SAN DIEGO (CNS) - San Diego Unified School District officials announced they were making preparations to get children back in schools, but were looking at a timeline of "months, not weeks," before that could become a reality.The district will adopt strict new standards to protect students, staff and the community from the spread of COVID-19 when schools convene in person again, District Superintendent Cindy Marten said during a news conference Monday. The measures are being adopted and developed in consultation with experts from UCSD.In the meantime, the district will begin classes remotely this month.Conditions for reopening local schools will be stricter than state standards, will proceed in phases and will require critical protective measures including mandatory masks, proper ventilation and strict social distancing, according to district leaders.State standards for reopening schools already require a seven-day testing positivity rate of less than 8% and other factors, but the panel convened by San Diego Unified called for adding contact tracing metrics and other factors included in the County of San Diego's designated health triggers."We consulted with the world's leading experts on all aspects of this pandemic because we wanted a comprehensive set of standards to create the safest possible environment for our students and staff," said Dr. Howard Taras, UCSD professor and consulting pediatrician for San Diego Unified. "The strength in these new standards comes precisely from this combination of factors. Taken together, they represent the strictest reasonable conditions for safety when operations eventually resume."According to Taras, San Diego Unified would not consider reopening campuses to in-person study until San Diego County reports fewer than seven community outbreaks of COVID-19 in the previous week and the illness showing up in rates fewer than 100 per 100,000 over the previous two weeks, among other metrics.Marten said the district has purchased more than million in personal protective equipment and has received some 200,000 masks in child and adult sizes from the state, along with 14,000 bottles of hand sanitizer. All schools, Marten said, will follow the strict standards for reopening advised by the UCSD experts. Masks will be required for all students and staff on San Diego Unified campuses."The COVID-19 crisis has radically changed every part of our lives, and schools are no different. We must adapt to this new reality because it may be with us for years to come. That is why we are taking every step necessary to reopen in the safest, most responsible way possible," Marten said. "The fact our country has just passed another grim milestone in the history of this disease -- more than five million confirmed cases, makes it clear this is not yet the right time to begin a phased reopening, but our schools will be readywhen that time comes."President of the San Diego Education Association Kisha Borden agreed with the decision to start the new school year online."We want to get back into our classrooms with our students and we need the support of the entire community to do the right thing by wearing masks, avoiding gatherings, and listening to the science," she said. "The scientific community has made it clear there are no shortcuts on the road to safely reopening schools. We have a long road ahead of us, but we're doing the right things to keep everyone safe."Taras noted that while these guidelines were made using the best information available at the time, they were designed to be flexible with ongoing science on the spread and prevention of the pandemic."Whatever our experts say, it may change in three weeks," he said. 3711

SAN DIEGO (CNS) - The Port of San Diego announced Monday a three-year pilot project to test the use of concrete tide pools as a shoreline stabilizing tool. The concrete company ECOncrete will analyze the efficacy of its concrete tide pools as a possible replacement for traditional shoreline-stabilizing tools like rock armoring. The concrete tide pools will also serve as ecosystems for aquatic animals and organisms that live in natural tide pools. The tide pools interlock like puzzle pieces and are made of low carbon concrete that, according to the company, is environmentally safe and tailored to the environment in which its placed. ECOncrete plans to install 72 of the concrete tide pools across three areas of Harbor Island's shoreline, according to the Port of San Diego. ``ECOncrete's Coastal Star tide pools have great potential to provide many benefits for San Diego Bay,'' said Port of San Diego Board Chair Garry Bonelli. ``The Port looks forward to seeing if they can provide shoreline stabilization, help guard against coastal flooding, and improve the ecology of our bay water.'' The project is the eighth approved in the Port of San Diego's Blue Economy Incubator, which is intended to streamline the process in which businesses can launch pilot projects for so-called blue technology. The port launched the incubator program in 2016 as a way to collaborate with businesses focused on restoring ecosystems, improving water quality and fisheries and monitoring the environment. ECOncrete plans to monitor the tide pools every six months to examine how they could replace current shoreline stabilizers in the San Diego Bay. The best-case scenario, according to the company, would be protecting the city from rising water levels due to climate change while also protecting and sustaining local marine life. ``We are eager to help protect the city's coastlines while increasing resilience and rejuvenating the marine ecosystem of the area,'' said ECOoncrete CEO Shimrit Perkol-Finkel. ``The newly developed Coastal Star tide pool in partnership with the Port of San Diego will help change the way our future coastlines look and function.'' 2162

SAN DIEGO (CNS) - The San Diego Animal Welfare Coalition today will join a nationwide effort to ``Clear the Shelters'' today for the duration of August.The campaign to get as many pets adopted as possible is a little different this year. The Clear the Shelters event, instead of being a single- day effort, will be a month-long adoption drive to allow for virtual adoption consultations by appointment. In addition to promoting adoptions, the campaign encourages donations to participating shelters.``San Diego Humane Society is excited to be working to ``Clear the Shelters,'''' says Gary Weitzman, president and CEO of San Diego Humane Society. ``This important nationwide campaign will give tens of thousands of animals throughout San Diego County a second chance.''Since 2015, the Clear the Shelters campaign has helped more than 410,000 pets find new homes nationwide.``The County of San Diego's Department of Animal Services shelters in Bonita and Carlsbad have many wonderful animals waiting to be adopted into loving homes,'' said Kelly Campbell, director of animal services for the county. ``While the pandemic has certainly created challenges for us all, now may be the perfect time to add a new pet to the family, especially if you find yourself spending more time at home.''The San Diego Humane Society said benefits of adopting a pet include being more affordable, knowing the animal has been assessed for behavior and medical conditions and allowing prospective owners to receive pet-specific resources. The society offers training advice, pet supplies and educational information to support pet families for the lifespan of a pet. ``During the pandemic, we have learned how to embrace change, and that change could include an adoptable pet,'' said Judi Sanzo, president of Rancho Coastal Humane Society. ``Shelters around the country want to remind you that your new best friend could be waiting, tail wagging and ready to join you while you work from home. While Rancho Coastal continues to match pets with their new families, it's important to remember that the virus may be temporary, but pets are a lifetime commitment.'' 2148

SAN DIEGO (CNS) - San Diego Police Chief David Nisleit Tuesday promised a thorough investigation into allegations that one of his officers uploaded a social media post mocking a roadside memorial for a robbery suspect fatally shot three months ago by that lawman and a patrol partner.SDPD Officer Jonathon Lucas was immediately suspended without pay after the online image seemingly belittling the death of 25-year-old Leonardo Hurtado Ibarra appeared on Instagram last week, Nisleit told reporters during a mid-afternoon briefing at downtown police headquarters."I am shocked and disturbed by the reports of this officer's conduct," the chief said about the post, in which emojis of laughing and tearfully wailing faces were superimposed over a photo of the makeshift tribute to Ibarra at the site where he was shot."The officer's alleged actions fall short of the high standards I and our community have for the San Diego Police Department," Nisleit said.Late on the afternoon of June 27, Lucas and Officer Tevar Zaki opened fire on Ibarra, a suspect in a recent robbery, when he allegedly pulled a revolver from his waistband and pointed it at them as they approached him in the 1200 block of Sixth Avenue in the Core-Columbia district.Ibarra succumbed to his gunshot wounds in a hospital two days later.The shooting prompted demonstrations by protesters alleging a culture of excessive use of force and racial bias on the part of the San Diego Police Department.While condemning the antagonistic online posting Tuesday afternoon, the police chief offered a message to Ibarra's survivors."I want to apologize to the Ibarra family," Nisleit said. "This unnecessary act only reopens wounds during an already painful time."In addition to placing Lucas, a four-year member of the SDPD, on unpaid leave, Nisleit revoked his police powers pending completion of the in- house probe into the matter."I want to assure our community that I do not take these allegations lightly," the chief said. "Officers take an oath to protect and value all life. And ... I clearly understand this is a critical time in relationships between law enforcement and the communities that we serve. I want to send a clear message that this behavior is not acceptable in the San Diego Police Department and does not reflect the values of the men and women of this department."Nisleit also pledged to be "transparent with our findings" that result from the internal investigation, though he acknowledged that state law protecting the privacy of police personnel might prevent a full disclosure of any punitive actions -- including, potentially, job termination -- ultimately taken against the accused officer. 2689

SAN DIEGO (CNS) - Parks in Vista will be closed starting Monday in an attempt to limit the spread of coronavirus by encouraging social distancing.The North County city announced the decision on Sunday and had 10 confirmed cases of COVID-19 as of Saturday.The closures include all parks, trails, public restrooms, the South Buena Vista off-leash dog area, athletic fields, basketball courts, pickleball courts, playgrounds, skate parks and tennis courts.Carlsbad, Del Mar, Encinitas, San Diego, Solana Beach, Imperial Beach and the Port of San Diego closed all beaches, trails and parks in their respective cities early last week.San Diego County health officials reported Sunday that five food handlers have tested positive for COVID-19 -- four restaurant employees and a grocery store employee.County Supervisor Nathan Fletcher announced during Sunday's briefing on the coronavirus pandemic that no patients had died in the last 24 hours, leaving the death toll in San Diego County at seven.The county also announced 31 positive COVID-19 cases Sunday, bringing the total number of cases to 519.The highest group of cases, 130, ranged in age from 30-39 and the second highest, 107, in the 20-29 age range.Of the 519 total cases, 219 were female and 298 were male, with 106 people hospitalized and 47 in intensive care, officials said.The grocery store employee who tested positive is from an Albertson's store in Escondido, Fletcher said, adding that the store did the right thing by closing, alerting county environmental health officials, following sanitation protocols, then re-opening to customers."If you have a sick worker, they must stay home," Fletcher said, urging employers to call 858-505-6814 to report any sick workers.Dr. Eric McDonald, the county's medical director of epidemiology, said co-workers of the Albertson's employee who display any symptoms of the coronavirus infection will be sent home, but there are no tests pending in this case.Health officials also stressed that there is no evidence of COVID-19 association with food. They cited the U.S. Centers for Disease Control and Prevention guidelines.Fletcher said that the county is increasing inspections of the many food facilities in the region.Ralphs grocery stores in the county will expand services hours starting Monday. It will be open from 6 a.m. to 7:30 a.m. for senior shoppers age 60 and above, and from 7:30 a.m. to 10 p.m. for the general public.Meanwhile, a Celebrity cruise ship will dock in San Diego Monday."The health of the ship is excellent right now," McDonald said Sunday. County health officials are in continuous contact with the ship's crew for any sign of symptoms, he said.McDonald said 17 cruise passengers are from San Diego County and they will go straight home after disembarking from the ship and will self-quarantine for 14 days. About 1,500 other passengers are from outside the county and they will travel home and self-quarantine after disembarking.Fletcher said a positive meeting was held recently with all hospital CEOs in San Diego where they discussed obtaining more personal protective equipment, the sharing of testing equipment among hospitals and increasing hospital bed capacity.McDonald explained that the number of test results reported may decrease because the labs send those reports to the county electronically and the system is down on the weekends."So, we expect the test result numbers to go down," McDonald said.The doctor also said the risk of contracting the coronavirus disease can increase from vaping and smoking."Any lung disease or condition would put you at risk," McDonald said. "We don't have specific cases so far, but our strong recommendation is to use this opportunity to quit."Fletcher also said the county is issuing a new public health order, extending indefinitely all closure orders that were set to expire March 31.The closure order applies to schools, nonessential businesses, restaurants, gyms and fitness centers, he said, and anyone 65 or older should continue to quarantine themselves at home. 4058
