US 60 Gonzales Pass

Transportation & Transit // Landscape Architecture Design

As a landscape architecture firm, Logan Simpson has a long history of designing highly sustainable, context-sensitive transportation projects. This award-winning project involved widening approximately 10 miles of US 60 near Superior, Arizona to four lanes. Logan Simpson inventoried more than 35,000 native plants and developed revegetation plans incorporating salvaged trees, various cacti, and a native seed mix. Discussions with the Tonto National Forest determined the appropriate density (and number) of replanted materials. The revegetation at Reymert Wash included planting of salvaged trees to satisfy mitigation requirements in the EA and the CWA Section 404 permit cactus ferruginous pygmy-owl habitat connectivity. Logan Simpson’s Arizona landscape architecture design staff also developed extensive contour grading plans for the cut slopes and designed erosion/sediment control BMPs to meet NPDES requirements. The project earned a President’s Award (Best of Show) Valley Forward; an ADOT Partnering Award; and a Top 10 Project Award from Roads and Bridges Magazine.
