SAN DIEGO (KGTV) — Nearly three-quarters of the students in San Diego County are currently learning from home, and those numbers don’t make a lot of sense to MIT professor Martin Bazant.Bazant is one of the creators of the COVID-19 Indoor Safety Guideline. The free online tool simulates the fluid dynamics of respiratory droplets in various kinds of rooms to show users the risk of different indoor environments.“If you run the numbers for a typical classroom, especially if the students and the teachers are wearing masks, then the amount of time in the room can be very significant,” Bazant said. “Essentially those people could spend a week in the classroom and not have a problem.”Bazant says the six-foot rule that has largely determined which businesses can stay open is overly simplistic. In some cases, he says the rule creates a false sense of security. In other situations, he says it causes the closure of businesses or schools that could safely operate.“If you place nursing home beds six feet apart in a shared room, they are absolutely not safe,” he said. But he said well-ventilated classrooms, with teachers and students in masks, are another story.“It's only the United States where we follow the six-foot rule. That's given by the CDC. The World Health Organization all along has been saying one meter, which is about three feet. If you simply followed the one-meter rule, all our schools would be open, as they are in most of the world right now,” he said.Bazant and his colleague John Bush said they set out to design a tool that would reveal the risk of transmission based on science, not guesswork.Users start by selecting a room type, like a classroom or an airplane. From there, they can control a wide array of variables to dial in the risk, like the room size, the ceiling height, and the ventilation and filtration systems.From there, users can further tune the model by human behavior. How many people are in the room? Are they whispering, shouting or singing? How many are wearing masks?Mask usage is a critical component, Bazant says. The model quickly reveals the challenges of maskless activities in rooms with poor ventilation. Put five people without masks in a 400 square foot room with closed windows, and it becomes unsafe after 33 minutes.Bazant says studies on super spreader events show in indoor environments, the distance from an infected person doesn’t matter. Infected droplets spread and mix throughout the room like second-hand smoke from a cigarette.But with masks trapping droplets and diverting them upwards like a chimney, an environment like an airplane could be safe for several hours, according to the model. With more than 95% of the passengers and crew wearing surgical masks, a Boeing 737 could support 200 people -- around full capacity depending on the configuration -- for 18 hours. 2850

SAN DIEGO (KGTV) -- On July 3, visitors will once again be able to ignite their minds in the world of science and curiosity, as the exhibits at the Fleet Science center in Balboa Park will be open for exploration."We're very excited to welcome everyone back into our building," says Fleet Center Communications Manager Karla Nafarrate. "We just can't wait until the exhibit gets going, as well as the theater. We've missed everyone so much."The Fleet Science Center is a hands-on museum, and because of that, major safety precautions will be in place. That would include reduced capacity, visitors must wear face masks, and social distancing. Add to that, the entire museum will be sanitized before it's opening."The coolest part is that we have a sanitizer that cleans everything, and gets rid of any little bacteria. Anything that might be on any surface. it's kind of like a Ghostbuster machine."From exhibits like Kids City, to the Whisper Dishes, and Space Theater, it's time to get back to the knowledge and fun of learning about science."Not only the kids," says Nafarrate, "but also the kids at heart. Although we're a little more cautious about that right now, we still want to have a good experience."If your are planning on making a trip to the Fleet Science Center, they are encouraging you purchase tickets online. 1336

SAN DIEGO (KGTV) - One of San Diego's hottest restaurant groups is suing the City of San Diego, in part, for negligence. The owner of Little Italy’s The Crack Shack and Juniper & Ivy gave 10 News an exclusive interview regarding allegations that the city failed to remedy issues which led to last summer’s massive water main break that flooded much of the area. “It seems the city is using a ‘whack-a-mole’ approach,” says restaurant owner Michael Rosen when asked about the city’s way of addressing underground piping issues.  Rosen’s Juniper Hospitality restaurant group in suing the city for negligence, negligent interference with economic advantage and prospective economic advantage, and inverse condemnation. According to the recently filed lawsuit, before the July water main break, “…the defendants were working within the area and had left temporary water pipes above ground, which were being run over by hundreds of cars a day, for approximately six months with no further attempt to repair or remove…The Defendants issued a ‘quick fix’ to the problem in lieu of fixing the unstable water main which resulted in the massive rupture that occurred.” “This is what happens when you ignore a problem for so many months,” he tells 10 News. Rosen claims more than 400 reservations had to be canceled. “We likely lost 30 to 40 thousand dollars in revenue for the day and it was a very busy day,” he adds. “It’s just mind-boggling,” says Adam Babin of Power Keg Athletics. Babin’s CrossFit studio was destroyed beyond repair. He believes he lost more than 0,000 in property, alone. “Hands down, this was the toughest and most mentally and emotionally [difficult] situations I've ever had to deal with in my life,” he adds.  “It definitely hurt my business for sure,” says Rebecca Hyde-Edwards of Hyde Edwards Salon and Spa. Hyde-Edwards, Babin and Rosen say they have yet to receive adequate responses from the city after submitting their damage claims.  "This is a destination area and [the city] should look out for all the businesses that make it what it is,” adds Hyde-Edwards. A City of San Diego spokesperson tells 10News the city has received 28 claims and paid out .5 million to date. Only 3 of the 28 claims have been resolved. It reports that claimants have not submitted all of the supporting documentation, so not all claims have been paid. Timeframes for payments are reportedly done on a case by case basis and vary depending upon when all the supporting documentation is received and evaluated by the City.  The city’s aging water system infrastructure has wreaked havoc. More than 0 million have been spent in the last 5 years to repair and replace more than 100 miles of piping. Rosen tells 10News he’d be happy to drop his lawsuit if the city had a comprehensive plan to fix Little Italy’s crumbling piping. “It’s our expectation and justifiable fear that we'll have to close many days in the future unless this is really addressed,” he says of his restaurants.  A city spokesperson reports the broken section of pipe in Little Italy was immediately replaced after the flooding. The city’s 0.95 mile pipeline replacement project in that area was reportedly completed last summer. A spokesperson for the city says there are no additional plans for pipeline repairs or replacement for that immediate area.  The city will not respond to the lawsuit. It reports it doesn't comment on pending litigation.  Visit Group Job 954 for a closer look at the project being referenced in this story. The  CIP Project Map Viewer has the status of city projects in your area, which can be searched by address.    3797

SAN DIEGO (KGTV) - Poway residents are once again voicing displeasure with the owner of the now-closed Stoneridge Country Club. Thursday, crews from Big Trees Nursery began removing dozens of trees from the property."I couldn't believe it," neighbor Brian Edmonston told 10News. "I thought it was outrageous and it was a cruel thing to do."In 2017, owner Michael Schlesinger backed a ballot measure which would have allowed him to build more than 100 condos on the land.  The day after Poway voters rejected the plan, Schlesinger closed the club.Poway City Councilmember Barry Leonard told 10News that because the land is private property and the trees being removed are not "native trees", Schlesinger is within his rights to remove and sell the trees.Leonard also said that because Schlesinger terminated water service to the property, he would rather see the trees removed than die. 908
