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) — One of the most controversial developments in San Diego's recent history is now welcoming its first residents.The One Paseo development has leased about 60 of its planned 608 housing units, most of which are still under construction.The complex aims to put everything within the reach of its residents in a live, work, play environment. The model units are even staged to make the most discriminating apartment shopper feel right at home. The fridge is stocked with sodas, candy, snacks, and even beer. "If you come here, it's like living on a vacation everyday," said Jay Rey-Hiplito, Kilroy's vice president. "We've got pools, we've got fitness centers, if you're into the best restaurants, you can walk right across the street."RELATED: One Paseo set to open in Carmel Valley following numerous setbacksOne Paseo packs 608 housing units into three buildings just south of Del Mar Heights Road. Rey-Hipolito says with San Diego's supply crunch, renters are willing to live in dense apartment complexes like One Paseo. He says they are increasingly looking at the housing units as places where they rest, spending their leisure time and entertaining at the amenities. The complex includes two pools (one saltwater), a community room, and an expansive gym. In all, that's why he believes the price is right for the units. Studios start at ,350 a month, and the model two-bedroom, at 1,058 square feet, goes for between ,600 and ,800 a month."Instead of looking at price, it's important to focus on value," Rey-Hiploito said. "When you're looking at what you get, you may no longer need to have a second car, you may not need to have a gym membership anymore."RELATED: City Council approves slimmed down One PaseoOne Paseo is a three-pronged, 0-million development that includes housing, office, and retail. The San Diego City Council approved a larger version in 2015, but nearby residents, and the owners of the mall across the street, led a referendum that ended with the current scaled down development. So far, 237 units are available. The development includes 61 affordable units for households earning up to 65 percent of the area median income. The full construction should be complete by the first quarter of 2020. 2259

SAN DIEGO (KGTV) - New plans for a development in the Bay Park neighborhood are aimed at providing "transit-oriented" homes amid the region's housing crunch.Protea Properties has plans for the 3.5-acre lot right off Interstate 5, between Clairemont Drive and Morena Boulevard. The site is located across from the future Blue Line Trolley Station.The development director of the project confirms the development includes 156 apartments and 40,000-square-feet of retail and restaurant spaces. Some community members are concerned with the current plans and tell 10News they hope their concerns will be heard and changes will be made. "We're trying to back the city off from slamming us with density and trying to get a project that meets everybody's needs," local James Lamattery said.Lamattery says the community is fighting for more affordable housing units and lower building heights. Right now, the plans call for two, four-story buildings and 16 apartment units for affordable housing. The city is reviewing plans before they vote on required permits. The development director says the earliest the project could be complete is 2022. 1145
