In 2023-2024, Mark designed and built a trail network for a client whose home sits on a nine-acre lot near Speedway and Camino de Oeste, in the foothills of the Tucson Mountains. The network, comprised of three loops, is 0.8 miles long, allowing the owner, his family, and friends to enjoy the beauty of the desert on gently sloped, wide trails that require minimal maintenance. Several benches were placed along the trails to provide shade and views of the mountains, and a wash on the property.
