What our clients are saying
“The professionals at Raedeke bring a wealth of expertise to every evaluation they do for us. Critical areas often make or break a project. Raedeke provides consistent guidance throughout the regulatory process – from concept, site design, public hearings, construction documents, and final mitigation. Their deep technical knowledge of wetland science and extensive experience experience with jurisdictions brings much surety and consistency to what is otherwise a very inexact process. ”
