Okay, let’s break it down. Kristen Loughry is a licensed landscape architect (RLA) with a strong educational background from Penn State University. Her skills in sustainable design, site planning, and urban design are in demand. Location is Philadelphia, PA, which has a moderate cost of living. According to the American Institute of Architects (AIA), landscape architects in the Northeast region (where Philadelphia is located) typically charge between $50–$100 per hour. Considering her experience and skills, I estimate her hourly rate to be around $75, which is on the lower end of the range. However, this is a reasonable estimate for a landscape architect with a strong educational background and moderate experience.
