Okay, let’s tackle this. So Yan Xu has a strong skill set in landscaping, urban planning, and design. He’s also got a LEED GA certification, which is a well-respected credential in the field. Location is the San Francisco Bay Area, which is known for being competitive. Landscape designers and urban planners with LEED certification can command higher rates. According to the Bureau of Labor Statistics, the median annual salary for landscape architects in the Bay Area is around $95,000. However, with a LEED certification, Yan could potentially charge more. Let’s look at some benchmarks. Landscape designers with similar experience and skills might charge $75–$125 per hour. Considering his certification and location, I’ll estimate around $100–$150 per hour. But to be on the safe side, I’ll round down to $125.
