COVID-19 - Ongoing Updates

March 2020

In response to the COVID-19 pandemic, Governor Newsom issued Executive Order N-33-20 on March 19, 2020 directing all non-critical employees to stay at home and, if possible, work from their residences until further notice. The state of California issued a list of Essential Critical Infrastructure Workers effective March 22, 2020. This guidance indicates the sectors and specific types of businesses that are exempt from Executive Order N-33-20. (covid19.ca.gov/img/EssentialCriticalInfrastructureWorkers.pdf). 


To assist you in your environmental planning, Waterstone has made inquiries with numerous agencies in southern California regarding how each agency is addressing office staffing, meetings, deadlines, and file reviews. As you know, the evolving COVID-19 situation can cause this information to change as the days and weeks progress. Please look to the Waterstone blog for updates.

As Essential Infrastructure workers, Waterstone staff remains available for your needs. We have shifted to a remote working environment and have established guidelines that enable our employees to effectively and efficiently provide customer care remotely and meet our work commitments to you. We will have a skeletal crew in the office to manage the mail, answer the telephones, take and forward client messages, and accept packages and deliveries. Our office staff is committed to facilitating your communications with our staff and other needs while our staff is working from home.
