Traffic Calculations

A new Traffic Impact Study was included in the updated Variance Posted on December 12. 

Following describes the changes made. We assume these were made in response to Referral agency and Public Comment.

The file dated December 10, 2025 (URL: https://drive.google.com/file/d/19_OOfTIyglRXOnNSN255yHqmQy0_3PSE/view?usp=drive_link), represents a significant update from the August 25, 2025, version. Key changes include updated technical data, revised development plans, and expanded appendices.

1. Core Project Revisions

The primary changes to the project scope between August and December include:

• Unit Mix Adjustment: The December study now specifies 111 units of affordable workforce housing, subdivided into 93 multifamily units and 18 townhomes.

• Affordable Housing Designation: The project is now explicitly evaluated as "Affordable Housing" (ITE Land Use Code 223) due to the "presence of transit opportunities and connections in the area," which impacts the trip generation logic compared to standard residential categories.

2. Updated Traffic Data and Projections

The technical analysis has been refined with more recent and comprehensive data:

• Buildout Horizons: The analysis has been updated to focus on the 2028 short-term buildout and the 2050 long-term horizon.

• Trip Generation: Based on the new unit count (111), the study calculates 534 weekday daily trips, with 40 trips in the AM peak and 51 in the PM peak.

• Intersection Analysis: Specific focus is added to the SH-82 and El Jebel Road intersection, including new projections that it may require three lanes in each direction by 2040.

3. Enhanced Appendix Documentation

The December version includes several new or significantly updated appendices:

• Appendix A (Conceptual Site Plan): Features updated architectural drawings from JMD LLC / LivD, showing precise unit type matrices for floors 1–3, including ANSI Type B accessibility counts.

• Appendix D (Access Diagram): Includes a new map from Sopris Engineering LLC showing the "Main Site Access" and "Secondary Ingress/Egress" points relative to J W Drive and Gillespie Drive.

• Appendix E (Drainage and NOAA Data): Adds detailed environmental and infrastructure data, including NOAA Atlas 14 Point Precipitation Frequency Estimates for El Jebel and NRCS Soil Surveys.

4. Regulatory and Safety Compliance

• MUTCD Standards: The updated report explicitly cites compliance with the 11th Edition (2023) of the Manual on Uniform Traffic Control Devices (MUTCD) for all onsite and offsite improvements.

• Transit and Pedestrian Connectivity: New details have been added regarding the Roaring Fork Transit Authority (RFTA) BRT bus stop locations and the construction of a continuous pedestrian pathway connecting the development to the existing pedestrian underpass beneath SH-82.
