In 2018, the City of Fairfax conducted a trial of a post-election risk-limiting audit in coordination with the City of Fairfax's registrar's office. They presented their process to the State Board of Elections on August 15, 2018. The purpose of this trial (pilot) was to establish a feasible post-election audit process that can be repeated in other localities. You can view their materials from that 2018 presentation for more details.
