The Engineering Technician III also assists with outreach and training for contractors, businesses, municipal staff, students, and members of the public on stormwater best management practices (BMPs) and pollution prevention measures.

The position requires the use of office software, Geographic Information Systems (GIS), asset management, and database tools to track stormwater facilities, inspections, and enforcement actions, as well as to support program documentation and reporting.
