I-70 Programmatic Environmental Impact Statement

Colorado Department of Transportation– Regions 1 and 3
Garfield, Eagle, Summit, Clear Creek, and Jefferson Counties, Colorado
I-70 Programmatic

This Environmental Impact Statement covers a 144-mile corridor from Glenwood Springs to the C-470 interchange in Jefferson County. The client wished to conduct a Tier 1 assessment of the best means of providing future mobility in this corridor serving many national and international recreation destinations. JFSA developed a travel demand model for a study area covering more than half the area of the state of Colorado.

Chaffee and Fremont Counties, Colorado
Over The River

The artists Christo and Jeanne-Claude envision an environmental art exhibit featuring metallic mesh fabric draped over the Arkansas River in Bighorn Sheep Canyon, between Salida and Canon City, Colorado. The JFSA team examined attendance at similar events to estimate visitation during the formal viewing period as well as during installation and removal.

US 34 Environmental Assessment

Larimer County, Colorado
US 34 Environmental Assessment

This Environmental Assessment examined a six-mile corridor from US 287 in Loveland to the Larimer-Weld county line east of I-25. This section of US 34 passes through urban, suburban, and developing rural areas. Forecasts of future volumes and turning movements were developed for about a dozen intersections and the interchange with I-25.

Project Highlights:
  • Added local and collector streets to the North Front Range Metropolitan Planning Organization travel demand model
  • Rationalized zone centroid connections
  • Reconciled factored turning movement counts with forecasts of link volumes
  • Turning movements were used to optimize a coordinated signal timing plan for the corridor
  • Analyzed 6 miles of the US 34 corridor, extending from Loveland to east of Greeley, for intersection design requirements based on traffic operation issues and design LOS requirements
  • Access control for the existing as well as future conditions
  • Detailed traffic safety analysis of the corridor was performed. Direct Diagnostic Methodology was used to identify safety problems.

SH 402, Environmental Assessment (US 287 to I-25)

Colorado Department of Transportation Region 4
Larimer County, Colorado
SH402

Environmental Assessment (EA) for the Colorado Department of Transportation (CDOT) covering this approximately four-mile highway in the southeast part of Loveland, Colorado. The purpose of this project is to improve the mobility and safety of SH 402.

Hogback Parking Facility and Signalized Intersection Design

Colorado Department of Transportation Region 1
Jefferson County, Colorado
Hogback Parking Facility

JFSA conducted an Environmental Assessment (EA) for CDOT that evaluated alternative solutions to provide additional capacity for rideshare opportunities at the Hogback Parking Facility or at other locations that meaningfully serve the I-70 Mountain Corridor. As part of its strategic goals of improving current travel conditions on the I-70 Mountain Corridor and preparing for future growth, the decision was made to expand this facility.
