Okay, let’s tackle this. So Christopher Hogan has a strong background in landscape design, sustainability, and environmental consulting, which are in-demand skills. However, his specific role and location are not explicitly mentioned. Based on national averages for landscape designers and environmental consultants in the Seattle area, I estimate his hourly rate to be around $75. This is lower than the national average for landscape designers ($100-$150 per hour) but higher than the average for environmental consultants ($50-$100 per hour). Considering his skills and location, I've rounded down to $75, but this could be negotiable based on project scope and client budget.
