2025 Transportation Master Plan

Below is a summary of each of the consultant's tasks. You can also view the full consultant scope of work .

DATA COLLECTION & EVALUATION (Aug. 2024 - Oct. 2024)

1. Document and evaluate the Transportation System, including road conditions, traffic volumes, bike/pedestrian and transit infrastructure, crash data, demographic and land use data, growth forecasts and existing plans, policies and standards.
2. Build and utilize a Traffic Demand Model to determine existing and future Level of Service constraints (attach as appendix to the Transportation Needs Assessment)
3. Meet w/ Project Advisory Team and Interview Project Stakeholders

TRANSPORTATION NEEDS ASSESSMENT (Nov. 2024 - Dec. 2024)

1. Growth-driven Improvements.  Evaluate forecast volumes to determine the need for additional capacity (e.g., roadway widening, intersection approach widening, or the need for additional links in the roadway network).  Review the functional classification of existing streets and make recommendations for changes, as needed. Make recommendations for bicycle and pedestrian network links and extensions.
2. SH-33 Corridor Study. Coordinate with ITD on projected intersection controls and cross-section improvements. Review City of Driggs Main Street Improvements plan (completed in 2008) and assess the necessity of removal of SH-33 parking to allow for 4-lane expansion. Provide narrative on intersections, alternative route,  and corridor improvements that could be future projects with ITD.
3. Site-specific Improvements.  In addition to the above system/capacity related improvements, evaluate existing conditions data for the need of site-specific improvements including: roadway geometry, spot safety improvements, spot pavement improvements, structures, pedestrian facility improvements (e.g. sidewalk, pathways), specific streets identified by the City.
4. Maintenance Needs.  Using the provided pavement condition data, develop roadway maintenance / improvement strategies and associated costs for the existing roadway system.  Determine annual roadway maintenance / improvement needs (e.g. chip sealing, overlay, etc.) required to stabilize the condition of the City roadway system.  Include discussion of general maintenance strategies and recommendations for streets, pathways, and parking lots, such as repairing and maintaining edges of pavement and seal coating.  Provide discussion and recommendations of thresholds to convert existing gravel roads within the City to paved roads. Up to three five-year street pavement maintenance funding scenarios will be analyzed.
5. Transit System. Review existing facilities and services. Identify opportunities for improvements and how to better integrate with other modes of transportation. Based on feedback from the advisory committee and the public, identify bus stops and on-demand transit system needs. Also identify Park and Ride lot needs. Include strategies and recommendations in a concise narrative.
6. Roadway Cross-Sections. Provide recommendations for updates to City Standards for roadway cross-sections based on number of lanes, type of street (i.e. land use/zoning location) and functional classification including recommended right-of-way widths, with consideration of complete streets standards and context-sensitive design guidelines. Provide recommendations on how to apply these classifications to new developments.
7. Policy Updates.  Provide recommendations for policy updates on access management, parking, speed limits, street lighting, and truck/freight routes.
8. Public Engagement. Conduct online survey w/ comment mapping tool, and conduct public open house to collect public input on the above topics.

CAPITAL IMPROVEMENT PLAN (Jan. 2025 - Feb. 2025)

1. CIP Development.  Use the needs identified above, comments received, and engineering judgment to develop a combined Capital Improvement Plan for the City. Specific subtasks to be included in this task are:
2. a. Develop planning-level estimates of individual project costs
3. b. Prioritize needs according to safety, mobility, public comment, and funding constraints
4. c. Organize projects into a short term (3 to 5-year), mid-term (6 to 10-years), and long term (20-year) Capital Improvement Plan and identify annual funding needs
5. d. Identify potential funding sources

DRAFT & FINAL PLAN (Feb. 2025 - Mar. 2025)

1. Prepare draft transportation plan and submit to City's Project Advisory Team and Local Highways Technical Assistance Council (funding agency) for comments. City will post the draft for public comments.
2. Revise the draft transportation plan based on comments.
3. Present 2nd draft transportation plan to City Council (City again will post for public comments).
4. Revise plan based on comments and submit final plan for City Council adoption.

ONLINE SURVEY & COMMENT MAP (expected Nov. 2024)

A link will be posted here for the survey and comment map and also included in the City's newsletter and posted to the City's facebook page.

PUBLIC OPEN HOUSE (TBD Dec. 2024 or Jan. 2024)

The Open House will happen after the Needs Assessment is completed. Date/time and location information will be posted here, on the City's online calendar, newsletter and facebook page. The open house will be a "drop-in" style event with one-on-one Q&A with the consultant team. The event is expected to include afternoon and evening hours.

STAKEHOLDER INTERVIEWS (October 2024)

The consultant team will interview up to 10 "stakeholders" representing specific interests in the Driggs transportation system. Two or three slots are available for homeowners associations or organized neighborhood groups. Interested HOA or neighborhood groups can email interest to dself@driggsidaho.org or call Doug Self at 208-354-2362 ext. 2111.

• Consultant Scope of Work
• Project Advisory Team Documents
• Needs Assessment (forthcoming)
• Draft Plan (forthcoming)

The City has created a Project Advisory Team that meets approximately monthly with the consultant team to help guide their work (see meeting docs here ). The members of the Project Advisory Team are: City Planning, Public Works and Community Development Directors, Driggs Mayor, Driggs P&Z Commissioner, Driggs City Council President, Teton County Public Works Director, Idaho Transportation Department District Planner, Teton County Fire Chief, Teton Valley Trails & Pathways Director, Teton Regional Economic Coalition Director, Teton Valley Community Resource Center Director, Teton Adaptive Sports Director.

The City's current transportation plan was originally adopted in 2007, with a 20-year horizon and was last updated in 2019.

The new transportation master plan is funded in part by a grant from the Local Highway Technical Assistance Council's Local Rural Highway Improvement Program. Local-option sales tax is funding the remainder of the consultant contract, which has a not-to-exceed amount of $90,000.
