The FCEO Survey Department, Records Department, and Tax Map Division were proud to participate in the American Society of Civil Engineers (ASCE) Central Ohio STEM Expo, held at Otterbein University. Our team engaged with students and families, sharing how professional surveyors define property boundaries, map communities, and support the infrastructure projects residents rely on every day. It was a great opportunity to highlight the real-world impact of STEM careers and introduce students to the surveying profession. Thank you to everyone who stopped by to learn more about how surveying helps build and connect our communities!
