has reduced its demand for water by 41 percent, according to the June 2016 study by Koers & Associates Engineering Ltd. Cumberland residents used 49 percent less water and Royston residents used 17 percent less.

The lower water usage resulted from a new rate structure and the installation of water meters at all residential and commercial connections. People just naturally used less water. And the meters revealed many service leaks, which have been repaired.

Crisfield said once all these surface supply improvements are in place, Cumberland will have improved redundancy and reliability on water delivery, improved water quality and greater flexibility in how they can operate the supply system.

What’s next
  • The biggest challenge confronting Cumberland is how to rebuild the Pond No. 2 dam; specifically where to direct its spillway. If it goes toward Cumberland Creek, it could affect water quality in the village’s system. If it goes into Perseverance Creek, it could erode more sediment into Comox Lake. Crisfield hopes that a study underway by Tetra Tech consulting engineers, of Nanaimo, will find a solution to that problem.
  • Meanwhile, Crisfield is interested in the possibility of generating hydroelectricity by adding turbines into the system’s water lines. Due to the large elevation drop, there may be sufficient pressure to power the water treatment operations.
