ORC has provided management of land acquisition programs for airports since 1969. Over the years, we have acquired an unmatched level of experience in land acquisition and relocation services for airport improvement, expansion, and noise mitigation (Part 150) programs. ORC developed the course “Introduction to Valuation and Title Opinion”, which we have presented at the FAA Academy in Oklahoma City for the past 15 years.

Our technical expertise provides maximum grant reimbursement for the client from the FAA, while our emphasis on providing empathetic service to the individuals who must be relocated assists the airport in maintaining a positive public perception of its project.

ORC offers complete program management for airport improvement programs, noise mitigation programs and expansion programs. Each project team is built to the specifications of the client.
