The Central Arizona Project (CAP) aqueduct extends 336 miles across the State of Arizona from Lake Havasu to the Tohono O’Odham Reservation near Tucson. The aqueduct and the associated rights-of-way create a corridor that is conducive to trail development and that connects various communities in Maricopa, Pinal, and Pima Counties. The trail has been designated by the U.S. Secretary of the Interior as a part of the National Recreation Trail system that extends through all 50 states. McGann & Associates collaborated with Pima County and Pinal County and prepared master plans for those portions of the CAP trail passing through these jurisdictions. In total, the firm has been responsible for the detailed planning of more than 150 miles of trail along the CAP.

The Loop is a 131 mile long non-motorized, multiple-use trail that extends around the perimeter of the Tucson metropolitan area. Improvements associated with the Loop include a paved shared-use pathway, a parallel soft-surface trail, staging areas, and access nodes. McGann & Associates successfully coordinated the planning and design of several segments of the Loop including portions that extend long the Santa Cruz River, the Rillito River, Pantano Wash, and Canada del Oro Wash. Serving as both the prime consultant and landscape architectural subconsultant on these projects, the firm coordinated the design of recreational facilities, habitat improvements, and associated irrigation system development.

Gila River Linear Park and Trail Master Plan was completed in June 2020 for a 7.5-mile linear park along the Gila River just outside of Safford and Thatcher. McGann & Associates, along with the Gila Watershed Partnership, and the Trust for Public Land prepared the conceptual master plan for this linear park. The master plan features a non-motorized shared-use pathway, overlook areas, access to the river’s edge, drainage improvements, ramadas and restrooms, riparian habitat restoration, and interpretive areas.
