Study Area and Rio Corridor Context
The Rio Reimagined Active Transportation Study area encompasses an approximately 90-mile regional corridor that follows the Salt River, Gila River, and associated riverine and canal systems across the greater Phoenix metropolitan region. The corridor extends from the eastern communities near Mesa and the Salt River system through Tempe, Phoenix, Tolleson, Avondale, Goodyear, and Buckeye, creating one of the largest active transportation planning efforts ever undertaken in the region. Unlike previous studies that focused on individual river segments or municipal jurisdictions, the Rio Reimagined Active Transportation Study evaluates the corridor as a connected regional system intended to improve bicycle and pedestrian mobility, increase public access to the rivers, and strengthen connections between communities, employment centers, parks, cultural destinations, schools, transit facilities, and regional trail networks.
Rio Reimagined Corridor Context
The Rio Reimagined corridor contains a highly diverse range of environmental and urban conditions. The eastern portions of the study area include more urbanized river segments characterized by levees, transportation infrastructure, mixed-use development, and established recreational destinations such as Tempe Town Lake. Moving westward, the corridor transitions through industrial areas, agricultural landscapes, riparian habitats, floodplain environments, utility corridors, and emerging growth areas. These varying conditions create both opportunities and challenges for implementing a continuous active transportation network. The study therefore evaluates the corridor at both a regional scale and a localized character-area level to ensure that future improvements respond to the unique environmental, cultural, recreational, and community context of each river segment.
Corridor Character Areas and Community Context
While the Rio Reimagined Active Transportation Study establishes a unified vision for a connected regional trail and mobility network, the approximately 90-mile corridor traverses a wide range of environmental, cultural, and urban conditions. These distinct character areas influence trail design, user experience, access opportunities, and implementation strategies. The corridor transitions from remote desert landscapes and floodplain environments to vibrant urban centers, historic communities, tribal lands, recreational destinations, and rapidly growing employment areas. Recognizing and responding to these varying contexts is essential to creating a trail system that reflects the unique identity of each segment while maintaining a cohesive regional experience.
The easternmost reaches of the study area are heavily influenced by the natural landscapes associated with the Tonto National Forest and the upper Salt River watershed. This setting is characterized by rugged desert scenery, mountain views, riparian habitat, and significant ecological resources that contribute to the broader health of the river system. Recreation opportunities associated with hiking, paddling, wildlife viewing, and outdoor tourism define the character of this area. Future pathway and access improvements within this context should prioritize environmental stewardship, habitat protection, scenic preservation, and connections to regional recreation assets while maintaining the natural character that distinguishes this portion of the corridor.
The Mesa segment represents an important transition between the natural river environment and the urbanized communities of the East Valley. Existing canal pathways, parks, neighborhood trail systems, and community destinations provide significant opportunities to connect residents to the broader Rio Reimagined network. The area is characterized by established residential neighborhoods, regional parks, recreational facilities, and growing multimodal transportation infrastructure. The pathway network in this area serves both recreational and transportation functions and provides important connections to educational institutions, employment centers, and regional destinations.
The corridor through the Salt River Pima-Maricopa Indian Community represents one of the most culturally significant portions of the Rio Reimagined study area. The river and surrounding landscape hold deep cultural, historical, and spiritual importance to the Community. This segment is characterized by open desert vistas, agricultural lands, culturally significant resources, and active stewardship of the river environment. Future transportation and recreation improvements within this area will require close coordination with Tribal leadership and should support Tribal priorities related to cultural resource protection, responsible access, environmental preservation, and community connectivity. The SRPMIC segment provides an opportunity to highlight Indigenous history, cultural interpretation, and traditional connections to the river while respecting Tribal sovereignty and sensitive resources.
The Tempe segment is defined by one of the most recognizable and active recreational environments in the region. Anchored by Tempe Town Lake, Arizona State University, and an extensive network of trails, bridges, parks, and entertainment destinations, this area functions as a major regional activity center. The waterfront setting attracts residents and visitors alike and serves as a primary gateway into the broader Rio Reimagined corridor. Future trail investments within this context should emphasize multimodal connectivity, wayfinding, public gathering spaces, recreation, tourism, and connections between the river corridor and adjacent neighborhoods, transit facilities, and employment centers.
The Phoenix portion of the corridor represents the heart of the Rio Reimagined initiative and includes approximately 20 miles of river corridor planned in conjunction with the RIO PHX effort. This segment is characterized by a mix of industrial areas, historic neighborhoods, redevelopment opportunities, public infrastructure, and emerging river-oriented investment. The corridor presents an opportunity to reconnect historically underserved communities to the river through improved trail access, parks, open space, and multimodal transportation facilities. Within this urban context, the Active Transportation Study serves as a critical mobility framework that supports broader community revitalization, economic development, environmental restoration, and public realm improvements envisioned through ongoing city planning efforts.
GRIC is one of the most culturally significant landscapes within the Rio Reimagined corridor. Located along the Gila River south of metropolitan Phoenix, this character area is defined by its strong connection to the river, expansive desert and agricultural landscapes, floodplain environments, and important cultural resources. Future active transportation improvements should emphasize respect for Tribal sovereignty, cultural resource protection, environmental stewardship, and coordination with GRIC priorities related to recreation, connectivity, health, and river restoration. This segment provides an opportunity to celebrate the historic and ongoing relationship between Indigenous communities and the Gila River while supporting long-term preservation of the corridor.
As the corridor transitions westward, the Avondale segment is characterized by a blend of established neighborhoods, community parks, transportation corridors, and natural floodplain environments near the confluence of the Salt and Agua Fria river systems. This area serves as an important regional connection point linking communities across the West Valley. Existing and future trail opportunities have the potential to improve access to open space, strengthen neighborhood connectivity, and create new recreational destinations while preserving sensitive floodplain and habitat resources. The corridor in this area reflects the transition from dense urban development to broader river and desert landscapes.
The Arlington area represents one of the most rural and open portions of the Rio Reimagined corridor. Characterized by agricultural lands, expansive floodplain environments, irrigation infrastructure, and large tracts of undeveloped desert, this segment provides a distinctly different experience from the urban river sections to the east. The landscape offers opportunities for long-distance trail experiences, wildlife observation, environmental education, and appreciation of Arizona’s agricultural heritage. Planning considerations within this area focus on maintaining compatibility with agricultural operations, respecting private property, and preserving the open-space character that defines the region.
The Buckeye character area serves as the western gateway to the Rio Reimagined corridor and includes portions of the Gila River, Hassayampa River, and surrounding desert landscapes. This area is experiencing some of the fastest growth in the metropolitan region and presents significant opportunities to establish a connected trail network before future development occurs. The character of this segment is defined by wide-open desert vistas, mountain backdrops, river corridors, and emerging residential and employment centers. Future investments can help preserve access to natural resources while creating regional connections between growing communities, recreational destinations, and future segments of the Sun Corridor and regional trail systems. The Buckeye segment also offers substantial opportunities for habitat restoration, environmental conservation, outdoor recreation, and long-term economic development associated with a connected regional trail network.
Regional Connectivity
A defining characteristic of the corridor is its ability to serve as a regional active transportation backbone. The plan seeks to bridge existing gaps in bicycle and pedestrian infrastructure while connecting major destinations throughout the metropolitan area. The corridor intersects numerous existing and planned trail systems, including municipal pathways, canal trails, the Maricopa Trail, Sun Corridor Trail concepts, neighborhood greenways, transit investments, and local park systems. By creating a continuous network of pathways, trails, crossings, and access points, the plan supports both recreational use and practical transportation needs, offering opportunities for commuting, tourism, recreation, and healthy outdoor activity.
Environmental and Cultural Resources
The study area also contains significant environmental and cultural resources that influence future planning and implementation. River channels, floodplains, wetlands, riparian habitats, wildlife corridors, archaeological sites, tribal cultural landscapes, and historically significant resources are present throughout the corridor. As a result, the plan emphasizes environmental stewardship, habitat restoration, climate resilience, floodplain compatibility, and cultural resource protection as foundational planning principles. Future trail and access improvements are intended to balance public access with long-term conservation and preservation objectives while supporting the goals of the Urban Waters Federal Partnership and other regional restoration initiatives.
Economic Asset
The corridor is also a significant economic and community development asset. Communities located along the river corridor include many historically underserved neighborhoods as well as emerging employment and development centers. Investments in active transportation infrastructure have the potential to improve access to jobs, parks, educational institutions, transit services, and recreation opportunities while supporting tourism, outdoor recreation economies, and adjacent redevelopment efforts. In this way, the Rio Reimagined Active Transportation Study extends beyond transportation planning to support broader regional goals related to public health, economic vitality, environmental restoration, community connectivity, and quality of life.
Ultimately, the Rio Reimagined Active Transportation Study provides the first corridor-wide framework for establishing a connected regional network across the approximately 90-mile study area. The plan serves as a unifying strategy that coordinates the efforts of multiple jurisdictions, agencies, tribal partners, community organizations, and stakeholders around a shared vision of creating a continuous, accessible, and resilient river corridor.
