Parkhill partnered with award-winning Schrickel|Rollins landscape architecture firm in the master planning of a Westside regional park site. Since then, the two firms have merged. The City of El Paso selected SR to provide master planning for the park, detailed design of the recreation facilities and landscape development. Parkhill provided site planning and design services to develop a conceptual site plan that would satisfy arroyo advocates as well as hikers and bikers thirsty for new trails, and that would be a beneficial use of precious open space. The trails were left in their original state to preserve the plant life and wildlife found within the Mulberry Reservoir.
