Highway 36 Sinkhole Exposes Pressing Questions, Conflicting Answers

Highway 36 Sinkhole Exposes Pressing Questions, Conflicting Answers

Written by Luke Schmaltz

The sweltering months of 2019 were bumper-to-bumper trouble for U.S. Highway 36 commuters.

Questions Raised: Residents began to ask how long it would take to fix and who was going to pay for it?

If you are one of the 107,000 motorists or public transportation customers who traverse this corridor daily, here’s hoping your vehicle has air conditioning, your playlist is extensive, and your boss knows you’re going to be late.

A considerable crack in the surface layer appeared July 12, 2019, prompting Colorado Department of Transportation (CDOT) crews to close the eastbound lanes at Church Ranch Blvd. The decision was indeed prudent, as the fissure soon gave way to a gap that eventually ruptured into a ditch-like sinkhole in the road.

By July 15, 2019, traffic in both directions had been diverted to two respective lanes of the westbound corridor — resulting in a bottleneck effect in an already heavily congested zone. This allowed some traffic flow, however sluggish, so that CDOT crews could access the area, analyze the damage and embark on a massive repair project.

Meanwhile, the event sparked several issues, as area residents, CDOT personnel and daily commuters began to ponder the obvious. How long would it be before the damage was fixed, why had a new stretch of road caved in like the top of a half-baked cake, and perhaps most importantly, where would the money come from to pay for the reconstruction?

A Dubious Timeline

Lateral and aerial photos revealed a multi-dimensional calamity, as the horizontal depression in the road was countered by a vertical eruption of retaining wall concrete slabs, debris-ridden soil and mangled rebar. On July 15, 2019, CDOT chief engineer Josh Laipply was quoted by several news outlets including Colorado Public Radio (CPR) as stating that it would be “weeks” before the highway would be returned to an operational condition. Several days later, that statement was amended by CDOT Executive Director Shoshana Lew, who offered that it would be “a matter of months” for the repair to be completed.

Meanwhile CDOT Communications Director Matt Inzeo via phone interview declined to comment on a projected timeline. He pivoted instead and offered that the retaining wall-supported embankment upon which the highway was built sits next to a “wetlands area that used to be a lake.”

A Sinking Feeling

Crack In The Surface: A considerable crack in the surface layer appeared July 12, 2019, prompting Colorado Department of Transportation (CDOT) crews to close the eastbound lanes at Church Ranch Blvd.

The aforementioned information, perhaps inadvertently, placed a certain gravity on a statement issued by CDOT spokesperson Tamara Rollison, who explained “It appears water has gotten underneath the section that’s collapsing. It looks like it’s unraveling.”

At this point in the story, the term “collapsing soils” was introduced as a possible culprit. A blog published by CPR offered a statement from professor of construction engineering management at CU Boulder, Cristina Torres-Machi. It states: “[Torres-Machi] said it looks like a nearly textbook example of what she called ‘slope failure,’ essentially a landslide … She said it’s likely because of collapsing soils.”

Just in case (like most folks) you are not a geology major, collapsing soils are comprised of dry, low-density particles which can withstand significant impact without losing volume. Once water is introduced, however, the particles break apart, densify and undergo a significant reduction in volume. Oftentimes this results in the sudden appearance of a sinkhole.

In early August, a phone interview with Colorado Geological Survey Senior Engineering Geologist Jonathan White revealed contrary information that seemed to muddy the waters. Professor White explained that the embankment supporting the highway was comprised of “highly saturated, already wet soils” and the sinkhole was “most likely caused by a lateral landslide” and “was not the result of the presence of collapsing soils.” Professor White explained further that the wetlands adjacent to the highway were inherently responsible for the preliminary presence of moisture in the soil beneath the highway. He finished by stating that sudden influx of more water did not cause a collapsing soil situation and the disaster was more likely attributable to “an engineering issue.”

Who’s Going To Pay For This?

If Professor White is indeed correct, then upon whose shoulders gets foisted the blame? If it is neither the cause of collapsing soils or the effects of plain ol’ gravity, then by default, human error takes the spotlight. Regardless, the road must be repaired. A massive reconstruction project was launched as soon as engineers determined the debris and soil had ceased to shift and collapse.

This section of highway was completed just over five years ago in a joint venture between Granite Construction of California and Ames Construction of Aurora. By all estimations, it should most certainly not be crumbling, yet until engineering failure on the behalf of the contractors is found to be the cause, other monies have been allocated to pay for the reconstruction.

With Colorado’s massive influx of marijuana-based tax revenue, it is clear the $20.4 million repair and reimbursement estimate should be easy to meet by this revenue stream alone. After all, in 2019 alone, total tax revenue is projected by the Colorado Department of Revenue to be somewhere around the $30 million mark. Some experts believe it stands to reason that coffers swelling with monetary influx that was virtually nonexistent when that section of the road was built should rightly be tapped to remedy its untimely demise. Yet, when pressed for information on where the “contingency funds” allocated by the State Transportation Commission were being siphoned from, representatives of CDOT, Colorado Department of Revenue and Colorado Department of the Treasury declined to elaborate. A representative of the latter (who refused to be named) offered only the tersely toned retort “… well, first of all, treasury is not revenue.” Whatever that is supposed to mean, it sounds about as solid as collapsing soil.

Cirque du Solei’s Corteo Coming To Pepsi Center August 15

Cirque du Solei’s Corteo Coming To Pepsi Center August 15

by Mark Smiley

The latest Cirque du Solei show to come to Denver is Corteo, written and directed by Daniele Finzi Pasca. Corteo, which has been seen by eight million people around the world, tells the story of a clown picturing his own funeral, which takes place at a carnival and is witnessed by angels. Corteo, which means “cortege” in Italian, is a joyous procession, a festive parade imagined by a clown.

Bouncing Beds: Like a gaggle of young kids playing in their grandparents’ room, six artists jump on two 600-pound beds that move on rotating platforms.

The show first premiered in 2005 under the big top in Montreal and has been since updated for arenas in March 2018, keeping the original story intact. The show features 51 performers, including acrobats, clowns, musicians and actors.

Cirque du Solei has been entertaining Colorado audiences since 1997. “We always have a great responsive audience there and we love to perform in a place where people react well and enjoy our shows and I think it adds a lot to the show,” said Max Batista, Tour Publicist for Cirque Corteo.

The stage has a unique setup as it will be set up in the center of the arena and audience members will be on either side with good sight views. Set Designer Jean Rabasse has divided the Grand Chapiteau and its rotating stage in two, with each half of the audience facing the other half, so they see not only the performance, but also have a performer’s eye view of the audience. There is one turntable built into the stage, which is about 41 feet long, and the track is almost 120 feet long.

This show also features six musicians and two singers who are on stage with the performers. Typically, musicians and singers are hidden from the audience but in Corteo, they are part of the show. “People can see us all during the show,” said Eve Willems who plays the accordion, guitar, and mandolin in Corteo.

Corteo: In this Cirque du Soleil a clown imagines his own funeral as a carnival of sorts, blending the ridiculous with the tragic. The show will be performed nine times from August 15 to August 22 at Pepsi Center.

The music accompanies the show and features different styles of music including Spanish and Irish. Willems, who submitted her video application to become a part of the show via Facebook, enjoys being part of Cirque. “At first for me it was to discover all the different talents and I was amazed to see all these people doing their tricks,” said Willems. “Now that we have started, I like traveling with all these people and make people dream and it’s really nice to be part of it.”

The show lasts two hours and 30 minutes  (with a 20-minute intermission) and is packed with death defying feats fans have come to expect from Cirque shows.

Cirque du Solei’s Corteo arrives at the Pepsi Center on August 15, 2019, and runs through August 22, 2019. For tickets, visit www.cirquedusoleil.com/usa/denver/corteo/buy-tickets.

Governor Rocks HOA World With Veto

Governor Rocks HOA World With Veto

As Licensing Disappears For Property Managers, HOA Issues Rise To The Fore

by Ruthy Wexler

Everyone thought HB 1212 would pass.

What House Bill 19-1212 did was reinstate the licensing program for Community Association Managers (CAMs), which was set to expire July 1, 2019. The bill extended CAM licensing for just one year, during which time stakeholders were charged with exploring the issue.

Surprising Veto: Governor Jared Polis’s (pictured with Lt. Governor Dianne Primavera) veto of HB 1212 surprised legislators, management companies, homeowners and HOA activists, leaving them all to wonder whether this Governor will be approaching the HOA situation as fearlessly and creatively as he has approached education, health care and health costs. The upcoming stakeholder meetings regarding CAM licensing and HOA issues, in August, September and October, will reveal how deep the conversation about HOAs will go.

As legislators put HB 1212 together, the usual suspects tried to shape it. Homeowner advocate Stan Hrincevich, pleaded for the inclusion of additional homeowner protections; e.g., ensuring managers document and disclose fees; while the Colorado Legislative Action Committee — legal arm of CAI (Community Association Institute), an international lobby representing management companies, property managers, HOA attorneys and other benefiting vendors — fought to keep such regulatory measures out.

The bill’s sponsors — Representatives Monica Duran and Brianna Titone, Senators Nancy Todd and Rhonda Fields — ended up incorporating most of CAI’s requests, but none from Hrincevich, who voiced disappointment but also relief that “CAM licensing would be kept alive.” The bill passed the Assembly and Senate.

Then on May 31, Governor Jared Polis vetoed HB 1212. Ever since, the Colorado HOA world has been trying to understand what lies ahead.

What’s The Big Deal?

In his two-page veto letter, Polis expressed concerns over “occupational licensing” — the subject of three of the five bills he’d vetoed (out of 460 passed). Such licensing, he said, might “… prevent minorities and the economically disadvantaged from … access[ing] occupations.”

Polis’s concerns, many feel, had little to do with CAM licensing, an issue one homeowner described as the “tip of an iceberg with huge dangerous issues below everyone is afraid to fight.”

“Here’s the essence,” says Hrincevich. “The HOA Property Manager Licensing law was the only path homeowners had to address wrongdoing on the part of a manager.”

Colorado homeowners had no recourse at all — short of going to court, which was too costly and intimidating to be a real option — until 2015, when Colorado passed a law that regulated HOA property managers. Individuals had to pass background checks, get certified, pay a fee and pass an exam, in order to earn a CAM license.

At that point, if a homeowner believed their property manager was behaving illegally, they could file a complaint, citing their CAM’s license number, with the Real Estate Division inside DORA, which had awarded that CAM license — and could take it away.

The process was slow, the results not always to the homeowner’s liking, but, says homeowner and retired financial analyst Barb DeHart, “It allowed homeowners not to feel entirely helpless.”

All Counties Heard From

Post Polis’s veto, reactions varied widely. Legislators, believing they’d done what was necessary to pass the bill, felt betrayed. “I was completely shocked,” said Duran. “Greatly disappointed. The work we’d done to protect homeowners … has been undone.”

HOA homeowners who had been following this issue felt betrayed also, and afraid. “It’s bad enough with [CAM] licensing,” wrote P., a Denver homeowner fearing reprisal from her property manager. “What will [name of manager] do with no oversight at all??”

 “As of July 1,” said HOA activist Andrea Antico. “management companies … can do anything they want.”

Realtors were appalled. Live Urban Real Estate listed possible “outcomes of this loss of consumer protection.” Linda Chapman, realtor for over 35 years, called the veto “unconscionable.” She explained, “Management companies and property managers handle millions and millions of dollars of other people’s money. All other industries performing fiduciary duties are required to be licensed and regulated. Except CAMs.”

HOA attorneys appeared lighthearted. “Community association manager licensing is no more!” wrote Elina Gilbert of Altitude Law, in a blog titled, Why Oh Why Did Manager Licensing Die? One HOA attorney described colleagues as “… happily anticipating lots of business …”

One community manager, Sue McClure, said the veto felt like a “slap in the face to those of us that have made the effort to … be professional,” while another, Joe Felice, said he agreed with the Governor. “I don’t believe licensing helped homeowners or associations in any substantive way. … “

Property manager Alec Hrynevich, of Accord Management, said, “I’m not opposed to licensing. But it doesn’t do in this case what it’s supposed to do.”

More than a few managers and homeowners agreed that abuses within HOAs would not necessarily have been prevented if CAM licensing was in effect.

Change The Conversation

The HOA Office releases a report each year that summarizes the complaints they’ve received from homeowners. In 2018, high on the list was management companies and property managers not following their HOA’s governing documents; close behind were poor manager communication, selective enforcement of covenants and failure to produce records, required under Colorado HOA law.

Testify: CAI member Brandon Helm testifies in front of the Colorado House Finance Committee in support of HB1212, the “pre-amended” form of the bill that CAI called, “the version we support.” For many years, the CAI Colorado Legislative Action Committee told legislators they represented the entire HOA community. Homeowners comprise only 2% of CAI membership.

Accompanying Polis’s veto was an Executive Order, number D 2019 006, directing DORA to “lead a … comprehensive review of CAMs and HOAs.” Many homeowners felt excited at the prospect of an open conversation about HOAs.

Since Polis took office, he’s made it clear how hard he will push for issues he is passionate about, like education and health care. He has not made it clear if HOA reform is one of those issues, although Hrincevich noted, “Leaving out further consumer protections [in HB 1212] is what Polis seemed mostly to object to.”

 What CAI appears to mostly object to is regulation within HOAs. A map on their website resembles a campaign war room, blue outlining the few states with CAM licensing; click on each state and see what stage the legal battle around that issue has reached. “Stay up to date on CAM licensing and its impact on associations,” encourages CAI Senior Vice President Dawn Bauman.

“With the veto of HB 19-1212,” states Polis in his Executive Order, “the State has an opportunity to change the conversation about … CAMs and HOAs.” As per that order, stakeholder meetings will be held on August 14 and 29, September 12 and October 8 at the DORA offices. Registration is open.

Never Let Hate Take Root In Your Heart

Never Let Hate Take Root In Your Heart

Holocaust Survivor Shares Memories And Advice

by Ruthy Wexler

Wall Of Love: Jack Welner points to a photo of Lori Goldberg, his special friend. All around him is his “wall of love,” photos of children, grandchildren and great-grandchildren, evidence that — despite his grievous losses — Welner stayed open to life and love. His advice to people: “Don’t let your past ruin your future. Live life to the fullest.”

At 98, Jack Welner’s face shines with the eager ebullience of a 6-year-old. His eyes twinkle with fun. That’s the kind of boy Welner was back in Lodz, Poland — helpful, fun-loving, excited about life — and by all accounts, that’s the kind of man he became. In between, however, came the Holocaust, and — because Welner is Jewish — unimaginable suffering.

Through Auschwitz, Dachau, labor camps, a death march — how, people ask, did you stay the same person? Looking back over the years, Welner explains how he kept bitterness out of his heart and held onto the twinkle in his eye.

Take This, You’ll Need It

Death Camp: The Auschwitz death camp was a complex of over 40 concentration and extermination camps built and operated by Nazi Germany in occupied Poland during World War II and the Holocaust. Jack Welner arrived at Auschwitz in 1944.

It’s not that Welner forgot what happened. He shares memories so vivid, you are there: watching how fast the Germans turn a corner of Lodz into a barbed wire ghetto; seeing guards shoot Jews in the ghetto streets “just for practice”; pretending — along with the seven other family members crammed into one room with no toilet or running water — that the beet leaves your mother salted and fried taste just like herring.

“We were starving [in the ghetto],” recalls Welner. “Just before we got on the train [for Auschwitz], we got a little piece of bread. Late that night, we arrived. I helped mother down from the train. She still had her bread. She pushed it into my hand. ‘Here. Take this. You’ll need it.’”

Welner’s eyes fill with tears. “Those were the last words my mother said to me.”

Look For Luck

After the war, when Welner was in a safer place — Denver, CO! — and heard “even a little bit of antisemitism” he’d speak up. “I left Poland to get rid of SOBs like you, so you better shut up.”

“Later,” he adds, “we’d become friends.”

Young Boy: Thirteen-year-old Jacob Welniarz, who became Jack Welner in America, poses for a photo in his boyhood city of Lodz, Poland. He had no idea that in six years, his family would be torn apart and he would be sent to the Auschwitz death camp.

But back when hatred of Jews was law, Welner searched for small ways to survive. In a labor camp near Dachau, a guard kept beating Welner with a 2×4 so brutally, “I knew I would die if he kept it up … so I sank to the ground and began crying. Not so much from pain, but I had to … do something.”

Welner adds emphatically: “In my mind, I was saying, ‘I will survive you, you SOB!’”

Later on in that camp, “… my luck changed. A machine operator took a liking to me. I was suffering from an ulcer. He let me lie down. He brought me rinds of bread to eat.

“He saved my life,” concludes Welner, who, after the war, traveled twice to Munich to bring food to that guard.

Welner was still able to feel empathy.

Many had lost that capacity.

“I had a cousin, blonde, she survived by working as a maid in a Warsaw hotel, disguised as a Christian,” Welner recalls. “When the [Warsaw] ghetto was burning, someone laughed, ‘Look, the bedbugs are frying.’ Her family was inside that ghetto and she had to stand there, crying, saying nothing …”

Welner shakes his head. He tells how, upon arriving back in Lodz after being liberated, the first words he heard from a Christian were, “Oh, a lot of you Jews are still alive.”

 L’Chaim (To Life)

Welner shares such memories seriously, like one delivering a valuable package. Now one more person knows and will not forget. But he is not inclined to dwell on or analyze the horror. Asked about antisemitism, Welner shrugs. “That’s how it was. Always the Jew was the scapegoat.”

When the subject turns, however, to his three children, six grandchildren and four great-grandchildren, Welner’s face lights up like a 100-candle birthday cake. He enthuses at length about each one. It glows when he converses about travel or music. And when he sings.

Welner loves to sing.

Quilt: So moved by Welner’s visit and what he shared about his experience during the Holocaust, one school decided to make Welner a quilt. Each child created a square in the quilt that shows what they got from hearing Welner speak.

 “I love Italian,” he rhapsodizes. “I still remember songs from Italy [where he was in a DP camp].”

In the ghetto, Welner recalls, there was a Jewish composer who wrote satiric songs. Welner sings one in Yiddish, then translates: “Such a disaster, you have to eat every day, the stomach always wants more and more…

“We needed to laugh,” he recalls.

Welner adores jokes. Laughing uproariously (but never ruining the punch line), Welner tells a joke about the cow from Minsk. The farmer and the bull. The one where two friends enter a bakery: “‘Moishe, look at that wonderful bagel!’ ‘Oh, but it’s got a big hole in the middle!”’

Optimist

“I see the bagel, not the hole,” Welner explains. “I’m an optimist.”

At 31, Welner anticipated a happy future when he met a beautiful girl, Adele. They married and moved to Denver. Seven years later, Adele died, leaving Welner with three small children and a broken heart.

Welner moved to Israel for five years to be near his sisters, then back to Denver, where he worked as a carpenter and raised his kids. Despite the disappointment of a subsequent marriage not working out, “My father always enjoyed life,” recalls Welner’s daughter Beverly. “Our home was filled with love and laughter.”

As a Holocaust Survivor, Welner spoke to schools and groups in Denver and surrounding areas. Then in 1995, the Shoah Foundation sent Lori Goldberg to interview Welner.      

The two connected.

“We became best friends, sharing life’s joys and challenges,” says Goldberg, who, coincidentally, in the first years of their relationship, saw Welner on Tuesdays.

“He was my Morrie,” she says, alluding to the book, Tuesdays with Morrie. “From Jack, I learned about courage, resiliency, hope, and love.”

My Motto

“Jack has taught me, no matter how difficult life can be, one should never give up hope, one should never stop loving,” said Goldberg.

“My motto,” Welner says, “is, ‘Don’t let the past ruin your future. If you live in the past, you don’t have a future.’”         

“I receive so much more from Jack than I could ever give,” says Welner’s caregiver, Linda Chambers. “It is an honor to know him. He will not allow hate to grow in his heart.”

Denver Built ‘Baby Boom’ To Propel Planet Into Supersonic Era

Denver Built ‘Baby Boom’ To Propel Planet Into Supersonic Era

Planned 2019 Test Flight To Hit Speeds Of 1,688 MPH;

Denver Co-Founders Raise $150 Million For Start-Up Firm


Future Boom Operator: Japan Airlines has invested $10 million in Boom and was given a special tour of the Denver headquarters. The airline has pre-ordered 20 aircraft and got a peek at the XB-1.

The XB-1 aircraft dubbed Baby Boom — a one-third-scale supersonic demonstrator — being built by Denver-based Boom Supersonic plans its first test flight later this year. Designed to reach speeds of up to 1,688 miles per hour or twice the speed of sound, it is the prototype for a commercial 55-passenger plane with a range of 5,180 miles to be introduced by 2023.

Co-founded by Denverites Blake Scholl and Josh Krall in 2014, the firm had raised $151 million by January of this year. Among the startup investors were several venture funds that kicked in $33 million in March 2017. In December 2017 Japan Airlines invested another $10 million, enough to build the XB-1 “Baby Boom.” Then in January Boom Supersonic was given another $100 million by Apple founder Steve Jobs’ widow Laurene Powell Jobs.


Supersonic Building Boom: Co-founded by Denverites Blake Scholl and Josh Krall in 2014, Boom Supersonic plans a test flight of the XB-1 aircraft dubbed Baby Boom this year.

Comfortably Close: The 55-seat plane named the Boom Overture will be able to fly from New York to London, Paris to Montreal, and Madrid to Boston in under four hours or less than half the time of conventional jets.

Boom says its aircraft — with a price estimate of $200 million — will produce a sonic boom at least 30 times quieter than the Concorde, which was also dogged by high operating costs and fuel consumption plus low capacity utilization. Boom estimates that fares for its aircraft will be 75% lower than the Concorde and comparable to current business class tickets, due to better fuel efficiency.

Pre-Orders Booming

Boom has 76 pre-orders for the 55-seat plane. The first commercial airline to back the venture with investments was British airline Virgin Atlantic that has options for 10 of the new aircraft. They made the deal 14 years after the final flight of the Concorde. In addition Japan Airlines has the option to purchase up to 20 Boom aircraft and will assist efforts to hone the aircraft’s design and passenger experience, according to the companies.

Called the Boom Overture, the 55-seat plane will be able to fly from New York to London, Paris to Montreal, and Madrid to Boston in under four hours — less than half the time of conventional jets. Although the plane will have fewer than half the seats of a Concorde, company officials say it will have a much better range — a staggering 5,180 miles.

The supersonic jet will also be more economical, and its sonic boom will be “at least 30 times quieter” than Concorde, the company claims. They also say that when it comes to landing and take-off: “Overture will be as quiet as the subsonic aircraft flying similar routes today.”

Mach 2.2 Speed

The firm says its jetliner — expected to enter service by the mid 2020s — will fly at speeds of Mach 2.2, 10% faster than the British-French joint venture Concorde, which popularized supersonic jet travel in the 1970s.

With 500 viable routes, there could be a market for 1,000 supersonic airliners with business class fares. It expects to keep the delta wing configuration of the Concorde but would be built with composite materials. It would be powered by three dry 15,000 20,000 lbf (67-89 kN) turbofans; a derivative or a clean sheet design will be selected in 2019.

General Electric Co., Honeywell International Inc. and Netherlands-based TenCate Advanced Composites are among suppliers for the Denver firm’s supersonic jets.

Accessible Planet

The Denver-based company was founded for the express purpose of making our planet dramatically more accessible. “We are taking proven science and engineering and using it to build a Mach-2.2 airliner that will kick off the supersonic era. And we are making the company a place where the best people on the planet can be inspired and enabled to do the best and most meaningful work of their careers,” says Founder-CEO Blake Scholl.


Blake’s Baby: Making high-speed travel mainstream is why Blake Scholl, who lives in Denver and is the father of three, founded Boom Supersonic.

Speed isn’t about going really fast Scholl says, “It’s about closeness. It’s about making far-away places feel like they’re right around the corner.” His point: Some people say that speed makes the world smaller. But at Mach 2.2, the planet is as big as ever. Life is bigger when it is experienced in person — with supersonic speeds, we’ll all experience a bigger world than ever before.

Over long distances people don’t think in miles and kilometers. They think in hours,” the CEO clarifies. He explains it this way: Crossing the U.S. takes about five hours. Going from New York to Dubai takes about 14. Speed isn’t about going really fast. It’s about closeness. It’s about making far away places feel like they’re right around the corner. If we can fly twice as fast, the world becomes twice as small, turning far off lands into familiar neighbors.

Founding Trio

Making high-speed travel mainstream is exactly why Scholl who lives in Denver and is the father of three founded Boom Supersonic. With a BS in Computer Science from Carnegie Mellon, he has held leadership roles at Amazon and Groupon and co-founded mobile technology startup Kima Labs that was acquired by Groupon in 2012.


Engineering Change: The first go of Boom Supersonic’s XB-1 engines on a U.S. Air Force Academy test cell ran to 95% of power.
