State Street Corridor

State Street Corridor

The State Street/Highway 44 corridor begins in downtown Boise, Idaho, and extends west to connect cities and residents of Canyon County and western Ada County with Boise and each other. Local agencies have been working together to improve the State Street corridor since 2002 based on its regional importance, high transit use, and potential for significant land use changes.

Ten agencies are operating together under a memorandum of understanding to move forward with implementation activities on the State Street/Highway 44 corridor. These agencies are:

These agencies make up the State Street Coordinating Committee, who

…is comprised of collaborative agencies that support and pursue the implementation activities that move these agencies towards the successful long term integration of transit, roadways, and land uses that are the shared vision for the State Street/Idaho 44 Corridor.

What is the State Street corridor?
State Street/Highway 44 extends from downtown Boise to Interstate 84 west of the City of Middleton in Canyon County and is the only east/west roadway north of the Boise River that links these communities in Canyon and Ada Counties. This project focuses specifically on the portion of the corridor from downtown Boise to the State Highway 16 intersection, east of the City of Star.

The regional long-range transportation plan, Communities in Motion, establishes State Street/ Highway 44 as a priority corridor for increased land use densities with a transit emphasis. The plan encourages less sprawl, mixed use development (housing and businesses closer together), and multiple transportation options on the corridor.

What has happened so far?
Local agencies have been planning for improvements along the State Street corridor since 2002. Several transportation options have been analyzed and a market study has been completed. During this time, transit service and ridership have increased and new sidewalks and pathways have been constructed. In addition, the intersection of State Street and Ballantyne Lane has been re-aligned and improved.

Community Advisory Committee of approximately 70 individuals helped shape the Transit and Traffic Operations Plan (see table at the bottom of this page), which was completed in 2011. They helped identify strategies to improve transit performance and traffic operations along the State Street corridor and identified locations for future transit-oriented development. Members' contributions were used to help establish local and regional goals for a long-term transportation plan that will form the basis for future projects on this corridor.

State Street Corridor Strategic Plan Study


The Strategic Plan Study includes near-term improvements necessary along State Street, the vision for how the corridor should evolve over the next 20 years, and an implementation plan to help the multiple jurisdictions responsible for the area to make the vision a reality.

Volume I of the supporting data is an analysis of existing conditions present in the corridor and a look at future conditions if no changes are made in the corridor.

Volume II provides a detailed look at the public involvement process and the findings obtained.

Volume III looks at the analyses used to develop the future scenarios and provides detail about intermediate improvements and future scenario costs.

State Street Corridor Market Strategy (14 MB) 2007 The Market Strategy examines State Street from a market perspective, investigating redevelopment with a focus on transit-oriented development (TOD). It recommends redevelopment at catalyst nodes along the corridor, and a strategy and associated actions for the public sector to consider in support of initiating quality redevelopment at the identified nodes.
State Street Corridor: Transit Oriented Development Policy Guidelines (2.4 MB) 2008 The TOD Policy Guidelines were developed to assist jurisdictions and neighborhoods adjacent to the State Street Corridor to plan and prepare for development of new, active places for people and support efficient transit with high ridership. They include recommendations for site-specific development as well as corridor-wide guidance. The guidelines will also form the basis for future Comprehensive Plan and Land Use Map modifications.
Downtown Boise Multimodal Center Alternatives Analysis (AA) 2009

The eastern terminus of the State Street Corridor is the proposed Downtown Boise Multimodal Center. An Alternatives Analysis was conducted for the multimodal center as part of the Treasure Valley High Capacity Transit Study.

Report of HOV/Park–and-Ride Study Findings and Recommendation (3.5 MB) 2011 The 2011 study developed recommendations for further work on park-and-ride systems and facilities for high-occupancy vehicles (HOV), such as buses, vanpools and carpools. It also suggested more research to find the best options for the region to save travel time and reduce congestion.
Memoranda of Understanding (MOU):





The 2011 Memorandum of Understanding (MOU) continues the commitment and intent of partnering agencies to cooperate and coordinate efforts in the State Street Corridor.

The 2005 MOU grew out of the 2004 Strategic Plan Study (see above) as a key to bring partners together with common goals in the corridor.

State Street Transit and Traffic Operational Plan (TTOP): Task 5 - TOD Site Selection and Prioritization (20 MB)


The State Street Transit and Traffic Operational Plan (TTOP) TOD Site Selection and Prioritization. The TTOP is a multi-part technical study completed in 2010, with all documents posted on the Valley Regional Transit (VRT) website, including this study of potential TOD sites in the corridor

TTOP Implementation Plan:

Due to the large file size of this document, it has been broken into sections for easier downloading:


The State Street TTOP Implementation Plan identifies and prioritizes specific roadway, land use, and transit improvements in line with the vision established in the Strategic Plan Study (2004; see above).  The TTOP implementation is trigger-based and focuses on providing opportunities for auto, transit, walking, and biking; moving people together on an integrated corridor while balancing the livability of existing neighborhoods with planned growth.
