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 Association of Governments released a report Wednesday showing that bicycle ridership in the county is up more than 40% from 2019, since the statewide stay-at-home order due to COVID-19.Since the start of the order, SANDAG has tracked data to understand how the COVID-19 pandemic has impacted travel in the San Diego region.The data show that with more people staying closer to home, the choice to use alternative transportation for shorter trips, including outdoor opportunities for recreational and fitness activities, continues to increase.The report, titled "Bike Riding in the San Diego Region Since COVID- 19," examines bike volumes on eight corridors around San Diego County between mid-March and mid-August 2020, compared to the same period in 2019. The report also shares biking insights from residents and their plans to continue riding.From April 18 to May 17 -- "Month 2" in SANDAG's data set -- bicycle traffic was up a whopping 66% from 2019, with Month 3 just behind at 62%. As the weather began to heat up and more people headed back to work in their vehicles, the numbers dropped considerably in months 4 and 5, with bicycle traffic volume up 28% and 22% from the previous year.Since 2012, SANDAG has monitored bike travel through counters on the regional bikeway network that measure change in bike volumes over time with continuous counts collected and transmitted every 15 minutes.Since the start of the stay-at-home order, daily volumes increased an average of 42% across the network during the five months in 2020, compared to the same time in 2019.Additionally, biking volumes were up the most on weekends over the five-month period at 53%, compared to weekdays at 35%. Individual corridor increases ranged from 12% on the Landis Street corridor to 62% on the Inland Rail Trail and Mission Road corridor. A total of 84% of residents surveyed who said they were biking more since the pandemic began said they expect to continue biking even when restrictions are lifted.In light of the current public health crisis and in recognition of National Bike Month in May, SANDAG created a new pilot program to support local jurisdictions by giving them the opportunity to designate temporary roadway modifications that create safe spaces for people to bike, walk, run, scoot, use a wheelchair and move during the pandemic.SANDAG awarded 11 jurisdictions funds to help implement temporary Shared Streets pilot projects. The jurisdictions awarded proposed a range of activities such as closing residential streets to through traffic, enhancing signage to alert vehicles of shared streets conditions and closures and creating space for local business patrons to walk, bike and dine outside while maintaining physical distance. 2777
