The City of North Chicago City-wide Emergency Water Main Repairs Project received the 2026 APWA Chicago Metro Chapter Project of the Year Award in the Disaster or Emergency Repair category. After a critical transmission main ruptured in September 2025, city crews and partners coordinated rapid repairs across the system while maintaining continuous water service. Trotter and Associates, Inc. was part of the broader project team supporting the City of North Chicago Public Works, alongside Campanella and Sons Inc., and Thompson Pipe Group, whose combined efforts made the response possible.

Madeline Tiedt joined Trotter and Associates, Inc. in January as a full-time Staff Engineer working with the Civil Team in the St. Charles office. Madeline, a Purdue University graduate in Environmental and Natural Resource Engineering, brings experience in environmental site assessments, field sampling, hydrologic modeling, and watershed analysis. Her academic work included international projects focused on sustainable agricultural systems, and she served as a mentor in Purdue’s Women in Engineering organization. We’re proud that Madeline is building her career at TAI and contributing to the firm’s growing Civil Team!

Erika Salisbury returns to Trotter and Associates, Inc. as a full-time staff engineer in our St. Charles, IL office. After interning with TAI’s Water/Wastewater Team last summer — where she assisted with force main profiles, IL EPA permit submittals, and construction specification updates — Erika earned her Environmental and Ecological Engineering degree from Purdue University. In September, just before graduation, she passed the Fundamentals of Engineering (FE) exam, earning her Engineer-in-Training (E.I.T.) certification. It is no surprise that Erika has already re-engaged in active projects, bringing both continuity and technical discipline to the team. We are proud to welcome her back to TAI, where she will advance her career while supporting our projects and valued clients.
