SAN DIEGO (KGTV) — Empty school busses belonging to the San Diego Unified School District are being driven around even though most students continue virtual learning.While this happens, San Diego Unified sits in Phase One of its reopening plan — meaning many students are still at home. Erin Coller's 5-year-old is in the school district. Right now he's learning from home but Coller says she seen busses in the neighborhood."Every time I see one of those busses I just think who is riding them - where could they possibly be going," says Coller. "It stopped at our house around the time that it used to come to our house and I was loading the kids in the car and I was like are you and angel can you just take them and drive them around please, what are you doing and he was just driving the route."At the end of October, Team 10 followed school busses on several days to see where they're going and what they're doing. After leaving the bus yard in Kearny Mesa, one bus headed north to the Scripps Ranch area. The bus made several stops like it was following a planned route, but no students ever got on or off. About 90 minutes and 31 miles later, the bus was back at the yard.Another bus left the yard later that same afternoon and headed to a school in the Poway area. It picked up one student and then headed south to drop them off.The next week, another bus bus went from the yard to Interstate 805 south. It continued on to State Route 54 east to then over to SR-125 north. The bus then completed the circle on SR-52 west. About 40 miles and 53 minutes later, the bus was back in the yard. It never stopped.Standing outside the school lot, bus movement is constant. SDUSD says for good reason."Just starting them up and running them in the parking lot for 10 minutes is not sufficient. They need to put on several miles to make sure that that transmission is maintained that fluids are at the right levels that seals and gaskets are all working also to make sure that our batteries are all charged," says Marceline Marques, SDUSD's operations support officer.Marques oversees the district's transportation."During a regular school year, you would see busses operating empty. I think it just stands out right now because most of our students are participating in online learning," Marques said.Part of that time on the road is driver proficiency. Right now, along with honing their skills, drivers are doing everything from delivering textbooks, to educational supplies, and computers to students' homes.They are evaluating stops for safety and space with social distancing requirements and evaluating school drop-off areas for physical distancing needs and adjustments among other things. The list of driver responsibilities goes on."If it's diesel it needs to be run or it can have problems but as far as delivering supplies I'm shocked to hear that they are doing that because we have multiple students at our school who can not come pick up supplies," one parent told Team 10.The district says it pays .83 per gallon for renewable diesel. Busses average about seven miles per gallon. So that first 30-mile trip we watched cost a little less than in gas. The bus that didn't stop, about .50 for that trip."I think that the practice of running our buses far outweighs the cost of the fuel or the concern that folks have when they see it running without a passenger," Marques said.Right now, about 150 busses are transporting students. Others are being used to help in other ways and some like we saw are rotating through that maintenance schedule. The district says overall, it needs to be ready for the next phases in reopening. 3654

SAN DIEGO (KGTV) - Every home in the city of San Diego could soon have a smart water meter, eliminating the human error that led to thousands of erroneous water bills reaching homes.On Monday, the San Diego City Council authorized up to million to buy more than 250,000 smart water meters from company Itron Inc.The move comes after an audit earlier this year found nearly 3,000 erroneous water bills reached households, some spiking to upwards of ,000. The audit largely blamed human error from water-meter readers, who are charged with reading hundreds per day.RELATED: Inside San Diego: Audit shows City sent thousands of faulty water billsThe controversy came to a head when the city discovered one of its meter readers misread 300 meters in Rancho Bernardo, Rancho Pe?asquitos, Mira Mesa and Carmel Valley. That reader was terminated. 853

SAN DIEGO (KGTV) — Even though Americans could start getting vaccinated in days, experts say people who get the shot will still need to wear masks and practice social distancing until scientists can answer a key question: whether immunized people can continue to spread COVID-19.The clinical trials by Pfizer and Moderna showed the two vaccines were about 95 percent effective, but what that really means is they were 95 percent effective at preventing COVID-19 symptoms.The trials did not measure whether vaccinated volunteers got infected without showing symptoms.That means “it is possible and conceivable” that immunized individuals could still be silent spreaders, said Dr. Christian Ramers of Family Health Centers of San Diego. “You’re not going to get sick, but you still get an asymptomatic case, pass it on to your grandmother and kill her.”Both the Pfizer and Moderna vaccines are injected into the arm muscle to stimulate production of antibodies. From there, the antibodies can quickly get to the lungs to fend off severe infection. But experts say the antibodies may have less access to the nose and throat, the primary entry points for the virus.Some studies have suggested that people without symptoms can still have high enough levels of coronavirus in their nose to infect other people.“The vaccine is doing something to prevent disease. We don't really know yet if it prevents transmission,” said Dr. Ramers. “So we have to fall back on all those fundamental things like distancing, masking and washing hands.”Still, experts say there are encouraging clues that vaccinated people may be less contagious. A study in October found antibody levels in the blood were similar to levels in saliva.AstraZeneca had volunteers in its trial test themselves for signs of infection and reported there were fewer asymptomatic cases. However, the company has not yet provided details and its vaccine relies on different technology than Pfizer and Moderna’s mRNA candidates.Until we know more, doctors say vaccinated people will have to keep wearing masks -- potentially until there we achieve herd immunity.“There is modeling to suggest that it will be summer until we reach the point where there are enough people vaccinated that this curve of new cases really starts to go down,” Ramers said.There’s a chance we could get good news before then. Both Pfizer and Moderna say they’ll start testing their volunteers’ blood to reveal if they got infected after vaccination.Pfizer plans to examine a subset of its volunteers. Moderna said it will analyze blood from everyone in the trial.Moderna said it will take several weeks to produce results. 2656

SAN DIEGO (KGTV) -- Former KUSI anchor Sandra Maas is suing the station for million, alleging retaliatory termination and violation of the Equal Pay Act. Maas’ attorneys claim McKinnon Broadcasting Company and the company's actions “have caused, and will continue to cause, Maas emotional distress and loss of earnings."Maas was hired by KUSI in 2004 as a morning news co-anchor. In 2010, she was promoted to evening co-anchor. The lawsuit states Maas initiated additional duties for herself in 2016 when she started writing, producing and anchoring a weekly segment called “Healthy Living.” In 2017, court documents say Maas suspected she was underpaid compared to her male peers. The lawsuit claims her suspicions were confirmed when a former manager told her a male co-anchor was being paid ,000 more than her per year. The lawsuit states that in December of 2017, Maas brought up the issue of pay inequity during contract negotiations and “was given the runaround.” After sending a written complaint to her manager and the station’s general manager, Mike McKinnon Jr., the lawsuit says McKinnon told Maas he “did not like the tone of [her] email.”The last few paragraphs of the lawsuit claim failure to provide equal pay to women, gender and/or age discrimination, failure to prevent discrimination, and retaliation. Maas’s last day at the station was June 13, 2019. Read the full lawsuit below: 1416
