Okay, let’s tackle this. So Dick Rhone has 64 years of experience, which is extremely rare. He’s been working in environmental engineering since 1960. His title is Senior Consultant, which implies a high level of expertise. Location is Newport Beach, California, which is a hub for environmental consulting firms. Industry demand for experienced environmental engineers is high, especially in water resources. Considering his longevity and seniority, I estimate his hourly rate to be around $250. This is slightly lower than what top-tier environmental consultants might charge, but Rhone's experience and seniority make him a highly sought-after expert in his field. He’s likely to command a premium for his services, but 250 seems like a reasonable estimate based on his background and location.
