Transportation Improvement Program

Proposed transportation changes -- submit your comments by January 23!

  • Should I-84 be widened from Nampa to Caldwell?
  • Should the Idaho Transportation Department begin preliminary engineering work to extend State Highway 16 to I-84? (Engineering work will focus on refining the scope, right-of-way needs, and cost estimate for the corridor.)
  • Should Valley Regional Transit begin design work on a transit oriented development in Nampa?

All of these projects are shown as “unfunded” in Communities in Motion 2040, but funding has now been identified to pay for them. For any or all of them to move forward, COMPASS must amend Communities in Motion 2040 and the Regional Transportation Improvement Program (TIP) to show them as “funded.”

COMPASS is requesting your feedback on these proposed amendments, as well as on additional changes proposed for the TIP, including proposals to:

  • Remove funding to expand the Commuteride program in the Nampa Urbanized Area
  • Increase funding for entrance and roundabout improvements at the College of Western Idaho in the City of Nampa
  • Increase funding for a park and ride lot at Piccadilly Park in the City of Middleton
  • Remove a Safe Routes to School coordinator project in Canyon County

Comments will be accepted on any or all of these proposed changes through 11:59 pm, Tuesday, January 23, 2018.

¡COMPASS busca comentarios en cambios de transporte propuestos – envíe sus comentarios antes del 23 de enero!

  • ¿Se debería ampliar la carretera interestatal 84 de Nampa a Caldwell?
  • ¿Debería el Departamento de Transporte de Idaho (ITD) comenzar el trabajo de ingeniería para extender la carretera estatal 16 a la carretera interestatal 84?
  • ¿Debería el Tránsito Regional del Valle (Valley Regional Transit) construir un desarrollo orientado al tránsito?

Se muestran todos estos proyectos como “no financiados” en Las Comunidades en Movimiento 2040, pero ahora se han identificado fondos para financiarlos. Para que cualquiera o todos ellos avancen, COMPASS debe modificar  Las Comunidades en Movimiento 2040, el plan de transporte regional de largo alcance para los condados de Ada y Canyon,y el Programa de Mejoramiento del Transporte Regional (TIP) para que se muestren como “financiados.”

Además, se consideran otros cambios al TIP; se solicitan comentarios sobre estos cambios también:

  • Eliminar los fondos para expandir el programa Commuteride en el área urbanizada de Nampa
  • Aumentar los fondos para las mejoras de la entrada y el círculo de tráfico en el Western Idaho College en la ciudad de Nampa
  • Aumentar los fondos para un estacionamiento para compartir viajes (park and ride) al Parque Piccadilly en la Ciudad de Middleton
  • Eliminar un proyecto coordinador para el proyecto Rutas seguras al colegio (Safe Routes to School) en el condado Canyon

Se aceptarán los comentarios hasta el 23:59 el 23 de enero de 2018.

The Transportation Improvement Program (TIP) is a short-range (3-5 year) capital improvement program (budget) of transportation projects consistent with federal regulations and area policies and strategies. The TIP lists all projects for which federal funds are anticipated, along with non-federally funded projects that are regionally significant. The TIP represents the transportation improvement priorities of the region and is required by federal law. The list includes roadway and public transit projects. For more information contact Toni Tisdale, (208) 475-2238.

COMPASS produces a regional TIP for both the Northern Ada County and Nampa Urbanized Area and updates the document annually. The list of TIP projects must be endorsed by the COMPASS Board. The U.S. Department of Transportation requires that all projects in the TIP be derived from an approved long range transportation plan, meet air quality requirements and be financially constrained to the amount of funds that are expected to be available. The TIP shows the estimated costs and projected construction schedule of transportation projects. The TIP brochure describes in more detail how the TIP is developed. (English/Español)

The Idaho Transportation Department’s Idaho Transportation Investment Program (ITIP) and Ada County Highway District’s Integrated Five-Year Work Plan provide information on additional transportation projects not included in the TIP.

The TIP shows how projects correlate with CIM performance measures. This reporting not only allows a reader to easily see how individual projects help achieve CIM goals, but it also provides additional accountability for the project sponsor and decision-makers, as they must be able to clearly demonstrate the relationship between projects and CIM goals. 

Need assistance in applying for funding? Contact Toni Tisdale (208-475-2238) or Kathy Parker (208-475-2240), or complete a service request form.

Transportation Services Coordination Plans are developed to maximize existing public transportation services, increase the efficiency of those services, and secure additional funding for these services. Specifically, they fulfill a federal requirement to develop a plan to access applicable Federal Transit Administration funds.
