SAN DIEGO (KGTV) - Nearly 300 goats are munching away at brush on and around Cuyamaca College.The college contracted with Environmental Land Management and its goats to help with fire mitigation.A preserve surrounds the 165-acre campus. The goats and ELM staff and machinery will clear about 50 acres of brush in six to eight weeks. The goats are estimated to do 65 percent of the clearing work.Julianna Barnes, the President of Cuyamaca College, says the goats are a way to be pro-active during the fire season.“Usually we bring out an all-human crew with heavy machinery,” Barnes said, “but it’s actually 20 percent the cost of bringing in an all-human crew. And it’s more environmentally sound.”The goats will eat 7- to 10-percent of their body weight. Also, goats do not re-seed plant life in their excrement, according to the college.“We have a lot of non-native plants, and they’re highly flammable,” Barnes said, “(The goats) love to eat, and they love these non- native plants.” 994

SAN DIEGO (KGTV) -- Neighbors in Ocean Beach and Point Loma are hoping new surveillance video will help arson investigators find whomever is responsible for a series of fires over the weekend. The video was taken from a yard near one of the fires. It shows a man walking in and out of frame then moments later, neighbors say, another fire stared. The fires all happened early Saturday morning within hours and just miles of each other. Arson investigators are calling the fires suspicious , all of them started in people's backyards. San Diego Police tell 10News they're still working to find out if the fires are related and also looking at the surveillance video to find out if the man in the video is a suspect. Detectives ask that anyone else with video, turn it over to the department. 799

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) - Near Crystal Pier, an unusual sight greeted residents and beach visitors in North Pacific Beach: a multi-million dollar home spray-painted with graffiti. Feet from Palisades Park is an impressive home, perched on a bluff and boasting a pristine view. That home is now adorned with something not so pristine."Not good. It's an eyesore for the area. Spoils the whole look for the area," said Nick Tulip, a tourist from England.Neighbors say the large tagging appeared on the home over the weekend. "This kind of stuff I've never seen before, so I hope it won't be trending," said Elise Bernier, who lives in the area.Just to the south, along other parts of the shore, the sight of graffiti is more common, especially as school lets out for the summer. Neighbors in North Pacific beach are concerned that could be headed in their direction."It's an early sign of what's to come," said Ron Calkins, a retired firefighter who has seen tagging escalate in other areas."Other people are going to cross it off and put their own tags up. It turns into a stupid turf war between people that don't even live here ... just going to get worse unless there is more enforcement," said Calkins.The possibility that there is more to come is an uneasy feeling in an area known for tranquility."Totally disrupts the beauty of what's going on," said Bernier. 1365
